122 Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use
123 of C<git bisect> as much as possible. With one command (and no other files)
124 it's easy to find out
130 Which commit caused this example code to break?
134 Which commit caused this example code to start working?
138 Which commit added the first to match this regex?
142 Which commit removed the last to match this regex?
146 usually without needing to know which versions of perl to use as start and
149 By default F<bisect.pl> will process all options, then use the rest of the
150 command line as arguments to list C<system> to run a test case. By default,
151 the test case should pass (exit with 0) on earlier perls, and fail (exit
152 non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the
153 earliest stable perl version on which the test case passes, check that it
154 fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to
155 find the commit which caused the failure.
157 Because the test case is the complete argument to C<system>, it is easy to
158 run something other than the F<perl> built, if necessary. If you need to run
159 the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
161 You need a clean checkout to run a bisect, and you can't use the checkout
162 which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
163 a revision before F<Porting/bisect-runner.pl> was added, which
164 C<git bisect run> needs). If your working checkout is called F<perl>, the
165 simplest solution is to make a local clone, and run from that. I<i.e.>:
170 ../perl/Porting/bisect.pl ...
172 By default, F<bisect-runner.pl> will automatically disable the build of
173 L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical
174 to patch DB_File 1.70 and earlier to build with current Berkeley DB headers.
175 (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.)
176 If your F<db.h> is old enough you can override this with C<-Unoextensions>.
184 --start I<commit-ish>
186 Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
187 else C<git> understands as a revision). If not specified, F<bisect.pl> will
188 search stable perl releases until it finds one where the test case passes.
189 The default is to search from 5.002 to 5.14.0. If F<bisect.pl> detects that
190 the checkout is on a case insensitive file system, it will search from
197 Most recent revision to test, as a I<commit-ish>. If not specified, defaults
204 F<Makefile> target (or equivalent) needed, to run the test case. If specified,
205 this should be one of
213 Just run F<./Configure>
219 Run the various F<*.SH> files to generate F<Makefile>, F<config.h>, I<etc>.
231 Use F<miniperl> to build F<lib/Config.pm>
237 Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl>
238 is simple XS module present since 5.000, this provides a fast test of
239 whether XS modules can be built. Note, XS modules are built by F<miniperl>,
240 hence this target will not build F<perl>.
246 Build F<perl>. This also builds pure-Perl modules in F<cpan>, F<dist> and
247 F<ext>. XS modules (such as L<Fcntl>) are not built.
253 Build everything needed to run the tests. This is the default if we're
254 running test code, but is time consuming, as it means building all
255 XS modules. For older F<Makefile>s, the previous name of C<test-prep>
256 is automatically substituted. For very old F<Makefile>s, C<make test> is
257 run, as there is no target provided to just get things ready, and for 5.004
258 and earlier the tests run very quickly.
264 --one-liner 'code to run'
270 Example code to run, just like you'd use with C<perl -e>.
272 This prepends C<./perl -Ilib -e 'code to run'> to the test case given,
273 or F<./miniperl> if I<target> is C<miniperl>.
275 (Usually you'll use C<-e> instead of providing a test case in the
276 non-option arguments to F<bisect.pl>)
278 C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
279 which interferes with detecting errors in the example code itself.
285 Add C<-l> to the command line with C<-e>
287 This will automatically append a newline to every output line of your testcase.
288 Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's
289 not feasible to emulate F<perl>'s somewhat quirky switch parsing with
290 L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write
291 a full test case, instead of using C<bisect.pl>'s C<-e> shortcut.
297 Add C<-w> to the command line with C<-e>
299 It's not valid to pass C<-l> or C<-w> to C<bisect.pl> unless you are also
306 The test case should fail for the I<start> revision, and pass for the I<end>
307 revision. The bisect run will find the first commit where it passes.
311 -Dnoextensions=Encode
319 -Accflags=-DNO_MATHOMS
321 Arguments to pass to F<Configure>. Repeated C<-A> arguments are passed
322 through as is. C<-D> and C<-U> are processed in order, and override
323 previous settings for the same parameter. F<bisect-runner.pl> emulates
324 C<-Dnoextensions> when F<Configure> itself does not provide it, as it's
325 often very useful to be able to disable some XS extensions.
331 The C<make> command to use. If this not set, F<make> is used. If this is
332 set, it also adds a C<-Dmake=...> else some recursive make invocations
333 in extensions may fail. Typically one would use this as C<--make gmake>
334 to use F<gmake> in place of the system F<make>.
