It handles reading of configuration files internally and allows allows for a global configuration file. The design is so that it minimizes the work to replace the existing option parsing in gpg and friends by this one and to allow global configuration files for them. This is the just the basic code which should allow replacement of the parsers. A forthcoming patch will implement flags for options given in the global config file.

| | | | | | | | | | | | | | | | | | | | | | | | | | * src/init.c (emergency_cleanup_list): New gloabl var. (_gpgrt_add_emergency_cleanup): New. (_gpgrt_abort): New. Repalce all calls to abort by this. Also replace all assert by either log_assert or a stderr output followed by a _gpgrt_abort. (run_emergency_cleanup): New. * src/visibility.c (gpgrt_add_emergency_cleanup): New public API. (gpgrt_abort): New public API. -- Libgcrypt uses its own assert function which makes sure to terminate the secure memory. This is safe as log as an assert is triggered internally in Libgcrypt. GnuPG runs emergency cleanup handlers right before log_fatal etc to tell Libgcrypt to terminate the secure memory. With the move of the logging function to gpgrt in gnupg 2.3 this did not anymore. Thus we now provide a mechanism in gpgrt to do right that. Eventually Libgcrypt can also make use of this. What this does not handle are calls to abort or failed asserts in external libraries or in libc. We can't do anything about it in a library because a library may not setup signal handlers.
