211285 - void nsRuleNetwork::Init doesn't check the return value of PL_DHashTableInit

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[timeless]

This is a code inspection bug.

QA:
To verify that this bug is fixed, make sure that all callers in of 
PL_DHashTableInit in the indicated class/file check and handle a failure return 
result.
To verify that this bug is invalid, simply verify (e.g. with lxr) that 
PL_DHashTableInit is no longer used by the indicated class/file.

PL_DHashTableInit returns a PRBool indicating whether it succeeded. 
PL_DHashTableInit *can* fail. Code can not assume that table->ops or table-
>data will be null (in fact it probably will not be), although in all 
likelyhood table->entryStore will be null it probably isn't safe to assume this.

Code at time of bug filing:

 108 void
 109 nsRuleNetwork::Init()
 110 {
 111     mNextVariable = 0;
 112     PL_DHashTableInit(&mSymtab, &gOps, nsnull, sizeof(SymtabEntry), 
PL_DHASH_MIN_SIZE);
 113 }
