Re: [Inkscape-devel] 0.91 performance when zoomed in (Saar Drimer)
by jelle
Hello Saar,
Indeed you found your culprit, but added to that I see a lot of
transparency objects in your design. If you have many layers as your
design does and each of those has transparent objects in them I can
imagine that things got a tad slow. Instead of a simple integer being used
to display a single colour every layer of transparency needs to get
calculated, added to the the previous one using floating point
calculations.
I imagine that this is handled on a logarithmic scale 1,2,4,8 etc. per
layer used or per overlapping object. If your bottom layers were masked
stacks of the same type of objects, I can imagine that the calculations of
the masks are applied after going through the whole object stack
calculation. Maybe using clips instead would make the result faster as
well as those are simpler calculations to my knowledge.
In any regard using lots of floating points explains the delay in screen
refresh as well. It certainly isn't the amount of nodes.
Cheers,
Jelle

0.91 performance when zoomed in (Saar Drimer)
by jelle
Saar,
Can you take a look at the objects using the XML editor and see what that
tells you? To me it sounds like you may have some opacity or blur filters
still going on. Also when you use the no filter display, is it still the
same? That should give a decent clue as to what is going on.
Cheers,

Hackfest catering and venue information
by Alex Valavanis
[Can ignore if you're not attending the Hackfest!]
Hi All,
Some information about the Hackfest venue, and a request for your
dietary requirements...
== Venue ==
The Hackfest venue will be in the Evans Room at Devonshire Hall in the
Hyde Park area of Leeds [1]. It is a traditional "Oxbridge style"
stone-built hall. Our meeting room will accommodate 10 delegates.
== Catering ==
A buffet lunch will be provided each day. I will suggest that we
break for lunch at 1300 each day, unless there are any objections.
Please let me know by tomorrow if you have any special dietary
requirements.
There will also be an unlimited supply of tea, coffee and biscuits.
Sugar, milk and soy milk will be provided.
== Facilities ==
* Wireless networking
* UK mains power (remember to bring your own socket adapters if you're
coming from outside the UK!!)
* Data projector & screen
* Flipchart and pens
== Nearby amenities ==
There are a few pubs, bars, cafes and coffee shops 5 minutes walk away
from the venue if we want a change of scenery. There is also a small
convenience store.
The venue is located on the Woodhouse Ridge nature trail if you want
to step out for some fresh air [2].
== Local contact ==
I live within walking distance of the venue. Send me a message if you
get stuck! I'll also be free on the Sunday evening before the
Hackfest if anyone would like to meet for food/drink in Leeds City
Centre.
Best wishes,
Alex

Re: [Inkscape-devel] Proposal for building Windows devlibs and for windows build environment setup
by Michael Soegtrop
Dear LRN,
> 1) I would suggest MSYS2 to be used (instead of Cygwin), as a shortcut, as
> it cuts down the number of packages that need to be built. Using MSYS2
> might also be faster (because compatibility layer will be thinner than
Cygwin).
I made quite extensive tests of cygwin with MinGW cross vs MSys2 and
came to the conclusion that cygwin requires much less patching and
messing around than MinGW for building most libs. The only advantage of
MSys2 is that GTK and all its dependencies are available pre-built, but
the MinGW GTK build on cygwin is fairly straight forward, it just takes
build time.
On cygwin I mostly use a generic download / configure / make / install
shell function for building. Some libraries need a patch or two, but
with cygwin this is the exception, not the rule.
I think that maintainability and cleanliness is more important than
build time, since most people won't touch the libs and build them at
most once a quarter. As long as it is fully automated, I don't care if
it takes 3 hours.
Another reason I finally settled with cygwin is that the scripts are 99%
identical to what is needed for a cross build on Linux. The deviations
with MSys2 tend to be larger.
But I guess this is a topic one can argue about forever. How about we
share our scripts, experience and ideas and work on both MSys2 and
cygwin+MinGW in parallel and see what is easier in the end? Most of the
work is solving specific build issues and it would be great to have
someone to discuss this.
I would suggest that we take this off list. I send you my scripts
stripped down to what is shared between inkscape and my original project
later today via private mail.
Best regards,
Michael

Git
by Krzysztof Kosiński
Eventually we probably need to move to Git. The user interface is
completely atrocious, but the fact it works from a single directory by
default is very convenient when using Eclipse, and Eclipse is an
elephantine monstrosity but has good code navigation. This could also
encourage more people to contribute, since almost all OSS developers
know Git, while a very limited number know Bazaar at this point.
The bug tracker and answer tracker should definitely stay on
Launchpad, but what about the code? Should we use Launchpad's nascent
Git support, or some other site like Github? What people think?
We can convert lib2geom first and apply the lessons learned to Inkscape.

Proposal for building Windows devlibs and for windows build environment setup
by Michael Soegtrop
Dear Inkscape Team,
I have a proposal for improving the delivery for the windows libs and
for setting up a build environment.
The current method of delivering binary libs has two disadvantages:
1.) it restricts the user to a very specific binary gcc build (at least
the docs say so).
2.) it is tricky to check if this delivery method is GPL compliant.
According to GPL if you deliver binaries you also have to deliver
sources, and it is a lot of work to check all libs licenses and to check
if all required sources are in the delivery. Please note that it is NOT
sufficient to say "this is standard GPL software and you can download
the sources from the official sources". If you delivery binaries, you
have to deliver the sources.
Now to my proposal: for another open source project I created 2 scripts:
one which automatically sets up a fresh cygwin with MinGW cross support
and whatever else is needed and another one which downloads and builds a
bunch of libraries and apps from sources, including GTK, cairo and
pango. About 70% of the libs inkscape requires are built by this script,
so it wouldn't be that much work to add the remaining 30%. This does not
just setup a build environment and builds everything automatically, it
also documents exactly what was used and how it was built (and possibly
patched).
So my proposal would be to instead of delivering the libs as binaries
and lengthy instructions just deliver these two scripts. The scripts are
fairly simple and well documented. The build for inkscape and all its
libs from scratch would likely be 2..3 hours on a decent machine.
Would others appreciate such a mechanism to build inkscape on windows?
Usually it would be a single call to a DOS batch file to setup cygwin
and start the download and build process.
Best regards,
Michael
