Kevin Chen added the comment:
This is essentially the way things were done in version 2.5.4 of Python. The
unlink() always succeeded, because the created .pyc file permission is always
set to 0666 in the fd=open() function. This means the .pyc will never be
created as read-only, and as long as they are never set to read-only manually
by the user, everything will be okay.
You might say this will be a problem if someone accidentally set the it to
read-only. Well we have been using Python 2.5 for many years, and we have
managed quite well, so it is not really going to be a big issue, and can be
fixed in the future.
Whereas at the moment we have a PROBLEM!! With the current state of the Python
2.6, 2.7 and 3.2 interpreters, many Windows users cannot even think about
upgrade from Python 2.5 because source control tools like Perforce will set all
.py files to read-only, and so ALL created .pyc files will become read-only
every time you run Python. I cannot stress how much pain this causes. PLEASE
MAKE IT 2.5 EQUIVALENT ASAP! THANK YOU!!
even just this will do the trick:
-------------------------------------
fd = open(filename, O_EXCL|O_CREAT|O_WRONLY|O_TRUNC
#ifdef O_BINARY
|O_BINARY /* necessary for Windows */
#endif
#ifdef __VMS
, mode, "ctxt=bin", "shr=nil"
#elif defined(MS_WINDOWS)
, 0666
#else
, mode
#endif
);
-----------------------------------
And a side note, for the VC8 build for PC, the file random.c was left out from
the visual studio project file for pythoncore project. It gives these errors
when I try recompile:
Error 2 error LNK2019: unresolved external symbol __PyRandom_Init
referenced in function _Py_Main main.obj
Error 3 error LNK2001: unresolved external symbol __PyRandom_Init
pythonrun.obj
Error 4 error LNK2019: unresolved external symbol __PyOS_URandom
referenced in function _posix_urandom posixmodule.obj
This is my first time using bug tracker, so please point me to the appropriate
place to put this. Thank you.
