Summary: D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`. That has nasty problems if both `import mercurial` and `import edenscm.mercurial` are used, because Python would think `mercurial.foo` and `edenscm.mercurial.foo` are different modules so code like `try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)` would fail to handle the `edenscm.mercurial` version. There are also some module-level states (ex. `extensions._extensions`) that would cause trouble if they have multiple versions in a single process. Change imports to use the `edenscm` so ideally the `mercurial` is no longer imported at all. Add checks in extensions.py to catch unexpected extensions importing modules from the old (wrong) locations when running tests.

"""syntax highlighting for hgweb (requires Pygments)
|
|
|
|
It depends on the Pygments syntax highlighting library:
|
|
http://pygments.org/
|
|
|
|
There are the following configuration options::
|
|
|
|
[web]
|
|
pygments_style = <style> (default: colorful)
|
|
highlightfiles = <fileset> (default: size('<5M'))
|
|
highlightonlymatchfilename = <bool> (default False)
|
|
|
|
``highlightonlymatchfilename`` will only highlight files if their type could
|
|
be identified by their filename. When this is not enabled (the default),
|
|
Pygments will try very hard to identify the file type from content and any
|
|
match (even matches with a low confidence score) will be used.
