Trouble getting tests running

Open eclipseo opened this issue 2 years ago • 2 comments

Hello,

I can't seem to manage to get extractcode and typecode to run the tests.

The whole issue is that part of the README.rst:

To install this package with its full capability (where the binaries for 7zip and libarchive are installed), use the full extra option::

pip install extractcode[full]

If you want to use the version of binaries (possibly) provided by your operating system, use the minimal option::

pip install extractcode

In this case, you will need to provide a working and compatible libarchive and 7zip installed and configured in one of these ways such that ExtractCode can find them:

  • a typecode-libarchive and typecode-7z plugin: See the standard ones at https://github.com/nexB/scancode-plugins/tree/main/builtins These can either bundle a libarchive library, a 7z executable or expose a system-installed libraries. It does so by providing plugin entry points as scancode_location_provider for extractcode_libarchive that should point to a LocationProviderPlugin subclass with a get_locations() method that must return a mapping with this key:

    • 'extractcode.libarchive.dll': the absolute path to a libarchive shared object/DLL

    See for example:

    • https://github.com/nexB/scancode-plugins/blob/4da5fe8a5ab1c87b9b4af9e54d7ad60e289747f5/builtins/extractcode_libarchive-linux/setup.py#L40
    • https://github.com/nexB/scancode-plugins/blob/4da5fe8a5ab1c87b9b4af9e54d7ad60e289747f5/builtins/extractcode_libarchive-linux/src/extractcode_libarchive/init.py#L17

    And in the same way, the scancode_location_provider for extractcode_7zip should point to a LocationProviderPlugin subclass with a get_locations() method that must return a mapping with this key:

    • 'extractcode.sevenzip.exe': the absolute path to a 7zip executable

    See for example:

    • https://github.com/nexB/scancode-plugins/blob/4da5fe8a5ab1c87b9b4af9e54d7ad60e289747f5/builtins/extractcode_7z-linux/setup.py#L40
    • https://github.com/nexB/scancode-plugins/blob/4da5fe8a5ab1c87b9b4af9e54d7ad60e289747f5/builtins/extractcode_7z-linux/src/extractcode_7z/init.py#L18

  • use environment variables to point to installed binaries:

    • EXTRACTCODE_LIBARCHIVE_PATH: the absolute path to a libarchive DLL
    • EXTRACTCODE_7Z_PATH: the absolute path to a 7zip executable

  • a system-installed libarchive and 7zip executable available in the system PATH.

So I am on a distro with libarchive-3.7.1 and p7zip-16.02 installed. Obviously I don't want to bundle with the full option.

I set up:

export EXTRACTCODE_7Z_PATH=%{_bindir}
export EXTRACTCODE_LIBARCHIVE_PATH_ENVVAR=%{_libdir}
%pytest

It seems that libarchive is detected:

(same with libmagic)

However nothing works:

archive_read_new is not found so it doesn't find libarchive I believe.

So I may not have understood the README.rst correctly. Are all the part s following "In this case, you will need to provide a working and compatible libarchive and 7zip installed and configured in one of these ways such that ExtractCode can find them:" mandatory or do I have to choose among the options?

Are the plugins mandatory?

Then If I distribute extractool, does the user have to set up EXTRACTCODE_7Z_PATH and EXTRACTCODE_7Z_PATH each time? Is there a way to avoir that without bundling?

I have packaged the "system" plugins and it works now.

Awesome! You rock.

I am reopening this though as I still want to make sure we have some tests using the latest versions of these system packages !
