The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
This reverts commit 13acb7ec65.
With the added capability to negotiate application layer protocols
via the TLS ALPN extension userland needs a method to access the
negotiated protocol on a given stream. The reverted commit added
a new stream_socket_crypto_info() function for this purpose.
This original approach was discarded in favor of using the
already-existing stream_get_meta_data() API which specifically
exists for just such purposes and requires the addition of no new
functions.
PHP 5.6.0 altered the semantics of the following constants:
- STREAM_CRYPTO_METHOD_SSLv23_CLIENT
- STREAM_CRYPTO_METHOD_SSLv23_SERVER
- STREAM_CRYPTO_METHOD_TLS_CLIENT
- STREAM_CRYPTO_METHOD_TLS_SERVER
Instead of representing the SSLv23_*() handshake methods the v23
constants were changed to allow only SSLv2 or SSLv3 connections.
Likewise, the TLS methods were modified from using only the TLSv1
handshake to allowing TLS1,1.1, and 1.2. This created a situation
in which users upgrading from previous versions faced a potential
security degradation if they did not update code to use different
constants. In the interest of compatibility across PHP versions
the original semantics have been restored with the following
caveat:
**IMPORTANT**
The SSLv23 client/server methods will no longer negotiate the use
of the insecure SSLv2 or SSLv3 protocols by default. Users wishing
to allow these protocols must explicitly add them to the method
bitmask via the appropriate flags.
. stream_socket_client() - similar to fsockopen(), but more powerful.
. stream_socket_server() - Creates a server socket.
. stream_socket_accept() - Accept a client connection.
. stream_socket_get_name() - Get local or remote name of socket.
Tidy up some leaks and debug printfs.
Move more streams functions into streamsfuncs.c and streamsfuncs.h.
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.
