morestatus: move fb extension to core by plugging to `hg status --verbose` morestatus extension in fbext use to show more context about the state of the repo like the repository is in a unfinished merge state, or a rebase is going on, or histedit is going on, listing the files which need to be resolved and also suggesting ways to handle the situation. This patch moves the extension directly to core by plugging it into the --verbose flag of the status command. So now if you are in any unfinished state and you do hg status -v, it will show you details and help related to the state. The extension in fbext also shows context about unfinished update state which is not ported to core as that plug in hooks to update command which need to be tackled somewhat differently. The following configuration will turn the behaviour on by default [commands] status.verbose = 1 You can also skip considering some states like bisect as follows: [commands] status.skipstates=bisect This patch also adds test for the feature. .. feature:: ``hg status -v`` can now show unfinished state. For example, when in an unfinished rebase state, ``hg status -v`` might show:: # The repository is in an unfinished *rebase* state. # No unresolved merge conflicts. # To continue: hg rebase --continue # To abort: hg rebase --abort Differential Revision: https://phab.mercurial-scm.org/D219

bundle2: fix transaction availability detection Changeset 5fc4ddfbe626 introduce more complex logic around 'bundleoperation.gettransaction'.

sshpeer: make instance attributes and methods internal Peer types are supposed to conform to a formal interface defined by peer.peerrepository and wireproto.wirepeer. Every "public" attribute on *peer types makes it harder to understand what attributes are part of the interface and what are instance specific. This commit converts a number of "public" instance attributes and methods on sshpeer to internal so they can't be confused to be part of the peer API. The URL-related instance attributes were introduced in 876333a295ff in 2005. AFAICT most of them aren't used and could potentially be removed. But I kept them around anyway. I also reorded some code to make things slightly easier to read. .. api:: Rename attributes on sshpeer to reflect peer API Differential Revision: https://phab.mercurial-scm.org/D331

peer: remove non iterating batcher (API) The last use of this API was removed in b6e71f8af5b8 in 2016. While not formally deprecated, as of the last commit the code is no longer explicitly tested. I think the new API has existed long enough for people to transition to it. I also have plans to more formalize the peer API and removing batch() makes that work easier. I'm not convinced the current client-side API around batching is great. But it's the best we have at the moment. .. api:: remove peer.batch() Replace with peer.iterbatch(). Differential Revision: https://phab.mercurial-scm.org/D320

wireproto: overhaul iterating batcher code (API) The remote batching code is difficult to read. Let's improve it. As part of the refactor, the future returned by method calls on batchiter() instances is now populated. However, you still need to consume the results() generator for the future to be set. But at least now we can stuff the future somewhere and not have to worry about aligning method call order with result order since you can use a future to hold the result. Also as part of the change, we now verify that @batchable generators yield exactly 2 values. In other words, we enforce their API. The non-iter batcher has been unused since b6e71f8af5b8. And to my surprise we had no explicit unit test coverage of it! test-batching.py has been overhauled to use the iterating batcher. Since the iterating batcher doesn't allow non-batchable method calls nor local calls, tests have been updated to reflect reality. The iterating batcher has been used for multiple releases apparently without major issue. So this shouldn't cause alarm. .. api:: @peer.batchable functions must now yield exactly 2 values Differential Revision: https://phab.mercurial-scm.org/D319

wireproto: remove support for local results in @batchable (API) @peer.batchable decorated generator functions have two forms: yield value, None and yield args, future yield value These forms have been present since the decorator was introduced. There are currently no in-repo consumers of the first form. So this commit removes support for it. Note that remoteiterbatcher.submit() asserts the 2nd form. And b6e71f8af5b8 removed the last user of remotebatcher, forcing everyone to remoteiterbatcher. So anything relying on this in the wild would have been broken since b6e71f8af5b8. .. api:: @peer.batchable can no longer emit local values Differential Revision: https://phab.mercurial-scm.org/D318

wireproto: properly implement batchable checking remoteiterbatcher (unlike remotebatcher) only supports batchable commands. This claim can be validated by comparing their implementations of submit() and noting how remoteiterbatcher assumes the invoked method has a "batchable" attribute, which is set by @peer.batchable. remoteiterbatcher has a custom __getitem__ that was trying to validate that only batchable methods are called. However, it was only validating that the called method exists, not that it is batchable. This wasn't a big deal since remoteiterbatcher.submit() would raise an AttributeError attempting to `mtd.batchable(...)`. Let's fix the check and convert it to ProgrammingError, which may not have been around when this was originally implemented. Differential Revision: https://phab.mercurial-scm.org/D317

largefiles: remove remotestore.batch() This method was added in 9e1616307c4c. AFAICT it didn't do anything at inception. If it did, there was no test coverage for it because changing it to raise doesn't fail any tests at that revision. b6e71f8af5b8 later refactored all remote.batch() calls to remote.iterbatch(). So if this was somehow used, it isn't called any more because there are no calls to .batch() remaining in the repo. I suspect the original patch author got confused by the distinction between the peer/remote interface and the largefiles store. The lf store is a gateway to a peer instance. It exposes additional lf-specific methods to execute against a peer. However, it is not a peer and doesn't need to implement batch() because peer itself does that.

