py3: make check-py3-compat.py load modules in standard manner Otherwise no code transformation would be applied to the modules which are imported only by imp.load_module(). This change means modules are imported from PYTHONPATH, not from the paths given by command arguments. This isn't always correct, but seems acceptable.

py3: include module filename in check-py3-compat.py output This change is intended to reduce noises in the next patch.

util: document we want Python type mapping to be temporary I think remapping Python C API types and functions is not a great approach. I'd prefer this whole #ifdef disappeared. Add a comment so we don't forget about it.

util: define PyInt_Type on Python 3 util.h attempts to wallpaper over C API differences between Python 2 and 3. This is not the correct approach where performance is critical. But it is good enough for the current state of the Python 3 port.

parsers: return NULL from PyInit_parsers on Python 3 This function must return a PyObject* or the compiler complains.

mail: take --encoding and HGENCODING into account Fall back to our encoding strategy for sending MIME text that's neither ASCII nor UTF-8.

template: provide a termwidth keyword (issue5395) We want to provide terminal-sized output. As a starting point, expose the terminal width to the templater for use in things like fill.

util: ensure forwarded attrs are set in globals() as sysstr Custom module importer strikes again.

pycompat: when setting attrs, ensure we use sysstr The custom module importer was making these bytes, so when we poked values into self.__dict__ we had bytes instead of unicode on py3 and it didn't work.

i18n: make the locale directory name the same string type as the datapath

contributing: add new file with a pointer to the wiki This also includes what I consider to be the minimum set of steps someone should be able to perform even if they can't run the testsuite. Hopefully this will help new contributors know to at least run the two checkers that find most things that (in my experience) require manual cleanup.

templater: add relpath() to convert repo path to relative path (issue5394) File paths in template are repository-absolute paths. This function can be used to convert them to filesystem paths relative to cwd. This also converts '/' to '\\' on Windows.

hgweb: fix the MRO in Python 3 object should appear at the end, otherwise it tries to pre-empt the other new-style classes in the MRO, resulting in an unresolvable MRO in Py3. We still need to include object because otherwise in 2.7 we end up with an old-style class if threading is not supported, new-style if it is.

hgweb: make fctx.annotate a separated function so it could be wrapped This patch moves "fctx.annotate" used by the "annotate" webcommand, along with the diffopts to a separated function which takes a ui and a fctx. So it could be replaced by other implementations which don't want to replace the core "fctx.annotate" directly.

zsh_completion: update some option usage flags ('+', '=' and ':') Here are the relevant symbol descriptions from [0] optspec:... The colon indicates handling for one or more arguments to the option; if it is not present, the option is assumed to take no arguments. -optname+ The first argument may appear immediately after optname in the same word, or may appear as a separate word after the option. For example, ‘-foo+:...’ specifies that the completed option and argument will look like either ‘-fooarg’ or ‘-foo arg’. -optname= The argument may appear as the next word, or in same word as the option name provided that it is separated from it by an equals sign, for example ‘-foo=arg’ or ‘-foo arg’. There are 3 types of changes in this patch: - addition of '=': means that '--repository ~/foo' can now also be spelled as '--reporitory=~/foo' - addition of '+': means '-r 0' can now also be spelled as '-r0' - removal of '+', '=' and ':': means that '-u|--untrusted' doesn't take any arguments, so '-uq' is definitely '-u -q' and not '--untrusted=q' Occasionally, ':' had to be added together with '=' and '+'. This patch is mostly just making zsh_completion file look more like zsh's own hg completion file so that we can more easily take improvements from them or send patches to them.

manifest: drop Py_TPFLAGS_HAVE_SEQUENCE_IN from tp_flags in Python 3 This flag disappeared in Python 3. It is only necessary in Python 2, apparently.
