162 | =head1 DESCRIPTION | |
163 | ||
facd1b88 | 164 | Together F<bisect.pl> and F<bisect-runner.pl> attempt to automate the use |
77ae6092 NC |
165 | of C<git bisect> as much as possible. With one command (and no other files) |
166 | it's easy to find out | |

187 | ||
188 | usually without needing to know which versions of perl to use as start and | |
189 | end revisions. | |
190 | ||
facd1b88 | 191 | By default F<bisect.pl> will process all options, then use the rest of the |
77ae6092 NC |
192 | command line as arguments to list C<system> to run a test case. By default, |
193 | the test case should pass (exit with 0) on earlier perls, and fail (exit | |
06a5399c NC |
194 | non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the |
195 | earliest stable perl version on which the test case passes, check that it | |
196 | fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to | |
197 | find the commit which caused the failure. | |
198 | ||
199 | Many of perl's own test scripts exit 0 even if their TAP reports test | |
200 | failures, and some need particular setup (such as running from the right | |
201 | directory, or adding C<-T> to the command line). Hence if you want to bisect | |
202 | a test script, you can specify it with the I<--target> option, and it will | |
203 | be invoked using F<t/TEST> which performs all the setup, and exits non-zero | |
204 | if the TAP reports failures. This works for any file ending C<.t>, so you can | |
205 | use it with a file outside of the working checkout, for example to test a | |
206 | particular version of a test script, as a path inside the repository will | |
207 | (of course) be testing the version of the script checked out for the current | |
208 | revision, which may be too early to have the test you are interested in. | |
77ae6092 NC |
209 | |
210 | Because the test case is the complete argument to C<system>, it is easy to | |
211 | run something other than the F<perl> built, if necessary. If you need to run | |
e3caab27 NC |
212 | the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>. |
213 | As a special case, if the first argument of the test case is a readable file | |
214 | (whether executable or not), matching C<qr{\A#!./(?:mini)?perl\b}> then it | |
215 | will have C<./perl> <-Ilib> (or C<./miniperl>) prepended to it. | |
77ae6092 | 216 | |
91bcfbd8 NC |
217 | You need a clean checkout to run a bisect. You can use the checkout |
218 | containing F<Porting/bisect.pl> if you wish - in this case | |
219 | F<Porting/bisect.pl> will copy F<Porting/bisect-runner.pl> to a temporary | |
220 | file generated by C<File::Temp::tempfile()>. If doing this, beware that when | |
221 | the bisect ends (or you abort it) then your checkout is no longer at | |
222 | C<blead>, so you will need to C<git checkout blead> before restarting, to | |
223 | get the current version of F<Porting/bisect.pl> again. It's often easier | |
224 | either to copy F<Porting/bisect.pl> and F<Porting/bisect-runner.pl> to | |
225 | another directory (I<e.g.> F<~/bin>, if you have one), or to create a second | |
226 | git repository for running bisect. To create a second local repository, if | |
227 | your working checkout is called F<perl>, a simple solution is to make a | |
228 | local clone, and run from that. I<i.e.>: | |
5842706e NC |
229 | |
230 | cd .. | |
231 | git clone perl perl2 | |
232 | cd perl2 | |
233 | ../perl/Porting/bisect.pl ... | |
234 | ||
facd1b88 | 235 | By default, F<bisect-runner.pl> will automatically disable the build of |
cfadff5f NC |
236 | L<DB_File> for commits earlier than ccb44e3bf3be2c30, as it's not practical |
237 | to patch DB_File 1.70 and earlier to build with current Berkeley DB headers. | |
238 | (ccb44e3bf3be2c30 was in September 1999, between 5.005_62 and 5.005_63.) | |
239 | If your F<db.h> is old enough you can override this with C<-Unoextensions>. | |

248 | ||
249 | Earliest revision to test, as a I<commit-ish> (a tag, commit or anything | |
facd1b88 | 250 | else C<git> understands as a revision). If not specified, F<bisect.pl> will |
91bcfbd8 NC |
251 | search stable .0 perl releases until it finds one where the test case |
252 | passes. The default is to search from 5.002 to the most recent tagged stable | |
253 | release (v5.18.0 at the time of writing). If F<bisect.pl> detects that the | |
f66c64b1 NC |
254 | checkout is on a case insensitive file system, it will search from 5.005 to |
255 | the most recent tagged stable release. Only .0 stable releases are used | |
256 | because these are the only stable releases that are parents of blead, and | |
257 | hence suitable for a bisect run. | |

