APR-util can +only be rebuilt if an APR checkout is present, so a APR-util cannot be +built from source alone. (i.e. the scripts do not handle the case of +cached, fresh APR plus a cached but stale APR-util) + +Travis to Github Actions Migration TODO +--------------------------------------- + +* better path filtering so e.g. CHANGES changes don't trigger CI +* support branch conditionals again (some tests are 2.4.x only, some trunk only) +* make caching work properly for APR + CPAN modules + - this is using the wrong model at the moment + - the cache key needs to be based off (source code, job configuration) + - rather than done on the fly in test/travis_before_linux.sh + - pebble + Rustls builds should also be cached +* turn on failure notifications? +* test across different Ubuntu versions again + - and test against OpenSSL 1.x since we're now ONLY building against 3.x +* update the docs below for testing from PRs/feature branches +* introduce some job ordering rather than having a flat/concurrent + set, if the default "./configure && make && test" works *then* start + jobs doing 200 different variations on ./configure --enable-XXX + i.e. stop burning CPU time for a typo which breaks every job + +TODO list +--------- + +* non-x86 builds +* MacOS build +* Windows build +* clang-on-Linux build +* Use containers for non-Ubuntu-based Linux testing + +Known Failures +-------------- + +Some known failures: + +* prefork, and more rarely non-prefork testing sometimes catches child + segfaults under pool-debug from assert()s in (e.g.) + __pthread_tpp_change_priority where one child is destroying threads + which another is waiting for, or iterating through via + apr_pool_walk_tree(). + + See dev@httpd threads: + msg <5f4abde1b5789_13fde2ecacb40795a1@travis-tasks-5b566d48fc-drkb9.mail> + msg <73060f7b-df7f-ad3c-a9fa-dd666a59b31e@kippdata.de> and + https://bz.apache.org/bugzilla/show_bug.cgi?id=63098 + https://bz.apache.org/bugzilla/show_bug.cgi?id=46185 + + Not clear if there is a real bug here which can be reproduced + outside of pool-debug. + +Testing from a Feature Branch [*** N/A FOR GITHUB ACTIONS ***] +----------------------------- + +An SVN branch off trunk should be mirrored to github, and will be +tested in the same way that trunk is in CI, so this workflow is +available for those familiar with using Subversion and the standard +ASF/httpd repository layout. + +Tested branches are listed at: https://travis-ci.com/github/apache/httpd/branches + +Travis will also run the tests for a PR filed against the httpd Github +repository at https://github.com/apache/httpd or from a fork of this +repository if enabled for the Travis user. + +A workflow to enable testing would be as follows, substituting +$USERNAME for your github username: + + $ git clone https://github.com/apache/httpd + $ cd httpd + $ git remote add $USERNAME git@github.com:$USERNAME/httpd.git + $ git checkout -b my-feature origin/trunk + ... do some work ... + $ git commit ... + $ git push -u $USERNAME my-feature:my-feature + +To enable testing for a fork, visit the settings page at +https://travis-ci.com/$USERNAME/httpd/settings - you may need to sync +your account via https://travis-ci.com/account/repositories for a +freshly created fork. + +To create a Pull Request, go to the URL produced in the "git push" +command output when pushing to your fork, which is something like: +https://github.com/apache/httpd/compare/trunk...$USERNAME:trunk + +Once a PR has been created, travis will run the tests and link the +results from a PR comment. All tested PRs are listed here: +https://travis-ci.com/github/apache/httpd/pull_requests + +To merge from github back to SVN trunk, create a patch from e.g.: + + $ git diff origin/trunk..my-feature + +and then apply it in SVN. To rebase a feature once trunk has +diverged, from a feature branch run: + + $ git pull + $ git rebase -i origin/trunk + +and follow the standard rebase steps. -- cgit v1.2.3
