log: don't expand aliases in revset built from command options
Only -rREV should be rewritten with user aliases.
log: remove redundant handling of --limit
A returned 'revs' set is pre-filtered by cmdutil.getlogrevs(). The result
of displayer.flush() isn't used anymore, so removed.
log: merge getlogrevs() and getgraphlogrevs()
cmdutil.graphlog() is updated to receive (revs, filematcher) as arguments
to make sure that opts['graph'] is set when getlogrevs() is invoked.
revset: parse x^:: as (x^):: (
issue5764)
We have to make '::' a valid primary expression to parse 'x^::' as '(x)^(::)'
first, but that doesn't change the language because a prefix operator '::y'
precedes a primary '::'.
I can't think of an intuitive meaning of '::', so it's just rejected. Given
'x::y' can be considered to default to {x = roots(), y = heads()}, '::' could
be 'roots()::heads()', which seems not any useful.
test-run-tests: stabilize the test (
issue5735)
Previously there is a race condition because things happen in this order:
1. Check shouldStop
2. If shouldStop is false, print the diff
3. Call fail() -> set shouldStop
The check and set should really happen in a same critical section.
This patch adds a lock to address the issue.
Test Plan:
Run `run-tests.py -l test-run-tests.t` 20 times on gcc112 and the race
condition does not reproduce.

run-tests: avoid set PYTHONUSERBASE environment variable to None
According to python documentation, get_config_var can return None and it was
during running mercurial tests under a virtual environment with the local built
mercurial installed as a python package with `pip install -e .`.
On the other hand, if mercurial is installed in the user library folders with
`pip install --local -e .` the issue doesn't reproduce.
The fallback is that it will just set an empty string and everything should work
as before, according to https://www.python.org/dev/peps/pep-0370/:
The path to the user base directory can be overwritten with the environment
variable PYTHONUSERBASE. The default location is used when PYTHONUSERBASE is
not set or empty.
