Re: [sage-devel] Re: singular crash

I would rather suspect pexpect for being flaky, than a Singular bug.

Are these system (i.e. non-SPKG) installs of Singular? We're accepting
anything newer than v4.1.0, but if some particular version is buggy we
should exclude it.

Besides, in the use case we're taking about, ./configure produces
results which are
wrong for the purposes of the further use, which is not to build any
packages, but only sagelib.
Let's stop this confusion - I suppose then the ugly pip commands can
be replaces by "make build", no?

No, if we use  autotools/make to build a project, there should be
meaningful make targets for testing too, force
people to learn peculiarities of tox or whatever the latest Python
testing rage is, is wrong.

 hmm, by design, or in error, "make ptest" starts building all the
 dependencies, e.g. maxima.
 So that's not a usual environment - perhaps it should be mentioned.

No, we should revise the documentation so that it does not advertise "make

that's not nice. Should we have a ./configure option that just blesses all

Yes, if one is not using the Sage distribution for build, one should also 
not use it for testing.
Use "sage -t".

[sage-devel] prime_pi gives wrong output

[Martin Zeman]

Hello,

prime_pi(281474961965055) gives correct output 8731188419994.

prime_pi(281474961965056)  gives wrong result 8731188419993.

Please note that second input is greater than first, however it produces 
smaller number of primes. The second output is obviously wrong.  

It was tested on CoCalc.com free trial and the bug is easily reproducible.

Should I open the ticket? Is it a known error?

Thanks

Martin Zeman

[sage-devel] singular crash

Dear all,

I just set up a patchbot but two tests related to singular fail. The
singular it uses was compiled from source. See the patchbot report
at https://patchbot.sagemath.org/ticket/32859/

sage -t --long --warn-long 42.4 
--random-seed=24651699140802493978117085271929917492 
src/sage/interfaces/expect.py

**
File "src/sage/interfaces/expect.py", line 915, in 
sage.interfaces.expect.Expect._eval_line

Failed example:
singular.interrupt()
Expected:
True
Got:
False
**
File "src/sage/interfaces/expect.py", line 921, in 
sage.interfaces.expect.Expect._eval_line

Failed example:
singular('2+3')
Expected:

1 item had failures:

Yes, I tested them on macOS Big Sur.

Re: [sage-devel] is coersion always tried in conversion code?

[David Roe]

I'm not following the discussion on that ticket completely, but it's hard
to see a situation where there'd be a speed benefit to trying coercion
first.  Here's why:

Given two parents A and B, if you try to convert an element of A into B
Sage computes and stores a convert map.  However, in order to ensure that
this convert map is reasonable, the first thing it tries when computing it
is to compute the coerce map instead. If that succeeds, it just stores and
returns that.  So the computation of a coercion map is built in to the
computation of a conversion.

This is a one-time cost for each pair of parents.  Afterward, when you try
to convert an element, it looks that map up in a hash table and applies
it.  Depending on the implementation of the map, you can get speedups by
improving how it computes its image.  You can also get speedups if you're
doing a loop of some kind by ensuring that you call the map only once
rather than many times (e.g. setting one=RBF(1) outside the loop rather
than adding the python int 1 each time).  But I doubt that explicitly
calling coercion before conversion will help.

Of course, the coercion system is complicated and I could be wrong.
Benchmarking is the actual arbiter.

[sage-devel] is coersion always tried in conversion code?

[Dima Pasechnik]

This came up on https://trac.sagemath.org/ticket/32851
- is there any speed benefit to explicitly try to do coersion before
trying conversion?

Thanks
Dima

Thanks - are these tested?

I've changed the release version at the bottom, so that it does not look 
like something untouched since Sage 9.2
