run-tests: track start and end time of tests We currently have information about how long each test took, but we have no data about their actual scheduling. So we now track when a test started and stopped (in the referential of the whole tests run) to expose this information. The data is currently in the json only because the json output is meant to be extensible. Later changeset will includes this data in the text output and we will be happy to bikeshed its formating there. Yes, "end" is actually just "start" + "time", but computing it an including it in the output is simple, cheap and convenient.

templater: look for mapfiles in template paths This will allow %include statements to search the default template paths in addition to the directory where the %including file is.

config: give it an includepaths option for looking for config files It is desirable to "derive" templates from the provided templates. A simple way to do this is e.g. %include map-cmdline.default in your own mapfile. Then you only have to redefine a few templates instead of copying over the whole thing. This %include mechanism already works for the built-in templates because by default it *only* looks for files that are in the same directory as the including mapfile. With this changeset, config grows an option to add more include paths for config files.

revset: map postfix '%' to only() to optimize operand recursively (issue4670) Instead of keeping 'onlypost' as a method, this patch rewrites it to 'only' function. This way, 'x%' always has the same weight as 'only(x)'.

dirs.c: pass C string, not Python string, to _finddir() The callers already have the C string, and although the PyString_AS_STRING() macro is probably free, this simplifies the code.

dirs.c: extract 'cpath' variable in _delpath() to match _addpath() The PyString_AS_STRING() macro is probably free, but this makes _delpath() more similar to _addpath() and simplifies the next patch.

treemanifest: store submanifest revlog per directory With this change, when tree manifests are enabled (in .hg/requires), commits will be written with one manifest revlog per directory. The manifest revlogs are stored in .hg/store/meta/$dir/00manifest.[id]. Flat manifests can still be read and interacted with as usual (they are also read into treemanifest instances). The functionality for writing treemanifest as a flat manifest to disk is still left in the code; tests still pass with '_treeinmem=True' hardcoded. Exchange is not yet implemented.

hghave: use try/except/finally

setup: use try/except/finally This will raise a syntax error for people who attempt to use Py2.4, but that's already going to fail and we have no way to keep other 2.6isms from creeping in since we've removed the check-code rules and the buildbot.

util: use try/except/finally
