strtables.c ziproxylogtool.c:
Minor tweaking in the hash-generation functions, to
reduce the likehood of hash collisions.
globaldefs.h ziproxylogtool.c:
Added GCC-specific optimizations to ziproxylogtool,
giving between 5%-15% speedup.
Such optimizations are innocuous to other compilers.
log.* cfgfile.* globaldefs.h gzpipe.c http.c netd.c
tosmarking.* ziproxy.c:
Fixed logging bug which added trash to HTTP output (bug
introduced in 2.7.9_BETA2).
Added more daemon error messages to error_log.
Several changes and code cleanup in debug_log.
Access log code rewritten from scratch and simplified.
Eliminated several log code dependencies from other
parts of Ziproxy.
Obsoleted AccessLogUserPOV option, due to code
maintainability concerns and small importance of
that option.
cttables.c:
Crashes occured when trying to compare a NULL (absent)
content-type. Fixed.
http.c:
Ziproxy returned garbage to the user when receiving
an empty response (0 bytes, no headers), instead of
issuing an error message. Fixed.
configure.in image.c:
Fixed compilation errors while compiling with libpng 1.4.
Should still compile with not-so-old previous libpng
versions.
cfgfile.* netd.c:
Added support for simultaneous user connection limit.
New option: MaxActiveUserConnections

if this feature is not used.
New option: PIDFile
cfgfile.* netd.c:
Obsoleted NetdTimeout and removed related code.
cfgfile.* gzpipe.c http.c ziproxy.c:
Renamed parameter "ZiproxyTimeout" to "ConnTimeout".
Deprecated option: ZiproxyTimeout (still functional)
New option: ConnTimeout
cfgfile.* netd.c:
Added security options to run daemon as different user/group.
New options: RunAsUser, RunAsGroup
cfgfile.c image.c ziproxy.c:
Fixed old error output messages which used stderr directly,
instead of the proper log subsystem.
This fixes situations where broken GIFs resulted in
corrupted HTTP response.
cfgfile.* netd.c:
Added CLI parameters to set user/group.
cfgfile.* netd.c:
Added CLI parameter to set PID file.
netd.c:
Improvements on the daemon fail routines.
Now avoids unnecessary daemon abortions and busy loops.
netd.c:
Killing the daemon stops all children processes too.
Added verbosity to certain daemon errors.
ziproxy.c log.*:
Added support for SIGTERM interception.
Now transfers interrupted such way as logged aswell.
Added 'X' flag support to AccessLog.
netd.c log.*:
Added 'daemon' subsystem to error_log.
Updated daemon-related messages to report accordingly.
netd.c:
Added code to remove PID file in case of daemon
startup failure at a later stage.
3.1.2010 Daniel Mealha Cabrita
version 2.7.9_BETA2
image.c:
Under certain circumstances, certain PNG pictures
could not be decompressed. Fixed.
This bug affected certain architectures, such as x86-64.
cfgfile.c qparser.*:
Added support for errors informing about obsoleted
configuration parameters, instead of just erring
as if it was a mere syntax error.
Obsolete parameters from previous versions were added.
cfgfile.c qparser.*:
Added support for errors informing about unsupported
configuration parameters (eg. features disabled
during compilation), instead of just erring
as if it was a mere syntax error.
Added JP2K-related parameters to this list.

Obsoleted LogPipe option and removed all related code.
cfgfile.c log.* netd.c text.c tosmarking.h ziproxy.c:
Minor miscellaneous fixes. Eliminates some compiler warnings.

Massive log-related functions renaming (in the source code)
to avoid confusion between different types of logging and
to improve code readability in general.
New option: DebugLog
JPEG2000.ru.txt README.ru README.tools.ru
ziproxylogtool.ru.1 ziproxy.ru.1:
Removed all Russian translations, due to lack of maintainer.
change_tos.list:
Added example file for TOSMarkAsDiffURL option.
cfgfile.* http.c:
Changed content-type gzip compression matching code.
Now it's possible to specify any content-type instead of
only subtypes of "application/".
Deprecated option: Compressible (still functional)
New option: LosslessCompressCT
cfgfile.* log.c:
Renamed parameter "AccessLogFileName" to "AccessLog".
Deprecated option: AccessLogFileName (still functional)
New option: AccessLog
cttables.c misc.*:
cttables was case-sensitive, that's against
RFC 1049 (RFC 1341). Fixed.
cfgfile.* http.c:
Added switch for "x-" subtype prefix matching for
content-type lists.
Migrated URLReplaceDataCTList to new content-type
lists subsystem.
