gmid v1.6 -- "Stargazers" (tags/v1.6)
move all sandbox-related code to sandbox.c
while there, add capsicum for the logger process
refactoring: imsg everywhere
use imsg to handle ALL kinds of IPC in gmid. This simplifies and shorten the code, and makes everything more uniform too.
handle SIGHUP gracefully
i.e. don't print scary messages with LOG_CRIT priority!
give each server process its own socket for the executor
this fixes a bug introduced with the prefork mechanics: every server process shared the same socket, and this would cause a race condition when multiple server processes asked for a script cgi being executed. This gives each server process its own socket to talk to the executor, so the race cannot happen.
fix various compilation errors
Include gmid.h as first header in every file, as it then includes config.h (that defines _GNU_SOURCE for instance). Fix also a warning about unsigned vs signed const char pointers in openssl.
refactor executor_main
now it's symmetrical to listener_main().
don't add the query to argv
FRC3875 says that if the query does not contain any unecnoded "=" characters, we SHOULD treat the query string as a "search-string", split in on "+" and add every word to the CGI argv. In launch_cgi it's too late because iri->query is the *decoded* query! I have in mind some refactoring around how we decode things, so this is postponed.
