2022-02-19Fix nullptr dereference in utilities whan argv[0] == NULLEven Rouault
https://lwn.net/Articles/?offset=50 was an entertaining reading where we learn that the fact that argv[0] contains the name of the binary is purely a convention, normally taken by the shell that launches the process, but not guaranteed by the execve() system call that does the job. The following test program tested against cct, cs2cs, geod, gie and proj make them cause a null pointer dereference ``` #include <unistd.h> #include <stdio.h> extern char **environ; int main() { char* argv[] = { NULL }; printf("%d\n", execve("/path/to/some/proj/binary", argv, environ)); return 0; } ```
2021-09-08createOperations(): deal with spherical planetocentric geodetic CRSEven Rouault
This also fixes conversion between geocentric latlong and geodetic latlong with cs2cs. This was dealt with in PR 1093, but in the wrong direction (the geocentric latitude must be <= in absolute value to the geodetic one) The issue here was linked to the semantics of the +geoc specifier, which affects the semantics of the input coordinates in the forward direction (+geoc means that the input coordinate is is a geocentric latitude), which defeats the logic of doing A to B by using the inverse path of A and the forward path of B.

result as soon as it is produced This is needed when working with pipes, when stdout is not an interactive terminal, and thus the behaviour is to have it buffered as a regular file, whereas with an interactive terminal, each newline character causes an implicit flush.

2019-03-24Doc: consistently use +opt and bracketsChris Mayo
+opt represents one parameter. An ellipsis indicates additional instances of the previous parameter may be given. Spaces are used between parameters and before an ellipsis, not purely to format brackets. See man(1) SYNOPSIS conventions.
2019-03-24Make cs2cs support 4D coordinates.Kristian Evers
This is a bit of a hack, 4D coordinates *will* be written to STDOUT but the output format speficied with -f is not respected for the t component, rather it is forward verbatim from the input. Fixes #1354
