cmdserver: forcibly use L channel to read password input (issue3161)...
cmdserver: forcibly use L channel to read password input (issue3161) Command server is designed to use the channel protocol even if the server process is accessible to tty, whereas vanilla hg should be able to read password from tty in that case. So it isn't enough to swap sys.stdin: # works only if the server process is detached from the console sys.stdin = self.fin getpass.getpass('') sys.stdin = oldin or test isatty: # vanilla hg can't talk to tty if stdin is redirected if self._isatty(self.fin): return getpass.getpass('') else: ... Since ui.nontty flag is undocumented and command-server channels don't provide isatty(), this change won't affect the other uses of ui._isatty(). issue3161 also suggests to provide some context of messages. I think it can be implemented by using the generic templating function.

Mercurial allows you to customize output of commands through
templates. You can either pass in a template from the command
line, via the --template option, or select an existing
template-style (--style).
You can customize output for any "log-like" command: log,
outgoing, incoming, tip, parents, heads and glog.
Five styles are packaged with Mercurial: default (the style used
when no explicit preference is passed), compact, changelog, phases
and xml.
Usage::
$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable
expansion::
$ hg log -r1 --template "{node}\n"

Strings in curly braces are called keywords. The availability of
keywords depends on the exact context of the templater. These
keywords are usually available for templating a log-like command:
.. keywordsmarker
The "date" keyword does not produce human-readable output. If you
want to use a date in your output, you can use a filter to process
it. Filters are functions which return a string based on the input
variable. Be sure to use the stringify filter first when you're
applying a string-input filter to a list-like input variable.
You can also use a chain of filters to get the desired output::
$ hg tip --template "{date|isodate}\n"

List of filters:
.. filtersmarker
Note that a filter is nothing more than a function call, i.e.
``expr|filter`` is equivalent to ``filter(expr)``.
In addition to filters, there are some basic built-in functions:
- date(date[, fmt])
- fill(text[, width])
- get(dict, key)
- if(expr, then[, else])
- ifcontains(expr, expr, then[, else])
- ifeq(expr, expr, then[, else])
- join(list, sep)
- label(label, expr)
- revset(query[, formatargs])
- rstdoc(text, style)
- shortest(node)
- strip(text[, chars])
- sub(pat, repl, expr)
Also, for any expression that returns a list, there is a list operator:
- expr % "{template}"
Some sample command line templates:
- Format lists, e.g. files::
$ hg log -r 0 --template "files:\n{files % ' {file}\n'}"
- Join the list of files with a ", "::
$ hg log -r 0 --template "files: {join(files, ', ')}\n"
- Format date::
$ hg log -r 0 --template "{date(date, '%Y')}\n"
- Output the description set to a fill-width of 30::
$ hg log -r 0 --template "{fill(desc, '30')}"
- Use a conditional to test for the default branch::
$ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
'on branch {branch}')}\n"
- Append a newline if not empty::
$ hg tip --template "{if(author, '{author}\n')}"
- Label the output for use with the color extension::
$ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"
- Invert the firstline filter, i.e. everything but the first line::
$ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"
- Display the contents of the 'extra' field, one per line::
$ hg log -r 0 --template "{join(extras, '\n')}\n"
- Mark the current bookmark with '*'::
$ hg log --template "{bookmarks % '{bookmark}{ifeq(bookmark, current, \"*\")} '}\n"
- Mark the working copy parent with '@'::
$ hg log --template "{ifcontains(rev, revset('.'), '@')}\n"
