test: stabilize bundle generation for test-sparse-revlog.t

To reduce the instability in the bundle binary content, we force it to contains
delta against p1 in all cases.

In the previous changeset, we already stabilized the processing of the bundle.
So we don't see any output change in the test itself.

#require chg

  $ mkdir log
  $ cp $HGRCPATH $HGRCPATH.unconfigured
  $ cat <<'EOF' >> $HGRCPATH

init repo

  $ chg init foo
  $ cd foo

  $ chg status
  $ echo '=brokenconfig' >> $HGRCPATH
  $ chg status

long socket path

  $ sockpath=$TESTTMP/this/path/should/be/longer/than/one-hundred-and-seven/characters/where/107/is/the/typical/size/limit/of/unix-domain-socket
  $ mkdir -p $sockpath
  $ bakchgsockname=$CHGSOCKNAME
  $ CHGSOCKNAME=$sockpath/server
  $ export CHGSOCKNAME
  $ chg root
  $TESTTMP/foo
  $ rm -rf $sockpath
  $ CHGSOCKNAME=$bakchgsockname
  $ export CHGSOCKNAME

  $ cd ..

editor
------

  $ cat >> pushbuffer.py <<EOF
  > def reposetup(ui, repo):
  >     repo.ui.pushbuffer(subproc=True)
  > EOF

  $ chg init editor
  $ cd editor

by default, system() should be redirected to the client:

  $ touch foo
  $ CHGDEBUG= HGEDITOR=cat chg ci -Am channeled --edit 2>&1 \
  > | egrep "HG:|run 'cat"
  chg: debug: * run 'cat "*"' at '$TESTTMP/editor' (glob)
  HG: Enter commit message.  Lines beginning with 'HG:' are removed.
  HG: Leave message empty to abort commit.
  HG: --
  HG: user: test
  HG: branch 'default'
  HG: added foo

but no redirection should be made if output is captured:

  $ touch bar
  $ CHGDEBUG= HGEDITOR=cat chg ci -Am bufferred --edit \
  > --config extensions.pushbuffer="$TESTTMP/pushbuffer.py" 2>&1 \
  > | egrep "HG:|run 'cat"
  [1]

check that commit commands succeeded:

  $ hg log -T '{rev}:{desc}\n'
  1:bufferred
  0:channeled

  $ cd ..

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

chg waits for pager if runcommand raises

  $ cat > $TESTTMP/crash.py <<EOF
  > from mercurial import registrar
  > cmdtable = {}
  > command = registrar.command(cmdtable)
  > @command(b'crash')
  > def pagercrash(ui, repo, *pats, **opts):
  >     ui.write('going to crash\n')
  >     raise Exception('.')
  > EOF

  $ cat > $TESTTMP/fakepager.py <<EOF
  > from __future__ import absolute_import
  > import sys
  > import time
  > for line in iter(sys.stdin.readline, ''):
  >     if 'crash' in line: # only interested in lines containing 'crash'
  >         # if chg exits when pager is sleeping (incorrectly), the output
  >         # will be captured by the next test case
  >         time.sleep(1)
  >         sys.stdout.write('crash-pager: %s' % line)
  > EOF

  $ cat >> .hg/hgrc <<EOF
  > [extensions]
  > crash = $TESTTMP/crash.py
  > EOF

  $ chg crash --pager=on --config ui.formatted=True 2>/dev/null
  crash-pager: going to crash
  [255]

  $ 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 (glob)
  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
  $ sleep 2
  $ CHGSOCKNAME=$OLDCHGSOCKNAME
  $ cd ..

check that server events are recorded:

  $ ls log
  server.log
  server.log.1

print only the last 10 lines, since we aren't sure how many records are
preserved:

  $ cat log/server.log.1 log/server.log | tail -10 | filterlog
  YYYY/MM/DD HH:MM:SS (PID)> forked worker process (pid=...)
  YYYY/MM/DD HH:MM:SS (PID)> setprocname: ...

  YYYY/MM/DD HH:MM:SS (PID)> worker process exited (pid=...)
  YYYY/MM/DD HH:MM:SS (PID)> $TESTTMP/extreload/chgsock/server-... is not owned, exiting.

repository cache
----------------

  $ rm log/server.log*
  $ cp $HGRCPATH.unconfigured $HGRCPATH
  $ cat <<'EOF' >> $HGRCPATH
  > [cmdserver]
  > log = $TESTTMP/log/server.log
  > max-repo-cache = 1
  > track-log = command, repocache
  > EOF

isolate socket directory for stable result:

  $ OLDCHGSOCKNAME=$CHGSOCKNAME
  $ mkdir chgsock
  $ CHGSOCKNAME=`pwd`/chgsock/server

create empty repo and cache it:

  $ hg init cached
  $ hg id -R cached
  000000000000 tip
  $ sleep 1

modify repo (and cache will be invalidated):

  $ touch cached/a
  $ hg ci -R cached -Am 'add a'
  adding a
  $ sleep 1

read cached repo:

  $ hg log -R cached
  changeset:   0:ac82d8b1f7c4
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     add a
  
  $ sleep 1

discard cached from LRU cache:

  $ hg clone cached cached2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg id -R cached2
  ac82d8b1f7c4 tip
  $ sleep 1

read uncached repo:

  $ hg log -R cached
  changeset:   0:ac82d8b1f7c4
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     add a
  
  $ sleep 1

shut down servers and restore environment:

  $ rm -R chgsock
  $ sleep 2
  $ CHGSOCKNAME=$OLDCHGSOCKNAME

check server log:

  $ cat log/server.log | filterlog
  YYYY/MM/DD HH:MM:SS (PID)> init cached
  YYYY/MM/DD HH:MM:SS (PID)> id -R cached
  YYYY/MM/DD HH:MM:SS (PID)> loaded repo into cache: $TESTTMP/cached (in  ...s)
  YYYY/MM/DD HH:MM:SS (PID)> repo from cache: $TESTTMP/cached
