113 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
114 of C<git bisect> as much as possible. With one command (and no other files)
115 it's easy to find out
121 Which commit caused this example code to break?
125 Which commit caused this example code to start working?
129 Which commit added the first to match this regex?
133 Which commit removed the last to match this regex?
137 usually without needing to know which versions of perl to use as start and
140 By default F<bisect.pl> will process all options, then use the rest of the
141 command line as arguments to list C<system> to run a test case. By default,
142 the test case should pass (exit with 0) on earlier perls, and fail (exit
143 non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the
144 earliest stable perl version on which the test case passes, check that it
145 fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to
146 find the commit which caused the failure.
148 Because the test case is the complete argument to C<system>, it is easy to
149 run something other than the F<perl> built, if necessary. If you need to run
150 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
152 You need a clean checkout to run a bisect, and you can't use the checkout
153 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
154 a revision before F<Porting/bisect-runner.pl> was added, which
155 C<git bisect run> needs). If your working checkout is called F<perl>, the
156 simplest solution is to make a local clone, and run from that. I<i.e.>:
161 ../perl/Porting/bisect.pl ...
163 By default, F<bisect-runner.pl> will automatically disable the build of
164 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
165 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
166 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
167 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
175 --start I<commit-ish>
177 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
178 else C<git> understands as a revision). If not specified, F<bisect.pl> will
179 search stable perl releases from 5.002 to 5.14.0 until it finds one where
180 the test case passes.
186 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
193 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
194 this should be one of
202 Just run F<./Configure>
208 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
220 Use F<miniperl> to build F<lib/Config.pm>
226 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
227 is simple XS module present since 5.000, this provides a fast test of
228 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
229 hence this target will not build F<perl>.
235 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
236 F<ext>. XS modules (such as L<Fcntl>) are not built.
242 Build everything needed to run the tests. This is the default if we're
243 running test code, but is time consuming, as it means building all
244 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
245 is automatically substituted. For very old F<Makefile>s, C<make test> is
246 run, as there is no target provided to just get things ready, and for 5.004
247 and earlier the tests run very quickly.
253 --one-liner 'code to run'
259 Example code to run, just like you'd use with C<perl -e>.
261 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
262 or F<./miniperl> if I<target> is C<miniperl>.
264 (Usually you'll use C<-e> instead of providing a test case in the
265 non-option arguments to F<bisect.pl>)
267 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
268 which interferes with detecting errors in the example code itself.
274 The test case should fail for the I<start> revision, and pass for the I<end>
275 revision. The bisect run will find the first commit where it passes.
279 -Dnoextensions=Encode
287 -Accflags=-DNO_MATHOMS
289 Arguments to pass to F<Configure>. Repeated C<-A> arguments are passed
290 through as is. C<-D> and C<-U> are processed in order, and override
291 previous settings for the same parameter. F<bisect-runner.pl> emulates
292 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
293 often very useful to be able to disable some XS extensions.
303 Number of C<make> jobs to run in parallel. If F</proc/cpuinfo> exists and
304 can be parsed, or F</sbin/sysctl> exists and reports C<hw.ncpu>, or
305 F</usr/bin/getconf> exists and reports C<_NPROCESSORS_ONLN> defaults to 1 +
306 I<number of CPUs>. Otherwise defaults to 2.
312 Instead of running a test program to determine I<pass> or I<fail>, pass
313 if the given regex matches, and hence search for the commit that removes
314 the last matching file.
316 If no I<target> is specified, the match is against all files in the
317 repository (which is fast). If a I<target> is specified, that target is
318 built, and the match is against only the built files. C<--expect-fail> can
319 be used with C<--match> to search for a commit that adds files that match.
325 Test that the build completes, without running any test case.
327 By default, if the build for the desired I<target> fails to complete,
328 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
329 being that one wants to find a commit which changed state "builds && passes"
330 to "builds && fails". If instead one is interested in which commit broke the
331 build (possibly for particular F<Configure> options), use I<--test-build>
332 to treat a build failure as a failure, not a "skip".
334 Often this option isn't as useful as it first seems, because I<any> build
335 failure will be reported to C<git bisect> as a failure, not just the failure
336 that you're interested in. Generally, to debug a particular problem, it's
337 more useful to use a I<target> that builds properly at the point of interest,
338 and then a test case that runs C<make>. For example:
340 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
341 --expect-fail --force-manifest --target=miniperl make perl
343 will find the first revision capable of building L<DynaLoader> and then
344 F<perl>, without becoming confused by revisions where F<miniperl> won't
351 By default, a build will "skip" if any files listed in F<MANIFEST> are not
352 present. Usually this is useful, as it avoids false-failures. However, there
353 are some long ranges of commits where listed files are missing, which can
354 cause a bisect to abort because all that remain are skipped revisions.
356 In these cases, particularly if the test case uses F<miniperl> and no modules,
357 it may be more useful to force the build to continue, even if files
358 F<MANIFEST> are missing.
364 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
370 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
371 to use F<bisect-runner.pl> to build the current particular perl revision for
372 interactive testing, or for debugging F<bisect-runner.pl>.
374 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
380 Validate the options and arguments, and exit silently if they are valid.
394 Display the usage information and exit.

1550 # On dromedary, from that point on, Configure (by default) fails to find any

1552 # versioned libraries. Without -lm, the build fails.
