When trying to log an error in a custom httpd module, that error message is lost when logging in directive parsing code. I can see the error being written out through strace, but the error is not written to a log file:
Here is a sample module:
#include <httpd.h> #include <http_config.h> #include <http_log.h> const char * intoTheVoid(cmd_parms *parms, void *config, const char *args) { void * pass = NULL; apr_pool_userdata_get( & pass, "key", parms->server->process->pool ); ap_log_error(APLOG_MARK, APLOG_WARNING, NULL, NULL, APLOGNO(11111), "Test: foobar"); if (NULL == pass) { apr_pool_userdata_set((void *) 0x1, "key", NULL, parms->server->process->pool); } else { return "A second pass error."; } return NULL; } static const command_rec itv_directives[] = { AP_INIT_NO_ARGS( "IntoTheVoid", intoTheVoid, NULL, ACCESS_CONF | RSRC_CONF, "intothevoid description" ), { NULL } }; AP_DECLARE_MODULE( intothevoid ) = { STANDARD20_MODULE_STUFF, NULL, NULL, NULL, NULL, itv_directives, NULL };
