help: fix typo commited -> committed

largefiles: don't mangle filesets when fixing up the log matcher The fileset-generated.t test previously failed with this: + hg: parse error: unknown identifier: .hglf/modified + (did you mean 'modified'?) + [255] Filesets will find the standins on their own, without any help. While that's useful for some things like modified(), clean(), etc., it is wrong for things like size(). Proper fileset support for largefiles is not trivial, but this was failing with just the extension enabled on a normal repo.

largefiles: don't crash when cloning to a remote repo The immediate crash was when checking for requirements immediately after this, but lfcommands.downloadlfiles() will also crash if --all-largefiles is specified. That has been in place since atleast 5884812686f7 (2.3-rc) without anyone noticing. I can't tell from the peer classes if there's a way to make the custom largefile functionality work in this case, but atleast it doesn't crash.

run-tests: don't error when glob matched line ends with backslash As part of writing another test, I triggered an array index error in glob match processing code by having a (glob) line end in a single backslash (which is the escape character). Adding a simple bounds check prevents the error in run-tests.py.

histedit: change state format to allow non-hash lines The existing state serialization format assumed the rule line consisted of an action and a hash. In our external extension that adds 'exec' this is not the case (there is no hash, just the shell command). So let's change the format to be more generic with just an action and a remainder, and the various commands can handle it as they wish. Flagged for stable since we want to get this format tweak in before the new format goes live in the release.

tests: fix portability issue with test-merge-tools Not sure how this ever worked.

test-rename-merge2: fix test failure on Windows Windows and OpenVMS use double quote for shell quoting, posix uses single quote. Since the other test lines added in 5668202cfaaf don't include the quotes, this was presumably an oversight.

test-add.t: fix output difference between Windows and OS X (issue4603)

tags: do not abort if failed to write lock file to save cache LockHeld wasn't enough to suppress error during acquiring lock. If .hg directory is read-only, LockUnavailable will be raised. $ chmod ugo-w .hg $ hg identify abort: could not lock working directory of ...: Permission denied

Added signature for changeset e89f909edffa

Added tag 3.4-rc for changeset e89f909edffa

merge default into stable for 3.4 freeze

tests: fix up whitespace complaint

tests: fix test-tags on vfat The unix conditional section wasn't cleaning up sufficiently.

tests: ignore sha512 flag in bundle2 for py2.4

bundle2-localpeer: properly propagate the server output on error (issue4594) In case of errors, output parts salvaged from the reply bundle need to be processed for outputting their content. This concludes our quest for fixing issue4594.

bundle2: add on more layer of exception catching in localrepo.unbundle We are going to add output related logic in this function. We do the indentation first to help next changeset readability. We need a new try except because we want to handle output on any exception, including PushRaced ones.

bundle2-wireproto: properly propagate the server output on error (issue4594) In case of errors, output parts salvaged from the reply bundle are re-injected into the bundle carrying the exception. We still need to fix the situation for non-wireprotocol push.

bundle2: refactor error bundle creation for the wireprotocol We want to add output information to the error bundle. Before doing this, we rework the code to have a single bundler creation and return statement. This will make the update with the output simpler as only one place will have to be touched.

bundle2: store the salvaged output on the exception object The re-handling of output is happening in some 'unbundle' callers. We have to transmit the output information to this place so we stick it on the exception. This is the third step in our quest for preserving the server output on error (issue4594). We want to be able to copy the output part from the aborted reply into the exception bundle.

bundle2: add a 'salvageoutput' method on bundle20 This method returns a copy of all 'output' parts added to the bundler. This is the second step in our quest for preserving the server output on error (issue4594). We want to be able to copy the output parts from the aborted reply into the exception bundle. The function will be used in a later patch.

bundle2: add a 'copy' method on parts This is the first step in our quest for preserving the server output on error (issue4594). We want to be able to copy the output parts from the aborted reply into the exception bundle. The function will be used in a later patch.

hooks: add a 'txnabort' hook This hook will be called whenever a transaction is aborted. This will make it easy for people to clean up temporary content they may have created during a transaction.

help: document the ''HG_TXNID'' environment variable during hooks We forgot to document the new "transaction ID" mechanism.

