After one succesfull download of a tour bundle, later ones fail

[hannolans]

When I create a tour I can succesfully download a tour bundle. After the first time I still get a progress bar but then at the end 'An error occurred'.
Probably because the file name already exists?

Tested and this doesn't happen when you first delete the bundle attachment (part of a tour node) manually by editing the node before creating a new bundle.

Debugged further and it is caused by this if statement:

// If we have a stale tmp file delete it
if (file_exists($path)) {
    unlink($path);
}

If you disable unlink($path), it doesn't fail:

// If we have a stale tmp file delete it
if (file_exists($path)) {
//    unlink($path);
}

Could this be a permission issue on the file that was originally created?

ah – I ran into this problem as well.

specific error message (this is the first bundle after changing the name of the node, so at least I get the bundle):

Ambrosiani, are you running php 5.3? these errors are typical when running on php 5.2

[Ambrosiani]

hi, I'm running php 5.4.4 (on MAMP 2.1.1). Any specific php setting I should try out?

[karnold]

try downgrading to php 5.3

[Ambrosiani]

OK, I'll try that and get back to you!

[Ambrosiani]

hmm, php 5.3 seems to cause a lot of conflicts with the underlying modules. I'll keep experimenting a bit and just disregard this problem at the moment.

edit: never mind, cacheing was the problem. With php 5.3.14 bundle exporting works without throwing error messages.
