largefiles: specify unit for ui.progress when operating on files Also make it available for translation. It could already be translated, because it's used as a unit in archival.py and subrepo.py, for example.

templater: make label() just fail if ui object isn't available Silent failure hides bugs and makes it harder to track down the issue. It's worse than raising exception. In future patches, I plan to sort out template functions that require 'ui', 'ctx', 'fctx', etc. so that incompatible functions are excluded and the doc can say in which context these functions are usable. @templatefunc('label', requires=('ui',)) def label(context, mapping, args): ...

convert: fix "stdlib import follows local import" problem in transport Before this patch, import-checker reports error below for importing subversion python binding libraries. stdlib import "svn.*" follows local import: mercurial

convert: fix relative import of stdlib module in subversion Before this patch, import-checker reports "relative import of stdlib module" error for importing Pool and SubversionException from svn.core in subversion.py. To fix this relative import of stdlib module, this patch adds prefix 'svn.core.' to Pool and SubversionException in source. These 'svn.core.' relative accessing shouldn't cause performance impact, because there are much more code paths accessing to 'svn.core.' relative properties. BTW, in transport.py, this error is avoided by assignment below. SubversionException = svn.core.SubversionException But this can't be used in subversion.py case, because: - such assignment in indented code block causes "don't use camelcase in identifiers" error of check-code.py - but it should be placed in indented block, because svn is None at failure of importing subversion python binding libraries (= examination of 'svn' is needed)

convert: make subversion import transport locally Introducing "absolute_import" feature in previous patch caused failure of importing local module "transport".

dockerdeb: add Ubuntu Trusty One problem reported by lintian is "bad-distribution-in-changes-file unstable" in changelog, but the current changelog for the official package in Ubuntu also uses that distribution name (unstable), because they import from Debian. This certainly doesn't stop the build process.

pushoperation: fix language issues in docstring

chg: do not write pidfile Current pidfile logic will only keep the pid of the newest server, which is not very useful if we want to kill all servers, and will become outdated if the server auto exits after being idle for too long. Besides, the server-side pidfile writing logic runs before chgserver gets confighash so it's not trivial to append confighash to pidfile basename like we did for socket file. This patch removes --pidfile from the command starting chgserver and switches to an alternative way (unlink socket file) to stop the server.

chg: remove manual reload logic chgserver now validates and reloads configs automatically. Manually reloading is no longer necessary. Besides, we are deprecating pid files since the server will periodically check its ownership of the socket file and exit if it does not own the socket file any longer, which works more reliable than a pid file. This patch removes the SIGHUP reload logic from both chg server and client.

chg: use --daemon-postexec chdir:/ instead of --cwd / The chgserver is designed to load repo config from current directory. "--cwd /" will prevent chgserver from loading repo config and generate a wrong confighash, which will result in a redirect loop. This patch removes "--cwd /" and uses "--daemon-postexec chdir:/" instead.

serve: add chdir command for --daemon-postexec For chgserver, it probably needs a chdir to /. This patch adds chdir command support for --daemon-postexec so chg client can make use of it.

serve: accept multiple values for --daemon-postexec The next patch will add another postexec command: chdir, which can be used together with unlink. This patch changes the option type of --daemon-postexec from string to list to accept multiple commands. The error message of invalid --daemon-postexec value is also changed to include the actual invalid value.

hgext: officially turn 'hgext' into a namespace package Actually since Python 2.3, there is some way to turn top level package into "namespace package" so that multiple subpackage installed in different part of the path can still be imported transparently. This feature was previously thought (at least by myself) to be only provided by some setuptool black magic. Turning hgext into such namespace package allows third extensions to install themselves inside the "hgext" namespace package to avoid polluting the global python module namespace. They will now be able to do so without making it a pain to use a Mercurial "installed" in a different way/location than these extensions. The only constrains is that the extension ship a 'hgext/__init__.py' containing the same call to 'pkgutil.extend_path' and nothing else. This seems realistic. The main question that remains is: should we introduce a dedicated namespace for third party extension (hgext3rd?) to make a clearer distinction between what is officially supported and what is not? If so, this will be introduced in a follow up patch.

fileset: replace predicate by filesetpredicate of registrar (API) To make all built-in predicates be known to hggettext, loading built-in predicates by loadpredicate() should be placed before fixing i18nfunctions but after all of predicate decorating.

registrar: add filesetpredicate to mark a function as fileset predicate filesetpredicate is used to replace fileset.predicate in subsequent patch. This patch also adds loadpredicate() to fileset, because this combination helps to figure out how the name of "status caller" (or "existing caller") predicate is put into _statuscallers (or _existingcallers). Listing up loadpredicate() in dispatch.extraloaders causes implicit loading fileset predicate functions at loading (3rd party) extension.

registrar: remove useless base classes (API) Previous patches make these classes useless by removing classes derived from them.

revset: remove useless extpredicate class (API) Previous patch makes this classes useless by replacing it with revsetpredicate of registrar. BTW, extpredicate itself has already been broken by that patch, because revsetpredicate of registrar doesn't have compatibility with original predicate (derived from funcregistrar of registrar), in fact.

hook: filter out unstable output in tests This output is different between Python 2.6 and Python 2.7. It's also pretty irrelevant, so just filter it out.

fsmonitor: hook up state-enter, state-leave signals Keeping the codebase in sync with upstream: Watchman 4.4 introduced an advanced settling feature that allows publishing tools to notify subscribing tools of the boundaries for important filesystem operations. https://facebook.github.io/watchman/docs/cmd/subscribe.html#advanced-settling has more information about how this feature works. This diff connects a signal that we're calling `hg.update` to the mercurial update function so that mercurial can indirectly notify tools (such as IDEs or build machinery) when it is changing the working copy. This will allow those tools to pause their normal actions as the files are changing and defer them until the end of the operation. In addition to sending the enter/leave signals for the state, we are able to publish useful metadata along the same channel. In this case we are passing the following pieces of information: 1. destination revision hash 2. An estimate of the distance between the current state and the target state 3. A success indicator. 4. Whether it is a partial update The distance is estimate may be useful to tools that wish to change their strategy after the update has complete. For example, a large update may be efficient to deal with by walking some internal state in the subscriber rather than feeding every individual file notification through its normal (small) delta mechanism. We estimate the distance by comparing the repository revision number. In some cases we cannot come up with a number so we report 0. This is ok; we're offering this for informational purposes only and don't guarantee its accuracy. The success indicator is only really meaningful when we generate the state-leave notification; it indicates the overall success of the update.

largefiles: add abstract methods in remotestore class Methods _put, _get, _stat were used in remotestore class as abstract expecting that subclass would implement them. This commit makes this fact explicit.

test-parse-date: defines explicit start/end dates for DST Prior to this patch, DST times where tested by specifying a custom TZ environment variable that didn't defined DST transition times. Due to a bug in glibc, the test fail on 32bits platforms that use timezone files generated by zic from tzcode >= 2014c (glibc >= 2.20). See https://sourceware.org/bugzilla/show_bug.cgi?id=19738 By defining explicit transition times for DST in the TZ environment variable, the test is now independant to how the system guess those transition times.
