Previously, command line parsing of --config arguments was done in
_dispatch. This means that it takes place after activating the debugger. In an
upcoming patch, we will add a ui.debugger setting so we need to have this
parsing done before _runcatch.
Previously the blackbox wrapped runcommand, but this failed to see the error
codes that were created if an exception occurred. I moved that logging to now
wrap _runcatch, so it can observe and log the actual error code (such as when
a user ctrl+c's during a command).
Updated the tests as well. Tested the change by running all the tests with the
blackbox extension enabled and verifying nothing broke (aside from things that
printed what extensions were enabeld).
The progress tests are affected by calls to time.time() so they needed to be
updated to pass.
When running commands like 'hg export -o mypatch-%N.patch', the blackbox
would throw an exception because it tried to format %N. This change
prevents it from trying to format the command string.
As mentioned in bug 2043, --config is also not supported in an alias. So report
this the same way as the other "early" options.
Example with alias.broken = stat --config a.config=1
Before:
$ hg broken
abort: Option --config may not be abbreviated!
After:
$ hg broken
error in definition for alias 'broken': --config may only be given on the command line
User 'timeless' in irc mentioned that having the blackbox be
translated would result in logs that:
- may be mixed language, if multiple users use the same repo
- are not google searchable (since searching for english gives more
results)
- might not be readable by an admin if the employee is using hg in
his native language
And therefore we should log everything in english.
Uses ui.log to log which commands are run, their exit code, the time taken,
and any unhandled exceptions thrown.
Example log lines:
2013/02/09 08:35:19 durham> add foo
2013/02/09 08:35:19 durham> add exited 0 after 0.02 seconds
Updates the progress tests because they use a mocked time.time() which these
changes affect.
The number of output lines was hardcoded to 30.
There was a 'nested' configuration options that controlled something else
related to counting the number of output lines.
This introduces the profiling.limit configuration option for controlling the
number of profiling output to show.
We ensure all repositores created through `mercurial.hg.repository`
are "hidden" filtered. This is an even stronger enforcement than
86530c899687.
Citing Matt's response to changeset 86530c899687 installing filtering
in dispatch:
> Unfortunately, this means that code that doesn't go through dispatch (ie all
> those crazy misguided people using Mercurial as a library) are going to see
> these hidden changesets.

> Might be better to instead install the filter in localrepo construction by

The dispatch code now enables filtering of "hidden" changesets globally. The
filter is installed before command and extension invocation. The `--hidden`
switch is now global and disables this filtering for any command.
Code in log dedicated to changeset exclusion is removed as this global filtering
has the same effect.
Mercurial would sometimes exit with:
abort: No such file or directory
where str of the actual OSError exception was the more helpful:
[Errno 2] No such file or directory: ''
The exception will now always show the filename and quote it:
abort: No such file or directory: ''
When extensions had an empty `testedwith` attribute the code tried to parse it
and failed. As a result the actual error were shallowed by a This crash.
We now treat empty strip as 'unknown'
Maintain a whitelist of commands to infer the repo for instead. The whitelist
contains those commands that take file(s) in the working dir as arguments.
The "worst" extension still is the one tested with the lowest tested version
below the current version of Mercurial, but if an extension with was only
tested with newer versions, it is considered a candidate for a bad extension,
too. In this case extensions which have been tested with higher versions of
Mercurial are considered better. This allows finding the oldest extension if
ct can't be calculated correctly and therefore defaults to an empty tuple, and
it involves less changes to the comparison logic during the current code
freeze.
When developing, we may see non-standard version strings of the form
5d64306f39bb+20120525
which caused tuplever() to raise
ValueError: invalid literal for int() with base 10: '5d64306f39bb'
and shadowing the real traceback.
Extension authors should explicitly declare their supported hg
versions and include a buglink attribute in their extension. In the
event that a traceback occurs, we'll identify the
least-recently-tested extensionas the most likely source of the defect
and suggest the user disable that extension.
Packagers should make every effort to ship hg versions from exact
tags, or with as few modifications as possible so that the versioning
can work appropriately.
Commands working without a repository, like "init", are listed in
commands.norepo. Commands optionally using a repository, like "showconfig", are
listed in commands.optionalrepo. Command aliases were inheriting the former but
not the latter.
This can be selected using the config variable profiling.type or
the environment variable HGPROF ("ls" for the default, "stat" for
statprof). The only tuneable is the frequency, profiling.freq,
which defaults to 1000 Hz.
If statprof is not available, a warning is printed.
The exit code returned from a program to the shell is unsigned 8-bit, but
Mercurial would sometimes try to exit with negative numbers or None. sys.exit
on Unix will convert that to 8-bit exit codes, but on Windows negative values
showed up as 0.
The exit code is now explicitly converted to unsigned 8-bit.
