1268387 - [Static Analysis][Resource leak] In function nsHttpChannel::ForceCacheEntryValidFor

Status: RESOLVED FIXED

(Core :: Networking, defect)

Description

[Andi [:andi]]

The Static Analysis tool Coverity added that ToNewCString(key) leaks memory in: 

    } else {
        mCacheEntry->ForceValidFor(aSecondsToTheFuture);

        nsAutoCString key;
        mCacheEntry->GetKey(key);

        LOG(("nsHttpChannel::ForceCacheEntryValidFor successfully forced valid "
             "entry with key %s for %d seconds. [this=%p]", ToNewCString(key),
             aSecondsToTheFuture, this));
    }

This should be fixed by freeing the memory allocated by ToNewCString(key).

Can't we just use key.get() instead of allocating?