New options: TOSMarkAsDiffCTAlsoXST,
URLReplaceDataCTListAlsoXST,
LosslessCompressCTAlsoXST
gzpipe.* http.* image.* log.* simplelist.c text.*
tosmarking.* globaldefs.h:
Changed filesize counter from signed int (usually 32 bits,
even in 64-bit architectures) to a local type (defined
during compile time, being that at least 64 bits).
The most perpectible effect is seen in logs (no longer
wrong, often negative, size numbers for anything > 2GB).
This also fixes the data size limitation (up to 2GB) in
cases where Content-Lenght was used such as
HTTP method CONNECT, URLNoProcessing.
gzpipe.c log.* ziproxy.c ziproxy.conf:
Added 'G' flag support to AccessLog.
Added verbosity to streaming gzip/gunzip errors in DebugLog.
cfgfile.c ziproxy.conf:
Changed default of MinUncompressedGzipStreamEval from
250000 (~250kB) to 10000000 (~10MB).
This avoids trigging of MaxUncompressedGzipRatio if
ISO9660 images are compressed while streaming (the
first MBs of ISOs are highly compressible).
cfgfile.c ziproxy.conf:
Added "application/iso9660-image" content-type as
compressible (losslessly), in default settings.
log.c globaldefs.h:
Changed time measurement from signed int (usually 32 bits,
even in 64-bit architectures) to a local type (defined
during compile time, being that at least 64 bits).
Fixes problems of time logging of long downloads (>2G
microseconds, or >35 minutes) which previously gave
wrong, often negative, times.
cfgfile.* image.c log.* netd.c ziproxy.conf:
Implemented an internal error-message handling system.
Added more verbosity to error/warning conditions.
Previously unreported errors now appear.
Minor fixes in cfgfile.*.
Some code reorganization in log.*.
New option: ErrorLog
Obsoleted option: MSIETest
README src/*:
Updated copyright year to current one.
14.12.2009 Daniel Mealha Cabrita

Removed. Unable to maintain this file properly.
29.9.2009 Daniel Mealha Cabrita
version 2.7.2
README* image.* ziproxy.* netd.* ziproxy_genhtml_stats.sh:
Fixed Juraj's copyright years, considering old
code from 2002.
log.* ziproxy.c:
LogFile timer was not properly initialized and
the first measurement was always wrong. Fixed.
12.9.2009 Daniel Mealha Cabrita
version 2.7.1
http.c:
Fixed HTTP/0.9 simple response support,
which was broken for aeons and nobody noticed.
text.c:
Gunzipped data smaller than the compressed was
being treated as corruped and data was simply
forwarded as is.
But that's not necessarily true (a certain website
thought it was a good idea to gzip jpegs, for example)
and in certain cases processing was not
applied because of that. Fixed.
http.c:
Implemented workaround for buggy sites which send:
Content-Encoding: ISO-8859-1 (violates RFC 2616).
Fixes certain pages which appeared as binary garbage
in the browser.
13.4.2009 Daniel Mealha Cabrita
version 2.7.0
README.ru:
Added note stating this documentation is
currently outdated.
13.3.2009 Daniel Mealha Cabrita

rare, specific situations while compressing to
jp2k.
cfgfile.* log.c ziproxy.c:
Added provision for crash (signal) interception
and logging (see new access log flags).
New option: InterceptCrashes
image.*:
Renamed image retcodes to a more standard
and uniform naming, for better code readability.
image.* cfgfile.* http.c log.* ziproxy.c:
Added feature against "image bomb" DoS.
New option: MaxUncompressedImageRatio
image.c:
Fixed bug in rgb2yuv converter. In certain cases jp2
pictures had some very wrong colors (like deep red turned
into strong pink etc).
cfgfile.* http.* image.c text.* txtfiletools.c ziproxy.c:
Obsoleted ModifySuffixes. It was buggy and lost its
usefulness a long ago.
The following config options are obsolete:
ModifySuffixes, MinTextStream
The following files were removed:
cfgtest.c
htmlmodify.h
htmlmodify_jp2.l
htmlmodify.l
imgtest.c
Makefile
modifytest.c
Also, additional code cleanup was done.
Test programs were obsolete and were
removed (imgtest, modifytest, cfgtest)
and no longer are a build option.
Flex is no longer required for building Ziproxy.
cfgfile.c:
Preventive bugfix (did not cause problems yet).
cfgfile.* http.c:
Added support for content substitution
by matching URL + content-type.
New options: URLReplaceDataCT, URLReplaceDataCTList
cfgfile.* http.c:
Added support for URL blocking.
