Usage:
php_stream *stream = php_stream_fopen("/path/to/file", "r+b", NULL,
STREAM_OPEN_PERSISTENT | ENFORCE_SAFE_MODE | REPORT_ERRORS);
the filename and mode are combined to form the hash key for the persistent
list; they must be identical for this same stream to be returned again in the
next request.
Calling php_stream_close() on a persistent stream *will* close it, as is
usual with all persistent resources in PHP/ZE.
This is deliberately *not* exposed to user-space PHP at this time.
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.
