Question

Hey all. Experiencing a minor problem with rcs in my twiki. From the revision history toolbar on the bottom of the twiki -- comparing two versions of a file works fine, I see the new changes in green, old in red, etc. However, if I click on a particular revision -- say, version 1.12 of a document -- the page that comes back is blank.

Any ideas? It looks like rcs is working ok, as I can diff versions fine, and get a complete history of changes ok as well. Looked at the .txt,v files and saw that the revisions are collecting just fine.

A second small prob I've noticed is revision history on files. Perhaps this is by design, but, if I upload a few versions of a file, and then view the each version of the file on the file-manage page, all the versions are identical.

thx!

Lyle

Answer

Ok, I answered my own question. The problem was in the RcsWrap.pm module.

Line 364 if( $tmpfile and -e $tmpfile ) {

The problem was that the $tmpfile wasn't being created. So simply adding a check to make sure that it exists solved the problem.

Thanks for the update, Lyle. Is your solution a fix for your first or your second problem?

Hey Martin, sorry, should have been more clear; this is a fix for the first problem (selecting versions from the revision history toolbar returning empty pages ).

Same Problem, Solution not Obvious

I am having the same issue as Lyle, but when I tried to apply his fix, I couldn't find the line he mentioned in my RcsWrap.pm, either at the line number, or by searching for the expression. My environment is a bit different, but I'm using the same Twiki release. The problem is identical: I can see revision history, but when I click on the r.1.x link in a page, I just get a blank page with the footer and Edit and Attach crossed out.

Environment

TWiki version:	TWikiRelease01Sep2004
TWiki plugins:	DefaultPlugin, TwikiDrawPlugin, TablePlugin
Server OS:	Win 2000 Advanced on VMWare ESX
Web server:	Apache 1.3
Perl version:	5.6.1, build 638 (ActiveState)
Client OS:	Win 2000
Web Browser:	IE6

I have configured Twiki according to the WindowsInstallCookbook, and added domain authentication per the WindowsInstallModNTLM, as well as applying the ntlm-username patch from LoginNameAndNtlm.

Any ideas would be appreciated.

Max, I just checked RcsWrap.pm; its in the getRevision() method of that module. Please doublecheck at let me know? If you like, email me your copy of RcsWrap to
