Wrote a short Samba patch to fix up display of the print queue when using the version of LPRng that came with RH7.3 as a print spooler. One of the new features in that version of LPRng was that it leaves one or two jobs in the print queue marked as done (apparently this was done for accounting purposes).
Unfortunately, Samba was not expecting to see jobs marked as “done” (it assumed that jobs marked “active” were being printed, jobs with a numeric rank were queued, and all other jobs were paused). This was causing a lot of confusion at the office, as Windows would not realise that print jobs had completed.
It was fairly trivial to find out what to patch in the Samba source code to fix this, so in about 20 minutes I had things up and running, and the complaints went away. It was much easier to find the correct part of the code to patch than with some other programs I have had to make modifications to.
PyGTK
In my last diary entry, I talked a bit about how long delays between releases of a package can hurt. It has been almost 2 months since the last 1.99.x snapshot of PyGTK. I will look at putting out a new release tonight after applying Arjan’s closure cyclic garbage collection patch and fixing a tree bug jrb pointed out.
A lot has changed since the last release, so it would be good to get people trying out the new version. It is probably possible to implement proper widgets now, which is a big milestone.
After the release, I will look at implementing some nicer ways to use list store and tree stores:
- len(liststore) should return the number of elements in the list.
- liststore[index] or treestore[treepath] should return an object representing the row. getting and setting indices on the row should get/set the appropriate values in the tree.
- iter(liststore) should return an iterator that returns instances of the above row objects. Haven’t thought about iterating over tree stores.
These should help make the new tree widget feel more python-like, which is helpful.
