[REQUEST] python311

Hi everyone!

Please, I need help with an update to the package python311. Particularly, in the package version (pkgver), because there is a new version in the official repository Python 3.11.10.

Also, I found a wrong package name in the "makedepends" list. Actually the package "bluez-libs" is used, and should be used the "boost-libs" pkg.

I don't know if is it necessary tag the maintainers, but I'll really appreciate the help with these changes.

Re: [REQUEST] python311

Sorry, I forget something, is it possible add the flag "--enable-optimizations" to the configure process?. This is for clean temp files of the previous compilations.

This have the "Readme.rst" file:

Profile Guided Optimization

PGO takes advantage of recent versions of the GCC or Clang compilers.  If used,
either via ``configure --enable-optimizations`` or by manually running
``make profile-opt`` regardless of configure flags, the optimized build
process will perform the following steps:

The entire Python directory is cleaned of temporary files that may have
resulted from a previous compilation.

An instrumented version of the interpreter is built, using suitable compiler
flags for each flavor. Note that this is just an intermediary step.  The
binary resulting from this step is not good for real-life workloads as it has
profiling instructions embedded inside.

After the instrumented interpreter is built, the Makefile will run a training
workload.  This is necessary in order to profile the interpreter's execution.
Note also that any output, both stdout and stderr, that may appear at this step
is suppressed.

The final step is to build the actual interpreter, using the information
collected from the instrumented one.  The end result will be a Python binary
that is optimized; suitable for distribution or production installation.

Re: [REQUEST] python311

Why in the world are you using that package? It shouldn't even exist as it does.

Just use the 'python' package in Extra. 3.12 didn't break that much, unless you've got a very specific use-case.

Do you mean bluez-libs should be replaced by boost-libs in makedepends?

Cleanup is already provided by makepkg see the -c and -C options.

I need this version to run llm models using the mlc engine. I use the vulkan driver and miniconda envs give me errors in the execution.

In a server mode environment this can open unexplored backdoors, but maybe I'm wrong.

Done!, Thanks!

The 3.10 version has the flag "--enable-optimizations" and this not, in the "configure" process.

Re: [REQUEST] python311

Besides, we would recommend using Python 3.11;

Have you tried running it with python 3.12 or python 3.13 (python 3.13 rebuild has started in staging repo, so it will enter extra in the next few months) ?

Do you mean having bluez-libs on the system during package build opens unexplored backdoors or building python's socket module with bluetooth support opens unexplored backdoors?

Why must cleanup be performed by configure instead of makepkg?

I try with the 3.12, but I've gotten an error compiling the Apache TVM fork. The version 3.13 was released the last week, so no.

Both, I don't need the bluetooth working in my server, but again, maybe I'm wrong because is a personal use case.

The cleanup is the first step of the conf, the real target of this flag is:

Building relax worked for me. Possibly a difference in the cmake options you used or what you have installed on your system?

That makes sense for your use case but why make that the default if you do not know of any actual issues it introduces when it removes functionality? What functionality does adding boost-libs add to the build?

I compiled the 3.11.10 version without that lib, and I had no problems, but you're right.

It's to get a better PyTorch's performance, but again, It's for a personal use case.

I searched through the 3.11.10 I could not find any use of boost. Also adding boost-libs which do not contain headers to the build would most likely not have any effect even if boost could be used:

Re: [REQUEST] python311

The bluez-libs dependency was introduced 11 years ago: https://gitlab.archlinux.org/archlinux/ … 81456089d6 and reintroduced again with FS#70438 after deemed necessary.
