svn: OPTIONS of '...' could not connect to server

I had this weird problem today with SVN. I was able to browse it using the web browser. I was able to update from SVN, but when I was trying to commit something, I got an error:

svn: OPTIONS of 'http://....': could not connect to server.

This looked weird. Finally I disabled my wifi link and restored a wired ethernet connection to my LAN. After this, the commit went fine without any issues.

I am still wondering what was the real cause behind this problem.

Building ssl for Python 2.5.4 on Windows

I went through the instructions from this blog post:

In the end while building ssl, I faced a one last problem:

C:\MinGW\bin\gcc.exe -mno-cygwin -shared -s build\temp.win32-2.5\Release\ssl\_ssl2.o build\temp.win32-2.5\Release\ssl\_ssl2.def "-LC:\Program Files (x86)\GnuWin32\lib" -LC:\Python25\libs -LC:\Python25\PCBuild -lssl -lcrypto -lwsock32 -lgdi32 -lgw32c -lole32 -luuid -lpython25 -lmsvcr71 -o build\lib.win32-2.5\ssl\_ssl2.pyd -static
build\temp.win32-2.5\Release\ssl\_ssl2.o:_ssl2.c:(.text+0x1724): undefined reference to `_wassert'
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1

As you can notice, the linker is complaining about _wassert.

After some googling, I ended up opening the ssl\_ssl.c file in the ssl source package and added the following lines at the beginning (after Python.h include).

#ifdef __MINGW32__
#undef assert
#define assert(expr) ((void)0)
#endif

The build went smoothly after that.
