121 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
122 of C<git bisect> as much as possible. With one command (and no other files)
123 it's easy to find out
129 Which commit caused this example code to break?
133 Which commit caused this example code to start working?
137 Which commit added the first to match this regex?
141 Which commit removed the last to match this regex?
145 usually without needing to know which versions of perl to use as start and
148 By default F<bisect.pl> will process all options, then use the rest of the
149 command line as arguments to list C<system> to run a test case. By default,
150 the test case should pass (exit with 0) on earlier perls, and fail (exit
151 non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the
152 earliest stable perl version on which the test case passes, check that it
153 fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to
154 find the commit which caused the failure.
156 Because the test case is the complete argument to C<system>, it is easy to
157 run something other than the F<perl> built, if necessary. If you need to run
158 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
160 You need a clean checkout to run a bisect, and you can't use the checkout
161 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
162 a revision before F<Porting/bisect-runner.pl> was added, which
163 C<git bisect run> needs). If your working checkout is called F<perl>, the
164 simplest solution is to make a local clone, and run from that. I<i.e.>:
169 ../perl/Porting/bisect.pl ...
171 By default, F<bisect-runner.pl> will automatically disable the build of
172 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
173 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
174 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
175 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
183 --start I<commit-ish>
185 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
186 else C<git> understands as a revision). If not specified, F<bisect.pl> will
187 search stable perl releases from 5.002 to 5.14.0 until it finds one where
188 the test case passes.
194 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
201 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
202 this should be one of
210 Just run F<./Configure>
216 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
228 Use F<miniperl> to build F<lib/Config.pm>
234 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
235 is simple XS module present since 5.000, this provides a fast test of
236 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
237 hence this target will not build F<perl>.
243 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
244 F<ext>. XS modules (such as L<Fcntl>) are not built.
250 Build everything needed to run the tests. This is the default if we're
251 running test code, but is time consuming, as it means building all
252 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
253 is automatically substituted. For very old F<Makefile>s, C<make test> is
254 run, as there is no target provided to just get things ready, and for 5.004
255 and earlier the tests run very quickly.
261 --one-liner 'code to run'
267 Example code to run, just like you'd use with C<perl -e>.
269 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
270 or F<./miniperl> if I<target> is C<miniperl>.
272 (Usually you'll use C<-e> instead of providing a test case in the
273 non-option arguments to F<bisect.pl>)
275 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
276 which interferes with detecting errors in the example code itself.
282 Add C<-l> to the command line with C<-e>
284 This will automatically append a newline to every output line of your testcase.
285 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
286 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
287 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
288 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
294 Add C<-w> to the command line with C<-e>
296 It's not valid to pass C<-l> or C<-w> to C<bisect.pl> unless you are also
303 The test case should fail for the I<start> revision, and pass for the I<end>
304 revision. The bisect run will find the first commit where it passes.
308 -Dnoextensions=Encode
316 -Accflags=-DNO_MATHOMS
318 Arguments to pass to F<Configure>. Repeated C<-A> arguments are passed
319 through as is. C<-D> and C<-U> are processed in order, and override
320 previous settings for the same parameter. F<bisect-runner.pl> emulates
321 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
322 often very useful to be able to disable some XS extensions.
328 The C<make> command to use. If this not set, F<make> is used. If this is
329 set, it also adds a C<-Dmake=...> else some recursive make invocations
330 in extensions may fail. Typically one would use this as C<--make gmake>
331 to use F<gmake> in place of the system F<make>.
341 Number of C<make> jobs to run in parallel. If F</proc/cpuinfo> exists and
342 can be parsed, or F</sbin/sysctl> exists and reports C<hw.ncpu>, or
343 F</usr/bin/getconf> exists and reports C<_NPROCESSORS_ONLN> defaults to 1 +
344 I<number of CPUs>. Otherwise defaults to 2.
350 Instead of running a test program to determine I<pass> or I<fail>, pass
351 if the given regex matches, and hence search for the commit that removes
352 the last matching file.
354 If no I<target> is specified, the match is against all files in the
355 repository (which is fast). If a I<target> is specified, that target is
356 built, and the match is against only the built files. C<--expect-fail> can
357 be used with C<--match> to search for a commit that adds files that match.
363 Test that the build completes, without running any test case.
365 By default, if the build for the desired I<target> fails to complete,
366 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
367 being that one wants to find a commit which changed state "builds && passes"
368 to "builds && fails". If instead one is interested in which commit broke the
369 build (possibly for particular F<Configure> options), use I<--test-build>
370 to treat a build failure as a failure, not a "skip".
372 Often this option isn't as useful as it first seems, because I<any> build
373 failure will be reported to C<git bisect> as a failure, not just the failure
374 that you're interested in. Generally, to debug a particular problem, it's
375 more useful to use a I<target> that builds properly at the point of interest,
376 and then a test case that runs C<make>. For example:
378 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
379 --expect-fail --force-manifest --target=miniperl make perl
381 will find the first revision capable of building L<DynaLoader> and then
382 F<perl>, without becoming confused by revisions where F<miniperl> won't
389 By default, a build will "skip" if any files listed in F<MANIFEST> are not
390 present. Usually this is useful, as it avoids false-failures. However, there
391 are some long ranges of commits where listed files are missing, which can
392 cause a bisect to abort because all that remain are skipped revisions.
394 In these cases, particularly if the test case uses F<miniperl> and no modules,
395 it may be more useful to force the build to continue, even if files
396 F<MANIFEST> are missing.
402 Run C<make regen_headers> before building F<miniperl>. This may fix a build
403 that otherwise would skip because the generated headers at that revision
404 are stale. It's not the default because it conceals this error in the true
405 state of such revisions.
411 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
417 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
418 to use F<bisect-runner.pl> to build the current particular perl revision for
419 interactive testing, or for debugging F<bisect-runner.pl>.
421 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
427 Test that all stable revisions can be built. By default, attempts to build
428 I<blead>, I<v5.14.0> .. I<perl-5.002>. Stops at the first failure, without
429 cleaning the checkout. Use I<--start> to specify the earliest revision to
430 test, I<--end> to specify the most recent. Useful for validating a new
431 OS/CPU/compiler combination. For example
433 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
435 If no testcase is specified, the default is to use F<t/TEST> to run
442 Validate the options and arguments, and exit silently if they are valid.
448 Validate that the test case isn't an executable file with a
449 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
450 prepend C<./perl> to the test case, a I<#!> line specifying an external
451 F<perl> binary will cause the test case to always run with I<that> F<perl>,
452 not the F<perl> built by the bisect runner. Likely this is not what you
453 wanted. If your test case is actually a wrapper script to run other
454 commands, you should run it with an explicit interpreter, to be clear. For
455 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
456 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
