filemerge: split the logic for finding an external tool to its own function This will be used by extdiff in an subsequent patch.

largefiles: simplify check for lack of path arguments Instead of checking for a partial merge by checking that the matches has no files and no patterns, check that it's not an always-matcher. Except for being shorter, it also catches the rare case of an exact-matcher with no files.

largefiles: shortcircuit status code also for non-matching patterns We currently shortcircuit the checking for large file standins if only patterns of type 'path' are given on the command line. That makes e.g. "hg st 'glob:foo/**'" unnecessarily slow when the only large files are in a sibling directory. Relax the check to be that it is not an always-matcher and that no large files match the patterns given on the command line. Note that before this change, only the latter of the following two would show the status of files in .hglf (since the -I makes match.anypats() true). After this change, they both display the status. This behavior doesn't seem correct, but it would be a separate change to explicitly filter out .hglf even in the shortcircuit case. hg st .hglf/$file hg st .hglf/$file -I .

largefiles: remove confusing 'or None' from predicate The match function that is overriden returns a boolean value, so adding 'or None' is both unnecessary and confusing.

largefiles: drop unnecessary setting of matcher._always In two very similar segments of code, an existing matcher is modified by changing its _files attribute through a map and a filter operation. Neither operation can cause an empty list to become non-empty, so a matcher that always matches can not stop always matching. Drop the setting of the attribute, so we don't unnecessarily prevent the fast paths to be taken where these matchers end up being used.

config: move mergetools configuration from contrib to default configuration The merge tool configuration is an essential part of a good initial user experience. 'make osx' installers and direct 'make' installation did not have merge tool configuration. Now they have. Note: The installer fixes for windows have been done blindly and might require additional changes.

config: introduce "built-in" default configuration settings in default.d This helps providing a more consistent user experience on all platforms and with all packaging. The exact location of default.d depends on how Mercurial is installed and whether it is 'frozen'. The exact location should never be relevant to users and is intentionally not explained in details in the documentation. It will however always be next to the help and templates files. Note that setting HGRCPATH also disables these defaults. I don't know if that should be considered a bug or a feature.

contrib: buildrpm checking of md5 checksums of downloaded Python and Docutils

contrib: update build defaults to latest Python and docutils versions Use Python 2.7.8 and Docutils 0.12 for Makefile.python and buildrpm (CentOS 5 rpms).

spelling: fixes from proofreading of spell checker issues

extdiff: quote user-supplied options passed to shell $ hg extdiff -p cmd -o "name <user@example.com>" resulted in a shell redirection error (due to the less-than sign), rather than passing the single option to cmd. This was due to options not being quoted for passing to the shell, via util.system(). Apply util.shellquote() to each of the user-specified options (-o) to the comparison program before they are concatenated and passed to util.system(). The requested external diff command (-p) and the files/directories being compared are already quoted correctly. The discussion at the time of changeset be98c5ce4022 correctly noted that this course of action breaks whitespace-separated options specified for external diff commands in the configuration. The lower part of the patch corrects this by lexing options read from the configuration file into separate options rather than reading them all into the first option. Update test to cover these conditions. Related changesets (reverse-chronological): - be98c5ce4022 (fix reverted to make configuration file options work) - 453097750fbf (issue fixed but without fix for configuration file)

serve: correct meta variable of --daemon-pipefds option It was changed to lock path at e22695b4472f.

tests: have dumbhttp.py use cmdutil.service() to wait for child to listen() Because the original dumbhttp.py exited without waiting for listen(), several tests could fail with "abort: error: Connection refused" if subsequent hg command is fast enough.

test-revert: remove obsolete comment about known misbehavior It seems like the last known misbehvior that the comment was referring to was dealt with in 2ff28e07d7d6 (revert: properly back up added files with local modification, 2014-08-31).

setdiscovery: limit the size of all sample (issue4411) Further digging on this issue show that the limit on the sample size used in discovery never works for heads. Here is a quote from the code itself: desiredlen = size - len(always) if desiredlen <= 0: # This could be bad if there are very many heads, all unknown to the # server. We're counting on long request support here. The long request support never landed and evolution make the "very many heads, all unknown to the server" case quite common. We implement a simple and stupid hard limit of sample size for all query. This should prevent HTTP 414 error with the current state of the code.

hook: protect commit hooks against stripping of temporary commit (issue4422) History rewriting commands like histedit tend to use temporary commits. They may schedule hook execution on these temporary commits for after the lock has been released. But temporary commits are likely to have been stripped before the lock is released (and the hook run). Hook executed for missing revisions leads to various crashes. We disable hooks execution for revision missing in the repo. This provides a dirty but simple fix to user issues.

mq: do not call [0] on revset The __getitem__ method have been removed. The "first" method is to be used instead. Test have been extended to test this code path.

addset: fix `first` and `last` on sorted addset (issue4426) The lazy sorting were not enforced on addset. This was made visible through MQ.

clone: properly mark branches closed with --uncompressed (issue4428) On streaming clone, we were priming the local branch cache with the remote branchmap, without checking which heads were closed. This fixes an issue introduced in: changeset: 17740:e6067bec18da user: Tomasz Kleczek <tomasz.kleczek@fb.com> date: Wed Oct 03 13:19:53 2012 -0700 summary: branchcache: fetch source branchcache during clone (issue3378) that was exposed in 2.9 by: changeset: 20192:38fad5e76ee8 user: Brodie Rao <brodie@sf.io> date: Mon Sep 16 01:08:29 2013 -0700 summary: branches: simplify with repo.branchmap().iterbranches()

clone: fix copying bookmarks in uncompressed clones (issue4430) ef62c66bee1b broke bookmarks getting copied during uncompressed clones. Since most of the pull logic has been moved into exchange.py, lets just call exchange.pull to fix up the repo with the latest bits after the streaming clone has bootstrapped the repo. This keeps us from having to duplicate the bookmark logic.

revset: don't recreate matcher for every revision The matcher variable 'm' in checkstatus() is reset to None on each call, so the caching of the matcher no longer happens as it was intended. This seems to be a regression in ed7b674824a3 (revset: added lazyset implementation to checkstatus, 2014-01-03). Fix by moving the cached matcher into the enclosing function so it's actually cached across calls. This speeds up hg log -r 'modifies(mercurial/context.py)' >/dev/null from 7.5s to 4s. Also see similar fix in f2aeff8a87b6 (revset: avoid recalculating filesets, 2014-10-22).

transaction: only generate file when we actually close the transaction Before this change, the file were written for every call to `tr.close()` exposing data to reader far too early.

transaction: extract file generation into its own function We extract the code generating files into its own function. We are about to move this code around to fix a bug. We'll need it in a function soon to reuse it for "pending" logic. So we move the code into a function instead of moving it twice.

amend: abort early if no username is configured with evolve enabled (issue4211) Amend will reuse the original username if a new one is not provided with -U, but obsolete.createmarkers() only considers ui.username() for the obsolete marker's metadata. Allowing the metadata field to be spoofed seems to defeat the point of the field in the first place. This covers 'evolve amend' and 'ci --amend' with evolve enabled. Without this, the transaction aborts but the parent changeset is set to -1. The corresponding test will be added to evolve separately.
