This hook can be used to prevent 'forced' update on certain refs by
making sure that the object name is a commit object that is a
descendant of the commit object named by the old object name.
-That is, to enforce a "fast forward only" policy.
+That is, to enforce a "fast-forward only" policy.
It could also be used to log the old..new status. However, it
does not know the entire set of branches, so it would end up
'git-send-pack' on the other end, so you can simply `echo` messages
for the user.
- post-upload-pack
- ----------------
-
- After upload-pack successfully finishes its operation, this hook is called
- for logging purposes.
-
- The hook is passed various pieces of information, one per line, from its
- standard input. Currently the following items can be fed to the hook, but
- more types of information may be added in the future:
-
- want SHA-1::
- 40-byte hexadecimal object name the client asked to include in the
- resulting pack. Can occur one or more times in the input.
-
- have SHA-1::
- 40-byte hexadecimal object name the client asked to exclude from
- the resulting pack, claiming to have them already. Can occur zero
- or more times in the input.
-
- time float::
- Number of seconds spent for creating the packfile.
-
- size decimal::
- Size of the resulting packfile in bytes.
-
- kind string:
- Either "clone" (when the client did not give us any "have", and asked
- for all our refs with "want"), or "fetch" (otherwise).