histedit: check first changeset for verb "roll" or "fold" (issue5498) If someone changes "pick" to "roll" or "fold" for the first changeset in a histedit rule Mercurial could remove a wrong changeset if the phase is non-public. roll or fold for the first changeset should be invalid.

encoding: drop circular import by proxying through '<policy>.charencode' I decided not to split charencode.c to new C extension module because it would duplicate binary codes unnecessarily.

policy: reroute proxy modules internally This allows us to split encoding functions from pure.parsers without doing that for cext.parsers. See the next patch for why.

cext: modernize charencode.c to use Py_ssize_t

cext: factor out header for charencode.c This merges a part of util.h with the header which should exist for charencode.c.

cext: split character encoding functions to new compilation unit This extracts charencode.c from parsers.c, which seems big enough for me to hesitate to add new JSON functions. Still charencode.o is linked to parsers.so to avoid duplication of binary codes.

cext: move _dict_new_presized() to header Prepares for splitting encoding functions from parsers.c.

ui: restore behavior to ignore some I/O errors (issue5658) e9646ff34d55 and 1bfb9a63b98e refactored ui methods to no longer silently swallow some IOError instances. This is arguably the correct thing to do. However, it had the unfortunate side-effect of causing StdioError to bubble up to sensitive code like transaction aborts, leading to an uncaught exceptions and failures to e.g. roll back a transaction. This could occur when a remote HTTP or SSH client connection dropped. The new behavior is resulting in semi-frequent "abandonded transaction" errors on multiple high-volume repositories at Mozilla. This commit effectively reverts e9646ff34d55 and 1bfb9a63b98e to restore the old behavior. I agree with the principle that I/O errors shouldn't be ignored. That makes this change... unfortunate. However, our hands are tied for what to do on stable. I think the proper solution is for the ui's behavior to be configurable (possibly via a context manager). During critical sections like transaction rollback and abort, it should be possible to suppress errors. But this feature would not be appropriate on stable.

tests: test behavior of IOError during transactions (issue5658) ui._write(), ui._write_err(), and ui.flush() all trap IOError and re-raise as error.StdioError. If a caller doesn't catch StdioError when writing to stdio, it could bubble all the way to dispatch. This commit adds tests for I/O failures around various transaction operations. The most notable badness is during abort. Here, an uncaught StdioError will result in incomplete transaction rollback, requiring an `hg rollback` to recover. This can result in a client "corrupting" a remote repo via terminated HTTP and SSH socket.

repair: move manifest strip to a separate function This moves manifest stripping to a separate function so implementations of the manifest that don't support stripping can replace this function with a no-op.

repair: refactor broken linkrev collection This refactors broken linkrev collection such that manifest collection is in a separate function. This allows extensions to replace the manifest collection with a non-revlog oriented version.

test-rebase: add a brute force test Rebase is becoming more complex and it looks like a good idea to try some brute force enumeration to cover cases that are hard to find manually. Using brute force to generate repos in different shapes and enumerating the rebase source and destination would generate too many cases that takes too long to compute. This patch limits the "brute force" to only the "rebase source" part. Repo and destination are still manual. The added test cases are crafted manually to reveal some behaviors that are not covered by other tests: - "revlog index out of range" crash - after rebase, p1 == p2, p2 != null - "nothing to merge" abort In the future we might want to add more tests here. For now I'm more interested in revealing interesting behaviors in a minified way. I tried some more complex cases but didn't find other interesting behaviors.

