Subject: [PATCH] re-enable HTML reports under Python3
d58195b
d58195b
In commit 1cc987a23, the `commonpath()` function was added, which quite
d58195b
sensibly tries to figure out real path names. Unfortunately, it uses
d58195b
`iterools.izip()` which is not available under Python3. Instead, that
d58195b
functionality is now provided by the `zip()` builtin.
d58195b
d58195b
We therefore define an `izip()` function as an alias for
d58195b
`itertools.izip()` if that is available, or else use `zip()`.
d58195b
d58195b
Since `commonpath()` is used in HTML reports, it was previously
d58195b
impossible to create HTML reports with GCOVR under Python3.
d58195b
To prevent such problems in the future, the existing HTML tests should
d58195b
be updated and enabled.
