SymPy 0.7.6 release candidate 2

[Aaron Meurer]

I have uploaded a second release candidate for SymPy 0.7.6. Please download and test it. You can find it at https://github.com/sympy/sympy/releases/tag/sympy-0.7.6.rc2. 

Please report any issues that you find, or if you find no issues, please report that you tested it.  Assuming there are no major issues I will do the final release within a week. 

The release notes for this release are at
https://github.com/sympy/sympy/wiki/release-notes-for-0.7.6. If you
see anything that is missing from that page, please add it.

I ran this through my Octave toolbox test suite. I think I found one
regression (`-oo < p` not evaluating to True where p positive, even
with simplify).

I filed as:

https://github.com/sympy/sympy/issues/8449

Looks like fixed in master. This is probably one of my or
@skirpichev's changes.

best,
Colin

Just running the test suite straight work just fine (as expected):

$ cd sympy-0.7.6.rc2/
$ python setup.py test
/.../
ALL EXAMPLES PASSED

$ python --version
Python 2.7.6
$ uname -a
Linux hera 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/issue
Ubuntu 14.04.1 LTS \n \l

I also tried it with some experimental packages of mine and no surprises there. All good!
Thanks for your hard work!

[Aaron Meurer]

We'll need to wait on the next release on that, as we are already on rc2, so I'd like to only get absolutely critical fixes in before 0.7.6 final. Technically the unevaluated result is not wrong, and your code will likely need to handle such cases anyway.

Thank you for testing this.

No problem, as you say its not critical. The only other change I
noticed from doing this is in Codegen, but its also not wrong so not
critical either, filed #8452.

Thanks for everyone for testing this. I haven't heard of any issues so I will do the final release tomorrow. If anyone else was planning on testing this, please do so now.

Thanks, I am running tests now, I'll report once they finish.

Here are the results:

https://gist.github.com/certik/cdafc1d7915c4492725a

Only the autowrap failures are there. The exception should not look
like this. If it can't compile it or there is some other problem, it
should say so in a clear manner.

[Aaron Meurer]

The decode() call should probably be decode('utf-8').

Are we sure that our benchmarks work:
 https://github.com/sympy/sympy/pull/8361#issuecomment-62064249
?

[Aaron Meurer]

I fixed one issue. The ones in benchmarks are run just by running the scripts.

The rest I ran with 

from __future__ import print_function

def benchit(m):

    mod, name = m.rsplit('.', 1);b = getattr(__import__(mod, fromlist=[name]), name)

    for f in dir(b):

        if f.startswith('bench') or f.startswith('timeit'):

            print(f, b)

            getattr(b, f)()

benchit('sympy.core.benchmarks.bench_arit')

benchit('sympy.core.benchmarks.bench_assumptions')

benchit('sympy.core.benchmarks.bench_basic')

benchit('sympy.core.benchmarks.bench_expand')

benchit('sympy.core.benchmarks.bench_numbers')

benchit('sympy.core.benchmarks.bench_sympify')

benchit('sympy.functions.elementary.benchmarks.bench_exp')

benchit('sympy.functions.special.benchmarks.bench_special')

benchit('sympy.integrals.benchmarks.bench_integrate')

benchit('sympy.integrals.benchmarks.bench_trigintegrate')

benchit('sympy.matrices.benchmarks.bench_matrix')

benchit('sympy.polys.benchmarks.bench_galoispolys')

benchit('sympy.polys.benchmarks.bench_groebnertools')

benchit('sympy.polys.benchmarks.bench_solvers')

benchit('sympy.series.benchmarks.bench_limit')

benchit('sympy.solvers.benchmarks.bench_solvers')

There was one issue (some calls to sort(), which I have deleted).
