tests: make test-worker.t pass on py2 I broke the py2 version in https://phab.mercurial-scm.org/D9287 because the `WorkerError.__bytes__()` (or `.__str__()`?) output was different in py2 compared to py3. Part of the problem was that I didn't propagate the status code that was passed in to the superclass so it could get printed. This patch fixes that. I don't know how it worked on py3 before this patch... I also added the usual `__bytes__ = _tobytes` override for good measure. It doesn't seem to be needed for tests to pass, though.

log: add bookmark option to "hg log" Before pushing a bookmark with "hg push origin -B 'my-topic'", it is useful to inspect the list of commits that are ancestors of the bookmark. By relying on scmutil.bookmarkrevs(), "hg log -B topic" has the same bookmark semantics found in other commands like hg export, hg email, hg strip.

extensions: gracefully warn when doing min version check with no local version After doing a `make clean`, I started getting cryptic failures to import extensions with the `minimumhgversion` attribute on py3: *** failed to import extension evolve: '>' not supported between instances of 'int' and 'NoneType' *** failed to import extension topic: '>' not supported between instances of 'int' and 'NoneType' This now handles the `(None, None)` tuple before comparing, and disables the extension with the same friendly message as in py2.

make: switch the PYTHON default to `py.exe -3` on Windows Python3 _is_ named `python.exe` on Windows, but that isn't necessarily on PATH when installing from python.org. I do happen to have a python.exe on PATH in `$LOCALAPPDATA/Microsoft/WindowsApps`, but it appears to be 0 bytes (likely because of permission issues), and doesn't run: $ python -V - Cannot open Pulkit hit the same error as I did though, so it isn't just my system: $ make -C . local make: Entering directory `/home/Dell/repos/hg-committed` python setup.py \ build_py -c -d . \ build_ext -i \ build_hgexe -i \ build_mo - Cannot openmake: *** [local] Error 1 The `py.exe` dispatcher lives in the Windows directory (so it is on PATH), looks up the python.org installation, and invokes that interpreter directly. I get a warning with py39, but if it's our issue, it was an existing one: $ make -C .. local make: Entering directory `/c/Users/Matt/hg' py -3 setup.py \ build_py -c -d . \ build_ext -i \ build_hgexe -i \ build_mo C:\Users\Matt\AppData\Local\Programs\Python\Python39\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first. warnings.warn( The end result is a py3 based hg.exe that annoyingly won't run because it can't find python39.dll. It will run tests (the ones without the `python3` shbang line anyway), because the test runner adjusts PATH to include the python running it.

heptapod-ci: hosting base image on registry.heptapod.net We are now touching the rate limits of Docker Hub.

errors: use exit code 10 for parse errors Now that `ParseError`s raised while reading the config file has been converted into `ConfigError`s, the remaining parse errors should all be "input errors" (i.e. exit code 10), according to https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. Differential Revision: https://phab.mercurial-scm.org/D9332

errors: raise ConfigError on failure to parse config file This replaces two raises of `ParseError` by `ConfigError`, which makes it so we get the desired exit code when `ui.detailed-exit-code` is enabled. Because the exceptions include a location, I had to add that to `ConfigError` as well. I considered making `ConfigError` a subclass of `ParseError`, but it doesn't feel like it quite passes the "is-a" test. I used "config error: " as prefix for these errors instead of the previous "hg: parse error: ", which seems a little less accurate now (and, as I've said before, I don't know what the "hg: " part is supposed to signify anyway). I can easily be convinced to change the prefix to something else (including "abort: "). Some of the exceptions raised here mean that we fail to even load the `ui` object in the `dispatch` module. When that happens, we don't know to use detailed exit codes, so some tests (e.g. `test-hgrc.t`) still see exit code 255. I'll try to get back to that later. It should be possible to give detailed exit codes if at least part of the config can be read (e.g. when the system-wide one enables detailed exit codes and the user's config fails to parse).

histedit: don't crash if commit message is empty If the commit message is empty, histedit will crash before this patch because it assumes that `summary.splitlines()` is non-empty. One of our users at work ran into this crash for a commit that was created by an internal system. I don't think we have a good way of testing this because it's hard to create a commit with an empty commit message. I've added a comment to help prevent regressions.

