SID-01918: File permissions in configuration - a bug?

Status:	Answered	TWiki version:	6.0.0	Perl version:	5.18.1
Category:	CategoryInstallation	Server OS:	opensuse 13.1	Last update:	11 years ago

Struggling to get my new twiki 6.0 install working, I've come across what is likely a bug in the configuration file or twiki operation.

Under "Store settings" it asks for dirPermissions and filePermission which are supposed to be in octal, the usual 0755 and 0644 in linux. Strangely, when the configuration is saved, they are stored as decimal values (e.g., 01363 for 0755, which is incorrect). It seems that everytime configure is run, the octal value is converted to decimal, which is then read as octal and converted to another decimal, etc.

In short, every time configure is run these have to be reset to the correct decimal values 493 (for 0755 octal) and 420 (for 0644 octal).

These values are stored in the /twiki/lib/LocalSite.cfg file, where one can set the values 493 and 420 manually for correct operation. It seems that twiki wants to have these permissions stored in their decimal values.

I was not able to find this discussion/bug report in all my google searches.

Thanks for the nice software!

(What prompted the upgrade to twiki 6,0 was an upgrade of my linux system to opensuse 13.1.)

Discussion and Answer

We got a report and fix: TWikibug:Item7517 configure breaks {RCS}{filePermission} under Perl v5.18.2. This is caused by a Perl bug. The fix works around the bug.

Please apply the patch, then run configure and set {RCS}{dirPermission} to 0755, and {RCS}{filePermission} to 0644.