match: add a subclass for dirstate normalizing of the matched patterns This class is only needed on case insensitive filesystems, and only for wdir context matches. It allows the user to not match the case of the items in the filesystem- especially for naming directories, which dirstate doesn't handle[1]. Making dirstate handle mismatched directory cases is too expensive[2]. Since dirstate doesn't apply to committed csets, this is only created by overriding basectx.match() in workingctx, and only on icasefs. The default arguments have been dropped, because the ctx must be passed to the matcher in order to function. For operations that can apply to both wdir and some other context, this ends up normalizing the filename to the case as it exists in the filesystem, and using that case for the lookup in the other context. See the diff example in the test. Previously, given a directory with an inexact case: - add worked as expected - diff, forget and status would silently ignore the request - files would exit with 1 - commit, revert and remove would fail (even when the commands leading up to them worked): $ hg ci -m "AbCDef" capsdir1/capsdir abort: CapsDir1/CapsDir: no match under directory! $ hg revert -r '.^' capsdir1/capsdir capsdir1\capsdir: no such file in rev 64dae27060b7 $ hg remove capsdir1/capsdir not removing capsdir1\capsdir: no tracked files [1] Globs are normalized, so that the -I and -X don't need to be specified with a case match. Without that, the second last remove (with -X) removes the files, leaving nothing for the last remove. However, specifying the files as 'glob:**.Txt' does not work. Perhaps this requires 're.IGNORECASE'? There are only a handful of places that create matchers directly, instead of being routed through the context.match() method. Some may benefit from changing over to using ctx.match() as a factory function: revset.checkstatus() revset.contains() revset.filelog() revset._matchfiles() localrepository._loadfilter() ignore.ignore() fileset.subrepo() filemerge._picktool() overrides.addlargefiles() lfcommands.lfconvert() kwtemplate.__init__() eolfile.__init__() eolfile.checkrev() acl.buildmatch() Currently, a toplevel subrepo can be named with an inexact case. However, the path auditor gets in the way of naming _anything_ in the subrepo if the top level case doesn't match. That is trickier to handle, because there's the user provided case, the case in the filesystem, and the case stored in .hgsub. This can be fixed next cycle. --- a/tests/test-subrepo-deep-nested-change.t +++ b/tests/test-subrepo-deep-nested-change.t @@ -170,8 +170,15 @@ R sub1/sub2/test.txt $ hg update -Cq $ touch sub1/sub2/folder/bar +#if icasefs + $ hg addremove Sub1/sub2 + abort: path 'Sub1\sub2' is inside nested repo 'Sub1' + [255] + $ hg -q addremove sub1/sub2 +#else $ hg addremove sub1/sub2 adding sub1/sub2/folder/bar (glob) +#endif $ hg status -S A sub1/sub2/folder/bar ? foo/bar/abc The narrowmatcher class may need to be tweaked when that is fixed.

match: move _normalize() into the match class This will be overridden in an upcoming patch to also deal with dirstate normalization on case insensitive filesystems.

largefiles: always consider updatelfiles 'checked' parameter set mergeupdate already set the flag to update all. This will thus only change overriderevert and scmutilmarktouched ... where the flag effectually also were true. The test coverage thus shows no change. As the flag always is set, it is removed. This is mainly a change for keeping the code simple and consistent and correct, but it should also make it faster in many cases.

largefiles: for update -C, only update largefiles when necessary Before, a --clean update with largefiles would use the "optimization" that it didn't read hashes from standin files before and after the update. Instead of trusting the content of the standin files, it would rehash all the actual largefiles that lfdirstate reported clean and update the standins that didn't have the expected content. It could thus in some "impossible" situations automatically recover from some "largefile got out sync with its standin" issues (even there apparently still were weird corner cases where it could fail). This extra checking is similar to what core --clean intentionally do not do, and it made update --clean unbearable slow. Usually in core Mercurial, --clean will rely on the dirstate to find the files it should update. (It is thus intentionally possible (when trying to trick the system or if there should be bugs) to end up in situations where --clean not will restore the working directory content correctly.) Checking every file when we "know" it is ok is however not an option - that would be too slow. Instead, trust the content of the standin files. Use the same logic for --clean as for linear updates and trust the dirstate and that our "logic" will keep them in sync. It is much cheaper to just rehash the largefiles reported dirty by a status walk and read all standins than to hash largefiles. Most of the changes are just a change of indentation now when the different kinds of updates no longer are handled that differently. Standins for added files are however only written when doing a normal update, while deleted and removed files only will be updated for --clean updates.

