SID-01010: Viewfile modifies downloaded filename

Status:	Answered	TWiki version:	5.0.0	Perl version:	5.10.0
Category:	CategoryAttachments	Server OS:	SuSE (SLES) 11 SP1, kernel 2.6.32	Last update:	14 years ago

The viewfile script appears to be changing (legal) attachment filenames on download. For example, the attachment Batch_Process_Diagrams.vsd becomes batch-process-diagrams.vsd. This is causing workflow problems when people want to modify and re-attach an attachment. We need viewfile to reference specific revisions (otherwise would use pub urls).

The two changes we have noticed are conversion to lowercase, and changing underscores to hyphens.

The correct (unmodified) filename is logged. The Content-Disposition header comes back with the modified filename eg:

Content-Disposition: inline;filename=batch-process-diagrams.vsd

Appreciate any suggestions on this. Happy to provide configure output via email.

Many thanks

Discussion and Answer

I am testing this here:

• https://twiki.org/p/pub/Support/SID-01010/Batch_Process_Diagrams.txt - using pub URL
• https://twiki.org/cgi-bin/viewfile/Support/SID-01010?filename=Batch_Process_Diagrams.txt;rev=2 - using filename parameter
• https://twiki.org/cgi-bin/viewfile/Support/SID-01010/Batch_Process_Diagrams.txt?rev=2 - using extended view path

I can confirm that this is a bug and filed TWikibug:Item6602.

In above example, the second and third link display the txt in the browser with proper filename, but when saving as a file it saves the lowercase version of the file. Using FF 3.5.

If you are a programmer I invite you to help debug and attach a patch to the bug topic.
