graphlog: Print . instead of @ for working directory parents "." is accepted as an alias for the first working directory parent by -r/--rev

Remove atomicfile class. The interface provided by opener(atomic=True) is inherently unsafe: if an exception is raised in the code using the atomic file, the possibly incomplete file will be renamed to its final destination, defeating the whole purpose of atomic files. To get around this, we would either need some bad hacks involving sys.exc_info (to make sure things work in except: blocks), or an interface to say "file is complete; rename it". This is the exact interface provided by atomictempfile. Since there are no remaining users of the atomicfile class, just remove it.

Use atomictemp files to write the dirstate. atomic files are not safe in all cases.

test-serve: let run-tests.py kill the daemons If the daemons die while the tests are still running, we'll get additional "killed!" messages, making the test fail.

patch.diff: avoid calling workingctx().manifest() Right now, to generate the manifest of the working dir, we have to perform a full walk of the working dir, which will be very slow, especially if we're interested in only a small part of it. Since we use the manifest only to find out the mode of files for git patches, manually build an execf function to do it. This should fix issue567.

Introduce find_exe. Use instead of find_in_path for programs. The behaviour of find_in_path was broken for config options containing path names, because it always searched the given path, even when not necessary. The find_exe function is more polite: if the name passed to it contains a path component, it just returns it.

ui: Rename has_config to has_section.

patchbomb: Defer the import of readline. If imported at the top of the module, the import appears to succeed, but raw_input doesn't acquire magic editing fu. I suspect this has something to do with the newish demandimport code, because the prior code worked with demandload.
