RecursionError: maximum recursion depth exceeded while calling a Python object

See original GitHub issue

On Ubuntu 20.04.3 LTS, I package the percol executable and run it with Nuitka as follows:

$ pyenv shell datasci
$ python --version
Python 3.9.1
$ pip  install -U nuitka 
$ pip list|grep -i nuitka
Nuitka                            0.6.19

$ git clone https://github.com/mooz/percol.git percol.git 
$ cd percol.git 
$ nuitka3 --follow-stdlib --follow-imports --static-libpython=no bin/percol
$ ./percol.bin

RecursionError: maximum recursion depth exceeded while calling a Python object

OTOH, if I use Nuitka with the following options, the above problem will disappear:

$ nuitka3 --static-libpython=no bin/percol
$ ./percol.bin 
                                    __
        ____  ___  ______________  / /
       / __ \/ _ \/ ___/ ___/ __ \/ /
      / /_/ /  __/ /  / /__/ /_/ / /
     / .___/\___/_/   \___/\____/_/
    /_/
                                 0.2.1 

You did not give any inputs to percol. Check following typical usages and try again.

(1) Giving a filename,

 $ percol /var/log/syslog

(2) or specifying a redirection.

 $ ps aux | percol

Any hints for fixing this problem?

The zstandard check has been implemented as part of today’s live streams, and will be on factory once it passes the CI. Actually now it will find any python that has it, and use it instead.

Yes, indeed, I was using this issue in part to drive things. The installed Python scan, previously used for Scons only, has been generalized, and is now used to find a suitable Python to do the onefile compression too. That allows compression with 2.6 or higher, as long as it can find another Python that has zstandard module, and also with the right version. So your setup would now may not have given an error, provided there is another Python.

Also means zstandard doesn’t have to be updated or installed in the compiling environment anymore, very nice. This will also open the avenue for code signing and other tools @Maxwell175, as we can now have a sort of helper Python and a compiling Python. Right now you can’t hint what the helper Python should be, but I will add that likely too.

With this, we can also consider using bootstrap on Linux as a user choice more clearly. Before it was loosing compression in many cases, now it will be better in all cases, except for the IO need, but the decompression speed of zstandard might make up for it depending on hardware relationship, RAM, disk speed, CPU speed on the target machine.
