tests: add a missing abort exit code on Windows in test-audit-subrepo.t

subrepo: add test for Windows relative-ish path with drive letter Matt Harbison pointed out that Windows had some weird path syntax. Fortunately it's rejected appropriately by pathauditor, so we're safe. Let's test the behavior as we have a special handling for Windows drive letters. This patch includes a basic example. Maybe we'll need to extend the test case further, but writing such tests on Linux isn't easy.

copies: return True instead of filename as it is expected to return boolean As the function documentation says this function should True if we hit a match and False otherwise.

templatekw: add a {negrev} keyword Revision numbers are getting much maligned for two reasons: they are too long in large repos and users get confused by their local-only nature. It just occurred to me that negative revision numbers avoid both of those problems. Since negative revision numbers change whenever the repo changes, it's much more obvious that they are a local-only convenience. Additionally, for the recent commits that we usually care about the most, negative revision numbers are always near zero. This commit adds a negrev templatekw to more easily expose negative revision numbers. It's not easy to reliably produce this output with existing keywords due to hidden commits while at the same time ensuring good performance.

tests: correct the remaining fallout from recent path style changes on Windows Per @martinvonz, `ui.slash` set by the test runner is now capable of playing a more active role.[1] I verified that both of these work by setting `ui.slash` to False, but these changes seem cleaner. The problem with check-perf-code.py was that the proper imports were not being whitelisted due to '\' vs '/'. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2019-February/128701.html

templates: adding a config() function for template customization This allows templates to be written such that users can customize them easily, or that they can be customized based on other configuration of the system. For enterprise deployments, we often have complex template aliases, and right now the only way individual users can customize those is by replacing the whole template alias (which means they won't get company-wide updates to it anymore, plus most users don't want to have to get a complex template right). With this change, they can just set a config option which feeds into our templates for common changes (e.g. whether to limit commit descriptions to the width of their terminal or not). To work around the issue of having to register the config options, I declared a dedicated section [templateconfig] for these options to be dynamically declared. They can still reference any other config option that's registered elsewhere. I only did string, bool and int at this time - list and date would add other complications with parsing the default so I'll leave that as an exercise to the reader :) Differential Revision: https://phab.mercurial-scm.org/D5959

changegroup: don't try to prune manifest nodes if not ellipses In non-ellipses case, the number of manifest nodes can be very big, and finding whether one of them can be pruned or not is very costly. For each node, we try to find the rev and the linkrev, which is expensive. Sending bit more manifest nodes seems better and much faster here. On our internal repository, this saves around 5 seconds on `hg tracked --addinclude <some_path>` on a narrow repo with ellipses disabled. Differential Revision: https://phab.mercurial-scm.org/D5782

branchmap: improve doc about BranchMapCache class It was confusing that we are having two different branchcache and BranchMapCache classes.

rust: itering less on MissingAncestors.bases for max() Instead of iterating on the whole `self.bases` each time to find its max, we keep the latter in a separate member attribute and keep it up to date in `add_bases()` On a perfdiscovery done on PyPy, with repos prepared with `contrib/discovery-helper.sh 50 100`, this gives a slight improvement (around 0.5% on wall time, but 10% on CPU) before: ! wall 0.172801 comb 0.180000 user 0.180000 sys 0.000000 (median of 541) after: ! wall 0.171798 comb 0.160000 user 0.160000 sys 0.000000 (median of 551) (perf command run time upped because of bigger variability during this test).

rust: stop putting NULL_REVISION in MissingAncestors.bases As noted in initial review of MissingAncestors, adding NULL_REVISION in constructor in case the given `bases` is empty wasn't really useful, yet it's been kept for identity with the Python implementation Differential Revision: https://phab.mercurial-scm.org/D5944

rust: less set lookups in MissingAncestors using the return values of HashSet::remove(), we can factor pairs of `contains()/remove()` into a single `remove()`. On a perfdiscovery run done on the PyPy repository, prepared with contrib/discovery-helper.sh 50 100, I do get a modest improvement with this (mean of medians of three runs is better by 2%) Sample readings, before this change: ! wall 0.175609 comb 0.180000 user 0.180000 sys 0.000000 (median of 58) With this change: ! wall 0.171662 comb 0.180000 user 0.170000 sys 0.010000 (median of 60) Differential Revision: https://phab.mercurial-scm.org/D5943

url: don't pass strict argument on Python 3 The argument was removed in Python 3.4. Differential Revision: https://phab.mercurial-scm.org/D5975

url: always use str for proxy configuration Previously, proxies didn't work on Python 3 for various reasons. First, the keys to the "proxies" dict are fed into a `setattr(self, "%s_open", ...)` call and passing bytestrings results in setting an oddly named attribute due to the b'' in %s formatting. This resulted in "http_open" and "https_open" not being properly overridden and proxies not being used. Second, the standard library was expecting proxy URLs to be str. And various operations (including our custom code in url.py) would fail to account for the str/bytes mismatch. This commit normalizes everything to str and adjusts our proxy code in url.py to account for the presence of str on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5952

py3: port tinyproxy.py to work with Python 3 There were various str/bytes mismatches in the code. This caused the proxy server to misbehave at run-time. The manifestation was typically premature socket disconnect from the perspective of the client. Differential Revision: https://phab.mercurial-scm.org/D5951

url: always access req._tunnel_host The getattr() was there to handle Python versions before 2.6, which lacked this attribute. We /might/ be able to further delete some code here.