copies: cache the ancestor checking call when tracing copy A good share of the time spent in this function is spent doing ancestors checking. To avoid spending time in duplicated call, we cache the result of calls. In the slower case, this provide a quite significant performance boost. Below are the result for a set of selected pairs (many of them pathological): (And further down is another table that summarize the current state of filelog based vs changeset base copy tracing) The benchmark have been configured to be killed after 6 minutes of runtime, which mean that any detect slower than 2 minutes will be marked as "killed". This drop some useful information about how much slower these case are… but also prevent 99% of the benchmark time to be spent on case that can be labelled "very slow" anyway.

of the current "filelog centric" algorithm, with the "changeset centric" one, we just modified. The changeset centric algorithm is a significant win in many scenario, but they are still various cases where it is quite slower. When many revision has to be considered the cost of retrieving the copy information, creating new dictionaries, merging dictionaries and checking if revision are ancestors of each other can slow things down. The rest of this series, will introduce a rust version of the copy tracing code to deal with most of theses issues.

config: clean up message about ignored untrusted config The error message relied on Python's default formatting of arguments to an Exception's constructor. Let's try to make it a little more readable for users. Differential Revision: https://phab.mercurial-scm.org/D9352

tests: use new ParseError.format() in test-trusted.py Differential Revision: https://phab.mercurial-scm.org/D9351

errors: make ParseError a subtype of Abort I didn't plan this before, but the previous two changes made it really easy to make `ParseError` a subtype of `Abort`. It seems obvious with hindsight that I *should* have planned it :) Differential Revision: https://phab.mercurial-scm.org/D9350

tests: make doctests not depend on str(ParseError()) format `ParseError` implements `__bytes__`, but it doesn't implement `__str__`, so it gets the default `__str__` implementation. The next patch will make it so `ParseError` gets a `__str__` implementation, which changes the format slightly. This prepares by making us not depend on the format. Differential Revision: https://phab.mercurial-scm.org/D9349

errors: format "abort: " text in a new Abort.format() method This remove some duplication we had. Differential Revision: https://phab.mercurial-scm.org/D9348

errors: make formatparse() an instance method on ParseError It's just a little simpler this way. Don't ask me what the "hg: " prefix signifies to the user, I just left it as it was. I think we should consider changing the prefixes later (maybe always use "abort: ", or maybe use more specific prefixes in general). Differential Revision: https://phab.mercurial-scm.org/D9347

errors: create "similarity hint" for UnknownIdentifier eagerly in constructor No code wanted to do anything but to produce a hint from it anyway, so we might as well just store the hint in the exception (which already extended `Hint`). That way we can easily convert it to a `ConfigException` when it's parsing of configuration that fails. I was wondering if the purpose of lazily creating the string was so we don't create it in cases where it won't get printed anyway. However, I couldn't find any places where that could happen. If we do find such places, we could instead revert to making it lazy but add a function on `UnknownIdentifier` for creating the hint string. I dropped the comment saying "make sure to check fileset first, as revset can invoke fileset", which was added in 4e240d6ab898 (dispatch: offer near-edit-distance suggestions for {file,rev}set functions, 2015-01-26). I couldn't figure out what it meant. The author of that patch also did not remember the reason for it. Perhaps changes that have happened since then made it so it no longer matters. Differential Revision: https://phab.mercurial-scm.org/D9346

errors: move similarity_hint() to error module I want to be able to reuse it from `UnknownIdentifier`'s constructor. Moving it results in a new import of `difflib` in the `error` module. There was a comment at the top of `error.py` saying "Do not import anything but pycompat here, please", which was added (except for the "pycompat" bit) in 08cabecfa8a8 (errors: move revlog errors, 2009-01-11). I don't know the reason for the comment. I'm guessing the point was to not make the module depend on other Mercurial modules. If that was it, then importing `difflib` should be fine. Sorry about the churn (I moved this code from the `dispatch` module to the `scmutil` module very recently). Differential Revision: https://phab.mercurial-scm.org/D9345

errors: morph reportsimilar() into similarity_hint() The next step is to eagerly create the hint in `UnknownIdentifier`'s constructor. Differential Revision: https://phab.mercurial-scm.org/D9344

errors: restructure formatparse() to clarify conditions a bit The `similar` list will be calculated only for `error.UnknownIdentifier`. It was then printed only if `inst.location is None`, which is true for that exception type, but it's an indirect condition to rely on. Also, it looked from the code like it could both report similarities and print a hint. That would be a little awkward because the similarity report looks similar to the hint (both are printed within parentheses). I also added a `elif` to clarify that. I plan to refactor this more coming patches so the similarity report actually is a hint. Differential Revision: https://phab.mercurial-scm.org/D9343

