1=encoding utf8 2 3=head1 NAME 4 5release_managers_guide - Releasing a new version of perl 5.x 6 7Note that things change at each release, so there may be new things not 8covered here, or tools may need updating. 9 10=head1 MAKING A CHECKLIST 11 12If you are preparing to do a release, you can run the 13F<Porting/make-rmg-checklist> script to generate a new version of this 14document that starts with a checklist for your release. 15 16This script is run as: 17 18 perl Porting/make-rmg-checklist \ 19 --version [5.x.y-RC#] > /tmp/rmg.pod 20 21You can also pass the C<--html> flag to generate an HTML document instead of 22POD. 23 24 perl Porting/make-rmg-checklist --html \ 25 --version [5.x.y-RC#] > /tmp/rmg.html 26 27=head1 SYNOPSIS 28 29This document describes the series of tasks required - some automatic, some 30manual - to produce a perl release of some description, be that a release 31candidate, or final, numbered release of maint or blead. 32 33The release process has traditionally been executed by the current 34pumpking. Blead releases from 5.11.0 forward are made each month on the 3520th by a non-pumpking release engineer. The release engineer roster 36and schedule can be found in Porting/release_schedule.pod. 37 38This document both helps as a check-list for the release engineer 39and is a base for ideas on how the various tasks could be automated 40or distributed. 41 42The checklist of a typical release cycle is as follows: 43 44 (5.10.1 is released, and post-release actions have been done) 45 46 ...time passes... 47 48 a few weeks before the release, a number of steps are performed, 49 including bumping the version to 5.10.2 50 51 ...a few weeks pass... 52 53 perl-5.10.2-RC1 is released 54 55 perl-5.10.2 is released 56 57 post-release actions are performed, including creating new 58 perldelta.pod 59 60 ... the cycle continues ... 61 62=head1 DETAILS 63 64Some of the tasks described below apply to all four types of 65release of Perl. (blead, RC, final release of maint, final 66release of blead). Some of these tasks apply only to a subset 67of these release types. If a step does not apply to a given 68type of release, you will see a notation to that effect at 69the beginning of the step. 70 71=head2 Release types 72 73=over 4 74 75=item Release Candidate (RC) 76 77A release candidate is an attempt to produce a tarball that is a close as 78possible to the final release. Indeed, unless critical faults are found 79during the RC testing, the final release will be identical to the RC 80barring a few minor fixups (updating the release date in F<perlhist.pod>, 81removing the RC status from F<patchlevel.h>, etc). If faults are found, 82then the fixes should be put into a new release candidate, never directly 83into a final release. 84 85 86=item Stable/Maint release (MAINT). 87 88A release with an even version number, and subversion number > 0, such as 895.14.1 or 5.14.2. 90 91At this point you should have a working release candidate with few or no 92changes since. 93 94It's essentially the same procedure as for making a release candidate, but 95with a whole bunch of extra post-release steps. 96 97Note that for a maint release there are two versions of this guide to 98consider: the one in the maint branch, and the one in blead. Which one to 99use is a fine judgement. The blead one will be most up-to-date, while 100it might describe some steps or new tools that aren't applicable to older 101maint branches. It is probably best to review both versions of this 102document, but to most closely follow the steps in the maint version. 103 104=item A blead point release (BLEAD-POINT) 105 106A release with an odd version number, such as 5.15.0 or 5.15.1. 107 108This isn't for production, so it has less stability requirements than for 109other release types, and isn't preceded by RC releases. Other than that, 110it is similar to a MAINT release. 111 112=item Blead final release (BLEAD-FINAL) 113 114A release with an even version number, and subversion number == 0, such as 1155.14.0. That is to say, it's the big new release once per year. 116 117It's essentially the same procedure as for making a release candidate, but 118with a whole bunch of extra post-release steps, even more than for MAINT. 119 120=back 121 122=for checklist begin 123 124=head2 Prerequisites 125 126Before you can make an official release of perl, there are a few 127hoops you need to jump through: 128 129=head3 PAUSE account with pumpkin status 130 131Make sure you have a PAUSE account suitable for uploading a perl release. 