2010-05-06 Marek Habersack * OutputCacheModule.cs: added a 2.0 internal property to return the internal provider used in this profile. * OutputCache.cs: added internal RemoveFromProvider method to remove items from the indicated provider. 2010-02-23 Marek Habersack * CachedVaryBy.cs: made serializable for 4.0+ (necessary for extensible output caching) 2010-02-03 Marek Habersack * OutputCache.cs: DefaultProviderName checks if there was any provider configured and, if not, returns a built-in provider's name. * SqlCacheDependencyAdmin.cs: added * OutputCacheProviderCollection.cs: added * OutputCacheProvider.cs: added * OutputCacheModule.cs: uses the 4.0 extensible output cache provider model now (also internally in the 2.0 profile) OutputCacheProvider is retrieved on every request using HttpApplication.GetOutputCacheProviderName (4.0+). In the 2.0 profile an instance of InMemoryOutputCacheProvider is always returned. * InMemoryOutputCacheProvider.cs: default output cache provider for ASP.NET 4.0, also used internally in the 2.0 profile. * CachedVaryBy.cs: made the generated key shorter * CacheItemPriorityQueueDebug.cs: debugging support for CacheItemPriorityQueue. Most of the code is compiled only when the DEBUG macro is defined. Debugging support includes recording of the queue operations sequence which is output to an XML file on appdomain shutdown. The recorded sequence files can be used to generate NUnit test cases for the priority queue (see ../Test/tools/README) * CacheItemPriorityQueue.cs: rewritten using an array based heap instead of a binary tree based one - implementation is simpler, faster and more elegant. Heap is initially 32 entries long and its size is doubled every time it fills up. After reaching a threshold (8192 entries currently) it is shrunk to the number of items + 1/3 of item count in order to preserve memory. * CacheItem.cs: added a Guid field to easier distinguish items (mostly for debugging purposes) * CacheDependency.cs: minor performance improvements * Cache.cs: better handling of timer periods 2010-01-25 Marek Habersack * SqlCacheDependency.cs: added parameter checks to the constructors. Partially implemented 4.0 method CreateOutputCacheDependency * CacheItemUpdateReason.cs, CacheItemUpdateCallback.cs: added * CacheItem.cs: added OnUpdateCallback field * Cache.cs: implemented support for cache item update callback (3.5+) * AggregateCacheDependency.cs: added undocumented DependencyDispose method override 2010-01-22 Marek Habersack * SubstitutionResponseElement.cs: implemented correct (de)serialization of the Callback delegate. * OutputCache.cs: implemented Serialize, Deserialize, DefaultProviderName and Providers. 2010-01-21 Marek Habersack * DatabaseNotEnabledForNotificationException.cs, OutputCache.cs, FileResponseElement.cs, HeaderElement.cs, IOutputCacheEntry.cs, MemoryResponseElement.cs, OutputCacheProvider.cs, ResponseElement.cs, OutputCacheProviderCollection.cs, SubstitutionResponseElement.cs, TableNotEnabledForNotificationException.cs: added * CacheDependency.cs: default constructor is protected in 4.0 2010-01-06 Marek Habersack * CacheItemPriorityQueue.cs: make sure lastParent is never null if root is not null in Enqueue. Possible fix for bug #567869 2009-12-01 Marek Habersack * Cache.cs: ExpireItems dequeues the next item when a disabled item is found before continuing to look for items to expire. Fixes bug #559470. Patch from Adriaan van Kekem , thanks. 