LRN's big logging rewrite (#1805):
* GNUNET_BOTTOM_LOGLEVEL and GNUNET_TOP_LOGLEVEL set global levels Use bottom level to force logging to be more verbose than configured Use top level to force logging to be less verbose than configured Obviously, bottom <= top * GNUNET_LOG sets per-component levels GNUNET_LOG looks like this: name[/bottom[/top]]/... name starts with a non-digit character, must not include '/' bottom and top must consist only of digits, or be empty a description is only used if it matches the component exactly as a special exception (for now) the name '*' matches any component per-component loglevels override global loglevels global levels override whatever is given via arguments or in config Examples: test_client/8/8/ run test_client with DEBUG level (usually leads to a timeout, by the way) */2/2/core/8/8/transport/4/4 run everything with WARNING, core - with DEBUG, transport - with INFO *//1/peerinfo/4/ run everything with top loglevel ERROR, global/configured bottom loglevel, and peerinfo - with bottom loglevel INFO and global/configured top loglevel statistics/ does nothing * Added GNUNET_ERROR_TYPE_UNSPECIFIED enum value, to hold -1. Its corresponding string is NULL. * Changed the logger calls as Grothoff suggested - to use static int to hold the result of runtime evaluation of logability. Logging can be unconditionally disabled in advance by defining GNUNET_LOG_CALL_STATUS to 0, and enabled in advance by defining it to 1. * Added GNUNET_CULL_LOGGING, which, if defined, completely culls out all logging calls at compile time. * Log definition parsing is only done once, results are cached. * Changed definition format, now it looks like this: [component|*|];[file|*|];[function|*|];[from_line[-to_line]];level/[component...] All field separators are mandatory (but some fields could be empty or be '*'). Line definition must be either empty or "number" or "number-number" Level definition must not be empty, and is a string representation of the level (i.e. DEBUG, WARNING, INFO, etc). Definition entry must end with a slash, whether or not there's another entry after it. File name is matched to the end of __FILE__, which allows file name to match not only the base name, but also directories leading to it. * Removed default WARNING loglevel from program and service utility code. Now they default to NULL (UNSPECIFIED) level, which can be overriden by GNUNET_LOG definition, if no level is specified via config or commandline. Log levels from config or commandline are overriden by GNUNET_FORCE_LOG. If GNUNET_*LOG are undefined, and no levels came from config or commandline, logger internally defaults to WARNING level. Add --enable-logging configure option
