receive-pack: new config receive.procReceiveRefs
Add a new multi-valued config variable "receive.procReceiveRefs" for `receive-pack` command, like the follows: git config --system --add receive.procReceiveRefs refs/for git config --system --add receive.procReceiveRefs refs/drafts If the specific prefix strings given by the config variables match the reference names of the commands which are sent from git client to `receive-pack`, these commands will be executed by an external hook (named "proc-receive"), instead of the internal `execute_commands` function. For example, if it is set to "refs/for", pushing to a reference such as "refs/for/master" will not create or update reference "refs/for/master", but may create or update a pull request directly by running the hook "proc-receive". Optional modifiers can be provided in the beginning of the value to filter commands for specific actions: create (a), modify (m), delete (d). A `!` can be included in the modifiers to negate the reference prefix entry. E.g.: git config --system --add receive.procReceiveRefs ad:refs/heads git config --system --add receive.procReceiveRefs !:refs/heads Signed-off-by: Jiang Xin <zhiyou.jx@alibaba-inc.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

receive.procReceiveRefs::
118+
This is a multi-valued variable that defines reference prefixes
119+
to match the commands in `receive-pack`. Commands matching the
120+
prefixes will be executed by an external hook "proc-receive",
121+
instead of the internal `execute_commands` function. If this
122+
variable is not defined, the "proc-receive" hook will never be
123+
used, and all commands will be executed by the internal
124+
`execute_commands` function.
125+
+
126+
For example, if this variable is set to "refs/for", pushing to reference
127+
such as "refs/for/master" will not create or update a reference named
128+
"refs/for/master", but may create or update a pull request directly by
129+
running the hook "proc-receive".
130+
+
131+
Optional modifiers can be provided in the beginning of the value to filter
132+
commands for specific actions: create (a), modify (m), delete (d).
133+
A `!` can be included in the modifiers to negate the reference prefix entry.
134+
E.g.:
135+

136+
git config --system --add receive.procReceiveRefs ad:refs/heads
137+
git config --system --add receive.procReceiveRefs !:refs/heads

receive.updateServerInfo::

If set to true, git-receive-pack will run git-update-server-info

after receiving data from git-push and updating refs.
