[BUG] obscured script can not run with cygwin python

[shaobo-zhang-senscomm]

Reproduced steps: generate scripts with “--platform windows.x86_64 --platform linux.x86_64 --platform darwin.x86_64” parameter.

Expected results: The obscured script can run in cygwin environment, cygwin python (not windows python).

Actual results: The obscured script can not run.

https://github.com/dashingsoft/pyarmor/discussions/1784 This is discussion. Is there any way to rebuild pyarmor_runtime.pyd for cygwin python?

[jondy]

Does it work to create link python39.dll in cygwin?

For example,

cd /usr/bin
# please make sure `libpython3.9.dll` exists, or it may be libpython3.9m.dll
ln -s libpython3.9.dll python39.dll

It will be solution for cygwin platform

[shaobo-zhang-senscomm]

hi @jondy, it can't work with "ln -s". libpython3.9.dll looks like a specific file for cygwin.

[jondy]

Could you show cygcheck /path/to/pyarmor_runtime.pyd after create the link?

[shaobo-zhang-senscomm]

shaobo.zhang@PC-SSZ060-1 /usr/bin
$ ln -s libpython3.9.dll python39.dll

shaobo.zhang@PC-SSZ060-1 /usr/bin
$ ls | grep python
libpython3.9.dll
python
python3
python3-config
python3.9-config
python3.9.exe
python39.dll

[jondy]

It seems it need rebuild the extensions for cygwin.

[shaobo-zhang-senscomm]

We can not rebuild python39.dll because it may need cygwin or python development environment. Could you rebuild pyarmor_runtime.pyd?

[jondy]

I'll rebuild pyarmor_runtime.pyd and pytransform3.pyd in this month

[jondy]

I have built dev extensions https://pyarmor.dashingsoft.com/downloads/temp/cygwin.x86_64/libs/cp3.9/pytransform3.dll https://pyarmor.dashingsoft.com/downloads/temp/cygwin.x86_64/libs/cp3.9/pyarmor_runtime.dll

Could you verify it work by cygwin python3.9:

python3.9
>>> import pytransform3

It seems my cygwin is too old to run python3.9, so I can't verify it

[shaobo-zhang-senscomm]

pytransform3 can import, but pyarmor_runtime can't import, Is that correct ?

[jondy]

import pyarmor_runtime directly will raise python exception, it's OK.

[jondy]

Fixed in 8.5.10

Now there is new package pyarmor.cli.core.cygwin to support Cygwin with Python 3.7~3.9 (cygwin official download site only provides Python 3.7~3.9 packages)

[shaobo-zhang-senscomm]

hi @jondy There is a cygwin_x86_64 folder under pyarmor_runtime_006272/py39. But the script does not use it, it still try to find pyarmor_runtime_006272.py39.windows_x86_64.

[jondy]

Try to apply this patch 425164dd836ef92bf0b3ab68958e69b034b8980e

[jondy]

I'll check it.

[shaobo-zhang-senscomm]

I have re-written pyarmor_runtime.dll, but it still failed

[jondy]

I build one dev extension pyarmor_runtime, please download it and overwrite the old one in the package pyarmor/cli/core/cygwin and try it

https://pyarmor.dashingsoft.com/downloads/temp/cygwin.x86_64/libs/cp3.9/pyarmor_runtime.dll

[shaobo-zhang-senscomm]

Hi @jondy, I put this pyarmor_runtime.dll into ~/miniconda3/envs/py39/lib/python3.9/site-packages/pyarmor/cli/core/cygwin/x86_64 (conda envs) and python -m pyarmor.cli -d gen, then license error. I try to register machine again. Register fail. What happen?

I upgrade pyarmor from 8.5.x t0 8.5.10. Will the machine id change while i run pyarmor reg -g 1 ?

[jondy]

Try to remove ~/.pyarmor/.license.token

[shaobo-zhang-senscomm]

it works now, thank you very much.
