It has -been tested while building packages for the mips64el port and it has proven to -be useful. - -It was written having in mind the experience of `fullpkg`, which converted to -`fullpkg-ng` and then splitted into `fullpkg-build` and `fullpkg-find`. It's -aim is to simplify algorithms implemented on the fullpkg family, while solving -some design issues that made fullpkg miss some packages sometimes. - - -## Requirements - -`treepkg` needs the help of `toru-path` for "indexing" an ABS tree. `toru-path` -stores a tokyocabinet database of "pkgname" => "path" pairs, where pkgname is -replaced by the "pkgbase", "pkgname", and "provides" fields of a PKGBUILD, -followed by the path of the current PKGBUILD. - -This information is then used by `treepkg` to know where to find the PKGBUILD of -a package. The fullpkg family needed to guess this by traversing the full ABS -tree, and therefore it was unable to find pkgnames that differ from pkgbase. - -So, to use `treepkg` you need to run `toru-path` after the ABS tree update. - -> Split PKGBUILDs make it difficult to extract metadata if it's stored inside -> package() functions. This will happen with the provides field and `treepkg` -> won't find that linux-libre-headers provides linux-headers, for instance. - -## How does it work - -`treepkg` must be run from the path of the PKGBUILD you're going to build (this -may change over time). This will be DEPTH=0 and it will create a temporary -directory to work on in the format /tmp/pkgbase-treepkg-random-string. Inside -this directory, it will copy the needed PKGBUILDs prefixed with their depth -number. The first package will always be copied to 000\_pkgbase. - -From then on, treepkg sources the PKGBUILD and runs itself over all pkgnames on -the depends and makedepends array, only if it detects their versions aren't -already built or deprecated by newer ones, using the `is_built` utility. - -While processing this info, it will increase the depth of the packages. It'll -also write a CSV file with the knowledge it acquires from the ABS tree (useful -for debugging). This file is called BUILDORDER. - -When this process ends (no more needed dependencies are found), the temporary -work dir is traversed in inverse order (from higher depths to 0) running the -FULLBUILDCMD from libretools.conf and then the HOOKLOCALRELEASE variable, which -*must* provide a way to `repo-add` the packages to an available repository, so -the next build will find and install the newer version using pacman. - -For instance, having this as the first pacman repository (on /etc/pacman.conf): - - [stage3] - Server = /var/cache/pacman/pkg - -And this on /etc/makepkg.conf: - - PKGDEST=/var/cache/pacman/pkg - -Your HOOKLOCALRELEASE script should look like this: - - # Get needed vars - source /etc/makepkg.conf - source /etc/libretools.conf - source ./PKGBUILD - - unset build package check - - fullver=$(full_version ${epoch:-0} ${pkgver} ${pkgrel}) - pkgs=() - - # Generate canonical package paths - msg "Adding packages to [stage3]..." - for name in ${pkgname[@]}; do - msg2 "${name} ${fullver}" - pkgs+=("${PKGDEST}/${name}-${fullver}-*.pkg.tar.*") - done - - # Add the packages to a local - repo-add ${PKGDEST}/stage3.db.tar.gz ${pkgs[@]} - - # Stage the packages for later releasing - librestage $1 - -> Note the first HOOKLOCALRELEASE argument is the remote repository name (core, -> extra, etc.) - -There's a special case when a dependency depends on another that was put on a -depth level lower than itself. In this case the build order will be wrongly -assumed and you may end up with broken packages. - -To explain it with an example: - - ghostscript (0) - fontconfig (1) - \ cups (1) - fontconfig (ignored) - -The second time fontconfig appears, it will be ignored. In this case cups will -build against an fontconfig version that will be outdated by the fontconfig -version at depth 1. In this cases, `treepkg` will detect it cached the -dependency on a lower depth, and will "bury" it to a depth higher than the -current one. Thus this will become the build path: - - ghostscript (0) - fontconfig (buried) - \ cups (1) - fontconfig (2) - -> Note: currently, `treepkg` doesn't perform recursive burying, so if you hit a -> really long build tree with some circular dependencies you may find packages -> buried several times and queued to build before their actuals deps. - -## Tips - -`treepkg` accepts two arguments: 1) the temporary work dir and 2) the next depth -level it should use (if current equals 0, it'll pass 1). You don't need to pass -this arguments when running it manually, they're used internally to -automatically construct the build path. - -But if a build failed, `treepkg` will cancel itself immediately informing you -where the leftovers files were left. If you pass this path to `treepkg` as the -first argument, it will resume the build, skipping to the last package being -packaged. - -You can take the opportunity given by this to modify the build path or the -PKGBUILDs, without having to run `treepkg` twice. For instance you can remove a -package from the build order, or move it manually, or update the PKGBUILD that -made `treepkg` fail in the first place. You can force a skipped package (after -building it manually) by using `touch built_ok` on the PKGBUILD dir. - -You don't probably want to mess with the second argument though. diff --git a/doc/workflows.md b/doc/workflows.md index 9a8c1a6..03dca4f 100644 --- a/doc/workflows.md +++ b/doc/workflows.md @@ -42,7 +42,9 @@ Workflow: `git log --no-merges --numstat`. * Pick a package and run `treepkg` from its dir on the chroot, or retake a build - with `treepkg /tmp/package-treepkg-xxxx`.
