Enable the extension

  $ echo "[extensions]" >> $HGRCPATH

  $ echo "pull-logger = $TESTDIR/../contrib/pull_logger.py" >> $HGRCPATH

Check the format of the generated log entries, with a bunch of elements in the

common and heads set

Check the number of entries generated in the log when pulling from multiple

clients at the same time

  $ rm -f server/.hg/pull_log.jsonl

  $ for i in $($TESTDIR/seq.py 32); do

  >   hg clone ssh://user@dummy/server client_$i --rev 0

  > done > /dev/null

  $ for i in $($TESTDIR/seq.py 32); do

  >   hg -R client_$i pull --rev 1 &

  > done > /dev/null

  $ wait

  $ wc -l server/.hg/pull_log.jsonl

  \s*64 .* (re)

Test log rotation when reaching some size threshold

  $ cat >> $HGRCPATH << EOF

  $ rm -f server/.hg/pull_log.jsonl

  $ for i in $($TESTDIR/seq.py 10); do
