<br><p><a name="3124">v0.50_20061222_3124</a>
|
|
<ul>
|
|
<li>Added Media Search</li>
|
|
<ul>
|
|
<li>Added search pages for Images, Audio, Video and Application search.</li>
|
|
<li>Added media link presentation during snippet fetch; the Image Search presents search results as image thumbnails.</li>
|
|
<li>Better recognition of search hits for text snippet generation.</li>
|
|
<li>Media search results are indexed again after remote search results are collected; only media links are used to update the index.</li>
|
|
</ul>
|
|
<li>Better Result Ranking</li>
|
|
<ul>
|
|
<li>New ranking parameters and appearance attributes are now considered.</li>
|
|
<li>Faster ranking; more references can be ranked and sorted within given search time.</li>
|
|
<li>Ranking Parameters can be handed over to remote peers and are applied there.</li>
|
|
<li>Adopted Detailed Search to new ranking parameters.</li>
|
|
<li>Coefficients from detailed search can be set as default ranking for search page; this replaces the old ranking alternatives.</li>
|
|
</ul>
|
|
<li>Better Crawl Monitoring</li>
|
|
<ul>
|
|
<li>After a crawl start was initialized, the Crawler Monitor is shown.</li>
|
|
<li>The Crawl Monitor now shows all queue elements in one table.</li>
|
|
<li>Monitoring of index size.</li>
|
|
<li>The Crawl Profiles are shown; crawls can be interrupted within the profile table.</li>
|
|
<li>A crawl may now distinguish between text indexing and media link indexing.</li>
|
|
</ul>
|
|
<li>Migration to new Database Structure</li>
|
|
<ul>
|
|
<li>The new Collection Database is now the only database structure that can be used; Assortments are switched off.</li>
|
|
<li>Added functions to migrate Assortment databases and WORDS databases to Collection database.</li>
|
|
<li>Removed all methods to write Assortment data structures.</li>
|
|
<li>Migrated DHT position computation to base64-decoded values; this changes the DHT structure slightly and closes the gaps in the old DHT structure.</li>
|
|
</ul>
|
|
</ul>
|
|
|
|
<br><p><a name="3040">v0.49_20061202_3040</a>
|
|
<ul>
|
|
<li>Enhanced search service</li>
|
|
<ul>
|
|
<li>Web searches are faster because of the new data structures implemented in this version (see below)
|
|
and because bugs had been found and fixed.</li>
|
|
<li>Searches can be re-done with changed search properties. Please use the 'more options' link at the search page.</li>
|
|
<li>Added search constraints. These are search restrictions to web searches which are applied to information that is scraped
|
|
from the web pages during page parsing. The first application of search constraints is a search restricted to
|
|
index pages ('index of'). Please use the flag at the extended search functions.</li>
|
|
<li>Enabled index-abstracts search; this should solve the distributed-combined search challenge (still beeing tested).</li>
|
|
</ul>
|
|
<li>New Database Structures for Index and URL storage</li>
|
|
<ul>
|
|
<li>The new 'Collections' Data Structure is now the default data structure.</li>
|
|
<li>Index entries and URL entries carry more ranking and selection attributes, e.g. for image, video, audio and application search.</li>
|
|
<li>Enhanced Storage of URLs: they are now divided into different creation times. This enables easy deletion
|
|
of outdated URLs, enables a index-limitation function and solves the problem that the URL database was too
|
|
big to fit into a 2 GB file.</li>
|
|
<li>Search requests can now be answered in less time.</li>
|
|
<li>The index organization needs less IO.</li>
|
|
<li>Index transfers will now only be done to latest peers supporting the collection data structure.</li>
|
|
<li>Index transfers from old peers to new peers are translated automatically to new data format.</li>
|
|
<li>Assortments are no longer supported.</li>
|
|
</ul>
|
|
<li>Enhanced SOAP support</li>
|
|
<ul>
|
|
<li>Added protocol for peer administration, custom services, status queries, blacklist management,
|
|
file share management, support for outgoing transfer- and content-encoding, better error handling,
|
|
function to get and set message forwarding, handling of YaCy bookmarks, log display,
|
|
manage peer messages, get and set peer profile, query peer status, query the pause/resume state of the crawling queues,
|
|
and a check if a specific URL is blacklisted.</li>
|
|
<li>Added new ANT target to allow generation of client stub classes for YaCy SOAP api.</li>
|
|
</ul>
|
|
<li>Other new Features</li>

