[Oscar-devel] RE : RE : OSCAR GUI

[LAHAYE O. <oli...@ce...>]

hi,

I understand what you mean, and this makes sens. I dislike a lot tcl/tk + perl-Qt3 either. perl-Qt3 will be a big problem to replace when distro will abandon qt3 support.
the Tcl/tk interface is for sure not intuitive and buggy. package descriptions are truncated, setup networking buttons are half freezed when MAC aquisition is on, and such, but for the moment, it works, so, yes, V7 could include this change.
For the database, I agree that mysql is big comared to its load, but it's easy to manage by everyone and it works fine. Moving to another database or berkley db system will make it harder to update the database by hand in case of problem (and need developpement). For sure, the end user is not meant to manage by hand the database, but perfection is not in this world and sometimes it's cool to have the ability to do a mysql -u root oscar...

IMHO, the priorities for the moment are:

- Make a stable release for centos-6 and other recent distros (debian, fedora, maybe suse). V6.2 ?
- fix build system so external missing packages like perl-Qt, systemimager, aftp, bittorent, flamethower, ...are built
  fix build system so opkg are in pkgsrc allowing a package upgrade without requiring a new oscar release. V6.3 ?
- Fix packages like gridengine (sge is broken and obsolete) and maybe others V6.4
- Add cluster management utilities (put nodes offline for maintenance, move jobs, hybernate cluster, update cluster (packages), deploy rpms, ...) V6.5
- Prepare for the future: pre-V7
   - Update / rewrite GUI
   - move to modern architecture (systemd, ...)
   - detach database backend

Best regards,

Olivier.

PS: I'm still working on systemimager (stuck with dhcp that fails to detect broadcast interface)

Objet : Re: [Oscar-devel] RE : OSCAR GUI

A reasonable perspective. Those are all good things to prioritize.

DongInn seemed to be suggesting a GSoC project. I think GSoCs are more
geared toward something like a new interface and not general code
maintenance. In that respect, I think, a new GUI might still be a good
project (particularly if the oscarcli was fixed in the process).

I'm not a big java fan either. Javascript is not java, but java may
have been implied anyway. The current Tk interface works, but is not
always intuitive. As for the databases, I just wanted to point out the
duplication of function and suggest something lighter or integrated. I
think these database instances have so few writes that they could be
replaced with something like sleepycat. Granted, mysql has not been a
big problem to date, but it is a complex beast and complexity can
introduce problems. By saying v7.0, I intended to imply not a high
priority.

I've been in contact with developpers, and the project is not dead. v0.4 will be released some day. The TODO says that in the future, we should be able to choose the database backend. (no work done yet though).
