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
