3. It is relatively expensive to fire off a process to fix a source
file, therefore write apply tests to avoid unnecessary fix
processes. The preferred apply tests are "select", "bypass" and
- "c_test" because they are performed internally. "test" sends
- a command to a server shell that actually fires off one or more
- processes to do the testing. Avoid it, if you can, but it is
- still more efficient than a fix process. Also available is
- "mach". If the target machine matches any of the named
- globbing-style patterns, then the machine name test will pass.
- It is desired, however, to limit the use of this test.
+ "c_test" because they are performed internally. The available
+ tests are:
+
+ * select - Run a regex on the contents of the file being considered.
+ All such regex-es must match.
+
+ * bypass - Run a regex on the contents of the file being considered.
+ No such regex may match.
+
+ * c_test - call a function in fixtests.c. See that file.
+
+ The next two tests are relatively slow because they must be handled
+ in a separate shell process. Some platforms do not support server
+ shells, so the whole process is even slower and more cumbersome there.
+
+ * mach - Match the output of config.conf against a series of globbing
+ patterns. It must match at least one of the patterns, unless
+ "not-machine" has also been specified. If that has been
+ specified, then the config.conf output may not match any of
+ the patterns.
+
+ * test - These should be arguments to the program, "/bin/test".
+ You may perform multiple commands, if you enclose them
+ in backquotes and echo out valid test arguments. For
+ example, you might echo out '0 -eq 1' if you want a false
+ result, or '0 -eq 0' for a true result.
These tests are required to:
rules, except that the backslash is processed before
'\\', '\'' and '#' characters (using C character syntax).
+ Each test must pass or the fix is not applied. For example,
+ all "select" expressions must be found and not one "bypass"
+ selection may be found.
