convert: test clean p2 file missing 216fa1ba9993 introduced "clever" reuse of p2 but did that convert could fail with abort: f1@f73e02ae52c5: not found in manifest! when it tried to reuse a file from p2 but the file didn't exist there, for example because filemap changes. 5ca587348875 fixed that (using changes from a75d24539aba), but with a quite different reasoning and test case. Add another test that makes sure this case is covered too.

uescape: also encode non-printable char under 128 We were assuming everything under 128 was printable ascii, but there are a lot of control characters in that range that can't simply be included in json and other targets. We forcibly encode everything under 32, because they are either control char or oddly printable (like tab or line ending). We also add the hypothesis-powered test that caught this.

testing: add hypothesis fuzz testing Hypothesis a library for adding fuzzing over a range of structure data to your test suite: http://hypothesis.readthedocs.org/en/latest/ This adds the ability to build tests using Hypothesis within the Mercurial test suite. New tests and fixes using this helpers comes in later changesets.

i18n: look translation of both "DEPRECATED" and "(DEPRECATED)" up Since 44cc9f63a2f1, deprecated commands, options and so on are detected by "(DEPRECATED)" instead of "DEPRECATED". "hg.pot" generated from recent source files doesn't contain msgid "DEPRECATED", and looking the translation of "DEPRECATED" up in up-to-date *.po files works incorrectly. But on the other hand, there are still old *.po files, which contain msgid "DEPRECATED" but not "(DEPRECATED)". Looking the translation of "(DEPRECATED)" up in such old *.po files also works incorrectly. This patch resolves this problem by looking translation of both "DEPRECATED" and "(DEPRECATED)" up. This should work correctly, because previous patch makes "deprecated" checker be applied only on translations, of which msgid contains exact "(DEPRECATED)" string. 'p.msgstr' examination in 'deprecatedsetup()' is needed to ignore untranslated entries. This also makes 'deprecatedpe.msgstr' examination in 'deprecated()' meaningless.

i18n: fix regexp pattern to detect translation for DEPRECATED Since 44cc9f63a2f1, deprecated commands, options and so on are detected by "(DEPRECATED)" instead of "DEPRECATED". Therefore, 'deprecated' checker in i18n/check-translation.py should check translation, of which msgid contains "(DEPRECATED)" instead of "DEPRECATED". At glance, it seems to do so, but it actually doesn't, because Python regexp treats "()" as grouping of patterns and "(DEPRECATED)" matches only against "DEPRECATED".

scmutil: abort if an empty revision is given to revpair() When using 'extdiff --patch' to check the changes in a rebase, 'precursors(x)' evaluated to an empty set because I forgot the --hidden flag, so the other revision was used as the replacement for the empty set. The result was the patch for the other revision was diffed against itself, and the tool saying there were no differences. That's misleading since the expected diff args were silently changed, so it's better to bail out. The other uses of scmutil.revpair() are commands.diff and commands.status, and it doesn't make sense to allow an empty revision there either. The code here was suggested by Yuya Nishihara.

packaging: rework version detection and declaration (issue4912) Previously the -rc in our rc tags got dropped, meaning that those packages looked newer to the packaging system than the later release build. This rectifies the issue, though some damage may already have been done on 3.6-rc builds. I'm mostly cargo-culting the RPM version format - there don't appear to be rules for RPM about how to handle this. Hopefully an RPM enthusiast can fix up what I've done as a followup.

hgweb: escape class keyword when used as a js object property (issue4913)

