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 ...>
135 --start I<commit-ish>
137 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
138 else C<git> understands as a revision). If not specified, C<bisect.pl> will
139 search stable perl releases from 5.002 to 5.14.0 until it finds one where
140 the test case passes.
146 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
153 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
154 this should be one of
162 Just run C<Configure>
168 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
180 Use F<miniperl> to build F<lib/Config.pm>
186 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
187 is simple XS module present since 5.000, this provides a fast test of
188 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
189 hence this target will not build F<perl>.
195 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
196 F<ext>. XS modules (such as L<Fcntl>) are not built.
202 Build everything needed to run the tests. This is the default if we're
203 running test code, but is time consuming, as it means building all
204 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
205 is automatically substituted. For very old F<Makefile>s, C<make test> is
206 run, as there is no target provided to just get things ready, and for 5.004
207 and earlier the tests run very quickly.
213 --one-liner 'code to run'
219 Example code to run, just like you'd use with C<perl -e>.
221 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
222 or C<./miniperl> if I<target> is C<miniperl>.
224 (Usually you'll use C<-e> instead of providing a test case in the
225 non-option arguments to C<bisect.pl>)
227 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
228 which interferes with detecting errors in the example code itself.
234 The test case should fail for the I<start> revision, and pass for the I<end>
235 revision. The bisect run will find the first commit where it passes.
247 -Accflags=-DNO_MATHOMS
249 Arguments to pass to F<Configure>. Repeated C<-A> arguments are passed
250 through as is. C<-D> and C<-U> are processed in order, and override
251 previous settings for the same parameter.
261 Number of C<make> jobs to run in parallel. If F</proc/cpuinfo> exists and can
262 be parsed, or F</sbin/sysctl> exists and reports C<hw.ncpu>, defaults to
263 1 + I<number of CPUs>. Otherwise defaults to 2.
269 Instead of running a test program to determine I<pass> or I<fail>, pass
270 if the given regex matches, and hence search for the commit that removes
271 the last matching file.
273 If no I<target> is specified, the match is against all files in the
274 repository (which is fast). If a I<target> is specified, that target is
275 built, and the match is against only the built files. C<--expect-fail> can
276 be used with C<--match> to search for a commit that adds files that match.
282 Test that the build completes, without running any test case.
284 By default, if the build for the desired I<target> fails to complete,
285 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
286 being that one wants to find a commit which changed state "builds && passes"
287 to "builds && fails". If instead one is interested in which commit broke the
288 build (possibly for particular F<Configure> options), use I<--test-build>
289 to treat a build failure as a failure, not a "skip".
291 Often this option isn't as useful as it first seems, because I<any> build
292 failure will be reported to C<git bisect> as a failure, not just the failure
293 that you're interested in. Generally, to debug a particular problem, it's
294 more useful to use a I<target> that builds properly at the point of interest,
295 and then a test case that runs C<make>. For example:
297 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
298 --expect-fail --force-manifest --target=miniperl make perl
300 will find the first revision capable of building C<DynaLoader> and then
301 C<perl>, without becoming confused by revisions where C<miniperl> won't
308 By default, a build will "skip" if any files listed in F<MANIFEST> are not
309 present. Usually this is useful, as it avoids false-failures. However, there
310 are some long ranges of commits where listed files are missing, which can
311 cause a bisect to abort because all that remain are skipped revisions.
313 In these cases, particularly if the test case uses F<miniperl> and no modules,
314 it may be more useful to force the build to continue, even if files
315 F<MANIFEST> are missing.
321 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
327 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
328 to use F<bisect-runner.pl> to build the current particular perl revision for
329 interactive testing, or for debugging F<bisect-runner.pl>.
331 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
337 Validate the options and arguments, and exit silently if they are valid.
