parsers: ensure correct return type for inline_scan The returned data type for inline_scan should be Py_ssize_t rather than long. Based on warning from Microsoft Visual C++ 2008.

parsers: fix typing issue when constructing Python integer object The passed variable is a Py_ssize_t, not a long, and consequently should use PyInt_FromSsize_t rather than PyInt-FromLong. Fixed based on warning from Microsoft Visual C++ 2008.

parsers: use bitmask type consistently in find_gca_candidates Normalized type usage in find_gca_candidates triggered by warning from Microsoft Visual C++ 2008.

revert: drop `lexist` check in the backup logic We are no longer trying to backup files that do not exist on disk. This check can be safely dropped.

revert: distinguish between deleted file and locally modified Locally modified needs a backup while a deleted file cannot be backed up because there is no file to backup.

revert: detect unknown files in the same path as files marked as removed Such unknown files may need to be backed up. Having them identified beforehand will help simplify the backup logic. We now use different sets with different backup strategies.

revert: cache working context in a variable During the silicon age, humans on planet Earth discovered the use of variables. This marvelous invention let them improve both code readability and performance.

obsolete: properly drop 'date' from metadata Mistakes were made while resolving rebase conflicts in 4bc96685a40c. This led to 'date' being preserved in metadata when reading markers from a binary stream. As a result, some known markers were seen as "new" when pulling. I noticed it because a no-op pulls from main added about 600 duplicated markers to my obsstore (for each pull). I do not believe we need to perform any specific action to actively de-duplicates existing obsstore. After this fix, duplicated markers will no be propagated and the few affected repositories can probably deal with duplication (or people can repull the obsstore from a clone). As a side effect, we decode metadata only once, reducing the impact of the hack in fm0 to store extra important data (parents and date).

templater: implement __len__ for _hybrid Objects of class _hybrid are returned by such template keywords as children, bookmarks, tags and others, and also by revset() template function. They are representing "list of strings" (as hg help template says) for use in templates. So it would be logical to implement a handy way to count the number of strings in such list, and that's what __len__ method does.

tests: remove unnecessary apostrophe

run-tests: added '--json' functionality to store test result in json file This patch added a new functionality '--json'. While testing, if '--json' is enabled then test result data gets stored in newly created "report.json" file in the following format. testreport ={ "test-success.t": { "result": "success", "time": "2.041" } "test-failure.t": { "result": "failure", "time": "4.430" } "test-skip.t": { "result": "skip" "time": "3.754" } } Otherwise, if '--json' is enabled but json module was not installed then it will raise an error "json module not installed". This "report.json" file will further accessed by html/javascript file for graph usage.

changegroup: rename bundle-related functions and classes Functions like getbundle and classes like unbundle10 really manipulate changegroups and not bundles. A HG10 bundle is the same as a changegroup plus a small header, but this is no longer the case for a HG2X bundle, so it's better to separate the names a bit.

comments: describe ancestor consistently - avoid 'least common ancestor' "best" is as defined by mercurial.ancestor.ancestors: furthest from a root (as measured by longest path).

rebase: improve description of --base No Mercurial DAG has ever (!) been drawn in a way where 'up to' would apply. Instead, describe deliberatey vague and informal instead of seemingly precise but not describing the essentials: rebase the tree around the specified changeset without ancestors of dest

dagutils: fix docstrings for singleton internalize/externalize

cmdutil: avoid the confusing name 'patch' for a matcher

fedora: remove sample.hgrc from shipped files sample.hgrc was long obsolete and was removed in 63ed188e3fc7.

config: propose some sample global config file An example of what could be suggested to the user as a global config file. Trying to be conservative here, and only suggesting the safest possible extensions. In addition to the user-level extensions, the blackbox extension is something a sysadmin might reasonable want to enable for every repo on the system.

config: give more fine-tuned sample hgrcs to this command The hgrc for user config is typically different from the hgrc at the system-wide or repository level. This patch provides different sample hgrcs for each level. Sometimes when copying repos around, the copy or the original don't have a default path yet, so at least for `hg config -l`, this ought to provide a more reasonable default and suggestions of what typically goes there. The actual sample configs go in the config.py file, to minimise clutter. In order to avoid an unnecessary import, the corresponding import for this dictionary is at the file level.

rebase: add a deprecated -i/--interactive flag A common mistake can be to type 'hg rebase -i' to discover interactive history editing. We add a -i/--interactive flag as discussed in the sprint and deprecate it right away, but hint people using it to use histedit instead.

revlog: introduce isancestor method for efficiently determining node lineage Hide the not so obvious use of commonancestorsheads.

clone: provide sample username = config entry in .hg/hgrc (issue4359) Some users clone from a server before ever running 'hg config --edit', so they don't see our helpful template for things like enabling the username. Attempt to give them some helpful guidance.

test-acl: alter sed construct to avoid changes in .hg/hgrc formatting A future patch is going to add some extra commented-out boilerplate to the top of .hg/hgrc during clone. In order to make this test not require regular updates, switch to searching for [hooks] or [acl] and print file from the first match to that pattern.

dispatch: check shell alias again after loading extensions (issue4355) Before this patch, the shell alias causes failure when it takes its specific (= unknown for "hg") options in the command line, because "_parse()" can't accept them. This is the regression introduced by 03d345da0579. It fixed the issue that ambiguity between shell aliases and commands defined by extensions was ignored. But it also caused that ambiguous shell alias is handled in "_parse()" even if it takes specific options in the command line. To avoid such failure, this patch checks shell alias again after loading extensions. All aliases and commands (including ones defined by extensions) are completely defined before the 2nd (= newly added in this patch) "_checkshellalias()" invocation, and "cmdutil.findcmd(strict=False)" can detect ambiguity between them correctly. For efficiency, this patch does: - omit the 2nd "_checkshellalias()" invocation if "[ui] strict= True" it causes "cmdutil.findcmd(strict=True)", of which result should be equal to one of the 1st invocation before adding aliases - avoid removing the 1st "_checkshellalias()" invocation it causes "cmdutil.findcmd(strict=True)" invocation preventing shell alias execution from loading extensions uselessly

dispatch: make "_checkshellalias" reusable regardless of adding aliases To reduce changes in the subsequent patch fixing issue4355, this patch makes "_checkshellalias" reusable regardless of adding aliases. In this patch, alias definitions are added and restored, only when "precheck=True".

build: don't clean __version__.py on 'make clean' in release tarballs When running 'make clean' in an extracted release tarball, file mercurial/__version__.py is removed, causing a subsequent install to indicate 'version unknown'. This problem was reported in the past [1] and a patch proposed in that mail, but was never properly sent nor applied. [1] http://selenic.com/pipermail/mercurial/2010-December/036249.html

revert: drop now useless conditional in the backup check Now that we removed the (hopeless) attempt to backup file we knew to be missing in the target changeset, we can stop checking if the file exists in the target changeset.

revert: no backup for `dsadded` set There is only one case where a backup is required in the `dsadded` set, and the current backup mechanism fails to handle it. So we stop trying to do backups at all for now. This will help us to simplify the backup code and finally fix this backup issue.

revert: add more padding in the dispatch list We are going to add more sets and some of them will have longer names. We add padding in a standalone patch for readbility purposes.
