By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/COPYRIGHT b/COPYRIGHT new file mode 100644 index 0000000..7400d7d --- /dev/null +++ b/COPYRIGHT @@ -0,0 +1,46 @@ +Copyright (c) 1990,1996 Regents of The University of Michigan. +All Rights Reserved. + + Permission to use, copy, modify, and distribute this software and + its documentation for any purpose and without fee is hereby granted, + provided that the above copyright notice appears in all copies and + that both that copyright notice and this permission notice appear + in supporting documentation, and that the name of The University + of Michigan not be used in advertising or publicity pertaining to + distribution of the software without specific, written prior + permission.

We now use per Volume configurable + CNID backends. +* NEW: Two new daemons, cnid_metad and cnid_dbd to implement the dbd CNID backend. + Using Berkeley DB transactions with the CNID database should be safe now. +* NEW: The on disk format of the CNID database has changed. We now support 8 byte + device and inode numbers and an additinal type field that should make + detection of file/directory changes outside of afpd more robust. + Changed from HASH to BTREE access which speeds things up in certain cases + and reduces database file size. +* NEW: Long file name mangling is now implemented using the CNID ID, so no database is + required to map names to mangled names. This is the same method Mac OS X uses. +* NEW: New format (version 2) for Metadata in AppleDouble files. We record device and + inode of the underlying file as well as the CNID. This can be used for recovery + and speeds up access to the CNID. +* NEW: The old NLS codepage system has been removed. It was replaced by an iconv + based conversion system, which provides much more flexibility. +* NEW: You can safely use extended characters in volume names and for SIGUSR2 messaging. +* NEW: The default volume encoding is UTF-8. +* NEW: All documentation is now generated using DocBook. New or completely reworked + sections about installing, setting up and upgrading Netatalk replace various + README files in the doc directory. +* FIX: Protect afpd better against unexpected signals during updates of the CNID + database with the cdb backend. This makes database corruption less likely. +* FIX: All manpages have been reviewed and should now be up to date. +* FIX: Tons of bug fixes since 1.6.4. Please consults the CVS change log for details. + +Changes in 1.6.4 +================ + +* NEW: afpd: Using the mswindows option now implicitly specifies usedots. + [Sam Noble] +* UPD: afpd.8: Updated the option documentation. + [Thomas Kaiser, Sebastian Rittau] +* FIX: configure: Removed broken --with-flock-locks option.

This + should be heavily tested in a multiuser environment. +* NEW: Variable substitution support has been added for the dbpath AppleVolume + option. +* UPD: CNID DID handling is now enabled by default. +* FIX: Various bug and build fixes as well as code cleanups. + +Changes in 1.5.5 +================ + +* NEW: Allow afpd debugging to be enabled by sending the afpd process + a SIGUSR1. +* NEW: Allow SLP to be disabled per afpd process by adding a new -noslp flag + to afpd.conf. +* FIX: Use server name (if not NULL) for the SLP URL. +* FIX: papd: buffer overflow during config file read (Olaf Hering) + +Changes in 1.5.4 +================ + +* FIX: File open read only and then read write (aka pb with Illustrator). +* FIX: Problems with unexpected EOF when reading files on a ddp connection + Photoshop, old finder. +* FIX: --with-nls-dir option does now work + +Changes in 1.5.3 +================ + +* UPD: Extend the --disable-shell-check functionality to ignore users + with _no_ shell. Also, send a log message if a user is refused login + based on the fact that they have no shell. +* UPD: Autoconf updates. +* UPD: Tru64 afpd authentication updates. +* UPD: As always: lots of minor code cleanups. +* FIX: Problems with Photoshop trying to open image files has been + corrected. +* FIX: Preserve special permission bits when creating or modifying + directories. +* FIX: afp_deleteid() now deletes the specified file and not the parent + directory. +* FIX: papd does now announce that it supports binary data to its clients. +* FIX: NetBSD ELF support. +* FIX: acleandir.rc is now installed in the bin directory. +* FIX: megatron does now compile even if compiled with -DDEBUG. +* FIX: Clean up some syslog messages. + +Changes in 1.5.2 +================ + +* NEW: NetBSD support contributed by David Rankin and NetBSD contributors. + This includes a new configure option --enable-netbsd. +* NEW: Add the -client_polling afpd.conf flag to allow for clients to poll + the server every 10 seconds for open window updates. Currently + this is the only way to get asynchronous directory updates. +* UPD: Use separate macro for AFS configure check. +* UPD: Some Perl scripts are now (partially) auto-generated. This improves + out-of-the-box usage of Netatalk. +* UPD: Solaris Kernel Makefile is now auto-generated. This fixes some path + issues, but isn't perfect, yet. Added some Solaris compatibility + fixes to the Kernel sources, too. +* UPD: CNID DB code sync'd with the current CVS version. NOTE: Using this + code requires you to delete _all_ existing .AppleDB directories in + order to avoid database corruption! +* FIX: The file AppleVolumes.system contained wrong line breaks so that + not all file types were properly recognized. +* FIX: AFS compilation would fail due to a misnamed variable. +* FIX: SLP configure check was wrong so SLP did not compile. +* FIX: Fix the way quotas are handled under certain situations. +* FIX: Do not enable debugging code if debugging option is not set. +* FIX: Some problems with wrongly assigned DIDs were fixed. +* FIX: Various bug fixes and code cleanups. + +Changes in 1.5.1 +================ + +* NEW: Added a program called cnid_didname_verify that can be used to + verify the consistency of the CNID database. +* NEW: New afpd option: -timeout. Warning: This still doesn't do what it's + supposed to! +* UPD: Code cleanups and compatibility fixes to macusers. +* UPD: AppleVolumes.system was cleaned up. +* FIX: Really fix Tru64 compilation (see last entry). +* FIX: Hand correct error value back to AFP client when deleting files or + directories fails. +* FIX: Leading or trailing spaces are now forbidden on volumes that have + the AFPVOL_MSWINDOWS flag set. +* FIX: Minor code cleanups and warning fixes. +* FIX: Make quota support work on FreeBSD. + +Changes in 1.5.0 +================ + +* FIX: Compilation on Tru64 systems was broken, since libtool's acinclude.m4 + file on the packagers system did not contain the necessary patch. +* FIX: On some systems, atalkd refuses to start, since it couldn't detect + any interfaces. This was caused by an overzealous validity check. + +Changes in 1.5rc2 +================= + +* FIX: contrib/shell_utils/lp2pap.sh was erased when "make clean" was called. + Now we distribute lp2pap.sh.tmpl instead, and lp2pap.sh is automatically + generated during package build. +* FIX: Some platforms (notably Tru64) don't have the snprintf() call, which + was used in etc/afp/afp_config.c. This call was replaced by sprintf() + and prior bounds checking. + +Changes from the 1.4b1 release: +=============================== + +* Fixed the maximum free/total volume size in afpd. + +* Made ~ the default volume in afpd. + +* Fixed pid file handling and changed setpgrp() to setpgid() in afpd, + papd, and atalkd. + +* Added code to afpd to set the Unix file time stamps with utime(). + +* Fixed a bug in papd's printcap code which limited it to 15 or so + printers. + +* Fixed papd's handling of piped printers. + +* Fixed papd's handling of bad job names. + +* Fixed atalkd to send NBP LKUP packets from NBP port. + +* Added "sync;sync;sync" to Solaris kinstall to help with streams + file corruption. + +* Added nlocalrts to streams ddp.conf. Thanks Thomas Tornblom. + +* Fixed signed extension infinite loop in Solaris module. + +* Moved all the config files to .../config. + +Changes from the 1.3.3 release: +=============================== + +* Added code from Sun Microsystems, Inc (OPCOM) for Solaris support. + See COPYRIGHT. + +* Added support for FreeBSD, mostly changes by Mark Dawson and Julian + Elischer. + +* All sorts of other stuff. + +Changes from the 1.3.1 release: +=============================== + +* Added options to psf's filter names to support accounting on HPs. + !!! NOTE: The location of the filters has changed, see the man + page for where. + +* Added code from Alan Cox to support Linux. + +* Rewrote papd. Now handles dropped connections better. + Configuration has been modernized. !!! NOTE: The format of the + configuration file has changed, but NOT THE NAME. + +* Added Kerberos support to papd. + +* atalkd now removes routes on a SIGTERM. Still can't just restart + it, but it's closer. + +* Changed atalkd and the kernel driver to remove a hack added to + support sending to 0.255. Now the kernel will allow multiple open + sockets with the same port, so long as the addess associated with + the port is different. atalkd now opens a socket for each port on + each interface. + +* atalkd now rewrites its configuration file. If no configuration + file is given, one will be generated. Permissions on the new + configuration file will be inherited from the old one. If there is + no old one, permissions default to 644. Won't rewrite the file if + the owner doesn't have write permission. + +* Removed support for the "AFS Kerberos UAM", in favor of the + "AuthMan UAM". Kerberos support should now be much more + straight-forward. + +* Fixed a bug in afpd which would cause incorrect group calculations + on ultrix machines. + +* Fixed a bug in afpd which causes SimpleText and some other + applications to silently fail to write. There's also a bug in + MacOS, but we can't fix that. + +* Fixed a bad interaction with afpd and AFS which would cause file + writes to not propogate between AFS clients. + +* !!! CHANGED the name(s) of afpd's config files. The new files are + AppleVolumes.system and AppleVolumes.default. If AppleVolumes.system + exists, it is always read, AppleVolumes.default is only read if the + user has no AppleVolumes file. Included a flag "-u" to indicate + which file has precedence. "-u" user wins, otherwise ".system" + wins. + +* Rewrote the AppleVolumes parsing code. Now works. + +* Added a filename extension mapping to afpd. User always takes + precedence, regardless of the "-u" flag. Code to change the type + of all Unix files contributed by Kee Hinckley . + +* afpd now supports both UFS and AFS volumes simultaneously. It also + uses access() to attempt to calculate reasonable Mac permissions + for AFS directories. + +* Changed reporting of file times. Files that are written from Unix + now update the Mac's idea of the files modification time. Unix + mtime is now reported instead of ctime. + +* Added support for a new UAM to afpd. This requires that client + Macs have MacTCP and AuthMan installed. Should make running afpd + for AFS easier. + +* Removed code so that otherwise valid volumes for which the mounting + user has no permission will appear in the volume selection dialog + on the Mac gray-ed out. + +* Added code from Chris Metcalf of MIT to the AppleDouble library + which improves permission inheritance. + +* Added code from G. Paul Ziemba of Alantec, Inc to better report + errors in psf. Also changed psf to use syslog for errors that + users aren't interested in. + +* Added information to psf's man page to better explain the + interaction between psf, pap, and lpd. + +* Make psf/pap/psa do accounting when it's turnes on in + /etc/printcap. + +* Changed pap's error message when there is no printer specified on + the command line and no .paprc is found. Also heavily modified + pap's man page to reflect changes in the "new" version of pap, + including moving it from section 8 to section 1. + +* Fixed a byte-order bug in pap's sequence numbers. Doubt if pap has + ever worked right on little endian machines! + +* Added a flag to pap to optionally close before receiving EOF from + the printer. Off by default. psf calls pap with this option on. + +* Added timeouts to the nbp library calls. This means that processes + won't hang when atalkd dies during boot, thus hanging your + machine. + +Changes from the 1.3 release: +============================= + +* Fixed a bug in afpd which would cause APPL mappings to contain both + mac and unix path names. The fixed code will handle the old + (corrupted) database. + +* Fixed a *very* serious bug which would cause files to be corrupted + when copying to afpd. + +* Fixed a bug in afpd which would cause replies to icon writes to + contain the written icon. + +* Filled in the function code switch in afpd. Previously, a hacker + could probably have used afpd to get unauthorized access to a + machine running afpd. + +* Fixed a bug in the asp portion of libatalk.a which could cause the + malloc()/free() database to be corrupted. + +* Fixed a bug in atalkd's zip query code. With this bug, only the + first N % 255 nets get queried. However, since nets bigger than + 255 are usually pretty unstable, the unqueried for nets will + eventually get done, when N drops by one. + +* Suppressed a spurious error ("route: No such process") in atalkd. + +Changes from the 1.2.1 release: +=============================== + +* atalkd is completely rewritten for phase 2 support. atalkd.conf + from previous version will not work! + +* afpd now has better AFS support. In particular, the configuration + for AFS was made much easier; a number of Kerberos-related + byte-ordering and time problems were found; clear-text passwords + were added (thanks to geeb@umich.edu). + +* afpd now handles Unix permissions much better (thanks to + metcalf@mit.edu). + +* There are many, many more changes, but most are small bug fixes. + +Changes from the 1.2 release: +============================= + +* The Sun support now uses loadable kernel modules (a la VDDRV) + instead of binary patches. As such, it should work on any sunos + greater than 4.1, and is confirmed to work under 4.1.1 and 4.1.2. + +* The DEC support no longer requires source. It also runs under + ultrix 4.1 and 4.2. It still requires patching your kernel, but the + patches are limited to those files available to binary-only sites + -- primarily hooks for things like netatalk. + +* The etc.rc script now uses changes made to nbprgstr (see below). + +* aecho now takes machine names on the command line. + +* nbplkup now takes a command line argument specifying the number of + responses to accept. It also takes its defaults from the NBPLKUP + environment variable. + +* nbprgstr may be used to register a name at any requested port. + +* afpd now logs if an illegal shell is used during login, instead of + silently denying service. + +* A bug in afpd which caused position information for the directory + children of the root of a volume to be ignored has been fixed. + +* Several typos in afpd which would cause include files necessary to + ultrix to be skipped have been fixed. + +* atalkd will no long propagate routes to networks whose zone + it doesn't know. + +* atalkd no longer dumps core if it receives a ZIP GetMyZone request + from a network whose zone it doesn't know. (Since this currently + can only happen from off net, it's not precisely a legal request.) + +* pap and papd (optionally) no longer check the connection id in PAP + DATA responses. Both also maintain the function code in non-first-packet + PAP DATA responses. These changes are work-arounds to deal with + certain AppleTalk printer cards, notably the BridgePort LocalTalk + card for HP LJIIISIs. + +* pap no longer sends an EOF response to each PAP SENDDATA request, + only the first. + +* A bug in papd which would cause it to return a random value when + printing the procset to a piped printer has been fixed. + +* A bug relating to NBP on reverse-endian machines has been fixed. + +* atp_rsel() from libatalk now returns a correct value even if it + hasn't recieved anything yet. + +* atalk_addr() from libatalk no longer accepts addresses in octal + format, since AppleTalk addresses can have leading zeros.

