Sage 9.0 released

[Volker Braun]

Just in time for the new decade, here is the first version of Sage running on Python 3 by default. Many thanks to everyone who contributed! 

The "master" git branch has been updated to Sage-9.0. 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

There was no change over 9.0.rc1

[Jaap Spies]

Congrats! And many thanks!

Wow! I would take the honour to be the second person to celebrate the release of Sage on Python 3 by default.

I thank the great people in the Sage developer community who made this!

A nice present for the new year!

[Eric Gourgoulhon]

Thank you very much Volker!

And congratulations to all people who made the Python 3 switch possible, especially to Frédéric Chapoton!

Happy New Year!

Eric.

[Nicolas M. Thiery]

Deep bow indeed to Frédéric for leading the Python 3 charge!

And to everyone else for making it possible.

And to Volker for yet another release management, right on time for
Python3's 2020 pledge :-)

Cheers,
Nicolas

Congratulations ! And atriple ban four the release manager, who managed to get a Python 3-base Sage just in time. Kudos...

Mandatory nitpick: the second decade of the 21ts century CE shall end on Dec 31, 2020 23:59:59. As it has already been noted, there is no year 0 in this calendar : the latter predates the introduction of the concept of a number zero ; furthermore, mathematics were not the forte of (most of) the ecclesiastics who created this calendar (they even managed to slip in an offset in the calendar : the historical events supposed to take place around the birth of the person identified as Jesus of Nazareth point this birth around 5 BC. Nice Irishism...).

This is probably the most common off-by-one (fencepost) error in all mathematics and programming. We are stuck with it ; we can at least try to be consistent...

+1, and thanks for all your hard work!

Just for the record: Built from a fresh clone of the develop tree, on two macOS systems: 10.13.6 (2017 iMac Pro, 18-core Xeon W) and 10.14.6 (2017 MBP, Quad-core Core i7). No problems with the build, and all tests (‘ptestlong’) passed on both systems!

Several people, including me on several machines, seem to have issues when building the R 3.6.2 package. See

https://twitter.com/ArtyHlr/status/1212726544021512197

This was already discussed in the thread of 9.0.rc1.

On my Ubuntu 19:10 (the last one!);  I could not upgrade to 9.0, due to this "R" problem.

So, I have deleted my sage tree (sniff) and cloned a fresh one. After that everything went ok. There should be dependence

problems with some libraries.

Just built conda packages for sage 9.0 and there's only 33 doctests failing down from 36 for 8.9.

Binaries are up now!

[John Cremona]

Building from source from scratch on ubuntu 16.04 I had a problem:

Error building Sage.

The following package(s) may have failed to build (not necessarily

during this run of 'make all-start'):

* package: python3-3.7.3.p1

  log file: /usr/local/sage/sage-9.0/logs/pkgs/python3-3.7.3.p1.log

  build directory: /usr/local/sage/sage-9.0/local/var/tmp/sage/build/python3-3.7.3.p1

(log attached).   The machines does have python3 installed system-wide.

I found the discussion at https://ask.sagemath.org/question/48276/building-sage-89-from-source-fails/  and installed libncurses5-dev, then tried ./sage -f python3 but it failed in the same way, so I am trying after make distclean; make configure; ./configure; make

Apologies now I see that some of the earlier thread on this topic was started by me with similar issues (on a different machine).  I just don't remember such things these days.  The sooner I can find someone else to be sysadmin for the 8 or so machines I look after the better!

The error at the end of the log:

ModuleNotFoundError: No module named 'readline'

meant Python was not able to build its readline module.

So, did something like the following solve the problem?

$ sudo apt-get install libncurses5-dev libreadline-dev
$ make ncurses-clean
$ make readline-clean
$ make configure
$ ./configure
$ make

[John Cremona]

Yes it did -- thanks.  In fact I did "make distclean" instead of the first two lines as I was in no hurry (and te machine has 32 cores but was otherwise idle).

I am still working on two of my (ubuntu 16 LTS) machines which managed to build sage's python3 without openssl support.  I had the relevant python2 wrapper packages installed but not the python 3 ones, so I installed those and started again, no luck so far but I'll track it down by comparing log files across machines.  (Not having ssl support means that sage -pip install fails, as everyone knows, but which is not deemed to be a fatal failure of prerequisites.)

Happy new year. Thank you very much Volker once again for the release. Thanks to all the people involved in the passage to Python3 including Frédéric Chapoton for the so many tickets he created, authored, reviewed to get Sage to work with Python 3.
