No output on MacOS/Python 3.8 about austin HOT 10 CLOSED

@RhetTbull Thanks for the further feedback. I should have fixed the problem now. I have tested with Anaconda (Python 3.7 and 3.8) and Python 3.8 from Homebrew and all seems to work as expected now. I would really appreciate if you could pull the latest commit from hotfix/3.8-support and test again.

Cheers!

@P403n1x87 Success! hotfix/3.8-support seems to work. I tried both the austin and austin-tui and both worked. One note: I did need to run with sudo so perhaps worth a mention in the docs. Thanks for the quick fix!

I'm experiencing the same thing:

[I] ➜ python --version
Python 3.8.2
[I] ➜ python -c "import platform; print(platform.mac_ver())"
('10.15.4', ('', '', ''), 'x86_64')
[I] ➜ austin --version
austin 1.0.0
[I] ➜ austin -o a.out ./test.py
[I] ➜ lsa -lah a.out

Versions

• MacOS 10.15.4
• Python 3.8.2 (Anaconda)
• Austin 1.0.0

austin built from sources via:

git clone --depth=1 https://github.com/P403n1x87/austin.git
cd austin
gcc -O3 -Wall src/*.c -o src/austin

Thanks for reporting this issue. I just realised that the README lacks some important information about Austin on MacOS. There is a good chance that this issue is being caused by System Integrity Protection. If the Python executable you are using resides in /usr/bin, then even sudo won't help here, unless SIP is disabled. In order to avoid disabling SIP, the Python executable should live outside of /usr/bin (but the use of sudo is still required). Hence, if the executable is in /usr/bin, may I ask you to run Austin from, e.g. within a virtual environment please (with sudo)?

from austin.

I tried within a virtual env and using sudo, still same result. I am running in iTerm2 which already is set to "Full Disk Access" and "Developer Tools" in Settings | Security & Privacy.

[I] ➜ which python
/Users/rhet/opt/anaconda3/envs/osxphotos/bin/python
[I] ➜ sudo austin -o t.out ./test.py
[I] ➜ ls -lah t.out
-rw-r--r--@ 1 rhet  staff     0B May 14 07:51 t.out

from austin.

Sure, austin python test.py | echo still doesn't yield any output

austin-tui python test.py doesn't crash but still doesn't show any output:

Looking at the CMD output, it doesn't seem to use the python version I passed in when calling austin:

The same is true, if I call the executable explicitly: sudo austin-tui ./.venv/bin/python test.py

Thanks for the feedback. I will look into this as soon as I can.

Hi there.

I have prepared a PR with a fix for this issue. May I ask you to try checking out the branch hotfix/3.8-support and check that Austin now works as expected, please?

Thanks.

from austin.

I tried the hotfix on MacOS 10.15.4 but unfortunately still get the same results.
sudo austin /path/to/python t.py | echo yields no output
sudo austin -o t.out /path/to/python t.py runs but yields empty output file
and
sudo austin-tui /path/to/python t.py runs but yields no output exactly as @larsrinn reported earlier in this thread

Tried both anaconda python 3.7 and 3.8

from austin.

Excellent! Thanks for testing and sharing the results. I have added a note in the resend about SIP on macOS.
