dirstate: split the foldmap into separate ones for files and directories
Computing the set of directories in the dirstate can be pretty expensive. For
'hg status' without arguments, it turns out we actually never need to figure
out the right case for directories in the foldmap. (An upcoming patch explains
why.)
This patch splits up the directory and file maps into separate ones, allowing
for the subsequent optimization in status.
dirstate: introduce function to normalize just filenames
This will be used in upcoming patches to stop generating the set of directories
in many common cases.
dirstate: factor out code to discover normalized path
In upcoming patches we're going to reuse this code. The storemap is currently
always the foldmap, but will vary in future patches.
dirstate: don't require exact case when adding dirs on icasefs (
issue4578)
We don't require it when adding files on a case insensitive filesystem, so don't
require it to add directories for consistency.
The problem with the previous code was that _walkexplicit() was only returning
the normalized directory. The file(s) in the directory are then appended, and
passed to the matcher. But if the user asks for 'capsdir1/capsdir', the matcher
will not accept 'CapsDir1/CapsDir/AbC.txt', and the name is dropped. Matching
based on the non-normalized name is required.
If not normalizing, skip the extra string building for efficiency. '.' is
replaced with '' so that the path being tested when no file is specified, isn't
prefixed with './' (and therefore fail the match).
color: fix crash in cmd.exe
When 'term' is None because it isn't in the environment, don't iterate over it.
Unfortunately, unsetting $TERM or exporting it as '' doesn't work in the tests,
so there's no way to simulate cmd.exe in the test suite.
