test-hgweb: fix shutdown race
Logfiles weren't necessarily being flushed before being read.
tests: invoke hg command indirectly from shell script to run on Windows
Before this patch, test-tag.t can't run successfully on Windows,
because:
- quoted hg command ('"hg"') prevents "hg.bat" from working correctly
(only at testing with pure Python build)
"%~f0" and "%~dp0hg" in "hg.bat" cause unexpected result in this
case. BTW, quoted "\path\to\hg" works correctly.
- "`pwd`" in the command line is expanded unexpectedly
not "C:\path\to\TESTTMP" but "C;C:\path\to\TESTTMP"
log: evaluate filesets on working copy, not its parent
When running "hg log 'set:added()'", we create two matchers: one used
for producing the revset and one used for finding files to match. In
1fd352aa08fc (graphlog: evaluate FILE/-I/-X filesets on the working
dir, 2012-02-26), we started passing a revision argument along from
what's currently in cmdutil._makelogrevset() to
revset._matchfiles(). When the revision was an empty string, it
referred to the working copy. This was subtly done with "repo[rev or
None]". Then, in
f2aeff8a87b6 (revset: avoid recalculating filesets,
2014-10-22), that conversion from empty string to None was lost. Note
that repo[''] is equivalent to repo['.'], not repo[None].
The consequence of this, to the user, is that when running "hg log
'set:added()'", the file matcher matches files added in the working
copy, while the revset matcher matches revisions that touch files
added in the parent of the working copy. As a result, only revisions
that touch any files added in the parent of the working copy will be
considered, but they will only be included if they also touch files
added in the working copy.
Fix the bug by converting '' to None again, but make it a little more
explicit this time (plus, we now have tests for it).
