| Sticky Revision: |
Bringing environ back in sync with glexec: - new function int cgul_unsetenv_dst() needed to remove an entry from an 'saved' environment.
Adding const predicate to variable to prevent compiler warning.
- new function cgul_add_src_pattern() to add substring pattern entries from a src environment to a target environment. E.g. for GLEXEC_ variables into the target process environment. - reworked related cgul_add_src_list(), so that it is more or less consistent internally consistent with the new cgul_add_src_pattern()
Bringing environ back in sync with version in gLExec.
- don't change const char * parameter, so put it in a buffer..
- introduced cgul_ prefix for environ - synchronized two proxy writing functions, thereby fixing a const char* writing issue (segfault).
- Use properly size_t when needed
- introducing env_t (char **): now use &dst for creation/updating of environments instead of return value of functions. This makes it easier to have a few additions in a row etc. - make sure when input whitelist and/or src is null everything works as expected: new environment should be created and initialized to empty, old environment should be left unchanged. - make sure environ.h is effectively included once using a #ifndef
- added new function setenv_dst() adding a name, value pair to the dst environment, similar to add_namevalue() - check explicitly that whitelists aren't NULL, which lead to a segfault...
We're not in 2004... Changed year to 2010
No copyright text for us, only EGEE allowed (instructions from Francesco).
- Added a getenv for 'external' environments - no more pointer arithmetics...
- fixed a few initialization (valgrind) problems. - updated comments: remarks on strdup/putenv etc.
- added a number of new functions to:
add single pairs to external environment,
put some general stuff in special functions,
- Fixed a few memory leaks, probably none left (-:
- strarrlen returns NULL when argument is NULL (not just when list is empty). This is convenient...
environ.c / environ.h Provides methods to safely backup the environment, to clear the current environment and to re-set certain parts from the backup into it.
