I'm sorry to report that your patch does not fix the following rebase
problem:
http://sourceforge.net/tracker/?func=detail&atid=305470&aid=491107&group_id=5470
Specifically, I'm getting the following:
$ make
...
building 'gdbm' extension
gcc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DUSE_DL_IMPORT -I. -I/tmp/python-2.2.1-1/./Include -I/usr/local/include -IInclude/ -c /tmp/python-2.2.1-1/Modules/gdbmmodule.c -o build/temp.cygwin-1.3.13-i686-2.2/gdbmmodule.o
C:\cygwin\tmp\python-2.2.1-1\build\python.exe: *** unable to remap C:\cygwin\bin\cygcrypto.dll to same address as parent -- 0x420000
8 [main] python 1548 sync_with_child: child 2772(0x100) died before initialization with status code 0x1
9652 [main] python 1548 sync_with_child: *** child state child loading dlls
error: Resource temporarily unavailable
make: *** [sharedmods] Error 1
If you wish, you can reproduce the problem yourself with the following:
$ wget -nd http://www.python.org/ftp/python/2.2.1/Python-2.2.1.tgz
$ tar -xzf Python-2.2.1.tgz
$ cd Python-2.2.1
$ configure
$ make
The following (simpler) test case also fails:
$ cat test.py
import os
import _socket
pid = os.fork()
$ ./python test.py
C:\cygwin\tmp\python-2.2.1-1\build\python.exe: *** unable to remap C:\cygwin\bin\cygssl.dll to same address as parent -- 0x1A2F0000
7 [main] python 2456 sync_with_child: child 2968(0x120) died before initialization with status code 0x1
2838 [main] python 2456 sync_with_child: *** child state child loading dlls
Traceback (most recent call last):
File "test.py", line 4, in ?
pid = os.fork()
OSError: [Errno 11] Resource temporarily unavailable
Please let me know if I can help you in any way. I truly want you to
succeed with your rebase alternative.
Thanks,
Jason
