dirstate.walk: remove subrepo and .hg from results before step 3 An upcoming patch will speed dirstate.walk up by not querying the results dict when it is empty. This ensures it is in some common cases. This should be safe because subrepos and .hg aren't part of the dirstate.

blackbox: account for another source of errors

hgk: remove regsub, split on \r instead No need to regsub all \r\n's to \n's, we can just split on \r as well; this may produce extra empty elements in the list, but they won't match anyway.

hgk: simplify tags parser As when hg tags is being called without -v option, it returns lines with two elements in each, we can just interate them as if it were a usual Tcl list using foreach and two variables. Line endings and whitespace don't matter when doing so, so we may keep them as is. When we're processing the lines, tag variable is assigned a tag name, and rev is a string in form of revision:hash which we can split on colon. As Tcl8.4 lacks lassign command, and using lindex makes code a bit less readable, we use foreach to iterate over two-element list.

hgk: add support for phases Add support for phases. Update tests.

hgk: in popups, replace labels with window titles Replace labels with window titles. That also requires to change grid placement manager settings to compensate padding which used to be applied to now non-existent labels.

hgk: update backgroud colour when Ttk is available Ttk doesn't automatically set up Tk colour palette. Because of that, Ttk controls look differently when used together with old Tk controls. When we use Ttk controls, we first query if we have any setting for the client background, and if we do, we update Tk palette as well.

hgk: fix pop-up windows Create pop-up windows properly so they go to the floating layer in tiling window managers.

hgk: don't use fixed format for dates Don't pass -format with a date format string, use default instead so users can use their own preferences.

hgk: reformat changsets fields Rename Author to User. Rename Revision to Changeset. Put Date on its own line.

hgk: drop committer field from the UI Remove Committer field, it doesn't make sense in Hg.

test-completion: test completion of tags

debugpathcomplete: satisfy the code checker

tests: test debugpathcomplete and debuglabelcomplete

tests: rename test-debugcomplete.t to test-completion.t

pathcomplete: complete directories more conservatively Suppose we want to perform a single-level completion (i.e. without --full) of "fi" in a repo containing "fee", "fie/dead", "fie/live", and "foe". If we give back "fie/" as the only answer, the shell will consider the completion to be unambiguous, and will append a space after the completion. We can't complete "fie/live" or "fie/dead" without first backspacing over that space. We used to thus create two fake names, "fie/a" and "fie/b", to force the shell to consider the completion to be ambiguous. It would then stop at "fie/" without appending a space, allowing us to hit tab again to complete "fie/live" or "fie/dead". The change here arises from realising that we only need to force the shell to consider a completion as ambiguous if we have exactly one directory and zero files as possible completions. This prevents spurious names from showing up as possible completions when they don't need to be invented in the first place.

sadclown: another test failure eluded me

bash_completion: recognize normal command abbreviations In many common cases, this eliminates a call to "hg help" to get a complete command name, thus improving responsiveness.

completion: selectively use debugpathcomplete in bash_completion The current bash_completion code can be very slow in a large working directory. It always uses "hg status" to generate possibly matching files, which checks the status of every file. We often don't care about status when completing, so that cost is very high. As the new debugpathcomplete command does not check the status of files, it offers much better performance for commands that only care about completing names.

completion: add a debugpathcomplete command The bash_completion code uses "hg status" to generate a list of possible completions for commands that operate on files in the working directory. In a large working directory, this can result in a single tab-completion being very slow (several seconds) as a result of checking the status of every file, even when there is no need to check status or no possible matches. The new debugpathcomplete command gains performance in a few simple ways: * Allow completion to operate on just a single directory. When used to complete the right commands, this considerably reduces the number of completions returned, at no loss in functionality. * Never check the status of files. For completions that really must know if a file is modified, it is faster to use status: hg status -nm 'glob:myprefix**' Performance: Here are the commands used by bash_completion to complete, run in the root of the mozilla-central working dir (~77,000 files) and another repo (~165,000 files): All "normal state" files (used by e.g. remove, revert): mozilla other status -nmcd 'glob:**' 1.77 4.10 sec debugpathcomplete -f -n 0.53 1.26 debugpathcomplete -n 0.17 0.41 ("-f" means "complete full paths", rather than the current directory) Tracked files matching "a": mozilla other status -nmcd 'glob:a**' 0.26 0.47 debugpathcomplete -f -n a 0.10 0.24 debugpathcomplete -n a 0.10 0.22 We should be able to further improve completion performance once the critbit work lands. Right now, our performance is limited by the need to iterate over all keys in the dirstate.

tests: add new command to test-debugcomplete

completion: add a debuglabelcomplete command When completing a "label" (a symbolic name for a commit), the bash_completion script currently has to invoke hg three times. For a large repository, the cost of starting up and loading all the necessary context over and over is very high. For instance, in mozilla-central: time (export HGPLAIN=1; hg tags -q; hg bookmarks -q; hg branches) >/dev/null 0.446 sec Compare with the debuglabelcomplete command that this commit adds: time hg debuglabelcomplete >/dev/null 0.148 sec This greatly helps responsiveness.

bash_completion: nuke a duplicated function

run-tests: only sort files when not given as argument os.listdir returns the files in any order. This has to be sorted. But when given as argument, the user should be allowed to set any order. This restores the behaviour before 9848a94e2a.

blackbox: use util.getuser for portability On Windows, our implementation is more robust than Python's version.

blackbox: prevent failed I/O from causing hg to abort Instead, we simply print a warning message if opening the blackbox log file fails, or if writing to it fails.

largefiles: don't query the dirstate for key None lfutil.splitstandin(f) can be None, and we query the dirstate for that without checking if it is. This will cause problems with the upcoming move to critbit- based dicts, since they only support strings as keys.