|
|
<li>More anonymization in logging.</li>
|
|
<li>New HTCACHE layout using files hashes; tree- and hash-layout can be used simultanously; hash-layout is now default.</li>
|
|
<li>Access to wiki is now limited to administrator, if wanted. This can be configured at the wiki page.</li>
|
|
<li>..and many bugfixes.</>

|
<ul>
|
|
<li>Index distribution to DHT now fully active</li>
|
|
<ul>
|
|
<li>All peers, principal, senior and junior peers distribute their index to other principal or senior peers. Juniors send their index to only one principal/senior peer, while principal/senior peers distribute to 3 redundant other peers.</li>
|
|
<li>The index distribution and the index receive flag on Index-Control must be set to enable global search on the own peer</li>
|
|
<li>For a global search, only relevant peers according to DHT rules are selected</li>
|
|
</ul>
|
|
<li>New YaCyNews feature</li>
|
|
<ul>
|
|
<li>A new menu 'News' shows the news processing queues for incoming and outgoing news. However, news shall not be monitored here but they influence the presentation of other information throughout the system:</li>
|
|
<li>The Index-Create menu now shows a list of previously started crawls of other peers. They are distinguished between Crawls in progress and finished crawls.</li>
|
|
<li>When a Crawl in the Index-Create menu is started with the 'RemoteIndexing' - flag set on, then automatically a YaCyNews is generated to inform other peers about that crawl start. A message can be attached to explain why this crawl was startet.</li>
|
|
<li>When a personal profile is changed, a News Message is generated.</li>
|
|
<li>When a Wiki entry is changed, a Message is generated.</li>
|
|
<li>Within the Network menu, Alerts for Profile Updates, Wiki Updates and Cralws in Progress may appear.</li>
|
|
</ul>
|
|
<li>The YaCy wiki has enhanced and was moved out from the 'Lab' to the main menu. The Wiki-System now supports embedded images and can show a preview.</li>
|
|
<li>New logging policy: logs are now exclusively written to the rotating logs in <app-home>/log/</li>
|
|
<li>Search was enhanced using the intermission feature (all other processes are paused while search is in progress)</li>
|
|
<li>Enhancements to Translation/Localization</li>
|
|
<li>Proxy-Caution-Delay (forced idle time of the crawler after a proxy access) is now configurable in the Performance menue</li>
|
|
<li>Many bugfixes for time-out problems, database crashes, DHT management, version numbers</li>

