pull: add help information about pulling active bookmark

templates: add support for search webcommand in json style

templates: add support for summary webcommand in json style Change summary webcommand to yield each element of the shortlog instead of the entire list. This makes generated json more readable since each entry can be formatted separately, instead of returning all the shortlog content in a single string.

templates: add support for filerevision webcommand in json style

templates: add support for filelog webcommand in json style Modify changelistentry structure to also deliver phase and branch data and use either 'parents' or 'allparents' depending on what is defined in the view, in order to reuse it in filelog structure.

largefiles: make cloning not ask two times about password (issue4883) Before this commit url.opener overwritten stored password for connection with given url/user even when new password for given connection was not filled. This commit makes opener overwrites saved authentication only when it contains password.

url: remember http password database in ui object This makes http password database stored in ui object. It allows reusing authentication information when we use this database for creating password manager for the new connection.

url: extract password database from password manager So far password manager was keeping authentication information so opening new connection and creating new password manager made all saved authentication information lost. This commit separates password manager and password database to make it possible to reuse saved authentication information. This commit violates code checker because it adds add_password method (name with underscore) to passwordmgr object to provide method required by urllib2.

bookmarks: add 'hg pull -B .' for pulling the active bookmark (issue5258)

demandimport: delay loading for "from a import b" with absolute_import Before this patch, "from a import b" doesn't delay loading module "b", if absolute_import is enabled, even though "from . import b" does. For example: - it is assumed that extension X has "from P import M" for module M under package P with absolute_import feature - if importing module M is already delayed before loading extension X, loading module M in extension X is delayed until actually referring util, cmdutil, scmutil or so of Mercurial itself should be imported by "from . import M" style before loading extension X - otherwise, module M is loaded immediately at loading extension X, even if extension X itself isn't used at that "hg" command invocation Some minor modules (e.g. filemerge or so) of Mercurial itself aren't imported by "from . import M" style before loading extension X. And of course, external libraries aren't, too. This might cause startup performance problem of hg command, because many bundled extensions already enable absolute_import feature. To delay loading module for "from a import b" with absolute_import feature, this patch does below in "from a (or .a) import b" with absolute_import case: 1. import root module of "name" by system built-in __import__ (referred as _origimport) 2. recurse down the module chain for hierarchical "name" This logic can be shared with non absolute_import case. Therefore, this patch also centralizes it into chainmodules(). 3. and fall through to process elements in "fromlist" for the leaf module of "name" Processing elements in "fromlist" is executed in the code path after "if _pypy: .... else: ..." clause. Therefore, this patch replaces "if _pypy:" with "elif _pypy:" to share it. At 4f1144c3c72b introducing original "work around" for "from a import b" case, elements in "fromlist" were imported with "level=level". But "level" might be grater than 1 (e.g. level=2 in "from .. import b" case) at demandimport() invocation, and importing direct sub-module in "fromlist" with level grater than 1 causes unexpected result. IMHO, this seems main reason of "errors for unknown reason" described in 4f1144c3c72b, and we don't have to worry about it, because this issue was already fixed by 78d05778907b. This is reason why this patch removes "errors for unknown reasons" comment.

import-checker: increase portability for python 2.6.x Before this patch, fromlocalfunc() assumes that "module" attribute of ast.ImportFrom is None for "from . import a", and Python 2.7.x satisfies this assumption. On the other hand, with Python 2.6.x, "module" attribute of ast.ImportFrom is an empty string for "from . import a", and this causes failure of test-check-module-imports.t.

scmutil: allow access to filecache descriptor on class To make it easier to patch the wrapped function, make it possible to access the filecache descriptor directly on the class (rather than have to use ClassObject.__dict__['attributename']). Returning `self` when the first argument to `__get__` is `None` makes the descriptor behave the same way `property` objects do.

rebase: do not abort if all changesets have equivalents in the destination

changegroup: don't send empty subdirectory manifest groups When grafting/rebasing, it is common for multiple changesets to make the same change to a subdirectory. When writing the revlog for the directory, the revlog code already takes care of not writing the entry again. In 0c2a088ffcc5 (changegroup: prune subdirectory dirlogs too, 2016-02-12), I added the corresponding code in changegroup (not sending entries the client already has), but I forgot to avoid sending the entire changegroup if no nodes remained in the pruned set. Although that's harmless besides the wasted network traffic, the receiving side was checking for it (copied from the changegroup code for handling files). This resulted in the client crashing with: abort: received dir revlog group is empty Fix by simply not emitting a changegroup for the directory if there were no changes is it. This matches how files are handled.

chg: ignore SIGINT while waiting pager termination Otherwise the terminal would be left with unclean state. This is what fcc4b55876c3 does.

chg: reset signal handlers to default before waiting pager Our signal handlers forward signals to the server process, but it will disappear soon after hgc_close(). So we should unregister handlers before hgc_close(). Otherwise chg would abort due to kill(perrpid, sig) failure. The problem is spotted by SIGWINCH while waiting pager termination.

help: document that [subpaths] may rewrite relative paths The subpaths substitution logic first attempts to match the absolute repository path, then the relative subrepository path if that failed.

doc: describe detail about checkambig optional argument This is followup for patches below, which add checkambig argument to existing function. - 731ced087a4b - 76f1ea360c7e - ce2d81aafbae - a109bf7e0dc2

ui: provide official way to reset internal state per command This will allow us to clear in-memory password storage per runcommand(). I've updated commandserver to call resetstate() of both ui and repo.ui because they may have different states in theory.

revset: extract function that validates sort() arguments This function will be used in _optimize() to get rid of noop sort() call while validating its arguments.

revset: build dict of extra sort options before evaluating set Prepares for extracting a function that only validates sort options.

revset: build list of (key, reverse) pairs before sorting Prepares for extracting a function that only validates sort options.

revset: fix crash on empty sort key Make it noop as before 2188f170f5b6. We could change it to an error, but allowing empty key makes some sense for scripting that builds a key string programmatically.

rebase: move local variable 'targetancestors' to the RR class

rebase: move local variable 'skipped' to the RR class

rebase: move local variable 'target' to the RR class

rebase: introduce a rebaseruntime (RR) class rebaseruntime is a class that will in future contain all of the state necessary to perform rebase operation and have pieces of rebase logic as its methods. This commit introduces the class and moves the following local variables to be its fields: - originalwd - external - state - activebookmark

chg: change default connect timeout to 60 seconds As discussed at https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-June/085290.html The default 10-second timeout is not enough if the machine is overloaded. Let's increase it to 60 seconds.

tests: increase test-https malform error glob The recently introduced (ecc9b788fd690a0a) test around malformed pem files hard codes an error message which doesn't appear to be cross platform agnostic. On our machines (centos6 if it matters) the test output differs: - abort: error: unknown error* (glob) + abort: error: _ssl.c:330: error:00000000:lib(0):func(0):reason(0) This patch increases the glob to cover the entire error message.

largefiles: make storefactory._openstore public In storefactory opening store is the main functionality, so it shouldn't be marked as private with underscore.

bookmarks: abort 'push -B .' when no active bookmark

transaction: avoid ambiguity of file stat at restoring from backup In some cases below, copying from backup is used to restore original contents of a file, which is backuped via addfilegenerator(). If copying keeps ctime, mtime and size of a file, restoring is overlooked, and old contents cached before restoring isn't invalidated as expected. - failure of transaction (from '.hg/journal.backup.*') - rollback of previous transaction (from '.hg/undo.backup.*') To avoid ambiguity of file stat at restoring, this patch invokes util.copyfile() with checkambig=True.