exchange: raise error.Abort instead of ValueError Raising ValueError results in an uncaught exception and a traceback being printed. In the context of servers, it can result in an HTTP 500 and an exception being logged in the error log. I don't think this is proper behavior.

rust-cpython: binding for headrevs() This uses the core `dagops::retain_heads` to give a Rust implementation to `mercurial.dagop.headrevs`. Testing happens for now from `test-rust-ancestors.py` (for quick and minimal change), but it'd made more sense to put the binary index data elsewhere and to create a new test python module

rust-cpython: moved py_set() utility to conversion module We're still hoping to get rid of it eventually, but we're going to need it from outside the `ancestors` module before that.

rust: translated random test of missingancestors This is a Rust implementation of the random DAG generator and related incrementalmissingancestors tests against a naive brute force implementation. It is provided as an integration test, so that it won't run by default if any unit test fails. In case of a failed example, all needed information for reproduction is included in the panic message, (this is how `test_remove_ancestors_from_case1()` has been generated), as well as the random seed. The whole test is rerunnable by passing the random seed in the TEST_RANDOM_SEED environment variable. The other parameters (numbers of iterations) can be passed in the TEST_MISSING_ANCESTORS environment variable. An alternative would have been to expose to Python MissingAncestors<VecGraphs> but that would have meant pollution of the release build used from Python, whereas we do it in this changeset within the tests submodule Differential Revision: https://phab.mercurial-scm.org/D5417

They're now all ready to be switched over to respecting ui.relative-paths. Differential Revision: https://phab.mercurial-scm.org/D5936

windows: use util.localpath for repo-relative paths in getuipathfn() Now that we have a single place that translates from internal path representation (slash-separated) to UI representation (i.e. scmutil.getuipathfn()), let's switch that over to using util.localpath for absolute paths. I don't expect any test impact on Windows because we still respect ui.slash, which is set by the test runner. As Yuya pointed out, a997163e7fae (status: extract helper for producing relative or absolute path for UI, 2019-01-29) accidentally changed to slash-separated paths on Windows because it used used to use repo.pathto(f, cwd='') (which calls util.localpath()) and after that patch it just prints the filename without any transformation. This patch should fix that regression. Differential Revision: https://phab.mercurial-scm.org/D5935

walkchangerevs: obey allfiles parameter when taking the slow path When walkchangerevs sees that there's a pattern, it hits the slow path. The slow path in turn reverts to the old dumb grep behaviour of only looking at files changed at each revision. Therefore, a command such as hg grep -l --all-files '.*' 'glob:**' would show you all the nonempty files touched by the current revision. This modifies that behaviour to look at the manifest at each revision instead of the changed files in case that --all-files was requested.

test: stabilize test-wireproto-exchangev2.t flaky output When running the test suite with multiple processes, we often get flaky outputs, like here: https://ci.octobus.net/job/MercurialPy2/267/console ``` - received frame(size=0; request=1; stream=2; streamflags=; type=command-response; flags=eos) add changeset cd2534766bec add changeset e96ae20f4188 add changeset caa2a465451d + received frame(size=0; request=1; stream=2; streamflags=; type=command-response; flags=eos) ``` Instead of simply sorting the clone and pull output, I saved the output in a separate file and checked the `received frame` messages on one side and then the rest of the output on the other side.

dirstate: call and cache os.getcwd() in constructor I'm about to make scmutil.matchfiles() not pass the root and cwd paths to match.exact(), since they no longer have any effect. That turned out to have the surprising effect of making some tests (test-rebase-scenario-global.t and test-removeemptydirs.t) crash when the working directory was removed. The problem was that my patch removed the call to repo.getcwd(), which caused the current working directory to not be cached in the dirstate as early as it was before.

diff: make --stat respect ui.relative-paths It would have been easy to make all diffs respect ui.relative-paths, but we don't want that since it makes the diff invalid. Perhaps it makes sense to do that with --noprefix since the point of that is to make paths that are easy to copy&paste, and the diff is already invalid anyway. But this patch just makes the --stat version respect the config option. The --stat view is not even close to a valid diff, so I think it makes sense to show the paths in more human-friendly form.

subrepo: use relative path for "already tracked" message From 932de135041f (subrepo: warn when adding already tracked files in gitsubrepo, 2015-02-27): The file is printed with abs() to be consistent with how it is printed in workingctx, even though that is inconsistent with how added files are printed in verbose mode.

