c67d51c3 |
5 | As of August 2009, this file is mostly complete, although it is missing |
6 | some detail on doing a major release (e.g. 5.10.0 -> 5.12.0). Note that |
d60a1044 |
7 | things change at each release, so there may be new things not covered |
8 | here, or tools may need updating. |

10 | =head1 SYNOPSIS |
11 | |
f6af4394 |
12 | This document describes the series of tasks required - some automatic, some |
13 | manual - to produce a perl release of some description, be that a snaphot, |
8c35d285 |
14 | release candidate, or final, numbered release of maint or blead. |
f6af4394 |
15 | |
8c35d285 |
16 | The release process has traditionally been executed by the current |
17 | pumpking. |
7277a900 |
18 | |
8c35d285 |
19 | This document both helps as a check-list for the release engineer |
20 | and is a base for ideas on how the various tasks could be automated |
21 | or distributed. |

23 | The outline of a typical release cycle is as follows: |
f6af4394 |
24 | |
636a1918 |
25 | (5.10.1 is released, and post-release actions have been done) |
f6af4394 |
26 | |
27 | ...time passes... |
28 | |
29 | an occasional snapshot is released, that still identifies itself as |
30 | 5.10.1 |
31 | |
32 | ...time passes... |
33 | |
34 | a few weeks before the release, a number of steps are performed, |
35 | including bumping the version to 5.10.2 |
636a1918 |
36 | |
37 | ...a few weeks passes... |
46743ef7 |
38 | |
f6af4394 |
39 | perl-5.10.2-RC1 is released |
40 | |
41 | perl-5.10.2 is released |
42 | |
43 | post-release actions are performed, including creating new |
44 | perl5103delta.pod |
45 | |
46 | ... the cycle continues ... |

48 | =head1 DETAILS |
49 | |
8c35d285 |
50 | Some of the tasks described below apply to all four types of |
51 | release of Perl. (snapshot, RC, final release of maint, final |
52 | release of blead). Some of these tasks apply only to a subset |
53 | of these release types. If a step does not apply to a given |
54 | type of release, you will see a notation to that effect at |
55 | the beginning of the step. |
56 | |
57 | =head2 Release types |
58 | |
59 | =over 4 |
60 | |
61 | =item Snapshot |
62 | |
63 | A snapshot is intended to encourage in-depth testing from time-to-time, |
64 | for example after a key point in the stabilisation of a branch. It |
65 | requires fewer steps than a full release, and the version number of perl in |
66 | the tarball will usually be the same as that of the previous release. |
67 | |
68 | =item Release Candidate (RC) |
69 | |
d60a1044 |
70 | A release candidate is an attempt to produce a tarball that is a close as |
71 | possible to the final release. Indeed, unless critical faults are found |
72 | during the RC testing, the final release will be identical to the RC |
73 | barring a few minor fixups (updating the release date in F<perlhist.pod>, |
74 | removing the RC status from F<patchlevel.h>, etc). If faults are found, |
75 | then the fixes should be put into a new release candidate, never directly |
76 | into a final release. |
8c35d285 |
77 | |
78 | =item Stable/Maint release |
79 | |
80 | At this point you should have a working release candidate with few or no |
81 | changes since. |
82 | |
83 | It's essentially the same procedure as for making a release candidate, but |
84 | with a whole bunch of extra post-release steps. |
85 | |
86 | =item Blead release |
87 | |
88 | It's essentially the same procedure as for making a release candidate, but |
89 | with a whole bunch of extra post-release steps. |

93 | =head2 Prerequisites |
94 | |
95 | Before you can make an official release of perl, there are a few |
96 | hoops you need to jump through: |
97 | |
98 | =over 4 |
99 | |
8c35d285 |
100 | =item PAUSE account |
101 | |
102 | I<SKIP this step for SNAPSHOT> |
fd838dcf |
103 | |
104 | Make sure you have a PAUSE account suitable for uploading a perl release. |
105 | If you don't have a PAUSE account, then request one: |
106 | |
107 | https://pause.perl.org/pause/query?ACTION=request_id |
108 | |
109 | Check that your account is allowed to upload perl distros: goto |
110 | https://pause.perl.org/, login, then select 'upload file to CPAN'; there |
111 | should be a "For pumpkings only: Send a CC" tickbox. If not, ask Andreas |
112 | König to add your ID to the list of people allowed to upload something |
113 | called perl. You can find Andreas' email address at: |
4d2c8158 |
114 | |