New option: URLDeny

version 2.6.9_BETA
cfgfile.* http.c:
Added support for custom 403 error pages.
http.* ziproxy.c:
Fixed the type/signedness mess with outgoing Port vars.
Ports >= 32768 were not accessible.
Non-standard HTTP/HTTPS ports (non-80/443) were not
accessible in big-endian architectures.
cfgfile.* http.* ziproxy.c:
Added provision for outgoing port restrictions.
New options: RestrictOutPortHTTP, RestrictOutPortCONNECT
cfgfile.c ziproxy.conf:
Changed JPG and JP2K default settings to (hopefully)
better values.
image.c:
Bug which prevented recompression to jp2k
when more aggressive parameters were set to
color components, original image was forwarded
instead. Fixed.
jp2tools.* cfgfile.*:
Added Lanczos component upsampler support to JP2k.
New option: JP2Upsampler
image.c:
Encoding/decoding jp2 images with alpha channel
always fails. Fixed.
ziproxy_genhtml_stats.sh:
Fixed help message.
26.11.2008 Daniel Mealha Cabrita
version 2.6.0
ziproxy.ru.1 ziproxylogtool.ru.1:
Added Russian manpages.

Added Russian version of text documentation.
http.c ziproxy.conf cfgfile.*:
Added support for custom 407 and 409 error
pages.
http.c:
Under random conditions or unrelated configuration
changes the pictures were not recompressed.
Fixed.
http.c embbin.h:
Changed from 1x1 PNG to 1x1 GIF due to smaller
size of the latter.
2.9.2008 Daniel Mealha Cabrita
version 2.5.9_BETA
http.c cfgfile.* replace.list embbin.h:
Added support for data replacement using
a URL list.
New option: URLReplaceData
http.c auth.* log.*:
Now a authenticated connection also logs the
username alongside its IP (username@X.X.X.X).
ziproxy.c simplelist.* cfgfile.* bo_exception.list:
Added support for host exception list when
using the BindOutgoing option.
New options: BindOutgoingExList, BindOutgoingExAddr
31.3.2008 Daniel Mealha Cabrita
version 2.5.2
http.c:
Proxy authentication would bring access denial
if such was not requested by Ziproxy (that means
unnecessary authentication).
Now it is simply ignored and access is normal.
http.c:
Ziproxy did not send the proper URL to the
server (so it failed) when connecting to another proxy
_and_ the client accessed Ziproxy in transparent
proxy mode. Fixed.
10.3.2008 Daniel Mealha Cabrita
version 2.5.1
http.c:
Originally gzipped data, one not processable,
to a client which supports gzip was being loaded
wholly into memory then recompressed back.
Now it's streamed directly to the client.
(thus less latency)
28.1.2008 Daniel Mealha Cabrita
version 2.5.0
image.c:
JP2 component bitdepth set as !=8 would make
the process crash. Fixed.
cfgfile.c:
Certain defaults were unoptimal. Fixed.
ziproxy.conf:
Reorganized example configuration file,
clearer to read now.
16.1.2008 Daniel Mealha Cabrita
version 2.4.8_BETA2
man/*:
Added manpages for ziproxy and ziproxylogtools.
http.* ziproxy.c txtfiletools.* urltables.* qparser.c:
Added support for list of URLs that should not be
processed by Ziproxy (due to bugs/incompatibilities).
New option: URLNoProcessing
ziproxy.conf:
ATTENTION: Changed the default location of
ziproxy.conf to /etc/ziproxy/ziproxy.conf
(was /etc/ziproxy.conf)
noprocess.list:
Added example configuration file.
auth.* strtables.* urltables.* http.c:
Routines for (basic) authentication mostly
rewritten.
Perceptible site-effect: comments are now
allowed in http.passwd file.
7.1.2008 Daniel Mealha Cabrita
version 2.4.8_BETA
image.c http.c cfgfile.*:
Added input processing for JPEG 2000 files.
Previously Ziproxy could only compress to that
format. Now it is able to recompress and
even convert to other formats.
Now it is possible to compile with JP2K support
and disable that through the config file.
New options: ProcessJP2K, ForceOutputNoJP2K, ProcessToJP2K
image.c:
Major optimizations to the existing JP2K code
(the compression-to-JP2K code).
http.c:
Streaming data (no Content-Length) could be prematurely
interrupted in certain cases. Fixed.
image.* http.c cfgfile.*:
Added support for YUV color model for JP2K files.
New option: JP2Colorspace
image.* http.c cfgfile.*:
Added support for component and individual component
resolution (bit-wise) for JP2K files.
