pager

-----

  $ cat >> fakepager.py <<EOF

  > import sys

  > for line in sys.stdin:

  >     sys.stdout.write('paged! %r\n' % line)

  > EOF

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 ..