The mechanisms to resolve such + inconsistencies may fail sometimes, though, as this is not an easy task to + accomplish. I.e. if several names in the path to the file or directory + have changed, things may go wrong. + + If you change a lot of filenames at once, chances are higher that + the afpds fallback mechanisms fail, i.e. files will be assigned new IDs, + even though the file hasn't changed. uniconv + therefore updates the CNID entry for each file/directory directly after it + changes the name to avoid inconsistencies. The two supported backends for + volumes, dbd and cdb, use the same CNID db format. Therefore, you + could use uniconv with cdb and + afpd with dbd later. + + Warning: There must not be two + processes opening the CNID database using different backends at once! If a + volume is still opened with dbd (cnid_metad/cnid_dbd) and you start + uniconv with cdb, the result will be a corrupted CNID + database, as the two backends use different locking schemes.

afp.conf + + 5 + + 06 Aug 2014 + + @NETATALK_VERSION@ + + + + afp.conf + + Netatalk configuration file + afp.conf + + + + + SYNOPSIS + + The afp.conf file is the configuration file for + the Netatalk AFP file server. + + All AFP specific configuration and AFP volume definitions are done + via this file. + + + + FILE FORMAT + + The file consists of sections and parameters. A section begins with + the name of the section in square brackets and continues until the next + section begins. Sections contain parameters of the form: + name = value + + + The file is line-based - that is, each newline-terminated line + represents either a comment, a section name or a parameter. + + Section and parameter names are case sensitive. + + Only the first equals sign in a parameter is significant. Whitespace + before or after the first equals sign is discarded. Leading, trailing and + internal whitespace in section and parameter names is irrelevant. Leading + and trailing whitespace in a parameter value is discarded. Internal + whitespace within a parameter value is retained verbatim. + + Any line beginning with a semicolon (;) or a hash + (#) character is ignored, as are lines containing only + whitespace. + + Any line ending in a \ is + continued on the next line in the customary UNIX fashion. + + The values following the equals sign in parameters are all either a + string (no quotes needed) or a boolean, which may be given as yes/no, 1/0 + or true/false. Case is not significant in boolean values, but is preserved + in string values. Some items such as create masks are numeric. + + The parameter allows you to include one config + file inside another. The file is included literally, as though typed in + place. Nested includes are not supported. + + + + SECTION DESCRIPTIONS + + Each section in the configuration file (except for the [Global] + section) describes a shared resource (known as a volume). + The section name is the name of the volume and the parameters within the + section define the volume attributes and options. + + There are two special sections, [Global] and [Homes], which are + described under special sections. The following notes + apply to ordinary section descriptions. + + A volume consists of a directory to which access is being given plus + a description of the access rights which are granted to the user of the + service. For volumes the option must specify the + directory to share. + + Any volume section without option is + considered a vol preset which can be selected in + other volume sections via the option and + constitutes defaults for the volume. For any option specified both in a + preset and in a volume section the volume section + setting completely substitutes the preset option. + + The access rights granted by the server are masked by the access + rights granted to the specified or guest UNIX user by the host system. The + server does not grant more access than the host system grants. + + The following sample section defines an AFP volume. The user has + full access to the path /foo/bar. The share is + accessed via the share name baz: [baz] + path = /foo/bar + + + + SPECIAL SECTIONS + + + The [Global] section + + Parameters in this section apply to the server as a whole. + Parameters denoted by a (G) below are must be set in this + section. + + + + The [Homes] section + + This section enable sharing of the UNIX server user home + directories. Specifying an optional parameter + means that not the whole user home will be shared but the subdirectory + . It is necessary to define the option. It should be a regex which matches the parent + directory of the user homes. Parameters denoted by a (H) belong to + volume sections. The optional parameter can + be used to change the AFP volume name which $u's + home by default. See below under VARIABLE + SUBSTITUTIONS. + + The following example illustrates this. Given all user home + directories are stored under /home: + [Homes] + path = afp-data + basedir regex = /home For a user + john this results in an AFP home volume with a path + of /home/john/afp-data. + + If contains symlink, set the + canonicalized absolute path. When /home links to + /usr/home: [Homes] + basedir regex = /usr/home + + + + + PARAMETERS + + Parameters define the specific attributes of sections. + + Some parameters are specific to the [Global] section (e.g., + log type). All others are permissible only in volume + sections. The letter G in parentheses indicates that + a parameter is specific to the [Global] section. The letter + V indicates that a parameter can be specified in a + volume specific section. + + + + VARIABLE SUBSTITUTIONS + + You can use variables in volume names. The use of variables in paths + is limited to $u. + + + + if you specify an unknown variable, it will not get + converted. + + + + if you specify a known variable, but that variable doesn't have + a value, it will get ignored. + + + + The variables which can be used for substitutions are: + + + + $b + + + basename + + + + + $c + + + client's ip address + + + + + $d + + + volume pathname on server + + + + + $f + + + full name (contents of the gecos field in the passwd + file) + + + + + $g + + + group name + + + + + $h + + + hostname + + + + + $i + + + client's ip, without port + + + + + $s + + + server name (this can be the hostname) + + + + + $u + + + user name (if guest, it is the user that guest is running + as) + + + + + $v + + + volume name + + + + + $$ + + + prints dollar sign ($) + + + + + + + EXPLANATION OF GLOBAL PARAMETERS + + + Authentication Options + + + + ad domain = DOMAIN + (G) + + + Append @DOMAIN to username when authenticating. Useful in + Active Directory environments that otherwise would require the + user to enter the full user@domain string. + + + + + admin auth user = user + (G) + + + Specifying eg "" + whenever a normal user login fails, afpd will try to authenticate + as the specified . If this + succeeds, a normal session is created for the original connecting + user. Said differently: if you know the password of , you can authenticate as any other user. + + + + + k5 keytab = path + (G) + + k5 service = service + (G) + + k5 realm = realm + (G) + + + These are required if the server supports the Kerberos 5 + authentication UAM. + + + + + nt domain = DOMAIN + (G) + + nt separator = SEPARATOR + (G) + + + Use for eg. winbind authentication, prepends both strings + before the username from login and then tries to authenticate with + the result through the available and active UAM authentication + modules. + + + + + save password = BOOLEAN (default: + yes) (G) + + + Enables or disables the ability of clients to save passwords + locally. + + + + + set password = BOOLEAN (default: + no) (G) + + + Enables or disables the ability of clients to change their + passwords via chooser or the "connect to server" dialog. + + + + + uam list = uam list + (G) + + + Space or comma separated list of UAMs. (The default is + "uams_dhx.so uams_dhx2.so"). + + The most commonly used UAMs are: + + + + uams_guest.so + + + allows guest logins + + + + + uams_clrtxt.so + + + (uams_pam.so or uams_passwd.so) Allow logins with + passwords transmitted in the clear. (legacy) + + + + + uams_randum.so + + + allows Random Number and Two-Way Random Number + Exchange for authentication (requires a separate file + containing the passwords, either @pkgconfdir@/afppasswd file or + the one specified via "". See + + afppasswd + + 1 + for details. (legacy) + + + + + uams_dhx.so + + + (uams_dhx_pam.so or uams_dhx_passwd.so) Allow + Diffie-Hellman eXchange (DHX) for authentication. + + + + + uams_dhx2.so + + + (uams_dhx2_pam.so or uams_dhx2_passwd.so) Allow + Diffie-Hellman eXchange 2 (DHX2) for authentication. + + + + + uam_gss.so + + + Allow Kerberos V for authentication (optional) + + + + + + + + uam path = path + (G) + + + Sets the default path for UAMs for this server (default is + @libdir@/netatalk). + + + + + + + Charset Options + + With OS X Apple introduced the AFP3 protocol. One of the big + changes was, that AFP3 uses Unicode names encoded as Decomposed UTF-8 + (UTF8-MAC). Previous AFP/OS versions used charsets like MacRoman, + MacCentralEurope, etc. + + To be able to serve AFP3 and older clients at the same time, + afpd needs to be able to convert between UTF-8 and + Mac charsets. Even OS X clients partly still rely on the mac charset. As + there's no way, afpd can detect the codepage a pre + AFP3 client uses, you have to specify it using the option. The default is MacRoman, which should be fine + for most western users. + + As afpd needs to interact with UNIX operating + system as well, it need's to be able to convert from UTF8-MAC / Mac + charset to the UNIX charset. By default afpd uses + UTF8. You can set the UNIX charset using the + option. If you're using extended + characters in the configuration files for afpd, make + sure your terminal matches the . + + + + mac charset = CHARSET + (G)/(V) + + + Specifies the Mac clients charset, e.g. + MAC_ROMAN. This is used to convert strings + and filenames to the clients codepage for OS9 and Classic, i.e. + for authentication and AFP messages (SIGUSR2 messaging). This will + also be the default for the volumes . + Defaults to MAC_ROMAN. + + + + + unix charset = CHARSET + (G) + + + Specifies the servers unix charset, e.g. + ISO-8859-15 or EUC-JP. + This is used to convert strings to/from the systems locale, e.g. + for authentication, server messages and volume names. If + LOCALE is set, the systems locale is used. + Defaults to UTF8. + + + + + vol charset = CHARSET + (G)/(V) + + + Specifies the encoding of the volumes filesystem. By + default, it is the same as . + + + + + + + Password Options + + + + passwd file = path + (G) + + + Sets the path to the Randnum UAM passwd file for this server + (default is @pkgconfdir@/afppasswd). + + + + + passwd minlen = number + (G) + + + Sets the minimum password length, if supported by the + UAM + + + + + + + Network Options + + + + advertise ssh = BOOLEAN (default: + no) (G) + + + Allows old Mac OS X clients (10.3.3-10.4) to automagically + establish a tunneled AFP connection through SSH. If this option is + set, the server's answers to client's FPGetSrvrInfo requests + contain an additional entry. It depends on both client's settings + and a correctly configured and running + sshd + + 8 + on the server to let things work. + + + Setting this option is not recommended since globally + encrypting AFP connections via SSH will increase the server's + load significantly. On the other hand, Apple's client side + implementation of this feature in MacOS X versions prior to + 10.3.4 contained a security flaw. + + + + + + afp interfaces = name [name ...] + (G) + + Specifies the network interfaces that the server should + listens on. The default is advertise the first IP address of the + system, but to listen for any incoming request. + + + + + afp listen = ip address[:port] [ip address[:port] + ...] (G) + + + Specifies the IP address that the server should advertise + and listens to. The default is + advertise the first IP address of the system, but to listen for + any incoming request. The network address may be specified either + in dotted-decimal format for IPv4 or in hexadecimal format for + IPv6. + IPv6 address + port combination must use URL the format + using square brackets [IPv6]:port + + + + + afp port = port number + (G) + + + Allows a different TCP port to be used for AFP.

