- Fixed memory leaks when a response is buffered and the buffer
- limit is reached or Privoxy is running out of memory.
- Commits bbd53f1010b and 4490d451f9b. OVE-20201118-0001.
- Sponsored by: Robert Klemme
+ Improve the handling of chunk-encoded responses by buffering the data
+ even if filters are disabled and properly keeping track of where the
+ various chunks are supposed to start and end. Previously Privoxy would
+ merely check the last bytes received to see if they looked like the
+ last-chunk. This failed to work if the last-chunk wasn't received in one
+ read and could also result in actual data being misdetected
+ as last-chunk.
+ Should fix: SF support request #1739.
+ Reported by: withoutname.
