/*
This module provides an interface to Berkeley socket IPC.
Limitations:
Patch #401196: IPv6 extensions to the socket module. New functions getnameinfo, getaddrinfo. New exceptions socket.gaierror, socket.herror. Various new constants, in particular AF_INET6 and error codes and parameters for getaddrinfo. AF_INET6 support in setipaddr, makesockaddr, getsockaddr, getsockaddrlen, gethost_common, PySocket_gethostbyaddr.
2001-07-21 18:05:31 +00:00
- only AF_INET, AF_INET6 and AF_UNIX address families are supported in a
SF patch 101137 from Grant Edwards Adds support for raw packets (AF_PACKET) under Linux. I haven't tested this code thoroughly; it compiles and the basic calls all work without crashing. Not sure what to actually do with raw sockets though. Not sure what other platforms this might be useful for.

portable manner, though AF_PACKET is supported under Linux.
Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

- no read/write operations (use sendall/recv or makefile instead)
- additional restrictions apply on Windows (compensated for by socket.py)

- socket.error: exception raised for socket specific errors
Patch #401196: IPv6 extensions to the socket module. New functions getnameinfo, getaddrinfo. New exceptions socket.gaierror, socket.herror. Various new constants, in particular AF_INET6 and error codes and parameters for getaddrinfo. AF_INET6 support in setipaddr, makesockaddr, getsockaddr, getsockaddrlen, gethost_common, PySocket_gethostbyaddr.
2001-07-21 18:05:31 +00:00

Socket methods:
Add gethostname() and s.avail().
1991-07-27 21:42:02 +00:00
- s.accept() --> new socket object, sockaddr
Restore strict checking of socket address values; addresses passed to the bind(), connect(), and connect_ex() methods must be a single parameter. Originally part of 1.98, reverted in 1.100.
2000-07-01 03:40:12 +00:00

fixed up comments describing interface
1995-03-16 15:43:47 +00:00
- s.fileno() --> file descriptor
More rational support for Windows (tested on Roj's NT 3.5 machine only). Use PyArg_ParseTuple() where it makes sense.
1996-06-20 16:25:29 +00:00
- s.dup() --> same as socket.fromfd(os.dup(s.fileno(), ...)
* config.c: Added audioop to lists. * Makefile: change default source directory * socketmodule.c: added getsockname and getpeername * bltinmodule.c: corrected typo in type() error message * Added new built-in functions str() and repr(): repr(x) == `x`; str(x) == x if x is a string, otherwise str(x) == repr(x). * Added joinfields to stropmodule.c (string.join calls joinfields now)

Merge alpha100 branch back to main trunk
1994-08-01 11:34:53 +00:00
- s.send(string [,flags]) --> nbytes
Add sendall() method, which loops until all data is written or an error occurs, and doesn't return a count. (This is my second patch from SF patch #474307, with small change to the docstring for send().) 2.1.2 "bugfix" candidate.
2001-10-26 03:25:00 +00:00
- s.sendall(string [,flags]) # tries to send everything in a loop
Merge alpha100 branch back to main trunk
1994-08-01 11:34:53 +00:00
- s.sendto(string, [flags,] sockaddr) --> nbytes

#include "Python.h"
Clean up pass for the previous patches. - Use HAVE_GETHOSTBYNAME_R_6_ARG instead of testing for Linux and glibc2. - If gethostbyname takes 3 args, undefine HAVE_GETHOSTBYNAME_R -- don't know what code should be used. - New symbol USE_GETHOSTBYNAME_LOCK defined iff the lock should be used. - Modify the gethostbyaddr() code to also hold on to the lock until after it is safe to release, overlapping with the Python lock. (Note: I think that it could in theory be possible that Python code executed while gethostbyname_lock is held could attempt to reacquire the lock -- e.g. in a signal handler or destructor. I will simply say "don't do that then.")

