	We still have a 65535 limit on the length of a pattern and the
	number of groups in a pattern.
	* compiler.cs (PatternCompiler.EmitCount): New.  Emits an int as
	two ushorts into the program stream.
	(EmitInfo, EmitRepeat, EmitFastRepeat): Use it to emit integers
	rather than shorts.
	* interpreter.cs (Intepreter.ReadProgramCount): Read an int
	emitted into the program stream.
	(Interpreter): Use it.  Update counts.
	(Interpreter.Eval) [OpCode.Repeat, OpCode.FastRepeat]: Likewise.

	(Group.IsComplex, Alternation.IsComplex): Move ...
	(CompositeExpression.IsComplex): ... here.

	tail operation has a 'negate' flag, avoid the "match next char"
	optimization.

	Fix #69269
	* arch.cs (OpCode.NotCategory): New.  Stands for matching a
	character _not_ from the given category.
	* debug.cs (DisassembleBlock): Handle it.
	* compiler.cs (ICompiler.EmitNotCategory): New.
	(Compiler.EmitNotCategory): New.  Emit OpCode.NotCategory.
	* syntax.cs (CharacterClass.Compile): Don't conflate negation of

	EmitNotCategory.
	* interpreter.cs (Interpreter.Eval): Pass OpCode.NotCategory to
	EvalChar.
	(Interpreter.EvalChar): Handle it.

2006-04-06  Raja R Harinath  <rharinath@novell.com>

	Fix #77487
	* interpreter.cs (Eval) [Until, FastUntil]: Set 'deep' to null
	when evaluating the tail.  Ensure that backtracks don't confuse
	the recursion vs. iteration detector.

2006-04-03  Raja R Harinath  <rharinath@novell.com>

	* interpreter.cs (Eval) [Until, lazy]: Avoid extra evaluation on a
	degenerate match.

2006-03-30  Raja R Harinath  <harinath@gmail.com>

	Fix #77626
	* parser.cs (Parser.ParseCharacterClass): Don't automatically
	assume there's a range when we see '-'.  Ensure that we have seen
	at least one other character, and that we aren't already parsing a
	range.  Handle some more errors.

2005-12-19  Kornél Pál  <kornelpal@hotmail.com>

	* Regex.cs: Added support for regular expressions compiled to
	  assemblies by compiling the pattern. This solution ignores existing

2005-11-17  Sebastien Pouliot  <sebastien@ximian.com> 
 
	* Match.cs: Removed the ": base ()" on the private ctor as it is
	unrequired and cause an extra public ctor to added (bug #76736).
	* MatchCollection.cs: Add missing virtual to indexer property.

2005-09-23  Raja R Harinath  <rharinath@novell.com>

	Fix #72152, #72989.
	* interpreter.cs (Interpreter.Eval) [OpCode.Until]: Avoid some
	cases of recursion when dealing with eager quantifiers too.  We

	implement backtracking in eager quantifiers.

2005-09-21  Raja R Harinath  <rharinath@novell.com>

	* regex.cs: Remove.  Split into ...
	* MatchEvaluator.cs, Regex.cs, RegexCompilationInfo.cs,	
	RegexOptions.cs: ... these.  Now every publicly exposed type in
	this namespace has its own file.

2005-07-21  Florian Gross  <flgr@ccan.de>

	* Fixed a bug in category.cs that caused ECMAScript \d to fail.

	Make even more lazier.
	* MatchCollection.cs (TryToGet): Don't generate match i+1 when

	(FullList): New helper property.  Ensures the list is fully populated.
	(Count, CopyTo): Use it.
	(Enumerator.Current): Update to new post-conditions of TryToGet.

	beyond the end.

2005-07-08  Raja R Harinath  <rharinath@novell.com>

	* MatchCollection.cs: Convert to incremental mode.

	creating several intermediate strings.  Simplify internal
	intermediate representation.
	(ReplacementEvaluator.EvaluateAppend): New.  Version of Evaluate
	that builds the result directly on a passed-in StringBuilder.
	(ReplacementEvaluator.Evaluate): Just a wrapper around
	EvaluateAppend.

	fail and yet have advanced the pointer.  Append the scanned-over
	portion to the "literal" being built.
	(ReplacementEvaluator.CompileTerm): Don't throw any exceptions.
	If a term cannot be recognized, just return null.

	* compiler.cs (InterpreterFactory.GroupCount): Fix.  The 0'th

	* parser.cs (Parser.Unescape): If the string doesn't contain any
	'\' character, don't allocate a new string.

	* replace.cs (ReplacementEvalutator.Term.AppendResult): Rename

	return a string.
	(ReplacementEvaluator.Evaluate): Update.
	
	* Capture.cs, Group.cs, Match.cs: New files split out of ...
	* match.cs: ... this.  Remove.

2005-02-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* syntax.cs: Applied patch from mei@work.email.ne.jp to fix bug
	#71077.

	* parser.cs: Turns out that \digit sequences are octal sequences
	(no leading zero is needed);  And the three octal digit rule
	applies to the leading zero as well.

	This fixes the Unescape method.

2004-11-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* regex.cs: use NextMatch to move on to the next match. Fixes bug
	#57274.

	prevented any replacements when a postive count is given.
	This also happens in all overloads without count parameter.

2004-10-18 Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* regex.cs: in Replace, when count is negative, replacement continues
	to the end of the string.

	Fixes bug #68398. Patch by Jon Larimer.

2004-06-10  Gert Driesen <drieseng@users.sourceforge.net>

	* RegexRunner.cs: fixed case mismatch of methods

2004-06-10  Gert Driesen <drieseng@users.sourceforge.net>

	internal fields and adding destructor, added MonoTODO attribute to
	fields and method that are not yet implemented, changed not 
	implemented methods to throw NotImplementedException instead of
	Exception, fixed names of field that are serialized

2004-06-06  Jambunathan K <kjambunathan@novell.com>
	
	* parser.cs: Fixed issues with Regex.Unescape() identified as part of
	debugging bug #58256. The original problem reported was about
	inconsistency between the way we treat replacement patterns and the 
	way microsoft treats the replacement patterns in Regex.Replace(). MS
	implementation is buggy and doesn't honour escape sequences in the
	replacement patterns, even though the SDK claims otherwise.

	
2004-06-01  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* syntax.cs: re-applied my patch from 2004-05-27 plus a fix which is

	present.

2004-06-01  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* syntax.cs: reverting my previous patch. It causes bigger problems.

2004-05-27  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* category.cs: added LastValue field to mark the end of enum Category.
	* syntax.cs: in CharacterClass, use Category.LastValue to get the size
	of the array needed. Use a BitArray instead of bool[].
	In AddCategory(), don't set the opposite category as false. Fixes
	bug #59150. All tests pass.

2004-05-25  Jackson Harper  <jackson@ximian.com>

	* parser.cs: Allow creating a regular expression using {,n} as the
	specified. The min bounds is set to -1, I am not completely sure
	if that is what it is supposed to be but MS does not set it to 0
	based on testing. Patch by dave-gnome-bugs@earth.li. Fixes bug #56761.

2004-05-12  Dick Porter  <dick@ximian.com>

	* regex.cs: 
	* quicksearch.cs:

	an empty string must be added to the array of results.

2003-12-15  Sanjay Gupta <gsanjay@novell.com>
	* match.cs: Check for null value before Substring method call.  
	Fixes bug #52034.