132If you don't have a PAUSE account, then request one: 133 134 https://pause.perl.org/pause/query?ACTION=request_id 135 136Check that your account is allowed to upload perl distros: go to 137L<https://pause.perl.org/pause/authenquery?ACTION=who_pumpkin> and check that 138your PAUSE ID is listed there. If not, ask Andreas KE<0xf6>nig to add your ID 139to the list of people allowed to upload something called perl. You can find 140Andreas' email address at: 141 142 https://pause.perl.org/pause/query?ACTION=pause_04imprint 143 144=head3 rt.perl.org update access 145 146Make sure you have permission to close tickets on L<http://rt.perl.org/> 147so you can respond to bug reports as necessary during your stint. If you 148don't, make an account (if you don't have one) and contact the pumpking 149with your username to get ticket-closing permission. 150 151=head3 git checkout and commit bit 152 153You will need a working C<git> installation, checkout of the perl 154git repository and perl commit bit. For information about working 155with perl and git, see F<pod/perlgit.pod>. 156 157If you are not yet a perl committer, you won't be able to make a 158release. Have a chat with whichever evil perl porter tried to talk 159you into the idea in the first place to figure out the best way to 160resolve the issue. 161 162=head3 web-based file share 163 164You will need to be able to share tarballs with #p5p members for 165pre-release testing, and you may wish to upload to PAUSE via URL. 166Make sure you have a way of sharing files, such as a web server or 167file-sharing service. 168 169Porters have access to the "dromedary" server (users.perl5.git.perl.org), 170which has a F<public_html> directory to share files with. 171(L<http://users.perl5.git.perl.org/~username/perl-5.xx.y.tar.gz>) 172 173If you use Dropbox, you can append "raw=1" as a parameter to their usual 174sharing link to allow direct download (albeit with redirects). 175 176=head3 Quotation for release announcement epigraph 177 178You will need a quotation to use as an epigraph to your release announcement. 179It will live forever (along with Perl), so make it a good one. 180 181=head3 Install the previous version of perl 182 183During the testing phase of the release you have created, you will be 184asked to compare the installed files with a previous install. Save yourself 185some time on release day, and have a (clean) install of the previous 186version ready. 187 188=head2 Building a release - advance actions 189 190The work of building a release candidate for an even numbered release 191(BLEAD-FINAL) of perl generally starts several weeks before the first 192release candidate. Some of the following steps should be done regularly, 193but all I<must> be done in the run up to a release. 194 195=head3 dual-life CPAN module synchronisation 196 197To see which core distro versions differ from the current CPAN versions: 198 199 $ ./perl -Ilib Porting/core-cpan-diff -x -a 200 201However, this only checks whether the version recorded in 202F<Porting/Maintainers.pl> differs from the latest on CPAN. It doesn't tell you 203if the code itself has diverged from CPAN. 204 205You can also run an actual diff of the contents of the modules, comparing core 206to CPAN, to ensure that there were no erroneous/extraneous changes that need to 207be dealt with. You do this by not passing the C<-x> option: 208 209 $ ./perl -Ilib Porting/core-cpan-diff -a -o ~/corediffs 210 211Passing C<-u cpan> will probably be helpful, since it limits the search to 212distributions with 'cpan' upstream source. (It's OK for blead upstream to 213differ from CPAN because those dual-life releases usually come I<after> perl 214is released.) 215 216See also the C<-d> and C<-v> options for more detail (and the C<-u> option as 217mentioned above). You'll probably want to use the C<-c cachedir> option to 218avoid repeated CPAN downloads and may want to use C<-m file:///mirror/path> if 219you made a local CPAN mirror. Note that a minicpan mirror won't actually work, 220but can provide a good first pass to quickly get a list of modules which 221definitely haven't changed, to avoid having to download absolutely everything. 222 223For a BLEAD-POINT or BLEAD-FINAL release with 'cpan' upstream, if a CPAN 224release appears to be ahead of blead, then consider updating it (or asking the 225relevant porter to do so). (However, if this is a BLEAD-FINAL release or one of 226the last BLEAD-POINT releases before it and hence blead is in some kind of 227"code freeze" state (e.g. the sequence might be "contentious changes freeze", 228then "user-visible changes freeze" and finally "full code freeze") then any 229CPAN module updates must be subject to the same restrictions, so it may not be 230possible to update all modules until after the BLEAD-FINAL release.) If blead 231contains edits to a 'cpan' upstream module, this is naughty but sometimes 232unavoidable to keep blead tests passing. Make sure the affected file has a 233CUSTOMIZED entry in F<Porting/Maintainers.pl>. 