New options: JP2BitResYA, JP2BitResRGBA, JP2BitResYUVA
image.* cfgfile.*:
Now JP2K compression is specified in a similar way
as JPG files (quality-wise, instead of rate).
New option: JP2ImageQuality
Obsoleted option: JP2Rate
image.* cfgfile.* jp2tools.*:
Added suport for component sampling.
New options: JP2CSamplingYA, JP2CSamplingRGBA, JP2CSamplingYUVA
image.* cfgfile.* http.c:
Added switches for selective JP2 output support.
New options: AnnounceJP2Capability, JP2OutRequiresExpCap
JPEG2000.txt:
Rewritten from scratch.
15.12.2007 Daniel Mealha Cabrita
version 2.4.3
Special version with urgent bugfix backport.
This version is not present in CVS repository as is.
http.c:
Streaming data (no Content-Length) could be prematurely
interrupted in certain cases. Fixed.
4.12.2007 Daniel Mealha Cabrita
version 2.4.2
http.c:
Fixed broken user pipe detection while transferring
unprocessed stream-to-stream.
ziproxy.c log.*:
When server breaks the connection, ziproxy immediately
interrupted the transfer at client's side.
Now it will send the remaining data to the client.
The previous behavior could bring premature
disconnections.
text.c:
Content-Length wasn't being removed while
stream-to-stream gunzipping. Fixed.
ziproxy.c log.c:
Ziproxy crashed when AccessLogFileName wasn't defined.
Fixed. This bug appeared in 2.4.1 version.
ziproxy.c log.*:
Now (debug) log provides each line with the PID of the
specific process servicing the specific HTTP request.
Previously it merely provided the base Ziproxy process,
what is pretty much useless in daemon mode and made
sense only while using (x)inetd, or in pre-1.9.0 versions.
http.c:
Stream-to-stream (no further processing) routines were
rewritten and are >100x times faster now. This may bring
noticeable difference in cases where outgoing data
is something like 10 Mbps or more.
Added access log flag 'W'.
22.11.2007 Daniel Mealha Cabrita
version 2.4.1
cfgfile.* netd.c ziproxy.*:
New option: BindOutgoing
cfgfile.* http.c:
New option: AccessLogUserPOV
ziproxy.conf:
Added new xml types as (gzip) compressible.
Added 'pdf' and 'tar' as compressible application types.
gzpipe.c ziproxy.c http.* log.*:
Added access log support for interrupted/timeouted transfers.
Added access log flags 'Z' (timeout)
and 'B' (broken pipe, interrupted)
image.c:
When decompressing jpeg incomplete files, ziproxy process
crashes (busy loops) until it timeouts. Fixed.
28.10.2007 Daniel Mealha Cabrita
version 2.4.0
http.*:
If data is > MaxSize, junk was appended to the beginning
of it. Fixed.
Ziproxy tried to load into memory, data types which are
not supposed to be processed. Fixed.
text.c:
Trivial overflow problem which gave false positives
for "gunzip threshold limit". Fixed.
qparser.c:
When config file was essentially empty (only comments
or spaces) ziproxy issues this error:
ERROR: Invalid parameter --> <empty>
Fixed.
gzpipe.c:
Fixed intermitent bug when gzip-streaming pages
(random numbers appeared in the body of the page, mixed
with the content). This bug appeared in 2.3.5_BETA.
cfgfile.* http.c gzpipe.*:
New option: MinUncompressedGzipStreamEval
htmlopt.* http.c fstring.* cdetect.*:
Added support for javascript files as text/javascript.
Now tests whether text/html is indeed html
(not always the case, may be JS, CSS...)
Misc fixes to html opt (support more sites now).
25.10.2007 Daniel Mealha Cabrita
version 2.3.5_BETA
http.c:
Broken gzip were not being uncompressed (that's ok)
but Ziproxy attempted to recompress those again. Fixed.
http.c:
Requests were broken when in transparent proxy mode _and_
the client explicited the port. Fixed.
various_files:
Fixed missing includes and certain inconsistencies in the
source code.
Removed unused variables.
Fixed (hopefully) all pointer compares in order to use NULL
instead of 0.
Those potentially preventing compilation in
certain systems.
qparser.*:
Replaced libconfuse with qparser, thus that library is
no longer used.
Fixes x86_64 (and possibly other arches) parsing problems.
configure.in:
Now check all headers used in source code.
http.* cfgfile.*:
New option: WA_MSIE_FriendlyErrMsgs
Misc bug fixes and code cleanup.
