rebase: use '>= 0' to know is a revision was rebased The fact that the state for "not yet rebased" is -1 is an implementation details. So we change the comparisons to some semantically more correct.

patchbomb: introduce a 'patchbomb.confirm' option When set to true, this option will make patchbomb always ask for confirmation before sending the email. Confirmation is a powerful way to prevent stupid mistakes when the sending patches. This should let me get rid of my global alias adding --confirm to hg email. I know that some people may get bitten when moving from a machine with confirm configured to a machine where it is not, but I think it is worth the risk.

patchbomb: add a 'patchbomb.intro' option This option allows the user to control the default behavior for including an introduction message. This avoids having to tirelessly skip the intro for people contributing to Mercurial. The three possibles values are: - always, - auto (default, current behavior), - never. I was thinking of ("true", "false", "") (empty value being auto) but I ruled it out as too confusing. This new config option reuses the pre-existing 'patchbomb' section.

patchbomb: extract 'getoutgoing' closure into its own function This continues my crusade against closure complication.

perf: add a perfloadmarkers command It is used to benchmark the obsstore initialization time.

rebase: move base calculation from rebasenode() to defineparents() We want to collect all calculation in one place.

largefiles: remove redundant checks for false modify/delete conflicts In a34a99181f36 (largefiles: don't show largefile/normal prompts if one side is unchanged, 2014-12-01), overridecalculateupdates() started checking for false modify/delete conflicts in large files and their standins. Then, in the very next changeset, 902554884335 (merge: before cd/dc prompt, check that changed side really changed, 2014-12-01), calculateupdates() itself started checking for false modify/delete conflicts in all files. Since "large files and their standins" is a subset of "all files", we can now drop the checks in overridecalculateupdates().

merge: make 'keep' message more descriptive Most merge action messages don't describe the action itself, they describe the reason the action was taken. The only exeption is the 'k' action, for which the message is just "keep" and instead there is a code comment folling it that says "remote unchanged". Let's move that comment into the merge action message.

addremove: restore the relative path printing when files are named This fixes the previously mentioned issue with 3778884197f0, and undoes its corresponding test change. The test change demonstrates the correctness when a file is specified (i.e. the glob is required on Windows because relative paths use '\' and absolute paths use '/'). It is admittedly very subtle, but there will be a more robust test in the addremove -S v3 series.

match: introduce uipath() to properly style a file path Several methods print files relative to the repo root, unless files are named on the command line, in which case they are printed relative to cwd. Since the check relies on the 'pats' parameter, which needs to be replaced by a matcher when adding subrepo support, this logic gets folded into the matcher to tidy up the callers. Prior to 3778884197f0, this style decision was based off of whether or not the 'pats' list was empty. That change altered the check to test match.anypats() instead, in order to make paths printed consistent when -I/-X is specified. That however, changed the style when a file is given to the command. So now we test the pattern list to get the old behavior for files, as well as test -I/-X to get the consistency for patterns.

merge with stable

update: don't overwrite untracked ignored files on update When looking for untracked files that would conflict with a tracked file in the target revision (or the remote side of a merge), we explcitly exclude ignored files. The code was added in 7e30f5f2285f (merge: refactor unknown file conflict checking, 2012-02-09), but it seems like only unknown, not ignored, files were considered since the beginning of time. Although ignored files are mostly build outputs and backup files, we should still not overwrite them. Fix by simply removing the explicit check.

update: add tests for untracked local file We don't seem to have any tests for updating to another revision when there are untracked files on the local side that conflict with the those on the remote side, so let's add tests. This shows how we overwrite untracked ignored files when updating to a revision that tracks the file.

merge: don't overwrite conflicting file in locally renamed directory When the local side has renamed a directory from a/ to b/ and added a file b/c in it, and the remote side has added a file a/c, we end up overwriting the local file b/c with the contents of remote file a/c. Add a check for this case and use the merge ('m') action in this case instead of the directory rename get ('dg') action.

merge: don't ignore conflicting file in remote renamed directory When the remote side has renamed a directory from a/ to b/ and added a file b/c in it, and the local side has added a file a/c, we end up moving a/c to b/c without considering the remote version of b/c. Add a check for this case and use the merge ('m') action in this case instead of the directory rename ('dm') action.

merge: duplicate 'if f in copied' into each branch

merge: branch code into {n1 and n2, n1, n2} top-level cases There are three high-level cases that are of interest in manifestmerge(): 1) The file exists on both sides, 2) The file exists only on the local side, and 3) The file exists only on the remote side. Let's make this clearer in the code. The 'if f in copied' case will be broken up into the two applicable branches in the next patch.

update: remove redundant and misplaced merge tests The "nothing to merge" case is covered by test-merge-default.t. The "uncommitted changes" case is covered by test-merge1.t (and others). The "merge -f" case is covered by test-merge-force.t.

largefiles: use clearer debug messages in actions In overridecalculateupdates(), 'g' (get) actions may be converted into other actions. In most of these cases, it does not make sense to keep the action's message. For example, 'remote created' does not make sense for an 'r' (remove) action.

largefiles: don't clobber merge action message with user message The message in the action is used for debugging and should not be the same as the question presented to the user. Use a different variable for the user message, so the 'msg' variable already in scope does not get overwritten.

bookmarks: factor out repository lookup from writing bookmarks file This will allow the share extension to extend bookmarks functionality to share bookmarks between repositories.

parsers: ensure revlog index node tree is initialized before insertion Currently, the revlog index C implementation assumes its node tree will be initialized before a new element is inserted by revnum. For example, revlog.py executes 'self.index.insert(-1, e)' in _addrevision(). This is only safe because the node tree has been initialized by a "node in self.nodemap" check made in addrevision(). (For context, this was discovered while developing an experimental revlog mixin which stores "elided nodes" via a separate code path from _addrevision(); that new code path segfaults without this patch.)

revset: add 'only' to DoS-safe symbols There is no reason to disable it in hgweb because the same query can be written without using 'only()'.

revset: move 'only' so that functions are sorted alphabetically

tests: drop unnecessary glob that causes a warning on Windows This was triggered by 3778884197f0.

merge: add test with conflicting file and remote directory rename Changset 88629daa727b (merge: demonstrate that directory renames can lose local file content, 2014-12-02) should clearly have added the reverse version of the test: where the remote side renamed a directory, added a new file in that directory, and the local directory added a conflicting file in the source directory. Add such a test now, and also touch up the ones already added slightly (e.g. 'local' was a stupid value for content that can be on either side of a merge).

graft: use a real conflict for the tests One of the graft tests grafts a changeset that changes a file's content from 'a' to 'b' onto a branch that has changed the file's content from 'a', via 'b', and then back to 'a' again. To prepare for not considering this a file in need of merging, let's use 'c' as the file's new content to make sure it has to be considered conflicting. There's a second similar case further down where an ancestor is grafted. Make sure that is also considered a conflict.

add: use lexists so that broken symbolic links are added This restores the add behavior prior to d8cdd46f426d and matches the behavior of addremove.

rebase: avoid redundant repo[rev].rev() - just keep working in rev space

rebase: always store rev in state, also when collapsing

rebase: clarify naming of variables holding node hashes - don't call them rev

bookmarks: factor out bookmark file opening for easier extensibility
