Setting up VersionSync for small group
Nov 27^th, 2009, 9:15am

Hello everybdoy,

I'm trying to set up a team design environment using VersionSync which is delivered with IC5141.

Everything is working fine, except for the "common library":
For this lib everybody should have write permission, so that User 1 creates a design and User 2 might change it (e.g. on person does the circuit, the second does the layout and adds some dummy transisitors to the circuit). In reality only the owner (=creator) of the design can change or even add a new view to the cell (to the repository).

According the versionSync documentation I should be able to change this by setting VSFILEPERMS = 664 and VSDIRPERMS = 775 - but I see absolutely no effect when I set these variables! :-[
I also tried to set the sticky bit for the repository root and VSFILEPERMS=2775 to keep the sticky bit - this didn't work also.

Can anybody give me a hint how to solve this problem?

Thank you in advance
Markus

I should point out that VersionSync has not been supported for several years now (whilst it is still in IC5141, it was end-of-lifed - the OEM agreement under which it was delivered to Cadence from Synchronicity (now part of Dassault Systemes) came to an ened).

How and where are you setting these variables? I assume you're doing:

setenv VSFILEPERMS 664

etc before starting icfb?

Regards,

Andrew.

Hello Andrew,

thank you for your answer.

I know that VersionSync is at the end (or over) it's lifetime, we know it's drawbacks but anyway, it's sufficient for us.

I'm doing like you've written. I set the variables using "setenv" before I start "icfb" resp. before I use "gdmci" or "gdmco".

Anyway:
I have solved the problem meanwhile. I have to set "VSDIRPERMS=2775" and "VSFILEPERMS=2664". The problem was that our users belong to two different groups and the group information is only kept by VersionSync if the sticky bit is set for VSFILEPERMS, too - even if this shouldn't be necessary (as far as I understand the principles of the Linux file system...).

Regards,
Markus

Hi Markus,

BTW (me being pedantic), it's not the "sticky" bit but the "setuid" or "setgid" bit (a common mistake). The "sticky" bit is for something else altogether - usually used in /tmp to prevent others being allowed to delete files.

I didn't try anything out, or read the documentation, but having setgid bit on a directory causes all files within that directory to inherit the group. Normally it would also cause child directories to inherit the setgid bit in the permissions too, but I suspect that the fact that VersionSync is controlling the permissions via these two environment variables means that you need to tell it to explicitly set the setgid bit.

I doubt the setuid bit is needed though. I don't think that does anything (except allow executables to be run as a different user).

Regards,

Andrew.
