Subject: Summary: BUGFIX: httpStateData leaks.
X-Git-Tag: SQUID_3_0_PRE1~47
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9a91f4b1f26742bbbfbdcc0dab2231801db1847b;p=thirdparty%2Fsquid.git

Summary: BUGFIX: httpStateData leaks.
Keywords:

CommRead's operator= was leaking cbdatareferences when assigning to an already extant object.
Fixed. We could benefit by generalising the algorithm for refcounting classes further - to allow the reuse of RefCount's logic with classes owning CBDATA - like CommRead.
