debugrevlog: cope with empty revlog files
I have no idea where it came from, but my clone of Mercurial has an
empty filelog for `contrib/hgfixes/__init__.py` - it's *valid*, just
contains no nodes. Without this change, debugrevlog crashes with a
zero division error.
largefiles: don't mute and obfuscate http errors when putlfile fails
'unexpected putlfile response: None' when an http error occurs is not very
helpful.
Instead, leave the handling of urllib2.HTTPError exceptions to other layers.
largefiles: test coverage of error handling from putlfile
This reveals a wrong and unhelpful 'unexpected putlfile response'.
largefiles: check hash of files in the store before copying to working dir
If the store somehow got corrupted, users could end up in weird situations that
were very hard to recover from or lead to propagation of the corruption.
Instead, spend the extra time checking the hash when copying to the working
directory. If it doesn't match, emit a warning, and don't put wrong content in
the working directory.
largefiles: test coverage of handling of store corruption
This reveals that update might put a corrupted largefile in the working
directory where it will show up as modified and ready for commit.
ui: support paths.default-push without paths.default set (
issue4914)
This behavior regressed as part of the paths API refactoring. Previous
behavior was to accept "default-push" without "default" defined. Current
behavior aborts with "default repository not configured!." This patch
restores the old behavior and adds test coverage for the scenario, which
was absent before.
bookmarks: don't allow pushing new head for existing mark with -B (
issue4400)