The CNID + Databases are by default located in the + @localstatedir@/netatalk/CNID/(volumename)/.AppleDB/ + directory. + + + + cdb + + + "Concurrent database", backend is based on Oracle Berkley DB. + With this backend several afpd daemons access the + CNID database directly. Berkeley DB locking is used to synchronize + access, if more than one afpd process is active + for a volume. The drawback is, that the crash of a single + afpd process might corrupt the database. + + + + + dbd + + + Access to the CNID database is restricted to the + cnid_metad daemon process. + afpd processes communicate with the daemon for + database reads and updates. If built with Berkeley DB transactions + the probability for database corruption is practically zero, but + performance can be slower than with + + + + + last + + + This backend is an exception, in terms of ID persistency.

Previous AFP/OS versions used codepages, like MacRoman, + MacCentralEurope, etc. + + afpd needs a way to preserve extended Macintosh + characters, or characters illegal in unix filenames, when saving files on + a unix filesystem. Earlier versions used the the so called CAP encoding. + An extended character (>0x7F) would be converted to a :xx sequence, + e.g. the Apple Logo (MacRoman: 0xF0) was saved as :f0. + Some special characters will be converted as to :xx notation as well. + '/' will be encoded to :2f, if + is not specified, a leading dot + '.' will be encoded as :2e. + + This version now uses UTF-8 as the default encoding for names. + '/' will be converted to ':'. + + The option will allow you to select + another volume encoding. E.g. for western users another useful setting + could be vol charset ISO-8859-15. afpd will accept any + + iconv + + 1 + provided charset. If a character cannot be converted + from the to the selected , afpd will save it as a CAP encoded character. For AFP3 + clients, afpd will convert the UTF-8 + UTF8 + + afpd's vol charset setting + + UTF8-MAC + + afpd's vol charset setting + + ISO-8859-15 + + afpd's vol charset setting + + ISO-8859-1 + + afpd's vol charset setting + character to first. If this + conversion fails, you'll receive a -50 error on the mac. + + Note: Whenever you can, please stick with the + default UTF-8 volume format. + + + + SEE ALSO + + + afpd + + 8 + , + afppasswd + + 5 + , + afp_signature.conf + + 5 + , + extmap.conf + + 5 + , + cnid_metad + + 8 + + + diff --git a/doc/manpages/man5/afp_signature.conf.5.xml b/doc/manpages/man5/afp_signature.conf.5.xml new file mode 100644 index 0000000..287b6d7 --- /dev/null +++ b/doc/manpages/man5/afp_signature.conf.5.xml @@ -0,0 +1,87 @@ + + + + + afp_signature.conf + + 5 + + 23 Mar 2012 + + @NETATALK_VERSION@ + + + + afp_signature.conf + + Configuration file used by afpd(8) to specify server + signature + afp_signature.conf + + + + + Description + + @localstatedir@/netatalk/afp_signature.conf is the + configuration file used by afpd to specify + server signature automagically.

CNIDs are a component of + Macintosh based file systems with semantics that map not easily onto Unix + file systems. This makes separate storage in a database necessary. + cnid_dbd is part of the CNID + backend framework of afpd and + implements the dbd backend. + + cnid_dbd is never started via the command line or + system startup scripts but only by the cnid_metad daemon. There is one instance of + cnid_dbd per netatalk volume. + + cnid_dbd uses the Berkeley + DB database library and uses transactionally protected updates. + The dbd backend with transactions will + avoid corruption of the CNID database even if the system crashes + unexpectedly. + + cnid_dbd inherits the effective userid and + groupid from cnid_metad on startup, which + is normally caused by afpd serving a + netatalk volume to a client. It changes to the Berkeley DB database home directory dbdir that is associated with the volume. If the + userid inherited from cnid_metad is 0 + (root), cnid_dbd will change userid and groupid to the + owner and group of the database home directory. Otherwise, it will + continue to use the inherited values. cnid_dbd will + then attempt to open the database and start serving requests using + filedescriptor clntfd. Subsequent instances + of afpd that want to access the same volume + are redirected to the running cnid_dbd process by + cnid_metad via the filedescriptor ctrlfd. + + cnid_dbd can be configured to run forever or to + exit after a period of inactivity. If cnid_dbd receives + a TERM or an INT signal it will exit cleanly after flushing dirty database + buffers to disk and closing Berkeley DB + database environments. It is safe to terminate cnid_dbd + this way, it will be restarted when necessary. Other signals are not + handled and will cause an immediate exit, possibly leaving the CNID + database in an inconsistent state (no transactions) or losing recent + updates during recovery (transactions). + + The Berkeley DB database subsystem + will create files named log.xxxxxxxxxx in the database home directory + dbdir, where xxxxxxxxxx is a monotonically + increasing integer. These files contain the transactional database + changes. They will be removed regularly, unless the logfile_autoremove option is specified in the + db_param configuration file (see + below) with a value of 0 (default 1). + + + + OPTIONS + + + + + + + Show version and exit. + + + + + + + CONFIGURATION + + cnid_dbd reads configuration information from the + file db_param in the database directory + dbdir on startup. If the file does not + exist or a parameter is not listed, suitable default values are used. The + format for a single parameter is the parameter name, followed by one or + more spaces, followed by the parameter value, followed by a newline. The + following parameters are currently recognized: + + + + logfile_autoremove + + + If set to 0, unused Berkeley DB transactional logfiles + (log.xxxxxxxxxx in the database home directory) are not removed on + startup of cnid_dbd and on a regular basis. + Default: 1. + + + + + cachesize + + + Determines the size of the Berkeley DB cache in kilobytes. + Default: 8192. Each cnid_dbd process grabs that + much memory on top of its normal memory footprint. It can be used to + tune database performance. The db_stat utility with the + option that comes with Berkley DB can help you determine ether you + need to change this value. The default is pretty conservative so + that a large percentage of requests should be satisfied from the + cache directly. If memory is not a bottleneck on your system you + might want to leave it at that value. The Berkeley DB Tutorial and Reference Guide has a + section Selecting a cache size that + gives more detailed information. + + + + + flush_frequency + + flush_interval + + + flush_frequency (Default: 1000) + and flush_interval (Default: 1800) + control how often changes to the database are checkpointed. Both of + these operations are performed if either i) more than flush_frequency requests have been received or + ii) more than flush_interval seconds + have elapsed since the last save/checkpoint. Be careful to check + your harddisk configuration for on disk cache settings. Many IDE + disks just cache writes as the default behaviour, so even flushing + database files to disk will not have the desired effect. + + + + + fd_table_size + + + is the maximum number of connections (filedescriptors) that + can be open for afpd client processes + in cnid_dbd. Default: 512. If this + number is exceeded, one of the existing connections is closed and + reused. The affected afpd process + will transparently reconnect later, which causes slight overhead. On + the other hand, setting this parameter too high could affect + performance in cnid_dbd since all descriptors + have to be checked in a select() system call, + or worse, you might exceed the per process limit of open file + descriptors on your system. It is safe to set the value to 1 on + volumes where only one afpd client + process is expected to run, e.g. home directories. + + + + + idle_timeout + + + is the number of seconds of inactivity before an idle + cnid_dbd exits. Default: 600.

