Summary: In the future `python` will no longer be able to import `bindings`. Change them to `hg debugpython` so they stay compatible. I dropped the "custom hghave" feature. It breaks and I don't think there are users of it. Reviewed By: singhsrb Differential Revision: D17429689 fbshipit-source-id: 96e55ef25a027bd4ad33fc279f27c1d5cbed6861

revlog.parseindex must be able to parse the index file even if
|
|
an index entry is split between two 64k blocks. The ideal test
|
|
would be to create an index file with inline data where
|
|
64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
|
|
the size of an index entry) and with an index entry starting right
|
|
before the 64k block boundary, and try to read it.
|
|
We approximate that by reducing the read buffer to 1 byte.
