alias: provide "unknowncmd" flag to tell help to look for disabled command This patch prepares for breaking the call loop: help.help_() -> cmdalias() -> commands.help_() -> help.help_().

alias: keep error message in "badalias" so that help can see it Upcoming patches will - change help_() to get badalias message without executing cmdalias() - raise Abort on bad alias

alias: add test for alias command provided by disabled extension This should complete cases where "badalias" is set.

alias: expand "$@" as list of parameters quoted individually (BC) (issue4200) Before this patch, there was no way to pass in all the positional parameters as separate words down to another command. (1) $@ (without quotes) would expand to all the parameters separated by a space. This would work fine for arguments without spaces, but arguments with spaces in them would be split up by POSIX shells into separate words. (2) '$@' (in single quotes) would expand to all the parameters within a pair of single quotes. POSIX shells would then treat the entire list of arguments as one word. (3) "$@" (in double quotes) would expand similarly to (2). With this patch, we expand "$@" (in double quotes) as all positional parameters, quoted individually with util.shellquote, and separated by spaces. Under standard field-splitting conditions, POSIX shells will tokenize each argument into exactly one word. This is a backwards-incompatible change, but the old behavior was arguably a bug: Bourne-derived shells have expanded "$@" as a tokenized list of positional parameters for a very long time. I could find this behavior specified in IEEE Std 1003.1-2001, and this probably goes back to much further before that.

test-alias: add some tests to ensure we aren't double-substituting An earlier iteration of an upcoming patch caused inadvertent double substitution. Ensure we have test coverage for this.

revert: issue "no changes needed" message for files missing on both side When a file was marked as removed in the working copy and did not existed in the target of the revert, we did not issued any message pointing that no change was needed to the file (implicitly saying that revert had changed the file). We now properly issue a message in this situation. Tests change in and handful of case where the message was documented as missing.

revert: call status against revert target too We now call status against the target (and possibly against the working directory parent is different). We do not use the information from the two sources yet, but this is coming soon. We need the status information aganst the dirstate in all case because we need to be able to backup local modification.

revert: prefix variable names for dirstate status with "ds" As we are going to introduce status again other revision we needs to distinguish between data from dirstate status and the other one. We prefix the existing data with "ds" to highlight this.

revert: move manifest membership condition outside of the loop Currently, revset is using information from dirstate status and alter its behavior whenever the file exist in the target manifest or not. This tests are done a big for loop. We move this member ship testing outside of the loop and simplifies associates data structure. This is a step toward a cleaner implementation of revert based on status.

histedit: add "roll" command to fold commit data and drop message (issue4256) This new histedit command (short for "rollup") is a variant of "fold" akin to "hg amend" for working copy: it accumulates changes without interrupting the user and asking for an updated commit message.

repoview: cache hidden changesets Use the introduced caching infrastructure to cache hidden changesets. We crosscheck if the content of the cache unless experimental.verifyhiddencache is set to False. This will be removed in the future. Without crosschecking the caches speed ups hg status and other commands: without caching: $ time hg status hg status 0.72s user 0.20s system 100% cpu 0.917 total with caching $ time hg status hg status 0.49s user 0.15s system 100% cpu 0.645 total

repoview: add caching bits Add a caching infrastructure to cache hidden changesets. The cache tries to read the cache lazily and falls back to recomputing if no wlock can be obtain. To validate the cache we store a sha of the obstore content and repo heads in the beginning of the cache which we check every request.

repoview: split _gethiddenblockers Split up _gethiddenblockers into two categories: (1) "static' blockers that solely rely on the contents of obstore and are visible children of hidden changsets. (2) "dynamic" blockers, appearing by having wd parents, bookmarks or tags pointing to hidden changesets. We assume that (1) doesn't change often and can be easily cached with a good invalidation strategy. (2) change often, but barely produce blockers, so we can recompute them if necessary.

repoview: use set for blockers Blockers should be unique but tags and bookmarks could point to the same rev, therefore use a set to ensure that we don't have duplicates.

histedit: preserve initial author on fold (issue4296) When the authorship of the changeset folded in does not match that of the base changeset, we currently use the configured ui.username instead. This is especially surprising when the user is not the author of either of the changesets. In such cases, the resulting authorship (the user's) is clearly incorrect. Even when the user is folding in a patch they authored themselves, it's not clear whether they should take over the authorship. Let's instead keep it simple and always preserve the base changeset's authorship. This is also how "git rebase -i" handles folding/squashing.

test-revert: add case where file exists neither in "base" nor in "parent"

test-revert: add case where the file is removed between "base" and "parent"

test-revert: add case where file is unchanged between "base" and "parent" This test highlights a minor misbehavior in the message displayed during an explicit revert with a target revision.

