upgrade to pynac-0.3.5

[rwst]

We skip 0.3.3 (#18155) which couldn't be used because of a bug showing on OSX.

* fixed the series expansion of zeta(s) around 1
* print_latex of wildcards
* clear the libtool versioning scheme
* sync with current GiNaC as much as possible
* revert GiNaC commit interfering with Pynac print order
* fix code that produced warnings

Upgrade will require a few doctests to adapt, see https://groups.google.com/d/topic/sage-devel/hwQXxFmutcU/discussion

On it, currently doing some more doctesting on Arch Linux (kernel 3.19.3-3, i7, 12GB RAM); will be finished soon.

Meanwhile: I can confirm that the bug with the unstable output of integrate(sec(x), (x, 0, pi/8)) on OSX (see pynac/pynac#18) is gone. Thanks to Volker for access to the OSX buildslave!

MAKE="make -j4" make ptestlong gives

The doctest fails with

This happened two times. However, when testing the respective file manually:

sage -t --long --warn-long 81.8 src/sage/combinat/dyck_word.py
    [574 tests, 0.95 s]
----------------------------------------------------------------------
All tests passed!
----------------------------------------------------------------------

So this only seems to occur for make ptestlong.

Additionally, as I've not run make ptestlong on a clean install of 6.7.beta1 yet, I'm not even sure if this is related to Pynac at all. I'll do so and report back...

See https://groups.google.com/forum/?fromgroups=#!topic/sage-devel/7BQPmEgfA8M -- until this is resolved, I can't review the new Pynac version reliably.

I had the same doctest fail today on a clean 6.7beta1 install and, just like you, could not reproduce it when running this specific test again on the file, so I doubt that this is related to this ticket.

I'm also quite sure that it has nothing to do with this ticket; especially after Vincent confirmed that this is happening for him too on both 6.7.beta0 and 6.7.beta1. This discussion, however, belongs to the sage-devel thread.

Still, I don't like the idea of giving this positive_review when I don't have a passing ptestlong, regardless of why the doctest is failing. Currently, I'm compiling sage on two more machines; one of those should enable me to review this.

It seems that something went wrong when I upgraded sage from 6.6.rc2 to 6.7.beta1. Completely rebuilding sage resolves everything, and make ptestlong passes without problems again for both, the clean install as well as this ticket (on all three machines I tested this; 2x Arch Linux, 1x Linux Mint). Therefore: positive_review. :-)
