[sage-release] Re: Sage 8.2.beta8 released

[John H Palmieri]

I'm curious: why is the 8.2.beta8 tarball so much smaller than previous 
versions? (According to http://files.sagemath.org/devel/index.html, 
8.2beta8 is about 530MB, while 8.2.beta7 was just under 600MB.)

Depends how you count. The summarny at Openhub

https://www.openhub.net/p/sage

says it took an estimated 172 years of effort!

This is according to an analysis using the Constructive Cost Model,
also known as COCOMO.

Yes, but why does the `sage -f libpng` was not forced since it was 
necessary? I am not an expert at all on this, but from my point of view, it 
is like if there was problem with dependencies of giac.

Sorry if was unclear. I was using 8.2.beta2. I git pulled the 8.2.beta8 
from github. Then, I ran make ptestlong (first attempt) which finished with 
the error with giac. Then, I retried `make` again just to see (second 
attempt) and it again finished with the error with giac. Then, I googled 
the error. Then I did `sage -i libpng && make ptestlong` (third attempt) 
which finished with All tests passed as I reported the second time.

same OS all attempts.

No, because I hate to reinstall all my optional packages. So I use `make 
distclean` only if I am very forced to.

BTW, do you know a way to define all desired optional packages that I want 
to be installed during the make? Something like INSTALL_CCACHE=yes but for 
each optional packages?

Ok, but still strange to me.

Yes--two different objects, each with their own __mpz_struct values,
but the same _mp_d.  It's not too surprising that this can happen
considering how fast_tp_new assigns to this directly.  But it's not
immediately obvious to me how the code is incorrect either.

Hah!  Yes, I was extremely confused as to why Sage was telling me I
had a field with one element.

It's hard to say, because this bug is so subtle that any changes to
that code might make it -appear- to go away, unless I could find a
more exact way to reproduce it.  I well certainly look at the changes
that ticket proposes, but first it would be good to confirm where the
exact bug is (and, perhaps, why I'm only seeing it on Cygwin, which
may be coincidence...)

You really mean two different Integer objects with the same _mp_d (as 
opposed to the same Integer object being used mistakenly in two 
different places).

But what does exactly "first attempt" mean here? The one after upgrading 
the OS?
(and you did not do "make distclean" or did not start a fresh build some 
other way?)
This won't be a surprise, and won't be a bug...

Yes that particular one has been seen in the wild before. For some reason
the libpng install got broken and you are missing libpng.so inside sage.
Then the linker tries a system version and if it is not libpng-1.4+ you’ll
get that error because the symbol doesn’t exist before that version.
I would be good to figure out why some install don’t have libpng.so
though, that’s a bit of a mystery.

I see now--less likely a bug with MPIR/GMP itself, and more likely a
bug with Sage's fast_tp_new stuff for Integer.  I haven't looked too
closely at how it works yet, but in case anyone wants to take a look
there appears to be a bug where two Integers' mpz_t structs' _mp_d
member (the array of limbs) is being set to the same memory address.
They still have different mpz_t's, but since the limb array is being
shared the latter integer being initialized overrides the former.  It
seems to just happen rarely so it's to reproduce, and I just *happen*
to have found a case where it does happen pretty reliably...

I'm going home now, but that's the general synopsis if anyone wants to
take a further look at it.  I'll open a ticket tomorrow.

Well, I've been trying to debug this for a last hour and it got pretty
deep pretty fast.  I'm looking now at the possibility of a memory

[sage-release] Re: Sage 8.2.beta8 released

[Sébastien Labbé]

On Ubuntu 16.04, my first attempt at running make finishes with a problem 
with giac (undefined reference to `png_set_longjmp_fn')

The log finishes with:

...

I did 

sage -f libpng && make

which seems to have fixed the error:

...
[giac-1.4.9.45.p2] successfully installed.
...

... still running.

It would be good to have a final review on #21828, as OpenSuSE systems
still fail doctests and so cannot participate as patchbots.
