35 Fixed a violated invariant (leading to a crash) when
37 Fixed a possible crash in ClientFinish when a pipelined

39 Fixed a bug in handling of client-side Expect: 100-continue
40 (reported by Charley Chu).

42 issued in the order opposite to a client-side pipeline (many
43 thanks to Joachim Haga).
44 Abort when the config file couldn't be parsed (thanks to

70 Fix a race condition that could cause ``error message lost in
71 transit'' errors if a request was cancelled during connect.
72 Check for exitFlag in workToDo: faster reaction to signals.
74 28 March 2004: Polipo 0.9.2:

100 18 February 2004: Polipo 0.9:
101 Reworked the DNS code to parse ids even when a reply's qdcount
102 is 0. No longer falls back to gethostbyname when DNS server

107 Minor changes to work around Cygwin mis-design.

123 non-authorized client.
124 Implemented 100-continue, controlled by the variable expectContinue.
125 Implemented tristate, 4- and 5-state variables. Split
126 proxyOffline into proxyOffline and relaxTransparency. This is
127 an incompatible change to the config file format.
128 Cleaned up the handling of allowed port ranges. New
129 configuration variable allowedPorts (and new type intlist).
130 Implemented tunnelling through the CONNECT method (https
132 Will now read a request body on error (avoids a deadlock).
133 Reworked the PUT/POST code to read the reply eagerly rather
134 than waiting for the write to finish (avoids writing the full
135 body on error and avoids the same deadlock as above).
136 Made server addresses sticky: will now remember which of a
137 servers addresses worked last time, and use that address first.
139 16 january 2004: Polipo 0.8.99.1:
140 Fixed an expiry bug that caused DNS queries to be repeated on
142 Added the variable ``preciseExpiry'' that prevents trusting
143 the mtime during expiry.
145 14 January 2004: Polipo 0.8.99.0:
146 Implemented IP address-based authentication.
147 Implemented HTTP ``basic'' authentication.

149 makes the on-disk cache format incompatible with previous versions.
150 Made the number of server slots configurable.
151 Partially rewrote the disk cache code.
152 Fixed a file descriptor leak in the early error handling code.
153 Fixed a bug in the base64 encoder; this makes the on-disk cache
154 format incompatible with previous versions.

156 (100-Continue is not implemented yet).
157 Made the number of server slots configurable at runtime.

160 Log file is now line buffered.
161 Will reopen the log file on SIGUSR1 and SIGUSR2.

181 2 December 2003: Polipo 0.8.1:
183 Fix a possible crash when doing a POST on a busy server.
184 Fix a possible crash when socket(2) fails; implement switching
185 to a different address when socket(2) fails (e.g. when
186 accessing a double-stack host from an IPv4-only client).
187 Fix a problem with servers stuck in the ``probing'' state.
188 Work around a bug in Konqueror that strips question marks from
190 Fix incorrect error handling when dealing with connection
192 Fix a compile problem in dns.c.
193 Remove dependency on SSL, include MD5 code instead.
194 Fix signedness of s_maxage.
196 23 November 2003: Polipo 0.8:
198 IPv6 support, on both the client and server side, including
199 DNS support and RFC 2732.
200 Reworked the DNS code.
201 Made it possible to compile without any particular resolver
202 and without the on-disk cache.
203 Fixed a problem with the chunking encoder.
204 Made the config file parser grok octal and hex values, allowed
205 colons and tildes in unquoted strings.
206 Implemented tilde expansion in some config variables.
207 Made Polipo slightly less eager to honour range requests for
208 dynamic instances. Marked generated objects as dynamic. These
209 changes should solve some of the problems with PMM.
210 Implemented the If-Range header (on both the client and server
212 Implemented support for range requests smaller than one chunk
213 (and hence for pmmSize being smaller than CHUNK_SIZE).
214 Fixed a bug that caused a deadlock (until a server timeout)
215 when doing a POST/PUT request with no free connection slots.
216 Fixed a problem when diskCacheRoot didn't end in `/'.
217 Fixed a refcounting problem that could cause Polipo to crash
219 Fixed an alignment problem that could cause crashes on
220 architectures that don't like unaligned memory accesses
221 (thanks to Rob Byrnes).
222 Fixed a bug with the disk cache that caused spurious ``disk
223 entry changed behind our back'' warnings (and in principle
224 could cause data corruption, although that's very unlikely).
225 Made opening connections slightly less aggressive -- Polipo
226 would sometimes open two connections where only one was needed.
227 Modified client-side code to notice client shutdowns earlier
228 and notify the server side straight away.
230 7 October 2003: Polipo 0.7
232 Made the Request function a method of objects.
233 Fixed a bug that could sometimes cause data corruption.
234 Fixed a bug that could cause sending of incorrect data to
235 the client on a range request.
236 Fixed POST and PUT requests.
237 Fixed a bug that could sometimes cause a POST request to use a
239 Included code to do poor man's multiplexing.

241 Fixed a bug that could lead to idle connections dying without
243 Fixed probing for pipelining.
244 Actually use the new time function introduced in 0.5.
245 Fixed a bug in strcasecmp_n.
246 ForbiddenFile can now be a directory.
248 26 September 2003: Polipo 0.6
250 Fixed precondition handling.
251 Fixed a bug that could lead to lockups when revalidating an
254 27 June 2003: Polipo 0.5
256 Made the presence of a reader or writer explicit on the client
258 Reworked closing client connections.
259 Reworked reporting of server-side errors.
260 Made buffer allocation lazy; idle clients and servers no
261 longer use up buffers.
262 Reworked UTC time handling to use timegm(3) when available.
264 12 March 2003: Polipo 0.4
266 Implemented expiry of the on-disk cache.
267 Implemented reliable aborting of connections; Polipo should no
268 longer deadlock when a server falls into a black hole.
269 Changed direct reads to be more aggressive by using readv in
271 Changed serving of chunked data to be more eager about
272 serving a chunk's end marker.
273 Implemented better reporting of DNS errors.
274 Fixed a deadlock with pipelining on the client side.
275 Removed most of the remaining copies when reading on the
277 Fixed a bug that caused some headers to disappear in transit.
278 Fixed a possible livelock when reading chunked encoding.
279 Fixed an overflow when pipelining on the server side.
280 Fixed generation of indexes from the on-disk cache.
281 Fixed a DNS crash when falling back on gethostbyname.
283 1 March 2003: Polipo 0.3
285 Implemented retrying of timed-out DNS requests.
286 Implemented configuration mechanisms for case-insensitive
287 atoms, time values and atom lists; censoredHeaders can now be
289 No longer censors User-Agent. Blame Beppe and Alain.
290 Changed the handling of hop-by-hop HTTP headers to deal with
291 multiple Connection headers.
292 Made client-side errors and successful revalidation no longer
293 close the connection.
294 Fixed a bug that caused the allocation of an extraneous 2MB (!)
295 at startup. Polipo can run in 100KB once again.
296 Fixed a refcounting bug and some incorrect frees that could
297 lead to crashes when recovering from a server-side error.
298 Fixed a bug with POST/PUT that could trigger a failed assertion.
299 Made sure that POST/PUT don't get scheduled in multiple pieces.
301 17 February 2003: Polipo 0.2
303 Fixed an incorrect assertion that could cause crashes when the
305 Fixed (hopefully) logic for 304 replies.
306 Minor tweaks to scheduling that cause some speed increase when the
307 client is pipelining and the server is fast.
308 Minor bug fixes and cleanups.
309 Macro-ified do_log and friends.
311 3 February 2003: Polipo 0.1
313 Initial public release.