MinTextStream was using the decompressed size, what is
senseless if the data came pre-compressed by the remote
server. Fixed.
http.*:
Added (limited) support for partial data download
(Content-Range, Range).
"multipart/byteranges" mode works aswell (as side effect),
and that's a BUG. This must be disabled later
since it can build corrupt data at the user's end
(when dealing with jpg/gif/png and htmlopt-processed files).
http.* text.* gzpipe.*:
Added gzip/gunzip stream-to-stream support. Appliable
when no other optimizations are requested/viable.
Now logs aloways report gzipped transfers new sizes
(previously, streaming cases were reported as "-1").
A number of bugs fixed related to incoming gzipped data.
cfgfile.c ziproxy.conf:
Misc updates/improvements to the example config file.
Changed some defaults to more sensible values.
11.9.2007 Daniel Mealha Cabrita
version 2.3.0
ziproxy.c:
Alternative network code for IPv4-only OSes was
completely broken. Fixed.
htmlopt.c:
Broken commented CDATA in JS processing.
Some pages using htmlopt were rendered broken.
Fixed.
http.c, cfgfile.*:
New option: AllowMethodCONNECT
http.c:
(default) error messages now contain some
meaningful info at the footer of the page,
like date and hostname.
http.* text.* cfgfile.*:
Ziproxy now supports internal processing of
gzipped data.
Now also possible to always advertise gzip capability,
no longer being dependant on the http client.
New option: OverrideAcceptEncoding
New option: MaxUncompressedGzipRatio
http.c cfgfile.*:
New option: RedefineUserAgent
http.c cfgfile.*:
New option: DecompressIncomingGzipData
Many fixes/changes in the HTTP processing routines.
htmlopt.c:
Changed quirky-linebreak processing to be more
like mainstream browsers, for more correct
rendering of certain broken pages.
htmlopt.* cfgfile.* http.c:
Fixed bug in HTMLopt which caused losing formatation
in textarea.
New option: ProcessHTML_TEXTAREA
htmlopt.c:
Fixed bugs related to javascript processing.
8.5.2007 Daniel Mealha Cabrita
version 2.2.2
http.h:
Some files with too many headers were not loadable
(typically some wikipedia.org pictures). Fixed.
htmlopt.c:
Fixed commented (escaped, in a way) CDATA XML tag
which was being removed.
http.c:
Fixed trailing trash in html/javascript/css
when code optimization is enabled.
ziproxylogtool.c:
Added internal caching
(about 4.5x faster in large logs now)
Makefile.am:
README.tools was left behind. Added into.
18.12.2006 Daniel Mealha Cabrita
version 2.2.1
cfgfile.c:
Fixed compilation issues with FreeBSD
(possibly affecting other OSes aswell)
ChangeLog:
Removed duplicated entry from 17.12.2006
CREDITS:
Some people were left out, fixed.
17.12.2006 Daniel Mealha Cabrita
version 2.2.0
cfgfile.*, ziproxy.c:
New option: ConventionalProxy
http.c:
Fixed: standalone javascript files were not being
compressed, even when GZip=true
cfgfile.c:
Fixed: AllowLookChange default was not false
as it should be.
cfgfile.*, netd.c:
New option: Address
cfgfile.c:
New option: Nameservers
netd.c:
Ziproxy collected zombie childs only when a new incoming
connection arrived, what is not very elegant when
Ziproxy is in idle state and one type something like
$ ps xa | grep ziproxy
Fixed.
http.c:
Fixed: Ziproxy handled incorrectly 30x HTTP responses.
Certain sites were inaccessible.
tools/*:
Added Ziproxy Log Tools.
2.9.2006 Daniel Mealha Cabrita
version 2.1.1
text.c:
Fixed a compilation bug when Jasper (JP2K) is enabled.
(This bug was introduced in version 2.1.0)
cfgfile.c:
Changed the default behavior of ModifySuffixes (when Ziproxy
is compiled with Jasper) to FALSE, in order to avoid more
problems. (Modify Suffixes is _very_ broken).
26.7.2006 Daniel Mealha Cabrita
version 2.1.0
htmlopt.*:
EXPERIMENTAL FEATURE:
Inserted htmlopt into the code, a html/css/js
optimizer meant to reduce file size even further
prior to gzip compression.
cfgfile.*:
Added options: ProcessHTML, ProcessCSS, ProcessJS
and ProcessHTML_*
http.c:
Fixed a bug which made PreemptNameRes to scan
images too, wasting cpu time.
Also fixed a bug which could potentially lock
the ziproxy process while trying to compress
non-pictures as pictures.
29.6.2006 Daniel Mealha Cabrita
version 2.0.0 (final)
