Summary:
No easy way to put these in the hash extension since we don't really support optional
parameters to certain algorithms. Implemented in openssl for now since it has it already
and is pretty stable.
Only SHA1 is confirmed to work as an algorithm but openssl has a parameter so it can be
changed in the future.
Will backport to 5.4 potentially with Stas' approval.
Test Plan:
Ran newly added tests which came from RFC 6070
Main Changes:
- Implement a socket transport layer for use by all code that needs to open
some kind of "special" socket for network or IPC.
- Extensions can register (and override) transports.
- Implement ftruncate() on streams via the ioctl-alike option interface.
- Implement mmap() on streams via the ioctl-alike option interface.
- Implement generic crypto API via the ioctl-alike option interface.
(currently only supports OpenSSL, but could support other SSL toolkits,
and other crypto transport protocols).
Impact:
- tcp sockets can be overloaded by the openssl capable sockets at runtime,
removing the link-time requirement for ssl:// and https:// sockets and
streams.
- checking stream types using PHP_STREAM_IS_SOCKET is deprecated, since
there are now a range of possible socket-type streams.
Working towards:
- socket servers using the new transport layer
- mmap support under win32
- Cleaner code.
# I will be updating the win32 build to add the new files shortly
# after this commit.
