Global HashTables & access violations

php 4.2.3 and 4.2.2 windows 2000 command line debugging I posted this a week ago, no replies yet... Ive written an extension to PHP that (among other things) uses a global HashTable object for a mini cache. I fill it, and then have a simple PHP function to pull a string out of the cache, and return it. However, I keep getting wierd internal access violations whenever I try to use it. In the sample code below, if I do this in test.php: $zendTest = idc_env("zendTest"); echo "zendTest: $zendTest\n"; And execute it, the value "this is a zend test" will be output to the screen, as well as everything after. My code executes fine... but at the very very last second I get an access violation when "zend_execute_scripts" tries to calculate "if(!retval)", because suddenly "retval" cannot be evaluated any more. Whaaa? Anyway, here's the relevant snippets of my C code: ======================= PHP_RINIT_FUNCTION(idc) { zval* val; char* key = "zendTest"; MAKE_STD_ZVAL(val); ZVAL_STRING(val, "this is a zend test", 1); // move to PHP_MINIT_FUNCTION after all bugs are out ALLOC_HASHTABLE(IDC_G(server_environment)); zend_hash_init(IDC_G(server_environment), 0, NULL, ZVAL_PTR_DTOR, 0); // run a test zend_hash_update(IDC_G(server_environment), key, strlen(key)+1,

    (void *)&val, sizeof(zval *), NULL);

return SUCCESS; } PHP_RSHUTDOWN_FUNCTION(idc) { // move to PHP_MSHUTDOWN_FUNCTION once all bugs are out zend_hash_destroy(IDC_G(server_environment)); FREE_HASHTABLE(IDC_G(server_environment)); return SUCCESS; } PHP_FUNCTION(idc_env) { HashTable *env = IDC_G(server_environment); zval **value = NULL; char *valueStr = NULL; int argc = ZEND_NUM_ARGS(); char *name = NULL; if (zend_parse_parameters(argc TSRMLS_CC, "s", &name) == FAILURE)

    return;

if (zend_hash_find(env, name, strlen(name) + 1, (void **) &value) == SUCCESS) {

    if ((*value)->type == IS_STRING)
    {
      valueStr = Z_STRVAL_PP(value);
      return_value->type = IS_STRING;
      return_value->value.str.len = Z_STRLEN_PP(value);
      return_value->value.str.val = estrdup(valueStr);
    }

} } ======================= Im assuming that Im not initializing (or destroying) something properly, but my code seems to be fairly correct, based on the other PHP extensions. In addition, if I move the code in RSTARTUP and RSHUTDOWN to MSTARTUP and MSHUTDOWN, I get a bunch of memory leaks that dont make any sense... the leaks are worse in php 4.2.3 than in 4.2.2. I have no clue why that would be. Any hints on the "right" way to use a HashTable or Zend object in C for a global PHP mini-cache would be greatly appreciated... -- Brian 'Bex' Huff bex@stellent.com Phone: 952-903-2023 Fax: 952-829-5424 **All Electronic Mail sent from the Stellent, Inc Electronic Communication Network is scanned by Antigen 7.0.**
