Porting wine to amd64 on NetBSD, third evaluation report
This report was written by Naveen Narayanan as part of Google Summer of Code 2019.
This report encompasses the progress of the project during the third coding period. You can make sense of the overall progress of the project by going through the first evaluation report and second evaluation report.
Wine-4.4 (released on Mar 2019) is working fine on amd64
and i386. I have been able to use a script as a workaround for
the problem of setting LD_LIBRARY_PATH. My patch for
setting guard size to 0 and hence, precluding Wine from
segfaulting, that got upstreamed, can be
found here.
I have updated the package to the latest development version of
Wine which is Wine-4.13 (released on Aug 2019). I have
added support to Wine pkgsrc packages to run tests using make
test, and at the time of writing, they are failing. I have also
noticed them fail on Linux non-pkgsrc environment and hence, will
require further investigation. Initially, they were disabled
owing to pkgsrc setting FORTIFY_SOURCE which is a macro that
provides support for detecting buffer overflows. In pkgsrc, the
wip/wine* packages honor PKGSRC_USE_FORTIFY variable passing
_FORTIFY_SOURCE macro accordingly. Programs compiled with
FORTIFY_SOURCE substitute wrappers for commonly used libc
functions that don't do bounds checking regularly, but could in some
cases. Wine unconditionally disables that via their configure
script because for some platforms that triggered false positives
in the past. However, in my experience, no false positive were
found.
Porting wine to amd64 on NetBSD, second evaluation report
This report was written by Naveen Narayanan as part of Google Summer of Code 2019.
This report encompasses the progress of the project during the second coding period.
As getting Wine to work with WoW64 support was of foremost
importance, my focus was on compat32 dependency packages without
which Wine's functionality would be limited and more importantly
untestable. Initially, being unaware of what to expect, I just
wanted Wine to run, at the earliest. So, with outmost support from
mentors, the consensus was to install libs from 32-bit packages to
${PREFIX}/lib/32 and ignore everything else that came with the
respective packages.

Porting NetBSD to HummingBoard Pulse, Part 1
This report was written by Saurav Prakash as part of Google Summer of Code 2019.
My venture into the first phase of The Google Summer of Code is nearing an end. The experience was enriching in every dimension, and the learning exposure I was subjected to was genuinely worthwhile. Here is a brief report on the work I have performed during this coding period.

Porting Wine to amd64 on NetBSD, first evaluation report
This report was written by Naveen Narayanan as part of Google Summer of Code 2019.
I have been working on porting Wine to amd64 on NetBSD as a GSoC 2019 project. Wine is a compatibility layer which allows running Microsoft Windows applications on POSIX-complaint operating systems. This report provides an overview of the progress of the project during the first coding period.

LLDB from trunk is running on NetBSD once again!
Upstream describes LLDB as a next generation, high-performance debugger. It is built on top of LLVM/Clang toolchain, and features great integration with it. At the moment, it primarily supports debugging C, C++ and ObjC code, and there is interest in extending it to more languages.
Originally, LLDB was ported to NetBSD by Kamil Rytarowski. However, multiple upstream changes and lack of continuous testing have resulted in decline of support. So far we haven't been able to restore the previous state.
In February, I have started working on LLDB, as contracted by the NetBSD Foundation. LLDB used to work on NetBSD before but the support recently regressed. Therefore, my four first goals as detailed in the previous report were:
Restore tracing in LLDB for NetBSD (i386/amd64/aarch64) for single-threaded applications.
Restore execution of LLDB regression tests, unless there is need for a significant LLDB or kernel work, mark detected bugs as failing or unsupported ones.
Enable execution of LLDB regression tests on the buildbot in order to catch regressions.
Upstream NetBSD (i386/amd64) core(5) support. Develop LLDB regression tests (and the testing framework enhancement) as requested by upstream.
Of those tasks, I consider running regression tests on the buildbot the highest priority. Bisecting regressions post-factum is hard due to long build times, and having continuous integration working is going to be very helpful to maintaining the code long-term.
In this report, I'd like to summarize what I achieved and what technical difficulties I met.

Google Summer of Code 2017
NetBSD participated in the 2017 edition of Google of Summer of Code with 3 students. All of the students finished their projects successfully. The following links report about their activities:
- Leonardo Taccari: Add multi-packages support to pkgsrc
- Maya Rashish: LFS cleanup
- Utkarsh Anand: Make Anita support multiple virtual machine systems
Announcing NetBSD and the Google Summer of Code Projects 2017
We are very happy to announce that the selection process in this year's Summer of Code with its bargaining of slots and what student gets assigned to which project is over. As a result, the following students will take on their projects:
- Leonardo Taccari will work add multi-packages support to pkgsrc.
- Maya Rashish will work on the LFS cleanup.
- Utkarsh Anand will make Anita support multiple virtual machine systems and more architectures within them to improve testing coverage.
) until August 21st, evaluations, code submission and an announcement of the results on September 6th 2017.
Good luck to all our students and their mentors - we look forward to your work results, and welcome you to The NetBSD Project!
NetBSD fully reproducible builds
Today (2017-02-20) NetBSD got our first reproducible build on the debian build farm. Here's a short description how we got here, what implementation choices we made, and what we had to fix.[Read More] [4 comments]
Firefox 51 on sparc64 - we did not hit the wall yet
Keeping a current firefox working is a tough task. All NetBSD architectures are "tier 3" from the Mozilla foundations point of view.
Onodera-san (who does most of the pkgsrc work for mozilla based pkgs - and others) does a great job.
And on "strange" architectures like sparc64 it is even worse...
