*) mod_watchdog: add assertions to cleanup code

2022-02-25T13:18:51+00:00

  *) core/mpm_preform: do not invoke the fancy new child_stopping/stopped
     hooks when invoked from a signal handler. This is a stopgap to some
     strange behaviour in need of some deeper insight.

*) mod_watchdog: do not call a watchdog instance for

     AP_WATCHDOG_STATE_STOPPING outside its thread, as
     watchdog instances are not prepared to be invoked
     concurrently.

core: Efficient ap_thread_current() when apr_thread_local() is missing.

2022-01-25T17:34:57+00:00

#define ap_thread_create, ap_thread_current_create and ap_thread_current to
their apr-1.8+ equivalent if available, or implement them using the compiler's
thread_local mechanism if available, or finally provide stubs otherwise.

#define AP_HAS_THREAD_LOCAL to 1 in the two former case or 0 otherwise, while
AP_THREAD_LOCAL is defined to the compiler's keyword iff AP_HAS_THREAD_LOCAL.

Replace all apr_thread_create() calls with ap_thread_create() so that httpd
threads can use ap_thread_current()'s pool data as Thread Local Storage.

Bump MMN minor.

* include/httpd.h():
  Define AP_HAS_THREAD_LOCAL, AP_THREAD_LOCAL (eventually), ap_thread_create(),
  ap_thread_current_create() and ap_thread_current().
  
* server/util.c:
  Implement ap_thread_create(), ap_thread_current_create() and
  ap_thread_current() when APR < 1.8.

* modules/core/mod_watchdog.c, modules/http2/h2_workers.c,
    modules/ssl/mod_ssl_ct.c:
  Use ap_thread_create() instead of apr_thread_create.

* server/main.c:
  Use AP_HAS_THREAD_LOCAL and ap_thread_current_create instead of APR's.

* server/util_pcre.c:
  Use AP_HAS_THREAD_LOCAL and ap_thread_current instead of APR's.

* server/mpm/event/event.c, server/mpm/worker/worker.c,
    server/mpm/prefork/prefork.c:
  Use ap_thread_create() instead of apr_thread_create.
  Create an apr_thread_t/ap_thread_current() for the main chaild thread usable
  at child_init().
  
* server/mpm/winnt/child.c:
  Use ap_thread_create() instead of CreateThread().
  Create an apr_thread_t/ap_thread_current() for the main chaild thread usable

don't try to load modules from a NULL path

2020-07-31T01:21:25+00:00

ap_server_root_relative() can fail if apr_filepath_merge fails,
which can happen with a "bad" drive/volume or who knows what 
else on Windows. Regardless, if !fullname we are already
going to retry wih what was actually passed.

mod_watchdog: use a single "wd_running" pool in wd_worker() thread.

2020-04-17T17:15:51+00:00

Clear the pool where appropriate instead of multiple create/destroy.

  r1876599 where a destroyed pool was reused.  Rename the "ctx"
  variable to reflect its purpose.  Also tweak the pool tags.