test-revert: add methodical revert to "base" with explicit file path We now also test reverting file to another revision's content. However this differs from previously introduced test by using the explicit path of each "case file" when calling revert. This should result in the same result regarding file content and backup creation, but the output of the `hg revert` call should differ.

test-revert: add methodical revert with explicit file path We now also test reverting file to the working directory parent content. However this differs from the previously introduced test by using the explicit path of each "case file" when calling revert. This should result in the same result regarding file content and backup creation, but the output of the `hg revert` call should differ.

test-revert: add methodical revert to "base" We now also test reverting s file to the content of another revision. This is still done using the `--all` flag.

test-revert: add methodical revert to parent for working directory Now that we can automatically generate states, we need to actually run revert on them and check the result. While running such tests we are checking multiple elements. The output of the `hg revert` command, the resulting content of file, and the creation of backup file. The first practical test is using the simple case `hg revert --all`, reverting all files to working directory parent content.

test-revert: display the list of all generated cases This will help to track all existing cases. (still very simple now)

test-revert: also create a text version of the snapshot The text version is just a list of existing files with their content. We use a small custom script for that. This is going to be very useful for comparing revert results with revert target content.

hg-test-mode: make exit code highlight work again

test-revert: prepare methodical testing of revert cases We introduce a script to generate revert cases and use it to prepare a test repo. See the inline documentation for details.

test-revert: drop useless comments There are multiple comments explaining the expected output of commands. This is an old relic of the pre-unified test era. We remove them for uselessness.

run-tests: attempt to fix iolock handling Ideally, when using -j and -i together, when a prompt comes up, we'd like all other output to wait (but testing to continue!). This gets other output to wait by adding back a bunch of the locking that formerly existed. We switch to a recursive lock to deal with the restructuring due to unittest compatibility. Running tests continue to run, but now the scheduler doesn't schedule any new tasks while waiting at a prompt because no task slots become available due to result output happening in the thread and blocking on the iolock.

largefiles: synchronize lfdirstate with dirstate after automated committing Before this patch, after successful "hg rebase" of the revision removing largefiles, "hg status" may still show ""R" for such largefiles unexpectedly. "lfilesrepo.commit" executes the special code path for automated committing while rebase/transplant, and lfdirstate entries for removed files aren't updated in this code path, even after successful committing. Then, "R" entries still existing in lfdirstate cause unexpected "hg status" output. This patch synchronizes lfdirstate with dirstate after automated committing. This patch passes False as "normallookup" to "synclfdirstate", because modified files in "files()" of the recent (= just committed) context should be "normal"-ed. This is a temporary way to fix with less changes. For fundamental resolution of this kind of problems in the future, lfdirstate should be updated with dirstate simultaneously. Hooking "markcommitted" of ctx in "localrepository.commitctx" may achieve this. This problem occurs, only when (1) the parent of the working directory is rebased and (2) it removes largefiles, because: - if the parent of the working directory isn't rebased, returning to the initial revision (= update) after rebase hides this problem - files added on "other" branch (= rebase target) are treated not as "added" but as "modified" (= "normal" status and "unset" timestamp) at merging This patch tests also the status of added largefile, but it is only for avoiding regression. In addition to conditions above, "hg status" must not take existing files to reproduce this problem, because existing files make "match._files" not empty in "lfilesrepo.status" code path below: def sfindirstate(f): sf = lfutil.standin(f) dirstate = self.dirstate return sf in dirstate or sf in dirstate.dirs() match._files = [f for f in match._files if sfindirstate(f)] Not empty "match._files" prevents "status" on lfdirstate from returning the result containing problematic "R" files. This is reason why "large1" (removed) and "largeX" (added) are checked separately in this patch. Problematic code path in "lfilesrepo.commit" is used also by "hg transplant", but this problem doesn't occur at "hg transplant", because invocation of "updatelfiles" after transplant-ing in "overridetransplant" causes cleaning lfdirstate up. This patch tests also "hg transplant" as same as "hg rebase", but it is only for avoiding regression.

largefiles: drop orphan entries from lfdristat at "hg rollback" Before this patch, newly added (but not yet committed) largefiles aren't treated as unknown ("?") after "hg rollback". After "hg rollback", lfdirstate still contains "A" status entries for such largefiles, even though corresponding entries for standins are already dropped from dirstate. Such "orphan" entries in lfdirstate prevent unknown (large)files in the working directory from being listed up in "unknown" list. The code path in "if working" route of "lfilesrepo.status" below drops largefiles tracked in lfdirstate from "unknown" list: lfiles = set(lfdirstate._map) # Unknown files result[4] = set(result[4]).difference(lfiles) This patch drops orphan entries from lfdristate at "hg rollback". This is a temporary way to fix with less changes. For fundamental resolution of this kind of problems in the future, lfdirstate should be rollback-ed as a part of transaction, as same as dirstate.

