1 HOW TO COMMIT CHANGES TO EMACS

10 (0) Each commit should correspond to a single change (whether spread
11 over multiple files or not). Do not mix different changes in the
12 same commit (eg adding a feature in one file, fixing a bug in
13 another should be two commits, not one).
15 (1) Commit all changed files at once with a single log message (which
16 in CVS will result in an identical log message for all committed
17 files), not one-by-one. This is pretty easy using vc-dir now.
19 (2) Make the log message describe the entire changeset, perhaps
20 including relevant changelog entries (I often don't bother with
21 the latter if it's a trivial sort of change).
23 Many modern source-control systems vaguely distinguish the first
24 line of the log message to use as a short summary for abbreviated
25 history listing (in arch this was explicitly called the summary,
26 but many other systems have a similar concept). So it's nice if
27 you can format the log entry like:
29 SHORTISH ONE-LINE SUMMARY
31 MULTIPLE-LINE DETAILED DESCRIPTION POSSIBLY INCLUDING (OR
32 CONSISTING OF) CHANGELOG ENTRIES
34 [Even with CVS this style is useful, because web CVS browsing
35 interfaces often include the first N words of the log message of
36 the most recent commit as a short "most recent change"
39 (3) Don't phrase log messages assuming the filename is known, because
40 in non-file-oriented systems (everything modern other than CVS),
41 the log listing tends to be treated as global information, and the
42 connection with specific files is less explicit.
44 For instance, currently I often see log messages like "Regenerate";
45 for modern source-control systems with a global log, it's better to
46 have something like "Regenerate configure".
