Note that 0.15.1 is around the corner, but it's not as big of a jump.

Would 0.15.1 require additional changes to Sage?

Oh, did you tell Robert?

Minor comment: spkg-install is not executable (I know it is made executable upon building, but better fix this in the spkg anyway).

Why is the directory tests missing from the Cython source? This should either be fixed, or be documented.
comment:17 Changed 3 years ago by jdemeyer
What should be done with:
cdef mpz_t denom mpz_init_set_si(denom, 1)
This code is correct but gives a local variable 'denom' referenced before assignment warning.
(there are many of these in sage/matrix/misc.pyx for example)

comment:19 Changed 3 years ago by jdemeyer
This new Cython really gives a lot more warnings than the old one, in many cases for code which is perfectly fine. For me, this isn't really a problem, but it is certainly annoying.

I've fixed the executable bit on spkg-install and added the tests to the spkg. (I remember someone complaining way back that they were too big, but I don't think it's an issue and we've regularly shipped them before, and it's easier to just have them there.) The spkg at the above link has been refreshed.
The warnings are primarily due to the fact that mpz_t et al are declared as void* rather than arrays of size 1. http://hg.sagemath.org/sage-main/file/2a2abbcad325/sage/libs/gmp/types.pxd#l1 Once this is fixed the warnings should go away (and they are correct with respect to the current declarations). All the other warnings I've noticed are correct too, I simply haven't had the time to fix/update Sage's code.
Your review patch looks fine. You obviously looked at this, is the window closed for 4.7.2?

Your review patch looks fine.
In fact, it doesn't. I removed one line too much, fixed now.

This will certainly not be merged in sage-4.7.2.

If there is an easy way to fix this, then we should do this. I'm saying we should fix every single warning but if it is possible to declare mpz_t such that there are no warnings, we should certainly do this.
comment:23 Changed 3 years ago by jdemeyer
Of course, that should have been "I'm not saying we should fix every single warning"

One more thing: changing permissions is a change which should be committed. So could you please do a hg commit and re-upload the spkg? Otherwise, the package and patch looks good.

Yes, I agree these warnings should be fixed. #11992 .

Looks you forgot to update the spkg, it is exactly the same as before (last modified on 1 november):

Never mind, I will make the change.

Oops, I put it at

That's what comes of getting too little sleep. Go ahead and use that one (or if you've already done the trivial change, even better.)

comment:32 Changed 3 years ago by fbissey
Sorry to be late to the party. I get an error building the optional mpc extension in 4.8.alpha2 and I suspect cython-0.15.1 is the problem
sage/rings/complex_mpc.c: In function '__pyx_pf_4sage_5rings_11complex_mpc_15MPComplexNumber_16__float__': sage/rings/complex_mpc.c:9720:48: error: cast specifies array type
I am guessing the complex_mpc.pyx code needs to be updated but I don't really know how.
Replying to robertwb:
Yeah!
