Sage 8.2.rc2 released

[Volker Braun]

As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

Built from a fresh clone/update of the develop branch on macOS 10.11.6 (Quad-core Core i7) w/o problems, and all tests (‘testing’) passed!

On Ubuntu 16.04 x86_64 Xeon E5-2623 + 16 GB RAM, from a fresh git clone + pull develop, parallel (-j16) build OK and make ptestlong passed except for a single transient error to due to "Jmol failed to create file", as usual on this computer (race error?). The doctest is passed when run standalone.

That's weird about jmol--I haven't seen that, but I don't think the
Linux machine I do most builds on has a Java runtime installed so of
course I wouldn't see it. I should try to reproduce that at some
point if I can...

Looks fine on Windows but still needs this critical patch for the
tests before release:

[Erik Bray]

Didn't mean to send. Still needs these patches for Windows:

https://trac.sagemath.org/ticket/25137

[Dima Pasechnik]

#25118 has a fix for the OSX issue on #25113, it would be great to get it in (and so clang default on OSX).

[Emmanuel Charpentier]

FWIW, 8.2rc2 +  Trac#24585 + Trac#24969  builds and passes ptestlong without any failure whatsoever on Debian testing running on core i7 + 16 GB RAM.

HTH,

On macOS 10.10.5 (aka "Yosemite"), with Homebrew installed,

after renaming /usr/local and /opt/local so they don't interfere,

building Sage 8.2.rc2 succeeds.

However, trying to install jupyterlab via pip does not work:

    $ sage --pip install jupyterlab

    Collecting jupyterlab

      Could not fetch URL https://pypi.python.org/simple/jupyterlab/:

      There was a problem confirming the ssl certificate: [SSL:

      TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version

      (_ssl.c:661) - skipping

      Could not find a version that satisfies the requirement

      jupyterlab (from versions: )

    No matching distribution found for jupyterlab

​(while it worked fine with Sage 8.2.rc1).

Does anyone else observe that too?

[Samuel Lelièvre]

A quick web search reveals this:

- StackOverflow question:

  https://stackoverflow.com/q/49748063

- Answer by original poster to above question:

  https://stackoverflow.com/a/49748494

So I will try the upgrade to pip 9.0.3 which is part of

- Sage trac ticket #25051: Add DESTDIR support to additional

  Python packages; upgrade pip to latest patch release

  https://trac.sagemath.org/ticket/25051

[Samuel Lelièvre]

Upgrading to pip 9.0.3 allowed me to "sage --pip install" stuff.
I made #25051 a blocker. I hope it can be part of the next
release candidate, and eventually of the Sage 8.2 release.

On linux sage 8.1 jupylab install perfect.

But as I have a problem with my sage in user location (without sudo)

I do sage -sh

and then pip install jupyterlab upgrade (normal installation)

That's weird about jmol--I haven't seen that, but I don't think the
Linux machine I do most builds on has a Java runtime installed so of
course I wouldn't see it.  I should try to reproduce that at some
point if I can...

A few more data points:
- these Jmol errors are random (they don't appear in the same files each time I run make ptestlong, i.e. at each new develop release).
- I don't have them in my other Ubuntu 16.04 computer: both computers have the same software settings, they only differ by the CPU: Xeon E5-2623 vs. Core i7-6700HQ
- on the faulty computer (the Xeon one), these Jmol errors started to show up only after a certain Sage release (I don't remember which one but I may dig into messages on this list to find it).

Best wishes,

Eric.
