Bug 29015 – Portage does not deal well when a directory has the same name as a file that is being installed

• Status: RESOLVED DUPLICATE of bug 23851
• Product: Portage Development

[Description A. Craig West 2003-09-17 16:03:57 UTC]

When a directory exists which has the same name as a normal file that portage is
trying to install, the file is not installed properly. For example, on my system
disk corruption caused /usr/include/security/pam_appl.h and
/usr/include/security/pam_modules.h to be replaced with directories. When I
re-merged pam these files were not fixed, so anything which tried to include
these files failed building.

Reproducible: Always
Steps to Reproduce:
1.Replace file installed by an ebuild with a directory
2.emerge the ebuild
3.

Actual Results:  
the bogus directory is still in place

Expected Results:  
either the directory should be replaced with the file, or an error should be
produced. I'm not picky...

This will be up for testing in portage-2.0.50_pre9.

unlink doesn't like directories and we basically ignore the exception:

try:
	os.unlink(obj)
	print "<<<       ","sym",obj
except (OSError,IOError),e:
	print "!!!       ","sym",obj
	#immutable?
	pass
