localrepo: use path expansion API via vfs As a part of migration to vfs, this patch moves path expansion API invocations in the constructor of "localrepository" to the constructor of "opener", because the root path to the repository is very important to handle paths using non-ASCII characters correctly. This patch also rearrange initialization order of "wvfs" field, because it is required to initialize "self.root".

localrepo: add "vfs" fields to "localrepository" for migration from "opener" As a part of migration to vfs, this patch adds "vfs" fields to "localrepository" class. This allows new codes to access current "opener" objects related to repositories via "vfs" fields, so patches referring to "vfs" will replace referring to "opener" in time. This patch also adds initializations for "vfs" fields to "statichttprepository" class derived from it, because its constructor doesn't invoke the constructor of "localrepository", so "vfs" fields should be initialized explicitly as same as "opener" fields: it has no working directory, so "wvfs" field is not added.

largefiles: optimize status by synchronizing lfdirstate with the largefile on update This speeds up status on a largefiles repo by synchronizing the largefiles dirstate to the largefile's mtime upon update, preventing the files from coming back as "unsure" later, requiring a check of the SHA1 sum.

store: abstract out how we retrieve a file's size

mq: check subrepo synchronizations against parent of workdir or other appropriate context Before this patch, MQ checks each subrepo synchronizations against the working directory context, so ".hgsubstate" updating is not imported into MQ revision correctly in cases below: - qrefresh when current ".hgsubstate" is already synchronized with each subrepos: you can reproduce this easily by just twice or more qrefresh invocations - qnew just after rollback of commit which updates ".hgsubstate" This patch resolves this by checking subrepo states against: - the parent of "qtop" for qrefresh, or - the parent of working context otherwise

mq: create patch file after commit to import diff of ".hgsubstate" at qrefresh Even though the committed revision contains diff of ".hgsubstate", the patch file created by qrefresh doesn't contain it, because: - ".hgsubstate" is not listed up as one of target files of the patch for reasons below, so diff of ".hgsubstate" is not imported into patch file - status of ".hgsubstate" in working directory is usually "clean" - ".hgsubstate" is not specified explicitly by users - the patch file is created before commit processing which updates or creates ".hgsubstate" automatically, so there is no diff for it at that time This patch resolves this problem by: - putting ".hgsubstate" into target list of the patch, if needed: this allows "patch.diff()" to import diff of ".hgsubstate" into patch file. - creating the patch file after commit processing: this updates ".hgsubstate" before "patch.diff()" invocation. For the former fixing, this patch introduces "putsubstate2changes()" to share same implementation with qnew. This is invoked only once per qnew/qrefresh at most, so there is less performance impact. This patch also omits "match" argument for "patch.diff()" invocation, because "patch.diff()" ignores "match" if "changes" is specified.

mq: add ".hgsubstate" to patch target list only if it is not listed up yet If ".hgsubstate" is already listed up as one of commit targets, qnew put diff of ".hgsubstate" twice into the patch file stored under ".hg/patches". It causes rejections at applying such patches. Other than the case like in added test script, this can also occur when qnew is executed just after rolling back the committing updated ".hgsubstate". This patch checks whether ".hgsubstate" is already listed up as one of commit targets, and put it into the appropriate list only if it is not listed up yet.

revert: use term "uncommitted merge" in help text to make sure users can't possibly be mislead to try this for canceling a *merge changeset*.

histedit: use cmdutil.command decorator

hgweb: show help with verbose sections included This makes sure we see the same help info as with 'hg help <command> --verbose' on the command line, that is, with verbose sections included.

update: mention how update can be used to cancel an uncommitted merge

update: move help text about parent revision higher up emphasizing how important the parent revision is

rollback: move examples and --force note in help into verbose section Plain 'hg help rollback' now looks like this: $ hg help rollback hg rollback roll back the last transaction (dangerous) This command should be used with care. There is only one level of rollback, and there is no way to undo a rollback. It will also restore the dirstate at the time of the last transaction, losing any dirstate changes since that time. This command does not alter the working directory. Transactions are used to encapsulate the effects of all commands that create new changesets or propagate existing changesets into a repository. This command is not intended for use on public repositories. Once changes are visible for pull by other users, rolling a transaction back locally is ineffective (someone else may already have pulled the changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull from the repository may fail if a rollback is performed. Returns 0 on success, 1 if no rollback data is available. options: -n --dry-run do not perform actions, just print output -f --force ignore safety measures --mq operate on patch repository use "hg -v help rollback" to show more info

revlog: fix for generaldelta distance calculation The decision whether or not to store a full snapshot instead of a delta is done based on the distance value calculated in _addrevision.builddelta(rev). This calculation traditionally used the fact of deltas only using the previous revision as base. Generaldelta mechanism is changing this, yet the calculation still assumes that current-offset minus chainbase-offset equals chain-length. This appears to be wrong. This patch corrects the calculation by means of using the chainlength function if Generaldelta is used.