234 235If you are making a MAINT release, run C<core-cpan-diff> on both blead and 236maint, then diff the two outputs. Compare this with what you expect, and if 237necessary, fix things up. For example, you might think that both blead 238and maint are synchronised with a particular CPAN module, but one might 239have some extra changes. 240 241In any case, any cpan-first distribution that is listed as having files 242"Customized for blead" in the output of cpan-core-diff should have requests 243submitted to the maintainer(s) to make a cpan release to catch up with blead. 244 245Additionally, all files listed as "modified" but not "customized for blead" 246should have entries added under the C<CUSTOMIZED> key in 247F<Porting/Maintainers.pl>, as well as checksums updated via: 248 249 cd t; ./perl -I../lib porting/customized.t --regen 250 251=head4 Sync CPAN modules with the corresponding cpanE<sol> distro 252 253In most cases, once a new version of a distribution shipped with core has been 254uploaded to CPAN, the core version thereof can be synchronized automatically 255with the program F<Porting/sync-with-cpan>. (But see the comments at the 256beginning of that program. In particular, it has not yet been exercised on 257Windows as much as it has on Unix-like platforms.) 258 259If, however, F<Porting/sync-with-cpan> does not provide good results, follow 260the steps below. 261 262=over 4 263 264=item * 265 266Fetch the most recent version from CPAN. 267 268=item * 269 270Unpack the retrieved tarball. Rename the old directory; rename the new 271directory to the original name. 272 273=item * 274 275Restore any F<.gitignore> file. This can be done by issuing 276C<git checkout .gitignore> in the F<cpan/Distro> directory. 277 278=item * 279 280Remove files we do not need. That is, remove any files that match the 281entries in C<@IGNORABLE> in F<Porting/Maintainers.pl>, and anything that 282matches the C<EXCLUDED> section of the distro's entry in the C<%Modules> 283hash. 284 285=item * 286 287Restore any files mentioned in the C<CUSTOMIZED> section, using 288C<git checkout>. Make any new customizations if necessary. Also, 289restore any files that are mentioned in C<@IGNORE>, but were checked 290into the repository anyway. 291 292=item * 293 294For any new files in the distro, determine whether they are needed. 295If not, delete them, and list them in either C<EXCLUDED> or C<@IGNORABLE>. 296Otherwise, add them to C<MANIFEST>, and run C<git add> to add the files 297to the repository. 298 299=item * 300 301For any files that are gone, remove them from C<MANIFEST>, and use 302C<git rm> to tell git the files will be gone. 303 304=item * 305 306If the C<MANIFEST> file was changed in any of the previous steps, run 307C<perl Porting/manisort --output MANIFEST.sort; mv MANIFEST.sort MANIFEST>. 308 309=item * 310 311For any files that have an execute bit set, either remove the execute 312bit, or edit F<Porting/exec-bit.txt> 313 314=item * 315 316Run C<make> (or C<nmake> on Windows), see if C<perl> compiles. 317 318=item * 319 320Run the tests for the package. 321 322=item * 323 324Run the tests in F<t/porting> (C<make test_porting>). 325 326=item * 327 328Update the C<DISTRIBUTION> entry in F<Porting/Maintainers.pl>. 329 330=item * 331 332Run a full configure/build/test cycle. 333 334=item * 335 336If everything is ok, commit the changes. 337 338=back 339 340For entries with a non-simple C<FILES> section, or with a C<MAP>, you 341may have to take more steps than listed above. 342 343=head3 Ensure dual-life CPAN module stability 344 345This comes down to: 346 347 for each module that fails its regression tests on $current 348 did it fail identically on $previous? 349 if yes, "SEP" (Somebody Else's Problem, but try to make sure a 350 bug ticket is filed) 351 else work out why it failed (a bisect is useful for this) 352 353 attempt to group failure causes 354 355 for each failure cause 356 is that a regression? 357 if yes, figure out how to fix it 358 (more code? revert the code that broke it) 359 else 360 (presumably) it's relying on something un-or-under-documented 361 should the existing behaviour stay? 362 yes - goto "regression" 363 no - note it in perldelta as a significant bugfix 364 (also, try to inform the module's author) 365 366=head3 monitor smoke tests for failures 367 368Similarly, monitor the smoking of core tests, and try to fix. See 369L<https://tux.nl/perl5/smoke/index.html>, L<http://perl5.test-smoke.org/> 370and L<http://perl.develop-help.com> for a summary. See also 371L<http://www.nntp.perl.org/group/perl.daily-build.reports/> which has 372the raw reports. 