1 Here are the steps to follow to create a new cairo release:
3 1) Ensure that there are no local, uncommitted/unspushed
4 modifications. You're probably in a good state if both "git diff
5 HEAD" and "git log master..origin/master" give no output.
7 2) Verify that the code passes "make distcheck"
9 First, make sure you have 'nm' and 'readelf' commands in PATH.
10 this should be Ok with any Linux distro.
12 Running "make distcheck" should result in no warnings or
13 errors and end with a message of the form:
15 ==================================================
16 cairo-X.Y.Z-head archives ready for distribution:
17 cairo-X.Y.Z-head.tar.gz
18 ==================================================
20 (But the tar file isn't actually ready yet, as we still have
21 some more steps to follow).
23 If you get errors about local PLT entries, you get the list of
24 cairo and pixman entries with the error. For each of these, a
25 call to slim_hidden_def and slim_hidden_proto is needed in the
26 cairo or pixman implementation in the style of other similar calls.
28 3) Fill out an entry in the NEWS file
30 Sift through the logs since the last release. This is most
31 easily done with a comand such as:
33 git log --stat X.Y.Z..
35 where X.Y.Z is the previous release version.
37 Summarize major changes briefly in a style similar to other
38 entries in NEWS. Take special care to note any additions in
39 the API. These should be easy to find by noting modifications
40 to .h files in the log command above. And more specifically,
41 the following command will show each patch that has changed a
42 public header file since the given version:
44 find src/ -name '*.h' ! -name '*-private.h' ! -name 'cairoint.h' | \
45 xargs git log -p X.Y.Z.. --
47 4) Increment cairo_version_{minor|micro} and LT_{CURRENT|VERSION|AGE}
50 If there are backward-incompatible changes in the API, stop
51 now and don't release. Go back and fix the API instead. Cairo
52 is intended to remain backwards-compatible as far as API.
54 So cairo_version_major will not be incremented unless we come
55 up with a new versioning scheme to take advantage of it.
57 If there are API additions, then increment cairo_version_minor
58 and reset cairo_version_micro to 0. NOTE: The minor version is
59 only incremented for releases, not for snapshots.
61 Otherwise, (ie. there are only bug fixes), increment
62 cairo_version_micro to the next larger (even) number.
64 Adjust LT_CURRENT, LT_VERSION, and LT_AGE as described in the
65 comments in configure.in.
67 5) Commit the changes to NEWS and configure.in
69 It's especially important to mention the new version number in your
72 6) Run "make release-publish" which will perform the following steps
75 * Generate ChangeLog files out of git repository
76 * Check that ChangeLog files were generated properly
77 * Check that the version number ends with an even micro component
78 * Check that no release exists with the current version
79 * Verify that make distcheck completes successfully
80 * Generate the final tar file
81 * Generate an sha1sum file
82 * Sign the sha1sum using your GPG setup (asks for your GPG password)
83 * scp the three files to appear on http://cairographics.org/releases
84 * Place local copies of the three files in the releases directory
85 * Create a LATEST-package-version file (after deleting any old one)
86 * Tag the entire source tree with a tag of the form X.Y.Z, and sign
87 the tag with your GPG key (asks for your GPG password, and you
88 may need to set GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL to match
89 your public-key's setting or this fails.)
90 * Provide some text for the release announcement (see below).
91 If for some reason you lost this message, "make release-publish-message"
94 7) Increment cairo_version_micro to the next larger (odd) number in
95 configure, commit, and push.
97 8) Push the newly created tag out to the central tree with a command
102 9) Edit the cairo bugzilla product and add the new version numbers. Note
103 that you need to add two versions. One for the release/snapshot (with
104 an even micro version), another with the post-release version (with an
107 10) Send a message to cairo-announce@cairographics.org and CC
108 gnome-announce-list@gnome.org, (pr@lwn.net as well for major
109 releases) to announce the new release using the text provided from
110 "make release-publish", adding the excerpt from NEWS, your
111 signature, followed by the standard "What is cairo" and "Where to
112 get more information about cairo" blurbs from README, and finally
113 tacking on the detailed changelog-ish thing that gets mailed out
114 when you push the tag (but not the diffstat thing).
116 11) Edit the cairo wiki to add the announcement to the NEWS page and
117 the front page. (just the parts before your signature).
119 12) For minor releases (no X.Y change), notify desktop-devel-list@gnome.org
120 or update the ExternalDependencies page for the current cycle if you
121 know where it is. Currently it's:
