lfs: add the ability to disable the usercache
While the usercache is important for real world uses, I've been tripped up more
than a couple of times by it in tests- thinking a file was being downloaded, but
it was simply linked from the local cache. The syntax for setting it is the
same as for setting a null remote endpoint, and like that endpoint, is left
undocumented.
This may or may not be a useful feature in the real world (I'd expect any sane
filesystem to support hardlinks at this point).
#require serve no-reposimplestore
$ cat >> $HGRCPATH <<EOF
> [extensions]
> lfs=
> [lfs]
> url=http://localhost:$HGPORT/.git/info/lfs
> track=all()
> [web]
> push_ssl = False
> allow-push = *
> EOF
Serving LFS files can experimentally be turned off. The long term solution is
to support the 'verify' action in both client and server, so that the server can
tell the client to store files elsewhere.
$ hg init server
$ hg --config "lfs.usercache=$TESTTMP/servercache" \
> --config experimental.lfs.serve=False -R server serve -d \
> -p $HGPORT --pid-file=hg.pid -A $TESTTMP/access.log -E $TESTTMP/errors.log
$ cat hg.pid >> $DAEMON_PIDS
Uploads fail...
$ hg init client
$ echo 'this-is-an-lfs-file' > client/lfs.bin
$ hg -R client ci -Am 'initial commit'
adding lfs.bin
$ hg -R client push http://localhost:$HGPORT

... so do a local push to make the data available. Remove the blob from the
default cache, so it attempts to download.
$ hg --config "lfs.usercache=$TESTTMP/servercache" \
> --config "lfs.url=null://" \
> -R client push -q server
$ rm -rf `hg config lfs.usercache`
