Samba 4 progress

meta = {'category': samba, 'date': Mon 12 February 2007}

I’ve been busy getting some more of my pending Samba 4 work merged. In the past week, I’ve worked on:

  • Getting the registry branch Wilco and I have been working on ready to be merged
  • Moved out the GTK+ stuff of the main tree into a separate one
  • A bunch of improvements to the build farm. Mainly refactoring code so we can switch to using a database backend
  • Random pidl improvements (mainly better warnings and errors)
  • Rewritten test interface in perl with the ability to run tests in a more fine-grained way

It looks like I’ll be mainly working on pidl stuff for the next few weeks and then on GSSAPI support for CIFS VFS.

My blog now also has a real-life tag, in case I’d ever want to post about things other than travel or free software stuff.

Code coverage testing

meta = {'category': samba, 'date': Tue 23 January 2007}

Over the past week or so, trying to make sure all my code is covered by the unit tests, I’ve been playing with gcov and various other code coverage tools. Especially lcov and perls’ Devel::Cover give very nice, browsable HTML output.

Test code coverage for some of the projects I work on:

Bazaar

meta = {'category': bazaar, 'date': Thu 18 January 2007}

Now that I have some more time to spend, I’ve done some more work on Samba 3 and 4. In particular, I’ve resolved a couple of pending DCE/RPC issues. I’m now looking at improving the test runner a bit, so that it shows progress.

I released bzr-svn 0.3 a couple of days ago, a couple of hours after the first release candidate for Bazaar 0.14. The main focus has been on reducing the number of bugs. That’s resulted in a large number of repositories now working with bzr-svn. In fact, all of the repositories I’ve tested so far work.

It’s going to be another Bazaar-heavy week next week at the Bazaar sprint Wouter and I are organizing in Amsterdam.

More use of IDL

meta = {'category': samba, 'date': Mon 25 September 2006}

The IDL (r)evolution is really taking place now. We’re slowly getting rid of the Samba3 DCE/RPC parsers that we were previously using and are moving towards new code generated from the IDL by pidl.

An increasing amount of dissectors of wireshark is now also generated from IDL, thanks to the work of Ronnie Sahlberg. There’s a list at their wiki.

New job

meta = {'category': samba, 'date': Sat 02 September 2006}

Google’s Summer of Code was again a pleasure to participate in! I’m quite pleased with the overall results and have enjoyed working on the CUPS tree. Mike, main author of CUPS, has merged my Kerberos branch into trunk a couple of days ago. It should be part of the upcoming 1.3 series. My aim is to stick around and maybe work on SPNEGO/NTLMSSP support.

As of recently I have started working part-time for SerNet. I’ll be working on random Samba bits for them, all free software. The first thing I’m working on is backporting the excellent libndr (one of the core parts of DCE/RPC) subsystem from Samba 4 to Samba 3.

The university year has also started, so my activity in free software will probably decrease a bit in a few days.

Using bzr-svn in production

meta = {'category': bazaar, 'date': Wed 19 July 2006}

At last, I’ve started to use bzr-svn in production. I’m now working on Samba in bzr, pulling from and pushing to Subversion branches as if they were native Bazaar branches.

It seems to work quite well. Bazaar can be slow dealing with large history, but that appears to be a temporary issue rather than a design flaw.

I’ve also published conversions of the two main Samba branches on the web at http://people.samba.org/bzr/jelmer/samba/.

Now, time to get the Subversion Python fixes into all the distro packages.

Upcoming talks

meta = {'category': samba, 'date': Fri 31 March 2006}

I will be giving talks on Samba talks during three upcoming events: SambaXP 2006 (25 April), The Free Software Bazaar at SANE 2006 (17 May), NLLGG meeting, 2006 (10 June).

The first two talks will focus on Samba 4 and its current state. The third will be a generic introduction to Samba.

pdbsql finally working again…

meta = {'category': samba, 'date': Tue 21 March 2006}

I was glad to see that pdbsql is finally somewhat stable again, thanks to Wilco’s help. It’s always bad to see good code bitrot. Luckily, that’s not going to happen here :-)

Samba 4 Status Report Edition 6

meta = {'category': samba, 'date': Tue 21 March 2006}

It’s once again been a busy week for Samba 4.

Simo has worked on making more of the LDB code asynchronous.

Metze has reworked some of the NTVFS code to be generic for use by both the smb and smb2 subsystems. Tridge and metze have worked on inotify support. Tridge fixed a bunch of bugs, reported by a static code analyser.

