Previously, _hg_shelves used the unshelve command to list current shelves. This
is actually the wrong command. The correct usage is 'hg shelve -l' so we use
that instead.
Previously, if there was a directory between the file and first-level directory (e.g. 'bar' in
foo/bar/file), then bash_completion would only list 'foo/file' instead of 'foo/bar/file'.
This behavior was introduced in ed00ea08afda to fix spaces in file names. In
this patch, we keep that behavior while also fixing subdirectory completion by
reverting ed00ea08afda and instead add backslashes to whitespace manually. This
approach means adding the completion option 'nospace' since we do this manually
now.
This solves an issue for users that have "alias hg='hg --some_opts'" where they
would see wrong entries in the completion output (such as color codes).
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.
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.
Previously, we only completed files that had already been manually
deleted. That behaviour made no sense. We now complete unmodified,
modified, and deleted files.
This greatly helps completion performance for most commands that deal
with files.
In a working dir with 150,000 files, where we want to complete the name
of a modified file under a path beginning with "a", from the root of
the working dir:
(old) hg status -nm . 1.7 sec
(new) hg status -nm "glob:a**" 0.3
Even "hg add" becomes a little faster, in spite of being the worst
case (matching untracked files).
Since bookmarks moved into core and are no longer merged with the list
of tags (8e2d23f4bd25), they don't get completed in bash_completion
along with other revision specifiers. This adds a new function to
provide the list of bookmarks for completion, and another, _hg_labels(),
to list all tags, branches, and bookmarks. It further modifies
completion for all commands where '_hg_tags; _hg_branches' was used to
use '_hg_labels' instead.
The selection is somewhat arbitrary. In the case of the Zsh completion
file, it will not conflict with the builtin Zsh completions: they
are in a file named `_mercurial', not `_hg'.