Differential Revision: https://phab.mercurial-scm.org/D5899

diff: make `hg diff --root=subrepo` work The root prefix is currently stripped before adding the subrepo prefix. It seems to me that if you run `hg diff --root=subrepo` and a subrepo/ path is visited (say "subrepo/foo"), then the path generated for the diff would initially be just "foo" and we then fail (if the developer warning is active) to strip the "subrepo/" from the path. It seems like we should first add the prefix in order to produce a path that's relative to the top-level repo, and then we can remove the root prefix from that. There are no tests for this, it seems, and I don't care enough to add one. Differential Revision: https://phab.mercurial-scm.org/D5895

patch: replace "prefix" and "relroot" arguments by "pathfn" (API) The two arguments serve a very similar purpose: "relroot" is stripped from the front of the path, and then "prefix" (a subrepo path) is added (also to the front). Passing in a function that does that is more generic and will make it easier to respect ui.relative-paths in later patches (don't worry, I'm not going to respect that option for regular patches, only for --stat). I'm deliberately not calling it "uipathfn", because it's generally for producing valid diffs (including when prefix is non-empty), so things like using backslash on Windows is not an option.

subrepo: adjust subrepo prefix before calling subrepo.removefiles() (API) That's what we do with the matcher so it seems more consistent. Differential Revision: https://phab.mercurial-scm.org/D5882

py3: make sure __repr__ returns str No test fails but I found it while debugging test-commit-interactive-curses.t failure. # skip-blame because just r'' prefix Differential Revision: https://phab.mercurial-scm.org/D5878

py3: use bytes.startswith() instead of comparing with bytes[0] This is because bytes[0] will return the ascii value and comparison will fail. This makes test-commit-interactive-curses.t pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5879

match: remove unused "exact" argument (API) It seems that all callers use match.exact() instead of match.match(exact=True). Differential Revision: https://phab.mercurial-scm.org/D5919

tests: replace match.match(exact=True) by match.exact() Differential Revision: https://phab.mercurial-scm.org/D5918

patch: accept second matcher that applies only to copy sources (API) See previous patch for motivation. Differential Revision: https://phab.mercurial-scm.org/D5893

patch: let caller pass in root-filtering matcher (API) The --root option to `hg diff` does two things: * Shows paths relative to the given root * Filters paths by the given root, including copy sources The root argument is passed through down to patch.diff(). I feel like we can make patch.diff() more generic by not passing down the root argument, but instead pass: * A function for taking a repo-relative path and printing it. I want to reuse this for showing cwd-relative paths later. This is the actual motivation for this patch. * A matcher that's already been filtered by the root argument * A second matcher that filters the copy sources This is one step towards that.

patch: pass in context objects into diffhunks() (API) It's a pretty low-level function and having the contexts in patch.diff() makes future patches easier. Differential Revision: https://phab.mercurial-scm.org/D5891

convert: handle exec bit removal while converting to svn Subversion `putcommit` method checks original file's executablity to decide if executable property should be removed from svn. It is checked right after writing file contents. Content writing is implemented using `vfs.write` and vfs seems to remove exec bit, at least in some cases. This leads to executability checks being ineffective. If cset contains only this ignored exec bit removal, conversion stops with an error, because it fails to to compose svn commit properly. This fix moves exec bit checking so that it's performed before dumping file contents. Added test to check executable bit removal.

convert: handle empty intial commits while converting to svn Svn commit generation code skips empty commits, returning the parent. Skipping the root commit must return None instead. Added test to check skipping of empty commits.

branchmap: encapsulate cache updating in the map itself Rather than have a repository update the cache, move handling of cache updates into the branchmap module, in the form of a custom mapping class. This makes later performance improvements easier to handle too. Differential Revision: https://phab.mercurial-scm.org/D5638

tests: fix regression tests failing on CentOS 7 Differential Revision: https://phab.mercurial-scm.org/D5877

packaging: modify rc detection to work with X.Yrc instead of X.Y-rc rc detection on CentOS failed without this change, resulting in upgrades from 4.9rc to 4.9 not working (4.9rc was considered more recent than 4.9). Differential Revision: https://phab.mercurial-scm.org/D5876

context: replace repeated "self._repo.dirstate" by "ds" variable Differential Revision: https://phab.mercurial-scm.org/D5889

context: delete unused undelete() Maybe it's been unused since c8e2a5ea7062 (mq: avoid data loss upon qfold + qmv (issue3058), 2011-10-20), maybe not. Differential Revision: https://phab.mercurial-scm.org/D5888

diffordiffstat: avoid looking up contexts twice I'm not worried about performance; this is just simpler. Differential Revision: https://phab.mercurial-scm.org/D5890

fsmonitor: rename new verbose config knob The config knob was introduced in this release cycle under the old extension name, rename it before it is part of a release. Differential Revision: https://phab.mercurial-scm.org/D5880

tests: stabilize test-extdiff.t on Windows The test harness only wanted to drop the (windows !) lines, which also means the actual output matched the (no-windows !) lines. So drop those annotations too. I suspect if the output of the affected tests was actually collected on Windows, things were quoted because TEMPDIR contained a `~` in MSYS. Typically that happens when the username is 9 (8?) or more characters. I explicitly set TEMP and TMP to something short like "C:\temp" to avoid this, because otherwise there are a bunch of failures like this in other tests.