115 | https://pause.perl.org/pause/query?ACTION=pause_04imprint |
116 | |
8c35d285 |
117 | =item CPAN mirror |
118 | |
119 | Some release engineering steps require a full mirror of the CPAN. |
120 | Work to fall back to using a remote mirror via HTTP is incomplete |
121 | but ongoing. (No, a minicpan mirror is not sufficient) |
122 | |
123 | =item git checkout and commit bit |
fd838dcf |
124 | |
125 | You will need a working C<git> installation, checkout of the perl |
126 | git repository and perl commit bit. For information about working |
127 | with perl and git, see F<pod/perlrepository.pod>. |
128 | |
129 | If you are not yet a perl committer, you won't be able to make a |
130 | release. Have a chat with whichever evil perl porter tried to talk |
131 | you into the idea in the first place to figure out the best way to |
132 | resolve the issue. |

8c35d285 |
139 | For a numbered blead or maint release of perl, you will need a quotation |
140 | to use as an epigraph to your release announcement. (There's no harm |
141 | in having one for a snapshot, but it's not required). |

147 | =head2 Building a release - advance actions |
8c35d285 |
148 | |
149 | The work of building a release candidate for a numbered release of |
150 | perl generally starts several weeks before the first release candidate. |
52a66c2c |
151 | Some of the following steps should be done regularly, but all I<must> be |
152 | done in the run up to a release. |

159 | |
f6af4394 |
160 | Ensure that dual-life CPAN modules are synchronised with CPAN. Basically, |
161 | run the following: |
162 | |
db3f805e |
163 | $ ./perl -Ilib Porting/core-cpan-diff -a -o /tmp/corediffs |
7277a900 |
164 | |
f6af4394 |
165 | to see any inconsistencies between the core and CPAN versions of distros, |
166 | then fix the core, or cajole CPAN authors as appropriate. See also the |
167 | C<-d> and C<-v> options for more detail. You'll probably want to use the |
168 | C<-c cachedir> option to avoid repeated CPAN downloads. |
7277a900 |
169 | |
f6af4394 |
170 | To see which core distro versions differ from the current CPAN versions: |
7277a900 |
171 | |
db3f805e |
172 | $ ./perl -Ilib Porting/core-cpan-diff -x -a |
7277a900 |
173 | |
52a66c2c |
174 | If you are making a maint release, run C<core-cpan-diff> on both blead and |
636a1918 |
175 | maint, then diff the two outputs. Compare this with what you expect, and if |
176 | necessary, fix things up. For example, you might think that both blead |
177 | and maint are synchronised with a particular CPAN module, but one might |
178 | have some extra changes. |

184 | Ensure dual-life CPAN modules are stable, which comes down to: |
7277a900 |
185 | |
186 | for each module that fails its regression tests on $current |
f6af4394 |
187 | did it fail identically on $previous? |
188 | if yes, "SEP" (Somebody Else's Problem) |
189 | else work out why it failed (a bisect is useful for this) |
7277a900 |
190 | |
191 | attempt to group failure causes |
192 | |
193 | for each failure cause |
f6af4394 |
194 | is that a regression? |
195 | if yes, figure out how to fix it |
196 | (more code? revert the code that broke it) |
197 | else |
198 | (presumably) it's relying on something un-or-under-documented |
199 | should the existing behaviour stay? |
200 | yes - goto "regression" |
201 | no - note it in perldelta as a significant bugfix |
202 | (also, try to inform the module's author) |

221 | Run F<Porting/cmpVERSION.pl> to compare the current source tree with the |
222 | previous version to check for for modules that have identical version |
223 | numbers but different contents, e.g.: |
7277a900 |
224 | |
f6af4394 |
225 | $ cd ~/some-perl-root |
226 | $ ./perl -Ilib Porting/cmpVERSION.pl -xd ~/my_perl-tarballs/perl-5.10.0 . |
227 | |
228 | then bump the version numbers of any non-dual-life modules that have |
229 | changed since the previous release, but which still have the old version |
230 | number. If there is more than one maintenance branch (e.g. 5.8.x, 5.10.x), |
231 | then compare against both. |
232 | |
233 | Note that some of the files listed may be generated (e.g. copied from ext/ |
234 | to lib/, or a script like lib/lib_pm.PL is run to produce lib/lib.pm); |
235 | make sure you edit the correct file! |
236 | |
237 | Once all version numbers have been bumped, re-run the checks. |
238 | |
239 | Then run again without the -x option, to check that dual-life modules are |
240 | also sensible. |

db3f805e |
247 | |
636a1918 |
248 | Peruse F<Porting/how_to_write_a_perldelta.pod>, and try to make sure that |
249 | every section it lists is, if necessary, populated and complete. Copy |

