In repositories that have accumulated a large number of files over time, the
|
|
|
fncache file is going to be large. If we possibly can avoid loading it, so much the better.
|
|
|
The cache should not loaded when committing changes to existing files, or when unbundling
|
|
|
changesets that only contain changes to existing files:
|
|
|
|
|
|
$ cat > fncacheloadwarn.py << EOF
|
|
|
> from __future__ import absolute_import
|
|
|
> from mercurial import extensions, store
|
|
|
>
|
|
|
> def extsetup(ui):
|
|
|
> def wrapstore(orig, requirements, *args):
|
|
|
> store = orig(requirements, *args)
|
|
|
> if 'store' in requirements and 'fncache' in requirements:
|
|
|
> instrumentfncachestore(store, ui)
|
|
|
> return store
|
|
|
> extensions.wrapfunction(store, 'store', wrapstore)
|
|
|
>
|
|
|
> def instrumentfncachestore(fncachestore, ui):
|
|
|
> class instrumentedfncache(type(fncachestore.fncache)):
|
|
|
> def _load(self):
|
|
|
> ui.warn('fncache load triggered!\n')
|
|
|
> super(instrumentedfncache, self)._load()
|
|
|
> fncachestore.fncache.__class__ = instrumentedfncache
|
|
|
> EOF
|
|
|
|
|
|
$ fncachextpath=`pwd`/fncacheloadwarn.py
|
|
|
$ hg init nofncacheload
|
|
|
$ cd nofncacheload
|
|
|
$ printf "[extensions]\nfncacheloadwarn=$fncachextpath\n" >> .hg/hgrc
|
|
|
|
|
|
A new file should trigger a load, as we'd want to update the fncache set in that case:
|
|
|
|
|
|
$ touch foo
|
|
|
$ hg ci -qAm foo
|
|
|
fncache load triggered!
|
|
|
|
|
|
But modifying that file should not:
|
|
|
|
|
|
$ echo bar >> foo
|
|
|
$ hg ci -qm foo
|
|
|
|
|
|
If a transaction has been aborted, the zero-size truncated index file will
|
|
|
not prevent the fncache from being loaded; rather than actually abort
|
|
|
a transaction, we simulate the situation by creating a zero-size index file:
|
|
|
|
|
|
$ touch .hg/store/data/bar.i
|
|
|
$ touch bar
|
|
|
$ hg ci -qAm bar
|
|
|
fncache load triggered!
|
|
|
|
|
|
Unbundling should follow the same rules; existing files should not cause a load:
|
|
|
|
|
|
$ hg clone -q . tobundle
|
|
|
$ echo 'new line' > tobundle/bar
|
|
|
$ hg -R tobundle ci -qm bar
|
|
|
$ hg -R tobundle bundle -q barupdated.hg
|
|
|
$ hg unbundle -q barupdated.hg
|
|
|
|
|
|
but adding new files should:
|
|
|
|
|
|
$ touch tobundle/newfile
|
|
|
$ hg -R tobundle ci -qAm newfile
|
|
|
$ hg -R tobundle bundle -q newfile.hg
|
|
|
$ hg unbundle -q newfile.hg
|
|
|
fncache load triggered!