exchange: drop support for lock-based unbundling (BC) Locking over the wire protocol and the "addchangegroup" wire protocol command has been deprecated since e8c4f3d3df8c, which was first part of Mercurial 0.9.1. Support for handling these commands from sshserver was dropped in 9f6e0e7ef828 in 2015, effectively locking out pre 0.9.1 clients from new servers. However, client-side code for calling lock and addchangegroup is still present in exchange.py and the various peer classes to facilitate pushing to pre 0.9.1 servers. The lock-based pushing mechanism is extremely brittle. 0.9.1 was released in July 2006 and I highly doubt anyone is still running such an ancient version of Mercurial on a server. I'm about to refactor the peer API and I don't think it is worth keeping support for this ancient protocol feature. So, this commit removes client support for the lock-based pushing mechanism. This means modern clients will no longer be able to push to pre 0.9.1 servers. Differential Revision: https://phab.mercurial-scm.org/D264

filemerge: move decorator definition for internal merge tools to registrar This patch also adds extra loading entry for internal merge tools to extensions.py, for similarity to other decorators defined in registrar.py. This patch uses "internalmerge" for decorator class name, instead of original "internaltool", because the latter is too generic. BTW, after this patch, 4-spaces indentation is added to the 1st line of internal merge tool description docstring, and this may make already translated entries in *.po fuzzy. Even though this indentation is required for "definition list" in reST syntax, absence of it has been overlooked, because help.makeitemsdoc() forcibly inserts it at generation of online help. But this forcible insertion causes formatting issue (I'll send another patch series for this). Therefore, this additional indentation should be reasonable.

releasenotes: add similarity check function to compare incoming notes It is possible that the incoming note fragments have some similar content as the existing release notes. In case of a bug fix, we match for issueNNNN in the existing notes. For other general cases, it makes use of fuzzywuzzy library to get a similarity score. If the score is above a certain threshold, we ignore the fragment, otherwise add it. But the score might be misleading for small commit messages. So, it uses similarity function only if the length of string (in words) is above a certain value. The patch adds tests related to its usage. But it needs improvement in the sense of combining incoming notes. We can use interactive mode for adding notes. Maybe we can do this if similarity is under a certain range.

releasenotes: add import check for fuzzywuzzy This patch adds the has_fuzzywuzzy for import check of external dependency fuzzywuzzy.

run-tests: don't drop optional lines after a missing unconditional line The previous behavior was to bail out when hitting 'awol', so 'missing (?)' was also dropped.

run-tests: drop required (feature !) style lines when the output is missing Essentially, these were acting as a verbose (?) flag, since they weren't being dropped when required. Foozy has a nice description [1]. Basically, a couple more places needed to check the features before treating it as optional. I don't like how test-run-tests.py had to be hacked, but _hghave() can't be made a static method. The test change was a change while developing `debugssl`, prior to tightening up the cases where the message is printed, that this fix would have caught.

pushvars: move fb extension pushvars to core pushvars extension in fbext adds a --pushvars flag to push command using which one send strings to server which becomes environment variables there prepended with HG_USERVAR_. These variables can then be used to run hooks on the server. The extension is moved directly to core and unbundling of the strings and converting them to environment variables at server is disabled by default for security reasons.

phabricator: update diff property even if we choose not to create a new diff The diff property contains metadata like "HG Node". Previously we skip uploading a new diff if we are sure that the old patch and new patch have a same content. That has issues when a pusher adds an obsmarker using the old "HG Node" stored in the old diff. This patch adds logic to update the diff property so "HG Node" gets updated to prevent that issue. Differential Revision: https://phab.mercurial-scm.org/D229

phabricator: use Phabricator's last node information This makes it more strict when checking whether or not we should update a Differential Revision. For example, a) Alice updates D1 to content 1. b) Bob updates D1 to content 2. c) Alice tries to update D1 to content 1. Previously, `c)` will do nothing because `phabsend` detects the patch is not changed. A more correct behavior is to override Bob's update here, hence the patch. This also makes it possible to return a reaonsable "last node" when there is no tags but only `Differential Revision` commit messages. Test Plan: ``` for i in A B C; do echo $i > $i; hg ci -m $i -A $i; done hg phabsend 0:: # D40: created # D41: created # D42: created echo 3 >> C; hg amend; hg phabsend . # D42: updated hg tag --local --hidden -r 2 -f D42 # move tag to the previous version hg phabsend . # D42: skipped (previously it would be "updated") rm -rf .hg; hg init hg phabread --stack D42 | hg import - hg phabsend . # D42: updated hg tag --local --remove D42 hg commit --amend hg phabsend . # D42: updated (no new diff uploaded, previously it will upload a new diff) ``` The old diff object is now returned, which could be useful in the next patch.

py3: use bytes IO to write sample hgrc Unicode sucks. Stop using Text IO and manually convert line endings.

buildrpm: do not break in presence of custom user configs For example, if "hg log" was defined as an alias: # /etc/mercurial/hgrc [alias] log = log --graph the buildrpm script would be surprised by log messages formatted in unexpected ways, and bail out. This patch sets HGPLAIN, effectively resetting all the user configs, including log output, to a common state, making the build more predictable across all the possible environments.