373 374Similarly, monitor the smoking of perl for compiler warnings, and try to 375fix. 376 377=for checklist skip BLEAD-POINT 378 379=head3 monitor CPAN testers for failures 380 381For any release except a BLEAD-POINT: Examine the relevant analysis report(s) 382at L<http://analysis.cpantesters.org/beforemaintrelease> to see how the 383impending release is performing compared to previous releases with 384regard to building and testing CPAN modules. 385 386That page accepts a query parameter, C<pair> that takes a pair of 387colon-delimited versions to use for comparison. For example: 388 389L<http://analysis.cpantesters.org/beforemaintrelease?pair=5.20.2:5.22.0%20RC1> 390 391=head3 update perldelta 392 393Get perldelta in a mostly finished state. 394 395Read F<Porting/how_to_write_a_perldelta.pod>, and try to make sure that 396every section it lists is, if necessary, populated and complete. Copy 397edit the whole document. 398 399You won't be able to automatically fill in the "Updated Modules" section until 400after Module::CoreList is updated (as described below in 401L<"update Module::CoreList">). 402 403=head3 Bump the version number 404 405Do not do this yet for a BLEAD-POINT release! You will do this at the end of 406the release process (after building the final tarball, tagging etc). 407 408Increase the version number (e.g. from 5.12.0 to 5.12.1). 409 410For a release candidate for a stable perl, this should happen a week or two 411before the first release candidate to allow sufficient time for testing and 412smoking with the target version built into the perl executable. For 413subsequent release candidates and the final release, it is not necessary to 414bump the version further. 415 416There is a tool to semi-automate this process: 417 418 $ ./perl -Ilib Porting/bump-perl-version -i 5.10.0 5.10.1 419 420Remember that this tool is largely just grepping for '5.10.0' or whatever, 421so it will generate false positives. Be careful not change text like 422"this was fixed in 5.10.0"! 423 424Use git status and git diff to select changes you want to keep. 425 426Be particularly careful with F<INSTALL>, which contains a mixture of 427C<5.10.0>-type strings, some of which need bumping on every release, and 428some of which need to be left unchanged. 429See below in L<"update INSTALL"> for more details. 430 431For the first RC release leading up to a BLEAD-FINAL release, update the 432description of which releases are now "officially" supported in 433F<pod/perlpolicy.pod>. 434 435When doing a BLEAD-POINT or BLEAD-FINAL release, also make sure the 436C<PERL_API_*> constants in F<patchlevel.h> are in sync with the version 437you're releasing, unless you're absolutely sure the release you're about to 438make is 100% binary compatible to an earlier release. Note: for BLEAD-POINT 439releases the bump should have already occured at the end of the previous release 440and this is somethig you would have to do at the very end. 441When releasing a MAINT perl version, the C<PERL_API_*> constants C<MUST NOT> 442be changed as we aim to guarantee binary compatibility in maint branches. 443 444After editing, regenerate uconfig.h (this must be run on a system with a 445/bin/sh available): 446 447 $ perl regen/uconfig_h.pl 448 449This might not cause any new changes. 450 451You may also need to regen opcodes: 452 453 $ ./perl -Ilib regen/opcode.pl 454 455Test your changes: 456 457 $ git clean -xdf # careful if you don't have local files to keep! 458 $ ./Configure -des -Dusedevel 459 $ make 460 $ make test 461 462Do note that at this stage, porting tests will fail. They will continue 463to fail until you've updated Module::CoreList, as described below. 464 465Commit your changes: 466 467 $ git status 468 $ git diff 469 B<review the delta carefully> 470 471 $ git commit -a -m 'Bump the perl version in various places for 5.x.y' 472 473At this point you may want to compare the commit with a previous bump to 474see if they look similar. See commit f7cf42bb69 for an example of a 475previous version bump. 476 477When the version number is bumped, you should also update Module::CoreList 478(as described below in L<"update Module::CoreList">) to reflect the new 479version number. 480 481=head3 update INSTALL 482 483Review and update INSTALL to account for the change in version number. 484INSTALL for a BLEAD-POINT release should already contain the expected version. 485The lines in F<INSTALL> about "is not binary compatible with" may require a 486correct choice of earlier version to declare incompatibility with. These are 487in the "Changes and Incompatibilities" and "Coexistence with earlier versions 488of perl 5" sections. 489 490Be particularly careful with the section "Upgrading from 5.X.Y or earlier". 491The "X.Y" needs to be changed to the most recent version that we are 492I<not> binary compatible with. 493 494For MAINT and BLEAD-FINAL releases, this needs to refer to the last 495release in the previous development cycle (so for example, for a 5.14.x 496release, this would be 5.13.11). 