localrepo: discard objects in _filecache at transaction failure (issue4876) 'repo.invalidate()' deletes 'filecache'-ed properties by 'filecache.__delete__()' below via 'delattr(unfiltered, k)'. But cached objects are still kept in 'repo._filecache'. def __delete__(self, obj): try: del obj.__dict__[self.name] except KeyError: raise AttributeError(self.name) If 'repo' object is reused even after failure of command execution, referring 'filecache'-ed property may reuse one kept in 'repo._filecache', even if reloading from a file is expected. Executing command sequence on command server is a typical case of this situation (5c0f5db65c6b also tried to fix this issue). For example: 1. start a command execution 2. 'changelog.delayupdate()' is invoked in a transaction scope This replaces own 'opener' by '_divertopener()' for additional accessing to '00changelog.i.a' (aka "pending file"). 3. transaction is aborted, and command (1) execution is ended After 'repo.invalidate()' at releasing store lock, changelog object above (= 'opener' of it is still replaced) is deleted from 'repo.__dict__', but still kept in 'repo._filecache'. 4. start next command execution with same 'repo' 5. referring 'repo.changelog' may reuse changelog object kept in 'repo._filecache' according to timestamp of '00changelog.i' '00changelog.i' is truncated at transaction failure (even though this truncation is unintentional one, as described later), and 'st_mtime' of it is changed. But 'st_mtime' doesn't have enough resolution to always detect this truncation, and invalid changelog object kept in 'repo._filecache' is reused occasionally. Then, "No such file or directory" error occurs for '00changelog.i.a', which is already removed at (3). This patch discards objects in '_filecache' other than dirstate at transaction failure. Changes in 'invalidate()' can't be simplified by 'self._filecache = {}', because 'invalidate()' should keep dirstate in 'self._filecache' 'repo.invalidate()' at "hg qpush" failure is removed in this patch, because now it is redundant. This patch doesn't make 'repo.invalidate()' always discard objects in '_filecache', because 'repo.invalidate()' is invoked also at unlocking store lock. - "always discard objects in filecache at unlocking" may cause serious performance problem for subsequent procedures at normal execution - but it is impossible to "discard objects in filecache at unlocking only at failure", because 'releasefn' of lock can't know whether a lock scope is terminated normally or not BTW, using "with" statement described in PEP343 for lock may resolve this ? After this patch, truncation of '00changelog.i' still occurs at transaction failure, even though newly added revisions exist only in '00changelog.i.a' and size of '00changelog.i' isn't changed by this truncation. Updating 'st_mtime' of '00changelog.i' implied by this redundant truncation also affects cache behavior as described above. This will be fixed by dropping '00changelog.i' at aborting from the list of files to be truncated in transaction.

demandimport: fix TypeError when importing Python regex library (issue4920)

bundle2: attribute remote failures to remote (issue4788) Before bundle2, hook output from hook failures was prefixed with "remote: ". Up to this point with bundle2, the output was converted to the message to print in an Abort exception. This had 2 implications: 1) It was unclear whether an error message came from the local repo or the remote 2) The exit code changed from 1 to 255 This patch changes the handling of error:abort bundle2 parts during push to prefix the error message with "remote: ". This restores the old behavior. We still preserve the behavior of raising an Abort during bundle2 application failure. This is a regression from pre-bundle2 because the exit code changed. Because we no longer raise an Abort with the remote's message, we needed to insert a message for the new Abort. So, I invented a new error message for that. This is another change from pre-bundle2. However, I like the new error message because it states unambiguously who aborted the push failed, which I think is important for users so they can decide what's next.

tests: add tests for remote hook output (issue4788) The added tests don't agree in their output. This demonstrates a difference in `hg push` behavior between pre-bundle2 and bundle2. A subsequent patch will attempt to restore some of the pre-bundle2 behavior to bundle2.

debugrevlog: cope with empty revlog files I have no idea where it came from, but my clone of Mercurial has an empty filelog for `contrib/hgfixes/__init__.py` - it's *valid*, just contains no nodes. Without this change, debugrevlog crashes with a zero division error.

largefiles: don't mute and obfuscate http errors when putlfile fails 'unexpected putlfile response: None' when an http error occurs is not very helpful. Instead, leave the handling of urllib2.HTTPError exceptions to other layers.

largefiles: test coverage of error handling from putlfile This reveals a wrong and unhelpful 'unexpected putlfile response'.

largefiles: check hash of files in the store before copying to working dir If the store somehow got corrupted, users could end up in weird situations that were very hard to recover from or lead to propagation of the corruption. Instead, spend the extra time checking the hash when copying to the working directory. If it doesn't match, emit a warning, and don't put wrong content in the working directory.

