2018-10-08NTv1 grid shift: fix file offset for reading of shift values in ntv1_can.datEven Rouault
When investigating the format of NTv1 and comparing PROJ code with the actual header of ntv1_can.dat, I discovered that the longitude & latitude shift values started at offset 192, whereas PROJ assumed that the header was 176 bytes only. This caused PROJ to use the wrong offsets values (shift of one grid sample by longitude). So the effect was moderately visible, especially on the latitude, but when comparing with NTv2, one can see that the longitude value after the fix seems to closer to NTv2. old: echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022624 -100.50040292 0.00000000 inf new: echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022403 -100.50041841 0.00000000 inf echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=$HOME/proj/proj-datumgrid/north-america/ntv2_0.gsb +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022348 -100.50041978 0.00000000 inf old: $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096789 -70.89746834 0.00000000 inf new: $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096858 -70.89749190 0.00000000 inf $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=$HOME/proj/proj-datumgrid/north-america/ntv2_0.gsb +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096782 -70.89749276 0.00000000 inf

Make CTABLE V2 handling the same as CTABLE. The pj_log call hit a NULL pointer during fuzzing. Found with autofuzz.
2018-03-20Remove final \n from pj_log messages.Kurt Schwehr
There was a mix of pj_log calls with and without a trailing newline. pj_stderr_logger already adds a newline to the end of each msg, so pj_log calls don't need their own.

Functions should only be prefixed with 'pj_' when they can be used in other parts of the code base and not just within a single file. Takes care of the last step in #675.

2017-12-17Declare non-local variables as const where possibleAaron Puchert
Having non-const variables of static lifetime or even global scope is usually a bad idea. These variables are inherently constants, and this should be enforced. This required marking some functions as not modifying input parameters and marking some pointers as pointers to const. One advantage is that the compiler usually puts const static variables in a read-only code segment, so they can't be modified physically. This can be verified with `nm` (on POSIX systems). To avoid changes to the public API, functions returning non-const pointers to data tables were left intact, but the returned data may not be modified. Internally we prefer using the proj_list_* functions over the pj_get_*_ref functions, because the former return const pointers.
2017-11-27Replace some asserts by compile-time assertionsAaron Puchert
Decisions regarding the size of certain types are always made at compile time, hence this is where the assertion should take place. If the assertions fail, there is now a compiler error.
2017-10-20Handle allocation failure when loading grid files (#616)Aaron Puchert
* Handle allocation failure when loading grid files Continuing #606, we tackle the same issues in the loading and processing of grid files. This should fix potential crashes and memory leaks, and makes sure the global lock is always released. * Use pj_calloc when zero-initialized memory is wanted
2017-10-19Prevent crashes and leaks on allocation failure (#606)Aaron Puchert
* Prevent crashes and leaks on allocation failure Memory allocation can fail. We need to gracefully handle this case and prevent dereferencing null pointers. * Make NULL checks consistent within a file * Properly report allocation errors * Improve cleanup in pj_gc_reader.c * Implement pj_strdup and use instead of strdup The function strdup is not part of ANSI C 89, but a POSIX extension. Therefore we can not rely on it being available on all platforms.

2015-05-31Fix extraneous parentheses warning.Elliott Sales de Andrade
This warning indicates maybe we wanted to use assignment and added the extra parentheses to silence that *other* warning about assignment in a conditional. However, we really want a conditional, and the parentheses are due to it being in a macro, so using a yoda conditional avoids the ambiguity and silences the warning.
