context: rename troubled into isunstable As we changed the meaning of unstable between the old vocabulary and the new one, we can't reuse the unstable method name at the risk of breaking extensions calling unstable and getting a wrong result.

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. I considered adding a strip api to the manifestlog, so other implementations could make it a no-op there, but it seems like strip might be unique to the revlog implementation, and therefore shouldn't be present on the generic api. Differential Revision: https://phab.mercurial-scm.org/D292

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. I considered moving the collect changes function onto the manifestlog itself, so it would be behind the abstraction, but since the store we're building doesn't even have the concept of strip, embeding that concept in the manifestlog api seemed odd.

bundle2: convert ints to strings using pycompat.bytestring() Fixes some Python 3 regressions. We don't use %d here because the part id is actually an Optional[int].

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.

repo: skip invalidation of changelog if it has 'delayed' changes (API) The changelog object can store recently added revisions in memory until the transaction is committed.

httppeer: make several instance attributes internal (API) Peer instances are supposed to conform to a well-defined API so consumers can be agnostic about the underlying peer type. To reinforce this, this commit renames a handful of instance attributes on httpeer so they no longer have a "public" name. Differential Revision: https://phab.mercurial-scm.org/D268

httppeer: remove unused handler attribute The consumer of this attribute was removed by b6bd4ee6ed85 in 2008. Differential Revision: https://phab.mercurial-scm.org/D267

localrepo: remove unused requirements attributes on localpeer (API) The previous changeset removed the last consumer of requirements. I'm not sure when supportedformats became unused. But I couldn't find any obvious instances where it is being used. It likely stems from peers being derived from repository instances several years ago and is a holdover from that day. Differential Revision: https://phab.mercurial-scm.org/D266

exchange: access requirements on repo instead of peer As part of formalizing the peer interface, I audited for attribute accesses for non-internal names to find API violations. This uncovered the code changed in this commit. localpeer.requirements is just an alias to the repo's requirements attribute. So, change the code to get the data from the source instead of relying on a one-off attribute in the localpeer type. Differential Revision: https://phab.mercurial-scm.org/D265

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

http: add a test of actually pushing with httppostargs This was previously untested. Sigh. Differential Revision: https://phab.mercurial-scm.org/D230

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.

status: avoid recursing into ignored directory with "--terse u" Let "isignoreddir" function first check that supplied directory is itself ignored before walking recursively into its content. Otherwise, the command is awfully slow when one has an ignored directory with a lot of content. Update and rephrase function docstring accordingly.

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. One can turn that on by following config: [push] pushvars.server = true This patch also adds the test for the extension. Differential Revision: https://phab.mercurial-scm.org/D210

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.
