This document collects information about successfully releasing LLVM
|
|
|
|
|
(including subprojects llvm-gcc and Clang) to the public.
|
|
|
|
|
It is the release manager's responsibility to ensure that a high quality
|
2007-09-28 22:50:54 +00:00
|
|
|
build of LLVM is released.

<p>LLVM is released on a time based schedule (currently every 6 months). We
|
|
|
|
|
do not have dot releases because of the nature of LLVM incremental
|
|
|
|
|
developement philosophy. The release schedule is roughly as follows:

|
<li>Set code freeze and branch creation date for 6 months after last code freeze
|
2007-09-28 22:50:54 +00:00
|
|
|
date. Announce release schedule to the LLVM community and update the website.</li>
|
|
|
|

<li>Create release branch and begin release process. </li>
|
|
|
|
|
<li>Send out pre-release for first round of testing. Testing will last 7-10 days.
|
|
|
|
|
During the first round of testing, regressions should be found and fixed. Patches
|
|
|
|
|
are merged from mainline to the release branch.</li>
|
|
|
|
|
<li>Generate and send out second pre-release. Bugs found during this time will
|
|
|
|
|
not be fixed unless absolutely critical. Bugs introduce by patches merged in
|
|
|
|
|
will be fixed and if so, a 3rd round of testing is needed.</li>
|
|
|

|
<li>The release notes should be updated during the first and second round of

This section describes a few administrative tasks that need to be done for the
|
|
|
|
|
release process to begin. Specifically, it involves creating the release branch,
|
|
|
|
|
resetting version numbers, and creating the release tarballs for the release
|
|
|
|
|
team to begin testing.

After creating the LLVM release branch, update the release branches'
|
2007-07-23 04:41:42 +00:00
|
|
|
autoconf/configure.ac version from X.Xsvn to just X.X. Update it on mainline

2007-09-28 22:50:54 +00:00
|
|

as well to be the next version (X.X+1svn). Regenerated the configure script

2009-08-19 23:07:37 +00:00

for both. This must be done for both <tt>llvm</tt> and the

A release is qualified when it has no regressions from the previous

|
|
|
|
release (or baseline). Regressions are related to correctness only and not
|
|
|
|
|
performance at this time. <b>Regressions are new failures in the set of tests that
|
2009-08-23 04:36:30 +00:00
|
|
|
are used to qualify each product and only include things on the list.
|
|
|
|
|
Ultimately, there is no end to the number of possible bugs in a release. We
|
|
|
|
|
need a very concrete and definitive release criteria that ensures we have
|
|
|
|
|
monotonically improving quality on some metric. The metric we use is

described below. This doesn't mean that we don't care about other things,

but this are things that must be satisfied before a release can go out</b>

tar balls may be put on the website and the LLVM community is notified. Ask that

|
<li>Download llvm-X.X, llvm-test-X.X, and the appropriate llvm-gcc4
|
|
|
|
|
and/or clang binary. Build LLVM.
|
|
|
|
|
Run "make check" and the full llvm-test suite (make TEST=nightly report).</li>
|

|
|
|
<li>Download llvm-X.X, llvm-test-X.X, and the llvm-gcc4 and/or clang source.
|

Compile everything. Run "make check" and the full llvm-test suite (make TEST=nightly

2007-09-28 22:50:54 +00:00

report).</li>

|
<p>Ask LLVM developers to submit the report and make check results to the list.
|
2009-08-19 23:07:37 +00:00
|
|
|
Attempt to verify that there are no regressions from the previous release.
|
|
|
|
|
The results are not used to qualify a release, but to spot other potential
|
|

|
problems. For unsupported targets, verify that make check at least is
|

|
|
|
clean.</p>

fixes previously merged in have not created new major problems. This is not

<p>FIXME: Add a note if anything needs to be done to the clang website.

Eventually the websites will be merged hopefully.</p>

Review the documentation and ensure that it is up to date. The Release Notes
|
|
|
|
|
must be updated to reflect bug fixes, new known issues, and changes in the
|
|
|
|
|
list of supported platforms. The Getting Started Guide should be updated to
|
|
|
|
|
reflect the new release version number tag avaiable from Subversion and
|
|
|
|
|
changes in basic system requirements. Merge both changes from mainline into
|
|
|
|
|
the release branch.