Jack Jansen: The GUSI 2.0 I/O library used on the Mac uses the socklen_t (unsigned int) for most size parameters. Apparently this is part of the UNIX 98 standard. [GvR: the changes to configure.in etc. that I just checked in make sure that socklen_t is defined everywhere, so I deleted the little part of Jack's mod to define socklen_t if not in GUSI2. I suppose I will have to add it to the Windows config.h in a minute.]

Expose three OpenSSL API calls for dealing with the PRNG. Quoth the OpenSSL RAND_add man page: OpenSSL makes sure that the PRNG state is unique for each thread. On systems that provide /dev/urandom, the randomness device is used to seed the PRNG transparently. However, on all other systems, the application is responsible for seeding the PRNG by calling RAND_add(), RAND_egd(3) or RAND_load_file(3). I decided to expose RAND_add() because it's general and RAND_egd() because it's a useful special case. RAND_load_file() didn't seem to offer much over RAND_add(), so I skipped it. Also supplied RAND_status() which returns true if the PRNG is seeded and false if not.

Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

#ifdef USE_SSL
Lots of code reorganization with a few small API changes. Change all the local names that start with SSL to start with PySSL. The OpenSSL library defines lots of calls that start with "SSL_". The calls for Python's SSL objects also started with "SSL_". This choice made it really confusing to figure out which calls were to the library and which calls were local to the file. Add PySSL_SetError() that sets an exception based on the information from SSL_get_error(). This function will eventually replace all the calls that set it with an error message that is based on the name of the call that failed rather than the reason it failed. (Example: If SSL_connect() failed it used to report "SSL_connect error" now it will offer a specific message about why SSL_connect failed.) XXX It might be helpful to augment the error message generated below with the name of the SSL function that generated the error. I expect it's obvious most of the time. Remove several unnecessary INCREFs in the module's constructor call. PyDict_SetItem() and friends do the INCREF for you.

Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)', and a couple of functions that were missed in the previous batches. Not terribly tested, but very carefully scrutinized, three times. All these were found by the little findkrc.py that I posted to python-dev, which means there might be more lurking. Cases such as this: long func(a, b) long a; long b; /* flagword */ { and other cases where the last ; in the argument list isn't followed by a newline and an opening curly bracket. Regexps to catch all are welcome, of course ;)

Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

Lots of code reorganization with a few small API changes. Change all the local names that start with SSL to start with PySSL. The OpenSSL library defines lots of calls that start with "SSL_". The calls for Python's SSL objects also started with "SSL_". This choice made it really confusing to figure out which calls were to the library and which calls were local to the file. Add PySSL_SetError() that sets an exception based on the information from SSL_get_error(). This function will eventually replace all the calls that set it with an error message that is based on the name of the call that failed rather than the reason it failed. (Example: If SSL_connect() failed it used to report "SSL_connect error" now it will offer a specific message about why SSL_connect failed.) XXX It might be helpful to augment the error message generated below with the name of the SSL function that generated the error. I expect it's obvious most of the time. Remove several unnecessary INCREFs in the module's constructor call. PyDict_SetItem() and friends do the INCREF for you.

Clean up pass for the previous patches. - Use HAVE_GETHOSTBYNAME_R_6_ARG instead of testing for Linux and glibc2. - If gethostbyname takes 3 args, undefine HAVE_GETHOSTBYNAME_R -- don't know what code should be used. - New symbol USE_GETHOSTBYNAME_LOCK defined iff the lock should be used. - Modify the gethostbyaddr() code to also hold on to the lock until after it is safe to release, overlapping with the Python lock. (Note: I think that it could in theory be possible that Python code executed while gethostbyname_lock is held could attempt to reacquire the lock -- e.g. in a signal handler or destructor. I will simply say "don't do that then.")

Trent Mick <trentm@activestate.com>: This patch fixes possible overflows in the socket module for 64-bit platforms (mainly Win64). The changes are: - abstract the socket type to SOCKET_T (this is SOCKET on Windows, int on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on Win64 - use INVALID_SOCKET on Win32/64 for an error return value for accept() - ensure no overflow of the socket variable for: (1) a PyObject return value (use PyLong_FromLongLong if necessary); and (2) printf formatting in repr(). Closes SourceForge patch #100516.