|
|
<br><p><a name="424">v0.39_20050722_424</a>
|
|
<ul>
|
|
<li>New Features:</li>
|
|
<ul>
|
|
<li>Added snippets to search results. Snippets are fetched by searching peer from original web sites and are also transported during result transmission from remote search results.</li>
|
|
<li>Proxy shows now an error page in case of errors.</li>
|
|
<li>Preparation for localization: started (not finished) German translation</li>
|
|
<li>Status page shows now memory amount, transfer volume and indexing speed as PPM (pages per minute). A global PPM (sum over all peers) is also computed.</li>
|
|
<li>Re-Structuring of Index-Creation Menue: added more submenues and queue monitors</li>
|
|
<li>Added feature to start crawling on bookmark files</li>
|
|
<li>Added blocking of blacklistet URLs in indexReceive (remote DHT index transmissions)</li>
|
|
<li>Added port forwarding for remote peer connections (the peer may now be connected to an configurable address)</li>
|
|
<li>Added bbCode for Profiles</li>
|
|
<li>Memory Management in Performance Menu: a memory-limit can be set as condition for queue execution.</li>
|
|
<li>Added option to do performance-limited remote crawls (use this instead to switch off remote indexing if you are scared about too much performance loss on your machine)</li>
|
|
<li>Enhanced logging, configuration with yacy.logging</li>
|
|
</ul>
|
|
<li>Performance: enhanced indexing speed</li>
|
|
<ul>
|
|
<li>Implemented indexing/loading multithreading</li>
|
|
<li>Enhanced caching in database (less memory occupation)</li>
|
|
<li>Replaced RAM-queue after indexing by a file-based queue (makes long queues possible)</li>
|
|
<li>Changed assortment cache-flush procedure: words may now appear in any assortment, not only one assortment. This prevents assortment-flushes, increases the capacity and prevents creation of files in DATA/PLASMADB/WORDS, which further speeds up indexing.</li>
|
|
<li>Speed-up of start-up and shut-down by replacement of stack by array. The dumped index takes also less memory on disk now. Because dumping is faster, the cache may be bigger which also increases indexing speed.</li>
|
|
</ul>
|
|
<li>Bugfixes:</li>
|
|
<ul>
|
|
<li>Better shut-down behavior, time-out on sockets, less exceptions</li>
|
|
<li>Fixed gzip decoding and content-length in http-client</li>
|
|
<li>Better httpd header validation</li>
|
|
<li>Fixed possible memory leaks</li>
|
|
<li>Fixed 100% CPU bug (caused by repeated GC when memory was low)</li>
|
|
<li>Fixed UTF8-decoding for parser</li>
|
|

|
<br><p><a name="208">v0.38_20050603_208</a>
|
|
<ul>
|
|
<li>Enhanced Crawling:
|
|
<ul>
|
|
<li>There are now 3 different crawl threads: local crawling, global crawl trigger and remote-triggered crawl jobs.</li>
|
|
<li>The thread pools can now be configured through the Performance-Menu and a customized number of crawling threads is possible.</li>
|
|
<li>Crawling can be paused and resumed.</li>
|
|
<li>Changed method of index caching; this speeds up crawling and provides a more economic data structure.</li>
|
|
</ul>
|
|
</li>
|
|
<li>Enhanced Proxy: added transparent proxy support. It is now possible to route http traffic through yacy without setting a proxy configuration in browsers. Example: set your iptables configuration with <br><tt>iptables -t nat -A PREROUTING -p tcp -s 192.168.0.0/16 --dport 80 -j DNAT --to 192.168.0.1:8080</tt></li>
|
|
<li>Extended seed-upload methods for principal peers: more configuration options, better extensibility. Added support for scp.</li>
|
|
<li>More external parsers. YaCy now supports tar, zip, gzip, bzip, rss, rtf, pdf, doc. To use these parsers, an additional libx-library must be installed which comes separately to the YaCy core distribution.</li>
|
|
<li>Enhanced Shutdown procedure: many unnesessary threads had been removed, a shutdown hook had been added. Missing file closings hat been added. The new index caching method flushes the cache faster.</li>
|
|
<li>Added support for localization: it is now possible to extend YaCy with localization data; added languages can be accessed with the new Language-Menu</li>
|
|
</ul>
|
|
|
|
<br><p>v0.37_build20050502

|
|
<li>overall speed enhancements:</li>
|
|
<ul>
|
|
<li>new Thread-Pools and performance enhancements from Martin Thelian: much faster http-server and more responsive web interface</li>
|
|
<li>fixed bug in database caching that prevented from caching at all; now database much faster. This also speeded up proxy mode (must read http-header from database)</li>
|
|
<li>modified thread control for non-blocking dequeueing</li>
|
|
<li>increased cache memory settings</li>
|
|
</ul>

|
|
<ul>
|
|
<li>New Crawling-Profiles for Crawl-Threads
|
|
<ul>
|
|
<li>every crawl start now defines it's own crawl job; new crawls do not interfere with previously started and still running jobs; all started jobs may run concurrently</li>
|
|
<li>new crawl properties: accept urls containing '?'; flag for storage of pages in proxy cache; flags for local and remote indexing</li>

