Dotaz: php fastcgi neloguje chyby

[masi]

Ahoj,

provozuji 2 webservery s php prez fastcgi na debianu, jeden je na stare 6 a druhy na "nove" 7. Oboje funguje ok az na drobnost. V nove verzi debianu, kde mam tu samou konfiguraci (lisi se pouze verze balicku) se neloguji, ani jinak nezobrazuji php chyby. zkusil jsem v patricnem php.ini nastavovat logovani do souboru i do syslogu, zkusil jsem to i zakomentovat, aby se logovalo do error logu apache, zkusil jsem menit nastaveni fastcgi.logging a porad se nic neloguje. v zaveru jsem si zkusil jeste pustit vse rucne prez sekvenci:

deb7 ~$ PHPRC=/etc/php5/cgi/php.ini
deb7 ~$ PHP_FCGI_CHILDREN=2
deb7 ~$ export PHP_FCGI_CHILDREN
deb7 ~$ PHP_FCGI_MAX_REQUESTS=1000
deb7 ~$ export PHP_FCGI_MAX_REQUESTS
deb7 ~$ /usr/bin/php5-cgi /home/karel/public/www/info.php
Content-type: text/html


deb7 ~$


deb6 ~$ /usr/bin/php5-cgi /home/karel/public/www/info.php
PHP Fatal error:  Call to undefined function neplatny_nazev_funkce() in /home/karel/public/www/info.php on line 3
Content-type: text/html


Fatal error: Call to undefined function neplatny_nazev_funkce() in /home/karel/public/www/info.php on line 3

deb6 ~$

a na starem deb6 se vypsali chyby co sem zamerne napsal a na novem deb7 jen prazdna html stranka (viz vypis vyse).

Nepotkal se nekdo s timto problemem? Znate reseni, nebo je jiz nahlasen bug? Ja bezne pouzivam mod-itk, cili php prez fcgi moc neznam, cili bych rekl, ze je chyba v me konfiguraci, ale jinde mi to funguje. A google mi neporadil nic co sem uz nezkusil.

Predem diky za rady

Odpovědi

Čus,

Já když jsem debugoval chyby, co měli zákazníci na hostingu, tak jako nejlepší se vždycky ukázalo otevřít si jejich skript, a hned na začátek si nacpat display_errors a error_reporting (musím uznat, že někdy bylo opravdu šeredný vidět, kolik warningů jejich stránky vyhazujou i když fungují správně :D; holt někoho prostě baví programovat jako prase). Takže zkus php5-cgi předhodit něco jako toto:

<?php
ini_set( "display_errors", true );
ini_set( "error_reporting", E_ALL );

asd();

Vím, že to už vlastně v php.ini máš, ale ta možnost že php5-cgi si prostě čte jiné php.ini, nebo máš někde zatoulané nějaké ini_set(), je vždycky možná. Pokud by se ti ani při tomhle skriptu neobjevila chybovka, tak je něco naprosto brutálně špatně .

Pokud se ukáže, že chybovku s tímhle skriptem vidíš, tak bych začal u

<?php
php_config();

Tam někde bude zakopaný pes.

Zkontroluj, jestli editujes spravne php.ini.