largefiles: restore R status of removed largefiles correctly at "hg rollback" Before this patch, removed or forgotten largefiles aren't treated as removed ("R") after "hg rollback". Removed ones are treated as missing ("!") and forgotten ones are treated as clean ("C") unexpectedly. "overriderollback" uses "normallookup" to restore status in lfdirstate for largefiles other than ones not added in rollback-ed revision, but this isn't correct for removed (or forgotten) largefiles. This patch uses "lfutil.synclfdirstate" to restore "R" status of removed (or forgotten) largefiles correctly at "hg rollback". This is a temporary way to fix with less changes. For fundamental resolution of this kind of problems in the future, lfdirstate should be rollback-ed as a part of transaction, as same as dirstate.

largefiles: factor out synchronization of lfdirstate for future use

largefiles: put whole rollback-ing process into the same "wlock" scope Before this patch, there are three distinct "wlock" scopes in "overriderollback": 1. "localrepository.rollback" via original "rollback" command, 2. "merge.update" for reverting standin files only, and 3. "overriderollback" specific "wlock" scope (to synchronize largefile dirstate) But these should be executed in the same "wlock" scope for consistency.

hg-test-mode: colorize HGFOO and TESTFOO environment variables

unbundle: don't advance bookmarks (issue4322) (BC) This behavior didn't make much sense and interacts badly with things that use unbundle internally like shelve. Presumably, the original rationale was that since bundles didn't contain bookmarks, this gave a sense of keeping bookmarks up-to-date like would happen with a corresponding pull. However, since it only updated the current active bookmark, and bare update already did that anyway, this is pretty slim. Notably, the corresponding test actually works better without this feature.

contrib: add emacs mode for *.t files

phase: attach phase to the transaction instead of the lock The phase cache file is no longer written on lock release, it is now handled by the transaction (as changesets and obsolescence markers are). (Hooray) As we stop relying on the lock to write phase, repos with no existing phase information will need to wait for a phase move or a strip to happen in order to get the first write in the `phaseroots` file. This explain the change in test-inherit-mode.t. This should not have any side effects but in very obscure cases where people interact with pre-2.1 and post-2.1 versions of Mercurial on the same repo while having MQ patches applied but the MQ extension disabled from time to time. A case unlikely enough to not be worth preserving the old behavior with awful hacks.

phase: extract the phaseroots serialization in a dedicated method In most case, the file creation logic will be handled by the transaction itself. The write method has to stay around for the case where the repository is modified outside a transaction (strip).

transaction: add a file generation mechanism A new `transaction.addfilegenerator` function is added. It allows external code to register files to be generated. See inline documentation for details. It is important to gather all file creation logic on the transaction as at some point we'll want to mimic the "pre-transaction-commit" logic that we use for revlog. I'm refering to the logic that lets hooks see the result of the transaction before it actually gets committed.

transaction: backup file in a dedicated "namespace" File backup may conflict with other "journal.*" file. We add a fixed part in the backup name file to prevent it.

transaction: use `self.journal` to create backup file Transaction journal name is "journal" in most case, but it can be something else. We use the appropriate attribute to create the file.

We work around this by filtering the output of any 'hg email' invocations in the test that produce MIME messages.

phase: add a transaction argument to retractboundary We now pass a transaction option to this phase movement function. The object is currently not used by the function, but it will be in the future. All call sites have been updated. Most call sites were already enclosed in a transaction for a long time. The handful of others have been recently updated in previous commit.

phase: add a transaction argument to advanceboundary We now pass a transaction option to this phase movement function. The object is currently not used by the function, but it will be in the future. All call sites have been updated. Most call sites were already enclosed in a transaction for a long time. The handful of others have been recently updated in previous commit. The retractboundary function remains to be upgraded.

pull: pre-filter remote phases before moving local ones We were relying on the phase internals to filter out redundant phase information from remove. However as we plan to integrate phase movement inside the transaction, we want to avoid useless transaction creation on no-op pulls. Therefore we filter out all the information that already matches the current repository state. This will let us create a transaction only when there is actual phase movement needed.

test-check-commit-hg.t: automatically test all 'draft() and ::.' changesets We introduce a test-check-commit-hg.t file that will happily run the check-commit file on all draft changeset under the working directory. This should help newcomers to catch up with the rules. (And will helps old timer from time to time).

strip: remove -b/--backup codepaths cset ba3bc6474bbf has removed this option. This commit just tidies the code that was associated to it. It also fixes the internal calls to the strip() function. Before this change, any function that thought it would want as a final safety to keep a partial backup bundle (bundling changes not linearly related to the current change being stripped), had to explicitly pass a backup="strip" option. With this change, these backups are always kept in case of an exception and always removed if there is no exception. Only full backups can be specified with backup=True or no full backups with backup=False.
