dispatch: do not close stdout and stderr, just flush() instead Since 3a4c0905f357 "util: always force line buffered stdout when stdout is a tty", we have two file objects attached to the same STDOUT_FILENO. If one is closed, the underlying file descriptor is also closed, and writing to the other file object would crash the Python interpreter in a hard way, at least on Windows. So, it seems safer to not close the standard streams. This also matches the behavior of the default sys.stdout/stderr.close(), which never close the FILE* streams in C layer. https://hg.python.org/cpython/file/v2.7.13/Python/sysmodule.c#l1401

windows: do not close stdout on flush() failure It's been there since e817c68edfed (2007-02-19), but seems wrong since any I/O operations to a closed file would raise ValueError, not IOError. We should keep the file object open even if the underlying file descriptor is half dead.

test-obsolete-bundle-strip: do not include \n in filename (issue5586)

revlog: add support for partial matching of wdir node id The idea is simple. If the given node id prefix is 'ff...f', add +1 to the number of matches (e.g. ambiguous if partial + maybewdir > 1). This patch also fixes id() revset and shortest() template since _partialmatch() can raise WdirUnsupported exception.

revset: add support for branch(wdir()) and wdir() & branch()

dirstate: add docstring for invalidate This always confuses me, and we already have a docstring on localrepo.invalidatedirstate.
