I can't add any attachment to my wiki. When I select file using "Browse"
button and click "Upload Attachment", then `ikiwiki.cgi` file displays
the error message like below:
Błąd: failed to get filehandle
> Can you do some debugging? If you edit attachment.pm line 136, to print
> out what it did get, and show me what that yields, maybe I can figure
> this out.
error("failed to get filehandle ($fh)");
>> Sure. I've done the change and it seems that $fh variable is undefined:
>> Use of uninitialized value in concatenation (.) or string at /usr/share/perl5/IkiWiki/Plugin/attachment.pm line 135.
>> failed to get filehandle ()
> Also, what web server and version of perl is this? --[[Joey]]
>> It's Apache2 2.2.8-1ubuntu0.3 and Perl 5.8.8-12 from Ubuntu Hardy. --[[Paweł|ptecza]]
>>> Hmm, is your CGI.pm perhaps creating the attachment temp file, but
>>> not providing an open filehandle to it via the `upload` method?
>>> Change the debugging line to this: --[[Joey]]
error("failed to get filehandle:$fh ; file:$filename ; is ref:".ref($q->param('attachment')));
>>>> Now my Ikiwiki returns:
>>>> failed to get filehandle: ; file:sandbox/test.txt ; is ref:
>>>> Is it helpful for you? --[[Paweł|ptecza]]
>>>>> Yes, this suggests that CGI.pm's `upload` function is not working,
>>>>> but that it *is* returning a filehandle pointing at the attachment
>>>>> using the old method. Hmm, so I'll bet you have a CGI.pm version
>>>>> older than 2.47. Can you find your system's CGI.pm and grep for
>>>>> "VERSION" in it to determine the version? I checked debian stable.
>>>>> and its perl 5.8.8 has version 3.15, so is not affected, I think.
>>>>>> I have CGI.pm 3.15 too:
>>>>>> $ grep VERSION= /usr/share/perl/5.8.8/CGI.pm
>>>>>> $CGI::VERSION='3.15';

>>>>>>>> If so, then it causes "Internal Server Error" for me:

>>>>>>>>>> Thanks for the fix, Joey! Now CGI doesn't fails, but still no success with attaching file:

The same message I can see in the Apache log file. There is also
following warning:
Use of uninitialized value in length at /usr/share/perl5/IkiWiki/Plugin/attachment.pm line 36.
> This is unrelated, I've fixed the warning message. --[[Joey]]
Is it Ikiwiki bug or my attachment plugin is misconfigured? --[[Paweł|ptecza]]
> Joey, please fix the colon in page name of my report. [...]
>> Moved to [[colon:problem]] --[[Joey]]