subrepo: calculate _relpath for hgsubrepo based on self instead of parent Prior to 105758d1b37b, the subrelpath() (now _relpath) for hgsubrepo was calculated by removing the root path of the outermost repo from the root path of the subrepo. Since the root paths use platform specific separators, and the relative path is printed by various commands, the output of these commands require a glob (and check-code.py enforces this). In an effort to be generic to all subrepos, 105758d1b37b started calculating this path based on the parent repo, and then joining the subrepo path in .hgsub. One of the tests in test-subrepo.t creates a subrepo inside a directory, so the path being joined contained '/' instead of '\'. This made the test fail with a '~' status, because the glob is unnecessary[1]. Removing them made the test work, but then check-code complains. We can't just drop the check-code rule, because sub-subrepos are still joined with '\'. Presumably the other subrepo types have this issue as well, but there likely isn't a test with git or svn repos inside a subdirectory. This simply restores the exact _relpath value (and output) for hgsubrepos prior to 105758d1b37b. [1] http://www.selenic.com/pipermail/mercurial-devel/2015-April/068720.html

subrepo: backout 93b0e0db7929 to restore reporelpath() The path for hgsubrepo needs to be calculated slightly differently from other subrepo types, but can reuse this. See the next patch for details.

rollback: clear resolve state (issue4593)

diff: pass the diff matcher to the copy logic This passes the existing diff matcher instance down to the copy logic so copy tracing can be more efficient when possible and only trace copies for matching files. This only actually affects forwardcopies (i.e. Given A<-B<-C<-D, it works for 'hg diff -r B -r D foo.txt', but not for 'hg diff -r D -r B foo.txt') since backward copies require walking all histories, and not just the individual file's. This reduces 'hg diff -r A -r B foo.txt' time from 15s to 1s when A and B have 80,000 files different.

copies: add matcher parameter to copy logic This allows passing a matcher down the pathcopies() stack to _forwardcopies(). This will let us add logic in a later patch to avoid tracing copies when not necessary (like when doing hg diff -r 1 -r 2 foo.txt).

treemanifest: extract parse method from constructor When we start to lazily load submanifests, it will be useful to be able to create an treemanifest instance before manifest data gets parsed into it. To prepare for this, extract the parsing code from treemanifest's constructor to a separate method.

manifest: duplicate call to addrevision() When we start writing submanifests to their own revlogs, we will not want to write a new revision for a directory if there were no changes to it. To prepare for this, duplicate the call to addrevision() and move them earlier where they can more easily be avoided.

record: add message when starting record's curses interface We are adding this log message to reduce a confusion when a command prints something just before starting the curses interface. Since the interactive mode is taking over the entire screen, starts with no delay and does wait for a key press, the user believes that messages printed before opening the interactive mode were actually printed after using interactive mode, not before. The fix adds the line "Starting interactive mode" helping the user separate the messages that were printed before and after the start of the interactive mode. One particular example where this was a problem is the revert command where we first print the list of changes to be considered for revert, then opens the curses interface right away without letting the user see the messages. The user then selects the changes, validates and then see the messages from before opening the interactive mode and is confused.

subrepo: add include/exclude support for diffing git subrepos Previously, git subrepos were ignored if any type of path selection was done. This can be solved by using subrepo status and filtering matching files.

revset: undocument wdir() until its command outputs get stable wdir() implementation is still incomplete and shouldn't be advertised to users. This patch will be backed out when - template values such as {rev} and {node} are settled - major commands and revsets work without crashing

linkrev: fix issue with annotate of working copy The introrev was appearing as None in new annotate tests, which the code from the stable branch wasn't expecting.

merge with stable

histedit: delete all non-actionclass related code Now that all actions have been migrated to the class format, we can delete all the unnecessary code that supported the old function format.

histedit: improve roll action integration with fold Previously the fold action would inspect it's class to figure out if it was a rollup or not. This was hacky. Now that finishfold is inside the fold class, let's modify it to check a function (which roll can override) to determine if it should be prompting for a commit message.

histedit: move finishfold into fold class Let's move the finishfold function into the fold class so we can modify it from the roll class more easily.

histedit: convert fold/roll actions into a class This converts the fold/roll actions into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness. The tests changed for two reasons: 1) We get a new 'empty changeset' warning because we now warn more consistently between normal histedit and --continue about commits disappearing. 2) Previously we were not putting the histedit-source extra field on the temporary fold commit during normal runs, but we were on --continue runs. By unifying these code paths we now consistently put histedit-source on the temporary fold commit, which changes some of the hashes in the backup bundles.

histedit: convert edit action into a class This converts the edit action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert message action into a class This converts the message action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert drop action into a class This converts the drop action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness.

histedit: convert pick action into a class This converts the pick action into a histeditclass instance, as part of an ongoing effort to refactor histedit for maintainability and robustness. The test output changed because previously pick would only report the commit disappearing if there were no merge conflicts. Now that we've unified the normal and the --continue flows, they act the same and we get the warning even after --continue.