256 | A week or two before the first release candidate, bump the perl version |
257 | number (e.g. from 5.10.0 to 5.10.1), to allow sufficient time for testing |
258 | and smoking with the target version built into the perl executable. For |
259 | subsequent release candidates and the final release, it it not necessary |
260 | to bump the version further. |
f6af4394 |
261 | |
262 | There is a tool to semi-automate this process. It works in two stages. |
263 | First, it generates a list of suggested changes, which you review and |
264 | edit; then you feed this list back and it applies the edits. So, first |
52a66c2c |
265 | scan the source directory looking for likely candidates. The command line |
266 | arguments are the old and new version numbers, and -s means scan: |
f6af4394 |
267 | |
268 | $ Porting/bump-perl-version -s 5.10.0 5.10.1 > /tmp/scan |
269 | |
52a66c2c |
270 | This produces a file containing a list of suggested edits, e.g.: |
f6af4394 |
271 | |
272 | NetWare/Makefile |
273 | |
274 | 89: -MODULE_DESC = "Perl 5.10.0 for NetWare" |
275 | +MODULE_DESC = "Perl 5.10.1 for NetWare" |
276 | |
277 | i.e. in the file F<NetWare/Makefile>, line 89 would be changed as shown. |
278 | Review the file carefully, and delete any -/+ line pairs that you don't |
52a66c2c |
279 | want changing. You can also edit just the C<+> line to change the |
280 | suggested replacement text. Remember that this tool is largely just |
281 | grepping for '5.10.0' or whatever, so it will generate false positives. Be |
282 | careful not change text like "this was fixed in 5.10.0"! Then run: |
f6af4394 |
283 | |
284 | $ Porting/bump-perl-version -u < /tmp/scan |
285 | |
286 | which will update all the files shown; then commit the changes. |
287 | |
288 | Be particularly careful with F<INSTALL>, which contains a mixture of |
289 | C<5.10.0>-type strings, some of which need bumping on every release, and |
52a66c2c |
290 | some of which need to be left unchanged. Also note that this tool |
291 | currently only detects a single substitution per line: so in particular, |
292 | this line in README.vms needs special handling: |
f6af4394 |
293 | |
294 | rename perl-5^.10^.1.dir perl-5_10_1.dir |

308 | Update the F<Changes> file to contain the git log command which would show |
309 | all the changes in this release. You will need assume the existence of a |
310 | not-yet created tag for the forthcoming release; e.g. |
7277a900 |
311 | |

312 | git log ... perl-5.10.0..perl-5.12.0 |
7277a900 |
313 | |
f6af4394 |
314 | Due to warts in the perforce-to-git migration, some branches require extra |
315 | exclusions to avoid other branches being pulled in. Make sure you have the |
316 | correct incantation: replace the not-yet-created tag with C<HEAD> and see |
52a66c2c |
317 | if C<git log> produces roughly the right number of commits across roughly the |
318 | right time period (you may find C<git log --pretty=oneline | wc> useful). |

430 | Update C<Module::Corelist> with module version data for the new release. |
bfadf2ba |
431 | |
432 | Note that if this is a maint release, you should run the following actions |
dd0e54ba |
433 | from the maint directory, but commit the C<Corelist.pm> changes in |
434 | I<blead> and subsequently cherry-pick it. |
bfadf2ba |
435 | |
a0db33fe |
436 | F<corelist.pl> uses ftp.funet.fi to verify information about dual-lived |
bfadf2ba |
437 | modules on CPAN. It can use a full, local CPAN mirror or fall back |
438 | to C<wget> or C<curl> to fetch only package metadata remotely. |
439 | |
440 | (If you'd prefer to have a full CPAN mirror, see |
441 | http://www.cpan.org/misc/cpan-faq.html#How_mirror_CPAN) |
442 | |
a0db33fe |
443 | Then change to your perl checkout, and if necessary, |

