convert: config option for git rename limit By default, Git applies rename and copy detection to 400 files. The diff.renamelimit config option and -l argument to diff commands can override this. As part of converting some repositories in the wild, I was hitting the default limit. Unfortunately, the warnings that Git prints in this scenario are swallowed because the process running functionality in common.py redirects stderr to /dev/null by default. This seems like a bug, but a bug for another day. This commit establishes a config option to send the rename limit through to `git diff-tree`. The added tests demonstrate a too-low rename limit doesn't result in copy metadata being recorded.

chgserver: override runcommand Next patches will customize chgserver's runcommand. So let's override it. The docstring is temporarily missing and will be filled later.

chgserver: store csystem separately Previously, the "system" channel is inside the ui object. In the future, chg will let dispatch to create a new ui object from scratch, to maximize compatibility. And chgserver will use a "uisetup" like an extension to wrap ui.system. To be able to do that cleanly, the system channel needs to be accessed directly.

py3: replace sys.platform with pycompat.sysplatform (part 2 of 2)

py3: replace sys.platform with pycompat.sysplatform (part 1 of 2) sys.platform returns unicode on python 3 world. Our code base has most of the things bytes because of the transformer. So we have a bytes version of this as pycompat.sysplatform. This series of 2 patches replaces occurences of sys.platform with pycompat.sysplatform.

py3: replace os.name with pycompat.osname (part 2 of 2)

py3: replace os.name with pycompat.osname (part 1 of 2) os.name returns unicodes on py3 and we have pycompat.osname which returns bytes. This series of 2 patches will change every ocurrence of os.name with pycompat.osname.

py3: replace os.environ with encoding.environ (part 5 of 5)

py3: replace os.environ with encoding.environ (part 4 of 5)

py3: replace os.environ with encoding.environ (part 3 of 5)

py3: replace os.environ with encoding.environ (part 2 of 5)

py3: replace os.environ with encoding.environ (part 1 of 5) os.environ is a dictionary which has string elements on Python 3. We have encoding.environ which take care of all these things. This is the first patch of 5 patch series which tend to replace the occurences of os.environ with encoding.environ as using os.environ will result in unusual behaviour.

tests: exclude bundled pywatchman from check-code test pywatchman is imported from upstream and therefore fails to pass linting. We have added 'no-check-code' manually to every file in the past. This is cumbersome and modifies upstream sources.

convert: parse perforce data on-demand We are using read-only attributes that parse the perforce data on demand. We are reading the data only once whenever an attribute is requested and use it throughout the import process. This is equivalent to the previous behavior, but we are avoiding reading from perforce when we initialize the object, but instead run it during the actual import process, when the first attribute is requested (usually getheads(), see `convertcmd.convert`).
