Re: powerpill reborn: pacman wrapper for faster downloads

Hi Xyne,
Is it possible to ask confirmation before download everything in powerpill and bauerbill? And add to bauerbill posibility to edit PKGBUILD files? Used to do it very often, when I used yaourt.

Re: powerpill reborn: pacman wrapper for faster downloads

There is a problem, when there are many packages to download via rsync, as rsync has hard coded arg limit of 1000. Maybe this should be considered in powerpill, so that so many packages are not downloaded with a single command.

Re: powerpill reborn: pacman wrapper for faster downloads

@x4fyr
Are you hitting a 1000 package limit on a regular upgrade? I'm just curious because you're the first person to report the issue.

I've added the dealing with the limit  to my todo list and will try to get to it soonish.

Re: powerpill reborn: pacman wrapper for faster downloads

It was a regular upgrade on a system I haven't used some months. I dont think too many people use powerpill+rsync and don't upgrade their system with many packages that infrequent. Imho it is a very special case, so no hurry needed.
I circumvented it, by first upgrading just core and then the rest.

The limit in rsync is actually not 1000 files but 1000 arguments. So it will be a bit less, as the options will count into the limit, too.

Re: powerpill reborn: pacman wrapper for faster downloads

Rsync commands are now split and run in parallel to handle the limit.

Re: powerpill reborn: pacman wrapper for faster downloads

I just noticed that when I try to install "nvidia-utils", powerpill tries to download a different package named "nvidia-340xx-utils" that has that nvidia-utils name in its "provides=..." PKGBUILD setting. Here's the output when I stop it with Ctrl-C:

$ sudo powerpill -S nvidia-utils

Re: powerpill reborn: pacman wrapper for faster downloads

@cradlemann
This won't help you edit packages manually, but I believe it is possible to set up a script bauerbill uses to modify specific packages. There's a section in the json for per package scripts, I believe.

@xyne
With the pacman update for delta3 should we still be using rsync, or both rsync and delta3 for the best download times?

Re: powerpill reborn: pacman wrapper for faster downloads

There was no pacman update for xdelta3. xdelta3 has *always* been an optional dependency of the pacman binary, *if* you have a repository which provides delta packages, which the official ones do not.

Recently the pacman PKGBUILD was updated to reflect this longstanding fact, but that is merely advertisement, not implementation of a feature. wink

Re: powerpill reborn: pacman wrapper for faster downloads

@eschwartz

Ah, alright. xdelta3 was just, recently, split off from pacman to a separate package, or updated to be listed as an optional dependency?  Yeah, there's just that one guy advertising on the forums about having an xdelta3 server setup.

@xyne
Is my hooks array setup correctly? I have the script in /etc/bauerbill/hooks/linux-ck/prebuild.

  "hooks" : {
    "directory" : ["/etc/bauerbill/hooks"],
    "arguments" : {
      "default": ["{PackageBase}", "{LastModified}"]
    },
    "commands" : {
      "prebuild" :  {
	"linux-ck" : ["linux-ck_modify.sh"],
        "default" : []
      }
    }
  }

I noticed another user had the same issue and they wrote about it on the AUR page, and you replied.

My /usr/lib/python3.7/site-packages/Powerpill.py and the source archive Powerpill.py are identical.

Re: powerpill reborn: pacman wrapper for faster downloads

I'm seeing the stack trace same thing as raggerv8 above.

It appears to be due to an update in pyalpm package. If I downgrade to version 0.8.4-2, then powerpill works without a problem. However, upgrading to 0.8.5-1 or newer, causes this to break with that same import error.

edit: looking into this more, it looks like pyalpm completely changed the format of pycman/config.py, just looking at relevant part of the diff to the import error in the stack trace:

diff --git a/pycman/config.py b/pycman/config.py

I guess python3-xcpf needs to be updated to handle all the changes in pyalpm?

It's from all of the free floating config functions being placed in a class in pyalpm, PacmanConfig.

Re: powerpill reborn: pacman wrapper for faster downloads

Thanks for the heads-up, but the error is in pyalpm. Please test pyalpm-git. If the error has not been fixed there, please report it to the pyalpm devs.

Re: powerpill reborn: pacman wrapper for faster downloads

@SolarAquarion
Thanks for notifying me of the errors, which were due to changes in makepkg in pacman 5.2.0. These have been fixed in bauerbill-2019.

For future bauerbill errors and feedback, please post in the Bauerbill thread.

Re: powerpill reborn: pacman wrapper for faster downloads

Please use the full path to python when launching the application.

In the powerpill application, I see

python3 -m Powerpill "$@"

Today I got the error: /home/c/.pyenv/versions/3.9.1/bin/python3: No module named Powerpill
This because I manage some local python using pyenv, so I had to run

pyenv global system

for powerpill to work

I use yay as my AUR helper.

Re: powerpill reborn: pacman wrapper for faster downloads

It really isn't the job of the single application/utility to workaround your environment. Why are you running a system package within your local build/pyenv environment?

I wasn't trying to run it within the pyenv environment. I use pyenv for other python stuff. Yay always displays a warning when run with sudo, so I don't always use sudo to run it, which is why it picks up stuff from my user's environment.

Anyways after searching a bit, I created the following alias for running yay.

alias yay='env --ignore-environment sudo --login --user="$USER" yay '

Feel free to judge

Re: powerpill reborn: pacman wrapper for faster downloads

Python software really should be getting launched via wrapper scripts looking like this:

#!/usr/bin/python3

import sys
from Powerpill import main

sys.exit(main())

There is zero reason to wrap everything in bash just to interpose another process -- unless wasting a few CPU cycles is a reason. Setuptools entry points handle this seamlessly and get installed during "python3 setup.py install", reducing the number of lines in a PKGBUILD.
Setuptools entry points also guarantee the #! shebang points to the absolute path of the python executable used to perform "python3 setup.py install", meaning no env lookup, meaning it is guaranteed to never run in a virtualenv, regardless of your interactive shell environment (unless it was installed from a virtualenv, in which case it will *always* run in that virtualenv).

Nevertheless, the bash entry point (and the one-file command line tool installed as a module to begin with) is a classic feature of Xyne software. wink

Anyway. Yeah. There's ways to fix this, and even ways to simplify packaging *and* be more correct about it which just fix this by accident.
