@ggnmstr thank you for the PR. I think everything is ok except of some trivial issues. The tests should be fixed - could you please try to run tests without healpix:

gmake USE_HEALPIX=0 install
gmake USE_HEALPIX=0 test

I would also ask to start the commit comment from capital lettet as it was done for other commits.

Do you mean the title of the pull request,@stepan-neretin7 ? The one commit message athttps://github.com/postgrespro/pgsphere/pull/43/commits does start with a capital letter.

Yes, I think it's a good idea. I also suggest that you also specify the issue number in the comment, so that he automatically linked it to the desired issue even before the merge.

To finalize PR the following changes are required:

Update pg_sphere--1.2.3--1.3.0.sql. Add command to create the implemented function.
Add new function description into Functions -> spoly functions section of the User Manual (gmake pdf).

@stepan-neretin7, this "return null" behavior is common among all functions, I don't think it is possible to change something just in place.

The default tab size on github is 8. It can be changes to 4 in Profile -> Settings -> Appearance -> Tab size... Not sure, how to change it for a specific repository and specific file type.

I changed it. For me it looks like this:

Add spaces afterDatum so thatspherepoly_is_convex lines up vertically with the names of the functions above this.

SELECT spoly_is_convex(NULL);
spoly_is_convex
(1 row)
why you return null? is this correct for interface?

I agree, it should return false. The third value is unnecessary. To fix it STRICT keyword should be removed in CREATE FUNCTION command. I also propose to update the tests by adding this case.

spherepoly_is_convex() functions seems to be ok as the first working version, but the code is not optimized. There are duplicate calculations in the for loop that can slowdown the performance.

Why did you add this blank line? I think it should be removed.

Take a look at the diff output at the bottom of the log here:
https://app.travis-ci.com/github/postgrespro/pgsphere/jobs/607714835

You need to change the line numbers in this file to match the results so that there are no differences.

@ggnmstr Thank you for your contribution. I plan to merge PR#40 first, your PR will be the next. I guess, new differences may appear - one more iteration may be required to fix the tests. It seems to be a problem of init_test that should be redesigned in the future.