309 | I<Fcntl> |
310 | ||
311 | Build F<lib/auto/Fcntl/Fnctl.so> (strictly, C<.$Config{so}>). As L<Fcntl> | |
312 | is simple XS module present since 5.000, this provides a fast test of | |
b4f0ec5f | 313 | whether XS modules can be built. Note, XS modules are built by F<miniperl>, |
2526f4b8 NC |
314 | hence this target will not build F<perl>. |

325 | I<test_prep> |
326 | ||
327 | Build everything needed to run the tests. This is the default if we're | |
328 | running test code, but is time consuming, as it means building all | |
b4f0ec5f | 329 | XS modules. For older F<Makefile>s, the previous name of C<test-prep> |
77ae6092 NC |
330 | is automatically substituted. For very old F<Makefile>s, C<make test> is |
331 | run, as there is no target provided to just get things ready, and for 5.004 | |
332 | and earlier the tests run very quickly. | |

377 | Note that you can't specify an argument to F<perl>'s C<-l> with this, as it's | |
378 | not feasible to emulate F<perl>'s somewhat quirky switch parsing with | |
379 | L<Getopt::Long>. If you need the full flexibility of C<-l>, you need to write | |

451 | --no-match pattern | |
452 | ||
453 | Instead of running a test program to determine I<pass> or I<fail>, | |
454 | C<--match> will pass if the given regex matches, and hence search for the | |
455 | commit that removes the last matching file. C<--no-match> inverts the test, | |
456 | to search for the first commit that adds files that match. | |
bf8fb529 NC |
457 | |
458 | The remaining command line arguments are treated as glob patterns for files | |
459 | to match against. If none are specified, then they default as follows: | |
460 | ||
461 | =over 4 | |
462 | ||
463 | =item * | |
77ae6092 NC |
464 | |
465 | If no I<target> is specified, the match is against all files in the | |
bf8fb529 NC |
466 | repository (which is fast). |
467 | ||
468 | =item * | |
469 | ||
470 | If a I<target> is specified, that target is built, and the match is against | |
471 | only the built files. | |
472 | ||
473 | =back | |
474 | ||
475 | Treating the command line arguments as glob patterns should not cause | |
476 | problems, as the perl distribution has never shipped or built files with | |
477 | names that contain characters which are globbing metacharacters. | |
478 | ||
479 | Anything which is not a readable file is ignored, instead of generating an | |
480 | error. (If you want an error, run C<grep> or C<ack> as a test case). This | |
481 | permits one to easily search in a file that changed its name. For example: | |
482 | ||
483 | .../Porting/bisect.pl --match 'Pod.*Functions' 'pod/buildtoc*' | |
77ae6092 | 484 | |
66b521dd NC |

54c7e1f0 NC |
489 | --valgrind |
490 | ||
491 | Run the test program under C<valgrind>. If you need to test for memory | |
492 | errors when parsing invalid programs, the default parser fail exit code of | |
493 | 255 will always override C<valgrind>, so try putting the test case invalid | |
494 | code inside a I<string> C<eval>, so that the perl interpreter will exit with 0. | |
495 | (Be sure to check the output of $@, to avoid missing mistakes such as | |
496 | unintended C<eval> failures due to incorrect C<@INC>) | |
497 | ||
498 | Specifically, this option prepends C<valgrind> C<--error-exitcode=124> to | |
499 | the command line that runs the testcase, to cause valgrind to exit non-zero | |
500 | if it detects errors, with the assumption that the test program itself | |
501 | always exits with zero. If you require more flexibility than this, either | |
502 | specify your C<valgrind> invocation explicitly as part of the test case, or | |
503 | use a wrapper script to control the command line or massage the exit codes. | |

