$ export PYTHONPATH

Check diagnosis, debugging information
|
|
1) Setup configuration
|
|
$ mkcommit() {
|
|
> echo "$1" > "$1"
|
|
> hg add "$1"
|
|
> echo "add $1" > msg
|
|
> echo "" >> msg
|
|
> hg ci -l msg
|
|
> }
|
|
|
|
2) Create a repo with a bunch of revs.
|
|
|
|
$ mkdir concurrency
|
|
$ cd concurrency
|
|
$ hg init
|
|
$ cat >> .hg/hgrc << EOF
|
|
> [extensions]
|
|
> fastmanifest=$TESTDIR/../fastmanifest
|
|
> [fastmanifest]
|
|
> cachecutoffdays=-1
|
|
> cacheonchange=True
|
|
> cacheonchangebackground=True
|
|
> EOF
|
|
$ mkcommit a
|
|
$ mkcommit b
|
|
$ mkcommit c
|
|
$ mkcommit d
|
|
$ mkcommit e

this is a barrier to ensure that any cache workers that we've kicked off
|
|
have completed.
|
|
$ $PYTHON "$TESTDIR/waitforfile.py" --created .hg/store/manifestcache/fast7ab5760d084a24168f7595c38c00f4bbc2e308d9 --deleted .hg/fastmanifest --max-time 1
|
|
$ hg debugcachemanifest --pruneall
|
|
$ hg debugcachemanifest --list
|
|
cache size is: 0 bytes
|
|
number of entries is: 0
|
|
|
|
3) Create a bookmark, triggering a cache fill.
|
|
|
|
$ hg bookmark abc
|
|
this is a barrier to ensure that the cache fill has completed.
|
|
$ $PYTHON "$TESTDIR/waitforfile.py" --created .hg/store/manifestcache/fast7ab5760d084a24168f7595c38c00f4bbc2e308d9 --deleted .hg/fastmanifest --max-time 1
|
|
$ hg debugcachemanifest --list
|
|

|
|
number of entries is: 5

Most relevant cache entries appear first

remove the bookmark to restore the state, but don't cache on change,
|
|
because that could race with the --pruneall.
|
|
$ hg boo -d abc --config=fastmanifest.cacheonchange=False
|
|
$ hg debugcachemanifest --pruneall
|
|
$ hg debugcachemanifest --list
|
|
cache size is: 0 bytes
|
|
number of entries is: 0
|
|
|
|
4) Fake a lock so it looks like another worker is caching entries, and
|
|
trigger a cache fill.
|
|
|
|
$ touch .hg/fastmanifest
|
|
$ hg bookmark abc
|
|
wait one second to ensure that the background worker started up and had a
|
|
chance to try to take the lock.
|
|
$ sleep 1
|
|
$ hg debugcachemanifest --list
|
|
cache size is: 0 bytes
|
|
number of entries is: 0
