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. Benchmark: There is a little overhead at module import: python -m timeit "import hgext.fsmonitor" Windows before patch: 1000000 loops, best of 3: 0.563 usec per loop Windows after patch: 1000000 loops, best of 3: 0.583 usec per loop Linx before patch: 1000000 loops, best of 3: 0.579 usec per loop Linux after patch: 1000000 loops, best of 3: 0.588 usec per loop 10000 calls to _watchmantofsencoding: python -m timeit -s "from hgext.fsmonitor import _watchmantofsencoding, _fixencoding" "fname = '/path/to/file'" "for i in range(10000):" " if _fixencoding: fname = _watchmantofsencoding(fname)" Windows (_fixencoding is True): 100 loops, best of 3: 19.5 msec per loop Linux (_fixencoding is False): 100 loops, best of 3: 3.08 msec per loop

pull: abort pull --update if config requires destination (issue5528)

tests: move update requiredest test to own test file More tests for this flag are coming in upcoming patches.

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.

bundlerepo: use raw revision in revdiff() This is similar to "revlog: use raw revisions in revdiff". revdiff() generates raw text used in revlog directly. This makes test-flagprocessor.t happy.

bundlerepo: fix raw handling in revision() Similar to fixes in revlog.py, this patch uses "rawtext" to explicitly label contents expected to be raw, and makes sure content stored in _cache is raw text. Now test-flagprocessor.t points us to another issue.

bundlerepo: build revlog index with flags This fixes bundlerevlog.flags(rev) for any revisions provided by the bundle. Now test-flagprocessor.t points us to another issue.

bundlerepo: make baserevision return raw text "baserevision" returns the text that will be used to apply deltas. Since deltas are against raw texts, "baserevision" should return raw text. Now test-flagprocessor.t points us to a new error.

test-flagprocessor: add tests about bundlerepo This shows flag processor is broken with a bundle repo. The test creates non-liner history to exercise code path where the deltaparent cannot be reused.

test-flagprocessor: use changegroup3 in bundle2 This will force "hg bundle" to use changegroup3 in the test. It is important since only changegroup3 preserves revlog flags.

bundle: allow bundle command to use changegroup3 in tests Since bundle2 writes changegroup version, we can just reuse the bundle2 format for changegroup3. This won't enable the bundle command to write changegroup3 in the wild, since exchange.parsebundlespec only returns changegroup2. It unlocks tests to override exchange.parsebundlespec and get "hg bundle" write changegroup3.

tests: add per-line output conditionals for Windows

run-tests: support per-line conditional output in tests Duplicating entire tests just because the output is different is both error prone and can make the tests harder to read. This harnesses the existing '(?)' infrastructure, both to improve readability, and because it seemed like the path of least resistance. The form is: $ test_cmd output (hghave-feature !) # required if hghave.has_feature(), else optional out2 (no-hghave-feature2 !) # req if not hghave.has_feature2(), else optional I originally extended the '(?)' syntax. For example, this: 2 r4/.hg/cache/checkisexec (execbit ?) pretty naturally reads as "checkisexec, if execbit". In some ways though, this inverts the meaning of '?'. For '(?)', the line is purely optional. In the example, it is mandatory iff execbit. Otherwise, it is carried forward as optional, to preserve the test output. I tried it the other way, (listing 'no-exec' in the example), but that is too confusing to read. Kostia suggested using '!', and that seems fine.

test-run-tests: pad the failure test to preserve the run order Test size seems to dictate the order in which the tests are run, and the next patch will add to test-success.t. Similar to c0cecc153d25.

run-tests: prevent a (glob) declaration from reordering (?) lines Previously, if a series of optional output lines marked with '(?)' had a (glob) in one of the first lines, the output would be reordered such that it came last if none of the lines were output. The (re) declaration wasn't affected, which was helpful in figuring this out. There were no tests for '(re) (?)' so add that to make sure everything plays nice.

py3: use pycompat.byteskwargs() to convert opts to bytes We have converted opts to unicodes before passing them.

test-check-code: do not use xargs We have too many files, and passing them via arguments could cause strange errors on some platforms [1]. Since check-code.py can now take "-" and read file names from stdin, use it instead of xargs to avoid the argv size limit. [1]: https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096346.html

check-code: use "-" to specify a list of files from stdin This will be used by the next patch.

perf: add historical portability for util.timer util.timer has been introduced in ae5d60bb and used in perf.py since 22fbca1d. For historical portability, forcibly define util.timer in perf.py

diff: add --binary option for git mode diffs This patch adds --binary option to `hg diff` and `hg export` to allow more control about when binary diffs are displayed in Git mode as well as some tests to verify it behaves correctly (issue5510).

patch: make diff in git mode respect --text option (issue5510) This changeset makes patch respect -a/--text option in --git mode by aligning its behaviour with git itself.

py3: have registrar process docstrings in bytes Mixing bytes and unicode creates a mess. Do things in bytes as possible. New sysbytes() helper only takes care of ASCII characters, but avoids raising nasty unicode exception. This is the same design principle as sysstr().

localrepo: fix deprecation version for 'repo._link' The patch lingered for a while and nobody noticed when it was resubmitted.

localrepo: fix deprecation version for 'repo.join' The patch lingered for a while and nobody noticed when it was resubmitted.

tests: make zstd-related output optional Caught by the buildbot with --pure, fix suggested by indygreg.

check-code: update test IP address enforcement checks Instead of mentioning 127.0.0.1, we should use $LOCALIP. Anytime $LOCALIP appears in output, we should make sure we use (glob) on that line of output so that weird environments that do remapping jiggery pokery (such as our FreeBSD buildbot that's in a jail) don't get spurious test failures.

tests: fix missing (glob) annotations in test-push-http.t

tests: fix missing (glob) annotations in test-push-http-bundle1.t

tests: fix missing (glob) annotations in test-https.t

tests: fix missing (glob) annotations in test-bundle2-exchange.t

util: fix %-formatting on docstring by moving a closing parenthesis We have to do the % formatting over the sysstr, since the things we're going to splat into it are themselves sysstrs. This is probably technically wrong-ish, since bt is probably actually a bytestr here, but this fixes the immediate issue, which was that hg was broken on Python 3.

revset: stop supporting plain list as input set (API) There was no deprecwarn(), but this is the same kind of API compatibility as the one removed by the previous patch.

revset: stop supporting predicate that returns plain list (API) It's said to be removed after 3.9.

mdiff: add a hunkinrange helper function This factors out hunk filtering logic by line range that is similar in mdiff.blocksinrange() and hgweb.webutil.diffs().

templater: provide loop counter as "index" keyword This was originally written for JSON templating where we would have to be careful to not add extra comma, but seems generally useful. Inner loop started by % operator has its own counter.

templater: rename variable "i" to "v" in runmap() I want to reuse "i" for index.

formatter: reorder code that builds template mapping This makes the future patch slightly simpler.
