pathutil: use util.pathto() to calculate relative cwd in canonpath() os.path.relpath() exploded if the 'root' and 'cwd' directories had different drive letters. I noticed this in TortoiseHg when typing a fileset into the filter, and it kept complaining until the closing '()' was typed. This was reproducible on the command line with: $ cd /d $ hg -R /c/Users/Matt/Projects/hg files 'set:e' Traceback (most recent call last): ... File "mercurial\pathutil.pyc", line 182, in canonpath File "ntpath.pyc", line 529, in relpath ValueError: path is on drive c:, start on drive d:

Added signature for changeset 0ccb43d4cf01

Added tag 4.4 for changeset 0ccb43d4cf01

test-dispatch: stabilize the test When cwd is removed and `hg` is executed, some shells may run `getcwd` before forking and executing, some may not do it, some may print a different error message. The test should be shell-independent so let's just avoid checking the error message. Differential Revision: https://phab.mercurial-scm.org/D1282

internals: update test-help.t for config registrar copy-edit

internals: copy-edit "register" -> "registrar" in configitem docs

merge with i18n

i18n-pt_BR: synchronized with cab34bda259e

help: minor copy editing for grammar

configitems: relax warning about unwanted default value The original condition was a bit harsh for extension authors since third-party extensions need to preserve compatibility with older Mercurial versions, where no defaults would be loaded from the configtable. So let's silence the warning if the given default value matches, which should be harmless.

filemerge: pass a default value to _toolstr (issue5718) After a refactoring, _toolstr stopped having default="" as one of it's args, therefore when called without a default it returns None and not "". This causes concatenation to fail.

children: fix the log expansion of `hg children` in doc `hg log -r children()` returns `hg: parse error: missing argument`. Differential Revision: https://phab.mercurial-scm.org/D1269

test-static-http: flush access log per request It appears that stderr is fully buffered on Windows. # no-check-commit because of log_message() function

statichttprepo: do not use platform path separator to build a URL It wouldn't work between Windows client and Unix server.

merge: disable path conflict checking by default (issue5716) We shouldn't ship a severe perf regression in hg update for 4.4. Differential Revision: https://phab.mercurial-scm.org/D1223

merge: add a config option to disable path conflict checking We've found a severe perf regression in `hg update` caused by the path conflict checking code. The next patch will disable this by default. Differential Revision: https://phab.mercurial-scm.org/D1222

dirstate: clean up when restoring identical backups When a dirstate backup is restored, it is possible that no actual changes to the dirstate have been made. In this case, the backup is still a hardlink to the original dirstate. Unfortunately, `os.rename` silently fails (nothing happens, and no error occurs) when `src` and `dst` are hardlinks to the same file. As a result, the backup is left lying around. Over time, these files accumulate. When restoring dirstate backups, check if the backup and the dirstate are the same file, and if so, just delete the backup.

tests: adjust hooks for Windows I'm not sure why these weren't working on Windows. The failures were generally in the style of: - remote: phase-move: cb9a9f314b8b07ba71012fcdbc544b5a4d82ff5b: 1 -> 0 + remote: "phase-move: $HG_NODE: $HG_OLDPHASE -> $HG_PHASE" and - abort: pretxnclose-bookmark.force-forward hook exited with status 1 - [255] + abort: pretxnclose-bookmark.force-public hook exited with status 255 + [255] These failures originated in ee5f0d047b41::f6d17075608f.

test-log-linerange: open binary file in binary mode The '\n' characters were being translated on Windows, throwing off hg and git hashes, as well as the file content in the diff.

test-arbitraryfilectx: stabilize for Windows Previously, the second last test (context.arbitraryfilectx(..)) returned True on Windows. I changed the repo setup sequence to import a patch, so that way the repo would have a proper symlink. That made the last test fail, since it is comparing files in wdir(), one of which is not the expected symlink. Apparently the (feature !) line matching doesn't work well with (no-eol), so I had to conditionalize the test instead of the output.

dirstate: remove excess attribute lookups for dirstate.status (issue5714) A recent refactor added a layer of abstraction to the dirstate which makes doing things like 'foo in dirstate' now require some extra Python attribute lookups. This is causing a 100ms slow down in hg status for mozilla-central. The fix is to hoist the inner dict's functions onto the main class once the lazy loading it complete, as well as store the actual functions before doing the status loop (as is done for other such functions). In my testing, it seems to address the performance regression, but we'll need to see the perf run results to know for sure. Differential Revision: https://phab.mercurial-scm.org/D1257

dirstate: avoid reading the map when possible (issue5713) (issue5717) Before the recent refactor, we would not load the entire map until it was accessed. As part of the refactor, that got lost and even just trying to load the dirstate parents would load the whole map. This caused a perf regression (issue5713) and a regression with static http serving (issue5717). Making it lazy loaded again fixes both. Differential Revision: https://phab.mercurial-scm.org/D1253

dirstate: move clear onto dirstatemap class A future diff will move the lazy loading aspect of dirstate to the dirstatemap class. This means it requires a slightly different strategy of clearing than just reinstantiating the object (since just reinstantiating the object will lazily load the on disk data again later instead of remaining permanently empty). So let's give it it's own clear function. Differential Revision: https://phab.mercurial-scm.org/D1252

internal-doc: document the config register mechanism This explains the various usage and feature of the config register introduced in Mercurial 4.3 and 4.4.

help: clarify the pre-txnclose-phase documentation Gregory Szorc requested some clarification.

internal-doc: document the 'phases' parameters to 'getbundle' The getbundle wireprotocol method has some extended documentation. We update it with the next parameters introduced for binary phases.

status: update the help to indicate that clean files are not normally tersed The same applies to '?' if --quiet is used (or any of the other states if some of -marduic is specified), but I couldn't figure out how to express that clearly.

terse: split on repo separator instead of os.sep (issue5715) The paths being processed are from scmutil.status, and therefore normalized to '/' separators.

makefile: put format-c into .PHONY targets

statichttprepo: prevent loading dirstate over HTTP on node lookup (issue5717) This seems a bit hacky, but works well. There should be no reason that static-http repo had to load dirstate. Initially I tried to proxy os.stat() call through vfs so that statichttpvfs could hook it, but there wasn't a good error value which the statichttpvfs could return to get around the util.filestat issue.

test-static-http: show all files accessed over HTTP This provides some confidence on files that should be loadable over HTTP. Hopefully it will prevent future bugs.
