- 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.
+ Add missing client-body-tagger data to the action_type_info[] struct
+ so lookups based on the action index work correctly again.
+ Prevents assertion failures or segfaults when trying to edit
+ an action file with the CGI editor.
+ The type of failure depended on whether or not assertions
+ were enabled and on whether or not Privoxy had been compiled
+ with FEATURE_EXTERNAL_FILTERS.
+ Regression introduced in Privoxy 3.0.34.
+ Patch submitted by Aaron Li in #940.

- remove_chunked_transfer_coding(): Refuse to de-chunk invalid data

+ Bump MAX_FILTER_TYPES which should have been done in d128e6aa4
+ when introducing the client-body-tagger{} action.

- available to be read.

- or the other TLS backends don't seem to trigger the crash.

- socks5_connect(): Add support for target hosts specified as IPv4 address
- Previously the IP address was sent as domain.
+ Fix socks4 and socks4a support under glibc's source fortification.
+ With glibc's source fortification, gcc offers the compilation warning
+ resulting in a runtime abort() when using a socks4 or socks4a upstream proxy.
+ Despite the warning, the strlcpy() call in question is fine: gcc
+ misidentifies the size of the destination buffer, estimating to hold
+ only a single char while in fact the buffer stretches beyond the end of
+ the struct socks_op.
+ The issue was originally reported in the NixOS issue tracker at
+ https://github.com/NixOS/nixpkgs/issues/265654
+ prompted by an upgrade of glibc from 2.37-39 to 2.38-0.
+ Patch submitted by Ingo Blechschmid, joint work with

- Initialize ca-related defaults with strdup_or_die() so errors
