crashtesting: now 92000 documents

crash testing, now 92000 documents continuously tested

Last August we had a collection of approximately 76000 documents. This July we have over 92000 documents. The corpus is mostly gathered from our bugzilla and other projects bugzillas via our get-bugzilla-attachments-by-mimetype script. For testing purposes we continuously import them all, and then export certain formats to multiple destination formats. For example odts are re-exported to odt, doc and docx and the results of what documents crashed (which includes asserts) are uploaded to the crashtest site

 

I like to imagine that these are typically the type of mean and bitter documents that try to eat innocent office software alive.

 

The get-bugzilla-attachments-by-mimetype script only downloads new attachments from its target bugzillas which are not already downloaded. The last run to refresh the corpus took over two days to complete. Refreshing isn't fast or cheap so it's fairly infrequent.

 

The regular crashtesting run to import and reexport the corpus is comparatively frequent, takes approximately 24 hours and typically gets run every two or three days on the latest 64bit Linux master in headless mode.

spellchecking calendar/calender

A short 2009 article about Microsoft's group with responsibility for spellchecking that mentions the calendar/calender masking problem. Sometimes you probably do want correctly spelled words to be flagged.

native gtk3 menubar in libreoffice

Following quickly on native gtk3 popup context menus is implementation of native gtk3 menubar and menus.

For comparison here's the (not utterly awful) emulated look prior to this. You can compare the spacing of elements in the menubar, menu separator rendering, distance of checkmarks to the following text, the display of the short cuts in different font attributes with different positioning, and menu entry line spacing.

This is mostly achieved by reusing the export of the toplevel menubar and menu structure via GMenuModel work by Antonio Fernandez and Bjoern Michaelsen and just stuffing a GtkMenuBar into a GtkGrid in the toplevel widget and moving the LibreOffice "guts" widget a level down with no LibreOffice menubar visible.

current LibreOffice native gtk3 elements

LibreOffice typically basically has just one gtk widget per top level window and draws everything you see itself, using the gtk themeing apis to make what it draws look like they do in gtk.

But there are some truly native gtk elements. Some of them new.

 

Tooltips

Tooltips, like the above transparent example, are real gtk tooltips now. Here's what they used to look like

 

Popovers

We recently in master began using GtkPopovers for informational messages such as the above calc formula formatting help.

 

Context Menus

As of today, context menus are native Gtk menus. This has the advantage of making managing overlarge menu scrolling all a gtk issue instead of faffing around endless in vcl to emulate what a native gtk menu would do. Flipping on/off mnemonics depending on keyboard input or whether the menu was launched by keyboard instead of mouse similarly becomes "someone elses problem". Here's the same menu launched via the menu key, automatically with mnemonics on start.

The menubar and menus launched from that menubar are currently still emulated ones, but they're the next target for nativization. We have mechanisms in place for the MacOSX and Unity menu integration that can probably be adapted and extended to support driving a native GtkMenuBar hosted in the GtkFixed-alike toplevel widget that fills each toplevel window.

gtk3 and LibreOffice

Couple of changes to the gtk3 support in LibreOffice master recently.

Theming stuff

The gtk3 support in master LibreOffice is now updated to support the relatively recent changes in gtk 3.19's style mechanism.

With mclasen's help I've added simple demos to the foreign-drawing demo of gtk-demo for the different elements that we render via those rendering apis. So what we attempt to do in LibreOffice is basically documented in gtk-demo now. So from 3.20 onwards if there are styling flaws in LibreOffice, then gtk-demo can be checked if it has the same problem or not.

Drag and Drop

Drag and Drop is now implemented in the gtk3 backend. DnD here includes moving blocks of cells around a calc spreadsheet using the mouse alone.

Wayland gstreamer video playback

If the gtksink gstreamer element is present (e.g. gstreamer >= 1.7.1 as in Fedora 24) then the gtksink gtk widget integration will be used to play video. Which means support for video playback in LibreOffice under wayland.

Better polygon rendering in LibreOffice's Gtk3 Support

Above is how LibreOffice's "svp" backend rendered rotated text outlines in chart where the text is represented by polygon paths. Because the gtk3 backend is based on that svp backend that's what you got with the gtk3 support enabled.

After today's work above is how the svp backend now renders those paths when rendering to a cairo-compatible surface such as the gtk3 support provides.

If we mandate that "svp" only operates on cairo compatible surfaces, then we can get this niceness into android and online too, and can ditch our non-cairo text rendering code paths.

Insert Special Character in Spelling Dialog

LibreOffice 5.1 spelling dialog now has a little toolbar to enable inserting special characters into the spelling editing widget. Also Added paste, so the insert icon isn't lonely.