|
|
<br><p>v0.30_build20041125
|
|
<ul>
|
|
<li>Implemented Remote Crawling
|
|
<ul>
|
|
<li>Every Senior and Principal Peer may now start Remote Crawls: The initiating peer starts with the crawl and may assign URLs to qualified other peers. Those peers load the assigned resource, index them and return the index statistics back to the initiator. Executing peer may only be a Senior or Principal peer.</li>
|
|
<li>Extended URL management: URLs are now organized in three different sets: Noticed-URLs (not loaded but possibly queued for crawling), Error-URLs (not loaded but may be re-loaded to avoid index loss in case of temporary target server downtime or network problems) and Loaded-URLs. The Loaded-URLs are again divided into six categories:</li>
|
|
<ol>
|
|
<li>remote index: retrieved by other peers</li>
|
|
<li>partly remote/local index: result of search queries</li>
|
|
<li>partly remote/local index: result of index transfer (to be implemented soon)</li>
|
|
<li>local index: result of proxy fetch/prefetch</li>
|
|
<li>local index: result of local crawling</li>
|
|
<li>local index: result of remote crawling requests</li>
|
|
</ol>
|
|
<li>New monitoring pages: Local Index Monitor for results of LURL's (see above), cases 1-5 and the Global Index Monitor for case 6. Because the results of global crawls are not personal to the peer owner, the monitor page is not protected.</li>
|
|
<li>Options to allow or disallow remote crawling; either as initiating or executing peer.</li>
|
|
<li>Idle/Due-Time - management for each peer: to organize remote-crawl load-balancing, a delay time is used to schedule remote crawls. The seed management was extended to store and maintain these delay times.</li>
|
|
</ul>
|
|
</li>
|
|
<li>Proxy Performance Enhancements
|

</li>
|
|
<li>Implemented Shut-Down Procedure
|
|
<ul>
|
|
<li>Integrated notifier procedure in all threads.</li>
|
|
<li>The application now creates a file 'yacyProxy.control' after start-up.</li>
|
|
<li>To stop the yacyProxy, remove the control file.</li>
|
|
<li>Integrated a 'Shutdown' - button on the 'Status'-page which also triggers shut-down</li>
|
|
<li>After shut-down is initiated the application first processes all scheduled crawling- and indexing tasks which may last some minutes in the worst case.</li>

<li>Integrated monitoring interface for prefetch/crawling activities.
|
|
The user can now observe the crawling and indexing activity in detail.
|
|
There is also a report page that lists all newly indexed pages with the option
|
|
to delete these indexes again. The interface also reports the initiator
|
|
of the crawling/indexing tasks which can be currently either the prefetch mechanism
|
|
or explicit crawling requests. In future releases the initiator may also refer to
|
|
remote crawling requests.
|

</li>
|
|
<li>New caching procedure for database requests on file-system level.
|
|
</li>
|
|
<li>Extended blacklist url matching: parts of a domain may now be matched with wildcards '*'. (the URL's path may be matched with regular expressions)</li>
|
|
<li>The application will be re-named. Many parts now refer to the new application name 'yacy', but not all.</li>

|
|
<ul>
|
|
<li>Search results are now searched again for characteristic word patterns.

The patterns are statistically evaluated and are used to generate
|
|
"search associations",

</li>
|
|
<li>Parallelized peer propagation process. This results in very rapid bootstraping.
|

<li>Integrated new 'score' library for rapid element sorting - used for search
|
|
patterns and rapid bootstraping. May help in future releases to speed up indexing.

