This is a more appropriate place for the function, since it is more
related to tags than wheels, and will make it easier to refactor Wheel
into its own module.
This reduces the number of required arguments and helps establish a
convention for install_* functions, which should take a scheme instead
of the individual components.
* Add SHA256 hash of .whl as info output
Currently I'm trying to debug some issues with what appear to be
corrupt wheels. It would be very useful to see what pip thought the
state of things was as it wrote the wheel output; if a final corrupt
distributed file is then different to what pip has saved in its build
logs, you know the problem is somewhere after pip but before
distribution.
Currently we get a log of the initial creation, then the stamp when it
gets moved in the final output location, e.g.:
creating '/tmp/pip-wheel-71CpBe/foo-1.2.3-py2.py3-none-any.whl
...
Stored in directory: /opt/wheel/workspace
A lot happens in between this, so my suggestion is we add the final
output file and it's hash before the "Stored in directory:", e.g. you
now see:
Building wheels for collected packages: simple
Running setup.py bdist_wheel for simple: started
Running setup.py bdist_wheel for simple: finished with status 'done'
Finished: simple-3.0-py3-none-any.whl sha256=39005a57a6327972575072af82e11d0817439fe6a069381f6f2a123a8c0bf1cf
Stored in directory: /tmp/pytest-of-iwienand/pytest-18/test_pip_wheel_success0/workspace/scratch
Successfully built simple
Despite the hash being fairly important for things like
--require-hashes, AFAICS the final hash is not put in the logs at all
currently, so I think this is generically helpful.
* Reword wheel hash details output
This rewords the output to be more like the form of the preceding
messages. Additionally the size is added, since we have calculated it
anyway. The output will now look like:
Collecting simple==3.0
Building wheels for collected packages: simple
Building wheel for simple (setup.py): started
Building wheel for simple (setup.py): finished with status 'done'
Created wheel for simple: filename=simple-3.0-py3-none-any.whl size=1138 sha256=2a980a802c9d38a24d29aded2dc2df2b080e58370902e5fdf950090ff67aec10
Stored in directory: /tmp/pytest-of-iwienand/pytest-0/test_pip_wheel_success0/workspace/scratch