The protocol has evolved over the years. The + latest changes to the protocol, called "AFP 3.3", were added with the + release of Snow Leopard + Snow Leopard + + Mac OS X 10.6 + (Mac OS X 10.6). + + The afpd daemon offers the fileservices to Apple clients. The only + configuration file is afp.conf. It uses a ini style + configuration syntax. + + Support for Spotlight + Spotlight + has been added in Netatalk 3.1. See this section for information on how to + compile Netatalk with Spotlight support. + + Mac OS X 10.5 (Leopard) added support for Time Machine backups + over AFP. Two new functions ensure that backups are written to spinning + disk, not just in the server's cache. Different host operating systems + honour this cache flushing differently. To make a volume a Time Machine + target use the volume option "". + + Starting with Netatalk 2.1 UNIX symlinks + symlink + + UNIX symlink + can be used on the server. Semantics are the same as for + eg NFS, ie they are not resolved on the server side but instead it's + completely up to the client to resolve them, resulting in links that + point somewhere inside the clients filesystem view. + + + afp.conf + + afp.conf is the configuration file used by + afpd to determine the behaviour and configuration of the AFP file + serverand the AFP volume that it provides. + + The afp.conf is divided into several + sections: + + [Global] + + + The global section defines general server options + + + + + [Homes] + + + The homes section defines user home volumes + + + Any section not called or + is interpreted as an AFP volume. + + For sharing user homes by defining a + section you must specify the option + which can be a simple string with the path to the parent directory of + all user homes or a regular expression. + + Example: + + [Homes] +basedir regex = /home + + + Now any user logging into the AFP server will have a user volume + available whos path is /home/NAME. + + A more complex setup would be a server with a large amount of + user homes which are split across eg two different + filesystems: + + /RAID1/homes + + + + /RAID2/morehomes + + The following configuration is + required:[Homes] +basedir regex = /RAID./.*homes + + + If contains symlink, set the + canonicalized absolute path. When /home links to + /usr/home: [Homes] +basedir regex = /usr/home + + For a more detailed explanation of the available options, please + refer to the + afp.conf + + 5 + man page. + + + + + CNID<indexterm> + <primary>CNID</primary> + + <secondary>Catalog Node ID</secondary> + </indexterm> backends<indexterm> + <primary>Backend</primary> + + <secondary>CNID backend</secondary> + </indexterm> + + Unlike other protocols like SMB or NFS, the AFP protocol mostly + refers to files and directories by ID and not by a path (the IDs are + also called CNID, that means Catalog Node ID). A typical AFP request + uses a directory ID + DID + + Directory ID + and a filename, something like "server, please + open the file named 'Test' in the directory with id 167". For + example "Aliases" on the Mac basically work by ID (with a fallback to + the absolute path in more recent AFP clients. But this applies only to + Finder, not to applications). + + Every file in an AFP volume has to have a unique file ID + FID + + File ID + , IDs must, according to the specs, never be reused, and + IDs are 32 bit numbers (Directory IDs use the same ID pool). So, after + ~4 billion files/folders have been written to an AFP volume, the ID pool + is depleted and no new file can be written to the volume. No whining + please :-) + + Netatalk needs to map IDs to files and folders in the host + filesystem. To achieve this, several different CNID backends + CNID backend + are available and can be choosed by the + cnidscheme + + specifying a CNID backend + option in the + afp.conf + + 5 + configuration file. A CNID backend is basically a + database storing ID <-> name mappings. + + The CNID Databases are by default located in + /var/netatalk/CNID. + + There is a command line utility called dbd + available which can be used to verify, repair and rebuild the CNID + database. + + + There are some CNID related things you should keep in mind when + working with netatalk: + + + + Don't nest volumes + Nested volumes + . + + + + CNID backends are databases, so they turn afpd into a file + server/database mix. + + + + If there's no more space on the filesystem left, the + database will get corrupted. You can work around this by either + using the option and put the database + files into another location or, if you use quotas, make sure the + CNID database folder is owned by a user/group without a + quota + Quotas + + Disk usage quotas + . + + + + Be careful with CNID databases for volumes that are mounted + via NFS. That is a pretty audacious decision to make anyway, but + putting a database there as well is really asking for trouble, + i.e. database corruption. Use the + directive to put the databases onto a local disk if you must use + NFS + NFS + + Network File System + mounted volumes. + + + + + + cdb<indexterm> + <primary>CDB</primary> + + <secondary>"cdb" CNID backend</secondary> + </indexterm> + + The "concurrent database" backend is based on Berkeley DB. With + this backend, several afpd daemons access the CNID database directly. + Berkeley DB locking is used to synchronize access, if more than one + afpd process is active for a volume. The drawback is, that the crash + of a single afpd process might corrupt the database. cdb should only + be used when sharing home directories for a larger number of users + and it has been determined that a large number of + cnid_dbd processes is problematic. + + + + dbd<indexterm> + <primary>DBD</primary> + + <secondary>"dbd" CNID backend</secondary> + </indexterm> + + Access to the CNID database is restricted to the cnid_dbd daemon + process. afpd processes communicate with the daemon for database reads + and updates. The probability for database corruption is practically + zero. + + This is the default backend since Netatalk 2.1. + + + + tdb<indexterm> + <primary>tdb</primary> + + <secondary>"tdb" CNID backend</secondary> + </indexterm> + + tdb is another persistent CNID database, it's + Samba's Trivial Database. It could be used + instead of cdb for user volumes. + Only ever use it for volumes that are + not shared and accessed by multiple clients + at once ! + This backend is also used internally (as in-memory CNID + database) as a fallback in case opening the primary database can't be + opened, because tdb can work as in-memory database. + This of course means upon restart the CNIDs are gone. + + + + last<indexterm> + <primary>Last</primary> + + <secondary>"last" CNID backend</secondary> + </indexterm> + + The last backend is a in-memory tdb database. It is not + persistent. Starting with netatalk 3.0, it becomes the read + only mode automatically. This is useful e.g. for + CD-ROMs. + + + + mysql<indexterm> + <primary>MySQL</primary> + + <secondary>"mysql" CNID backend</secondary> + </indexterm> + + CNID backend using a MySQL server. + + + + + Charsets<indexterm> + <primary>Charset</primary> + + <secondary>character set</secondary> + </indexterm>/Unicode<indexterm> + <primary>Unicode</primary> + </indexterm> + + + + + Why Unicode? + + Internally, computers don't know anything about characters and + texts, they only know numbers. Therefore, each letter is assigned a + number. A character set, often referred to as + charset or + codepage + Codepage + , defines the mappings between numbers and + letters. + + If two or more computer systems need to communicate with each + other, the have to use the same character set. In the 1960s the + ASCII + ASCII + + American Standard Code for Information + Interchange + (American Standard Code for Information Interchange) + character set was defined by the American Standards Association. The + original form of ASCII represented 128 characters, more than enough to + cover the English alphabet and numerals. Up to date, ASCII has been + the normative character scheme used by computers. + + Later versions defined 256 characters to produce a more + international fluency and to include some slightly esoteric graphical + characters. Using this mode of encoding each character takes exactly + one byte. Obviously, 256 characters still wasn't enough to map all the + characters used in the various languages into one character + set. + + As a result localized character sets were defined later, e.g the + ISO-8859 character sets. Most operating system vendors introduced + their own characters sets to satisfy their needs, e.g. IBM defined the + codepage 437 (DOSLatinUS), Apple introduced the + MacRoman + MacRoman + + MacRoman charset + codepage and so on. The characters that were assigned + number larger than 127 were referred to as + extended characters. These character sets + conflict with another, as they use the same number for different + characters, or vice versa. + + Almost all of those characters sets defined 256 characters, + where the first 128 (0-127) character mappings are identical to ASCII. + As a result, communication between systems using different codepages + was effectively limited to the ASCII charset. + + To solve this problem new, larger character sets were defined. + To make room for more character mappings, these character sets use at + least 2 bytes to store a character. They are therefore referred to as + multibyte character sets. + + One standardized multibyte charset encoding scheme is known as + unicode. A big advantage + of using a multibyte charset is that you only need one. There is no + need to make sure two computers use the same charset when they are + communicating. + + + + character sets used by Apple + + In the past, Apple clients used single-byte charsets to + communicate over the network. Over the years Apple defined a number of + codepages, western users will most likely be using the + MacRoman codepage. + + Codepages defined by Apple include: + + + + MacArabic, MacFarsi + + + + MacCentralEurope + + + + MacChineseSimple + + + + MacChineseTraditional + + + + MacCroation + + + + MacCyrillic + + + + MacDevanagari + + + + MacGreek + + + + MacHebrew + + + + MacIcelandic + + + + MacJapanese + + + + MacKorean + + + + MacRoman + + + + MacRomanian + + + + MacThai + + + + MacTurkish + + + + Starting with Mac OS X and AFP3, UTF-8 is used. UTF-8 encodes + Unicode characters in an ASCII compatible way, each Unicode character + is encoded into 1-6 ASCII characters. UTF-8 is therefore not really a + charset itself, it's an encoding of the Unicode charset. + + To complicate things, Unicode defines several normalization + forms. While samba + Samba + uses precomposed + Precomposed + + Precomposed Unicode normalization + Unicode, which most Unix tools prefer as well, Apple + decided to use the decomposed + Decomposed + + Decomposed Unicode normalization + normalization. + + For example lets take the German character + 'ä'. Using the precomposed normalization, Unicode + maps this character to 0xE4. In decomposed normalization, 'ä' is + actually mapped to two characters, 0x61 and 0x308. 0x61 is the mapping + for an 'a', 0x308 is the mapping for a COMBINING + DIAERESIS. + + Netatalk refers to precomposed UTF-8 as + UTF8 + UTF8 + + Netatalk's precomposed UTF-8 encoding + and to decomposed UTF-8 as + UTF8-MAC + UTF8-MAC + + Netatalk's decomposed UTF-8 encoding + . + + + + afpd and character sets + + To support new AFP 3.x and older AFP 2.x clients at the same + time, afpd needs to be able to convert between the various charsets + used. AFP 3.x clients always use UTF8-MAC, AFP 2.x clients use one of + the Apple codepages. + + At the time of this writing, netatalk supports the following + Apple codepages: + + + + MAC_CENTRALEUROPE + + + + MAC_CHINESE_SIMP + + + + MAC_CHINESE_TRAD + + + + MAC_CYRILLIC + + + + MAC_GREEK + + + + MAC_HEBREW + + + + MAC_JAPANESE + + + + MAC_KOREAN + + + + MAC_ROMAN + + + + MAC_TURKISH + + + + afpd handles three different character set options: + + + + unix charset + unix charset + + afpd's unix charset setting + + + + This is the codepage used internally by your operating + system. If not specified, it defaults to . + If is specified and your system support + Unix locales, afpd tries to detect the codepage. afpd uses this + codepage to read its configuration files, so you can use + extended characters for volume names, login messages, etc. see + + afp.conf + + 5 + . + + + + + mac charset + mac charset + + afpd's mac charset setting + + + + As already mentioned, older Mac OS clients (up to AFP 2.2) + use codepages to communicate with afpd. However, there is no + support for negotiating the codepage used by the client in the + AFP protocol. If not specified otherwise, afpd assumes the + MacRoman codepage is used. In case you're + clients use another codepage, e.g. + MacCyrillic, you'll have to explicitly configure this. see + + afp.conf + + 5 + . + + + + + vol charset + vol charset + + afpd's vol charset setting + + + + This defines the charset afpd should use for filenames on + disk. By default, it is the same as . If you have iconv + Iconv + + iconv encoding conversion engine + installed, you can use any iconv provided charset + as well. + + afpd needs a way to preserve extended macintosh + characters, or characters illegal in unix filenames, when saving + files on a unix filesystem. Earlier versions used the the so + called CAP encoding + CAP encoding + + CAP style character encoding + . An extended character (>0x7F) would be + converted to a :xx hex sequence, e.g. the Apple Logo (MacRoman: + 0xF0) was saved as :f0. Some special characters will be + converted as to :xx notation as well. '/' will be encoded to + :2f, if was not specified, a leading + dot '.' will be encoded as :2e. + + Even though this version now uses as + the default encoding for filenames, '/' will be converted to + ':'. For western users another useful setting could be + . + + If a character cannot be converted from the to the selected , + afpd will save it as a CAP encoded character. For AFP3 clients, + afpd will convert the UTF8 character to first. If this conversion fails, you'll receive + a -50 error on the mac. Note: Whenever you + can, please stick with the default UTF8 volume format. see + + afp.conf + + 5 + . + + + + + + + + Authentication<indexterm> + <primary>Authentication</primary> + + <secondary>between AFP client and server</secondary> + </indexterm> + + + AFP authentication basics + + Apple chose a flexible model called "User Authentication + Modules" + UAM + + User Authentication Module + (UAMs) for authentication purposes between AFP client + and server.

