C özel PHP uzantısı Segfault başlatmasını sınıf

0 Cevap php

Ben bir sınıf ile kendi PHP uzantısı geliştiriyorum. Geçenlerde Ubuntu 9.04 den 9.10 'a yükseltilmiş ve uzatma kırdı. O zamandan beri benim dev ortamı 10.04 ve orada gayet iyi çalışıyor gibi, onu giderir görmek için 10,04 güncellemek için çalıştı. Anlıyorum ne gelen tek önemli fark, sunucu 64 bit ve benim laptop 32 bit mimarisi olmasıdır. Ben PHP sürümü 5.3.2-1ubuntu4.5 (Zend build 20090626) var.

Ben benim test PHP dosyasını çalıştırarak denedim:

<?php
$server =  "http://localhost/";
$port = 1214;
$f = new PPKeyClient($server, $port);
var_dump($f);

Ve uzantısı ilgili bit:

PHP_MINIT_FUNCTION(pp)
{
        // Register PPKeyClient class
        zend_class_entry ce;
        INIT_CLASS_ENTRY(ce, "PPKeyClient", pp_functions);
        PPKeyClient_ce = zend_register_internal_class(&ce TSRMLS_CC);
        PPKeyClient_ce->create_object = PPKeyClient_object_new;
        memcpy(&PPKeyClient_handlers, zend_get_std_object_handlers(), sizeof(zend_object_handlers));
        PPKeyClient_handlers.clone_obj = NULL;
        return SUCCESS;
}

zend_object_value PPKeyClient_object_new(zend_class_entry *ce TSRMLS_DC)
{
        zend_object_value retval;
        PPKeyClient_object *intern;

        // TODO - only instantiate look at
        // http://stackoverflow.com/questions/1906565/php-extension-library-accessing-php-superglobals
        // or google for http://www.google.co.uk/search?hl=en&safe=off&q=superglobals+in+php+extensions&aq=f&aqi=&aql=&oq=&gs_rfai=

        intern = ecalloc(1, sizeof(PPKeyClient_object));
        zend_object_std_init(&(intern->std), ce TSRMLS_CC);
        zend_hash_copy(intern->std.properties, &ce->default_properties, (copy_ctor_func_t) zval_add_ref, NULL, sizeof(zval *));

        intern->last_curl_result = PPKC_NO_REQUEST;

        retval.handle = zend_objects_store_put(intern, PPKeyClient_object_dtor, NULL, NULL TSRMLS_CC);
        retval.handlers = &PPKeyClient_handlers;
        return retval;
}

PHP_METHOD(PPKeyClient, __construct)
{
        PPKeyClient_object *intern;
        char *url, *ssl_ca_crt = NULL;
        int port = 80, url_len, ssl_ca_crt_len = 0, ua_len = 0;

        if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|ls", &url, &url_len, &port, &ssl_ca_crt, &ssl_ca_crt_len) == SUCCES$
        {
                intern = (PPKeyClient_object*)zend_object_store_get_object(getThis() TSRMLS_CC);
//              intern->port = port;

//              intern->baseurl = estrndup(url, url_len);
//              intern->baseurl_len = url_len;
//              intern->ssl_ca_crt = estrndup(ssl_ca_crt, ssl_ca_crt_len);
//              intern->ssl_ca_crt_len = ssl_ca_crt_len;
//              intern->useragent = "PP KeyClient (PPExt#" PHP_PRIVATE_PASSWORDS_EXTNAME " v" PHP_PRIVATE_PASSWORDS_VERSION ")";
        }
}

Ben intern = (PPKeyClient_object*)zend_object_store_get_object... satırını yorumlama iş yapar biliyorum, ama açıkçası ben bu olmadan kurucusundan değerlerini ayarlanamaz.

Kayboldum ve herhangi bir yardıma kadar ne bulma seviniriz!