<br><p>v0.26_build20040916
|
|
<ul>
|
|
<li>Introduced new 'virtual' TLD (top-level-domain) '.yacy' that the proxy resolves into the peers IP and port numbers:</li>
|
|
<ul>
|
|
<li>Every yacy-peer can now be contacted using the peer's name as domain name:
|
|
Proxies users can obtain any other proxy-hosted pages using the url 'http://<peer-name>.yacy'.</li>
|
|
<li>Implemented sub-level domains for yacy TLD's: they are matched to subdirectories of the peer's individual web root HTDOCS. (see below)</li>
|
|
</ul>
|
|
<li>Support for individual web pages:</li>
|
|
<ul>
|
|
<li>Every proxy host can serve it's individual web page. We implemented two paths for each server: one default path pointing to <application-root>/htroot for administrative pages and an alternative path for individual use at <application-root>/DATA/HTDOCS.</li>
|
|
<li>The individual web pages may be accessed either using the new '.yacy' TLD's through another proxy, or optionaly by using the peer's IP:port address. The recommended default address of a proxy is 'http://www.<peer-name>.yacy', which is mapped to <application-root>/DATA/HTDOCS/www/. </li>
|
|
<li>Integrated an upload/download interface for individial web pages: additional accounts for uploaders and downloaders ensure appropriate authorization. The file-sharing web space can be browsed with an directory servlet. A default sub-domain is assigned to 'http://share.[peer-name].yacy', which is mapped into <application-root>/DATA/HTDOCS/share/.</li>
|
|
<li>Web clients not using the proxy may contact the new individual default subdomains using the URLs http://<peer-IP>:<peer-port>/www/ and http://<peer-IP>:<peer-port>/share/.
|
|
</ul>
|
|
<li>Several Bug-fixes:</li>
|
|
<ul>
|
|
<li>Date bug appearing when accessing the proxy httpd with the proxy.</li>
|
|
<li>Additional Time-out catch-up at httpc when a file is submitted without length tag. Also extended general retrieve - time.out.</li>
|
|
<li>Terminal line restriction of 1000 bytes was too tight (cookies may have 4kb length).</li>
|
|
<li>Introduced global general time measurement for peer synchronization and balanced hello - round-robin.</li>
|
|
</ul>
|
|
<li>Enhanced proxy-proxy - mode: 'no-proxy' settings as list of patterns to exceptional dis-allow usage of remote proxies.</li>
|
|
<li>Implemented multiple default-paths for URLs pointing to directories.</li>
|
|
<li>Re-design of front-end menu structure.</li>
|
|
<li>Integrated Interface for principal configuration in Settings page</li>
|
|
<li>Re-named the release: integrated YACY name to emphasize that the proxy is mutating into the YACY Search Engine Node</li>

<li>New 'Cache' Menu item: The proxy cache can now be inspected. It shows a directory list with http response headers and content to each file in the proxy cache.</li>
|

<li>double links / unchecked '#', headlines wrong</li>
|
|
<li>httpd-speedup (no more temporary files, template prefetch without double-load)</li>
|
|
<li>much better Bootstraping and more intelligent yacy-peer updating</li>
|

