matcher: fix issues regex flag contained in pattern (issue6759)

Python 3.11 is now enforcing that flag must be at the beginning of the regex

This creates a serious regression for people using Python 3.11 with an hgignore
using flag in a "relre" pattern.

We now detect any flags in such pattern and "prepend" our ".*" pattern after them.

In addition, we now insert the flag in the regexp to only affect the pattern we
are rewriting. Otherwise, the regex built from the combined pattern would these
flags in the middle of it anyway.

As a side effect of this last change, we fix a bug… before this change regex
flag in a pattern would affect all combined patterns. That was bad and is not
longer the case.

The Rust code needs to be updated to fix that very bug, but we will do it in
another changeset.

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 > $TESTTMP/wait-output.sh << EOF
  > #!/bin/sh
  > set -eu
  > "$RUNTESTDIR/testlib/wait-on-file" 10 "$TESTTMP/wait-for-touched"
  > touch "$TESTTMP/touched"
  > EOF
  $ chmod +x $TESTTMP/wait-output.sh

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > logtoprocess=
  > pager=
  > [pager]
  > pager = "$PYTHON" $TESTTMP/fakepager.py
  > [logtoprocess]
  > commandfinish=$TESTTMP/wait-output.sh
  > EOF
  $ hg version -q --pager=always

  $ touch $TESTTMP/wait-for-touched
  $ "$RUNTESTDIR/testlib/wait-on-file" 5 "$TESTTMP/touched"
  $ test -f $TESTTMP/touched && echo "SUCCESS Pager is not waiting on ltp" || echo "FAIL Pager is waiting on ltp"
