Note that the code does not only use a pre-processor generator for
defining the print functions, but also for their prototypes. Sadly, this
generated a conflict in mboxscan.c which this patch resolves, too.
* minimise core code hooks
* drop useless exporting of private functions (and make them static)
* reorder functions in eve.c so no prototypes are needed
* drop massive header include and add double include barrier in eve.h
While testing, I found two already existing bugs:
* the variable 'a' passed to iconv_convert() needs to be passed by
reference in order to allow for the desired side effect.
* Somehow the trailing junk after an iconv_conversion to a shorter
string messes things up (and gets printed!). I couldn't exactly find
out why this happens, but setting (*p) = 0; solves this problem.
-d was broken because fork-to-background was done after the update thread creation, so the
threads ended up in the wrong process. This delays the thread creation until after the fork.
Originally, I was experiencing sporadic lockups when reading inotify_fd;
which is strange, since it is protected by select(). This should fix it
despite of the original problem.
Besides improving performance when updating stuff, we ideally have no
text object specific code in update_stuff() anymore (aside some
leftovers).
The macros in construct_text_object() have gotten a bit crazier than
they were before:
* using CALLBACK(&func) instead of an INFO_* parameter to OBJ() will
make it add the given callback to the list of callbacks to be iterated
over at each update interval.
* BEWARE: the above assumes function pointer values to be > 0!
* This implicitly fixes a bug in the code: passing 0 as INFO_* value
led to selecting INFO_MAIL (1 << 0 == 1).
* Now it would select INFO_CPU (== 0), which got unused and therefore is
not a problem at all (the 0 value should be unused in enums anyway).
This needs some more work, then we should be able to drop the whole
INFO_* enum. Then CALLBACK() can die again and with it goes the ugly
casting stuff done to distinguish callbacks from INFO_* values.
