Sage 9.5.beta7 ?

[Emmanuel Charpentier]

A recent refresh of my Sahge tree gave me this :

charpent@zen-book-flip:/usr/local/sage-9$ sage --version
SageMath version 9.5.beta7, Release Date: 2021-11-18

But as far as I know, this version has been neither released nor announced…

What is this ?

I think the develop branch is regularly changing with new commits each
day (hopefully) as Volker merges positively reviewed tickets. You can
browse pages and pages of commits that came after 9.5.beta6 to the
develop branch here:

https://github.com/sagemath/sage/commits/develop

It looks like he committed a new 9.5.beta7 version 18 hours ago, but
just hasn't sent out an email yet. Presumably he always does a tagged
commit like this *before* he sends out an email, since it would be
annoying if he did that after sending out the announcement email.

FWIW, here is what I observe after this (possibly premature) upgrade :

On Debian testing running on core i7 + 16 GB RAM, upgrading 9.5.beta6(configured to use all available system packages) to 9.5.beta7 andrunning ptestlong results in a (transient) timeout and five permanent failures :

Doctest	Result	P/T
src/sage/rings/polynomial/polynomial_zmod_flint.pyx	Timed out	T
src/sage/interfaces/fricas.py	1 doctest failed	P
src/sage/rings/complex_arb.pyx	3 doctests failed	P
src/sage/functions/gamma.py	1 doctest failed	P
src/sage/symbolic/function.pyx	1 doctest failed	P
src/sage/rings/real_arb.pyx	12 doctests failed	P

The same failures (one format difference in fricas an a bunch of small numerical differences) have been reported for the upgrade of this machine to 9.5.beta5, but the numerical differences were not observed when upgrading another Debian testing to 9.5.beta5.

HTH,

Hi,

Regarding the release process, my understanding is Volker works

on a release branch in a different repo; once we see Sage 9.5.beta7 at

    https://github.com/sagemath/sage/tags

it can be considered as released. It sometimes takes the announcement

a few hours or a day to get posted by Volker after that; that step is not

automated.

After fetching that branch (with tags), one gets the list of merged tickets

(such as posted in Volker's announcement emails) from an appropriate

`git log` invocation:

    $ git fetch origin develop --tags -q

    $ git log --oneline --first-parent 9.5.beta6^...9.5.beta7

Building on two machines I observed the same failures

as reported by Emmanuel Charpentier, except the timeout

in `src/sage/rings/polynomial/polynomial_zmod_flint.pyx`.

I also got a few other failures, see details below along with

references to tickets fixing them.

On Debian 10 buster with FriCAS installed, I get the same

FriCAS doctest failure, which is already tracked at #32886.

On an Early 2014 13-inch MacBook Air, in macOS 10.14.6,

with many Homebrew packages, here is how things went.

No trouble in these preliminary steps:

```

$ git switch develop

$ git pull origin develop --tags -q

$ git branch -vv

* develop   cc60cfebc4 Updated SageMath version to 9.5.beta7

$ export MAKE='make -j5'

$ source .homebrew-build-env

$ ./bootstrap -q

```

Running configure gives an import error regarding lzma:

```

$ ./configure -q

Traceback (most recent call last):

  File "<string>", line 1, in <module>

ImportError: No module named lzma

```

This might have to do with

- #30948: build/pkgs: Split out spkg liblzma from xz

and maybe `build/pkgs/lzma/distro/homebrew.txt` needs adjusting.

Sage builds fine but there are doctest failures in 7 files:

```

$ make -s V=0 ptestlong

```

Random seed 264523619537841110147717491410595481298

was used and doctests failed in the following files:

- (a) src/sage/env.py  # 1 doctest failed

- (b) src/sage/lfunctions/pari.py  # 1 doctest failed

- (c) src/sage/functions/gamma.py  # 1 doctest failed

- (d) src/sage/rings/complex_arb.pyx  # 3 doctests failed

- (e) src/sage/rings/real_arb.pyx  # 12 doctests failed

- (f) src/sage/symbolic/function.pyx  # 1 doctest failed

- (g) src/sage/interfaces/expect.py  # 2 doctests failed

```

Total time for all tests: 11732.3 seconds

    cpu time: 25929.6 seconds

    cumulative wall time: 45148.8 seconds

Pytest is not installed, skip checking tests that rely on it.

make: *** [ptestlong] Error 1

```

All failures but (g) were reproduced with random seed 0.

- (a) was already reported at ticket:29024#comment:168,

      and has a proposed fix at #32880 (needs review)

- (b) already has a positively reviewed fix at #32797

- for (c-d-e-f): see proposed fix at #32905 (needs review)

Here is failure (g), in case it rings a bell for someone.

```

Hopefully the tickets mentioned above make it into Sage 9.5.beta8.

And maybe some more -- currently there are 23 positively reviewed

tickets with milestone sage-9.5:

https://trac.sagemath.org/query?milestone=sage-9.5&status=positive_review&group=priority&max=999&col=id&col=summary&col=component&col=time&col=changetime&col=author&col=reviewer&col=keywords&desc=1&order=changetime

and many more tickets with that milestone are at various

other stages of completion.  Lots to do!   --Samuel

I'm often starting the release/upload script before going to sleep at night, in those cases you'll see the announcement the next day or so. No worries though, if you see the code then its released!