largefiles: test coverage of handling of store corruption This reveals that update might put a corrupted largefile in the working directory where it will show up as modified and ready for commit.

merge: improve clarity of table in update docstring

ui: support paths.default-push without paths.default set (issue4914) This behavior regressed as part of the paths API refactoring. Previous behavior was to accept "default-push" without "default" defined. Current behavior aborts with "default repository not configured!." This patch restores the old behavior and adds test coverage for the scenario, which was absent before.

bookmarks: don't allow pushing new head for existing mark with -B (issue4400)

commands: fix help for debugobsolete

largefiles: fix explicit commit of normal/largefile switch Commit of corresponding normal/largefiles pairs would only commit the standin. That is usually fine, except if either the normal file or the standin is a remove while the other is an add. In that case it would either give duplicate colliding entries or lose the file. Instead, commit both filenames if one of them is a remove.

largefiles: test coverage of explicit commit of normal/largefile switch This reveals that a switch from normal to largefile violates the normal largefile invariant and gives a manifest with both a normal and standin file in the repository, while a switch from largefile to normal gives nothing. Not good.

bundlerepo: properly extract compressed changegroup from bundle2 Before this bundle repository were unable to work with compressed bundle2. We use the same approach as with bundle1, we extract the changegroup in uncompressed form into a temporary file.

bundle2: make unbundle.compressed return True when compressed We were returning 'False' in all cases, even when the bundle2 was actually compressed.

bundlerepo: uncompress changegroup in bundle1 case only Uncompressing bundle2 needs to be handled differently.

bundlerepo: move temp-bundle writing logic into a closure We will reuse this logic for bundle2

shelve: properly process bundle2 bundle

histedit: properly apply bundle2 backups If the histedit fails, we restore a backup. We make sure this backup bundle can be in bundle2 format as general delta will require.

strip: pass source and url to bundle2 processing Restoring from a 'bundle2' was missing this data.

unbundle: use 'url' argument with applybundle This will let the hook get access to the 'url' value.

applybundle: take url as argument We allow specifying the url to carry it to hooks. This gets us closer to 'bundle1.apply(...)' and will allow us to remove regressions in multiple place where we forget to pass the url to hooks.

unbundle: use 'source' argument with applybundle This will let the hook get access to the 'source' value.

applybundle: take source as argument We allow specifying the source to carry it to hooks. This gets us closer to 'bundle1.apply(...)' and will allow us to remove regressions in multiple places where we forget to pass the source to hooks.

applybundle: set 'bundle2=1' env for all transaction This should be set for all bundle2 application, we enforce that at a low level. This is for courtesy with hooks.

unbundle: use 'bundle2.applybundle' This is one such place.

bundle2: introduce an "applybundle" function There is a case where the intent is clear and the transaction is not optional. We want to be able to alter that transaction in a wide and easy way. We cannot get a unified '.apply(repo)' method for bundle1 and bundle2 yet because the api are still a bit too far apart. But this is a good step forward to get the rc out.

commands.resolve: conclude merge driver if no unresolved files are left This can happen when either 'hg resolve --all' is called or a driver-resolved file is explicitly requested. This is done as part of 'hg resolve --all' so that users still have a chance to test their changes before committing them. The exact semantics here are still to be decided. This does not impact any non-experimental features. Thanks to Pierre-Yves David for some advice about this behavior in particular, and merge drivers in general.

commands.resolve: call driverpreprocess if we haven't run it yet We need to be careful about allowing --mark and --unmark to keep working -- we don't want the user to be stuck in a weird state. The exact behavior here is still to be decided, though.

merge.applyupdates: call driverconclude after performing merge actions This will be a chance for the merge driver to finish resolving or generating any driver-resolved files. As before, having a separate error state from 'unresolved' is too big a refactoring for now, so we hack around it by setting unresolved to a positive value when necessary.

merge.applyupdates: call driverpreprocess before starting merge actions We also need to update our internal state to whatever state driverpreprocess leaves it in. Adding an error state separate from the unresolved count is too big a refactoring for now, so we hack around it by setting it to a positive value to indicate an error state.

