Item3640: Configure extensions installer does not install anything

And it failed. It turns out that no matter which version. 4.1.1. Patch04x01 without my changes. 2 different test machines.

Installing for example VotePlugin gives this run

Error: Failed to move file 'bin/vote' to bin/vote: No such file or directory
VotePlugin_installer.pl ran without errors

Installation finished.

Looks fine at first glance. BUT NOTHING IS INSTALLED.

It is not just the strange error at the end. No file at all shows up in the TWiki tree. And I cannot find them anywhere.

Update. It turns out it works on my machine that runs Centos 4.4 and TWiki 4.1.1 non SVN checkout.

I think it is related to CPAN dependencies. I have the feeling the OS zip code is the problem.

OK. In the above example the bin/vote is missing so things do not work right.

And on my Patch04x01 branch and different machine I get this

So even if the Extension installer is now supposed to work without Archive::Tar is does not.

-- TWiki:Main.KennethLavrsen - 15 Feb 2007

Or is it really Archive::Tar that fails? I am not sure the EXTEND.pm line 149 seems to just report an earlier error and it is not certain that the error reported is the error that triggers the script to stop.

-- TWiki:Main.KennethLavrsen - 15 Feb 2007

I think I have a fix now for the bin/vote error. Still searching for why it fails on the installation without Archive::Tar

-- TWiki:Main.KennethLavrsen - 15 Feb 2007

I know why now. Making a fix

-- TWiki:Main.KennethLavrsen - 15 Feb 2007

There were two errors.

• After doing some file copying a die checked on $@. But $@ is only set after an eval. So the script died for no reason when en eval of Archive::Tar had failed. The command line unzip worked OK. It just died because of the wrong check. I replaced it with some simple dies following the already existing error messages.
• The path created for files in bin were relative. All others absolute. The code seems to expect absolute. Fixed this by also making bin dir path absolute.

I have seen additional errors with other plugins but will open seperate bug item for that.

-- TWiki:Main.KennethLavrsen - 16 Feb 2007

Closed with release of 4.1.2