Client-side support is + also necessary. For older Macintoshes running Mac OS < X DHCAST128 + support exists since AppleShare client 3.8.x. + + On OS X, there exist some client-side techniques to make the + AFP-client more verbose, so one can have a look what's happening while + negotiating the UAMs to use. Compare with this hint. + + + + Which UAMs to activate? + + It depends primarily on your needs and on the kind of Mac OS + versions you have to support. Basically one should try to use + DHCAST128 and DHX2 where possible because of its strength of password + encryption. + + + + Unless you really have to supply guest access to your + server's volumes ensure that you disable "No User Authent" since + it might lead accidentally to unauthorized access. In case you + must enable guest access take care that you enforce this on a per + volume base using the access controls. + + + + The "ClearTxt Passwrd" UAM is as bad as it sounds since + passwords go unencrypted over the wire.

Note: If you want to + provide Mac OS 8/9 clients with NetBoot-services then you need + uams_cleartext.so since the AFP-client integrated into the Mac's + firmware can only deal with this basic form of + authentication. + + + + Since "Randnum exchange"/"2-Way Randnum exchange" uses only + 56 bit DES for encryption it should be avoided as well. Another + disadvantage is the fact that the passwords have to be stored in + cleartext on the server and that it doesn't integrate into both + PAM scenarios or classic /etc/shadow (you have to administrate + passwords separately by using the + afppasswd + + 1 + utility, if clients should use these + UAMs) + + + + "DHCAST128" or "DHX2" should be a good compromise for most + people since it combines stronger encryption with PAM + integration. + + + + Using the Kerberos V + Kerberos V + + "Client Krb v2" UAM + ("Client Krb v2") UAM, it's possible to implement + real single sign on scenarios using Kerberos tickets.

The + encrypted portion of the service ticket is sent to the server and + used to authenticate the user.

+ + * Have a look at this Kerberos + overview + + + + SSH tunneling + + Tunneling and all sort of VPN stuff has nothing to do with AFP + authentication and UAMs in general. But since Apple introduced an + option called "Allow Secure Connections Using SSH" and many people + tend to confuse both things, we'll speak about that here too. + + + Manually tunneling an AFP session + + This works since the first AFP servers that spoke "AFP over + TCP" appeared in networks. One simply tunnels the remote server's + AFP port to a local port different than 548 and connects locally to + this port afterwards. On OS X this can be done by + + ssh -l $USER $SERVER -L 10548:127.0.0.1:548 sleep 3000 + + After establishing the tunnel one will use + "afp://127.0.0.1:10548" in the "Connect to + server" dialog. All AFP traffic including the initial connection + attempts will be sent encrypted over the wire since the local AFP + client will connect to the Mac's local port 10548 which will be + forwarded to the remote server's AFP port (we used the default 548) + over SSH. + + These sorts of tunnels are an ideal solution if you've to + access an AFP server providing weak authentications mechanisms + through the Internet without having the ability to use a "real" VPN. + Note that you can let ssh compress the data by + using its "-C" switch and that the tunnel endpoints can be different + from both AFP client and server (compare with the SSH documentation + for details). + + + + Automatically establishing a tunneled AFP connection + + From Mac OS X 10.2 to 10.4, Apple added an "Allow Secure + Connections Using SSH" checkbox to the "Connect to Server" dialog. + The idea behind: When the server signals that it can be contacted by + SSH then Mac OS X' AFP client tries to establish the tunnel and + automagically sends all AFP traffic through it. + + But it took until the release of Mac OS X 10.3 that this + feature worked the first time... partly. In case, the SSH tunnel + can't be established the AFP client silently fell back to an unencrypted AFP + connection attempt. + + Netatalk's afpd will report that it is capable of handling SSH + tunneled AFP requests, when both "" + and "" options are set in + section (double check with + asip-status.pl + + 1 + after you restarted afpd when you made changes to + the settings). But there are a couple of reasons why you don't want + to use this option at all: + + + + Tunneling TCP over TCP (as SSH does) is not the best idea. + There exist better solutions like VPNs based on the IP + layer. + + + + Since this SSH kludge isn't a normal UAM that integrates + directly into the AFP authentication mechanisms but instead uses + a single flag signalling clients whether they can try to establish a tunnel or not, it + makes life harder to see what's happening when things go + wrong. + + + + You cannot control which machines are logged on by + Netatalk tools like a macusers since all + connection attempts seem to be made from localhost. + + + + On the other side you've to limit access to afpd to + localhost only (TCP wrappers) when you want to ensure that all + AFP sessions are SSH encrypted or... + + + + ...when you're using 10.2 - 10.3.3 then you get the + opposite of what you'd expect: potentially unencrypted AFP + communication (including logon credentials) on the network + without a single notification that establishing the tunnel + failed. Apple fixed that not until Mac OS X 10.3.4. + + + + Encrypting all AFP sessions via SSH can lead to a + significantly higher load on the Netatalk server + + + + + + + + ACL Support<indexterm> + <primary>ACLs</primary> + </indexterm> + + ACL support for AFP is implemented for ZFS ACLs on Solaris and + derived platforms and for POSIX 1e ACLs on Linux. + + + Configuration + + For a basic mode of operation there's nothing to configure. + Netatalk reads ACLs on the fly and calculates effective permissions + which are then send to the AFP client via the so called + UARights + UARights + permission bits. On a Mac, the Finder uses these bits + to adjust permission in Finder windows. For example folder whos UNIX + mode would only result in in read-only permissions for a user will not + be displayed with a read-only icon and the user will be able to write + to the folder given the folder has an ACL giving the user write + access. + + By default, the effective permission of the authenticated user + are only mapped to the mentioned UARights + UARights + permission structure, not the UNIX mode. You can adjust + this behaviour with the configuration option map acls. + + However, neither in Finder "Get Info" windows nor in Terminal + will you be able to see the ACLs, that's a result of how ACLs in OS X + are designed. If you want to be able to display ACLs on the client, + things get more involved as you must then setup both client and server + to be part on a authentication domain (directory service, eg LDAP, + OpenDirectory). The reason is, that in OS X ACLs are bound to UUIDs, + not just uid's or gid's. Therefor afpd must be able to map every + filesystem uid and gid to a UUID so that it can return the server side + ACLs which are bound to UNIX uid and gid mapped to OS X UUIDs. + + Netatalk can query a directory server using LDAP queries. Either + the directory server already provides an UUID attribute for user and + groups (Active Directory, Open Directory) or you reuse an unused + attribute (or add a new one) to you directory server (eg + OpenLDAP). + + In detail: + + + + For Solaris/ZFS: ZFS Volumes + + You should configure a ZFS ACL know for any volume you want + to use with Netatalk: + + aclinherit = passthrough +aclmode = passthrough + + For an explanation of what this knob does and how to apply + it, check your hosts ZFS documentation (eg man zfs). + + + + Authentication Domain + + Your server and the clients must be part of a security + association where identity data is coming from a common source. + ACLs in Darwin are based on UUIDs and so is the ACL specification + in AFP 3.2. Therefor your source of identity data has to provide + an attribute for every user and group where a UUID is stored as a + ASCII string. In other words: + + + + you need an Open Directory Server or an LDAP server + where you store UUIDs in some attribute + + + + your clients must be configured to use this + server + + + + your server should be configured to use this server via + nsswitch and PAM + + + + configure Netatalk via the special LDAP options for ACLs in afp.conf so that Netatalk is able + to retrieve the UUID for users and groups via LDAP search + queries + + + + + + + + OS X ACLs + + With Access Control Lists (ACLs) Mac OS X offers a powerful + extension of the traditional UNIX permissions model. An ACL is an + ordered list of Access Control Entries (ACEs) explicitly granting or + denying a set of permissions to a given user or group. + + Unlike UNIX permissions, which are bound to user or group IDs, + ACLs are tied to UUIDs. For this reason accessing an object's ACL + requires server and client to use a common directory service which + translates between UUIDs and user/group IDs. + + ACLs and UNIX permissions interact in a rather simple way. As + ACLs are optional UNIX permissions act as a default mechanism for + access control. Changing an objects's UNIX permissions will leave it's + ACL intact and modifying an ACL will never change the object's UNIX + permissions. While doing access checks, OS X first examines an + object's ACL evaluating ACEs in order until all requested rights have + been granted, a requested right has been explicitly denied by an ACE + or the end of the list has been reached. In case there is no ACL or + the permissions granted by the ACL are not sufficient to fulfill the + request, OS X next evaluates the object's UNIX permissions. Therefore + ACLs always have precedence over UNIX permissions. + + + + ZFS ACLs + + ZFS ACLs closely match OS X ACLs. Both offer mostly identical + fine grained permissions and inheritance settings. + + + + POSIX ACLs + + + Overview + + Compared to OS X or NFSv4 ACLs, Posix ACLs represent a + different, less versatile approach to overcome the limitations of + the traditional UNIX permissions. Implementations are based on the + withdrawn Posix 1003.1e standard. + + The standard defines two types of ACLs. Files and directories + can have access ACLs which are consulted for access checks. + Directories can also have default ACLs irrelevant to access checks. + When a new object is created inside a directory with a default ACL, + the default ACL is applied to the new object as it's access ACL. + Subdirectories inherit default ACLs from their parent. There are no + further mechanisms of inheritance control. + + Architectural differences between Posix ACLs and OS X ACLs + especially involve: + + + + No fine-granular permissions model. Like UNIX + permissions Posix ACLs only differentiate between read, write + and execute permissions. + + + + Entries within an ACL are unordered. + + + + Posix ACLs can only grant rights. There is no way to + explicitly deny rights by an entry. + + + + UNIX permissions are integrated into an ACL as special + entries. + + + + Posix 1003.1e defines 6 different types of ACL entries. The + first three types are used to integrate standard UNIX permissions. + They form a minimal ACL, their presence is mandatory and only one + entry of each type is allowed within an ACL. + + + + ACL_USER_OBJ: the owner's access rights. + + + + ACL_GROUP_OBJ: the owning group's access rights. + + + + ACL_OTHER: everybody's access rights. + + + + The remaining entry types expand the traditional permissions + model: + + + + ACL_USER: grants access rights to a certain user. + + + + ACL_GROUP: grants access rights to a certain + group. + + + + ACL_MASK: limits the maximum access rights which can be + granted by entries of type ACL_GROUP_OBJ, ACL_USER and + ACL_GROUP. As the name suggests, this entry acts as a mask. + Only one ACL_MASK entry is allowed per ACL. If an ACL contains + ACL_USER or ACL_GROUP entries, an ACL_MASK entry must be + present too, otherwise it is optional. + + + + In order to maintain compatibility with applications not aware + of ACLs, Posix 1003.1e changes the semantics of system calls and + utilities which retrieve or manipulate an objects UNIX permissions. + In case an object only has a minimal ACL, the group permissions bits + of the UNIX permissions correspond to the value of the ACL_GROUP_OBJ + entry. + + However, if the ACL also contains an ACL_MASK entry, the + behavior of those system calls and utilities is different. The group + permissions bits of the UNIX permissions correspond to the value of + the ACL_MASK entry, i. e. calling "chmod g-w" will not only revoke + write access for the group, but for all entities which have been + granted write access by ACL_USER or ACL_GROUP entries. + + + + Mapping POSIX ACLs to OS X ACLs + + When a client wants to read an object's ACL, afpd maps it's + Posix ACL onto an equivalent OS X ACL. Writing an object's ACL + requires afpd to map an OS X ACL onto a Posix ACL. Due to + architectural restrictions of Posix ACLs, it is usually impossible + to find an exact mapping so that the result of the mapping process + will be an approximation of the original ACL's semantic. + + + + afpd silently discard entries which deny a set of + permissions because they they can't be represented within the + Posix architecture. + + + + As entries within Posix ACLs are unordered, it is + impossible to preserve order. + + + + Inheritance control is subject to severe limitations as + well: + + Entries with the only_inherit flag set will only + become part of the directory's default ACL. + + + + Entries with at least one of the flags + file_inherit, directory_inherit or limit_inherit set, + will become part of the directory's access and default + ACL, but the restrictions they impose on inheritance + will be ignored. + + + + + + The lack of a fine-granular permission model on the + Posix side will normally result in an increase of granted + permissions. + + + + As OS X clients aren't aware of the Posix 1003.1e specific + relationship between UNIX permissions and ACL_MASK, afpd does not + expose this feature to the client to avoid compatibility issues and + handles *unix permissions and ACLs the same way as Apple's reference + implementation of AFP does. When an object's UNIX permissions are + requested, afpd calculates proper group rights and returns the + result together with the owner's and everybody's access rights to + the caller via "permissions" and "ua_permissions" members of the + FPUnixPrivs structure (see Apple Filing Protocol Reference, page + 181). Changing an object's permissions, afpd always updates + ACL_USER_OBJ, ACL_GROUP_OBJ and ACL_OTHERS. If an ACL_MASK entry is + present too, afpd recalculates it's value so that the new group + rights become effective and existing entries of type ACL_USER or + ACL_GROUP stay intact. + + + + + + Filesystem Change Events<indexterm> + <primary>FCE</primary> + </indexterm> + + Netatalk includes a nifty filesystem change event mechanism where + afpd processes notfiy interested listeners about certain filesystem + event by UDP network datagrams. + + For the format of the UDP packets and for an example C application + that demonstrates how to use these in a listener, take a look at the + Netatalk sourcefile bin/misc/fce.c. + + The currently supported FCE events are + + file modification (fmod) + + + + file deletion (fdel) + + + + directory deletion (ddel) + + + + file creation (fcre) + + + + directory deletion (ddel) + + + + For details on the available simple configuration options take a + look at afp.conf. + + + + + Spotlight<indexterm> + <primary>Spotlight</primary> + </indexterm> + + Starting with version 3.1 Netatalk supports Spotlight searching. + Netatalk uses Gnome Tracker as metadata store, + indexer and search engine. + + + Configuration + + You can enable Spotlight and indexing either globally or on a per + volume basis with the option. + + + Once Spotlight is enable for a single volume, all other volumes + for which spotlight is disabled won't be searchable at all. + + + In case the dbus-daemon binary is not installed + at the path /bin/dbus-daemon, you must use the + global option to point to the path, eg for + Solaris with Tracker from OpenCSW: dbus daemon = /opt/csw/bin/dbus-daemon + + + + Limitations and notes + + + + Large filesystems + + Tracker on Linux uses the inotify Kernel filesystem change + event API for tracking filesystem changes.

