If this check is only used to decide to build the python-cffi/notmuch2
bindings, then yes.

I've been long thinking whether our current python3 check is "strict"
enough, as it, in configure, is:

if "$python" -c 'import sys; assert sys.version_info >= (3,0)' > /dev/null 2>&1

Perhaps that should be updated to (3,5) ?

In tox.ini the earliest version is 3.5 and if memory serves me right
there's a reasonably good reason for that.  I think the notmuch2
bindings use some features not yet present in 3.4.  But anything >= 3.5
should be supported and if not a bug.  I guess tox.ini should be updated
with 3.8 sometime :)

Given how long ago the old Python bindings were written, I can wait a
bit longer for the improved version. ;-) Still, I am looking forward to
the next Notmuch release.

Sorry about that. That's another reason for me to get a release out the
door soon.

Alas, there are no release archives available yet which contain the new
bindings. I was hoping to add Python 3.8 support for the Gentoo Linux
package I maintain, but our ebuilds rely on tagged releases of the
packaged software.

the old (modulename = notmuch) bindings actually do have memory
management issues with python > 3.6 (maybe also with 3.6). The new
bindings (modulename= notmuch2) should work with any python recent
3.x. They still have a few rough edges afaiu, but definitely new
projects should target the new bindings.

Python 3.x bindings support which versions, exactly?

2020-05-24 Thread Ralph Seichter
Hello,

having examined the source code, I assume that Notmuch's Python bindings
should support Python 3.x for any given 'x'. However, reading the Travis
logs at https://travis-ci.org/notmuch/notmuch and .travis.yml, the CI
tests apparently run on Ubuntu 18.04 and use only Python 3.6.

While I hope there won't be any problems with Python 3.7, 3.8 and 3.9,
I wanted to ask here first if anybody has tested this yet?
