"f(void)" is the correct and preferred form for a function taking no
argument, while some places use the older "f()". These were reported
by clang's -Wmissing-prototypes, for example:
src/cpuset.c:111:5: warning: no previous prototype for function 'ha_cpuset_size' [-Wmissing-prototypes]
int ha_cpuset_size()
include/haproxy/cpuset.h:42:5: note: this declaration is not a prototype; add 'void' to make it a prototype for a zero-parameter function
int ha_cpuset_size();
^
void
This aggregate patch fixes this for the following functions:
ha_backtrace_to_stderr(), ha_cpuset_size(), ha_panic(), ha_random64(),
ha_thread_dump_all_to_trash(), get_exec_path(), check_config_validity(),
mworker_child_nb(), mworker_cli_proxy_(create|stop)(),
mworker_cleantasks(), mworker_cleanlisteners(), mworker_ext_launch_all(),
mworker_reload(), mworker_(env|proc_list)_to_(proc_list|env)(),
mworker_(un|)block_signals(), proxy_adjust_all_maxconn(),
proxy_destroy_all_defaults(), get_tainted(),
pool_total_(allocated|used)(), thread_isolate(_full|)(),
thread(_sync|)_release(), thread_harmless_till_end(),
thread_cpu_mask_forced(), dequeue_all_listeners(), next_timer_expiry(),
wake_expired_tasks(), process_runnable_tasks(), init_acl(),
init_buffer(), (de|)init_log_buffers(), (de|)init_pollers(),
fork_poller(), pool_destroy_all(), pool_evict_from_local_caches(),
pool_total_failures(), dump_pools_to_trash(), cfg_run_diagnostics(),
tv_init_(process|thread)_date(), __signal_process_queue(),
deinit_signals(), haproxy_unblock_signals()
Only mworker uses proc_self, and it was declared in global.h, forcing
users of global.h to include mworker and its dependencies.
Moving it to mworker reduces the preprocessed size of version.c from
170 to 125kB by shrinking the number of local includes from 30 to 16
and the number of system includes from 147 to 132.
This function will be useful to check if the keyword is already registered.
Also add a define for the max number of args.
This will be needed by a next patch to fix a bug and will have to be
backported.
This one was not easy because it was embarking many includes with it,
which other files would automatically find. At least global.h, arg.h
and tools.h were identified. 93 total locations were identified, 8
additional includes had to be added.
In the rare files where it was possible to finalize the sorting of
includes by adjusting only one or two extra lines, it was done. But
all files would need to be rechecked and cleaned up now.
It was the last set of files in types/ and proto/ and these directories
must not be reused anymore.
Almost no change except moving the cli_kw struct definition after the
defines. Almost all users had both types&proto included, which is not
surprizing since this code is old and it used to be the norm a decade
ago. These places were cleaned.
