rust-dirstate: rust implementation of dirstatemap
The `dirstatemap` is one of the last building blocks needed to get to a
`dirstate.walk` Rust implementation.
Disclaimer: This change is part of a big (10) series of patches, all of which
started as one big changeset that took a long time to write.
This `dirstatemap` implementation is a compromise in terms of complexity both
for me and for the reviewers. I chose to submit this patch right now because
while it is not perfect, it works and is simple enough (IMHO) to be reviewed.
The Python implementation uses a lot of lazy propertycaches, breaks
encapsulation and is used as an iterator in a lot of places, all of which
dictated the somewhat unidiomatic patterns in this change.
Like written in the comments, rewriting this struct to use the typestate
pattern might be a good idea, but this is a good first step.

Verify that pending changesets are seen by pretxn* hooks but not by other processes that access the destination repo while the hooks are running. The hooks (python and external) both reject changesets after some think time, during which another process runs pull. Each hook creates a file ('notify') to indicate to the controlling process that it is running; the process removes the file to indicate the hook can terminate. init env vars $ d=`pwd` $ maxwait=20 utility to run the test - start a push in the background and run pull $ dotest() { > rm -f notify > printf 'push '; hg -R child-push tip --template '{node}\n' > hg -R child-push -q push > push.out 2>&1 & > > # wait for hook to create the notify file > i=$maxwait > while [ ! -f notify -a $i != 0 ]; do > sleep 1 > i=`expr $i - 1` > done > > # run pull > hg -R child-pull -q pull > rc=$? > > # tell hook to finish; notify should exist. > rm notify > wait > > cat push.out > printf 'pull '; hg -R child-pull tip --template '{node}\n' > return $rc > } python hook $ cat <<EOF > reject.py > import os > import time > def rejecthook(ui, repo, hooktype, node, **opts): > ui.write(b'hook %s\\n' % repo[b'tip'].hex()) > # create the notify file so caller knows we're running > fpath = os.path.join('$d', 'notify') > f = open(fpath, 'w') > f.close() > # wait for ack - caller should delete the notify file > i = int("$maxwait") > while os.path.exists(fpath) and i > 0: > time.sleep(1) > i -= 1 > return True # reject the changesets > EOF external hook $ cat <<EOF > reject.sh > printf 'hook '; hg tip --template '{node}\\n' > # create the notify file so caller knows we're running > fpath=$d/notify > touch \$fpath > # wait for ack - caller should delete the notify file > i=$maxwait > while [ -f \$fpath -a \$i != 0 ]; do > sleep 1 > i=\`expr \$i - 1\` > done > exit 1 # reject the changesets > EOF create repos $ hg init parent $ hg clone -q parent child-push $ hg clone -q parent child-pull $ echo a > child-push/a $ hg -R child-push add child-push/a $ hg -R child-push commit -m a -d '1000000 0' test python hook $ cat <<EOF > parent/.hg/hgrc > [extensions] > reject = $d/reject.py > [hooks] > pretxnchangegroup = python:reject.rejecthook > EOF $ dotest push 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b hook 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b transaction abort! rollback completed abort: pretxnchangegroup hook failed pull 0000000000000000000000000000000000000000 test external hook $ cat <<EOF > parent/.hg/hgrc > [hooks] > pretxnchangegroup = sh $d/reject.sh > EOF $ dotest push 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b hook 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b transaction abort! rollback completed abort: pretxnchangegroup hook exited with status 1 pull 0000000000000000000000000000000000000000 Test that pending on transaction without changegroup see the normal changegroup( (issue4609) $ cat <<EOF > parent/.hg/hgrc > [hooks] > pretxnchangegroup= > pretxnclose = hg tip -T "tip: {node|short}\n" > [phases] > publishing=False > EOF setup $ cd parent $ echo a > a $ hg add a $ hg commit -m a tip: cb9a9f314b8b actual test $ hg phase --public . tip: cb9a9f314b8b