transaction: split new files into a separate set Journal entries with size 0 are common as they represent new revlog files. Move them from the dictionary into a set as the former is more dense. This reduces peak RSS by 70MB for the NetBSD test repository with around 450k files under .hg/store. Differential Revision: https://phab.mercurial-scm.org/D9278

transaction: change list of journal entries into a dictionary The transaction object used to keep a mapping table of path names to journal entries and a list of journal entries consisting of path and file offset to truncate on rollback. The offsets are used in three cases. repair.strip and rollback process all of them in one go, but they care about the order. For them, it is perfectly reasonable to read the journal back from disk as both operations already involve at least one system call per journal entry. The other consumer is the revlog logic for moving from inline to external data storage. It doesn't care about the order of the journal and just needs to original offset stored. Further optimisations are possible here to move the in-memory journal to a set(), but without memoisation of the original revlog size this could turn it into O(n^2) behavior in worst case when many revlogs need to migrated. Differential Revision: https://phab.mercurial-scm.org/D9277

transaction: rename find to findoffset and drop backup file support transaction.find used to support access to both the regular file and backup file list. They have different formats, so any consumer has to be aware of the difference alredy. There is no in-core consumer for the backup file access, so don't provide it. Differential Revision: https://phab.mercurial-scm.org/D9276

transaction: drop per-file extra data support At the moment, transactions support an optional extra data argument for all files to be stored in addition to the original offset. This is used in core only by the revlog inline to external data migration. It is used to memoize the number of revisions before the transaction. That number of can be computed during the walk easily, so drop the requirement. Differential Revision: https://phab.mercurial-scm.org/D9275

templates: define a {onelinesummary} keyword It is sometimes useful to be able to use the configured `command-template.oneline-summary` in higher-level templates. For example, I would like to use it in an internal template that lists commits in a "review unit" (kind of a pull request). This patch adds support for that. We may want to define a way of formatting a context using a command-specific override (from `command-templates.oneline-summary.<command>`), but that will have to be a template function instead. I don't plan to do that, but I'm mentioning it now in case reviewers would prefer that we use a no-arg function (i.e. `{onelinesummary()}`) already today to prepare for that.

rust-status: don't bubble up os errors, translate them to bad matches In the rare cases when either the OS/filesystem throws an error on an otherwise valid action, or because a path is not representable on the filesystem, or because of concurrent actions in the filesystem, we want to warn the user about said path instead of bubbling up the error, causing an exception to be raised in the Python layer.

I don't think I realized that the output I modified was being put in a commit message template. The result was that if you have coloring enabled, you get colors in the commit template. This patch show that. The test is unfortunately pretty verbose (like most other `hg split` tests) and shows a bunch of irrelevant "color codes" (templater labels).

chgserver: backport py3 buffered I/O workarounds from procutil I've recently switched to new machine and I found chg's stdout is fully buffered. Even though chg server is a daemon process, it inherits the environment where the chg client originally forked the server. This means the server's stdout might have been wrapped by LineBufferedWrapper. That's why we need to do wrap/unwrap in both ways. The "if" condition in _restoreio() looks weird, but I'm not willing to clean things up because stdio behavior is fundamentally different between py2 and py3, and py2 support will be dropped anyway.

chg: reset errno prior to calling strtol() Otherwise we can't figure out if the last strtol() invocation failed or not.

chg: do not close dir fd while iterating It works so long as the dp is the last entry, but readdir(dp) would fail with EBADF. Let's not do that and close the dir fd explicitly.

chg: show debug message for each fd to be closed It helps debugging. The number of file descriptors should be small in most cases, so the console output wouldn't get bloated even with CHG_DEBUG=1.

errors: catch urllib errors specifically instead of using safehasattr() Before this patch, we would catch `IOError` and `OSError` and check if the instance had a `.code` member (indicates `HTTPError`) or a `.reason` member (indicates the more generic `URLError`). It seems to me that can simply catch those exception specifically instead, so that's what this code does. The existing code is from fbe8834923c5 (commands: report http exceptions nicely, 2005-06-17), so I suspect it's just that there was no `urllib2` (where `URLError` lives) back then. The old code mentioned `SSLError` in a comment. The new code does *not* try to catch that. The documentation for `ssl.SSLError` says that it has a `.reason` property, but `python -c 'import ssl; print(dir(ssl.SSLError("foo", Exception("bar"))))` doesn't mention that property on either Python 2 or Python 3 on my system. It also seems that `sslutil` is pretty careful about converting `ssl.SSLError` to `error.Abort`. It also is carefult to not assume that instances of the exception have a `.reason`. So I at least don't want to catch `ssl.SSLError` and handle it the same way as `URLError` because that would likely result in a crash. I also wonder if we don't need to handle it at all (because `sslutil` might handle all the cases). It's now early in the release cycle, so perhaps we can just see how it goes?

