Configuration from the outer repo is inherited to the patches repo when --mq is
used.
In case the patches repo only has paths.default configured but the outer repo
has paths.default-push then the inherited default-push will win. Very
confusing.
Inheriting the default paths is however wrong in all sane cases, so now we
explicitly remove them.
Hgs signal handler will catch the signal for example if the terminal hg is
running in is closed. That will make it try to warn that it was 'killed', but
that might fail with EIO and cause hg to exit with an unhandled exception.
Normally nobody cares, but system error handlers such as Fedoras abrt will
notice and report https://bugzilla.redhat.com/show_bug.cgi?id=596594 .
This new configuration variable is similar in nature `ui.interactive',
but applying to output instead of input. This allows as to support
non-interactive sessions where formatted should be enabled, such as
when using the pager extension.
The variable itself is left undocumented; it is not intended for use
outside Mercurial and its extensions.
Some implementations of ui.label() (HTML versions in particular) must escape
the provided text and then markup the text with their tags. When this marked
up text is then passed to ui.write(), we must label the text as 'ui.labeled'
so the implementation knows not to escape it a second time (exposing the initial
markup).
This required the addition of a 'ui.plain' label for text that is purposefully
not marked up.
I was a little pedantic here, passing even ' ' strings to ui.label() when it
would be included with other labeled text in a ui.write() call. But it seemed
appropriate to lean to the side of caution.
note: expansion of config variables must be handled on a case-by-case basis
because they can contain arbitrary data that may not be desirable to expand.
Several places that use ui.configlist, predominantly in authentication
scenarios need to interface with systems that can contain spaces in usernames
(e.g. when client certificates are usernames, or Windows usernames).
This changeset introduces a parser that supports quoting of strings, and
escape quotation marks that get decoded into a single quotation mark that
adopts the usual behavior one would expect from quoting strings. The Python
library shlex module is not used, on purpose, as that raises if it cannot
match quotation marks in the given input.
This adds output labeling support with the following methods:
- ui.write(..., label='topic.name topic2.name2 ...')
- ui.write_err(.., label=...)
- ui.popbuffer(labeled=False)
- ui.label(msg, label)
By adding an API to label output directly, the color extension can forgo
parsing command output and instead override the above methods to insert
ANSI color codes. GUI tools can also override the above methods and use
the labels to do GUI-specific styling.
popbuffer gains a labeled argument that, when set to True, returns its
buffered output with labels handled. In the case of the color extension,
this would return output with color codes embedded. For existing users
that use this method to capture and parse output, labels are discarded
and output returned as normal when labeled is False (the default).
Existing wrappers of ui.write() and ui.write_err() should make sure to
accept its new **opts argument.
If HGPLAIN is set, the following settings are ignored when read from
hgrc files:
- ui.debug
- ui.fallbackencoding
- ui.quiet
- ui.traceback
- ui.verbose
- defaults.*
Localization is also disabled.
Equivalent options set via command line are honored.
4262f8a58f24 introduced a fix if sys.stdout.closed does not exist.
This change uses a getattr with default instead of hasattr (which just calls
getattr) and accessing the attribute.
Additionally it applies the same fix for sys.stderr.closed as this is not
available in the bpython shell (reported by Roger Gammans).
Prior to this change, if a Python hook module failed to load (e.g. due
to an import error or path problem), it was impossible to figure out
why the error occurred, because the ImportErrors that got raised were
caught but never displayed.
If run with --traceback or ui.traceback=True, hg now prints tracebacks
of both of the ImportError instances that get raised before it bails.
We regularly see people on IRC ask how they can correct commits they
accidentally made without having configured a username. This change
will make Mercurial abort when a commit is made without a username.
If Mercurial is run without a TTY (from a cronjob or similar), a
username is constructed as usual. Schematically the changes are as
follows:
With ui.askusername=False:
old new
interactive user@host abort
noninteractive user@host user@host
With ui.askusername=True:
old new
interactive prompt prompt
noninteractive user@host user@host
ui.prompt was completely silent in non-interactive mode, unless in verbose
mode. It is fine that it chooses the default automatically, but it is confusing
that the message and prompt shown interactively can't be found in scripted
tests.
The prompt and selection is now .write'ed instead of .note'ed.
The fstat function was undefined, but never used since a stat object
was always passed in the optional st argument. Passing st is now
mandatory.
This bug crept in when util was split up into posix and windows
modules. The fstat function is still defined in util, but importing it
into posix would create an import cycle which seems unnecessary.
The property returns os.environ by default, and is propagated by ui.copy.
During hgweb processing, ui.environ is set to the proper WSGI-request
environment, as contained in wsgirequest.environ. For CGI, this is the
same as os.environ.
The property is meant to be read-only, as with os.environ (generally).
The built-in None object is a singleton and it is therefore safe to
compare memory addresses with is. It is also faster, how much depends
on the object being compared. For a simple type like str I get:
| s = "foo" | s = None
----------+-----------+----------
s == None | 0.25 usec | 0.21 usec
s is None | 0.17 usec | 0.17 usec
This cleans up code and allows specification of values more globally. For
example, it's now possible to specify web.contact in webdir-conf for all
repositories without a specified contact set.
Use ampersands (&) to delineate the response char in each choice.
ui.prompt() responses are now explicitly case insensitive. GUIs
that subclass ui can generate dialogs from the full choice names.
