I think it may still be too early to discontinue manylinux1, sadly.

Systems requiring manylinux1 are those with:

pip < 19.0 (Jan 2019) [1]
Linux distribution older than around 2010 (glibc < 2.12) [2]

I did a PyPI BigQuery [3] just now, editing to give results for 32,
and 64 bit (by changing the manylinux wheel name matching regexp).

Then I processed a bit with Pandas [4].

It looks like about 34% of PyPI manylinux*_i686 downloads are for
systems that actually need manylinux1, and about 17% of
manylinux*_x86_64.  See the table in [4] for a listing of the top 10
entries.

Cheers,

Matthew

Note that a large fraction of that will be CI systems that get default
Ubuntu pip (18.1 mostly), and could be very easily updated just like we do
in our own CI (a simple `pip install -U pip`).

If you really want to get to a small percentage of pip <19.1, we can wait
for another 5 years. Which seems undesirable. While I agree that we can
keep manylinux1 around for a little longer (maybe another year or so?),
gating it on Linux distro pip version defaults would be odd. Pip is still
very immature; people with a several years old Pip would be well-served by
having to upgrade it.

Hi,

Updated for Numpy wheels only - BigQuery [1], Notebook [2].

41% of 32-bit wheels need manylinux1, 30% of 64-bit wheels.

Ralf - agreed we shouldn't wait too long for old pip - but maybe we
need to think of some way of reminding people with old pip to upgrade?

Cheers,

Matthew

Thanks for doing the analysis, very useful data.

I don't think there's much we can do unfortunately. That's up to Pip
itself, and it may have good reasons not to nag people to upgrade.

Cheers,
Ralf