merge: add stubs for preprocess and conclude steps of merge driver The exact semantics for what should happen (particularly with respect to error handling) are still a bit hard to pin down, so I think it's better to experiment with it as an extension for now. For now this stub will act as a convenient point for extensions to hook on.

commands.resolve: don't allow users to mark or unmark driver-resolved files Users will often be in the habit of running 'hg resolve --mark --all' after resolving merge conflicts in source files. We need to make sure this doesn't cause driver-resolved files to be marked. 'hg resolve --all' will resolve driver-resolved files, though. The weird conditional structure is to accommodate an upcoming patch.

merge.mergestate: set merge driver state to 's' if there's none present This allows mergestate.mdstate() to return 's' if there's nothing to be done on the merge driver end.

merge.mergestate: only check for merge driver when property is accessed Otherwise 'hg update --clean', 'hg rebase --abort' etc wouldn't work.

localrepo.commit: abort if merge driver's conclude step hasn't been run yet This case also requires 'hg resolve --all' to be run before continuing.

merge.mergestate: add a way to get the merge driver state This will be useful to check what the status of the merge driver is.

merge.mergestate: add a way to get the other side of the merge It's surprising there was no API at all for this until now. In any case this will be needed from custom merge drivers.

commands.resolve: support printing out driver-resolved files There's no user-visible way to mark files as driver-resolved, so this status won't be visible.

histedit: make histedit prune when obsolete is enabled Back in June we made histedit use obsolete markers to cleanup when possible. This was rolled back as part of 54f9561088c7 (which should have only rolled back the --abort stuff, but rolled back everything). This caused a nasty bug when used in conjuction with the inhibit+directaccess extensions where histedit would leave old nodes around even after they had been squashed away. The root of the problem is that we first clean up old nodes, and then we clean up temp nodes. In the first pass, when we obsoleted old nodes, some would become unobsolete because they had temp nodes on top of them, thus making them stick around even after the histedit finished. The fix is to A) move the temp node cleanup to be before the old node cleanup (since they are topological on top of the old nodes), and B) use obsolete markers instead of stripping.

clonebundles: rewrite documentation There are a lot of considerations server operators need to know before deploying clone bundles. They should be documented. So I rewrote the extension docs to contain this information.

exchange: support streaming clone bundles in clone bundles Now that we have support for detecting compatible stream clone bundles in bundle specifications, we can safely add support for applying stream clone bundles to the clone bundles feature.

exchange: parse requirements from stream clone specification string Stream clone bundles can only be consumed if the consumer supports the exact format requirements that were present on the producer. This patch adds support for encoding and verifying the format requirements on the bundle specification string for a stream clone bundle are supported by the local repository. If they aren't, we raise an UnsupportedBundleSpecification, just like we do when an unknown compression or bundle type is encountered. The impetus for this patch is so the clone bundles manifest can advertise stream clone bundles and so clients can filter out stream clones with unsupported format requirements. e.g. a stream clone produced with the not-yet-invented "revlogv2" format will be ignored by clients that only support "revlogv1."

exchange: support parameters in bundle specification strings Sometimes a basic type string is not sufficient for representing the contents of a bundle. Take bundle2 for example: future bundle2 files may contain parts that today's bundle2 parser can't read. Another example is stream clone data. These require clients to support specific repository formats or they won't be able to read the written files. In both scenarios, we need to describe additional metadata beyond the outer container type. Furthermore, this metadata behaves more like an unordered set, so an order-based declaration format (such as static strings) is not sufficient. We introduce support for "parameters" into the bundle specification string. These are essentially key-value pairs that can be used to encode additional metadata about the bundle. Semicolons are used as the delimiter partially to increase similarity to MIME parameter values (see RFC 2231) and because they are relatively safe from the command line (although values will need quotes to avoid interpretation as multiple shell commands). Alternatives considered were spaces (a bit annoying to encode) and '&' (similar to URL query strings) (which will do bad things in a shell if unquoted). The parsing function now returns a dict of parsed parameters and consumers have been updated accordingly.

