localrepo: drop dead comment

record: re-enable whitespace-ignoring options It looks like somewhere down the line, patch.diffopts changed the names of the options that it recognises, but record.recordfunc wasn't updated to the new names. Instead of trying to write down names at all, we now use whatever names are provided in commands.diffwsopts and pass that along to patch.diffopts, along with a couple of custom options

record: use commands.diffwsopts instead of ad-hoc diffopts The record extension is writing its own version of commands.diffwsopts which is identical to commands.diffwsopts. Based on the principle that code duplication increases maintenance burden, this patch removes record's ad-hoc diffopts in favour of commands.diffwsopts

phases: add a formal note that hash of secret changeset may leak out For technical reason (discovery, obsolescence marker) the hash of secret changeset are communicated outside of your repo. We clarifie that in the help so that people does not used hash of secret changeset as nuclear launch code.

largefiles: stylistic cleanup of filemerge

largefiles: show hashes before prompting for conflict resolution The largefile hashes are mostly an implementation detail, but they are "leaked" in several places anyway, and showing the hashes is better than not giving the user any information about the options in the prompt. The hashes are long, but it is largefile hashes and it would thus be confusing to shorten them.

largefiles: don't try to explain rename history before prompt for conflicts Before it tried to explain the exact situation when merging moved largefiles. That do not happen for normal merges and is not more relevant for largefiles than for normal files. It is unneeded complexity - remove it.

largefiles: drop redundant special handling of merges of renames It is unclear what cases this was supposed to cover but it do no longer seem relevant.

diff: search beyond ancestor when detecting renames This removes an optimization that was introduced in 91eb4512edd0 but was too aggressive - as indicated by how it changed test-mq-merge.t . We are walking filelogs to find copy sources and we can thus not be sure to hit the base revision and find the renamed file there - it could also be in the first ancestor of the base ... in the filelog. We are walking the filelog and can thus not easily know when we hit the first ancestor of the base revision and which filename to look for there. Instead, we use _findlimit like mergecopies do: The lower bound for how far we have to go is found from the lowest changelog revision that is an ancestor of only one of the compared revisions. Any filelog ancestor with a revision number lower than that revision will be the ancestor of both compared revisions, and there is thus no reason to go further back than that.

cat: increase perf when catting single files Special case the single file case in hg cat. This allows us to avoid parsing the manifest, which shaves 15% off hg cat perf. This is worth it, since automation often uses hg cat for retrieving single files.

changectx: increase perf of walk function When running 'hg cat -r . <file>' it was doing an expensive ctx.walk(m) which applied the regex to every file in the manifest. This changes changectx.walk to iterate over just the files in the regex, if no other patterns are specified. This cuts hg cat time by 50% in our repo and probably benefits a few other commands as well.

url: added authuri when login information is requested (issue3209) When users are using a revset they can get multiple password prompts. This prompts have no extra information about which password is being requested so I added the authuri to the prompt to make it recognizable. As in: $ hg log -r "outgoing('https://bitbucket.org/mg/test') - outgoing('https://bitbucket.org/nesneros/test')" http authorization required realm: Bitbucket.org HTTP user: interrupted! I changed it to describe the url when prompting for password. As in: $ hg log -r "outgoing('https://bitbucket.org/mg/test') - outgoing('https://bitbucket.org/nesneros/test')" http authorization required for https://bitbucket.org/mg/test realm: Bitbucket.org HTTP user: interrupted!

doc: add description about pattern matching against directories Before this patch, there is no explicit description about pattern matching against directories, even though users may understand it from "plain examples" in "hg help patterns". This patch adds description about pattern matching against directories.

revset: add explanation about the pattern without explicit kind Before this patch, online help of "adds()", "contains()", "filelog()", "file()", "modifies()" and "removes()" predicates doesn't explain about how the pattern without explicit kind like "glob:" is treated, even though each predicates treat it differently: - as "relpath:" by "adds()", "modifies()" and "removes()" - as "glob:" by "file()" - as special by "contains()" and "filelog()" - be relative to cwd, and - match against a file exactly ("relpath:" matches also against a directory) This may confuse users. This patch adds explanation about the pattern without explicit kind to these predicates.

revset: use "canonpath()" for "filelog()" pattern without explicit kind Before this patch, revset predicate "filelog()" uses "match.files()" to get filename also for the pattern without explicit kind. But in such case, only canonicalization of relative path is required, and other initializations of "match" object including regexp compilation are meaningless. This patch uses "pathutil.canonpath()" directly for "filelog()" pattern without explicit kind like "glob:", for efficiency. This patch also does below as a part of introducing "canonpath()": - move location of "matchmod.match()" invocation, because "m" is no more used in "if not matchmod.patkind(pat)" code path - omit passing "default" argument to "matchmod.match()", because "pat" should have explicit kind of pattern in this code path

revset: avoid loop for "match.files()" having always one element for efficiency This patch avoids the loop for "match.files()" having always one element in revset predicate "filelog()" for efficiency: "match" object "m" is constructed with "[pat]" as "patterns" argument.

revset: make default kind of pattern for "contains()" rooted at cwd Before this patch, default kind of pattern for revset predicate "contains()" is treated as the exact file path rooted at the root of the repository. This decreases usability, because: - all other predicates taking pattern argument (also "filelog()") treat such pattern as the path rooted at the current working directory - "contains()" doesn't describe this difference in its help - this difference may confuse users for example, this prevents revset aliases from sharing same argument between "contains()" and other predicates This patch makes default kind of pattern for revset predicate "contains()" be rooted at the current working directory. This patch uses "pathutil.canonpath()" instead of creating "match" object for efficiency.

revset: narrow scope of the variable referred only in specific code path This patch narrows scope of the variable "m" in the function for revset predicate "contains()", because it is referred only in "else" code path of "if not matchmod.patkind(pat)" examination.

tests: fix test-run-tests.py on OS X Do the same hack as in test-doctests.py to let the test pass on OS X.

tests: test-debugcommands.t also matches stack trace on python 2.4 Some versions of python 2.4 write ? instead of <module>. Ignore this detail by a glob. This fixes a failure spotted on buildbot, existing since this test lines were introduced 47d0843647d1.

commands: use bookmarks.validdest instead of duplicating logic Now that bookmarks.py has grown a validdest method that even handles successor changesets, we use that instead of duplicating the logic in commands.py

update: consider successor changesets when moving active bookmark Previously, when an obsolete changeset was bookmarked, successor changesets were not considered when moving the bookmark forward. Now that a bare update will move to the tip most of the successor changesets, we also update the bookmark logic to allow the bookmark to move with this update. Tests have been updated and keep issue4015 covered as well.

merge: consider successor changesets for a bare update Previously, a bare update would ignore any successor changesets thus potentially leaving you on an obsolete head. This happens commonly when there is an old bookmark that hasn't been moved forward which is the motivating reason for this patch series. Now, we will check for successor changesets if two conditions hold: 1) we are doing a bare update 2) *and* we are currently on an obsolete head. If we are in this situation, then we calculate the branchtip of the successor set and update to that changeset. Tests coverage has been added.

merge: refactor initialization of variables in update There is no code change here but this helps prepare for future commits that will fix a bare update with obsolete markers.