The main reason for having the cache + * is avoiding recursive walks up the path, querying the CNID database each time, when + * we have to calculate the location of eg directory with CNID 30, which is located in a dir with + * CNID 25, next CNID 20 and then CNID 2 (the volume root as per AFP spec). + * If all these dirs where in the cache, each database look up can be avoided. Additionally there's + * the element "fullpath" in struct dir, which is used to avoid the recursion in any case. Wheneveer + * a struct dir is initialized, the fullpath to the directory is stored there. + * + * In order to speed up the CNID query for files too, which eg happens when a directory is enumerated, + * files are stored too in the dircache. In order to differentiate between files and dirs, we set + * the flag DIRF_ISFILE in struct dir.d_flags for files. + * + * The most frequent codepatch that leads to caching is directory enumeration (cf enumerate.c): + * - if a element is a directory: + * (1) the cache is searched by dircache_search_by_name() + * (2) if it wasn't found a new struct dir is created and cached both from within dir_add() + * - for files the caching happens a little bit down the call chain: + * (3) first getfilparams() is called, which calls + * (4) getmetadata() where the cache is searched with dircache_search_by_name() + * (5) if the element is not found + * (6) get_id() queries the CNID from the database + * (7) then a struct dir is initialized via dir_new() (note the fullpath arg is NULL) + * (8) finally added to the cache with dircache_add() + * (2) of course does contain the steps 6,7 and 8. + * + * The dircache is a LRU cache, whenever it fills up we call dircache_evict internally which removes + * DIRCACHE_FREE_QUANTUM elements from the cache. + * + * There is only one cache for all volumes, so of course we use the volume id in hashing calculations. + * + * In order to avoid cache poisoning, we store the cached entries st_ctime from stat in + * struct dir.ctime_dircache. Later when we search the cache we compare the stored + * value with the result of a fresh stat. If the times differ, we remove the cached + * entry and return "no entry found in cache". + * A elements ctime changes when + * 1) the element is renamed + * (we loose the cached entry here, but it will expire when the cache fills) + * 2) its a directory and an object has been created therein + * 3) the element is deleted and recreated under the same name + * Using ctime leads to cache eviction in case 2) where it wouldn't be necessary, because + * the dir itself (name, CNID, ...) hasn't changed, but there's no other way. + * + * Indexes + * ======= + * + * The maximum dircache size is: + * max(DEFAULT_MAX_DIRCACHE_SIZE, min(size, MAX_POSSIBLE_DIRCACHE_SIZE)). + * It is a hashtable which we use to store "struct dir"s in.

You can take it out completely and it will make no +difference. The routines (macros) in byteorder.h are totally byteorder +independent. The 386 optimsation just takes advantage of the fact that +the x86 processors don't care about alignment, so we don't have to +align ints on int boundaries etc. If there are other processors out +there that aren't alignment sensitive then you could also define +CAREFUL_ALIGNMENT=0 on those processors as well. + +Ok, now to the macros themselves. I'll take a simple example, say we +want to extract a 2 byte integer from a SMB packet and put it into a +type called uint16 that is in the local machines byte order, and you +want to do it with only the assumption that uint16 is _at_least_ 16 +bits long (this last condition is very important for architectures +that don't have any int types that are 2 bytes long) + +You do this: + +#define CVAL(buf,pos) (((unsigned char *)(buf))[pos]) +#define PVAL(buf,pos) ((unsigned)CVAL(buf,pos)) +#define SVAL(buf,pos) (PVAL(buf,pos)|PVAL(buf,(pos)+1)<<8) + +then to extract a uint16 value at offset 25 in a buffer you do this: + +char *buffer = foo_bar(); +uint16 xx = SVAL(buffer,25); + +We are using the byteoder independence of the ANSI C bitshifts to do +the work. A good optimising compiler should turn this into efficient +code, especially if it happens to have the right byteorder :-) + +I know these macros can be made a bit tidier by removing some of the +casts, but you need to look at byteorder.h as a whole to see the +reasoning behind them. byteorder.h defines the following macros: + +SVAL(buf,pos) - extract a 2 byte SMB value +IVAL(buf,pos) - extract a 4 byte SMB value +LVAL(buf,pos) - extract a 8 byte SMB value +SVALS(buf,pos) signed version of SVAL() +IVALS(buf,pos) signed version of IVAL() + +SSVAL(buf,pos,val) -