commands: support consuming stream clone bundles For the same reasons that we don't produce stream clone bundles with `hg bundle`, we don't support consuming stream clone bundles with `hg unbundle`. We introduce a complementary debug command for applying stream clone bundles. This command is mostly to facilitate testing. Although it may be used to manually apply stream clone bundles until a more formal mechanism is (possibly) adopted.

commands: support creating stream clone bundles Now that we have support for recognizing the streaming clone bundle type, add a debug command for creating them. I decided to create a new debug command instead of adding support to `hg bundle` because stream clone bundles are not exactly used the same way as normal bundle files and I don't want to commit to supporting them through the official `hg bundle` command forever. A debug command, however, can be changed without as much concern for backwards compatibility. As part of this, `hg bundle` will explicitly reject requests to produce stream bundles. This command will be required by server operators using stream clone bundles with the clone bundles feature.

exchange: support for streaming clone bundles Now that we have a mechanism to produce and consume streaming clone bundles, we need to teach the human-facing bundle specification parser and the internal bundle file header reading code to be aware of this new format. This patch does so. For the human-facing bundle specification, we choose the name "packed" to describe "streaming clone bundles" because the bundle is essentially a "pack" of raw revlog files that are "packed" together. There should probably be a bikeshed over the name, especially since it is human facing.

streamclone: support for producing and consuming stream clone bundles Up to this point, stream clones only existed as a dynamically generated data format produced and consumed during streaming clones. In order to support this efficient cloning format with the clone bundles feature, we need a more formal, on disk representation of the streaming clone data. This patch introduces a new "bundle" type for streaming clones. Unlike existing bundles, it does not contain changegroup data. It does, however, share the same concepts like the 4 byte header which identifies the type of data that follows and the 2 byte abbreviation for compression types (of which only "UN" is currently supported). The new bundle format is essentially the existing stream clone version 1 data format with some headers at the beginning. Content negotiation at stream clone request time checked for repository format/requirements compatibility before initiating a stream clone. We can't do active content negotiation when using clone bundles. So, we put this set of requirements inside the payload so consumers have a built-in mechanism for checking compatibility before reading and applying lots of data. Of course, we will also advertise this requirements set in clone bundles. But that's for another patch. We currently don't have a mechanism to produce and consume this new bundle format. This will be implemented in upcoming patches. It's worth noting that if a legacy client attempts to `hg unbundle` a stream clone bundle (with the "HGS1" header), it will abort with: "unknown bundle version S1," which seems appropriate.

spelling: fix typo in transaction error messages

transaction: reorder unlinking .hg/journal and .hg/journal.backupfiles After this reordering, absence of '.hg/journal' just before starting new transaction means also absence of '.hg/journal.backupfiles'. In this case, all temporary files for preceding transaction should be completely unlinked, and HG_PENDING doesn't cause unintentional reading stalled temporary files in. Otherwise, 'repo.transaction()' raises exception with "run 'hg recover' to clean up transaction" hint.

merge: make in-memory changes visible to external update hooks 51844b8b5017 (while 3.4 code-freeze) made all 'update' hooks run after releasing wlock for visibility of in-memory dirstate changes. But this breaks paired invocation of 'preupdate' and 'update' hooks. For example, 'hg backout --merge' for TARGET revision, which isn't parent of CURRENT, consists of steps below: 1. update from CURRENT to TARGET 2. commit BACKOUT revision, which backs TARGET out 3. update from BACKOUT to CURRENT 4. merge TARGET into CURRENT Then, we expects hooks to run in the order below: - 'preupdate' on CURRENT for (1) - 'update' on TARGET for (1) - 'preupdate' on BACKOUT for (3) - 'update' on CURRENT for (3) - 'preupdate' on TARGET for (4) - 'update' on CURRENT/TARGET for (4) But hooks actually run in the order below: - 'preupdate' on CURRENT for (1) - 'preupdate' on BACKOUT for (3) - 'preupdate' on TARGET for (4) - 'update' on TARGET for (1), but actually on CURRENT/TARGET - 'update' on CURRENT for (3), but actually on CURRENT/TARGET - 'update' on CURRENT for (4), but actually on CURRENT/TARGET Root cause of the issue focused by 51844b8b5017 is that external 'update' hook process can't view in-memory changes (especially, of dirstate), because they aren't written out until the end of transaction (or wlock). Now, hooks can be invoked just after updating, because previous patches made in-memory changes visible to external process. This patch may break backward compatibility from the point of view of "scheduling hook execution", but should be reasonable because 'update' hooks had been executed in this order before 3.4. This patch tests "hg backout" and "hg unshelve", because the former activates the transaction before 'update' hook invocation, but the former doesn't.

