Weblate supports Python 3

During the last days I've completed quite long time challenge - make Weblate compatible with Python 3. It's probably still not in shape you would use it on production server, but it runs fine and the testsuite completes without errors.

As usual, the major obstacle are dependencies. The translate-toolkit doesn't support Python 3 in any released version, so you need latest Git snapshot. Another problematic bit is Mercurial, which will not support Python 3 in near future. But in case you need it, you can still install Python 2 version and use it from Weblate (it uses command line interface).

The porting was mostly dealing with encoding mess - in Python 2 you really didn't have to distinguish between binary and text data, while Python 3 quite enforces that. This turned out to be especially tricky with CSV files where csv module expects text streams in Python 3, while translate-toolkit CSV parser expects binary ones.

All this has one downside as well - the test matrix got bigger again, what makes the testsuite run longer with 5 workers available.

While doing these changes, I've also decided to drop support for Django 1.7, this will allow us to get rid of lot of deprecation warnings in Django 1.9 and prepare codebase for Django 1.10.

Weekly phpMyAdmin contributions 2016-W05

Last week was really focused on code cleanups. The biggest change was removal of PmaAbsoluteUri configuration directive, which has caused quite some pain in past and is not really needed these days (when browsers support relative paths in the Location HTTP header).

This lead to cleanup in other parts as well - support for dead Mozilla Prism is gone, used HTTPS for OpenStreetMap tiles (the map layer now works on HTTPS as well), removed ForceSSL configuration directive as this is something what really needs to be handled at web server level. To improve test coverage, several tests no longer require runkit as the header() call is wrapped within Response class and can be overridden for testing without using runkit.

The list of handled issues is not that impressive this week:

Bug squashing in Gammu

I've not really spent much time on Gammu in past months and it was about time to do some basic housekeeping.

It's not that there would be too much of new development, I rather wanted to go through the issue tracker, properly tag issues, close questions without response and resolve the ones which are simple to fix. This lead to few code and documentation improvements.

Overall the list of closed issues is quite huge:

Do you want more development to happen on Gammu? You can support it by money.

Gammu 1.37.0

Today, Gammu 1.37.0 has been released. As usual it collects bug fixes. This time there is another important change as well - improved error reporting from SMSD.

This means that when SMSD fails to connect to the database, you should get a bit more detailed error than "Unknown error".

Full list of changes:

  • Improved compatibility with ZTE MF190.
  • Improved compatibility with Huawei E1750.
  • Improved compatibility with Huawei E1752.
  • Increased detail of reported errors from SMSD.

New projects on Hosted Weblate

I had some pile of hosting requests in queue since half of January and my recent talk on FOSDEM had some impact on requests for hosting translations as well, so it's about time to process them.

New kids on the block are:

Second round includes:

Unfortunately I had to reject some projects as well mostly due to lack of file format support. This is still the same topic - when translating project, please stick with some standard format. Preferably what is usual on your platform.

If you like this service, you can support it on Bountysource salt or Gratipay. There is also option for hosting translations of commercial products.

Weekly phpMyAdmin contributions 2016-W04

As I've already mentioned in separate blog post we mostly had some security issues fun in past weeks, but besides that some other work has been done as well.

I've still focused on code cleanups and identified several pieces of code which are no longer needed (given our required PHP version). Another issue related to security updates was to set testing of 4.0 branch using PHP 5.2 as this is what we've messed up in the security release (what is quite bad as this is only branch supporting PHP 5.2).

In addition to this, I've updated phpMyAdmin packages in both Debian and Ubuntu PPA.

All handled issues:

Canon MF8540Cdn on Debian Linux

I've recently bought this beast and of course want to run it on Linux. Vendor does provide Linux drivers which even come with source, so that looked quite okay in the beginning.

However it turned out not to be that easy. First attempt was to install the 64-bit drivers and all I got from the printer is almost blank page with:

**** Unable to open the initial device, quitting.

Okay, that's not much helpful. Meanwhile I did install i386 system where it worked just fine. I started to smell some problems and looked at the source. It turned out to be almost complete, there was just single i386 binary, which is obviously needed by the driver.

Once realizing this, it was quite easy to make it work on 64 bit system as well:

dpkg --add-architecture i386
apt install libxml2:i386 libstdc++6:i386

Not that I'd be happy to run binary blob on my system, but at least printing now works.

Scanning from the device is easy - all you need to configure access to email and Samba and it works pretty without problems.

Security work

As you can now see on phpMyAdmin's security page, we've managed to spend 9 security announcements on todays release. Hopefully it won't continue that bad in rest of the year.

Anyway receiving such extensive report was really challenging for us - correctly tracking and fixing all reported issues, discovering which versions are affected. This proven to be quite difficult given that most of the affected code has been refactored meanwhile. But I'm quite happy we've managed to fix ll issues on three supported branches in two weeks.

Another challenge (especially for Isaac) was that this all came with change of our release manager, so forgive us some minor problems with the releases (especially not updated changelogs), we will do it better next time!

PS: Updated packages are on their way to Debian and phpMyAdmin PPA.

PS2: It seems we've messed few more things, so expect quick followup releases for older versions.

Weekly phpMyAdmin contributions 2016-W03

Last week consisted mostly of code fixes. For example the code for checking latest phpMyAdmin turned out to be buggy under some PHP configurations. But most work for last week is not yet public, you will see it in upcoming security releases.

All handled issues:

python-gammu 2.5

It has been quite some time since last python-gammu release and it's time to push fixes to the users.

This is really just a bugfix release collecting minor fixes and fixes testsuite with recent Gammu versions.

Full list of changes:

  • Compatibility with Gammu >= 1.36.7