+ +dev/ino is used to keep track of magically moved files. did/name is +for quick lookups of CNIDs. + +NOTE: the database will append a nul byte to the end of name. in +addition, name should be given as it appears on disk. this allows the +creation of cnid updating/cleaning programs that don't have to deal +with knowing what the particular codepage is. + +here's the ritual: + 1) open a volume. call cnid_open. + 2) every time you need a CNID, call cnid_add(). it will + automatically look for an existing cnid and add a new one + if one isn't already there. you can pass a hint if you + want. the only use this has right now is to enable + consistency between AFP and HFS. in the future, it would + allow people to write conversion utilities that + pre-instantiate a database without needing to re-assign + CNIDs. + 3) if you want to just look for a CNID without automatically + adding one in, you have two choices: + a) cnid_resolve takes a CNID, returns name, and + over-writes the CNID given with the parent DID. this + is good for FPResolveID. + b) cnid_lookup returns a CNID corresponding to the + dev/ino,did/name keys. it will auto-update the catalog + database if there's a discrepancy. + NOTE: cnid_add calls this before adding a new CNID. + 4) when you delete a file or directory, you need to call + cnid_delete with the CNID for that file/directory. + 5) call cnid_close

three mappings: + CNID -> dev/ino and did/name + dev/ino -> CNID + did/name -> CNID + +dev/ino is used to keep track of magically moved files. did/name is +for quick lookups of CNIDs. + +NOTE: the database will append a nul byte to the end of name. in +addition, name should be given as it appears on disk. this allows the +creation of cnid updating/cleaning programs that don't have to deal +with knowing what the particular codepage is. + +here's the ritual: + 1) open a volume. call cnid_open. + 2) every time you need a CNID, call cnid_add(). it will + automatically look for an existing cnid and add a new one + if one isn't already there. you can pass a hint if you + want. the only use this has right now is to enable + consistency between AFP and HFS. in the future, it would + allow people to write conversion utilities that + pre-instantiate a database without needing to re-assign + CNIDs. + 3) if you want to just look for a CNID without automatically + adding one in, you have two choices: + a) cnid_resolve takes a CNID, returns name, and + over-writes the CNID given with the parent DID. this + is good for FPResolveID. + b) cnid_lookup returns a CNID corresponding to the + dev/ino,did/name keys. it will auto-update the catalog + database if there's a discrepancy. + NOTE: cnid_add calls this before adding a new CNID. + 4) when you delete a file or directory, you need to call + cnid_delete with the CNID for that file/directory. + 5) call cnid_close when closing the volume. diff --git a/libatalk/cnid/tdb/cnid_tdb.h b/libatalk/cnid/tdb/cnid_tdb.h new file mode 100644

of many small packets. as a consequence, i +use TCP_NODELAY to speed up the turnaround time. + +because dsi_read can send incomplete packets, proto_send should not +use the length parameter to specify the dsi_len field in the +header. instead, anything that uses proto_send needs to specify +dsi_len (in network byte order) before calling proto_send. the +dsi_send() macro already does this. +

(4faeaea) + + + +Changes in 2.0.3-alpha (20 Nov 2009): + o Add a new code to support SSL/TLS on bufferevents, using the OpenSSL library (where available). + o Fix a bug where we didn't allocate enough memory in event_get_supported_methods(). + o Avoid segfault during failed allocation of locked evdns_base. (Found by Rocco Carbone.) + o Export new evutil_ascii_* functions to perform locale-independent character type operations. + o Try to compile better with MSVC: patches from Brodie Thiesfield + o New evconnlistener_get_fd function to expose a listener's associated socket. + o Expose an ev_socklen_t type for consistent use across platforms. + o Make bufferevent_socket_connect() work when the original fd was -1. + o Fix a bug in bufferevent_socket_connect() when the connection succeeds too quickly. + o Export an evutil_sockaddr_cmp() to compare to sockaddr objects for equality. + o Add a bufferevent_get_enabled() to tell what a bufferevent has been configured to do. + o Add an evbuffer_search_eol() function to locate the end of a line nondestructively. + o Add an evbuffer_search_range() function to search a bounded range of a buffer. + o Fix a rare crash bug in evdns. + o Have bufferevent_socket_connect() with no arguments put a bufferevent into connecting mode. + o Support sendfile on Solaris: patch from Caitlin Mercer. + o New functions to explicitly reference a socket used by an evhttp object. Patches from David Reiss. + o When we send a BEV_EVENT_CONNECTED to indicate connected status, we no longer invoke the write callback as well unless we actually wrote data too. + o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov. + o Do not detect whether we have monotonic clock support every time a new event base is created: instead do it only once. Patch taken from Chromium. + o Do not allocate the maximum event queue for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 374K per epoll-based event_base. Resolves bug 2839240. + o Treat an event with a negative fd as valid but untriggerable by Libevent. This is useful for applications that want to manually activate events. + o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h + o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec + o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak(). Patch from Ka-Hing Cheung. + o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. + o Fix some bugs when using the old evdns interfaces to initialize the evdns module. + o Detect errors during bufferevent_connect(). Patch from Christopher Davis. + o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. + o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. + o Fix a bug when using a specialized memory allocator on win32. + o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. + o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. + o Add an API to replace all fatal calls to exit() with a user-provided panic function. + o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. + o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. + o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. + o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. + o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. + o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. + o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. + o New event_base_config option to disable the timeval cache entirely. + o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. + o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. + o Fix a problem with excessive memory allocation when using multiple event priorities. + o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. + o Never check the environment when we're running setuid or setgid; from OpenBSD. + o Options passed to evdns_set_option() no longer need to end with a colon. + o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. + o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. + o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. + o Numerous other bugfixes. + o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. + o Fix a race condition in the pthreads test case; found by Nick Mathewson + o Remove most calls to event_err() in http and deal with memory errors instead + + + +Changes in 2.0.2-alpha (25 Jul 2009): + o Add a new flag to bufferevents to make all callbacks automatically deferred. + o Make evdns functionality locked, and automatically defer dns callbacks. + o Fix a possible free(NULL) when freeing an event_base with no signals. + o Add a flag to disable checking environment varibles when making an event_base + o Disallow setting less than 1 priority. + o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] + o Use signal.h, not sys/signal.h. [Patch from mmadia] + o Try harder to build with certain older c99 compilers. + o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] + o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] + o Make sendfile work on FreeBSD + o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. + o Actually define the event_config_set_flag() function. + o Try harder to compile with Visual C++. + o Move event_set() and its allies to event2/event_compat.h where they belong. + o Remove the event_gotsig code, which has long been deprecated and unused. + o Add an event_get_base() function to return the base assigned to an event. + o New function to automate connecting on a socket-based bufferevent. + o New functions to automate listening for incoming TCP connections. + o Do case-insensitive checks with a locale-independent comparison function. + o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. + o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. + o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h + o Add a bufferevent_getfd() function to mirror bufferevent_setfd() + o Make bufferevent_setfd() return an error code if the operation is not successful. + o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. + o Cap the maximum number of priorities at 256. + o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. + o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information + o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. + o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. + o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) + o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) + o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. + o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). + o Replace some read()/write() instances with send()/recv() to work properly on win32. + o Set truncated flag correctly in evdns server replies. + o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg + o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. + o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. + o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg + o Mitigate a race condition when using socket bufferevents in multiple threads. + o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. + o Do not allow event_del(ev) to return while that event's callback is executing in another thread.

Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb + o Check return value of event_add in signal.c + o provide event_reinit() to reintialize an event_base after fork + o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. + o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. + o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. + o Check return value of event_add in signal.c + o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. + o Do not mangle socket handles on 64-bit windows. + o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings.

Wijngaards + o devpoll and evport need reinit; tested by W.C.A Wijngaards + o event_base_get_method; from Springande Ulv + o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184. + o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values. + o Use a 64-bit field to hold HTTP content-lengths.

This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed. + o Make name_from_addr() threadsafe in http.c + o Add new thread-safe interfaces to evdns functions. + o Make all event_tagging interfaces threadsafe. + o Rename internal memory management functions. + o New functions (event_assign, event_new, event_free) for use by apps that want to be safely threadsafe, or want to remain ignorant of the contents of struct event. + o introduce bufferevent_read_buffer; allows reading without memory copy. + o expose bufferevent_setwatermark via header files and fix high watermark on read + o fix a bug in buffrevent read water marks and add a test for them + o fix a bug in which bufferevent_write_buffer would not schedule a write event + o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure + o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents + o convert evhttp_connection to use bufferevents. + o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy. + o Remove the never-exported, never-used evhttp_hostportfile function. + o Support input/output filters for bufferevents; somewhat similar to libio's model. This will allow us to implement SSL, compression, etc, transparently to users of bufferevents such as the http layer. + o allow connections to be removed from an rpc pool + o add new evtimer_assign, signal_assign, evtimer_new, and signal_new functions to manipulate timer and signal events, analagous to the now-recommended event_assign and event_new + o switch internal uses of event_set over to use event_assign. + o introduce evbuffer_contiguous_space() api that tells a user how much data is available in the first buffer chain + o introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient. + o reduce system calls for getting current time by caching it. + o separate signal events from io events; making the code less complex. + o support for periodic timeouts + o support for virtual HTTP hosts. + o turn event_initialized() into a function, and add function equivalents to EVENT_SIGNAL and EVENT_FD so that people don't need to include event_struct.h + o Build test directory correctly with CPPFLAGS set. + o Provide an API for retrieving the supported event mechanisms. + o event_base_new_with_config() and corresponding config APIs. + o migrate the evhttp header to event2/ but accessors are still missing. + o deprecate timeout_* event functions by moving them to event_compat.h + o Move windows gettimeofday replacement into a new evutil_gettimeofday(). + o Make configure script work on IRIX. + o provide a method for canceling ongoing http requests. + o Make vsnprintf() returns consistent on win32. + o Fix connection keep-alive behavior for HTTP/1.0 + o Fix use of freed memory in event_reinit; pointed out by Peter Postma + o constify struct timeval * where possible + o make event_get_supported_methods obey environment variables + o support for edge-triggered events on epoll and kqueue backends: patch from Valery Kholodkov + o support for selecting event backends by their features, and for querying the features of a backend. + o change failing behavior of event_base_new_with_config: if a config is provided and no backend is selected, return NULL instead of aborting. + o deliver partial data to request callbacks when chunked callback is set even if there is no chunking on the http level; allows cancelation of requests from within the chunked callback; from Scott Lamb. + o allow min_heap_erase to be called on removed members; from liusifan. + o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT.

