90 Together C<bisect.pl> and C<bisect-runner.pl> attempt to automate the use
91 of C<git bisect> as much as possible. With one command (and no other files)
98 Which commit caused this example code to break?
102 Which commit caused this example code to start working?
106 Which commit added the first to match this regex?
110 Which commit removed the last to match this regex?
114 usually without needing to know which versions of perl to use as start and
117 By default C<bisect.pl> will process all options, then use the rest of the
118 command line as arguments to list C<system> to run a test case. By default,
119 the test case should pass (exit with 0) on earlier perls, and fail (exit
120 non-zero) on I<blead>. C<bisect.pl> will use C<bisect-runner.pl> to find the
121 earliest stable perl version on which the test case passes, check that it
122 fails on blead, and then use C<bisect-runner.pl> with C<git bisect run> to
123 find the commit which caused the failure.
125 Because the test case is the complete argument to C<system>, it is easy to
126 run something other than the F<perl> built, if necessary. If you need to run
127 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
129 You need a clean checkout to run a bisect, and you can't use the checkout
130 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
131 a revision before F<Porting/bisect-runner.pl> was added, which
132 C<git bisect run> needs). If your working checkout is called F<perl>, the
133 simplest solution is to make a local clone, and run from that. I<i.e.>:
138 ../perl/Porting/bisect.pl ...
146 --start I<commit-ish>
148 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
149 else C<git> understands as a revision). If not specified, C<bisect.pl> will
150 search stable perl releases from 5.002 to 5.14.0 until it finds one where
151 the test case passes.
157 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
164 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
165 this should be one of
173 Just run C<Configure>
179 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
191 Use F<miniperl> to build F<lib/Config.pm>
197 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
198 is simple XS module present since 5.000, this provides a fast test of
199 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
200 hence this target will not build F<perl>.
206 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
207 F<ext>. XS modules (such as L<Fcntl>) are not built.
213 Build everything needed to run the tests. This is the default if we're
214 running test code, but is time consuming, as it means building all
215 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
216 is automatically substituted. For very old F<Makefile>s, C<make test> is
217 run, as there is no target provided to just get things ready, and for 5.004
218 and earlier the tests run very quickly.
224 --one-liner 'code to run'
230 Example code to run, just like you'd use with C<perl -e>.
232 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
233 or C<./miniperl> if I<target> is C<miniperl>.
235 (Usually you'll use C<-e> instead of providing a test case in the
236 non-option arguments to C<bisect.pl>)
238 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
239 which interferes with detecting errors in the example code itself.
245 The test case should fail for the I<start> revision, and pass for the I<end>
246 revision. The bisect run will find the first commit where it passes.
258 -Accflags=-DNO_MATHOMS
260 Arguments to pass to F<Configure>. Repeated C<-A> arguments are passed
261 through as is. C<-D> and C<-U> are processed in order, and override
262 previous settings for the same parameter.
272 Number of C<make> jobs to run in parallel. If F</proc/cpuinfo> exists and can
273 be parsed, or F</sbin/sysctl> exists and reports C<hw.ncpu>, defaults to
274 1 + I<number of CPUs>. Otherwise defaults to 2.
280 Instead of running a test program to determine I<pass> or I<fail>, pass
281 if the given regex matches, and hence search for the commit that removes
282 the last matching file.
284 If no I<target> is specified, the match is against all files in the
285 repository (which is fast). If a I<target> is specified, that target is
286 built, and the match is against only the built files. C<--expect-fail> can
287 be used with C<--match> to search for a commit that adds files that match.
293 Test that the build completes, without running any test case.
295 By default, if the build for the desired I<target> fails to complete,
296 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
297 being that one wants to find a commit which changed state "builds && passes"
298 to "builds && fails". If instead one is interested in which commit broke the
299 build (possibly for particular F<Configure> options), use I<--test-build>
300 to treat a build failure as a failure, not a "skip".
302 Often this option isn't as useful as it first seems, because I<any> build
303 failure will be reported to C<git bisect> as a failure, not just the failure
304 that you're interested in. Generally, to debug a particular problem, it's
305 more useful to use a I<target> that builds properly at the point of interest,
306 and then a test case that runs C<make>. For example:
308 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
309 --expect-fail --force-manifest --target=miniperl make perl
311 will find the first revision capable of building C<DynaLoader> and then
312 C<perl>, without becoming confused by revisions where C<miniperl> won't
319 By default, a build will "skip" if any files listed in F<MANIFEST> are not
320 present. Usually this is useful, as it avoids false-failures. However, there
321 are some long ranges of commits where listed files are missing, which can
322 cause a bisect to abort because all that remain are skipped revisions.
324 In these cases, particularly if the test case uses F<miniperl> and no modules,
325 it may be more useful to force the build to continue, even if files
326 F<MANIFEST> are missing.
332 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
338 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
339 to use F<bisect-runner.pl> to build the current particular perl revision for
340 interactive testing, or for debugging F<bisect-runner.pl>.
342 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
