Hi, Glad to see my patch works on AIX, not so glad it fails with TRU64
UNIX
Did you test with the same script/environment you wrote on Jan 30?
Did you try to log the value of path after each VCWD_REALPATH.
AFAICS, the whole bug comes from realpath doing nasty things when path
is NULL hence the strcopy I added.
Feel free to email directly. I'm not a PHP developper (I'd love the
help of one on this one) but I want to get rid of this bug.
Regards
Olivier

Patch makes no difference with Tru64 UNIX 5.1A and PHP 4.3.2.

I tested that patch.
Works just fine in AIX 4.3.1 php 4.3.2

after 2 strggling, I came with the following path on
safe_mode.c against 4.3.2RC4.
Not sure it's the right thing to do.
could someone have a look?

this works on Unixware 713

I have made tons of research on this since yesterday.
It appears that realpath (at least on UW 713) set path to NULLL,
returns NULL with errno=2 in case of a non existing file on line 86 in
safe_mode.c then function proceeds to line 116 with a NULL path, all
functions fail and the file cannot be created.
Hope this help to create a patch (I'm trying to but don't know the code
enough too) Please someone help.

The bug is still there with php-4.3.2RC4 as an apache 1.3.27 module.
This is on Unixware 7.
with safe_mode=Off, file creation succeeds,
with safe_mode=On, file creattion fails with "failed to open stream: no
such file or directory ..."
I've tried setting the dir 777, make it owned by apache UID.. Nothing
worked.
A truss of the apache server showed that the last syscall before failed
was a pathconf(filename,...) returning ENOENT
File didn't exist so it's normal.
Please help
