Communication was a lot more, just not these postings. Nuitka has ventured into important realms.
First, active developers have joined Nuitka. Second, as a consequence of the later, Nuitka indeed was able to participate with a insanely powerful offering of 4 mentors.
This meant, that a lot of technical or project management debt hat to be dealt with, and there was no time to make this kind of posting. This is probably good news on all fronts, except that I feel they are missing, and am glad to be able to resume them.
This was the most crazy ride and fun. Became the admin of an active sub-organisation under the PSF umbrella for GSoC 2019. So shortly after the announcement of the project lists, students flooded in, and starting working on things right away as early as February.
They were working hard to prove themselves and get to know Nuitka, asking many questions, with us having lots of email interviews, and even a lot of video calls, where I personally talked to people about ideas.
This happened simultaneously to more experienced developers joining the project as well, making very important contributions.
This basically meant, that many days 90%-100% of my Nuitka time was for communication or working off technical debts I knew there were, or for preparing things, I want to have with multiple people working on the code base. This will be detailed in other sections.
All of this has paid of in that we now have 2 really good students to work on 2 Nuitka projects over the summer. Let’s welcome Batakrishna and Tommy in separate posts. They will introduce themselves and what they are going to do shortly, in separate posts.
Lets just say, this is fantastic news. We had so many good applications and its a shame, but we knew right away, not everybody who deserved it could be picked. But this is going to be a good chance for us to get to be open and welcoming to new people.
So, the 0.6.3 release (btw. on Windows, be sure to use the 0.6.3.1 hotfix), which was made as a consolidation effort to get the good work of mostly other people out, didn’t contain much optimization work for the core, as that is still my thing.
However, this changed a lot. An idea that came to my mind for how to do the massive amounts of specialized helpers needed beyond + and +=, with which I had started for prior releases. And that is to use Jinja2 based templates for C, to generate the code.
This was an important idea. Took a while, but soon the manual code for
+ was already replaced with generated code, fixing a few bugs by the
way, and from there, the generation was expanded to cover
* as well.
Currently, support for the 3 (!) different kinds of additions
FloorDir as well as Python2 default division,
OldDiv in Nuitka was added along with
* were done first, is that they have special
treatment for sequences, using
the other operations will be more straightforward, e.g.
-) has a lot types supporting it and that makes those the easy
I am saving a deeper explanation of 3 things we will need for the next time. Basically we need optimization of these things at compile time, and that is getting there, and code to use in the backend, and that is getting there, and a third thing, that is to use optimization knowledge to apply the special code as much as possible, and that is not yet fully there.
This is going to excite Windows users. After Orsiris de Jong had done a replacement for dependency walker that is faster, this had remained in an experimental status, just due to lack of time.
Recently however, I felt there is more time, after GSoC student selection has happened, and that I could finally work a bit on open issues like this. And when I wrote a dedicated tool, to analyse dependences with either technology to compare the results, I found that dendency walker founds a lot more things.
That was a turn down, but turns out, nothing it finds is stuff that
should not be on the white list. In fact, it’s all core Windows things,
and from the
System32 folder. That made me question, why we take
anything from there (except maybe
PythonXY.dll) at all, and after
that change the performance changed dramatically.
The dependency walker now finishes a file in milliseconds. Actually the
pefile is now slow (surely it ought to be compiled), and takes some
seconds, for a file. That is amazing, and has lead to me to remove the
parallel usage, and since
pefile allows for perfect caching, and is
Free Software, we will probably keep it.
This will address a widespread complaint of many Windows users of the standalone mode. This is now a relatively unnoticable part of the overall experience.
Currently I need to finish off some remaining problems with it, before putting it out in the wild. Getting this into a release will solve many newcomer issues.
Esp. for Google Summer of Code, Nuitka has sought and found mentors, some of which are highly experienced for the task. I will let them decide and write their own introduction, but I feel really blessed by them helping me out in my desperate calls for help. Without them, neither could Nuitka participate, nor could it even overachieve as much as it does.
Therefore I welcomed Kamran and Vaibhav into the organisation and they are excited to work the the 2 accepted students, that are also added.
jorj branch there is a lot of work from Jorj that aims at
adding support for more of the beasty stuff with hidden dependency and
He is also working at run time tracing of your program to be translated to automatic imports of just that. I am going to highlight this later, once I manage to cherry-pick the release ready parts from it for the next release.
But this definitely awesome stuff, and going to make Nuitka very easy to use for some people, even with stranger software.
This is also a teaser. But we did so much work for the 0.6.3 release to make sure information is there, and things are accessible and changeable by everyone, or even the pre-commit hook that I am very proud of.
But I shall save this for next week, otherwise it will be too much new information.
I continue to be active there, although often I fall prey to of not wanting to talk about unfinished things. On Twitter of all things.
And lets not forget, having followers make me happy. So do re-tweets.
Adding Twitter more prominently to the web site is something that is also going to happen.
If you are interested, I am tagging issues help wanted and there is a bunch, and very likely at least one you can help with.
Nuitka definitely needs more people to work on it.
