store: invoke "osutil.listdir()" via vfs This patch invokes "osutil.listdir()" via vfs object. The function added newly to "abstractvfs" is named not as "listdir()" but as "readdir()", because: - "os.listdir()" seems to be more familiar as "listdir()" than "osutil.listdir()" - "osutil.listdir()" returns also type of each files like "readdir()" POSIX API: even though "d_type" field of "dirent" structure is defined mainly only on BSD/Linux This patch invokes "osutil.listdir()" via "rawvfs" object to avoid filename encoding, because the path passed to "osutil.listdir()" shouldn't be encoded. This patch also omits importing "osutil" module, because it is no longer used.

log: speed up hg log for untracked files (issue1340) 'hg log' on untracked files tends to be fairly slow. The root cause is that we end up using the 'slowpath' when we can't find a revlog for the files listed. This could happen if the file in question is an untracked file, or it is a directory. This diff tries to speed up 'hg log' (by avoiding the slowpath) for files if we can determine if that file is not (and was never) a directory. We use the previously added store.__contains__ methods to test if the directory exists (or existed) in the store. To avoid changing any existing semantics, this 'optimization' kicks in only when none of the files listed as arguments to the hg log command exist in the store.

store: add a contains method to fncachestore Adds a __contains__ method to fncachestore to check for file/dir existence (using fncache.__contains__). Also extends fncache.__contains__ to check for directories (by prefix matching)

store: add a contains method to basicstore Adds a __contains__ method to basicstore that checks if a file/dir is present in the store

tests: drop filtercr.py and use the very explicit '\r (no-eol) (esc)' markup

run-tests: allow test output lines to be terminated with \r in addition to \n str.splitlines could not be used in 546c76e5a3e6, but _now_ we would like to have lines with other line endings than \n. Some fine occurences of (esc) markup of \r is replaced with multiple lines ending with '\r (no-eol) (esc)'. That is no win but also no significant loss. This change makes it possible to drop filtercr.py - _that_ is a win.
