bool ACLFilledChecklist::destinationDomainChecked ( ) const
allow_t const & ACLChecklist::fastCheck ( )
inherited

Perform a blocking (immediate) check for a list of allow/deny rules. Each rule comes with a list of ACLs.

The first rule where all ACLs match wins. If there is such a rule, the result becomes that rule keyword (ACCESS_ALLOWED or ACCESS_DENIED).

If there are rules but all ACL lists mismatch, an implicit rule is used Its result is the negation of the keyword of the last seen rule.

Some ACLs may stop the check prematurely by setting an exceptional check result (e.g., ACCESS_AUTH_REQUIRED) instead of declaring a match or mismatch.

Some ACLs may require an async lookup which is prohibited by this method. In this case, the exceptional check result of ACCESS_DUNNO is immediately returned.

If there are no rules to check at all, the result becomes ACCESS_DUNNO.

allow_t const & ACLChecklist::fastCheck ( const Acl::Tree list)
inherited

Perform a blocking (immediate) check whether a list of ACLs matches. This method is meant to be used with squid.conf ACL-driven options that lack allow/deny keywords and are tested one ACL list at a time. Whether the checks for other occurrences of the same option continue after this call is up to the caller and option semantics.

If all ACLs match, the result becomes ACCESS_ALLOWED.

If all ACLs mismatch, the result becomes ACCESS_DENIED.

Some ACLs may stop the check prematurely by setting an exceptional check result (e.g., ACCESS_AUTH_REQUIRED) instead of declaring a match or mismatch.

Some ACLs may require an async lookup which is prohibited by this method. In this case, the exceptional check result of ACCESS_DUNNO is immediately returned.

If there are no ACLs to check at all, the result becomes ACCESS_ALLOWED.

void ACLChecklist::nonBlockingCheck ( ACLCB callback_,
void *  callback_data_ 
)
inherited

Start a non-blocking (async) check for a list of allow/deny rules. Each rule comes with a list of ACLs.

The callback specified will be called with the result of the check.

The first rule where all ACLs match wins. If there is such a rule, the result becomes that rule keyword (ACCESS_ALLOWED or ACCESS_DENIED).

If there are rules but all ACL lists mismatch, an implicit rule is used. Its result is the negation of the keyword of the last seen rule.

Some ACLs may stop the check prematurely by setting an exceptional check result (e.g., ACCESS_AUTH_REQUIRED) instead of declaring a match or mismatch.

If there are no rules to check at all, the result becomes ACCESS_DUNNO. Calling this method with no rules to check wastes a lot of CPU cycles and will result in a DBG_CRITICAL debugging message.

Kick off a non-blocking (slow) ACL access list test

NP: this should probably be made Async now.

The ACL List should NEVER be NULL when calling this method. Always caller should check for NULL and handle appropriate to its needs first. We cannot select a sensible default for all callers here.