344 Number of C<make> jobs to run in parallel. If F</proc/cpuinfo> exists and
345 can be parsed, or F</sbin/sysctl> exists and reports C<hw.ncpu>, or
346 F</usr/bin/getconf> exists and reports C<_NPROCESSORS_ONLN> defaults to 1 +
347 I<number of CPUs>. Otherwise defaults to 2.
353 Instead of running a test program to determine I<pass> or I<fail>, pass
354 if the given regex matches, and hence search for the commit that removes
355 the last matching file. C<--expect-fail> can be used with C<--match> to
356 search for a commit that adds files that match.
358 The remaining command line arguments are treated as glob patterns for files
359 to match against. If none are specified, then they default as follows:
365 If no I<target> is specified, the match is against all files in the
366 repository (which is fast).
370 If a I<target> is specified, that target is built, and the match is against
371 only the built files.
375 Treating the command line arguments as glob patterns should not cause
376 problems, as the perl distribution has never shipped or built files with
377 names that contain characters which are globbing metacharacters.
379 Anything which is not a readable file is ignored, instead of generating an
380 error. (If you want an error, run C<grep> or C<ack> as a test case). This
381 permits one to easily search in a file that changed its name. For example:
383 .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*'
389 Test that the build completes, without running any test case.
391 By default, if the build for the desired I<target> fails to complete,
392 F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption
393 being that one wants to find a commit which changed state "builds && passes"
394 to "builds && fails". If instead one is interested in which commit broke the
395 build (possibly for particular F<Configure> options), use I<--test-build>
396 to treat a build failure as a failure, not a "skip".
398 Often this option isn't as useful as it first seems, because I<any> build
399 failure will be reported to C<git bisect> as a failure, not just the failure
400 that you're interested in. Generally, to debug a particular problem, it's
401 more useful to use a I<target> that builds properly at the point of interest,
402 and then a test case that runs C<make>. For example:
404 .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \
405 --expect-fail --force-manifest --target=miniperl make perl
407 will find the first revision capable of building L<DynaLoader> and then
408 F<perl>, without becoming confused by revisions where F<miniperl> won't
415 By default, a build will "skip" if any files listed in F<MANIFEST> are not
416 present. Usually this is useful, as it avoids false-failures. However, there
417 are some long ranges of commits where listed files are missing, which can
418 cause a bisect to abort because all that remain are skipped revisions.
420 In these cases, particularly if the test case uses F<miniperl> and no modules,
421 it may be more useful to force the build to continue, even if files
422 F<MANIFEST> are missing.
428 Run C<make regen_headers> before building F<miniperl>. This may fix a build
429 that otherwise would skip because the generated headers at that revision
430 are stale. It's not the default because it conceals this error in the true
431 state of such revisions.
437 C<--expect-pass=0> is equivalent to C<--expect-fail>. I<1> is the default.
443 Tell F<bisect-runner.pl> not to clean up after the build. This allows one
444 to use F<bisect-runner.pl> to build the current particular perl revision for
445 interactive testing, or for debugging F<bisect-runner.pl>.
447 Passing this to F<bisect.pl> will likely cause the bisect to fail badly.
453 Test that all stable revisions can be built. By default, attempts to build
454 I<blead>, I<v5.14.0> .. I<perl-5.002> (or I<perl5.005> on a case insensitive
455 file system). Stops at the first failure, without
456 cleaning the checkout. Use I<--start> to specify the earliest revision to
457 test, I<--end> to specify the most recent. Useful for validating a new
458 OS/CPU/compiler combination. For example
460 ../perl/Porting/bisect.pl --validate -le 'print "Hello from $]"'
462 If no testcase is specified, the default is to use F<t/TEST> to run
469 Validate the options and arguments, and exit silently if they are valid.
475 Validate that the test case isn't an executable file with a
476 C<#!/usr/bin/perl> line (or similar). As F<bisect-runner.pl> does B<not>
477 prepend C<./perl> to the test case, a I<#!> line specifying an external
478 F<perl> binary will cause the test case to always run with I<that> F<perl>,
479 not the F<perl> built by the bisect runner. Likely this is not what you
480 wanted. If your test case is actually a wrapper script to run other
481 commands, you should run it with an explicit interpreter, to be clear. For
482 example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
483 run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