sparse: treat paths as cwd-relative This commit makes it so sparse treats passed paths as CWD-relative, not repo-root-realive. This is a more intuitive behavior in my (and some other FB people's) opinion. This is breaking change however. My hope here is that since sparse is experimental, it's ok to introduce BCs. The reason (glob)s are needed in the test is this: in these two cases we do not supply path together with slashes, but `os.path.join` adds them, which means that under Windows they can be backslashes. To demonstrate this behavior, one could remove the (glob)s and run `./run-tests.py test-sparse.t` from MinGW's terminal on Windows.

match: expose some data and functionality to other modules This patch makes sure that other modules can check whether patterns are CWD-relative.

sparse: properly error out when absolute paths are used Current logic is misleading (it says it drops only absolute paths, but it actually drops all of them), not cross-platform (does not support Windows) and IMO just wrong (as it should just error out if absolute paths are given). This commit fixes it.

py3: convert arbitrary exception object to byte string more reliably Our exception types implement __bytes__(), which should be tried first. Do lossy encoding conversion as a last resort.

build: delay version computation on macOS builds The way HGVER is evaluated now, it'll be evaluated at the beginning of the make execution - with this change, it's evaluated when it gets to that command, at which point the version file it's looking for is sure to exist and be up-to-date.

color: remove warnings if term is not formatted (==dumb or !ui.formatted()) If the user sets color.mode=terminfo, and then runs in the shell inside of emacs (so TERM=dumb), the previous behavior was that it would warn about no terminfo entry for setab/setaf, and then warn about 'failed to set color mode to terminfo'. The first warning is silenced by carrying 'formatted' through to _terminfosetup, the second is silenced by using 'formatted' instead of ui.formatted(). If --color=on (or ui.color=always) is specified, this will still warn, since the formatted boolean is set to true in these cases. Differential Revision: https://phab.mercurial-scm.org/D223

rpms: add chg I'm not sure if there's a reason chg is not added by default. If not, I would like to propose adding in this patch. Differential Revision: https://phab.mercurial-scm.org/D220

tests: demonstrate crash when trying to rebase merge without its parents As the test case shows, when "hg rebase -d G -r 'B + D + F'" is run on the following graph, we crash with traceback. It's reasonable to fail because we can not easily produce a correct rebased F. The problem is what diff to apply to either the rebased B or the rebased D. We could potentially produce the result by e.g. applying the (F-D) diff to the rebased B and then applying the reverse (E-D) diff on top, but that could result in merge conflicts in each of those steps, which we don't have a way of dealing with. So for now, let's just add a test case to demonstrate that we crash (i.e. the AssertionError is clearly incorrect since the user can run into it).

tests: demonstrate broken rebase of merge with p1's successor in dest The fix in 8ede973597fd (rebase: handle successor targets (issue5198), 2016-04-11) only fixed the case where p2's successor was in the destination, and only when the successor was exactly the destination (i.e. not when the successor was an ancestor of it). This patch adds a test case for when p1's successor is in the destination. It adds another one for when the successor is an ancestor of the destination. To do that simply, it also rewrites the test case using drawdag. Differential Revision: https://phab.mercurial-scm.org/D211

bundle2: obtain repr() of exception in a python3-safe way This was exposed by other problems in bundle generation, but I'm not sure how to test it for now.

bundle2: use bytestr() instead of str() to convert part id to bytes This was exposed by trying to run previously-passing Python 3 tests.

bundle2: work around zip() being lazy in Python 3

bundle2: look for __next__ as well as next to identify iterators In Python 3, next is called __next__ and this was failing to catch some iterators.

bundle2: use modern Python division This was failing on Python 3 because the / was returning a float, which was then making the __mul__ on a bytes sad.

changegroup: wrap some ** expansions in strkwargs

obsolete: reuse _fm1metapair for computing _fm1metapairsize It's evaluated at import time, so it seems silly to not reuse the constant name.

setup: fix installing in a mingw environment The addition, in 9a4adc76c88a, of a hack for the MSVC compiler class was overwriting the original class for the Mingw32CCompiler class, leading to an error when the HackedMingw32CCompiler is instantiated.

osx: delay version computation on macOS builds Before this patch, HGVER would be evaluated at the beginning of the make execution, and would be unset because build/mercurial/ doesn't exist yet at that point. Now we compute the version after the `make install` run has completed. This is backported to stable from 8626b44516c1, but that revision had an error in the shell invocation syntax.
