Adjusting the 1024 byte stdin buffer limit
Are there runtime settings that can be used to adjust the default 1024 byte stdin buffer limit or a buildtime setting in pyconfig.h? I have a need to pump this up to permit input of a large data block via stdin. Tim Jones -- http://mail.python.org/mailman/listinfo/python-list
Re: Adjusting the 1024 byte stdin buffer limit
Currently, when sending a data stream that exceeds 1024 bytes via stdin, the stream blocks at the 1024th byte. This precludes completion of the submission of the data stream. Tim -- http://mail.python.org/mailman/listinfo/python-list

Re: Adjusting the 1024 byte stdin buffer limit
Hi All, - Thanks, but it seems I may have been a bit more confused that even I thought. It turns out to be an issue with Apple's OS X pty/tty interface. Even though the mediator tool is set up to read in up to 20K of data, the pty interface blocks at 1024 bytes. When testing this under Linux, I'm fine. And, Solaris 8 weaves an even more diabolical 255 character limit :( . - Looks like I'll need to be a bit more creative than simply spawning a shell. - Tim Fredrik Lundh wrote: > "brucoder" <[EMAIL PROTECTED]> wrote: > > > Currently, when sending a data stream that exceeds 1024 bytes via > > stdin, the stream blocks at the 1024th byte.

Visual Studio 6 compile of 2.5.2 fails with missing db.h
Hi Folks, Searched the archives, but I can only find mention of db.h problems relating to Linux. I've downloaded the source for 2.5.2 and am trying to compile it in Visual Studio 6 (SP6). The error reports read: Configuration: _bsddb - Win32 Debug Compiling... _bsddb.c C:\Documents and Settings\Tim\My Documents\Python-2.5.2\Modules \_bsddb.c(90) : fatal error C1083: Cannot open include file: 'db.h': No such file or directory Error executing cl.exe. _bsddb_d.pyd - 1 error(s), 0 warning(s) Any pointers? A prerequisite that I might be missing? The source is the Python-2.5.2.tar.gz from the Python.org site. Thanks for any help, Tim -- http://mail.python.org/mailman/listinfo/python-list

Since I don't need that functionality, I now see that I can simply exclude it from my lib and exe builds. Thanks, Tim -- http://mail.python.org/mailman/listinfo/python-list