Jack Jansen: The GUSI 2.0 I/O library used on the Mac uses the socklen_t (unsigned int) for most size parameters. Apparently this is part of the UNIX 98 standard. [GvR: the changes to configure.in etc. that I just checked in make sure that socklen_t is defined everywhere, so I deleted the little part of Jack's mod to define socklen_t if not in GUSI2. I suppose I will have to add it to the Windows config.h in a minute.]

Three uses of makesockaddr() used sockaddr buffers that had not be cleared; this could cause invalid paths to be returned for AF_UNIX sockets on some platforms (including FreeBSD 4.2-RELEASE), appearantly because there is no assurance that the address will be nul-terminated when filled in by the kernel. PySocketSock_recvfrom(): Use PyString_AS_STRING() to get the data pointer of a string we create ourselves; there is no need for the extra type check from PyString_AsString(). This closes SF bug #416573.

Trent Mick <trentm@activestate.com>: This patch fixes possible overflows in the socket module for 64-bit platforms (mainly Win64). The changes are: - abstract the socket type to SOCKET_T (this is SOCKET on Windows, int on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on Win64 - use INVALID_SOCKET on Win32/64 for an error return value for accept() - ensure no overflow of the socket variable for: (1) a PyObject return value (use PyLong_FromLongLong if necessary); and (2) printf formatting in repr().

Three uses of makesockaddr() used sockaddr buffers that had not be cleared; this could cause invalid paths to be returned for AF_UNIX sockets on some platforms (including FreeBSD 4.2-RELEASE), appearantly because there is no assurance that the address will be nul-terminated when filled in by the kernel. PySocketSock_recvfrom(): Use PyString_AS_STRING() to get the data pointer of a string we create ourselves; there is no need for the extra type check from PyString_AsString(). This closes SF bug #416573.

Trent Mick <trentm@activestate.com>: This patch fixes possible overflows in the socket module for 64-bit platforms (mainly Win64). The changes are: - abstract the socket type to SOCKET_T (this is SOCKET on Windows, int on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on Win64 - use INVALID_SOCKET on Win32/64 for an error return value for accept() - ensure no overflow of the socket variable for: (1) a PyObject return value (use PyLong_FromLongLong if necessary); and (2) printf formatting in repr(). Closes SourceForge patch #100516.

#ifdef MS_WIN32
SF bug [#456252] Python should never stomp on [u]intptr_t. pyport.h: typedef a new Py_intptr_t type. DELICATE ASSUMPTION: That HAVE_UINTPTR_T implies intptr_t is available as well as uintptr_t. If that turns out not to be true, things must get uglier (C99 wants both, so I think it's an assumption we're *likely* to get away with). thread_nt.h, PyThread_start_new_thread: MS _beginthread is documented as returning unsigned long; no idea why uintptr_t was being used. Others: Always use Py_[u]intptr_t, never [u]intptr_t directly.

Py_BEGIN_ALLOW_THREADS
Three uses of makesockaddr() used sockaddr buffers that had not be cleared; this could cause invalid paths to be returned for AF_UNIX sockets on some platforms (including FreeBSD 4.2-RELEASE), appearantly because there is no assurance that the address will be nul-terminated when filled in by the kernel. PySocketSock_recvfrom(): Use PyString_AS_STRING() to get the data pointer of a string we create ourselves; there is no need for the extra type check from PyString_AsString(). This closes SF bug #416573.

Use an explicit macro SOCKETCLOSE which expands to closesocket (on Windows), soclose (on OS2), or to close (everywhere else). Hopefully this fixes a new compilation error that I suddenly get on Windows because the macro definition for close -> closesocket apparently was done before including io.h, which contains a prototype for close. (No idea why this wasn't an error before.)
2000-04-21 20:33:00 +00:00
(void) SOCKETCLOSE(s->sock_fd);
Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

Trent Mick <trentm@activestate.com>: This patch fixes possible overflows in the socket module for 64-bit platforms (mainly Win64). The changes are: - abstract the socket type to SOCKET_T (this is SOCKET on Windows, int on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on Win64 - use INVALID_SOCKET on Win32/64 for an error return value for accept() - ensure no overflow of the socket variable for: (1) a PyObject return value (use PyLong_FromLongLong if necessary); and (2) printf formatting in repr().

Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

AF_INET6 support in setipaddr, makesockaddr, getsockaddr, getsockaddrlen, gethost_common, PySocket_gethostbyaddr.

Trent Mick <trentm@activestate.com>: This patch fixes possible overflows in the socket module for 64-bit platforms (mainly Win64). The changes are: - abstract the socket type to SOCKET_T (this is SOCKET on Windows, int on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on Win64 - use INVALID_SOCKET on Win32/64 for an error return value for accept() - ensure no overflow of the socket variable for: (1) a PyObject return value (use PyLong_FromLongLong if necessary); and (2) printf formatting in repr().

Jack Jansen: The GUSI 2.0 I/O library used on the Mac uses the socklen_t (unsigned int) for most size parameters. Apparently this is part of the UNIX 98 standard. [GvR: the changes to configure.in etc. that I just checked in make sure that socklen_t is defined everywhere, so I deleted the little part of Jack's mod to define socklen_t if not in GUSI2. I suppose I will have to add it to the Windows config.h in a minute.]

Lots of code reorganization with a few small API changes. Change all the local names that start with SSL to start with PySSL. The OpenSSL library defines lots of calls that start with "SSL_". The calls for Python's SSL objects also started with "SSL_". This choice made it really confusing to figure out which calls were to the library and which calls were local to the file. Add PySSL_SetError() that sets an exception based on the information from SSL_get_error(). This function will eventually replace all the calls that set it with an error message that is based on the name of the call that failed rather than the reason it failed. (Example: If SSL_connect() failed it used to report "SSL_connect error" now it will offer a specific message about why SSL_connect failed.) XXX It might be helpful to augment the error message generated below with the name of the SSL function that generated the error. I expect it's obvious most of the time. Remove several unnecessary INCREFs in the module's constructor call. PyDict_SetItem() and friends do the INCREF for you.

Fix two memory leaks in socket.ssl(). XXX [1] These changes aren't tested very thoroughly, because regrtest doesn't do any SSL tests. I've done some trivial tests on my own, but don't really know how to use the key and cert files. In one case, an SSL-level error causes Python to dump core. I'll get the fixed in the next round of changes. XXX [2] The checkin removes the x_attr member of the SSLObject struct. I'm not sure if this is kosher for backwards compatibility at the binary level. Perhaps its safer to keep the member but keep it assigned to NULL. And the leaks? newSSLObject() called PyDict_New(), stored the result in x_attr without checking it, and later stored NULL in x_attr without doing anything to the dict. So the dict always leaks. There is no further reference to x_attr, so I just removed it completely. The error cases in newSSLObject() passed the return value of PyString_FromString() directly to PyErr_SetObject(). PyErr_SetObject() expects a borrowed reference, so the string leaked.

Fix a bunch of warnings reported by Skip. To whoever who changed a bunch of (PyCFunction) casts to (PyNoArgsFunction) in PyMethodDef initializers: don't do that. The cast is to shut the compiler up. The compiler wants the function pointer initializer to be a PyCFunction.

Expose three OpenSSL API calls for dealing with the PRNG. Quoth the OpenSSL RAND_add man page: OpenSSL makes sure that the PRNG state is unique for each thread. On systems that provide /dev/urandom, the randomness device is used to seed the PRNG transparently. However, on all other systems, the application is responsible for seeding the PRNG by calling RAND_add(), RAND_egd(3) or RAND_load_file(3). I decided to expose RAND_add() because it's general and RAND_egd() because it's a useful special case. RAND_load_file() didn't seem to offer much over RAND_add(), so I skipped it. Also supplied RAND_status() which returns true if the PRNG is seeded and false if not.

