	Carlos Alberto Cesario <[email protected]>.

2004-07-05  Dick Porter  <[email protected]>

	* File.cs: File.Move() should check that the destination doesn't

	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]>

	\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]>

	* StreamReader.cs: give more information when wrong parameters passed.

2002-09-21  Miguel de Icaza  <[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.

	* TextWriter.cs: IDisposable fixes.

2002-08-24  Miguel de Icaza  <[email protected]>

	* StreamReader.cs: Removed TODOs, as the code seems to be
	complete. 

	* Path.cs (GetTempFileName): Make this routine atomic by not
	testing and then creating, but using the create call to ensure
	that we own the filename.

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

	* FileLoadException.cs: implemented ToString.

	* Path.cs (GetDirectoryName): Fix for filenames with size = 1

	* File.cs: Removed all references that threw exceptions when the
	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]>

	chars

2002-08-18  Dick Porter  <[email protected]>

	* BinaryReader.cs: Fixed buffering

2002-08-09  Nick Drochak  <[email protected]>

	* BinaryReader.cs: added virtual to Dispose(bool).

2002-08-03  Jason Diamond  <[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:

2002-07-17  Gonzalo Paniagua Javier <[email protected]>

	* Path.cs: removed unneeded line from GetExtension.

2002-07-12  Gonzalo Paniagua Javier <[email protected]>

	* FileStream.cs:
	(.ctor): call MonoIO.GetException with the file name.

2002-07-02  Mike Kestner  <[email protected]>

	* StreamReader.cs: Guard against ^\n lines as pointed out by Gonzalo.

2002-07-02  Mike Kestner  <[email protected]>

	* StreamReader.cs: Revert the last Peek change and fix the ReadLine
	end of line detection code instead.

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

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

2002-06-17  Dietmar Maurer  <[email protected]>

	* File.cs (Delete): only call Directory.Exists() if DirName != ""

2002-06-12  Gonzalo Paniagua Javier <[email protected]>

	before performing the search.

2002-06-12  Nick Drochak  <[email protected]>

	* StringReader.cs (ReadLine): Return null when we get to end of the
	string.

	pattern as recommended by the MS docs.  Must call Close() now
	to ensure the buffer is flushed.

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

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

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

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

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

	exist.

2002-05-08  Mike Gray     <[email protected]>

	exceptions where appropriate.

Tue May 7 11:47:46 CEST 2002 Paolo Molaro <[email protected]>

	* FileInfo.cs (Create): Implement missing method.

2002-05-07  Mike Gray     <[email protected]>

	to compare against "" instead of null twice.

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

	* StreamReader.cs: Throw exceptions where needed. Changed Null field to
	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
	constructor without the byte array is used.

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]>

	Handle end of stream properly. Methods to read native types
	(ReadInt* etc.) are little-endian (see Compact Framework docs).

2002-03-31  Dick Porter  <[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.

2002-03-19  Dan Lewis <[email protected]>

2002-02-28  Miguel de Icaza  <[email protected]>

	* Directory.cs: Changed to use SearchPattern instead of mono_glob_*()

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:
	* FileNotFoundException.cs:

2002-03-02  Jason Diamond  <[email protected]>

	* StringReader.cs: Fixed off-by-one error in Peek() and Read().

2002-02-12  Nick Drochak  <[email protected]>

Thu Jan 10 12:06:46 MST 2002 Matt Kimball <[email protected]>

	* BufferedStream.cs: Initial implemenation.  The synchronous

	asynchronous methods in a bit.
	
Wed Jan  9 16:04:39 MST 2002 Matt Kimball <[email protected]>

	* BinaryWriter.cs: Initial implementation.  And it's all there.

2001-07-19  Marcin Szczepanski <[email protected]>

	* 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.
