2008-09-26  Juraj Skripsky  <[email protected]>

	* OutputCacheModule.cs: Consistently use InternalCache for
	CachedRawResponse items and Cache for CachedVaryBy items.
	Partial fix for bug #429926.   

2008-08-11  Marek Habersack  <[email protected]>

	* Cache.cs: dispose item timer when removing an entry. Fixes bug
	#416076. Patch provided by Adriaan van Kekem
	<[email protected]>, thanks!
	Pass onRemoveCallback along in Insert. Fixes bugs #324528 and
	#382644. Patch provided by Juraj Skripsky <[email protected]>,
	thanks!

2008-06-18  Marek Habersack  <[email protected]>

	* SqlCacheDependency.cs: added

2008-05-30  Marek Habersack  <[email protected]>

	* CacheDependency.cs: do not use synthetized event accessors (to
	avoid locks).

2008-05-23  Marek Habersack  <[email protected]>

	* Cache.cs: optimize lock usage

2008-04-28  Marek Habersack  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* Cache.cs: added DependencyCache property, a cache object for
	creating dependencies

2007-12-19  Juraj Skripsky  <[email protected]>

	* Cache.cs: Replace periodic timer (60s) with per-cache-item expiration
	timers.

2007-08-17  Marek Habersack  <[email protected]>

	* 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  <[email protected]>

	* AggregateCacheDependency.cs: propagate changes in any child
	dependencies to the base class.

2007-06-25 Juraj Skripsky <[email protected]>

	* Cache.cs: Re-introduce "InvokePrivateCallbacks" accidentally
	removed in r80321.

2007-06-20  Marek Habersack  <[email protected]>

	* 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 <[email protected]>

	* AggregateCacheDependency.cs:
	* CacheDependency.cs:	
	added missing API.	

2007-04-10  Marek Habersack  <[email protected]>

	* 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  <[email protected]>

	* CachedVaryBy.cs: Make sure that the vary:* header is generated
	only when allowed under the 2.0 profile.

2006-11-25  Marek Habersack  <[email protected]>

	* AggregateCacheDependency.cs: A small code optimization.

2006-11-14 Marek Habersack <[email protected]>

	* CacheDependency.cs: ifdef TARGET_JVM

2006-08-03 Gonzalo Paniagua Javier <[email protected]>

	* Cache.cs: check dependencies on other cache keys. Fixes bug #79002.

2006-03-18  Robert Jordan  <[email protected]>

	* OutputCacheModule.cs: invoke the validation callbacks of
	HttpCachePolicy. Fixes bug #77825.

2006-03-14  Robert Jordan  <[email protected]>

	* 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 <[email protected]>

	* Cache.cs: new internal method.

2005-09-08  Eyal Alaluf  <[email protected]>
	* 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 <[email protected]>

	* Cache.cs: ignore exceptions thrown by removed item callbacks.

2005-09-02  Sebastien Pouliot  <[email protected]>

	* Cache.cs: Added security permissions with Minimal level for
	AspNetHostingPermissionLevel (only LinkDemand as the class is sealed).

	for AspNetHostingPermissionLevel (note class is sealed only in 1.x).

2005-09-01 Eyal Alaluf <[email protected]>
	* CacheDependency.cs: TARGET_J2EE fixes.

2005-08-20 Gonzalo Paniagua Javier <[email protected]>

2005-06-08 Ilya Kharmatsky <ilyak-at-mainsoft.com>
	
	* 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 <[email protected]>

	* 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 <[email protected]>

	* ExpiresBuckets.cs:
	* Cache.cs:
	* CacheExpires.cs: fix NullReferenceException thrown sometimes when

	* ExpiresBucket.cs (FlushExpiredItems): fix csc and a typo bug

2004-05-27	Patrik Torstensson <[email protected]>

	* 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 <[email protected]>

	* ExpiresBucket.cs: Style changes plus;

	specify infinite timeout in ReaderWriterLock is -1, not 0.

2004-01-14  Jackson Harper <[email protected]>

	* 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 <[email protected]>

	* 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 <[email protected]>

	* 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

	code. Fix tabbing.

	httpmethod in the key, and delimit items with \n so it is easier
	to read when debugging.
	
2003-11-21  Jackson Harper <[email protected]>

	* OutputCacheModule.cs: Store a CachedVaryBy object for each
	cached page. Then store a CachedRawResponse for each combination
	of varried parameters for a page.

	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.

	not work yet (wait for the next patch).

2002-12-27  Daniel Cazzulino <[email protected]>

	* 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.
