Summary: Be a better citizen under system python path. Fix all tests issues and change setup.py to use glob pattern to include all extensions. Test Plan: Run tests and `make local`. Also build and install the package and run `hg sl` in major repos.

Loading order for extensions.
|
|
|
|
In the extorder section of your hgrc you can define order of extension loading.
|
|
For example:
|
|
[extorder]
|
|
extension1 = extension3, extension4
|
|
extension2 = extension1
|
|
|
|
This will cause the extension1 to be loaded after 3 and 4. Also extension2 will
|
|
be loaded after extension1.
|
|
|
|
Also there are two special configs in this section: 'preferlast' and
|
|
'preferfirst'. Those are lists of extensions which prefer to be loaded first or
|
|
last. But these are not guaranteed -- normal dependencies have higher priority.
|
|
|
|
Please not that this extension modifies only order of loading extensions. It
|
|
will not load them for you
