Patrick,
I have attachment uploads set to use group subdirectories of an
"uploads" directory. The userid/groupid of upload subdirectories created
by PHP (PmWiki) before the upgrade are henrik/henrik (ie the
userid/groupid of the master account). The userid/groupid of directories
created by PHP after the upgrade are 99/99 identified in the phpinfo.php
listing as nobody(99)/nobody(99).
I believe this constitutes proof, or at least evidence, that the
userid/groupid of PHP had changed, as you suggested.
In the meantime I have changed the permissions of all PmWiki write
directories in all my sites (some 80 subdirectories) to 777, which seems
to resolve the problems caused by the change.
I've asked the company to change the PHP userid/groupid back to the
master account values, as the change has also negatively effected other
applications. We'll see what they do.
BTW after I pointed out to webserve.ca that the PHP 5.2.1 had been
rolled back to 5.0.5, they promptly (within 4 hours) re-installed 5.2.1.
They must have made a mistake. They're like that. Thanks for the heads up.
Best,
- Henrik

All was going well until my hosting company upgraded my shared hosting
server to PHP 5.2.1. A good thing to upgrade, but all of a sudden all my
wikis broke, with "unable to obtain .flock file" (among other things).
After several days of (in the end) pointless dialog with my host service
company (webserve.ca), I ended up having to change rights on all wiki.d
and uploads directories from 755 to 777. I presume this means that
whereas PHP previously had owner rights, it now has none, and therefore
needs public access to write directories.
Does anyone know where to look for a configuration change on my host
that would make this happen?
I'm not sure that a PHP configuration change alone can explain the
entire issue. It would help to know the ownerships for files created
before the change versus the ownerships of the files being created
after the change -- I suspect that the userid also changed in
the process somewhere.
Were the directories really 755 permissions (as opposed to
775) before the upgrade occurred? If the directories were 755
and the files created by PmWiki were 644, that would imply that
previous PmWiki (and PHP) were running under your userid instead
of the "nobody" or "www" user.
Anyway, based on your description it looks like the PHP user may
have changed somehow... but it's still odd.
If useful, you can see the php
configuration at dufferinpark.ca/phpinfo.php.
Actually, that page says you're running 5.0.5, not 5.2.1 .
My web host BTW proffered the rather desperate theory that someone had
hacked my account and systematically altered permissions on all my wiki
directories (there are at least a couple of dozen). This is not true. I
checked<grin>.
All of this gets down to a question of file and directory ownerships --
which is why it's important to know the before/after to be able
to say what might have happened or changed.
