ziplib

Greetings,

as upgrading systems, and especially everything involving php on
linux is always very painful (at least in my experience ;-) I
always postpone that as long as possible. But now is the time :-)

I have (had ;-) a phpwiki 1.3.12p3 running on SuSE Linux 10.2,
and moved that installation to a new SuSE 10.1 (latest patches).
After fiddling with the usual PHP stuff (register_long_arrays and
stuff), I came to a point where every page request would give a
> Fatal PhpWiki Error
> Unsupported ZIP header type: xÚ­T

I tracked down that message and found it in ziplib (line 452 in
my version). Now the fun thing is, I just commented the
> ExitWiki(sprintf("Unsupported ZIP header type: %s ", $magic));
out, and now it seems to run.

My PHP skills are a bit rusty, so I was unable to find out just
what we're trying to zip or unzip here...

I tried the ziplib versions from the previous phpwikis I still have
on disk, 1.3.11rc3 and 1.3.10, but they produced the same result.

Questions:

Did I do something harmful by commenting it out ?

Do you have any idea what is being zipped or unzipped on every
page request ?

Any idea how to fix this ?

Is it maybe related to the newer linux having different compression
algorithms somehwere, or the newer apache2 httpd ?

Cheers!
Tom.