</ul>
|
|
|
|
<br><p>v0.22_build20040711
|
|
<ul>
|
|
<li>More security bug fixes (dementia accountia, '..' usage in server path, server blacklist too tight for local clients)</li>
|
|
<li>Another advance in better peer distribution and recognition (distinguishes between 'real' disconnected peers and 'hearsay' disconnected peers. Keeps track of online time. No preferences of principal peers in link distribution)</li>
|
|
<li>An option to switch the peer to online mode without using the proxy. This makes life much easier for newbie's.</li>
|
|
<li>A new message function. Within the Network page, one can hit the 'm' and may then send a message to the other peer. The owner of that
|
|
peer can read the message in his/her private message inbox. This function is only in alpha statdium; it works only in rare cases and
|
|
we don't know why. Only for testing.</li>
|
|
<li>Cleaned up the mess of different database and configuration files. All run-time data is now accumulated in the new folder 'DATA'. If you previously generated an index and want to migrate, you simply need to put your old PLASMADB folder into the new DATA folder.</li>
|
|
<li>Clean up of the source mess and partition of them into separate packages</li>
|
|
<li>Some design enhancements of the online interface</li>
|
|
</ul>
|
|
|
|
<br><p>v0.21_build20040627
|
|
<p>After an announcement on freshmeat.net we got many hits in the newly build p2p-network. We learned from the p2p-propagation behavior and
|
|
implemented a lot of new routines to stabilize the YACY network.
|
|
<ul>
|
|
<li>Better peer analysis, statistics, propagation/distribution (more properties and bug fixes).</li>
|
|
<li>No more JavaScript in online Interface. New template logic for httpd and new online interface look-and-feel, using the new features.</li>
|
|
<li>New FAQ in documentation.</li>
|
|
<li>Protection against hacker and virus attacks: new self-configuring client-IP blocking in serverCore.java</li>
|
|
<li>More information and warnings about security settings to the operator to protect the own peer</li>
|
|
<li>Network statistics and monitor shows status of remote peers and the distributed index</li>
|
|
</ul>
|
|
|
|
<br><p>v0.20_build20040614
|
|
<p>The first step into the p2p-world: introduction the YACY (yet another cyberspace) p2p network propagation and information wares distribution system. YACY enables in this release a rudimentary index exchange so that you can use YACY to bootstrap a world-wide distributed search engine.</p>
|
|
<ul>
|
|
<li>Added status page on web interface and automatic opening of web browser on status page. Can be switched off on the satus page.</li>
|
|
<li>Implemented still missing element removal and AVL balancing for element insterts in the kelondro database. This ensures logarithmic efforts on database access, which influences the proxy and the search service. Now only AVL balancing after removal must be implented, but it's missing is not critical.</li>
|
|
<li>Added blacklist enhancements and web interface for blacklist editing from Alexander Schier.</li>
|
|
<li>More and better documentation.</li>
|
|
<li>Many minor bug fixes, i.e. non-cacheabilty of web interface, exception catch-up on startup when proxy is used before coloured lists are loaded.</li>
|
|
<li>First p2p elements implemented: every peer on startup looks for other peers and announces it's own startup. The function does not yet actively implement an index exchange, but can repond to remote index queries.</li>
|
|
</ul>
|
|
|
|
<br><p>v0.16_build20040503
|
|
<p>This release is a major step to make the proxy enterprise-ready: we introduced several security mechanism and access
|
|
restrictions for the proxy and the server. Every security setting can be configured through a web page. Thanks to the new
|
|
HTTPS proxy, the proxy can now be considered as 'complete'.
|
|
<ul>
|
|
<li>implemented a HTTPS proxy, sharing the same proxy port with http;
|
|
this does not help for more/better indexing since the SSL data is simply passed through.
|
|
But we can now state to be a 'full' http and https proxy, usable in enterprise environments and internet cafe's.</li>
|
|
<li>two security layers for web server and proxy access: implemented Client-IP - filtering, which adds a virtual Firewall to
|
|
the application. Every client that does not match the client-IP-filter is blocked. The second layer is a PROXY password
|
|
protection. All attributes can be configured through a new web page at http://localhost:8080 (standard configuration).</li>
|
|
<li>to protect the configuration pages of the web server, we introduced a password protection for special pages on the web server.
|
|
Every page that ends with '_p.html' has a protection; the corresponding account can also be set through the local web server.
|
|
Users shall be encouraged to set this administration account first.</li>
|
|
</ul>
|
|
|
|
<br><p>v0.15_build20040318
|
|
<ul>
|
|
<li>Extensive code re-engineering</li>
|
|
<ul>
|
|
<li>Inserted and further generalized the proxy's genericServer into the AnomicFTPD project. After further enhancements within that project,
