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`).

convert: return calculated values from parse() instead of manpulating state

convert: move localname state to function scope

convert: use return value in parse_view() instead of manipulating state

changegroup: simplify logic around enabling changegroup 03 There was multiple spot that took care of adding '03' as supported changegroup version for different condition. We gather them all in one location for simplicity. The 'supportedincomingversions' function is now doing nothing, but I kept it around because it looks like a great hooking point for extension. (Note that we should probably just get changegroup3 out of experimental now, But that would be a patch with a much wider scope).

changegroup: pass 'repo' to allsupportedversions In the next changesets, we will introduce more logic directly related to the repository to decide what version have to be supported. So we now directly pass the repo object instead of just ui.

changegroup: simplify 'allsupportedversions' logic Discarding '03' to add it back is a bit strange. Instead we only discard it when needed.

py3: replace os.altsep with pycompat.altsep All the occurences of os.altsep are replaced with pycompat.altsep which returns bytes.

py3: have a bytes version of sys.platform sys.platform returns unicodes on Python 3. This patch adds up pycompat.sysplatform which returns bytes.

py3: have a bytes version of os.altsep os.altsep returns unicodes on Python 3. We need a bytes version hence added pycompat.altsep.
