hg-ssh: copy doc string to man page
This corrects a warning from lintian that we're shipping an executable without
a man page. Since there is a doc string in the text, let's use that for the man
page.
progress: stop excessive clearing (
issue4801)
The progress bar was being cleared on every write(), regardless of
whether it was currently displayed. This could foul up the display of
any writes that didn't include a linebreak.
In particular, the win32 mode of the color extension was turning
single prompt string writes into two writes, and the resulting
clear/write/clear/write pattern was making the prompt invisible.
We fix this by insisting that we have shown a progress bar and haven't
just cleared it (setting lastprint to 0).
Conveniently, the test suite already had instances of duplicate
clears.. that are now cleared up.
chgserver: remove _clearenvaliases
Since we expand environment variables in alias lazily, the _clearenvaliases
hack is no longer necessary.
This resolves an issue that a non-shell alias which has environment variables
in its arguments and is set to use pager will not use pager running with chg.
dispatch: defer environment variable resolution in alias commands (BC)
Before this patch, if there are environment variables in an alias command,
they will be expanded immediately when we first see the alias.
This will cause issues with chg, because environment variable updates will
not propagate to expanded arguments.
This patch makes "args" of "cmdalias" a property that will be calculated
every time when accessed.
rollback: add a config knob for entirely disabling the command
This is of pretty high value for organizations that used to use p4 (as
an example), since `p4 rollback` is what we call `hg backout`.
templater: add separate() template function
A pretty common pattern in templates is adding conditional separators
like so:
{node}{if(bookmarks, " {bookmarks}")}{if(tags, " {tags}")}
With this patch, the above can be simplified to:
{separate(" ", node, bookmarks, tags)}
The function is similar to the already existing join(), but with a few
differences:
* separate() skips empty arguments
* join() expects a single list argument, while separate() expects
each item as a separate argument
* separate() takes the separator first in order to allow a variable
number of arguments after it
