crash testing, 1 export failure, 0 import failures

I graphed our crashtesting improvement on importing documents a while back, and mentioned that while import failures had improved dramatically that the export figures weren't as shiny. But there's been some great progress there too, especially with the work mstahl has been putting in, so today the crashtesting has reported effectively three consecrative 0 import failures and with the first drop to 1 reported export failure (an assert) so I present the graph of export failure progress

 And an updated import crashtesting graph.

This is on our corpus of 76000+ documents sucked down from various bugzillas and other sources.

Equalize Width/Height

In LibreOffice 5.1 I've added an equalize width/height pair of adjustments to the "shapes" submenu when multiple objects are selected. Equalize Width and Equalize Height which adjusts the width/height of the selected objects to the width/height of the last selected object.

So if you need to adjust the shapes of a bunch of little images and shapes. Adjust one, then select the lot, selecting the reference one last, and use these to update the rest of the sizes.

Impress Slide Design

Selecting multiple slides in normal view and using the slide design dialog will now affect all the selected slides as opposed to the single last selected slide in 5.1 onwards.

gtk3 clipboard support implemented

Our LibreOffice gtk2 vclplug inherits from our generic X11 vclplug and so in lots of places we just continued to use our historic X11 vclplug for various things, one big example being clipboard support.

To do the same with the gtk3 vclplug would work for the case where gtk3 is backed by X11, but not if backed by wayland. So we needed to implement cut and paste with the gtk3 apis.

X clipboard/selection/cut and paste is errr... "tricky", so it was a bit of a death march to drag myself to the keyboard to go about this. But it turns out the gtk clipboard apis are really good and its reasonably easy to get it up and running. So the LibreOffice gtk3 vclplug now has clipboard support.

Last major thing is to get gtk3 gstreamer integration working for video playback and then it's mopping up territory.

crash testing, 1 import failure

moggi described here our crash testing infrastructure. Basically we have a document horde mostly populated through get-bugzilla-attachments-by-mimetype which downloads all the attachments from our bugzilla (and a whole bunch of other bugzillas) that are in formats which LibreOffice can open. We then import the lot of them with the above testing harness looking for crashes and aborts. A new report tends to appear every 1-3 days.

These documents are filed in bugzillas. In many cases they were filed specifically because they were causing some sort of trouble for someone, so there are a lot of hostile documents in there.

We currently have 76221 documents in the horde, the most recent run reports one, one single solitary failure (an assert in a .doc about invalid positioning of a cross-reference bookmark in a document with change-tracking enabled).

Here's a graph over time of our failure rate. Where failure is either a straight forward crash, or a triggered assert. The builds are dbgutil, extra-debugging, extra-checking, assert-enabled, exception-specification-enabled builds.


You get temporary local peaks every now and then when either a new assert is added or someone introduces a bug. We have two purposes here, immediate regression discovery and historic bug removal.

We also have export crash testing, where the numbers aren't as shiny yet, but are on an equivalent downward trend. More on that in a while when we figure out how to fix this final import stinker.

more gtk3 theming

Continuing on the Gtk3 theming work. Now got the combobox and editbox rendering and sizes correct along with new gtk3-alike focus rectangles. Here's the after...

Here's the before of what the gtk3 effort looked like in 4-4
Here's the equivalent 4-4 gtk2 effort. Note that now in the above gtk3 theming we have a single focus rectangle for the full combobox rather than a focus rectangle around the non-button part of the widget and that, as in a normal gtk3 combobox, the background isn't set to blue when selected. I always hated that out of character blue listbox/combobox selection color. So certain elements of the gtk3 theming now slightly surpass the gtk2 one which is nice. Though clearly the spinbuttons are still effectively imaginary ones as they look nothing like the native gtk3 ones.

I also fixed (for both gtk2 and gtk3) that notorious checkbox issue where unchecking a checkbox would leave a portion of the check still drawn outside the checkbox rectangle.

new area fill toolbar dropdown

The GSOC 2014 Color Selector is in LibreOffice 4.4, but it's not used for the "area fill" dropdown in impress or draw. So I spent a little time today for LibreOffice 5.0 to hack things up so that instead of using the old color drop down list for that we now have the new color selector in the toolbar instead. Gives access to custom colors, multiple palettes, and recently used colors all in one place.

LibreOffice 5.0
And here's the old one for reference, I've backported the above change to Fedora 22's 4.4.X to address some in-house vented frustration at selecting colors in impress.
