When launching footclient with -E,--client-environment the environment variables that should be set by foot, wasn't. Those variables are: * TERM * COLORTERM * PWD * SHELL and all variables defined by the user in the [environment] section in foot.ini. In the same way, we did not *unset* TERM_PROGRAM and TERM_PROGRAM_VERSION. This patch fixes it by "cloning" the custom environment, making it mutable, and then adding/removing the variables above from it. Instead of calling setenv()/unsetenv() directly, we add the wrapper functions add_to_env() and del_from_env(). When *not* using a custom environment, they simply call setenv()/unsetenv(). When we *are* using a custom environment, add_to_env() first loops all existing variables, looking for a match. If a match is found, it's updated with the new value. If it's not found, a new entry is added. del_from_env() loops all entries, and removes it when a match is found. If no match is found, nothing is done. The mutable environment is allocated on the heap, but never free:d. We don't need to free it, since it's only allocated after forking, in the child process. Closes #1568 |