When ui.askusername is set and not username are specified on the command line,
in hgrc or in the variables $HGUSER or $EMAIL, then hg will prompt for the
username.
Feature requested, and documentation provided by Mark Edgington.
- open pipe in binary mode
- don't start a pager if stdout is not a tty (this prevents test-ssh
from hanging if you set ui.usepager=True in run-tests.py)
Unix systems usually have a PAGER environment variable set.
If it is set, mercurial will use the pager application to display
output.
Two configuration variables are available to influence the behaviour of the
pager. ui.pager sets the pager application. The pager is
only used if ui.usepager is true. By default ui.usepager is disabled.
Python already lets one to embed RE flags directly in a regex, which
is a much nicer way to do things:
(?iLmsux)
(One or more letters from the set "i", "L", "m", "s", "u", "x".)
...
matchflags was introduced in 14a7e862c60f, and the record extension is the only
user. I've killed matchflag, and adjusted record code appropriately.
Since change 0f20f68c768c, Mercurial has set_binary() on stdin, stdout, and stderr.
On Windows, this had the side effect of causing raw_input() to emit trailing carriage
returns on it's returned strings. This was causing web authentication problems.
WSGI applications are not supposed to refer to sys.stdin. In af5aceab19f4,
hgweb and hgwebdir were fixed to pass interactive=False to their ui()'s, but
sys.stdin.isatty() was still called by the ui objects. This change makes sure
only the ui.fixconfig() method will call ui.isatty() (by making the
ui._readline() method, which is currently only called from ui.prompt(),
private). ui.fixconfig() is changed to let config files override the initial
interactivity setting, but not check isatty() if interactive=False was
specified in the creation of the ui.
This untrusted configparser is a superset of the trusted configparser,
so that interpolation still works.
Also add an "untrusted" argument to ui.config* to allow querying
ui.ucdata.
With --debug, we print a warning when we read an untrusted config
file, and when we try to access a trusted setting that has one value
in the trusted configparser and another in the untrusted configparser.
The list of trusted users and groups is specified in the [trusted]
section of a hgrc; the current user is always trusted; "*" can be
used to trust all users/groups.
Global hgrc files are always read.
On Windows (and other systems that don't have the pwd and grp modules),
all .hg/hgrc files are read.
This is essentially the same patch that was previously applied as
revision f077d29b114d.
This change has the potential to break existing setups, but the current
behaviour (the keys in configuration files are always lower-cased) can
bite us in a few places:
- no way to use a Command in [defaults]
- hgext.Extension doesn't work in [extensions]
- you can't use an Upper/case/PATH in the [paths] section of hgweb.config
- you can't (easily) protect paths with upper-case letters with the
acl extension
- you can't specify a /Path/TO/a/rEPO in the [reposubs] section for
the notify extension
- ui.quiet/verbose/debug/interactive become just a cache of the ui.cdata
settings
- the quiet, verbose, debug and interactive options from the [ui] section
from .hg/hgrc files are respected for commands that open the repo
- setting ui.quiet/verbose/debug/interactive with --config works
- the command line options always override the hgrc settings - previously
it wasn't possible to override a [ui] debug = True. --debug still
takes precedence over --quiet and --verbose.
The code in ui.updateopts that handles ui.quiet, ui.verbose and
ui.debugflag is too smart, making it somewhat hard to see what
are the exact constraints placed on the values of these variables,
hiding some buglets.
This patch makes these constraints more explicit, fixing these
buglets and changing the behaviour slightly. It also adds a test
to make sure things work as expected in the future.
The buglets:
- setting ui.debug = True in a hgrc wouldn't turn on verbose mode
- additionally, setting ui.quiet = True or using --quiet would give
you a "quiet debug" mode.
The behaviour change:
- previously, in a hgrc file, ui.quiet wins against ui.verbose (i.e.
the final result would be quiet mode), but --verbose wins against
--quiet
- now ui.quiet nullifies ui.verbose and --verbose nullifies --quiet.
As a consequence, using -qv always gives you normal mode (unless
debug mode was turned on somewhere)
Previously, we would normalize settings (e.g. turn relative paths into
absolute ones) only after reading a config file.
Now "--config paths.foo=bar" will use the cwd to make "bar" an absolute
path.
The list of trusted users and groups is specified in the [trusted]
section of a hgrc; the current user is always trusted; "*" can be
used to trust all users/groups.
Global hgrc files are always read.
On Windows (and other systems that don't have the pwd and grp modules),
all .hg/hgrc files are read.
rename commands.dodiff to patch.diff.
rename commands.doexport to patch.export.
move some functions from commands to new mercurial.cmdutil module.
turn list of diff options into mdiff.diffopts class.
patch.diff and patch.export now has clean api for call from 3rd party
python code.
str.find return -1 when the substring is not found, -1 evaluate
to True and is a valid index, which can lead to bugs.
Using alternatives when possible makes the code clearer and less
prone to bugs. (and __contains__ is faster in microbenchmarks)
in interactive mode, mercurial now asks the user for the username and
password when the server requires it. the previous behavior was to fail
with an http 401.

revlogng results in smaller indexes, can address larger data files, and
supports flags and version numbers.
By default the original revlog format is used. To use the new format,
use the following .hgrc field:
[revlog]
# format choices are 0 (classic revlog format) and 1 revlogng
format=1