This helps resist DNS poisoning attacks. + o Make the http connection close detection work properly with bufferevents and fix a potential memory leak associated with it. + o Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. + o Add generic implementations for parsing and emiting IPv6 addresses on platforms that do not have inet_ntop and/or inet_pton. + o Allow DNS servers that have IPv6 addresses. + o Add an evbuffer_write_atmost() function to write a limited number of bytes to an fd. + o Refactor internal notify-main-thread logic to prefer eventfd to pipe, then pipe to socketpair, and only use socketpairs as a last resort. + o Try harder to pack all evbuffer reads into as few chains as possible, using readv/WSARecv as appropriate. + o New evthread_use_windows_threads() and evthread_use_pthreads() functions to set up the evthread callbacks with reasonable defaults. + o Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. + o sendfile, mmap and memory reference support for evbuffers. + o New evutil_make_listen_socket_reuseable() to abstract SO_REUSEADDR. + o New bind-to option to allow DNS clients to bind to an arbitrary port for outgoing requests. + o evbuffers can now be "frozen" to prevent operations at one or both ends. + o Bufferevents now notice external attempts to add data to an inbuf or remove it from an outbuf, and stop them. + o Fix parsing of queries where the encoded queries contained \r, \n or + + o Do not allow internal events to starve lower-priority events. + +Changes in 1.4.0: + o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr. + o demote most http warnings to debug messages + o Fix Solaris compilation; from Magne Mahre + o Add a "Date" header to HTTP responses, as required by HTTP 1.1. + o Support specifying the local address of an evhttp_connection using set_local_address + o Fix a memory leak in which failed HTTP connections whould not free the request object + o Make adding of array members in event_rpcgen more efficient, but doubling memory allocation + o Fix a memory leak in the DNS server + o Fix compilation when DNS_USE_OPENSSL_FOR_ID is enabled + o Fix buffer size and string generation in evdns_resolve_reverse_ipv6(). + o Respond to nonstandard DNS queries with "NOTIMPL" rather than by ignoring them. + o In DNS responses, the CD flag should be preserved, not the TC flag. + o Fix http.c to compile properly with USE_DEBUG; from Christopher Layne + o Handle NULL timeouts correctly on Solaris; from Trond Norbye + o Recalculate pending events properly when reallocating event array on Solaris; from Trond Norbye + o Add Doxygen documentation to header files; from Mark Heily + o Add a evdns_set_transaction_id_fn() function to override the default + transaction ID generation code. + o Add an evutil module (with header evutil.h) to implement our standard cross-platform hacks, on the theory that somebody else would like to use them too. + o Fix signals implementation on windows. + o Fix http module on windows to close sockets properly. + o Make autogen.sh script run correctly on systems where /bin/sh isn't bash. (Patch from Trond Norbye, rewritten by Hagne Mahre and then Hannah Schroeter.) + o Skip calling gettime() in timeout_process if we are not in fact waiting for any events. (Patch from Trond Norbye) + o Make test subdirectory compile under mingw. + o Fix win32 buffer.c behavior so that it is correct for sockets (which do not like ReadFile and WriteFile). + o Make the test.sh script run unit tests for the evpoll method. + o Make the entire evdns.h header enclosed in "extern C" as appropriate. + o Fix implementation of strsep on platforms that lack it + o Fix implementation of getaddrinfo on platforms that lack it; mainly, this will make Windows http.c work better. Original patch by Lubomir Marinov. + o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa + o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication. + o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin + o associate an event base with an rpc pool + o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support + o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. + o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. + o Small code cleanups in epoll_dispatch(). + o Increase the maximum number of addresses read from a packet in evdns to 32. + o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. + o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. + o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. + o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. + o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. + o Remove the long-deprecated acconfig.h file. + o Do not require #include before #include . + o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. + o Fix many build issues when using the Microsoft C compiler. + o Remove a bash-ism in autogen.sh + o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne. + o Make the logic for active events work better with internal events; patch from Christopher Layne. + o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne. diff --git a/libevent/Doxyfile b/libevent/Doxyfile new file mode 100644 index 0000000..5d3865e --- /dev/null +++ b/libevent/Doxyfile @@ -0,0 +1,257 @@ +# Doxyfile 1.5.1 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# The PROJECT_NAME tag is a single word (or a sequence of words surrounded +# by quotes) that should identify the project. + +PROJECT_NAME = libevent + +# Place all output under 'doxygen/' + +OUTPUT_DIRECTORY = doxygen/ + +# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen +# will interpret the first line (until the first dot) of a JavaDoc-style +# comment as the brief description.

As a + result, evbuffers can be used to pass data around without actually + incurring the overhead of copying the data. + + A new evbuffer can be allocated with evbuffer_new(), and can be + freed with evbuffer_free(). Most users will be using evbuffers via + the bufferevent interface. To access a bufferevent's evbuffers, use + bufferevent_get_input() and bufferevent_get_output(). + + There are several guidelines for using evbuffers. + + - if you already know how much data you are going to add as a result + of calling evbuffer_add() multiple times, it makes sense to use + evbuffer_expand() first to make sure that enough memory is allocated + before hand. + + - evbuffer_add_buffer() adds the contents of one buffer to the other + without incurring any unnecessary memory copies. + + - evbuffer_add() and evbuffer_add_buffer() do not mix very well: + if you use them, you will wind up with fragmented memory in your + buffer. + + - For high-performance code, you may want to avoid copying data into and out + of buffers. You can skip the copy step by using + evbuffer_reserve_space()/evbuffer_commit_space() when writing into a + buffer, and evbuffer_peek() when reading. + + In Libevent 2.0 and later, evbuffers are represented using a linked + list of memory chunks, with pointers to the first and last chunk in + the chain. + + As the contents of an evbuffer can be stored in multiple different + memory blocks, it cannot be accessed directly. Instead, evbuffer_pullup() + can be used to force a specified number of bytes to be contiguous. This + will cause memory reallocation and memory copies if the data is split + across multiple blocks. It is more efficient, however, to use + evbuffer_peek() if you don't require that the memory to be contiguous. + */ + +#ifdef __cplusplus +extern "C" { +#endif + +#include +#include +#ifdef _EVENT_HAVE_SYS_TYPES_H +#include +#endif +#ifdef _EVENT_HAVE_SYS_UIO_H +#include +#endif +#include + +/** + An evbuffer is an opaque data type for efficiently buffering data to be + sent or received on the network. + + @see event2/event.h for more information +*/ +struct evbuffer +#ifdef _EVENT_IN_DOXYGEN +{} +#endif +; + +/** + Pointer to a position within an evbuffer. + + Used when repeatedly searching through a buffer.

Before you use this library you should see if libc + * can do the job for you with the modern async call getaddrinfo_a + * (see http://www.imperialviolet.org/page25.html#e498). Otherwise, + * please continue. + * + * The library keeps track of the state of nameservers and will avoid + * them when they go down. Otherwise it will round robin between them. + * + * Quick start guide: + * #include "evdns.h" + * void callback(int result, char type, int count, int ttl, + * void *addresses, void *arg); + * evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + * evdns_resolve("www.hostname.com", 0, callback, NULL); + * + * When the lookup is complete the callback function is called. The + * first argument will be one of the DNS_ERR_* defines in evdns.h. + * Hopefully it will be DNS_ERR_NONE, in which case type will be + * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time + * which the data can be cached for (in seconds), addresses will point + * to an array of uint32_t's and arg will be whatever you passed to + * evdns_resolve. + * + * Searching: + * + * In order for this library to be a good replacement for glibc's resolver it + * supports searching. This involves setting a list of default domains, in + * which names will be queried for. The number of dots in the query name + * determines the order in which this list is used. + * + * Searching appears to be a single lookup from the point of view of the API, + * although many DNS queries may be generated from a single call to + * evdns_resolve. Searching can also drastically slow down the resolution + * of names. + * + * To disable searching: + * 1. Never set it up.

The Libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, Libevent also support callbacks due + to signals or regular timeouts. + + Libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_dispatch() and then add or + remove events dynamically without having to change the event loop. + + + Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2), + epoll(4), and evports. The internal event mechanism is completely + independent of the exposed event API, and a simple update of Libevent can + provide new functionality without having to redesign the applications. As a + result, Libevent allows for portable application development and provides + the most scalable event notification mechanism available on an operating + system. Libevent can also be used for multithreaded programs. Libevent + should compile on Linux, *BSD, Mac OS X, Solaris and, Windows. + + @section usage Standard usage + + Every program that uses Libevent must inclurde the + header, and pass the -levent flag to the linker. (You can instead link + -levent_core if you only want the main event and buffered IO-based code, + and don't want to link any protocol code.) + + @section setup Library setup + + Before you call any other Libevent functions, you need to set up the + library. If you're going to use Libevent from multiple threads in a + multithreaded application, you need to initialize thread support -- + typically by using evthread_use_pthreads() or + evthread_use_windows_threads(). See for more + information. + + This is also the point where you can replace Libevent's memory + management functions with event_set_mem_functions, and enable debug mode + with event_enable_debug_mode(). + + @section base Creating an event base + + Next, you need to create an event_base structure, using event_base_new() + or event_base_new_with_config(). The event_base is responsible for + keeping track of which events are "pending" (that is to say, being + watched to see if they become active) and which events are "active". + Every event is associated with a single event_base. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must create an + event structure with event_new(). (You may also declare an event + structure and call event_assign() to initialize the members of the + structure.) To enable notification, you add the structure to the list + of monitored events by calling event_add(). The event structure must + remain allocated as long as it is active, so it should generally be + allocated on the heap. + + @section loop Dispaching evets. + + Finally, you call event_base_dispatch() to loop and dispatch events. + You can also use event_base_loop() for more fine-grained control. + + Currently, only one thread can be dispatching a given event_base at a + time. If you want to run events in multiple threads at once, you can + either have a single event_base whose events add work to a work queue, + or you can create multiple event_base objects. + + @section bufferevent I/O Buffers + + Libevent provides a buffered I/O abstraction on top of the regular event + callbacks. This abstraction is called a bufferevent. A bufferevent + provides input and output buffers that get filled and drained + automatically. The user of a buffered event no longer deals directly + with the I/O, but instead is reading from input and writing to output + buffers. + + Once initialized via bufferevent_socket_new(), the bufferevent structure + can be used repeatedly with bufferevent_enable() and + bufferevent_disable(). Instead of reading and writing directly to a + socket, you would call bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + See for more information. + + @section timers Timers + + Libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_new() function returns + an event struct to use as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + + @section evdns Asynchronous DNS resolution + + Libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. See the + functions for more detail. + + @section evhttp Event-driven HTTP servers + + Libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the header in your + program. See that header for more information. + + @section evrpc A framework for RPC servers and clients + + Libevent provides a framework for creating RPC servers and clients.

If ACTION-IF-FOUND is not specified, the +# default action will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or +# if you have any other suggestions or comments. This macro was based +# on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) +# (with help from M. Frigo), as well as ac_pthread and hb_pthread +# macros posted by Alejandro Forero Cuervo to the autoconf macro +# repository.
