We've made chg utilize the common code path implemented in pager.py (by e8fb65f5e551 and e97133c7a9dc), but the chg server does not always start with a tty. Because of this, uisetup() of the pager extension could be skipped on the chg server. Kudos given to Sean Farley for dogfooding new chg and spotting this problem.

enable pager extension globally, but spawns the master server with no tty:
|
|
|
|
$ chg init pager
|
|
$ cd pager
|
|
$ cat >> $HGRCPATH <<EOF
|
|
> [extensions]
|
|
> pager =
|
|
> [pager]
|
|
> pager = python $TESTTMP/fakepager.py
|
|
> EOF
|
|
$ chg version > /dev/null
|
|
$ touch foo
|
|
$ chg ci -qAm foo
|
|
|
|
pager should be enabled if the attached client has a tty:
|
|
|
|
$ chg log -l1 -q --config ui.formatted=True
|
|
paged! '0:1f7b0de80e11\n'
|
|
$ chg log -l1 -q --config ui.formatted=False
|
|
0:1f7b0de80e11
|
|
|
|
$ cd ..
|

|
|
server lifecycle
|
|
----------------
|
|
|
|
chg server should be restarted on code change, and old server will shut down
|
|
automatically. In this test, we use the following time parameters:
|
|
|
|
- "sleep 1" to make mtime different
|
|
- "sleep 2" to notice mtime change (polling interval is 1 sec)
|
|
|
|
set up repository with an extension:
|
|
|
|
$ chg init extreload
|
|
$ cd extreload
|
|
$ touch dummyext.py
|
|
$ cat <<EOF >> .hg/hgrc
|
|
> [extensions]
|
|
> dummyext = dummyext.py
|
|
> EOF
|
|
|
|
isolate socket directory for stable result:
|
|
|
|
$ OLDCHGSOCKNAME=$CHGSOCKNAME
|
|
$ mkdir chgsock
|
|
$ CHGSOCKNAME=`pwd`/chgsock/server
|
|
|
|
warm up server:
|
|
|
|
$ CHGDEBUG= chg log 2>&1 | egrep 'instruction|start'
|
|
chg: debug: start cmdserver at $TESTTMP/extreload/chgsock/server.* (glob)
|
|
|
|
new server should be started if extension modified:
|
|
|
|
$ sleep 1
|
|
$ touch dummyext.py
|
|
$ CHGDEBUG= chg log 2>&1 | egrep 'instruction|start'
|
|
chg: debug: instruction: unlink $TESTTMP/extreload/chgsock/server-* (glob)
|
|
chg: debug: instruction: reconnect
|
|
chg: debug: start cmdserver at $TESTTMP/extreload/chgsock/server.* (glob)
|
|
|
|
old server will shut down, while new server should still be reachable:
|
|
|
|
$ sleep 2
|
|
$ CHGDEBUG= chg log 2>&1 | (egrep 'instruction|start' || true)
|
|
|
|
socket file should never be unlinked by old server:
|
|
(simulates unowned socket by updating mtime, which makes sure server exits
|
|
at polling cycle)
|
|
|
|
$ ls chgsock/server-*
|
|
chgsock/server-* (glob)
|
|
$ touch chgsock/server-*
|
|
$ sleep 2
|
|
$ ls chgsock/server-*
|
|
chgsock/server-* (glob)
|
|
|
|
since no server is reachable from socket file, new server should be started:
|
|
(this test makes sure that old server shut down automatically)
|
|
|
|
$ CHGDEBUG= chg log 2>&1 | egrep 'instruction|start'
|
|
chg: debug: start cmdserver at $TESTTMP/extreload/chgsock/server.* (glob)
|
|
|
|
shut down servers and restore environment:
|
|
|
|
$ rm -R chgsock
|
|
$ CHGSOCKNAME=$OLDCHGSOCKNAME
|
|
$ cd ..