Andrew fixed several bugs, mostly auth-related and improved some of the tests.

Rafal has made more of the DCE/RPC subsystem asynchronous, in particular the connect bits.

I spent it working on various bits of the build system; we now support using shared libraries internally. All modules can be built as .so files and all subsystems (including LDB) support loading extra functionality using .so files. Try it out by running “./configure —enable-dso”. This should make it much easier for other projects to use parts of Samba or hook into Samba. Automatic dependencies are now also generated; just on GNU make 3.81 and higher for the moment though, as older versions appear to be buggy.

The registry (just the core, not all backends though) now keeps track of credentials information. A feature which Andrew had been asking me about for ages but which I kept postponing. :-)

A more detailed list can be found in the WHATSNEW.txt prepared for tomorrows’ release.

I’m planning on releasing TP 2 tomorrow morning. Everything seems stable - and the release is long overdue (originally planned to be at the end of february).

Samba 4 Status Report Edition 5

meta = {'category': samba, 'date': Mon 13 March 2006}

It’s been another busy week for Samba 4. I’ve been so distracted with actual development the last couple of weeks that I haven’t actually had time to post an update report on it.

Metze and I have been working on making some of Samba4’s internal files build as shared libraries. The idea is that we will later be able to ‘export’ libraries and make them easily available for others to use (GNOME, KDE, OpenChange). At the moment, we have support for shared libraries partially finished. Those interested in checking it out can do so by passing —enable-dso to the configure script.

Tridge has been working on inotify support in the NTVFS layer (file change notifications).

Rafal (mimir) has made the core of the DCE/RPC layer asynchronous.

Of course, there have been a lot of smaller changes as well.

It’s been a busy week for Samba, overall. After Coverity published a list of potential bugs found by their static code analysis tools, Samba3 development got a major boost. In the meanwhile, we’ve delayed TP2 again. We’re now waiting until things settle down, hopefully in the next few days.

pdb_sql moved out of tree

meta = {'category': samba, 'date': Mon 20 February 2006}

The original project that got me working on Samba, pdb_mysql has been moved out of the Samba tree. There’s been quite some discussion about this in the past few months, after several grave usability bugs that indicated I wasn’t maintaining it actively enough (I haven’t actually used it for a few years now).

After some discussion, the pdb_sql modules have been removed from the SVN tree and now Florian and some other folks have picked it up and are continuing development as a seperate project. It’s been a bit hard letting go, but also good to see the source code isn’t going to bitrot away in the deep archives of the internet.

Moving forward to the next ‘tipi’

meta = {'category': samba, 'date': Fri 27 January 2006}

The first technology preview for Samba 4 has sparked quite a bit of interest from users and we have already received several bugreports. At the moment, all work is focused on the next ‘tipi’ for which we have set some milestones. The target date is sometime next - hopefully just before FOSDEM.

Linux.Conf.A has really been great so far. It’s a by far a nicer and more technical conference than any I have attended in Europe.

Samba 4 TP 1 Unleashed

meta = {'category': samba, 'date': Tue 24 January 2006}

So, today was the day… we have just released the first Technology Preview of Samba 4. It is still a long way for release, but we hope it will attract some attention of the community and result in useful bug reports and suggestions.

While I built the final tarball and did the announcement, Andrew Bartlett was the main force that finally made this release happen. He worked hard over the past few months to fix the remaining issues that were required to make Samba 4 actually usable.

Meanwhile, several large sites have picked up the announcement, news.samba.org has a list.

Samba4 Debian packages in experimental

meta = {'category': debian, 'date': Fri 06 January 2006}

In the past week, we have migrated the Debian packaging for Samba 4 to the SVN repository of the Debian Samba packaging team at alioth.

Mostly thanks to the hard work of Steinar Gunderson in the past week, the packages are now ready for, and have been uploaded to Debian experimental. Most importantly, there is now integration for upgrading from Samba 3 to Samba 4 using the upgrade scripts.

I will no longer upload Samba4 Debian packages to jelmer.vernstok.nl.

New Samba4 Debian packages

meta = {'category': samba, 'date': Sun 18 December 2005}

Thanks to the help of Steinar Gunderson in the past week, the Debian packages of Samba4 have had some major improvements. I have once again started to provide snapshots. As usual, they can be used by adding the following line to your /etc/apt/sources.list:
