Goal of this page
Composing better guidelines for reviewing and classifying commits for the Commit Digest. The source of the original inclusion guidelines can be found here.
On average about 5% of all commits in a week will be included in the commit digest. This means that those who review the commits should choose carefully which commits should be included. To get a feeling for which messages should or should not be included, it could be useful to read existing Commit Digests to see what kind of commits they contain. There is no definitive set of rules when to include a commit message and when not. However, the following gives some guidelines.
Hint: you can always investigate a commit further by clicking on the commit id. This gives you helpful details about which files were modified and allows for a line by line comparison of the source code.
In general add messages to the Commit Digest if they:
- are interesting (in general these messages have a longer text describing them),
- fix a bug (if you’re certain the bug is minor or unimportant you can exclude them), are an optimization or add a feature (for the user); this is in particular the case when there is a "broken box" symbol in the lower right corner of the message,
- new or significantly improved icons.
Generally do not include messages if they:
- are back-ports, i.e., the message basically appears two times (then do not include the backported/branch version, only include the version in trunk),
- are refactorings, internal clean-ups, additions to the API (unless they seem to be interesting, e.g., a whole new API for Nepomuk),
- are about CMake or desktop files, documentation changes (without bug number),
- are about unit tests ( http://en.wikipedia.org/wiki/Unit_testing ),
- are fixes or additions to a localization (without bug number)
- introduce trivial changes such as the resizing of a line-edit or changes in button placement.
- Commits to the http://websvn.kde.org/trunk/kdesupport/emerge/ directory are mostly related to build fixes for KDE on Windows. In general they should not be included unless they are to be judged important based on their description.
- Often you can see commits related to accounts of developers taking place in http://websvn.kde.org/trunk/kde-common/accounts/, these commits should be excluded.
- If work on new icons is being done there can be a high frequency of commits related to them. Only include the most relevant commits stating for example that all 32x32 icons are done or if the last of the icons are committed. A maximum of three of those repeated messages are desirable for a Commit Digest. Because it can be difficult to see in advance if an icon related commit will be the last one for a specific week, the best compromise is to select the last commit in a series of commits related to icons.
- Commits which change the contents of the files called NEWS, AUTHORS, Changelog, README and TODO should be excluded.
- Commits which increase the version number should be excluded.
- Reverts of commits can occur, often because a recent commit introduced a bug. Because the reverted commit was so recent very few people will the existence of the bug, so in general reverts of commits should be excluded unless there is a good reason not to do so.
- Since the migration to Git commits simply mentioning a branch merge (to the master branch, where the code lives that will eventually be released) often occur. These should not be included because they simply fail the criterium that the commit should be interesting.
Bug Fixes: this category contains all commits which mention a bug number in the message. It also contains commits which fix something according to the comment but don't have a bug report attached (these commits need to be important though, remember the 5% rule!).
Optimize: this category is only meant for commits that make things either faster, use less memory, or in rare cases, make the interface more streamlined ("now this can be done in 2 clicks instead of 10").
Other: this category is for commits that don't really fit anywhere else: for example for commits that are really interesting or funny even if they otherwise wouldn't be important (like someone writing in the message that they learned something really important, etc.).
New icons and other new artwork should be classified under the area 'User Interface' and under the type 'Feature'.
