Organization of the repository
|
|
==============================
|
|
|
|
The debian package for each LLVM point release is maintained as a git branch.
|
|
For example, the 10 release lives at in the "10" 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 14 15 snapshot; do
|
|
git clone git@salsa.debian.org:pkg-llvm-team/llvm-toolchain.git -b $f $f
|
|
done
|
|
|
|
debian/control is generated from debian/control.in by running:
|
|
|
|
ebian/rules preconfigure
|
|
|
|
|
|
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 github). 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~+20191018225217+3b123a2be6d.
|
|
(date+hour+short git hash).
|
|
Depending on the current snapshot version number and git 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 10 release
|
|
branch at
|
|
https://github.com/llvm/llvm-project/branches
|
|
you should use,
|
|
|
|
$ sh 10/debian/orig-tar.sh release/10.x
|
|
|
|
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 9.0.1 release candidate rc3 at
|
|
https://github.com/llvm/llvm-project/tags
|
|
you should use,
|
|
|
|
$ sh 10/debian/orig-tar.sh 10.0.1 rc3
|
|
|
|
For a stable release, the syntax is:
|
|
|
|
$ sh 10/debian/orig-tar.sh 10.0.0
|
|
|
|
|
|
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.
|
|
It is executed in autopkgtest.
|
|
|
|
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.
|
|
|
|
Making a change to all versions
|
|
===============================
|
|
|
|
Sometimes, we want to make a change on all branches.
|
|
In that case, start to make the change from the older
|
|
version (example: 8), then, change branch (example: 9) and
|
|
$ git merge origin/8
|
|
to retrieve the changes
|
|
|
|
|
|
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.
