Revision history for CGI-Buffer
0.80 Mon Sep 25 13:03:24 EDT 2017
Remove false positive bug reports
Work with the latest IO::Compress::Brotli
0.79 Fri Jan 6 11:17:01 EST 2017
Fix Brotli tests which failed in some places
Improved handling of HTTP status
Put different languages in different caches
0.78 Mon Oct 10 09:35:18 EDT 2016
Print stack trace when calling init too late
Support Brotli
Honour the order of HTTP_ACCEPT_ENCODING

Call the right routine
0.76 Sun Feb 14 19:10:51 EST 2016
generate_key - honour the vary header
Fix problem were server side cached contents weren't compressed when
loading the content from the cache
If you give a cache to init() then later give cache => undef,
the server side cache is no longer used.
0.75 Sun May 17 09:00:46 EDT 2015
Added X-Cache and X-Cache-Lookup headers
Fixed overly agressive optimisation
Don't use the cache if the client sends max-age=0
Added cache_age option to init()
Fix set_options when given a ref
Fix RT102226
Improved handling of Wide characters
0.74 Sat Jan 24 10:47:50 EST 2015
Added t/strict.t, t_unused.t and t/used.t
When a script has been updated clear all the cache
Added can_cache()
0.73 Fri Nov 7 16:48:40 EST 2014
It's is_search_engine, not is_search!
Fix missing encoding_utf8
0.72 Fri Nov 7 11:03:55 EST 2014
Added the info option to init
Removed some unused modules, and defer loading others
Removed Exporter and use vars, use our instead
Separate the web and mobile caches
0.71 Wed Apr 2 16:50:48 EDT 2014
Speed optimisation with some output
0.70 Fri 13 Dec 10:24:45 EST 2013
Loop optimisation until complete for even smaller output
Use Test::Tempdir to create the temporary files when testing
# Use RegExp::List to consolidate some scans of the output
Ensure logger isn't called after it's been destroyed since that
would cause Log4Perl to say it hasn't been initialised
Use $cobject->value() rather than $cache->get() to see if the
object data is there as well. There were some false
negatives
Accept HTTP_TE as well as HTTP_ACCEPT_ENCODING
Output parsing improvements courtesy of Regexp::List
Use Test::Most instead of Test::More
Support HTTP_RANGE as well as Range
Added more JavaScript optimisations when optimise_level >= 2
0.69 Tue Apr 2 14:59:59 EDT 2013
Bumped minimum version of CGI::Info, needed for Cygwin
t/output.t: try harder to ensure the "to be tested" version of
CGI::Buffer is tested
Minor speed improvements
_check_modified_since, fix in 0.68 was broken
0.68 Sat Feb 2 12:13:03 EST 2013
Handle situation where not modified but Etag is different would
generate 304
Added generate_304 option (defaults to 1)
Handle situation where IF_MODIFIED_SINCE isn't a valid date
On some platforms (e.g. Cygwin) t/is_cached is failing, so
added debugging to find out why
0.67 Sun Oct 21 23:00:13 EDT 2012
Remove spaces after <body>.
Fix removal of spaces between </head> and <body>.
Better handling of no body, e.g. when redirecting using Location
0.66 Thu Oct 11 12:11:11 EDT 2012
Add sanity check.

General tidy up and minor speed improvements
Improved handling of cache errors
0.64 Mon Sep 24 17:08:15 EDT 2012
Only store in the cache when status is 200
0.63 Sat Sep 22 18:45:27 EDT 2012
Fixed t/is_cached.t for systems without CHI
Sometimes 304 was not generated for when giving IF_MODIFIED_SINCE in
scenarios were it could have been
Amalgameted that 3 separate caches into one cache.
Minor speed improvements
0.62 Wed Sep 19 10:09:53 BST 2012
Added resilience to is_cached in case the age of the script can't be
determined.
Removed logger calls from END, since it'll have gone by then
is_cached now returns false unless both body and headers can be found
0.61 Sat Sep 15 17:57:03 BST 2012
Fixed typo in subroutine name
0.60 Fri Sep 14 08:44:00 BST 2012
Removed superflouous whitespace around the top of the document and
in lists
Added t/unused.t
Remove spaces after <div>
Remove spaces before </div>
Simplified the cache key
If the script has been modified since the value in IF_MODIFIED_SINCE
don't return 304, since the output may have been changed
If the script has been modified since the time it was stored in the cache
don't return true from is_cached()
Use the cookies to ensure that different states of the client are stored
in different entries in the cache
0.59 Wed Aug 8 10:00:00 BST 2012
t/is_cached: fix tests on systems without CHI
0.58 Tue Aug 7 12:40:03 BST 2012
Improve the new-line handling between header fields
Replaces stats_file option with logger
Fix putting Content-Length in twice when cache is given
Optimise <hr> tags

