largefiles: use "ui.configlist()" to get largefiles.patterns configuration current lfconvert implementation uses combination of "ui.config()" and "str.split(' ')" to get largefiles.patterns configuration. but it can not handle multiline configuration in hgrc files correctly. lfconvert should use "ui.configlist()" instead of it, as same as override_add does.

status: support revsets with --change

largefiles: avoid use of uinitialized variable in case of errors

tests: remove unstable debugstate output in test-largefiles.t

largefiles: simplify lfutil.writehash This was unnecessarily verbose: there is no need to unlink the file when we open it for write anyway, and there is no need to check if the file exists after we created it.

largefiles: copy files into .hg/largefiles atomically Copying from the user cache into .hg/largefiles could fail halfway though with a partially written file.

largefiles: write .hg/largefiles/ files atomically Before, it was possible to create a .hg/largefiles/hash file with truncated content, i.e., content where SHA-1(content) != hash This breaks the fundamental invariant in largefiles that the file content for files in .hg/largefiles hash to the filename.

largefiles: add comment about non-atomic working directory When updating the working copy with a normal 'hg update', we also don't use atomic writes.
