largefiles: handle merges between normal files and largefiles (
issue3084)
The largefiles extension prevents users from adding a normal file
named 'foo' if there is already a largefile with the same name.
However, there was a loop-hole: when merging, it was possible to bring
in a normal file named 'foo' while also having a '.hglf/foo' file.
This patch fixes this by extending the manifest merge to deal with
these kinds of conflicts. If there is a normal file 'foo' in the
working copy, and the other parent brings in a '.hglf/foo' file, then
the user will be prompted to keep the normal file or the largefile.
Likewise for the symmetric case where a normal file is brought in via
the second parent. The prompt looks like this:
$ hg merge
foo has been turned into a largefile
use (l)argefile or keep as (n)ormal file?
After the merge, either the '.hglf/foo' file or the 'foo' file will
have been deleted. This would cause status to return output like:
$ hg status
M foo
R foo
To fix this, the lfiles_repo.status method is changed so that a
removed normal file isn't shown if there is largefile with the same
name, and vice versa for largefiles.
progress: check for ui.quiet and ui.debugflag before we write
ui.quiet and ui.debugflag are not initialized during uisetup and
reposetup. progressui is always initialized, therefore we have to check
during write() if ui.quiet is set or not.
changelog: handle decoding of NULs in extra more carefully (
issue3156)
Escaped NULs adjacent to [0-7] could be decoded as octal. This hits
about 0.24% of changesets with transplant, which stores binary nodes.