test-filecache: use sys.executable to call python As was mentioned in c102b704edb5, test scripts calling 'python' or 'python3' might use the wrong python. For test-filecache.py, this causes a failed test on CentOS 7. Differential Revision: https://phab.mercurial-scm.org/D9295

pyoxidizer: default to one-file binary on non-Windows platforms Windows has some extra constraints that require a multi-file install, but we expect folks to use an MSI or similar installer there so it's less of a big deal. Differential Revision: https://phab.mercurial-scm.org/D9289

global: use python3 in shebangs Python 3 is the future. We want Python scripts to be using Python 3 by default. This change updates all `#!/usr/bin/env python` shebangs to use `python3`. Does this mean all scripts use or require Python 3: no. In the test environment, the `PATH` environment variable in tests is updated to guarantee that the Python executable used to run run-tests.py is used. Since test scripts all now use `#!/usr/bin/env python3`, we had to update this code to install a `python3` symlink instead of `python`. It is possible there are some random scripts now executed with the incorrect Python interpreter in some contexts. However, I would argue that this was a pre-existing bug: we should almost always be executing new Python processes using the `sys.executable` from the originating Python script, as `python` or `python3` won't guarantee we'll use the same interpreter.

errors: set detailed exit code to 20 for locking errors This is per https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. Differential Revision: https://phab.mercurial-scm.org/D9242

errors: introduce InputError and use it from commands and cmdutil This patch introduces a `InputError` class and replaces many uses of `error.Abort` by it in `commands` and `cmdutil`. This is a part of https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. There will later be a different class for state errors (to raise e.g. when there's an unfinished operation). It's not always clear when one should report an input error and when it should be a state error. We can always adjust later if I got something wrong in this patch (but feel free to point out any you notice now). Differential Revision: https://phab.mercurial-scm.org/D9167

errors: add config that lets user get more detailed exit codes This adds an experimental config that lets the user get more detailed exit codes. For example, there will be a specific error code for input/user errors. This is part of https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. I've made the config part of tweakdefaults. I've made the config enabled by default in tests. My reasoning is that we want to see that each specific error case gives the right exit code and we don't want to duplicate all error cases in the entire test suite. It also makes it easy to grep the `.t` files for `[255]` to find which cases we have left to fix. The logic for the current exit codes is quite simple, so I'm not too worried about regressions there. I've added a test case specifically for the "legacy" exit codes. I've set the detailed exit status only for the case of `InterventionRequired` and `SystemExit` for now (the cases where we currently return something other than 255), just to show that it works. Differential Revision: https://phab.mercurial-scm.org/D9238

worker: raise exception instead of calling sys.exit() with child's code When a worker process returns an error code, we would call `sys.exit()` with that exit code on the main process. The `SystemExit` exception would then get caught in `scmutil.callcatch()`, which would return that error code. The comment there says "Commands shouldn't sys.exit directly", which I agree with. This patch changes it so we raise a specific exception when a worker fails so we can catch instead. I think that means that `SystemExit` is now always an internal error. (I had earlier thought that this call to `sys.exit()` was from within the child process until Matt Harbison made me look again, so thanks for that!)

makefile: use Python 3 by default (BC) This change is long overdue IMO. .. bc:: Makefile now uses `python3` instead of `python` by default on non-Windows platforms. This means Mercurial will be built and run with Python 3 instead of Python 2.7 by default. To continue using Python 2, set the PYTHON variable. e.g. `make install PYTHON=python2.7`. Differential Revision: https://phab.mercurial-scm.org/D7258