2009-10-21 Marek Habersack * CacheItemPriorityQueue.cs: lock the queue on enqueue/dequeue 2009-10-20 Marek Habersack * OutputCacheModule.cs: keysCache and entriesToInvalidate dictionaries are allocated only when they are required. BuildManager's RemoveEntry envent is subscribed to only if cache actually has some entries. Added support for post-cache substitution. * CachedRawResponse.cs: data is stored in a list of DataItem instances instead of just in a single buffer. This enables support for post-cache substitution. 2009-10-05 Marek Habersack * Cache.cs: if item expiration time exceeds the maximum value Timer accepts, use the latter - item will expire properly anyway, as the timer will be rescheduled for the item's expiration time once that item is bubbled to the top of the priority queue. Fixes bug #544171 2009-09-26 Marek Habersack * CacheItemPriorityQueue.cs, CacheItem.cs, CacheItemEnumerator.cs: added * Cache.cs: factored out CacheItem and CacheItemEnumerator to separate files. Use reader-writer locks instead of Monitor. Added two 3.5sp1 properties - EffectivePrivateBytesLimit and EffectivePercentagePhysicalMemoryLimit. Added support for disabling cache item expiration. One timer is used to expire all timed items (instead of one timer per item). Timed items are kept in a priority queue. 2009-03-03 Marek Habersack * CachedRawResponse.cs: headers are stored in NameValueCollection now. 2009-01-09 Marek Habersack * Cache.cs: System.Threading.Timer.Change takes a long, not an int. The maximum value of sliding expiration is 365 days (31536000000ms) which fits within the value range of long. The previous cast to int might yield negative values in certain situations which was the reason for bug #464221. Fixes bug #464221 2008-10-21 Marek Habersack * OutputCacheModule.cs: seal the class. Made OnRawResponseRemoved a static method. * CachedVaryBy.cs: seal the class. Use portable line terminators instead of literal '\n'. * Cache.cs: seal the CacheItem and CacheItemEnumerator classes. * CacheDependency.cs: dispose the associated dependency in the DependencyDispose method. * CachedRawResponse.cs: seal the class 2008-10-15 Marek Habersack * OutputCacheModule.cs: do not take any action if Response returns null from GetCachedResponse. 2008-09-30 Juraj Skripsky * CachedRawResponse.cs: Don't allocate a 32k buffer that is never used. Fixes enhancement bug #430963. 2008-09-29 Marek Habersack * OutputCacheModule.cs: invalidate cache entries when the corresponding source file (.as?x) is recompiled by hooking up to System.Web.Compilation.BuildManager's build cache entry removal event. Fixes bug #429926 2008-09-26 Juraj Skripsky * OutputCacheModule.cs: Consistently use InternalCache for CachedRawResponse items and Cache for CachedVaryBy items. Partial fix for bug #429926. 2008-08-11 Marek Habersack * Cache.cs: dispose item timer when removing an entry. Fixes bug #416076. Patch provided by Adriaan van Kekem , thanks! Pass onRemoveCallback along in Insert. Fixes bugs #324528 and #382644. Patch provided by Juraj Skripsky , thanks! 2008-06-18 Marek Habersack * SqlCacheDependency.cs: added 2008-05-30 Marek Habersack * CacheDependency.cs: do not use synthetized event accessors (to avoid locks). 2008-05-23 Marek Habersack * Cache.cs: optimize lock usage 2008-04-28 Marek Habersack * Cache.cs: refactoring - move the timeout setting code to separate methods, so that it can be accessed from outside the class. Fixes bug #382644 2008-03-18 Geoff Norton * Cache.cs: MS allows calling Insert in a removed handler, we need to avoid double locking here otherwise the Insert will never succeed. 2008-02-26 Kornél Pál * CachedRawResponse.cs, OutputCacheModule.cs: Don't add Date header because servers usually add a Date header that would result in duplicate Date header sent to the client. Fixes bug #363404. 2007-12-31 Vladimir Krasnov * Cache.cs: added DependencyCache property, a cache object for creating dependencies 2007-12-19 Juraj Skripsky * Cache.cs: Replace periodic timer (60s) with per-cache-item expiration timers. 