Read on if you are looking to contribute to the project, or are just plain bored.
- production - tried and tested packages promoted from preview by a developer
- preview - contributed packages from trusted ArchAudio members; may also house testing updates for packages in production
- nightly - nightly/daily builds of packages not necessarily tested but whose PKGBUILDs have been verified by a developer; promoted from experimental
- experimental - nightly/daily builds of packages whose PKGBUILDs have been contributed by trusted ArchAudio members
Take a look here.
Anyone and everyone keen on contributing to the buildscripts (PKGBUILDs and related files) can start immediately. You only have to take the time to get in touch with either schivmeister or jonkristian with a password hash. The fastest way is to log on to IRC (#archaudio@Freenode) and look for them, but a more straightforward approach is to simply e-mail them directly:
printf 'schiv#%s.fun\n' archaudio | sed -e 's/#/@/' -e 's/fun/org/' printf 'jon$%s.fun\n' archaudio | sed -e 's/\$/@/' -e 's/fun/org/'
As we mentioned above, this is needed for anyone wanting to have write access to the Subversion repository:
Simply enter a username and password, select either SHA-1 or MD5 (up to you), then click on "encrypt password". The output is what we want.
Or if you prefer an offline method:
htpasswd -cs hashForArchAudio.txt $preferred_username # you need to install 'apache' for this tool
In this example, the file 'hashForArchAudio.txt' will be created with your new password hash. Either send the file itself or copy the hash (the whole line). Don't worry, you're only sharing the cryptographic hash of your password - and not the password itself - so that you can be authenticated.
Simply checkout the repository via HTTPS with your username:
svn co https://svn.archaudio.org/trunk archaudio --username $your_username
You will only have write-access to the preview and experimental repositories, as far as PKGBUILDs and packages are concerned, as well as devel and projects for other things. If you are only concerned about editing PKGBUILDs and nothing else, then you may want to just checkout those specific directories:
svn co https://svn.archaudio.org/trunk/buildscripts archaudio --depth empty --username $your_username cd archaudio svn up preview experimental
Or if you want to be even more specific and work with one repository only:
svn co https://svn.archaudio.org/trunk/buildscripts/$repo_name archaudio --username $your_username
You can also checkout a package directly:
svn co https://svn.archaudio.org/trunk/buildscripts/$repo_name/$pkg_dir --username $your_username
We hope to incorporate these (commands) into a helper script soon.
It is mandatory that you be well-acquainted with Arch Linux packaging before applying to become a (binary) packager. If you maintain packages in AUR you are on the right path.
The only difference here is that you have to do a second, non-recursive checkout for the private packages area, where the binaries are contained and pushed. Although Subversion will not track this directory, we're going to keep it under the main checkout for the sake of consistency. We've already made the necessary amendments so that SVN does not display the '?' symbol as the directory's status.
If you are a 'developer', you have write access to almost everything:
( echo -n 'Username: ' read your_username svn co https://svn.archaudio.org/trunk archaudio --username $your_username cd archaudio svn co https://svn.archaudio.org/trunk/packages --depth empty --username $your_username cd packages svn up production preview --set-depth immediates # nightly/experimental will contain only automated builds ) # if you copy-pasted you have to press ENTER now
If you are a 'packager', your binary-write-access is limited to the preview repository. So, for example, if you are only concerned about editing PKGBUILDs and uploading packages for this repository and nothing else, then it may be less clutter to just do two separate checkouts:
svn co https://svn.archaudio.org/trunk/buildscripts/preview archaudiosrc --username $your_username svn co https://svn.archaudio.org/trunk/packages/preview archaudiobin --depth immediates --username $your_username
So, after having done all that, you would copy the (binary) package that you built to the proper architecture directory, add it to SVN, and finally commit the addition. Optionally, you may clear out the directory again to maintain the 'sparseness':
cp $somewhere/foo-1.1-1-i686.pkg.tar.xz $svn_dir/packages/preview/i686/ svn add $svn_dir/packages/preview/i686/foo-1.1-1-i686.pkg.tar.xz svn ci $svn_dir/packages/preview/i686 -m "Added binary package $package" svn up $vcscopy/packages/preview/i686 --set-depth empty
Old packages will be automatically deleted on the server, so you need not worry about removing them yourself. Be careful to add real binary packages and not symlinks or any other file that may deceive you.
It is recommended to build packages in a chroot environment. To ease up the process you may use the tools like extra-i686-build from the devtools package in Arch Linux's extra repository.
It is best to edit the chroot's pacman.conf so that any ArchAudio-related dependencies can be pulled in. Just run the following anywhere but within a PKGBUILD directory:
extra-i686-build # or x86_64
It will go on to create the chroot, which will by default be located at /var/tmp/archbuild, and then fail upon not finding a PKGBUILD. You can now make your changes to the pristine copy of the chroot (the other copy will be named after your username and will be recreated upon every build from this pristine copy):
If you are on 64-bit, you can build for both architectures:
extra-x86_64-build && extra-i686-build
If you have a powerful machine (anything more than a dual-core), you may want to run each of those builds in two separate windows.
If needed, you may build against the multilib repository, i.e multilib-build.
Unless you know what you are doing, never build against Arch Linux's testing repository, i.e testing-i686-build.
There is a work-in-progress suite of helper scripts called archaudio-devtools, and it is hoped that it will automate most of the labour involved here in a future release.
It is always a good idea to make the following sanity checks a routine:
svn merge --dry-run -r BASE:HEAD . # basically a more intuitive svn stat -u
And if you really cannot find out how to use SVN (man, wiki, google):
svn add $somedir $somefile # to add (recursive)
svn del $somedir $somefile # to delete
Warning: If you remove something without the svn command, Subversion will complain that it is missing since it's not aware of the removal.
svn mv $oldname $newname # same warning applies; you cannot forget the svn before the mv!
svn revert $somedir $somefile # revert some changes (selective)
svn revert -R . # revert ALL changes (recursive)
svn ci -m "$yourmessage" # to finally commit all changes
- Use tools such as namcap and those from to help yourself
- Always ensure a package installs and runs as expected before distributing your changes
- Try to keep in touch with upstream developers of packages you regularly update
- Always check the upstream changelog if an update does not go smoothly