hook: centralize passing HG_PENDING to external hook process This patch centralizes passing HG_PENDING to external hook process into '_exthook()'. To make in-memory changes visible to external hook process, this patch does: - write (or schedule to write) in-memory dirstate changes, and - set HG_PENDING environment variable, if: - a transaction is running, and - there are in-memory changes to be visible This patch tests some commands with some hooks, because transaction activity of a same hook differs from each other ("---": "not tested"). ======== ========= ========= ============ command preupdate precommit pretxncommit ======== ========= ========= ============ unshelve o --- --- backout x --- --- import --- o o qrefresh --- x o ======== ========= ========= ============ Each hooks are examined separately to prevent in-memory changes from being visible to external process accidentally by side effect of hooks previously invoked.

cmdutil: make in-memory changes visible to external editor (issue4378) Before this patch, external editor process for the commit log can't view some in-memory changes (especially, of dirstate), because they aren't written out until the end of transaction (or wlock). This causes unexpected output of Mercurial commands spawned from that editor process. To make in-memory changes visible to external editor process, this patch does: - write (or schedule to write) in-memory dirstate changes, and - set HG_PENDING environment variable, if: - a transaction is running, and - there are in-memory changes to be visible "hg diff" spawned from external editor process for "hg qrefresh" shows: - "changes newly imported into the topmost" before 49148d7868df(*) - "all changes recorded in the topmost by refreshing" after this patch (*) 49148d7868df changed steps invoking editor process Even though backward compatibility may be broken, the latter behavior looks reasonable, because "hg diff" spawned from the editor process consistently shows "what changes new revision records" regardless of invocation context. In fact, issue4378 itself should be resolved by 800e090e9c64, which made 'repo.transaction()' write in-memory dirstate changes out explicitly before starting transaction. It also made "hg qrefresh" imply 'dirstate.write()' before external editor invocation in call chain below. - mq.queue.refresh - strip.strip - repair.strip - localrepository.transaction - dirstate.write - localrepository.commit - invoke external editor Though, this patch has '(issue4378)' in own summary line to indicate that issues like issue4378 should be fixed by this. BTW, this patch adds '-m' option to a 'hg ci --amend' execution in 'test-commit-amend.t', to avoid invoking external editor process. In this case, "unsure" states may be changed to "clean" according to timestamp or so on. These changes should be written into pending file, if external editor invocation is required, Then, writing dirstate changes out breaks stability of test, because it shows "transaction abort!/rollback completed" occasionally. Aborting after editor process invocation while commands below may cause similar instability of tests, too (AFAIK, there is no more such one, at this revision) - commit --amend - without --message/--logfile - import - without --message/--logfile, - without --no-commit, - without --bypass, - one of below, and - patch has no description text, or - with --edit - aborting at the 1st patch, which adds or removes file(s) - if it only changes existing files, status is checked only for changed files by 'scmutil.matchfiles()', and transition from "unsure" to "normal" in dirstate doesn't occur (= dirstate isn't changed, and written out) - aborting at the 2nd or later patch implies other pending changes (e.g. changelog), and always causes showing "transaction abort!/rollback completed"

dirstate: show develwarn for write() invocation without transaction This is used to detect 'dirstate.write()' invocation without the value gotten by 'repo.currenttransaction()' (mainly focused on 3rd party extensions).
