subrepo: add regression test for
issue3870
subrepo: clone of git sub-repository creates incorrect git branch (
issue3870)
Mercurial handles git subrepos by incorrect way.
If the mercurial repo has a git sub-repo and somebody started
a new branch in the subrepo and push it into git, the next one
who will clone the whole repo will get incorrect branch name in the git
subrepo.
dispatch: print 'abort:' when a pre-command hook fails (BC)
This also changes the exit code from whatever the hook returned to 255. This
brings it in line with all the other hooks that abort.
largefiles: don't hash all largefiles when initializing a lfdirstate
The largefiles will be hashed on demand if necessary ... and sometimes it isn't
necessary.
largefiles: use filechunkiter for iterating largefile when serving getlfile
The default file iterator is line based and will give odd chunk sizes - often
very short and relatively expensive.
largefiles: stat all largefiles in one batch before downloading
This avoids a lot of expensive roundtrips to remote repositories ... but might
be slightly slower for local operations.
This will also change some aborts on missing files to warnings. That will in
some situations make it possible to continue working on a repository with
missing largefiles.
largefiles: 'put' should store 'source' file in under 'hash', also in localstore
largefiles: getlfile must hit end of HTTP chunked streams to reuse connections
We did read the exactly the right number of bytes from the response body. But
if the response came in chunked encoding then that meant that the HTTP layer
still hadn't read the last 0-sized chunk and expected the app layer to read
more data from the stream. The app layer was however happy and sent another
request which had to be sent on another HTTP connection while the old one was
lingering until some other event closed the connection.
Adding an extra read where we expect to hit the end of file makes the HTTP
connection ready for reuse. This thus plugs a real socket leak.
To distinguish HTTP from SSH we look at self's class, just like it is done in
putlfile.
