progress: drop delay-threshold code

Since 180a9f2268 (provide a facility for "delayed" progress

callers to skip showing progress if they have reached a
percentage-threshold of the total work before the delay
period passes.

But since 8aade107dd (progress: simplify "delayed" progress
API, 2017-08-19), that parameter is not available to outside
callers (we always passed zero after that commit, though
that was corrected in the previous commit to "100%").

Let's drop the threshold code, which never triggers in

progress: set default delay threshold to 100%, not 0%

Commit 8aade107dd (progress: simplify "delayed" progress
API, 2017-08-19) dropped the parameter by which callers
could say "show my progress only if I haven't passed M%
progress after N seconds". The intent was to just show
nothing for 2 seconds, and then always progress after that.

But we flipped the logic in the wrapper: it sets M=0,
meaning that we'd almost _never_ show progress after 2
seconds, since we'd generally have made some progress. This
should have been 100%, not 0%.

We were fooled by existing calls like:

  start_progress_delay("foo", 0, 0, 2);

which behaved this way. The trick is that the first "0"
there is "how many items total", and there zero means "we
don't know". And without knowing that, we cannot compute a
completed percent at all, and we ignored the threshold
parameter entirely! Modeling our wrapper after that broke
callers which pass a non-zero value for "total".

We can switch to the intended behavior by using "100" in the
wrapper call.

6 years agosha1_file: use strbuf_add() instead of strbuf_addf()

sha1_file: use strbuf_add() instead of strbuf_addf()

Replace use of strbuf_addf() with strbuf_add() when enumerating
loose objects in for_each_file_in_obj_subdir(). Since we already
check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.

One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.

Most repositories do not have many loose objects before repacking,
but in the GVFS case the repos can grow to have millions of loose
objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().

Add a new performance test to p4211-line-log.sh that is more
sensitive to this cache-loading. By limiting to 1000 commits, we
more closely resemble user wait time when reading history into a
pager.

For a copy of the Linux repo with two ~512 MB packfiles and ~572K

grep: fix segfault under -P + PCRE2 <=10.30 + (*NO_JIT)

Fix a bug in the compilation of PCRE2 patterns under JIT (the most
common runtime configuration). Any pattern with a (*NO_JIT) verb would
segfault in any currently released PCRE2 version:

    $ git grep -P '(*NO_JIT)hi.*there'
    Segmentation fault

That this segfaulted was a bug in PCRE2 itself, after reporting it[1]
on pcre-dev it's been fixed in a yet-to-be-released version of
PCRE (presumably released first as 10.31). Now it'll die with:

    $ git grep -P '(*NO_JIT)hi.*there'
    fatal: pcre2_jit_match failed with error code -45: bad JIT option

But the cause of the bug is in our own code dating back to my
94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).

As explained at more length in the comment being added here, it isn't
sufficient to just check pcre2_config() to see whether the JIT should
be used, pcre2_pattern_info() also has to be asked.

This is something I discovered myself when fiddling around with PCRE2
verbs in patterns passed to git. I don't expect that any user of git
has encountered this given the obscurity of passing PCRE2 verbs
through to the library, along with the relative obscurity of (*NO_JIT)
itself.

test-lib: add LIBPCRE1 & LIBPCRE2 prerequisites

Add LIBPCRE1 and LIBPCRE2 prerequisites which are true when git is
compiled with USE_LIBPCRE1=YesPlease or USE_LIBPCRE2=YesPlease,
respectively.

The syntax of PCRE1 and PCRE2 isn't the same in all cases (see
pcresyntax(3) and pcre2syntax(3)). If test are added that test for
those they'll need to be guarded by these new prerequisites.

The subsequent patch will make use of LIBPCRE2, so LIBPCRE1 isn't
strictly needed for now, but let's add it for consistency and so that
checking for it doesn't have to be done with the less obvious "PCRE,
!LIBPCRE2", which while semantically the same is more confusing, and
would lead to bugs if PCRE v3 is ever released as the tests would mean
v1, not any non-v2 version.

stash: learn to parse -m/--message like commit does

`git stash push -m foo` uses "foo" as the message for the stash. But
`git stash push -m"foo"` does not parse successfully.  Similarly
`git stash push --message="My stash message"` also fails.  The stash
documentation doesn't suggest this syntax should work, but gitcli
does and my fingers have learned this pattern long ago for `commit`.

Teach `git stash` to parse -mFoo and --message=Foo the same as `git
commit` would do.  Even though it's an internal function, add
similar support to create_stash() for consistency.
