Organization of the repository
|
||||||
|
==============================
|
||||||
|
|
||||||
|
The debian package for each LLVM point release is maintained as a git branch.
|
||||||
|
For example, the 4.0 release lives at in the "4.0" branch.
|
||||||
|
|
||||||
|
The current snapshot release is maintained in the "snapshot" branch.
|
||||||
|
|
||||||
|
The easiest way to get all branches is probably to have one
|
||||||
|
clone per version:
|
||||||
|
|
||||||
|
for f in 4.0 5.0 6.0 snapshot; do
|
||||||
|
git clone git@salsa.debian.org:pkg-llvm-team/llvm-toolchain.git -b $f $f
|
||||||
|
done
|
||||||
|
|
||||||
|
Steps for manually building a snapshot release
|
||||||
|
==============================================
|
||||||
|
|
||||||
|
1) Retrieve the latest snapshot and create original tarballs.
|
||||||
|
|
||||||
|
Run the orig-tar.sh script,
|
||||||
|
|
||||||
|
$ sh snapshot/debian/orig-tar.sh
|
||||||
|
|
||||||
|
which will retrieve the latest version for each LLVM subproject (llvm,
|
||||||
|
clang, lldb, etc.) from the main development (upstream SVN). and repack it
|
||||||
|
as a set of tarballs.
|
||||||
|
|
||||||
|
2) Unpack the original tarballs and apply quilt debian patches.
|
||||||
|
|
||||||
|
From the branches/ directory run the unpack.sh script,
|
||||||
|
|
||||||
|
$ sh unpack.sh
|
||||||
|
|
||||||
|
which will unpack the source tree inside a new directory such as
|
||||||
|
branches/llvm-toolchain-snapshot_3.9~svn268942. Depending on the current
|
||||||
|
snapshot version number and svn release, the directory name will be
|
||||||
|
different.
|
||||||
|
|
||||||
|
Quilt patches will then be applied.
|
||||||
|
|
||||||
|
3) Build the binary packages using,
|
||||||
|
|
||||||
|
$ fakeroot debian/rules binary
|
||||||
|
|
||||||
|
When debugging, successive builds can be recompiled faster by using tools such
|
||||||
|
as ccache (PATH=/usr/lib/ccache:$PATH fakeroot debian/rules binary).
|
||||||
|
|
||||||
|
Retrieving a specific branch or release candidate with orig-tar.sh
|
||||||
|
==================================================================
|
||||||
|
|
||||||
|
When using orig-tar.sh, if you need to retrieve a specific branch, you can pass
|
||||||
|
the branch name as the first argument. For example, to get the 4.0 release
|
||||||
|
branch at
|
||||||
|
http://llvm.org/svn/llvm-project/{llvm,...}/branches/release_40
|
||||||
|
you should use,
|
||||||
|
|
||||||
|
$ sh 4.0/debian/orig-tar.sh release_40
|
||||||
|
|
||||||
|
To retrieve a specific release candidate, you can pass the branch name as the
|
||||||
|
first argument, and the tag rc number as the second argument. For example, to
|
||||||
|
get the 4.0.1 release candidate rc3 at
|
||||||
|
http://llvm.org/svn/llvm-project/{llvm,...}/tags/RELEASE_401/rc3
|
||||||
|
you should use,
|
||||||
|
|
||||||
|
$ sh 4.0/debian/orig-tar.sh RELEASE_401 rc3 4.0.1
|
||||||
|
|
||||||
|
Additional maintainer scripts
|
||||||
|
=============================
|
||||||
|
|
||||||
|
The script qualify-clang.sh that is found at the git debian/ directory
|
||||||
|
should be used to quickly test a newly built package. It runs a short
|
||||||
|
set of sanity-check tests and regression tests.
|
||||||
|
|
||||||
|
The script releases/snapshot/debian/prepare-new-release.sh is used when
|
||||||
|
preparing a new point release. It automatically replaces version numbers
|
||||||
|
in various files of the package.
|
||||||
|
|
||||||
|
|
||||||
|
Change in major upstream version
|
||||||
|
================================
|
||||||
|
TODO update with the git commands
|
||||||
|
|
||||||
|
$ svn copy snapshot VERSION
|
||||||
|
$ svn commit -m "VERSION branched" VERSION
|
||||||
|
$ cd VERSION
|
||||||
|
$ sed -i -e '0,/llvm-toolchain-snapshot/s/llvm-toolchain-snapshot/llvm-toolchain-VERSION/' debian/changelog debian/control
|
||||||
|
$ svn commit -m "snapshot => VERSION"
|
||||||
|
$ cd ../snapshot
|
||||||
|
$ emacs debian/prepare-new-release.sh
|
||||||
|
# Change the version
|
||||||
|
$ bash debian/prepare-new-release.sh
|
||||||
|
$ svn commit -m "new snapshot release"
|
||||||
|
|
||||||
|
Now, try build build it.
