Remap ENOMEM from PROJ_ERR_INVALID_OP to PROJ_ERR_OTHER

2020-12-15T16:53:29+00:00

Revise error codes to have a reduced set exposed in the public API.

2020-12-15T00:13:43+00:00

Fixes #2482

And also add proj_context_errno_string()

Revise gie 'expect failure errno XXXX' strings

Remove old pj_ memory (de)allocation functions

2020-11-20T15:40:40+00:00

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary
function as API memory functions in proj_api.h is no longer there and
the other use as a workaround for old errno problems is no longer valid
either.

Replaced with malloc and free across the codebase.

Polar stereographic at pole: make it return (0,0)

2020-11-11T23:05:31+00:00

Due to the improved accuracy of pj_tsfn(), it no longer returns
0 when phi=90° due to the conversion in radians.
Some GDAL tests are very sensitive to the pole transforming to (0,0)
exactly, so add a special case for that.

utm/ups: make sure to set errno to PJD_ERR_ELLIPSOID_USE_REQUIRED if es==0

2020-03-10T17:01:43+00:00

ENOMEM was wrongly set after setting PJD_ERR_ELLIPSOID_USE_REQUIRED

Note: it is a bit strange to forbid the pure spherical case whereas the
maths would allow it. I presume this is due to the typical usage of those
methods.

src/projections/: remove assignments in expression and multiple statements per line

2020-03-08T18:58:35+00:00

Should hopefully result in no change in results, and hopefully more
readable code...

Various fixes/workarounds to make cppcheck 1.72 (Ubuntu 16.04) and HEAD/1.90dev happy (fixes #1648)

2019-10-28T08:03:10+00:00

Delete proj_math.h. Replace includes by ; we'll see if anyone

2019-09-18T20:29:35+00:00

needs .  Update scripts/reference_exported_symbols.txt and
src/proj_symbol_rename.h.

Prefix inverse and forward functions by their projection names

2019-04-26T16:18:30+00:00

This is mostly to have better OSSFuzz report. Currently a lot
of bug summaries are like
`proj4/standard_fuzzer: Divide-by-zero in s_inverse`

By prefixing the projection name, we will get better reports, like
`Divide-by-zero in airy_s_inverse`

This also makes it slightly easier to set a breakpoint by
function name.

stere: avoid division by zero
