-Subject: [PATCH] Rewrite url::recvline to be nonrecursive
-
-This function processes network input. It's semi-trusted, because the
-PAC ought to be trusted. But we still shouldn't allow it to control how
-far we recurse. A malicious PAC can cause us to overflow the stack by
-sending a sufficiently-long line without any '\n' character.
-
-Also, this function failed to properly handle EINTR, so let's fix that
-too, for good measure.
-
-Fixes #134
-

-Subject: [PATCH] Fix buffer overflow when PAC is enabled
-
-The bug was found on Windows 10 (MINGW64) when PAC is enabled. It turned
-out to be the large PAC file (more than 102400 bytes) returned by a
-local proxy program with no content-length present.