497 498For BLEAD-POINT releases, it needs to refer to the previous BLEAD-POINT 499release (so for 5.15.3 this would be 5.15.2). If the last release manager 500followed instructions, this should have already been done after the last 501blead release, so you may find nothing to do here. 502 503=head3 Check copyright years 504 505Check that the copyright years are up to date by running: 506 507 $ pushd t; ./perl -I../lib porting/copyright.t --now 508 509Remedy any test failures by editing README or perl.c accordingly (search for 510the "Copyright"). If updating perl.c, check if the file's own copyright date in 511the C comment at the top needs updating, as well as the one printed by C<-v>. 512 513=head3 Check more build configurations 514 515Try running the full test suite against multiple Perl configurations. Here are 516some sets of Configure flags you can try: 517 518=over 4 519 520=item * 521 522C<-Duseshrplib -Dusesitecustomize> 523 524=item * 525 526C<-Duserelocatableinc> 527 528=item * 529 530C<-Dusethreads> 531 532=back 533 534If you have multiple compilers on your machine, you might also consider 535compiling with C<-Dcc=$other_compiler>. 536 537You can also consider pushing the repo to GitHub where Travis CI is enabled 538which would smoke different flavors of Perl for you. 539 540=head3 update perlport 541 542L<perlport> has a section currently named I<Supported Platforms> that 543indicates which platforms are known to build in the current release. 544If necessary update the list and the indicated version number. 545 546=head3 check a readonly build 547 548Even before other prep work, follow the steps in L<build the tarball> and test 549it locally. Because a perl source tarballs sets many files read-only, it could 550test differently than tests run from the repository. After you're sure 551permissions aren't a problem, delete the generated directory and tarballs. 552 553 554=head2 Building a release - on the day 555 556This section describes the actions required to make a release 557that are performed near to, or on the actual release day. 558 559=head3 re-check earlier actions 560 561Review all the actions in the previous section, 562L<"Building a release - advance actions"> to ensure they are all done and 563up-to-date. 564 565=head3 create a release branch 566 567For BLEAD-POINT releases, making a release from a release branch avoids the 568need to freeze blead during the release. This is less important for 569BLEAD-FINAL, MAINT, and RC releases, since blead will already be frozen in 570those cases. Create the branch by running 571 572 git checkout -b release-5.xx.yy 573 574=head3 build a clean perl 575 576Make sure you have a gitwise-clean perl directory (no modified files, 577unpushed commits etc): 578 579 $ git status 580 $ git clean -dxf 581 582then configure and build perl so that you have a Makefile and porting tools: 583 584 $ ./Configure -Dusedevel -des && make 585 586=head3 Check module versions 587 588For each Perl release since the previous release of the current branch, check 589for modules that have identical version numbers but different contents by 590running: 591 592 $ ./perl -Ilib Porting/cmpVERSION.pl --tag=v5.X.YY 593 594(This is done automatically by F<t/porting/cmp_version.t> for the previous 595release of the current branch, but not for any releases from other branches.) 596 597Any modules that fail will need a version bump, plus a nudge to the upstream 598maintainer for 'cpan' upstream modules. 599 600=head3 update Module::CoreList 601 602=head4 Bump Module::CoreList* $VERSIONs 603 604If necessary, bump C<$VERSION> (there's no need to do this 605for every RC; in RC1, bump the version to a new clean number that will 606appear in the final release, and leave as-is for the later RCs and final). 607It may also happen that C<Module::CoreList> has been modified in blead, and 608hence has a new version number already. (But make sure it is not the same 609number as a CPAN release.) 610 611C<$Module::CoreList::Utils::VERSION> should always be equal to 612C<$Module::CoreList::VERSION>.

XXX need a better example 635 636[ Note that the procedure for handling Module::CoreList in maint branches 637is a bit complex, and the RMG currently don't describe a full and 638workable approach. The main issue is keeping Module::CoreList 639and its version number synchronised across all maint branches, blead and 640CPAN, while having to bump its version number for every RC release. 641See this brief p5p thread: 642 643 Message-ID: <20130311174402.GZ2294@iabyn.com> 644 645If you can devise a workable system, feel free to try it out, and to 646update the RMG accordingly! 647 648DAPM May 2013 ] 649 650F<corelist.pl> uses ftp.funet.fi to verify information about dual-lived 651modules on CPAN.