Previously, if you set an alias for "ci", it'd also shadow "commit"
even though you didn't specify that. This occurred for all commands
with explicit short variations.
Previously aliases that overrode existing commands would wrap the old alias
on every call to dispatch() (twice actually), which is an obvious re-entrancy
issue for things like the command server or TortoiseHG.
Older clients will still print the provided error message and not much else:
over ssh, this will be each line prefixed with 'remote: ' in addition to an
"abort: unexpected response: '\n'"; over http, this will be the '---%<---'
banners in addition to the 'does not appear to be a repository' message.
Currently, clients with this patch will display 'abort: remote error:\n' and
the provided error text, but it is trivial to style the error text however is
deemed appropriate.
Closing here means we've closed the repo passed to us in the request,
which is not our responsibility.
This is essential for bundlerepo, and possibly other localrepository
subclasses who do something in their close().
and check if we got one before creating.
note that the contents of the ui object might change after
dispatch() returns (by options passed through --config for example),
to ensure it doesn't, pass a copy() of it.
Example
$ hg clone --jump foo bar
hg clone: option --jump not recognized
hg clone [OPTION]... SOURCE [DEST]
make a copy of an existing repository
options:
-U --noupdate the clone will include an empty working copy (only a
repository)
-u --updaterev REV revision, tag or branch to check out
-r --rev REV [+] include the specified changeset
-b --branch BRANCH [+] clone only the specified branch
--pull use pull protocol to copy metadata
--uncompressed use uncompressed transfer (fast over LAN)
-e --ssh CMD specify ssh command to use
--remotecmd CMD specify hg command to run on the remote side
--insecure do not verify server certificate (ignoring
web.cacerts config)
[+] marked option can be specified multiple times
use "hg help clone" to show the full help text
Motivation for this change
If the user already has specified the command, he probably already knows
the command to some extent. Apparently, he has a problem with the options,
so we show him just the synopsis with the short help and the details about
the options, with a hint on the last line how to get the full help text.
Why is Mercurial better with this change?
Experts who just forgot about the details of an option don't get that
much text thrown at them, while the newbies still get a hint on the last
line how to get the full help text.
This improves the misleading error message
$ hg identify
abort: there is no Mercurial repository here (.hg not found)!
to the more explicit
$ hg identify
abort: requirement 'fake' not supported!
for all commands in commands.optionalrepo, which includes the identify
and serve commands in particular.
This is for the case when a new entry in .hg/requires will be defined
in a future Mercurial release.
Add empty repository.close() and call it in dispatch.
Remove bundlerepository.__del__(), merging it into bundlerepository.close(),
which overrides repository.close().
http://docs.python.org/reference/datamodel.html says:
"It is not guaranteed that __del__() methods are called for objects that
still exist when the interpreter exits."
If --insecure specified, it behaves in the same way as no web.cacerts
configured.
Also shows hint for --insecure option when _verifycert() failed. But currently
the hint isn't displayed on SSLError, because it needs a certain level of
changes.
This patch modifies the check for shell aliases to prevent crashing when an invalid
global option is given.
When an invalid global option is given the check will simply return and let the
normal error handling for this case happen.
This patch refactors the dispatch code to change how arguments to shell aliases
are handled.
A separate "pass" to determine whether a command is a shell alias has been
added. The rough steps dispatch now performs when a command is given are these:
* Parse all arguments up to the command name.
* If any arguments such as --repository or --cwd are given (which could change
the config file used, and therefore the definition of aliases), they are
taken into account.
* We determine whether the command is a shell alias.
* If so, execute the alias. The --repo and --cwd arguments are still in effect.
Any arguments *after* the command name are passed unchanged through to the
shell command (and interpolated as normal.
* If the command is *not* a shell alias, the dispatching is effectively "reset"
and reparsed as normal in its entirety.
The net effect of this patch is to make shell alias commands behave as you
would expect.
Any arguments you give to a shell alias *after* the alias name are passed
through unchanged. This lets you do something like the following:
[alias]
filereleased = !$HG log -r 'descendants(adds("$1")) and tagged()' -l1 $2 $3 $4 $5
$ hg filereleased hgext/bookmarks.py --style compact
Previously the `--style compact` part would fail because Mercurial would
interpret those arguments as arguments to the alias command itself (which
doesn't take any arguments).
Also: running something like `hg -R ~/src/hg-crew filereleased
hgext/bookmarks.py` when `filereleased` is only defined in that repo's config
will now work.
These global arguments can *only* be given to a shell alias *before* the alias
name. For example, this will *not* work in the above situation:
$ hg filereleased -R ~/src/hg-crew hgext/bookmarks.py
The reason for this is that you may want to pass arguments like --repository to
the alias (or, more likely, their short versions like -R):
[alias]
own = !chown $@ `$HG root`
$ hg own steve
$ hg own -R steve