2007-08-17 Marek Habersack * CacheDependency.cs: use DependencyChanged as a list of events. OnChanged now calls OnDependencyChanged, to notify AggregateCacheDependency that it has changed. Fixes bug #82419. 2007-08-14 Marek Habersack * AggregateCacheDependency.cs: propagate changes in any child dependencies to the base class. 2007-06-25 Juraj Skripsky * Cache.cs: Re-introduce "InvokePrivateCallbacks" accidentally removed in r80321. 2007-06-20 Marek Habersack * OutputCacheModule.cs: use Context.InternalCache. * Cache.cs: 2.0 profile uses generic containers to keep the cache entries. Gotten rid of the InsertPrivate and InsertInternal methods. The latter was moved to one of the Insert overloads. Private entries are no longer handled specifically, because the internal cache is now kept in a separate object. Iterate over the entries when filling the ArrayList in the 2.0 profile to avoid type cast exceptions. 2007-05-03 Igor Zelmanovich * AggregateCacheDependency.cs: * CacheDependency.cs: added missing API. 2007-04-10 Marek Habersack * CacheDependency.cs: add the NotifyFilters.Size to the watcher flags, so that we watch for modifications to a file when using Linux inotify. 2006-11-29 Marek Habersack * CachedVaryBy.cs: Make sure that the vary:* header is generated only when allowed under the 2.0 profile. 2006-11-25 Marek Habersack * AggregateCacheDependency.cs: A small code optimization. 2006-11-14 Marek Habersack * Cache.cs: * CacheDependency.cs: * AggregateCacheDependency.cs: implement this one. 2006-09-11 Andrew Skiba * CacheDependency.cs: ifdef TARGET_JVM 2006-08-03 Gonzalo Paniagua Javier * CacheDependency.cs: * Cache.cs: check dependencies on other cache keys. Fixes bug #79002. 2006-03-18 Robert Jordan * OutputCacheModule.cs: invoke the validation callbacks of HttpCachePolicy. Fixes bug #77825. 2006-03-14 Robert Jordan * CachedVaryBy.cs: Fixed VaryByParam="*". Replaced request.Param with QueryString and Form lookups. Made the param name output case insensitive. Fixes bug #77757. 2005-10-24 Gonzalo Paniagua Javier * Cache.cs: new internal method. 2005-09-08 Eyal Alaluf * OutputCacheModule.cs: Use C# 1.0 style of delegate instantiating. Needed to compile Grasshopper (TARGET_J2EE) which uses MS C# 1.0 compiler and does not use msc. 2005-09-02 Gonzalo Paniagua Javier * Cache.cs: ignore exceptions thrown by removed item callbacks. 2005-09-02 Sebastien Pouliot * Cache.cs: Added security permissions with Minimal level for AspNetHostingPermissionLevel (only LinkDemand as the class is sealed). * CacheDependency.cs: : Added security permissions with Minimal level for AspNetHostingPermissionLevel (note class is sealed only in 1.x). 2005-09-01 Eyal Alaluf * CacheDependency.cs: TARGET_J2EE fixes. 2005-08-20 Gonzalo Paniagua Javier * CacheDependency.cs: add missing ctor. 2005-08-15 Jackson Harper * CacheItemPriority.cs: * CacheItemRemovedCallback.cs: * CacheItemRemovedReason.cs: New implementations. 2005-07-30 Miguel de Icaza * OutputCacheModule.cs: Make synchronous. 2005-07-15 Lluis Sanchez Gual * Cache.cs: New implementation. * CacheDependency.cs: New implementation. 2005-06-25 Gonzalo Paniagua Javier * Cache.cs: added new InsertPrivate overload. 2005-06-25 Gonzalo Paniagua Javier * Cache.cs: * CacheEntry.cs: style. Removed doc. comments. 2005-06-08 Ilya Kharmatsky * CacheDependency.cs - added TARGET_JVM directives in places, where file watching is using (Mainsoft's implementation currently doesn't support the feature). 2005-05-09 Gonzalo Paniagua Javier * CacheEntry.cs: credits for this patch should go to mcs. it catched that the code after 'if ((_enumFlags & Flags.Removed) != 0)' was unreachable. 