They can be removed using: 763 764 $ git rm <file1> <file2> ... 765 766For example, for RC0 of 5.16.0: 767 768 $ cd pod 769 $ git rm perldelta515*.pod 770 771=for checklist skip BLEAD-FINAL BLEAD-POINT 772 773=head3 add recent perldeltas 774 775For the first RC for a MAINT release, copy in any recent perldeltas from 776blead that have been added since the last release on this branch. This 777should include any recent maint releases on branches older than your one, 778but not newer. For example if you're producing a 5.14.x release, copy any 779perldeltas from recent 5.10.x, 5.12.x etc maint releases, but not from 7805.16.x or higher. Remember to 781 782 $ git add <file1> <file2> ... 783 784=head3 update and commit perldelta files 785 786If you have added or removed any perldelta files via the previous two 787steps, then edit F<pod/perl.pod> to add/remove them from its table of 788contents, then run F<Porting/pod_rules.pl> to propagate your changes there 789into all the other files that mention them (including F<MANIFEST>). You'll 790need to C<git add> the files that it changes. 791 792Then build a clean perl and do a full test 793 794 $ git status 795 $ git clean -dxf 796 $ ./Configure -Dusedevel -des 797 $ make 798 $ make test 799 800Once all tests pass, commit your changes. 801 802=head3 final check of perldelta placeholders 803 804Check for any 'XXX' leftover section in the perldelta. 805Either fill them or remove these sections appropriately. 806 807 $ git grep XX pod/perldelta.pod 808 809=head3 build a clean perl 810 811If you skipped the previous step (adding/removing perldeltas), 812again, make sure you have a gitwise-clean perl directory (no modified files, 813unpushed commits etc): 814 815 $ git status 816 $ git clean -dxf 817 818then configure and build perl so that you have a Makefile and porting tools: 819 820 $ ./Configure -Dusedevel -des && make 821 822=for checklist skip BLEAD-FINAL BLEAD-POINT 823 824=head3 synchronise from blead's perlhist.pod 825 826For the first RC for a MAINT release, copy in the latest 827F<pod/perlhist.pod> from blead; this will include details of newer 828releases in all branches. In theory, blead's version should be a strict 829superset of the one in this branch, but it's probably safest to examine the 830changes first, to ensure that there's nothing in this branch that was 831forgotten from blead. An easy way to do that is with C<< git checkout -p >>, 832to selectively apply any changes from the blead version to your current 833branch: 834 835 $ git fetch origin 836 $ git checkout -p origin/blead pod/perlhist.pod 837 $ git commit -m 'sync perlhist from blead' pod/perlhist.pod 838 839=head3 update perlhist.pod 840 841Add an entry to F<pod/perlhist.pod> with the release date, e.g.: 842 843 David 5.10.1 2009-Aug-06 844 845List yourself in the left-hand column, and if this is the first release 846that you've ever done, make sure that your name is listed in the section 847entitled C<THE KEEPERS OF THE PUMPKIN>. 848 849I<If you're making a BLEAD-FINAL release>, also update the "SELECTED 850RELEASE SIZES" section with the output of 851F<Porting/perlhist_calculate.pl>. 852 853Be sure to commit your changes: 854 855 $ git commit -m 'add new release to perlhist' pod/perlhist.pod 856 857=for checklist skip BLEAD-POINT 858 859=head3 update patchlevel.h 860 861I<You MUST SKIP this step for a BLEAD-POINT release> 862 863Update F<patchlevel.h> to add a C<-RC1>-or-whatever string; or, if this is 864a final release, remove it.

