This is my (in)activity log. You might like to visit
Productivity a subsidiary of Collabora focusing on LibreOffice support and
services for whom I work.
Also if you have the time to read this sort of stuff you could enlighten
yourself by going to Unraveling Wittgenstein's net or if
you are feeling objectionable perhaps here.
Failing that, there are all manner of interesting things to read on
the LibreOffice Planet news
Stuff Michael Meeks is doing
Up early, now Apache have some code available, I did a
quick analysis of the LibreOffice diff to Apache's codebase - which
is fairly large and growing: looking
only at C++ files (
*.?xx) we have:
What does that all mean ? well it is a lot of code-change and cleanup.
It is also a lot of scope for conflict when merging changes. Seemingly
there is an assumption, that code committed
to Apache OpenOffice will inevitably and automatically appear in
LibreOffice. This looks increasingly unlikely. Instead I suspect we
will end up cherry-picking and porting only those things that justify
the effort, as/when/if there is any such thing.
- We removed ~678 files (though some small proportion
of these are simple movements to improve encapsulation
and/or re-use). A hundred or so of the removals are obsolete binfilter
pieces, 55 from OS/2 code, 50 from adabas and evo1 connectors,
38 from soldep, 36 from killing vos, but many more bits of unused
- We added ~914 new files modulo movements
the single biggest chunk is : 380 files is (IBM's) lotuswordpro
filter (forward-ported by us), then it gets bitty: VBA improvements,
the re-written RTF import filter, the ODMA and KDE file pickers,
OpenXML filter work, new unit tests, gtk3 pieces, AIX UNO bridge,
svg filter and lots more.
- These numbers compare with 21.5k common files overall.
As a reasonably useless statistic - but perhaps one that points
helpfully to the likelihood of merging conflicts we have ~2 million
diff -u output over 7.7 million
newlines of code.
More concretely, having elided the code changes from the
(automated) emacs & vi modelines (to make editing much easier)
which touched each file, and looking only at common files we
have: minus 526k lines - always good to measure the negatives
first: we ripped and replaced a lot of cruft. And then we added
290k lines back again.
Naturally, lots of feature work was done in the new files
we added, so the net work input is much larger, the above number is
only looking at the common files; to gague the degree of code-change.
Pain in jaw (again) - an annoying intermittent wetware bug.
feature/gtk3 branch and built it. Did some
hacking on windows to try to unwind some unit test breakage,
remembered again why I hate using that thing. File URLs that look
file:///c:/foo/baa which inevitably break when
ported from unix Incremental (no
action) re-make time of the order of a minute instead of a handful
of seconds - amazing.
Of course, no doubt cygwin has a lot to do with the slowness, but
wow life is painful without that glob fix (which saves a ton of
un-necessary I/O). It -really- looks as if we should be building
with our own make snapshot on windows.

Tested Moggi's nice merged cells movement / undo/redo fix -
lovely. Poked at Bjoern's nice gerrit instance - looks easy to get
going at least.
Poked at the GTS
library to see if it could be used for 3D shrinking / slicing
for repsnapper, looks rather impressive
(though apparently sadly unmaintained).