2005-04-28 Gonzalo Paniagua Javier * ExpiresBuckets.cs: * Cache.cs: * CacheExpires.cs: fix NullReferenceException thrown sometimes when using sliding expiration and under high load. Patch by Eyal Alayuf from Mainsoft. 2005-04-20 Gonzalo Paniagua Javier * CacheDependency.cs: remove warnings. 2005-04-01 Gonzalo Paniagua Javier * CachedVaryBy.cs: fixed VaryByParam and wildcard (*). Patch by Ilya Kharmatsky (Mainsoft) that fixes bug #73981. 2005-04-01 Lluis Sanchez Gual * CachedRawResponse.cs: Fix warning. 2004-11-08 Gonzalo Paniagua Javier * CacheEntry.cs: convert the external DateTime to GMT, as everything else uses that timezone. Fixes bug #69194. 2004-10-03 Ben Maurer * Cache.cs, CacheEntry.cs, CacheExpires.cs, ExpiresBuckets.cs: use UtcNow rather than Now. 2004-05-27 Patrik Torstensson * ExpiresBucket.cs (FlushExpiredItems): fix csc and a typo bug 2004-05-27 Patrik Torstensson * CacheEntry.cs,CacheExpires.cs,ExpiresBucket.cs, Cache.cs : Fixed deadlock issues, fixed items not correctly being flushed, fixed update of item when expiration has been updated more than 1 min (placed in wrong bucket), fixed deadlock during cache callback when item is removed due to expiriation. Rewrite of locking handling in Cache class, leading to better performance and less bugs. This rewrite is due to a number of bugs found in the output caching during load (leading to memory leaks and deadlocks) 2004-05-16 Patrik Torstensson * ExpiresBucket.cs: Style changes plus; (Update): Fixed possible lock bug (bug 54531) (Expand): remove lock optimization due to it can cause newly added items to be lost. (Remove): fixed possible lock bug. 2004-04-16 Gonzalo Paniagua Javier * Cache.cs: fix from Jan Jaros for NullRef (bug #56996). 2004-04-07 Lluis Sanchez Gual * Cache.cs, CacheEntry.cs, ExpiresBuckets.cs: The value to use to specify infinite timeout in ReaderWriterLock is -1, not 0. 2004-03-19 Gonzalo Paniagua Javier * Watcher.cs: Removed file. Jackson made it obsolete and already removed it from the .sources file. 2004-02-09 Jackson Harper * ExpiresBucket.cs: Remove duplicate code. Fixes bug #54031. 2004-02-09 Jackson Harper * Cache.cs: Close entries that are removed. * CacheDependency.cs: Use FileSystemWatcher instead of custom Watcher for file dependencies. * OutputCacheModule.cs: Make the varyby objects dependent on the cached page. 2004-02-05 Jackson Harper * CacheDependency.cs: Handle cache keys that have not been added to the cache yet. 2004-02-02 Jackson Harper * OutputCacheModule.cs: We can use file dependancies now. 2004-01-14 Jackson Harper * Cache.cs: Return null when items are expired but have not been removed yet. * OutputCacheModule.cs: Handle sliding expirations. Remove hacks checking if the item is expired, the cache no longer returns expired items. 2004-01-14 Jackson Harper * Cache.cs: When using sliding expiration update the cache objects expires time as well as the expires entry expire time because the objects expire time is checked when objects are pulled out. This fixex bug #52778. 2004-01-11 Jackson Harper * OutputCacheModule.cs: Remove varyby objects when there are no more raw responses that belong to them. * CachedRawResponse.cs: Keep a reference to the VaryBy object that this response belongs to this is so the varyby can be cleaned up. * CachedVaryBy.cs: Keep a reference to the keys that belong to the varyby and a reference to the varyby's key. 2004-01-04 Jackson Harper * OutputCacheModule.cs: Dont cache items when trace is enabled. 