hgweb: don't call sys.exit() in httpservice.run() If I'm reading the code correctly, `mercurial.server.createservice()` can return an hgweb service or one of three types of command server services. The caller then calls `mercurial.server.runservice()`, passing it the returned service's run method. Only the hgweb service was calling `sys.exit()`. It has been that way since 8d44649df03b (refactor ssh server., 2006-06-04). That commit message doesn't provide any explanation. Let's clean up and have the code follow the usual return path into the `dispatch` module. After this patch, there should be no remaining places left where we call `sys.exit()` except for valid uses in the `dispatch` and `worker` modules. Differential Revision: https://phab.mercurial-scm.org/D9272

serve: simply return instead of calling sys.exit() in `hg serve --stdio` The shouldn't be a reason to call `sys.exit()` instead of letting the code return normally. I've remove the call in both `hg serve` and `hg debugserve`. Differential Revision: https://phab.mercurial-scm.org/D9271

httpservice: move sys.exit() out of serve_forever() This is a simple refactoring to show the callers of the method, so it's easier to reason about the impact of removing the `sys.exit()` calls in subsequent patches. Differential Revision: https://phab.mercurial-scm.org/D9270

copies: handle more cases where a file got replaced by a copy This patch fixes the changeset-centric version in a pretty straight-forward way. It fixes it to automatically resolve the conflict, which is better than resulting in a modify/delete conflict as it was before b4057d001760 (merge: when rename was made on both sides, use ancestor as merge base, 2020-01-22). I'll leave it for later to test and explicitly handle cases where files have been renamed to the same target on different sides of the merge. Differential Revision: https://phab.mercurial-scm.org/D8653

tests: test more cases where a file got replaced by a copy This adds a test where a file is modified on one branch and is renamed onto another file in another branch. That should ideally be automatically resolved (by propagating the modification to the rename destination). Alternatively, it could be considered a modify/delete conflict. It should at least not be automatically resolved by ignoring the modification. However, that is what actually happens with the changeset-centric algorithm since I broke it in b4057d001760 (merge: when rename was made on both sides, use ancestor as merge base, 2020-01-22). Before that commit, it resulted in a modify/delete conflict. The filelog-centric algorithm was broken already before that commit. Differential Revision: https://phab.mercurial-scm.org/D8652

unionrepo: don't insert index tuples with None as int field None is not a valid size. Use -1 as placeholder instead. This will be necessary when the index starts enforcing type correctness. Differential Revision: https://phab.mercurial-scm.org/D9161

bundlerepo: don't insert index tuples with full nodes as linkrev The index format has a documented format and latter changes will start to enforce the field types. The bundlerepo uses full nodes for the linkrev field when it should be using revision numbers. Use the link mapping to resolve them, except in the special case of self-references. Those are actually indications of a missing linkrev. Differential Revision: https://phab.mercurial-scm.org/D9160

commit: warn the user when a commit already exists Sometimes, a commit will result in an exact match of a preexisting commit, and if that commit isn't a branch head, hg will incorrectly note that it created a new head. Instead, we should warn the user that commit already existed in the repository. In practice, this bug is rather uncommon, and will only occur when the usr explicitly sets the date.

revlog: don't cache parsed tuples in the C module A cached entry creates ~8 Python objects per cached changeset, which comes to around 200 Bytes per cached changeset on AMD64. Especially for operations that touch a lot of changesets, that can easily sum up to more than a 100MB of memory. Simple tests on large repositories show <2% runtime penalty for ripping out the cache, even for cache heavy operations like "hg log" for all revisions.

fix: only check for obsolete commits in the --rev case With both `--all` and `--source`, we already exclude obsolete revisions in the revset, so there's no need to call `checkfixablectx()` in those cases. Differential Revision: https://phab.mercurial-scm.org/D9227

fix: don't include obsolete descendants with -s The `-s/--source` option is for regular users (`-r` is there for power users). If there are obsolete commits that are descendants of the given revision(s), then they almost definitely should just be left alone. That's what `hg rebase` does as well. So this patch makes it so we skip obsolete commits (including those in the input set itself). Differential Revision: https://phab.mercurial-scm.org/D9226

templates: include all non-branch namespaces in default one-line summary I left out branches and custom namespaces on purpose from D9252 because I figured that people like us (Google) who have custom namespaces can also have custom configs. However, I just realized that this makes everyone with the topic extension lose the topic they've had in rebase output for a long time (ever since someone was nice enough to add it in D741). Sorry about the churn. The more generic template couldn't easily keep the "log.bookmark" label in the template because the namespace is called "bookmarks" (plural). That means that we can't be compatible with users' existing configs for "log.bookmark", so I decided to change the labels to be in a brand-new "oneline-summary" namespace.