Note that as they have been built from a git working 902directory, they will still identify themselves using git tags and 903commits. (Note that for an odd-numbered version, perl will install 904itself as C<perl5.x.y>). C<perl -v> will identify itself as: 905 906 This is perl 5, version X, subversion Y (v5.X.Y (v5.X.Z-NNN-gdeadbeef)) 907 908where 5.X.Z is the latest tag, NNN the number of commits since this tag, 909and C<< deadbeef >> commit of that tag. 910 911Then delete the temporary installation. 912 913=head3 create the release tag 914 915Create the tag identifying this release (e.g.): 916 917 $ git tag v5.11.0 -m "First release of the v5.11 series!" 918 919It is B<VERY> important that from this point forward, you not push 920your git changes to the Perl master repository. If anything goes 921wrong before you publish your newly-created tag, you can delete 922and recreate it. Once you push your tag, we're stuck with it 923and you'll need to use a new version number for your release. 924 925=head3 build the tarball 926 927Before you run the following, you might want to install 7-Zip (the 928C<p7zip-full> package under Debian or the C<p7zip> port on MacPorts) or 929the AdvanceCOMP suite (e.g. the C<advancecomp> package under Debian, 930or the C<advancecomp> port on macports - 7-Zip on Windows is the 931same code as AdvanceCOMP, so Windows users get the smallest files 932first time). These compress about 5% smaller than gzip and bzip2. 933Over the lifetime of your distribution this will save a lot of 934people a small amount of download time and disk space, which adds 935up. 936 937In order to produce the C<xz> tarball, XZ Utils are required. The C<xz> 938utility is included with most modern UNIX-type operating systems and 939is available for Cygwin. A Windows port is available from 940L<http://tukaani.org/xz/>. 941 942B<IMPORTANT>: if you are on OS X, you must export C<COPYFILE_DISABLE=1> 943to prevent OS X resource files from being included in your tarball. After 944creating the tarball following the instructions below, inspect it to ensure 945you don't have files like F<._foobar>. 946 947Create a tarball. Use the C<-s> option to specify a suitable suffix for 948the tarball and directory name: 949 950 $ cd root/of/perl/tree 951 $ make distclean # make sure distclean works 952 $ git clean -xdf # make sure perl and git agree on files 953 # git clean should not output anything! 954 $ git status --ignored # and there's nothing lying around 955 956 $ perl Porting/makerel -x -s RC1 # for a release candidate 957 $ perl Porting/makerel -x # for the release itself 958 959This creates the directory F<../perl-x.y.z-RC1> or similar, copies all 960the MANIFEST files into it, sets the correct permissions on them, then 961tars it up as F<../perl-x.y.z-RC1.tar.gz>. The C<-x> also produces a 962C<tar.xz> file. 963 964If you're getting your tarball suffixed with -uncommitted and you're sure 965your changes were all committed, you can override the suffix with: 966 967 $ perl Porting/makerel -x -s '' 968 969XXX if we go for extra tags and branches stuff, then add the extra details 970here 971 972Finally, clean up the temporary directory, e.g. 973 974 $ rm -rf ../perl-x.y.z-RC1 975 976=head3 test the tarball 977 978Once you have a tarball it's time to test the tarball (not the repository). 979 980=head4 Copy the tarball to a web server 981 982Copy the tarballs (.gz and .xz) to a web server somewhere you have access to. 983 984=head4 Download the tarball to another machine and unpack it 985 986Download the tarball to some other machine. For a release candidate, 987you really want to test your tarball on two or more different platforms 988and architectures. 989 990=head4 Ask #p5p to test the tarball on different platforms 991 992Once you've verified the tarball can be downloaded and unpacked, 993ask the #p5p IRC channel on irc.perl.org for volunteers to test the 994tarballs on whatever platforms they can. 995 996If you're not confident in the tarball, you can defer this step until after 997your own tarball testing, below. 998 999=head4 Check that F<Configure> works 1000 1001Check that basic configuration and tests work on each test machine: 1002 1003 $ ./Configure -des && make all minitest test 1004 1005 # Or for a development release: 1006 $ ./Configure -Dusedevel -des && make all minitest test 1007 1008=head4 Run the test harness and install 1009 1010Check that the test harness and install work on each test machine: 1011 1012 $ make distclean 1013 $ ./Configure -des -Dprefix=/install/path && make all test_harness install 1014 $ cd /install/path 1015 1016=head4 Check C<perl -v> and C<perl -V> 1017 1018Check that the output of C<perl -v> and C<perl -V> are as expected, 1019especially as regards version numbers, patch and/or RC levels, and @INC 1020paths. 