I found a problem in libpq.dll when trying to send large SQL
|
|
statements to postgres 7.1.x on FreeBSD 4.3 from Windows 2000. The
|
|
same SQL worked fine when sent from FreeBSD. At first I thought it
|
|
was something to do with an 8k limit on text fields but it's just low
|
|
level socket code trying to deal with large packets that breaks on
|
|
Win32.
|
|
|
|
It looks like recv on Win32 returns ENOENT instead of EAGAIN for some
|
|
reason. I avoid C as much as possible and low level socket stuff so
|
|
this is all new to me. I hacked libpq\fe-misc.c to handle ENOENT the
|
|
same way it handles EAGAIN and everything works now. I got the clue
|
|
from searching deja.com for "ENOENT EAGAIN recv". The first article
|
|
describes a similar problem.
|
|
|
|
I don't know if my code is the correct fix. Who should I send it to?
|
|
|
|
Thanks,
|
|
Jeff

I found that sending more than 16k of data in a SQL statement caused a
|
|
problem. I was using PyGreSQL but narrowed the error down to
|
|
"\postgresql-7.1.2\src\interfaces\libpq\fe-misc.c" pqReadData() and
|
|
pqFlush(). After some poking around, it looked like recv was setting
|
|
errno to ENOENT for some reason. I figured out why today. Win32
|
|
sockets don't set errno at all. ENOENT was just left in errno from
|
|
some earlier call.
|
|
|
|
This article describes the problem and work around.

other code by blindly doing:

|

|

Does anyone that knows this code want to take a crack at it?

Can you try this patch and let me know if it helps? It is a different
|
|
approach. This was the only place I saw errno checked for a
|
|
non-predefined value.
|
|
|
|
One other solution may be to use the #define only in the libpq C files
|
|
that need it. What really stinks is that the errno define is only
|
|
useful for socket errno settings.
|
|
|
|
I do see a use in fe-connect.c:
|
|
|
|
#ifndef WIN32
|
|
if (errno == EINPROGRESS || errno == 0)
|
|
#else
|
|
if (WSAGetLastError() == WSAEINPROGRESS)
|
|
#endif
|
|
|
|
I hate to litter this through the whole source. I wonder if we have to
|
|
bracket the errno checkes with #define/#undef. Can you try that with
|
|
the fix described on the web page. The above would convert to:
|
|
|
|
#ifdef WIN32
|
|
#define errno WSAGetLastError
|
|
#endif
|
|
if (errno == EINPROGRESS || errno == 0)
|
|
#ifdef WIN32
|
|
#undef errno
|
|
#endif
|
|
|
|
Maybe make these into their own macros somehow.

There are already a few (wrong) attempts to cover this situation in
|
|
fe-connect.c, but it looks like a bunch of #ifdef's are needed.

Probably rather
|
|
|
|
#ifndef WIN32
|
|
normal code;
|
|
#else
|
|
windows code;

#endif

Comes up fine for me (maybe you need to turn off Javascript?)
|
|
|
|
However, the advice on it seems to be written by someone who does not
|
|
know the difference between a variable and a function :-(. Read with
|
|
a large grain of salt.
|
|
|
|
We already have a couple of #ifdef'd usages of WSAGetLastError() in
|
|
libpq, but it's quite unclear which other references to errno might
|
|
need to be changed. A blanket replacement of errno would certainly
|
|
break things.

Comes up fine for me (maybe you need to turn off Javascript?)
|
|
|
|
However, the advice on it seems to be written by someone who does not
|
|
know the difference between a variable and a function :-(. Read with
|
|
a large grain of salt.
|
|
|
|
We already have a couple of #ifdef'd usages of WSAGetLastError() in
|
|
libpq, but it's quite unclear which other references to errno might
|
|
need to be changed. A blanket replacement of errno would certainly
|
|
break things.

That's why I recommended brackets of #define/#undef around tests of
|
|
socket errno's.

Setting errno = 0 doesn't help, the error handling code is entered
|
|
when recv returns -1, then even if errno == 0, it'll bomb out.

Even when I was a C programmer I never did much more than simple
|
|
defines with the pre-compiler so I'll leave this to those that know
|
|
how :)
|
|
|
|
As Tom Lane points out in another post, the "define errno
|
|
WSAGetLastError" seems to confuse a variable with a function. I was
|
|
surprised that such a thing could work. I'm happy to hear that it
|
|
doesn't.
|
|
|
|
What about something like this:
|
|
|
|
#ifdef WIN32
|
|
#define s_errno WSAGetLastError()
|
|
#else
|
|
#define s_errno errno
|
|
#endif
|
|
|
|
/* for socket functions, check s_errno */
|
|
if (s_errno == EINPROGRESS || s_errno == 0)
|
|
...
|
|
|
|
/* for non-socket functions, check errno as usual */
|
|
if (errno == ENOENT)
|
|
...
|
|
|
|
|
|
Then replace only errno with s_errno when it is used with socket code.
|
|
I'm not sure if strerror would work with all the errors returned by
|
|
WSAGetLastError(). The Win32 SDK says to use FormatMessage(a ton of
|
|
stuff here).

I have done exactly that. I assume fcntl(), ioctl(), select() use errno
|
|
even if used on a socket, while getsockopt(), setsockopt(), socket(),
|
|
connect(), getsockname(), send(), recv() use WSAGetLastError. Is this
|
|
list correct?
|
|
|
|
The patch is attached. Please let me know so I can finalize it and
|
|
apply it.

Couple of changes required to compile on Win32:
|
|
|
|
Change:
|
|
#define sockerrno WSAGetLastError
|
|
To:
|
|
#define sockerrno WSAGetLastError()
|
|
|
|
|
|
This has to go back into fe-connect.c, EINPROGRESS isn't defined in
|
|
Win32 for some reason..
|
|
#ifndef WIN32
|
|
if (errno == EINPROGRESS || errno == 0)
|
|
#else
|
|
if (WSAGetLastError() == WSAEINPROGRESS)
|
|
#endif
|
|
|
|
|
|
|
|
I tested it out but I'm getting this error when sending a large SQL
|
|
statement (>16k).

I modified the patch to use WSABASEERR rather than 10000.
|
|
|
|
Do your includes define EAGAIN and stuff like that? Whare are those
|
|
values? If they are the same as WSAEAGAIN, then my patch should work.

EAGAIN is defined as 11 so the sockerror - 1000 solution isn't going

|
|
No, that list is not correct.
|
|
|
|
1) select() can *only* be used on a socket in Windows, and it puts its
|
|
error info in WSAGetLastError().
|
|
|
|
2) ioctl() should *not* be used on sockets. Instead, ioctlsocket()
|
|
shuold be used. ioctlsocket() puts its error info in WSAGetLastError().
|
|
(http://msdn.microsoft.com/library/psdk/winsock/ovrvw3_98mq.htm). (loads
|
|
fine in my Netscape, doesn't look all that good, but definitly readable)
|
|
|
|
3) fcntl() should *not* be used on sockets. ioctlsocket() again.
|
|
|
|
Generaelly, all functions dealing with sockets use WSAGetLastError().
|
|
And sockets and file descriptors are *not* necessarily interchangable on
|
|
Win32.
|
|
|
|
|
|
Note - this is Win32, *not* cygwin. Cygwin maps to errno, AFAIK.
