MAINT: test with manylinux numpy/scipy pre-release

[matthew-brett]

Numpy / Scipy switching to daily manylinux wheels of trunk, instead of building
wheels specific to Ubuntu 12.04 for every commit. Use these new wheels
for numpy and scipy pre-release testing.

See: #15699, #15689 and scipy/scipy#7188.

oh this is nice. thanks @matthew-brett

[jreback]

maybe have the old URL re-direct?

[matthew-brett]

My first-pass plan was to find everyone who is using the old URL and update their configs to use the new ones - but it's not a bad idea to redirect....

[jreback]

and that URL is very odd......

@matthew-brett side questions.

• I would not be averse to doing similar wheels for pandas. how are you doing this now? (I assume using travis / circle ci cron?)
• do you know if anyone is building nightly conda packages? (and putting them somewhere)?

[jreback]

thanks @matthew-brett

[matthew-brett]

Daily wheels would be excellent! Yes, it's a travis cron job building on the daily branch of MacPython/numpy-wheels :

• https://travis-ci.org/MacPython/numpy-wheels/branches
• https://github.com/MacPython/numpy-wheels/tree/daily

so what needs to change here? https://github.com/MacPython/pandas-wheels

[matthew-brett]

Have a look at : https://github.com/MacPython/numpy-wheels/blob/master/.travis.yml . Note DAILY_COMMIT. In the daily branch we have - DAILY_COMMIT=master. Then it's just a question of setting up the cron job via the travis-ci interface : https://docs.travis-ci.com/user/cron-jobs/

[jreback]

ok we shall c. in theory it should work.

[jreback]

@matthew-brett how does DAILY_COMMIT get defined? (IOW by the cron on travis?)

[matthew-brett]

No, I defined DAILY_COMMIT in the daily branch, but another option would be to detect the cron job using something like:

if [ "$TRAVIS_EVENT_TYPE" == "cron" ]; then DAILY_COMMIT=master; fi

or similar.
