crecord: avoid setting non-existing SIGTSTP signal on windows (issue5512) Windows do not have a SIGTSTP so we avoid setting the handler if the signal is unknown.

crecord: ensure we reinstall the SIGTSTP handler Previous, exceptions would prevent the reinstallation of the signal.

crecord: avoid setting non-existing signal SIGWINCH on windows Windows do not have a SIGWINCH so we avoid setting the handler if the signal is unknown.

crecord: ensure we reinstall the SIGWINCH handler Previous, exception in _main(...) would prevent the reinstallation of the signal.

crecord: extract most of 'main' into a sub function There are some setup and cleanup necessary around the main code, that setup/cleanup code needs multiple adjustments so we extract the core code into its own function first for clarity.

templater: add shorthand for building a dict like {"key": key} Like field init shorthand of Rust. This is convenient for building a JSON object from selected keywords. This means dict() won't support Python-like dict(iterable) syntax because it's ambiguous. Perhaps it could be implemented as 'mapdict(xs % (k, v))'.

templater: find keyword name more thoroughly on filtering error Before, it could spill an internal representation of compiled template such as [(<function runsymbol at 0x....>, 'extras'), ...]. Show less cryptic message if no symbol found. New findsymbolicname() function will be also used by dict() constructor.

templater: add dict() constructor It's troublesome to build JSON by template, so let's add programmatic way.

templatekw: add public function to wrap a dict by _hybrid object

templatekw: add public function to wrap a list by _hybrid object

templatekw: add default implementation of _hybrid.gen This is convenient for new template keyword, which doesn't need to support the legacy list hack (provided by _showlist()), but still wants to have a string representation.

parser: preserve order of keyword arguments This helps building dict(key1=value1, ...) in deterministic way.

parser: extend buildargsdict() to support arbitrary number of **kwargs Prepares for adding dict(key1=value1, ...) template function. More tests will be added later.

parser: verify excessive number of args excluding kwargs in buildargsdict() This makes the next patch slightly simpler. We don't need to check the excessive number of keyword arguments since unknown and duplicated kwargs are rejected.

obsolescence: add test case B-7 for obsolescence markers exchange About 3 years ago, in August 2014, the logic to select what markers to select on push was ported from the evolve extension to Mercurial core. However, for some unclear reasons, the tests for that logic were not ported alongside. I realised it a couple of weeks ago while working on another push related issue. I've made a clean up pass on the tests and they are now ready to integrate the core test suite. This series of changesets do not change any logic. I just adds test for logic that has been around for about 10 versions of Mercurial. They are a patch for each test case. It makes it easier to review and postpone one with documentation issues without rejecting the wholes series.

upgrade: simplify the "origin" dispatch in dry run We could compute the final set we need directly.

upgrade: use 'improvement' object for action too This simplify multiple pieces of code. For now we restrict this upgrade to the top level function to keep this patch simple.

upgrade: implement equality for 'improvement' object Through the code, we use a mix of 'improvement' object and string. Having a single type would be simpler. For this we need the object to be comparable.

upgrade: simplify some of the initial dispatch for dry run Since we already have the list of deficiencies, we can use it directly.

upgrade: simplify 'determineactions' Since we only takes 'deficiencies', we can simplify the function and clarify its arguments.

upgrade: filter optimizations outside of 'determineactions' This sounds like higher level logic to process arguments. Moving it out of 'determineactions' will allow passing only deficiencies to the function. Then, in a future changeset, we will remove dispatch on "improvement type" within the function. See next changeset for details.

upgrade: directly iterate over optimisations Since we already have the list of optimisations independent from the deficiencies, we can use it directly. (we make a dual assignement in this changeset to simplify the next one)

upgrade: simplify optimisations validation Since we fetch optimizations distinctly from the deficiencies, we can simplify some code.

upgrade: split finding deficiencies from finding optimisations Our ultimate goal is to make it easier to get a diagnostic of the repository format. A first important and step for that is to separate part related to repository format from the optimisation. We start by having two different functions returning the two categories of possible "improvement".

upgrade: update the copyright statement

upgrade: update the header comment

upgrade: import 'localrepo' globally The in-function imports mention a cycle that seems to no longer be relevant. As a result, we just import it globally.

largefiles: set the extension as enabled locally after a share requiring it This has been done for clone since e1dbe0b215ae, so it makes sense here for the same reasons.

windows: add context manager support to mixedfilemodewrapper I stumbled into this in the next patch. The difference between getting a context manager capable object or not from vfs classes was as subtle as adding a '+' to the file mode.

chg: always wait for pager Previously, when runcommand raises, chg aborts with, and does not wait for pager. The call stack is like: hgc_runcommand -> handleresponse -> readchannel -> debugmsg("failed to read channel") -> exit(255) That means, chg returns to the shell, then both the pager and the shell will read from the terminal at the same time, causing problems. This patch fixes that by using "atexit" to register the pager cleanup function so chg will always wait for pager even if runcommand raises.

bundle2: move 'seek' and 'tell' methods off the unpackermixin class These methods are unrelated to unpacking. They are used internally by the 'unbundlepart' class only. So me move them there as private methods. In the same go, we clarify their internal role in the their docstring.

shelve: rename nodestoprune to nodestoremove As per feedback from the community.

templater: port pad() to take keyword arguments This is another example where keyword arguments can be actually useful.

templater: add support for keyword arguments Unlike revset, function arguments are pre-processed in templater. That's why we need to define argspec per function. An argspec field looks somewhat redundant in @templatefunc definition as a name field contains human-readable list of arguments. I'll make function doc be built from argspec later. Ported separate() function as an example.

templater: add parsing rule for key-value pair Based on the revset implementation, 70a2082f855a. This patch also adjusts the test as '=' is now a valid token.