Test::Kwalitee isn't needed for build, only for optional testing
Only get the etag value from the cache when needed
0.57 Tue Jul 24 13:51:43 BST 2012
Use get() rather than is_valid()
If get on the body fails, remove the corresponding headers from the
cache
0.56 Tue Jul 24 13:45:57 BST 2012
Always store the unzipped body in the cache. It uses more disc
space, but makes the code much simpler and more robust
0.55 Mon Jul 23 12:14:34 BST 2012
Only store a response in the cache when HTTP status is 200
Ensure that the headers are in the cache as well as the body
before deciding to send the server's cached response

Store the etag value in the cache to ensure correctness

Fixed use of an uninitialised variable
Don't set 304 if status != 200
0.49 Sun Jun 17 22:57:52 EDT 2012
Made the stats_file more readable
Fixed IF_MODIFIED_SINCE which was often not working
0.48 Sun Jun 17 08:48:25 EDT 2012
Added stats_file option
0.47 Fri Jun 15 12:56:57 EDT 2012
Fix bug where 307 wasn't sent if the first request set encoding to gzip
and subsequent check didn't
0.46 Sat Jun 2 14:02:39 EDT 2012
304 can be sent irrespective of the value of gzip - so check
for both in the cache
0.45 Tue May 29 12:19:41 EDT 2012
Honour Cache-Control: private
Look at If-Modified-Since before If-None-Match to reduce etag
calculations
Unlikely possibility: if cached headers have an etag that matches our
body but we somehow missed that, then send 304
0.44 Mon May 28 10:39:57 EDT 2012
Corrected logic error
0.43 Mon May 28 00:31:40 EDT 2012

Renamed set_options to init, but kept set_options as a synonym for
legacy apps
Allow a reference to be passed to init
0.39 Fri Apr 20 09:04:51 BST 2012
Avoid "Wide character in subroutine entry" when generating ETags
Remove warning on perl5.15.9
Added tests that If-None-Match can generate 304 return status
0.38 Wed Apr 18 11:32:31 BST 2012
Only do kwalitee test in author environment because it throws too
many false positives
Remove blank spaces between table cells
0.37

Fix occasional unitialised value
Various performance enhancements
Use Digest::MD5 instead of MD5
0.32 Sat Feb 25 16:53:39 EST 2012

Handle Range header
Fixed t/output.t to look in PERL5LIB for locally installed modules
0.30 Sat Feb 18 12:37:29 EST 2012
Don't gzip if the output is < MIN_GZIP_LEN
Honour cache-control HTTP header
0.29
Added tests to t/output.t to verify that Content-Length is correct
Don't tell HTML::Packer to remove newlines.
0.28 Sun Jan 29 12:33:55 GMT 2012
Fixed test count in t/output.t
0.27 Sat Jan 28 11:04:32 GMT 2012
Use the domain name as part of the key, so that if two scripts of
the same name are used in different hosts, ensure that they
are kept separate
Remove use of JavaScript::Packer. It produces JavaScript that doesn't
work - I don't know what's wrong.
Fix bug removing our own name in links to our own domain
0.26 Fri Jan 27 11:07:13 GMT 2012
Added t/output.t
Use shrink not best in JavaScript::Packer

Fixed the way HTML::Packer was called
0.24 Tue Jan 24 21:59:00 GMT 2012
Include HTML::Packer. Eventually I will probably drop HTML::Clean,
so I'm testing HTML::Packer. HTML::Clean doesn't seem to
be supported any more
0.23
Improved header handling when caching few headers
0.22 Fri Jan 6 20:58:43 EST 2012
Ensure that two newlines are appended when doing redirects