1021 1022Note that the results may be different without a F<.git/> directory, 1023which is why you should test from the tarball. 1024 1025=head4 Run the Installation Verification Procedure utility 1026 1027 $ ./perl ./perlivp 1028 # Or, perhaps: 1029 $ ./perl5.x.y ./perlivp5.x.y 1030 ... 1031 All tests successful. 1032 $ 1033 1034=head4 Compare the installed paths to the last release 1035 1036Compare the pathnames of all installed files with those of the previous 1037release (i.e. against the last installed tarball on this branch which you 1038have previously verified using this same procedure). In particular, look 1039for files in the wrong place, or files no longer included which should be. 1040For example, suppose the about-to-be-released version is 5.10.1 and the 1041previous is 5.10.0: 1042 1043 cd installdir-5.10.0/ 1044 find . -type f | perl -pe's/5\.10\.0/5.10.1/g' | sort > /tmp/f1 1045 cd installdir-5.10.1/ 1046 find . -type f | sort > /tmp/f2 1047 diff -u /tmp/f[12] 1048 1049=head4 Bootstrap the CPAN client 1050 1051Bootstrap the CPAN client on the clean install: 1052 1053 $ bin/cpan 1054 1055 # Or, perhaps: 1056 $ bin/cpan5.xx.x 1057 1058=head4 Install the Inline module with CPAN and test it 1059 1060If you're using C<local::lib>, you should reset your environment before 1061performing these actions: 1062 1063 $ unset PERL5LIB PERL_MB_OPT PERL_LOCAL_LIB_ROOT PERL_MM_OPT 1064 1065Try installing a popular CPAN module that's reasonably complex and that 1066has dependencies; for example: 1067 1068 CPAN> install Inline::C 1069 CPAN> quit 1070 1071Check that your perl can run this: 1072 1073 $ bin/perl -lwe "use Inline C => q[int f() { return 42;}]; print f" 1074 42 1075 $ 1076 1077=head4 Make sure that perlbug works 1078 1079Test L<perlbug> with the following: 1080 1081 $ bin/perlbug 1082 ... 1083 Subject: test bug report 1084 Local perl administrator [yourself]: 1085 Editor [vi]: 1086 Module: 1087 Category [core]: 1088 Severity [low]: 1089 (edit report) 1090 Action (Send/Display/Edit/Subject/Save to File): f 1091 Name of file to save message in [perlbug.rep]: 1092 Action (Send/Display/Edit/Subject/Save to File): Q 1093 1094and carefully examine the output (in F<perlbug.rep]>), especially 1095the "Locally applied patches" section. If everything appears okay, then 1096delete the file, and try it again, this time actually submitting the bug 1097report. Check that it shows up, then remember to close it! 1098 1099=for checklist skip BLEAD-POINT 1100 1101=head3 monitor smokes 1102 1103XXX This is probably irrelevant if working on a release branch, though 1104MAINT or RC might want to push a smoke branch and wait. 1105 1106Wait for the smoke tests to catch up with the commit which this release is 1107based on (or at least the last commit of any consequence). 1108 1109Then check that the smoke tests pass (particularly on Win32). If not, go 1110back and fix things. 1111 1112Note that for I<BLEAD-POINT> releases this may not be practical. It takes a 1113long time for the smokers to catch up, especially the Win32 1114smokers. This is why we have a RC cycle for I<MAINT> and I<BLEAD-FINAL> 1115releases, but for I<BLEAD-POINT> releases sometimes the best you can do is 1116to plead with people on IRC to test stuff on their platforms, fire away, 1117and then hope for the best. 1118 1119=head3 upload to PAUSE 1120 1121Once smoking is okay, upload it to PAUSE. This is the point of no return. 1122If anything goes wrong after this point, you will need to re-prepare 1123a new release with a new minor version or RC number. 1124 1125 https://pause.perl.org/ 1126 1127(Log in, then select 'Upload a file to CPAN') 1128 1129If your workstation is not connected to a high-bandwidth, 1130high-reliability connection to the Internet, you should probably use the 1131"GET URL" feature (rather than "HTTP UPLOAD") to have PAUSE retrieve the 1132new release from wherever you put it for testers to find it.

(The opposite problem -- trying to figure out why there 1333*is* a bug in something calling itself 5.20.1 when in fact the bug was 1334introduced later -- shouldn't arise for MAINT releases since they should, 1335in theory, only contain bug fixes but never regressions.)) 1336 1337=head3 clean build and test 1338 1339Run a clean build and test to make sure nothing obvious is broken. 1340 1341In particular, F<Porting/perldelta_template.pod> is intentionally exempted 1342from podchecker tests, to avoid false positives about placeholder text. 1343However, once it's copied to F<pod/perldelta.pod> the contents can now 1344cause test failures.