507 | --test-build |
508 | ||
509 | Test that the build completes, without running any test case. | |
510 | ||
511 | By default, if the build for the desired I<target> fails to complete, | |
512 | F<bisect-runner.pl> reports a I<skip> back to C<git bisect>, the assumption | |
513 | being that one wants to find a commit which changed state "builds && passes" | |
514 | to "builds && fails". If instead one is interested in which commit broke the | |
515 | build (possibly for particular F<Configure> options), use I<--test-build> | |
516 | to treat a build failure as a failure, not a "skip". | |
517 | ||
b4f0ec5f NC |
518 | Often this option isn't as useful as it first seems, because I<any> build |
519 | failure will be reported to C<git bisect> as a failure, not just the failure | |
520 | that you're interested in. Generally, to debug a particular problem, it's | |
521 | more useful to use a I<target> that builds properly at the point of interest, | |
522 | and then a test case that runs C<make>. For example: | |
523 | ||
524 | .../Porting/bisect.pl --start=perl-5.000 --end=perl-5.002 \ | |
525 | --expect-fail --force-manifest --target=miniperl make perl | |
526 | ||
facd1b88 NC |
527 | will find the first revision capable of building L<DynaLoader> and then |
528 | F<perl>, without becoming confused by revisions where F<miniperl> won't | |
b4f0ec5f NC |
529 | even link. |

532 | ||
b4f0ec5f NC |
533 | --force-manifest |
534 | ||
77ae6092 NC |
535 | By default, a build will "skip" if any files listed in F<MANIFEST> are not |
536 | present. Usually this is useful, as it avoids false-failures. However, there | |
537 | are some long ranges of commits where listed files are missing, which can | |
538 | cause a bisect to abort because all that remain are skipped revisions. | |
539 | ||
540 | In these cases, particularly if the test case uses F<miniperl> and no modules, | |
541 | it may be more useful to force the build to continue, even if files | |
542 | F<MANIFEST> are missing. | |

544 | =item * | |
545 | ||
bfa52998 NC |
546 | --force-regen |

548 | Run C<make regen_headers> before building F<miniperl>. This may fix a build | |
549 | that otherwise would skip because the generated headers at that revision | |
550 | are stale. It's not the default because it conceals this error in the true | |
551 | state of such revisions. | |

576 | --all-fixups |
577 | ||
578 | F<bisect-runner.pl> will minimally patch various files on a platform and | |
579 | version dependent basis to get the build to complete. Normally it defers | |
580 | doing this as long as possible - C<.SH> files aren't patched until after | |
581 | F<Configure> is run, and C<C> and C<XS> code isn't patched until after | |
582 | F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are | |
583 | done before running C<Configure>. In rare cases adding this may cause a | |
584 | bisect to abort, because an inapplicable patch or other fixup is attempted | |
6c728274 | 585 | for a revision which would usually have already I<skip>ped. If this happens, |

622 | Otherwise, for C<=~>, if it contains a line matching I<pattern>, then the | |
623 | file is fed to C<patch -p1> on standard input. For C<=~>, the patch is | |
624 | applied if no lines match the pattern. | |
625 | ||
626 | As the empty pattern in Perl is a special case (it matches the most recent | |
627 | sucessful match) which is not useful here, an the treatment of empty pattern | |
628 | is special-cased. C<I<filename> =~ //> applies the patch if filename is | |
629 | present. C<I<filename> !~ //> applies the patch if filename missing. This | |
630 | makes it easy to unconditionally apply patches to files, and to use a patch | |
631 | as a way of creating a new file. | |
632 | ||

1240 | # Commit 1cfa4ec74d4933da adds ignore_versioned_solibs to Configure, and sets it |
1241 | # to true in hints/linux.sh | |
1242 | # On dromedary, from that point on, Configure (by default) fails to find any | |
1243 | # libraries, because it scans /usr/local/lib /lib /usr/lib, which only contain | |
1244 | # versioned libraries. Without -lm, the build fails. | |
1245 | # Telling /usr/local/lib64 /lib64 /usr/lib64 works from that commit onwards, | |
1246 | # until commit faae14e6e968e1c0 adds it to the hints. | |
1247 | # However, prior to 1cfa4ec74d4933da telling Configure the truth doesn't work, | |
1248 | # because it will spot versioned libraries, pass them to the compiler, and then | |
1249 | # bail out pretty early on. Configure won't let us override libswanted, but it | |
1250 | # will let us override the entire libs list. | |