|
|
it was re-inserted in the HTTPProxy. The Switchboard interface now belongs to the genericServer, which is now called the serverCore.</li>
|
|
<li>Removed the old html parser and replaced it by the new htmlFilter library, which now parses the html files during reading from
|
|
the remote server. Real-time parsing during streaming html pages is done extremely fast and does not slow down file passing through
|
|
the proxy. The new htmlFile provides a filter interface, which is now used to filter out content that is defined by keywords.
|
|
Currently the bluelist 'httpProxy.blue' is used to define these words.</li>
|
|
<li>Re-engineered the crawler interface and implemented a crawler. Since the crawler does not work in all cases, it is still
|
|
disabled in this release. You can switch it on by setting the prefetchDepth in the configuration file httpProxy.init</li>
|
|
</ul>
|
|
<li>Implemented a 304 response. This speeds up all responses in the case of a cache hit combined with a conditional request.
|
|
Since this combination is fairly common, it noticeable speeds up the proxy.</li>
|
|
<li>New documentation design</li>
|
|
<li>New Search Page design</li>
|
|
</ul>
|
|
|
|
|
|
<br><p>v0.14-build20040213
|
|
<ul>
|
|
<li>More Structure to the whole system to lay the basis for the Crawler</li>
|
|
<ul>
|
|
<li>The new structure will distinguish between the <i>httpd</i> with it's servlets, the file-servlet and proxy-servlet;
|
|
the <i>crawler</i> which also holds responsibility for the http cache that is used by the http proxy and the <i>indexing</i>
|
|
engine 'PLASMA', which is again accessed by the http file server. But even with the crawler concept on board here, we still don't have prefetch now.</li>
|
|
<li>Moved plasmaTextProvider to httpCrawlerScraper, httpdProxyCache to httpCrawlerCache and httpdSwitchboard to httpCrawlerSwitchboard</li>
|
|
<li>New configuration value proxyCacheSize: limits the memory amount of the cache; if the cache exceeds this value the oldest entries are deleted</li>
|
|
</ul>
|
|
<li>Bug fixes:</li>
|
|
<ul>
|
|
<li>Found and eliminated nasty bug that prevented using yahoo mail. (they send several cookies at once)</li>
|
|
<li>No more indexing of URLs with 'cgi' in name or ending with '.js', '.ico', or '.css' (checking content-type for 'text' is not enough; some servers do not transfer right value)</li>
|
|
<li>Fixed search for words containing numbers and german Umlaute</li>
|
|
<li>adopted acrypt.java to no using javax.crypt, this was not supported by debian blackdown java 1.3.1. Furthermore, removed -server - flag from httpProxy.sh, that also made blackdown to crash. (you probably want to insert that flag again in your installation)</li>
|
|
</ul>
|
|
<li>The proxy can now be configured to access another proxy</li>
|
|
</ul>
|
|
|
|
<br><p>v0.13-build20040210
|
|
<ul>
|
|
<li>Bug fixes:</li>
|
|
<ul>
|
|
<li>removed forced unzipping for special cases: either if the file to be transported is 'naturally' in gzip format (.gz, .tgz and .zip) or if zipping would not make sense because it would not yield any compression, as for images. Now the 'Accept-Encoding', created by the browser and send to the server has omitted gzip attributes in this cases. This should lead to less overhead (no gzip en/de-coding) and thus to more speed.</li>
|
|
<li>now transport of httpc failure response body (especially 404; seemed to be unneccesary, but is not)</li>
|
|
<li>search result bug (mixed up appearence) removed</li>
|
|
</ul>
|
|
<li>Performance and structure enhancements:</li>
|
|
<ul>
|
|
<li>Extended database capabilities to hold content of dynamic size; new files kelondroRA.java, kelondroAbstractRA.java, kelondroFileRA.java, kelondroDyn.java</li>
|
|
<li>Used new database features to store the response header information for all files in the cache into one database file. This saves 50% of the number of files in the cache (no more need for the .header - files)</li>
|
|
<li>Implemented a scheduling that moved the time of cache creation into an proxy-idle - time. This reduces the file operation on a single user system by 50% during web page retrievement.</li>

<ul>
|
|
<li>integrated blacklist 'httpProxy.black' idea and data from Alexander Schier: forced 404 response for blacklisted hosts. This can be used to 'switch off' specific domains, especially AGIS servers. Can also be used for child protection/parental control. Does not filter content!</li>
|
|
<li>cache write bug if same file and directory name is used (can be done in URL, but not in cache file system) removed. </li>
|
|
<li>detailed 404 debugging response in case of failure</li>
|
|
<li>new config value maxSessions for limit the number of concurrent connections to the proxy</li>
|
|
<li>Host property bug in httpc for HTTP/1.1 servers removed: now better access to more servers</li>
|
|
</ul>
|
|
<li>enhanced indexing and searching:</li>
|
|
<ul>
|
|
<li>implemented rudimentary ranking and ordering of search results either by quality or by date</li>