2004-01-04 Jackson Harper * OutputCacheModule.cs: Update the date header value. * CachedRawResponse.cs: Expose a ref to the date header, so it can be easily set/updated. Remove unused methods and vars. 2004-01-04 Jackson Harper * CacheDependency.cs: Copy all the entries into the entries array, set on removed callback for items that we are dependent on. * Cache.cs: Add method to get CacheEntry objects. * OutputCacheModule.cs: Make raw repsonse entries dependent on their varyby param entries. 2004-01-04 Jackson Harper * OutputCacheModule.cs: VaryBy keys now need the HttpContext not just the request. * CachedVaryBy.cs: Handle vary by headers, and vary by custom. 2004-01-03 Gonzalo Paniagua Javier * ExpiresBuckets.cs: set _intPos when expanding the array. Fixes bug 52541. Patch by Jan Jaros (mono-bug@jerryweb.info). 2003-11-21 Jackson Harper * OutputCacheModule.cs: Only cache a page if it has a 200 status code. Fix tabbing. * CachedVaryBy.cs: Give raw response keys a name, use the httpmethod in the key, and delimit items with \n so it is easier to read when debugging. 2003-11-21 Jackson Harper * OutputCacheModule.cs: Store a CachedVaryBy object for each cached page. Then store a CachedRawResponse for each combination of varried parameters for a page. * CachedRawResponse.cs: Do not need to store param values anymore those are stored in the CachedVaryBy now. Get the content length so we dont send back the entire buffer. * CachedVaryBy.cs: New file - holds the varyby data for a page, and a method to generate a key based on params. Right now this only works with VaryByParams. TODO: support VaryByHeaders and VaryByCustom. 2003-11-20 Jackson Harper * Cache.cs: New method so non public cache items can be added. * CachedRawResponse.cs: New file - A snapshot of a response that is stored in the cache and can be used to create a new response. * OutputCacheModule.cs: Module for inserting and retrieving responses from the cache. 2003-04-09 Gonzalo Paniagua Javier * CacheDependency.cs: * CacheEntry.cs: * Watcher.cs: added a FileSystemWatcher-like class for dependency checking. 2003-03-13 Gonzalo Paniagua Javier * Cache.cs: * CacheDefinitions.cs: * CacheDependency.cs: * CacheEntry.cs: * CacheExpires.cs: * ExpiresBuckets.cs: reformatted, make class status page happier. Does not work yet (wait for the next patch). 2002-12-27 Daniel Cazzulino * CacheEntry.cs: several changes. New constants, use of constants defined in Cache.cs, modified locks to optimize perf. Fixed property sets which weren't using the keyword value to set the new values (don't know how this worked before!). * Cache.cs: changed singleton implementation to only create the object when actually used. Changed Insert overloads to use constants defined instead of hard values. * ExpiresBuchets: major changes. All locking now uses ReaderWriterLock class. Bucket now efectively reuses free indexes from removed items to avoid unnecessary expansions. Expansion now uses Array.CopyTo to add elements to the new list. Added private Int32Collection to handle int indexes efficiently (thanks Shawn Van Ness). See comments there. 2002-10-08 Gonzalo Paniagua Javier * Cache.cs: little fixes. 2002-07-28 Gonzalo Paniagua Javier * CacheDefinitions.cs: fixed a couple of enums. * CacheDependency.cs: the class is sealed. 2002-06-11 Gonzalo Paniagua Javier * CacheDependency.cs: fixed a couple of typos and don't throw NotImplementedException in constructors. 2001-12-21 Gaurav Vaish * CacheDependency.cs: Some unimplemented methods to make build 2001-07-20 Patrik Torstensson (Patrik.Torstensson@labs2.com) * Cache.cs: Implemented. (90% ready) * CacheDefinitions.cs: Implemented. * CacheDependency.cs: Added. (20% ready) * CacheExpires: Implemented. * CacheEntry.cs: Implemented. (95% ready, going to be changed due to CacheDependecy support) * ExpiresBuckets.cs: Implemented.