templater: adjust binding strengths to make room for key-value operator Changed as follows: - template ops (%, |): +10 - arithmetic ops: +1 (but "negate" should be greater than "%")

templater: sort token table by binding strength Just for readability.

templater: make _hybrid provide more list/dict-like methods So the JSON filter works.

templater: hide private variable of _hybrid

templater: remove __iter__() from _hybrid, resolve it explicitly The goal is to fix "{hybrid_obj|json}" output. A _hybrid object must act as a list or a dict as well as a generator of legacy template strings. Before, _hybrid.__iter__() was assigned for legacy template, which conflicted with list.__iter__() API. This patch drops _hybrid.__iter__() and makes stringify/flatten functions unwrap a generator instead.

templater: rewrite doc of _hybrid class as docstring

sortdict: fix .pop() to return a value My future patch will need it.

checkcode: only match pushd/popd as word otherwise it partially match common words like "pushdestination".

treemanifest: add walksubtrees api Adds a new function to treemanifest that allows walking over the directories in the tree. Currently it only accepts a matcher to prune the walk, but in the future it will also accept a list of trees and will only walk over subtrees that differ from the versions in the list. This will be useful for identifying what parts of the tree are new to this revision, which is useful when deciding the minimal set of trees to send to a client given that they have a certain tree already. Since this is intended for an extension to use, the only current consumer is a test. In the future this function may be useful for implementing other algorithms like diff and changegroup generation.

upgrade: extract code in its own module Given about 2/3 or 'mercurial.repair' is now about repository upgrade, I think it is fair to move it into its own module. An expected benefit is the ability to drop the 'upgrade' prefix of many functions. This will be done in coming changesets.

bundle2: move the 'close' method off the unpackermixin This method is unrelated to unpacking and only used by the unbundle20 class. We move it there for clarity.

bundle2: clarify the docstring of unpackermixin methods The unpackermixin is a utility used to implement the bundle2 protocol. It should not be used when writing part handlers. We update the docstring to clarify this.

bundle2: add documention to 'part.addparams' There are some non-obvious limitations on the parameters of this method. Add some documentation where people will likely look to understand how to use this API.

test-patchbomb: disable sendmail tests on Windows These tests were failing, and there isn't a trivial way to execute a script on Windows [1]. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096497.html

show: fix corrupt json output with no bookmarks

show: tweak plain abort language for clarity

tests: print Unix style paths in *.py tests These tests don't support (glob). I didn't audit all tests, but these ones were failing.

revlog: make "size" diverge from "rawsize" Previously, revlog.size equals to revlog.rawsize. However, the flag processor framework could make a difference - "size" could mean the length of len(revision(raw=False)), while "rawsize" means len(revision(raw=True)). This patch makes it so. This corrects "hg status" output when flag processor is involved. The call stack looks like: basectx.status -> workingctx._buildstatus -> workingctx._dirstatestatus -> workingctx._checklookup -> filectx.cmp -> filelog.cmp -> filelog.size -> revlog.size

test-flagprocessor: add a case about hg status This shows how "hg status" is wrong - nothing changed but the file is labeled as "M".

test-http-proxy: add the Windows variant of "connection refused" The full error is "No connection could be made because the target machine actively refused it".

test-fileset: eliminate a duplicate test that was conditionalized for output

test-fileset: glob away hash differences There are various files committed above that can't be used on Windows because of the name, or being a symlink.

test-bundle: glob away a URL protocol separator MSYS thinks the ':' is a Unix path separator, and replaces it with ';'.

templatekw: clarify the result of {latesttag} when no tag exists My initial expectation was that the list would be empty, and therefore detectable with {if()}. The map for {latesttag()} is populated with real values in this case (except {tag}), so it probably doesn't make any sense to change this to an empty list.

hgweb: position the "followlines" box close to latest cursor position

hgweb: add a floating tooltip to invite on followlines action In followlines.js, we create a <div id="followlines-tooltip"> element to draw attention of users on "followlines" feature. The element shows up on hover of source lines after one second and follows the cursor. After first click (start line selection), the text changes and indicates that next click will terminate selection.

zstd: vendor python-zstandard 0.8.1 This contains a fix for compilation on BSDs. #no-check-commit

fsmonitor: match watchman and filesystem encoding watchman's paths encoding can differ from filesystem encoding. For example, on Windows, it's always utf-8. Before this patch, on Windows, mismatch in path comparison between fsmonitor state and osutil.statfiles would yield a clean status for added/modified files. In addition to status reporting wrong results, this leads to files being discarded from changesets while doing history editing operations such as rebase.

py3: add pycompat.unicode and add it to importer On python 3, builtins.unicode does not exist.

py3: add a bytes version of urllib.parse.urlencode() to pycompat.py urllib.parse.urlencode() returns unicodes on Python 3. This commit adds a method which will take its output and encode it to bytes so that we can use bytes consistently.

py3: replace str() with bytes()

metadataonlyctx: replace "changeset()[0]" to "manifestnode()" As Yuya pointed out [1], "changeset()[0]" could be simplified to "manifestnode()". I didn't notice that method earlier. It should definitely be used - it's easier to read, and faster. [1]: https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-March/095716.html

test-check-pylint: match its output "pylint --version" shows: pylint 2.0.0, astroid 1.5.0 Python 2.7.13 (default, Dec 21 2016, 07:16:46) [GCC 6.2.1 20160830] I got "Your code has been rated at 10.00/10" every time and didn't know how to turn it off. Therefore the fix.

test-flagprocessor: remove unnecessary greps The "2>&1 | egrep ..." code is used for removing uninteresting parts from tracebacks. Now the test does not dump tracebacks, they can be removed.
