is larger than FD_SETSIZE.
This can only be acheived with ulimit -n SOME_NUMBER_BIGGER_THAN_FD_SETSIZE
which is typically only available to root. Since this wouldn't normally
be run in a test (ie, run as root), it doesn't seem too worthwhile to
add a normal test. The bug report has one version of a test. I've
written another. Not sure what the best thing to do is.
Do the check before calling internal_select() because we can't set
an error in between Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS.
This seemed the clearest solution, ie handle before calling internal_select()
rather than inside. Plus there is at least one place outside
of internal_select() that needed to be handled.
Will backport.
In C++, it's an error to pass a string literal to a char* function
without a const_cast(). Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.
I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc. Predictably, there were a large set of functions that
needed to be fixed as a result of these changes. The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].
One cast was required as a result of the changes: A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.
memset() wrote one past the end of the buffer, which was likely to be unused padding or a yet-to-be-initialized local variable. This routine is already tested by test_socket.
Added setbdaddr and makebdaddr.
Extended makesockaddr to understand Bluetooth addresses.
Changed getsockaddr to expect the Bluetooth addresses as a string,
not a six element tuple.
Reformatted some of the Bluetooth code to be more consistent with PEP 7.
[ 728330 ] Don't define _SGAPI on IRIX
The Right Thing would be nice, for now this'll do. At least it isn't
going to break anything *other* than IRIX...
- return the full size of the sockaddr_un structure, without which
bind() fails with EINVAL;
- set test_socketserver to use a socket name that meets the form
required by the underlying implementation;
- don't bother exercising the forking AF_UNIX tests on EMX - its
fork() can't handle the stress.
I don't think the fix here is very good, but I'm not sure what would
be better. In particular, we should not be defining _SGIAPI, but lots
of things break if we remove it.

Added a new exception, socket.timeout so that timeouts can be differentiated
from other socket exceptions.
Docs, more tests, and newsitem to follow.
- The socket module now provides the functions inet_pton and inet_ntop
for converting between string and packed representation of IP addresses.
See SF patch #658327.
This still needs a bit of work in the doc area, because it is not
available on all platforms (especially not on Windows).
Rather than trying to second-guess the various error returns
of a second connect(), use select() to determine whether the
socket becomes writable (which means connected).
inet_aton() rather than inet_addr() -- the latter is obsolete because
it has a problem: "255.255.255.255" is a valid address but
indistinguishable from an error.
(I'm not sure if inet_aton() exists everywhere -- in case it doesn't,
I've left the old code in with an #ifdef.)
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.
Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.
On HPUX, Solaris, Tru64 (Dec UNIX), and IRIX (I think),
O_NONBLOCK is the POSIX version of non-blocking I/O
which is what we want.
On Linux and FreeBSD (at least), O_NONBLOCK and O_NDELAY are the same.
So this change should have no negative effect on those platforms.
Tested on Linux, Solaris, HPUX.
Thanks to Anders Qvist for diagnosing this problem.
value; others were inconsistent in what to name the argument or return
value; a few module-global functions had "socket." in front of their
name, against convention.
WSAEWOULDBLOCK, the second connect() attempt appears to yield WSAEISCONN
on Win98 but WSAEINVAL on Win2K. So accept either as meaning "yawn,
fine". This allows test_socket to succeed on my Win2K box (which it
already did on my Win98SE box).
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure. Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers. (In
fact, we expect that the compilers are all fixed eight years later.)
I'm leaving staticforward and statichere defined in object.h as
static. This is only for backwards compatibility with C extensions
that might still use it.
XXX I haven't updated the documentation.
that retries the connect() call in timeout mode so it can be shared
between connect() and connect_ex(), and needs only a single #ifdef.
The test for this was doing funky stuff I don't approve of,
so I removed it in favor of a simpler test. This allowed me
to implement a simpler, "purer" form of the timeout retry code.
Hopefully that's enough (if you want to be fancy, use non-blocking
mode and decode the errors yourself, like before).
- setblocking(0) and settimeout(0) are now equivalent, and ditto for
setblocking(1) and settimeout(None).
- Don't raise an exception from internal_select(); let the final call
report the error (this means you will get an EAGAIN error instead of
an ETIMEDOUT error -- I don't care).
- Move the select to inside the Py_{BEGIN,END}_ALLOW_THREADS brackets,
so other theads can run (this was a bug in the original code).
- Redid the retry logic in connect() and connect_ex() to avoid masking
errors. This probably doesn't work for Windows yet; I'll fix that
next. It may also fail on other platforms, depending on what
retrying a connect does; I need help with this.
- Get rid of the retry logic in accept(). I don't think it was needed
at all. But I may be wrong.
settimeout(). Already, settimeout() canceled non-blocking mode; now,
setblocking() also cancels the timeout. This is easier to document.
(XXX should settimeout(0) be an alias for setblocking(0)? They seem
to have roughly the same effect. Also, I'm not sure that the code in
connect() and accept() is correct in all cases. We'll sort this out
soon enough.)
