py-mercurial: update to 4.4.

Mercurial 4.4 (2017-11-01)

1.1. Notable changes

1.1.1. Control whitespace settings for annotation on hgweb

/annotate URLs on hgweb now accept query string arguments to influence how \ 
whitespace changes impact results.

The arguments "ignorews," "ignorewsamount," \ 
"ignorewseol," and "ignoreblanklines" now have the same \ 
meaning as their [annotate] config section counterparts. Any provided setting \ 
overrides the server default.

HTML checkboxes have been added to the paper and gitweb themes to expose current \ 
whitespace settings and to easily modify the current view.

1.1.2. Fast, heuristic copy-tracing

A new fast heuristic algorithm for copytracing which assumes that the files \ 
moves are either:

    renames in the same directory
    moves in other directories with same names

You can use this algorithm by setting 'experimental.copytrace=heuristics'. This \ 
setting performs full copytracing if both source and destination branches \ 
contains non-public changesets only.

1.1.3. Other changes

    Estimated time is more accurate with non-linear progress
    "hg status -v" can now show unfinished state. For example, when in \ 
an unfinished rebase state, "hg status -v" might show:

     # The repository is in an unfinished *rebase* state.
     # No unresolved merge conflicts.
     # To continue:                hg rebase --continue
     # To abort:                   hg rebase --abort

    Added '--ignore-space-at-eol' diff option to ignore whitespace differences \ 
at line endings.
    show: use consistent node length in views
    show: decrease minimum displayed hash length from 5 to 4
    A new uncommit extension which provides 'hg uncommit' using which one can \ 
uncommit part or all of the changeset. This command undoes the effect of a local \ 
commit, returning the affected files to their uncommitted state.
    'hg clone --uncompressed' uses clone bundles when possible
    'hg annotate --skip' now prints a '*' on lines with skipped revisions
    New 'commands.update.check' feature to adjust constraints on when 'hg \ 
update' will allow updates with a dirty working copy.

    Add an experimental -L/--line-range FILE,FROMLINE:TOLINE option to 'hg log' \ 
command to follow the history of files by line range. In combination with \ 
-p/--patch option, only diff hunks within specified line range will be \ 
displayed. Feedback, especially on UX aspects, is welcome.
    Print warning when fsmonitor isn't being used on a large repository

1.2. Backwards Compatibility Changes

    The config option for copytrace 'experimental.disablecopytrace' is now \ 
replaced with 'experimental.copytrace' which defaults to 'on'. If you need to \ 
turn off copytracing, add '[experimental] copytrace = off' to your config.
    'hg clone --stream' should now be used instead of --uncompressed. \ 
--uncompressed is marked as deprecated and is an alias for --stream. There is no \ 
schedule for elimination of --uncompressed.
    The 'experimental.updatecheck' name for the new 'commands.update.check' \ 
feature is now deprecated, and will be removed after this release.
    Mercurial subrepositories are now shared instead of cloned when the parent \ 
repository is shared. This prevents dangling subrepository references in the \ 
share source. Previously shared repositories with cloned subrepositories will \ 
continue to function unchanged.
    Push no longer triggers a pushkey hook when updating phases. Use the new \ 
'txnclose-phase' and 'txnclose-phase' hooks instead. (Applies when both server \ 
and client use version 4.4 or above).

1.3. Bug Fixes

    Core rebase algorithm has been rewritten to be more robust (issue5578, issue5630)

    Creating a share of a repository with a Mercurial subrepository will now \ 
share the subrepository (issue5675)

1.4. Performance Improvements

    improved performance when many aliases are defined

1.5. API Changes

1.5.1. remove peer.batch()

Replace with peer.iterbatch().

1.5.2. Other Changes

    @peer.batchable can no longer emit local values
    @peer.batchable functions must now yield exactly 2 values
    Rename attributes on sshpeer to reflect peer API
    peer.peerrepository has been removed. Use repository.peer abstract base \ 
class to represent a peer repository.
    revset.stringset() now takes 'order' as the last argument.
