* fetch.php file not existing and devision by zerogweissbach2008-08-05
| | | | | | | | | | | If the cache file does not exist after it should have been generated via an action plugin or via resizing filemtime fails with a file not found. This has to be fixed by @filemtime. Another fix is the check for the $INFO before resizing an image in get_resized. get_croped has already been fixed darcs-hash:20080805132309-f4337-41698af01cf1f3632bd68e1e10724bdffc7c58a3.gz

* X-Sendfile support for fetch.phpAndreas Gohr2007-10-08
| | | | | | | | | | | | This patch enables the use of the X-Sendfile extension offered by certain webservers to deliver static files after running a dynamic script. This combines the flexibility of a PHP file to check for authorization, caching and resizing with the low memory footprint and high performance of static file delivery of the webserver. See http://blog.lighttpd.net/articles/2006/07/02/x-sendfile for details darcs-hash:20071008185019-7ad00-1e6d4768fb60d58955e4253c7786eaf8cf13d0bb.gz

* don't use realpath() anymore (FS#1261 and others)Andreas Gohr2007-09-30
| | | | | | | | | | | The use of realpath() to clean up relative file names caused some trouble in certain setups relying on symlinks or having restricitve file structure setups. This patch replaces all realpath() calls with a PHP only replacement which should solve those problems. darcs-hash:20070930184250-7ad00-512ff04c95f57fc9eaf104f80372237a3c94286f.gz
* better check for images in fetch.phpAndreas Gohr2006-10-18
| | | | | | | | This patch is an enhancement to yesterday's changes. The ability to download external content could be used for XSS attacks, when faking the sent MIME type. This patch adds a check on the received data for valid images. darcs-hash:20061018124942-7ad00-4e8bca7d3877e6a10c348b5d45499cf8adf8b087.gz
* restrict fetch.php's download abilitiesAndreas Gohr2006-10-17
| | | | | | | | | | | | | | | | | | This patch changes fetch.php ability to download external files. It now checks for the returned MIME type and will only download images. For all other MIME types a redirect is sent back to the browser. This reduces the risc of being misused as open proxy. Additionally the download facility is disabled completly by default by setting the fetchsize option to 0. Users who want the feature need to overwrite the option in their local.php. Background: The ability to download external files is needed to resize external images on the server side. When disabled, a redirect is sent to the browser which will download the fullsize image and rescale it on the client side which is more bandwidth and CPU intensive. darcs-hash:20061017175329-7ad00-cd1b1bfa043a04540c51ca8380d28deaa14147d1.gz

* $conf['fetchsize'] addedAndreas Gohr2006-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an option to configure the maximum size for files the fetch.php will ever download. Setting this to 0 completely turns of the caching of external media files. Disadvantages of setting a low or zero fetchsize: * fetch.php needs to download images to be able to resize them. When the used fetchsize prevents the downloading the images can only be resized by the browser which means the browser will need to download the fullsized image first. * If the linked external media files vanishes it will no longer display in the wiki because it is not cached. Advantages of setting a low or zero fetchsize: * fetch.php may be used for a possible denial of service attack by requesting many big external files. * The created cache files may take a lot of space on the server I recommend to leave the setting at 2MB for internal and private wikis and lower the setting to about 200 to 500 Kb for bigger public Wikis. Note: the caching of files uploaded through the media manager is not affected by this setting. darcs-hash:20060615184847-7ad00-04fc39928f7d72e56f5c5e271013ef265436e6c9.gz

* smart cache-control headers for media fetchBen Coburn2006-04-21
| | | | | | | | | | | | | | | | | | | | | The HTTP Cache-Control header output now respects the Dokuwiki media parameters 'cache', 'recache', and 'nocache'. - cache: cachetime or one hour (which ever is larger) - recache: remaining cachetime + 10 seconds so the newly recached media is used - nocache: no caching Notes: - 'proxy-revalidate' should ensure that public caches always revalidate, this will keep caches from (accidentally) ignoring Dokuwiki's ACL rules. - 'no-transform' should keep media from being modified in transit by caches. Impact: Speeds up page layout/display by browsers when they already have the media in their [memory] cache. For example the 2nd time a page is viewed. This also reduces server load by eliminating most of the overhead needed to return '304 Not Modified' responses each time an image is viewed. darcs-hash:20060421025424-05dcb-23ff26c5cb410bcd166299a840f4c500fa0d112e.gz
* bugfix fetch remote media (recache and nocache)Ben Coburn2006-04-21
| | | | | | | | | | | | | | | | | | | | | | | Fixes a major bug in fetching remote media with 'recache' and improves the efficiency of 'nocache'. Recache: - Used to reload the remote media on EVERY request. - Now it behaves as intended and only reloads the remote media into the Dokuwiki cache every $conf['cachetime'] time. Nocache: - No longer stores remote media in the Dokuwiki cache. - No longer loads, saves, and forwards remote media -- just redirects. - No longer resizes images on the server because the cached results can not be reused. Overall this is faster for Dokuwiki. The bandwidth usage for the 3rd party server is the same (less for Dokuwiki). Page loading should also be faster because data is not being forwarded through Dokuwiki (and the 3rd part server's cache control headers will be respected automatically). darcs-hash:20060421012210-05dcb-a6029baa0fad218ace28e0e3c2f442b1ca645a99.gz

* session_write_close added #364andi2005-06-08
| | | | | | | | | | I just learned that PHP does lock it's session objects. This is realy bad if you have multiple images in a page as each one will call fetch.php which locks the session, so everything can only be loaded sequentially. The fix for this is to close the session after using it which is after doing the auth and the breadcrumbs. I added the needed calls everywhere. darcs-hash:20050608213514-9977f-f2dfc467ebbd06406e10e33a386fa1db6cb32dba.gz
