Re: Share data between apache modules

[Eugene Teslenko]

mod_a handler function returns "declined" both times it's being called.
Here is the source of mod's

===== mod_a.c =====

module AP_MODULE_DECLARE_DATA mod_a;

static int handler(request_rec *r) {
  // if (strcmp(r->handler, "fastcgi-script")) return DECLINED;
  apr_table_set(r->notes, "test-var", "test-string");
  ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, "mod_a[%d]: r_pp=%pp,
handler=%s", getpid(), r, r->handler);
  return DECLINED;
};

static void register_hooks(apr_pool_t *p) {
  static const char * const asz_before[]={ "mod_fastcgi.c", NULL };
  ap_hook_handler(handler, NULL, asz_before, APR_HOOK_MIDDLE);
}

module AP_MODULE_DECLARE_DATA a_module = {
  STANDARD20_MODULE_STUFF,
  NULL,
  NULL,
  NULL,
  NULL,
  NULL,
  register_hooks
};

===== mod_b.c =====

module AP_MODULE_DECLARE_DATA mod_b;

static int log_transaction(request_rec *r) {
  ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, "mod_b[%d]: test-var=%s,
r_pp=%pp, handler=%s", getpid(), apr_table_get(r->notes, "test-var"), r,
r->handler);
  return DECLINED;
}

static void register_hooks(apr_pool_t *p) {
  static const char * const asz_after[]={ "mod_a.c", NULL };
  static const char * const asz_before[]={ "mod_log_config.c", NULL };
  ap_hook_log_transaction(log_transaction, asz_after, asz_before,
APR_HOOK_MIDDLE);
}

module AP_MODULE_DECLARE_DATA b_module = {
  STANDARD20_MODULE_STUFF,
  NULL,
  NULL,
  NULL,
  NULL,
  NULL,
  register_hooks
};

Different pointers in the log:
