Segfault testing pyarmor 3.8.10 on Banana PI

[jondy]

I'm trying the last version of pyarmor (3.8.10) on Banana PI 3.4.113-sun8i #18 SMP PREEMPT armv7l

I downloaded _pytransform.so from http://pyarmor.dashingsoft.com/downloads/platforms/bananapi/_pytransform.so

When I test pyarmor 3.8.10 with the examples queens, I got the following output:

root@tlbox-13:/usr/src/pyarmor-3.8.10/src# pyarmor obfuscate 
--src=examples/simple --entry=queens.py "*.py" 
INFO     Obfuscate scripts in path "examples/simple" ... 
INFO     Obfuscate scripts with mode 8 
INFO     Save obfuscated scripts to "dist"

INFO     Make runtime files 
INFO     Update entry script dist/queens.py 
INFO     Obfuscate 1 scripts OK. 

Unfortunately, when I test the cypher code, I got a Segfault error.

root@tlbox-13:/usr/src/pyarmor-3.8.10/src/dist# python queens.py Segmentation fault

I also have tested pyarmor 3.8.10 with other versions of _pytransform.so you had sent me several months ago, and which were working, but now the result is the same: Segfault.

I would appreciate any clue you could give me in order to solve this issue.

[jondy]

In the core file you sent to me, I found python interpreter is "/usr/bin/python-dbg".

If Py_TRACE_REFS or Py_DEBUG is defined when building python interpreter, pyarmor won't work.

So could you try a non-debug version of python to run pyarmor.py?

[netman73]

I have disabled the use of python-dbg and now it obfuscates the example code, but unfortunately I still have an error when I run the script.

Any ideas?

[jondy]

Run obfuscated script with -d, it will print more error messages:

cd dist
python -d queens.py

[netman73]

I'm sorry, I don't see any diference.

Generally, if the python version used to obfuscate script is different from the python version to run obfuscated scripts, it will report MemoryError. But in this case it seems python version is same.

I'll build a temporary version to trace the detail in the log file.

Download this temporary version to /usr/src/pyarmor/src http://pyarmor.dashingsoft.com/downloads/platforms/bananapi/temp/_pytransform.so md5sum: 4763582eda013a6558e90bc3764b74c4

Then run the following commands

python pyarmor.py obfuscate --src=examples/simple --entry=queens.py "*.py"

cd dist
python queens.py

Send me the following files (base path is /usr/src/pyarmor/src):

• test_data.co
• _pytransform.log
• dist/queens.py
• dist/test_data.co
• dist/_pytransform.log

I need to check the output of each step to find why marshal loads failed.

[netman73]

Here are you are. requested_files.tar.gz

[jondy]

I check the files, the reason maybe is that the cached file examples/simple/.pyarmor_capsule.zip caused this problem. When you first created this file, the license is a trial license. Later, you replaced the trial license with your normal license file. But examples/simple/.pyarmor_capsule.zip is still old, and the trial license in capsule is transfered to dist. So the solution is

  cd /usr/src/pyarmor/src
  rm examples/simple/.pyarmor_capsule.zip

  python pyarmor.py obfuscate --src=examples/simple --entry=queens.py "*.py"
  cd dist
  python queens.py

If it works, then pyarmor3.8.10 should work on Banana PI with non-debug version of python.

If it doesn't work, send me all the files as before, I hope it will not happen, :)

How about clone a refresh pyarmor from github, for example

mkdir -p /usr/another
cd /usr/another
git clone https://github.com/dashingsoft/pyarmor.git
cd pyarmor/src
wget http://pyarmor.dashingsoft.com/downloads/platforms/bananapi/temp/_pytransform.so

python pyarmor.py obfuscate --src=examples/simple --entry=queens.py "*.py"
cd dist
python queens.py

[netman73]

It worked!
