run-tests: stop ignoring venv-installed packages
This will allow test dependencies to be installed within a venv, instead of
tampering with sys/user sites. One thing to note here is that the `VIRTUAL_ENV`
path takes precedence over system-site, unlike when run directly with an
activated `venv`. For example, `sys.path` as viewed from a feature test in
`hghave.py`, when running `hghave vcr` directly with an activated `venv`:
sys.path: [
'/home/jenkins/hg-committed/tests',
'/usr/lib/python38.zip',
'/usr/lib/python3.8',
'/usr/lib/python3.8/lib-dynload',
'/home/jenkins/test_venv/lib/python3.8/site-packages'
]
vs `sys.path` from the same feature test, when run by `run-tests.py` with this
change:
sys.path: [
'/home/jenkins/hg-committed/tests',
'/home/jenkins/hg-committed',
'/home/jenkins/hg-committed/tests',
'/home/jenkins/test_venv/lib/python3.8/site-packages',
'/usr/lib/python38.zip',
'/usr/lib/python3.8',
'/usr/lib/python3.8/lib-dynload',
'/home/jenkins/.local/lib/python3.8/site-packages',
'/usr/local/lib/python3.8/dist-packages',
'/usr/lib/python3/dist-packages'
]

ATTENTION: logtoprocess runs commands asynchronously. Be sure to append "| cat"
to hg commands, to wait for the output, if you want to test its output.
Otherwise the test will be flaky.
Test if logtoprocess correctly captures command-related log calls.
$ hg init
$ cat > $TESTTMP/foocommand.py << EOF
> from mercurial import registrar
> cmdtable = {}
> command = registrar.command(cmdtable)
> configtable = {}
> configitem = registrar.configitem(configtable)
> configitem(b'logtoprocess', b'foo',
> default=None,
> )
> @command(b'foobar', [])
> def foo(ui, repo):
> ui.log(b'foo', b'a message: %s\n', b'spam')
> EOF
$ cp $HGRCPATH $HGRCPATH.bak
$ cat >> $HGRCPATH << EOF
> [extensions]
> logtoprocess=
> foocommand=$TESTTMP/foocommand.py
> [logtoprocess]
> command=(echo 'logtoprocess command output:';
> echo "\$EVENT";
> echo "\$MSG1") > $TESTTMP/command.log
> commandfinish=(echo 'logtoprocess commandfinish output:';
> echo "\$EVENT";
> echo "\$MSG1";
> echo "canonical: \$OPT_CANONICAL_COMMAND") > $TESTTMP/commandfinish.log
> foo=(echo 'logtoprocess foo output:';
> echo "\$EVENT";
> echo "\$MSG1") > $TESTTMP/foo.log
> EOF
Running a command triggers both a ui.log('command') and a
ui.log('commandfinish') call. The foo command also uses ui.log.
Use sort to avoid ordering issues between the various processes we spawn:
$ hg fooba
$ sleep 1
$ cat $TESTTMP/command.log | sort
command
fooba
logtoprocess command output:
#if no-chg
$ cat $TESTTMP/commandfinish.log | sort
canonical: foobar
commandfinish
fooba exited 0 after * seconds (glob)
logtoprocess commandfinish output:
$ cat $TESTTMP/foo.log | sort
a message: spam
foo
logtoprocess foo output:
#endif
Confirm that logging blocked time catches stdio properly:
$ cp $HGRCPATH.bak $HGRCPATH
$ cat >> $HGRCPATH << EOF
> [extensions]
> logtoprocess=
> pager=
> [logtoprocess]
> uiblocked=echo "\$EVENT stdio \$OPT_STDIO_BLOCKED ms command \$OPT_COMMAND_DURATION ms" > $TESTTMP/uiblocked.log
> [ui]
> logblockedtimes=True
> EOF
$ hg log
$ sleep 1
$ cat $TESTTMP/uiblocked.log
uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)
Try to confirm that pager wait on logtoprocess:
Add a script that waits on a file to appear. If the script is awaited by hg,
the script will die after the timeout before we could touch the file and the
resulting file will not exist. If not, we will touch the file and see it.
$ cat >> fakepager.py <<EOF
> import sys
> printed = False
> for line in sys.stdin:
> sys.stdout.write(line)
> printed = True
> if not printed:
> sys.stdout.write('paged empty output!\n')
> EOF
$ cat > $TESTTMP/wait-output.sh << EOF
