Introduction
------------
When multiple wheels depend on each other and share some ``.so`` files,
it is possible to rely on ``auditwheel --exclude`` to make sure the ``.so``
is included in only one of the wheels to avoid duplicating the file in every package.
That allows Python wheels to share the same ``.so`` as far as at least one of them
is loading them in memory. See https://github.com/pypa/auditwheel/issues/76 and
https://github.com/pypa/auditwheel/pull/368 for discussions on the topic.
The problem with this approach is that the package where the ``.so`` is included
will have the library name mangled by ``auditwheel``, while the ones where it's
excluded will reference to the library with its original name.
Suppose you have ``libone.whl`` and ``libtwo.whl`` both depending on ``libfoo.so``,
and ``libone`` is a dependency of ``libtwo`` so you already know you can include
``libfoo.so`` only in ``libone.whl``, you could do::
auditwheel repair dist/libone.whl
auditwheel repair dist/libtwo.whl --exclude libfoo.so
In such case you would end up with the following wheels::
venv/lib/python3.10/site-packages/libone
├── __init__.py
├── _libone.cpython-310-aarch64-linux-gnu.so
venv/lib/python3.10/site-packages/libone.libs
└── libfoo-ef63151d.so
venv/lib/python3.10/site-packages/libtwo
├── __init__.py
├── _libtwo.cpython-310-aarch64-linux-gnu.so
The problem would be that while ``_libone.cpython-310-aarch64-linux-gnu.so``
was patched by ``auditwheel`` to know about the ``libfoo-ef63151d.so`` name,
``_libtwo.cpython-310-aarch64-linux-gnu.so`` was not, and so still refers to the
original name::
$ ldd venv/lib/python3.10/site-packages/libone/_libone.cpython-310-aarch64-linux-gnu.so
libfoo-ef63151d.so => ../libone.libs/libfoo-ef63151d.so (0x0000ffff8f8f0000)
$ ldd venv/lib/python3.10/site-packages/libtwo/_libtwo.cpython-310-aarch64-linux-gnu.so
libfoo.so => not found
Which means that trying to import ``libtwo`` will fail with::
ImportError: libfoo.so: cannot open shared object file: No such file or directory
Which makes sense, because we actually provided ``libfoo-ef63151d.so`` and not ``libfoo.so``.
To solve this problem ``consolidatewheels`` will patch all provided wheels to make sure that they
share a single naming convention for libraries that were mangled.
After ``consolidatewheels`` is used, the final result would be::
$ ldd venv/lib/python3.10/site-packages/libone/_libone.cpython-310-aarch64-linux-gnu.so
libfoo-ef63151d.so => ../libone.libs/libfoo-ef63151d.so (0x0000ffff8f8f0000)
$ ldd venv/lib/python3.10/site-packages/libtwo/_libtwo.cpython-310-aarch64-linux-gnu.so
libfoo-ef63151d.so => not found
which would work correctly as far as ``libone`` is imported _before_ ``libtwo`` as they will
both look for ``libfoo-ef63151d.so`` which was loaded already by ``libone``.
OSX Support
~~~~~~~~~~~
``consolidatewheels`` works also in conjunction with ``delocate``, consolidating all libraries
embedded by ``delocate`` and removing duplicates of the embedded libraries when they are provided
in multiple wheels.
Install
-------
Install with::
$ pip install consolidatewheels
Note that ``consolidatewheels`` requires ``patchelf`` to be available in the system,
and it only works on ``Linux`` systems. But those are the same requirements that
``auditwheel`` has, so you are probably already satisfying them if you use ``auditwheel``.
Usage
-----
Usage instructions::
consolidatewheels --help
Example::
consolidatewheels libone.whl libtwo.whl --dest=./consolidated_wheels
For a more complex example and a testing environment, you can take
a look at https://github.com/amol-/wheeldeps which uses ``consolidatewheels``
