	stream if needed.

2002-11-07  Gonzalo Paniagua Javier <[email protected]>

	* StreamReader.cs: Changed all Encoding.UTF8 to Encoding.UTF8Unmarked.

2002-11-06  Miguel de Icaza  <[email protected]>

	* StreamWriter.cs: Changed all Encoding.UTF8 to Encoding.UTF8Unmarked.

2002-10-31  Dick Porter  <[email protected]>

	* FileStream.cs: Fix buffering properly this time.  Also kludge
	around broken pipe errors, treating them as EOF instead of
	throwing an IO exception.

	* MonoIO.cs: Return the error status in a parameter, as the
	GetLastError() value has long since been blown away if we try and
	look it up in a subsequent internal call invocation.

	* FileSystemInfo.cs: 
	* FileInfo.cs: 
	* File.cs: 
	* Directory.cs: MonoIO methods now have an error parameter

2002-10-31  Gonzalo Paniagua Javier <[email protected]>

	* TextReader.cs: implemented ReadBlock ().

2002-10-30  Miguel de Icaza  <[email protected]>

	* StreamWriter.cs: Ditto for Null stream.

	* BinaryReader.cs: Use Unmarked here too.

	* BinaryWriter.cs: Use the UTF8Unmarker encoding by default, this
	is what .NET does.

2002-10-23  Dick Porter  <[email protected]>

	* FileStream.cs: Implemented CanSeek, and used it around all the
	calls to MonoIO.Seek.  Fixed buffering in Read() so that it
	doesn't block forever on short reads.

	* MonoFileType.cs: New enum for GetFileType
	
	* MonoIO.cs: Added GetFileType

2002-10-21  Gonzalo Paniagua Javier <[email protected]>

	* StreamReader.cs: ReadLine now treats a \r not followed by a \n as a
	\n (this is what MS does).

2002-10-18  Dick Porter  <[email protected]>

	* FileStream.cs: SeekOrigin.End still calculates the offset from
	the end of the file with positive values extending the length.
	Fixes bug 32471.

2002-10-06  Gonzalo Paniagua Javier <[email protected]>

	* Path.cs: some cleanup. Thanks to Martin Aliger.

2002-10-03  Gonzalo Paniagua Javier <[email protected]>

	* FileStream.cs: Do not call FSync on the file.

2002-09-16  Miguel de Icaza  <[email protected]>

	* TextWriter.cs (Null): The Null field should be an instance of a
	TextWriter class that does nothing, so it is an instance of the
	NullTextWriter class.

2002-09-16  Nick Drochak  <[email protected]>

	* MemoryStream.cs (Close): Don't throw an exception if the stream
	is already closed.

2002-09-15  Miguel de Icaza  <[email protected]>

	* FileStream.cs (Dispose): Call FlushBuffer(), and not Flush, as
	Flush calls fsync().  

	The API docs show no explicit mention that Flush() should even do
	an fsync, I am thinking that we should drop that from the
	runtime. 

2002-09-09  Miguel de Icaza  <[email protected]>

	* StreamWriter.cs: When no encoding is provided, create an
	encoding without markers, this is what MS does.

2002-09-06  Miguel de Icaza  <[email protected]>

	* StreamReader.cs: Implement detection of byte marks and skipping
	of byte marks at the beginning of the stream.

	(ReadToEnd): Use buffered read instead of char-by-char
	processing. 

	Correct the default arguments for creating the StreamReader.

2002-08-29  Gonzalo Paniagua Javier <[email protected]>

	that we own the filename.

2002-08-23  Gonzalo Paniagua Javier <[email protected]>

	* FileLoadException.cs: implemented ToString.

	paths contains a colon, as this is a valid part of an identifier
	on Unix.

	Everywhere: The String.Empty return from GetDirectoryName means
	that there is no directory information about the path.

2002-08-20  Gonzalo Paniagua Javier <[email protected]>

	* FileNotFoundException.cs: use Message and InnerException from base
	class. Changed Message and ToString ().

2002-08-19  Dick Porter  <[email protected]>

	* StringWriter.cs: Return UnicodeEncoding for Encoding property.

2002-08-03  Jason Diamond  <[email protected]>

	* StreamWriter.cs: Use GetByteCount() to get exact length instead
	of GetMaxByteCount when converting chars to bytes.

2002-07-31  Duncan Mak  <[email protected]>

	* StreamReader.cs: 
	(Dispose): Added and implmented.

	* StreamWriter.cs:

	end of line detection code instead.

2002-07-02  Gonzalo Paniagua Javier <[email protected]>

	* StreamReader.cs:
	(Peek): no need to have seek capabilitites.

	to ensure the buffer is flushed.

2002-05-15  Nick Drochak  <[email protected]>

	* Path.cs (GetDirectoryName): Return String.Empty if there is no
	directory

	* StreamWriter.cs: Add some parameter checking on file names.

2002-05-14 Nick Drochak  <[email protected]>

	use new internal class since null cannot be passed to constructor 
	anymore. Also, fix a coule of small bugs.

2002-05-03  Nick Drochak  <[email protected]>

	* MemoryStream.cs: Refrain from allocating array until the space is
	really needed. This fixes a bug in the Length property when the

2002-05-01  Duncan Mak  <[email protected]>

	* DirectoryNotFoundException.cs (constructor): Added missing
	serialization constructor.

2002-04-30  Duncan Mak  <[email protected]>

	* FileLoadException.cs (constructors): Added missing (string,
	string) ctor, as well as (string, string, Exception) ctor.

	(Message): Added more info to the error message

	(ToString): Added. We'll need to add the StackTrace stuff when
	that works.

	* FileShare.cs: Add a missing field, Inheritable.
	
	* TextReader.cs: Renamed Synchronised method to Synchronized.

	* TextWriter.cs: Renamed Synchronised method to Synchronized.
	Renamed protected member coreNewLine to CoreNewLine.

2002-04-30  Sergey Chaban  <[email protected]>

2002-03-19  Martin Baulig  <[email protected]>

	* StreamWriter.cs (StreamWriter (string)): The default is to override
	the file, not to append to it.
	(StreamWriter (string path, bool append)): When appending, seek to the
	end of the file, otherwise truncate the file to zero length.
	(Dispose (bool)): Close the internalStream.
	(Flush): Flush the interalStream.
	(Write (char[], int, int)): Flush the internalStream in auto-flush-mode.

2002/03/15 Nick Drochak <[email protected]>

	* DirectoryInfo.cs: Fixed the overloaded GetDirectories and GetFiles.
	This code seemed to be copied from somewhere, and it was close,
	but didn't match the docs.  This was the last bit needed to get
	NAnt to compile with our class libs.

2002-03-12  Duncan Mak  <[email protected]>

	* EndOfStreamException.cs:
	* FileLoadException.cs:

	* System.IO.MemoryStream.cs: Added.  Had quite a few cases of
	"LAMESPEC", but the tests work against the MS implementation so
	the major functions are right (ie. Read/Write/Seek).  Some more
	tests required for the various constructors and exceptions.

2001-07-16  Marcin Szczepanski <[email protected]>

	* StringReader.cs, StringWriter.cs, TextReader.cs, TextWriter.cs:
	New class implemenations.