DL_EXPORT(void)
Create a new section of pyport.h to hold all external function declarations for systems that are missing those declarations from system include files. Start by moving a pointy-haired ones from their previous locations to the new section. (The gethostname() one, for instance, breaks on several systems, because some define it as (char *, size_t) and some as (char *, int).) I purposely decided not to include the summary of used #defines like Tim did in the first section of pyport.h. In my opinion, the number of #defines likedly to be used by this section would make such an overview unwieldy. I would suggest documenting the non-obvious ones, though.

Made SocketType and socket the same thing: a subclassable type whose constructor acts just like socket() before. All three arguments have a sensible default now; socket() is equivalent to socket(AF_INET, SOCK_STREAM). One minor issue: the socket() function and the SocketType had different doc strings; socket.__doc__ gave the signature, SocketType.__doc__ gave the methods. I've merged these for now, but maybe the list of methods is no longer necessary since it can easily be recovered through socket.__dict__.keys(). The problem with keeping it is that the total doc string is a bit long (34 lines -- it scrolls of a standard tty screen). Another general issue with the socket module is that it's a big mess. There's pages and pages of random platform #ifdefs, and the naming conventions are totally wrong: it uses Py prefixes and CapWords for static functions. That's a cleanup for another day... (Also I think the big starting comment that summarizes the API can go -- it's a repeat of the docstring.)

SF Patch #103185, by jlt63: Some more standard modules cleanup for Cygwin
2001-01-22 15:29:14 +00:00
#ifdef USE_SSL
Lots of code reorganization with a few small API changes. Change all the local names that start with SSL to start with PySSL. The OpenSSL library defines lots of calls that start with "SSL_". The calls for Python's SSL objects also started with "SSL_". This choice made it really confusing to figure out which calls were to the library and which calls were local to the file. Add PySSL_SetError() that sets an exception based on the information from SSL_get_error(). This function will eventually replace all the calls that set it with an error message that is based on the name of the call that failed rather than the reason it failed. (Example: If SSL_connect() failed it used to report "SSL_connect error" now it will offer a specific message about why SSL_connect failed.) XXX It might be helpful to augment the error message generated below with the name of the SSL function that generated the error. I expect it's obvious most of the time. Remove several unnecessary INCREFs in the module's constructor call. PyDict_SetItem() and friends do the INCREF for you.

Apply two changes, systematically: (1) Use PyErr_NewException("module.class", NULL, NULL) to create the exception object. (2) Remove all calls to Py_FatalError(); instead, return or ignore the errors -- the import code now checks PyErr_Occurred() after calling a module's init function, so it's no longer a fatal error for the initialization to fail. Also did some small cleanups, e.g. removed unnecessary test for "already initialized" from initfpectl(), and unified initposix()/initnt(). I haven't checked this very thoroughly, so while the changes are pretty trivial -- beware of untested code!

Patch #401196: IPv6 extensions to the socket module. New functions getnameinfo, getaddrinfo. New exceptions socket.gaierror, socket.herror. Various new constants, in particular AF_INET6 and error codes and parameters for getaddrinfo. AF_INET6 support in setipaddr, makesockaddr, getsockaddr, getsockaddrlen, gethost_common, PySocket_gethostbyaddr.

/* Initialize gethostbyname lock */
Clean up pass for the previous patches. - Use HAVE_GETHOSTBYNAME_R_6_ARG instead of testing for Linux and glibc2. - If gethostbyname takes 3 args, undefine HAVE_GETHOSTBYNAME_R -- don't know what code should be used. - New symbol USE_GETHOSTBYNAME_LOCK defined iff the lock should be used. - Modify the gethostbyaddr() code to also hold on to the lock until after it is safe to release, overlapping with the Python lock. (Note: I think that it could in theory be possible that Python code executed while gethostbyname_lock is held could attempt to reacquire the lock -- e.g. in a signal handler or destructor. I will simply say "don't do that then.")

Thanks to Chris Herborth, the thread primitives now have proper Py* names in the source code (they already had those for the linker, through some smart macros; but the source still had the old, un-Py names).