444 | |
a0db33fe |
445 | $ make perl |

446 | |
52a66c2c |
447 | If this not the first update for this version, first edit |
2ce7d676 |
448 | F<ext/Module-CoreList/lib/Module/CoreList.pm> to delete the existing |
449 | entries for this version from the C<%released> and C<%version> hashes: |
450 | they will have a key like C<5.010001> for 5.10.1. |
52a66c2c |
451 | |
452 | XXX the edit-in-place functionality of Porting/corelist.pl should |
453 | be fixed to handle this automatically. |
454 | |
bf8ea215 |
455 | Then, If you have a local CPAN mirror, run: |
bfadf2ba |
456 | |
bfadf2ba |
457 | $ ./perl -Ilib Porting/corelist.pl ~/my-cpan-mirror |
458 | |
459 | Otherwise, run: |
460 | |
bfadf2ba |
461 | $ ./perl -Ilib Porting/corelist.pl cpan |
462 | |
52a66c2c |
463 | This will chug for a while, possibly reporting various warnings about |
464 | badly-indexed CPABN modules unreltaed to the modules actually in core. |
2ce7d676 |
465 | Assuming all goes well, it will update |
466 | F<ext/Module-CoreList/lib/Module/CoreList.pm>. |
bfadf2ba |
467 | |
468 | Check that file over carefully: |
469 | |
2ce7d676 |
470 | $ git diff ext/Module-CoreList/lib/Module/CoreList.pm |
bfadf2ba |
471 | |
bfadf2ba |
472 | If necessary, bump C<$VERSION> (there's no need to do this for |
473 | every RC; in RC1, bump the version to a new clean number that will |
474 | appear in the final release, and leave as-is for the later RCs and final). |
475 | |
476 | Edit the version number in the new C<< 'Module::CoreList' => 'X.YZ' >> |
477 | entry, as that is likely to reflect the previous version number. |
478 | |
a0db33fe |
479 | In addition, if this is a final release (rather than a release candidate): |
bfadf2ba |

591 | $ perl Porting/makerel -b # for a final release |
592 | |
593 | This creates the directory F<../perl-x.y.z-RC1> or similar, copies all |
594 | the MANIFEST files into it, sets the correct permissions on them, |
595 | adds DOS line endings to some, then tars it up as |
596 | F<../perl-x.y.z-RC1.tar.gz>. With C<-b>, it also creates a C<tar.bz2> file. |

847 | Then manually edit (F<vms/descrip_mms.template> to bump the version |
848 | in the following entry: |
57433fbf |
849 | |
75a012fe |
850 | [.pod]perldelta.pod : [.pod]perl5101delta.pod |
851 | |
852 | XXX this previous step needs to fixed to automate it in pod/buildtoc. |
853 | |
854 | Manually update references to the perlNNNdelta version in these files: |
855 | |
856 | INSTALL |
857 | README |
858 | |
859 | Edit the previous delta file to change the C<NAME> from C<perldelta> |
860 | to C<perlNNNdelta>. |
861 | |
862 | These two lists of files probably aren't exhaustive; do a recursive grep |
863 | on the previous filename to look for suitable candidates that may have |
864 | been missed. |
865 | |
866 | Finally, commit: |
867 | |
868 | $ git commit -a -m 'create perlXXXdelta' |
869 | |
870 | At this point you may want to compare the commit with a previous bump to |
871 | see if they look similar. See commit ca8de22071 for an example of a |
872 | previous version bump. |

898 | Copy the perlNNNdelta.pod for this release into the other branches; for |
899 | example: |

900 | |
75a012fe |
901 | $ cp -i ../5.10.x/pod/perl5101delta.pod pod/ # for example |
902 | $ git add pod/perl5101delta.pod |
903 | |
904 | Edit F<pod.lst> to add an entry for the file, e.g.: |
905 | |
906 | perl5101delta Perl changes in version 5.10.1 |
907 | |
908 | Then rebuild various files: |
7277a900 |
909 | |
75a012fe |
910 | $ perl pod/buildtoc --build-all |
911 | |
912 | Finally, commit: |
