largefiles: fix cat for largefiles (issue3352) This is a fix to largefiles so that 'hg cat' will work correctly when a largefile is specified. As per discussion on Issue 3352: 1) The file will be printed regardless if it is binary or large. 2) The file is downloaded if it is not readily available (not found in the system cache), so that it can be printed. If the download fails, then we abort.

pure: quiesce build warnings The following patch fixes the following warning when building pure: package init file 'mercurial/pure/__init__.py' not found (or not a regular file)

util.h: replace ntohl/htonl with get/putbe32

scmutil: fix systemrcpath regression introduced in f5dd179bfa4a Changeset f5dd179bfa4a introduced a 'root' path component to look for hgrc files, which is used both as an absolute path and a path relative to the <install-root>. The latter one was broken since 'root' was set to an absolute location and the subsequent os.path.join discarded the <install-root> path prefix.

revlog: fix partial revision() docstring (from d7d64b89a65c)

graphlog: fix --follow FILE and relative paths The situation is complicated because filelog() revset uses a match object in relpath mode while follow() revset interprets the filename as a manifest entry.

graphlog: reduce duplication in --follow code

graphlog: add all log options to glog command glog and log -G should be equivalent.

graphlog: implement --hidden

revert: add support for reverting subrepos without --no-backup and/or --all When a subrepo is reverted but --no-backup is not set, call revert on the subrepo that is being reverted prior to updating it to the revision specified in the parent repo's .hgsubstate file. The --all flag is passed down to the subrepo when it is being reverted. If the --all flag is not set, all files that are modified on the subrepo will be reverted.

revert: add support for reverting subrepos Reverting a subrepo is done by updating it to the revision that is selected on the parent repo .hgsubstate file. * ISSUES/TODO: - reverting added and removed subrepos is not supported yet. - reverting subrepos is only supported if the --no-backup flag is used (this limitation will be removed on another patch). - The behavior of the --all flag has been changed. It now reverts subrepos as well. Note that this may lead to data loss if the user has a dirty subrepo.

commands: move bundle type validation earlier Checking the bundle type late in the command's execution can mean that we do work for a long time before complaining about incorrect user input and aborting. Guess how I discovered this.

changegroupsubset: optimize function lookup in prune

changegroup: optimize gennodelist

revlog: drop some unneeded rev.node calls in revdiff

revlog: avoid an expensive string copy This showed up in a statprof profile of "hg svn rebuildmeta", which is read-intensive on the changelog. This two-line patch improved the performance of that command by 10%.

changegroupsubset: avoid setdefault in inner loop

changegroupsubset: drop repeated len() calls

changegroup: reduce progress overhead

changegroupsubset: renest inner loop The mdata list should generally be shorter than changedfiles

revlog: increase readahead size

revset: avoid demandimport bug Apparently the "import x as xy" doesn't manage to update xy in the current scope's dictionary after load, which causes nodemod.nullrev to do a huge amount of demandload magic in the inner loop.

mq: replace hasattr() with util.safehasattr(), update check-code.py

parsers: use base-16 trie for faster node->rev mapping This greatly speeds up node->rev lookups, with results that are often user-perceptible: for instance, "hg --time log" of the node associated with rev 1000 on a linux-2.6 repo improves from 0.3 seconds to 0.03. I have not found any instances of slowdowns. The new perfnodelookup command in contrib/perf.py demonstrates the speedup more dramatically, since it performs no I/O. For a single lookup, the new code is about 40x faster. These changes also prepare the ground for the possibility of further improving the performance of prefix-based node lookups.

check-code: avoid false-positive on ++

graphlog: cleanup before code move - Avoid revset module aliasing - Mark makefilematcher() private
