3 * StreamReader.cs: when a LF ends a decoded buffer and is not followed
4 by a CR in the next decoded buffer, we didn't flush the string.
7 2009-01-08 Christian Prochnow <cproch@seculogix.de>
9 * DriveInfo.cs: Added GetDiskFreeSpaceInternal
10 to query drive size and free space.

13 2008-12-20 Miguel de Icaza <miguel@novell.com>
15 * FileStream.cs: Found while debugging webcompare, we should add
16 Obsoletes to the FileStream constructors that take IntPtrs.
18 2008-11-27 Sebastien Pouliot <sebastien@ximian.com>
20 * FileInfo.cs: Change ToString (in 2.1) not to return the full path
21 of the filename (since it's not SecurityCritical).
23 2008-11-09 William Holmes <billholmes54@gmail.com>
25 * TextReader.cs : Adding the NullTextReader as a private class to
26 the TestReader class for the Null field of the TestReader.

44 2008-08-22 Sebastien Pouliot <sebastien@ximian.com>
46 * FileStream.cs, MonoIO.cs: For Silverlight 2.0 (NET_2_1) we always
47 throw IsolatedStorageException instead of FileNotFoundException and
48 DirectoryNotFoundException.
50 2008-08-21 Sebastien Pouliot <sebastien@ximian.com>
52 * FileStream.cs: Adjust exception being thrown for Silverlight 2.0.
53 * FileSystemInfo.cs: In Silverlight 2 this type does not inherit from
54 MarshalByRefObject nor does it implement ISerializable.
55 * Stream.cs: In Silverlight 2 this type does not inherit from
57 * TextReader.cs: In Silverlight 2 this type does not inherit from
59 * TextWriter.cs: In Silverlight 2 this type does not inherit from
61 * UnmanagedMemoryStream.cs: For Silverlight 2 add CLSCompliant(false)
62 to the PositionPointer property.
64 2008-08-15 Gert Driesen <drieseng@users.sourceforge.net>
66 * StreamWriter.cs: Change argument check for buffersize to require
67 positive number. Removed duplicate disposed check for AutoFlush.
68 Removed unnecessary initialization of bools.
70 2008-08-15 Gert Driesen <drieseng@users.sourceforge.net>
72 * StreamWriter.cs: Removed duplicate argument checks from .ctor taking
73 path, as these checks are already done in FileStream .ctor. Removed
74 parameter name from ArgumentException to match MS.
76 2008-07-28 Marek Safar <marek.safar@gmail.com>
78 * File.cs: Delay DateTime .cctor invocation.

107 2008-06-21 Gert Driesen <drieseng@users.sourceforge.net>
109 * Path.cs: Fixed exception arguments to match MS. Removed obsolete
110 LAMESPEC comment. In GetPathRoot, throw ArgumentException if path
111 is whitespace-only. Throw ArgumentException in HasExtension, if path
112 contains invalid path characters.
114 2008-05-29 Robert Jordan <robertj@gmx.net>
116 * Path.cs (InsecureGetFullPath): Call CanonicalizePath for
118 * Path.cs (GetServerAndShare): New helper method.

123 2008-05-14 Andreas Nahr <ClassDevelopment@A-SoftTech.com>
125 * DriveInfo.cs: Fix compiler warning
127 2008-05-07 Sebastien Pouliot <sebastien@ximian.com>
129 * CheckArgument.cs: Removed. Lots of unused code. The two methods
130 used are now inlined into Path.cs
131 * CheckPermission.cs: Removed. Lots of unused code.
132 * Path.cs: Inlined two checks.
133 [Found using Gendarme]
135 2008-04-18 Sebastien Pouliot <sebastien@ximian.com>
137 * Path.cs: Change PathSeparatorChars from private to internal since
138 it's needed for IsolatedStorage.
140 2008-04-17 Gert Driesen <drieseng@users.sourceforge.net>
142 * DirectoryInfo.cs: Added new internal ctor, which takes a bool that
143 indicates whether the original path should only container the last
144 part of the directory. Moved logic for determining the Name and
145 Parent to Initialize method, to allow it to be re-used on
146 deserialization. Renamed argument names to fix corcompare issues.
147 Added missing argument checks.
148 * Directory.cs (CreateDirectoriesInternal): Use internal ctor for
149 DirectoryInfo to ensure OriginalPath only contains last part of
151 * File.cs: Removed redundant checks from Create. On 2.0 profile, pass
152 FileOptions to FileStream. Removed redundant directory check from
153 Delete and modified exceptions to more closely match MS.
154 * FileInfo.cs: Added argument check to ctor to match MS. Added missing
155 deserialization ctor. Modified argument checks in MoveTo, and removed
156 redundant checks. Added missing argument checks in CopyTo. Code

165 2008-04-16 Gert Driesen <drieseng@users.sourceforge.net>
167 * File.cs: Changed argument names and thrown exception to better match
168 .NET. Use String.Length instead of comparison with empty string.
169 * DirectoryInfo.cs: Added missing deserialization ctor.
171 2008-04-04 Dick Porter <dick@ximian.com>
173 * File.cs: Pretty up the file share exception with the path name.
175 2008-03-28 Sebastien Pouliot <sebastien@ximian.com>
177 * Directory.cs: Exception differs when deleting a directory if it
178 does not exists or if a file of the same name exists. Also don't
179 include path in exception if Delete fails.
181 2008-03-20 Marek Safar <marek.safar@gmail.com>
183 * Path.cs (Combine): Call ToString to optimize concatenation.
185 2008-03-02 Gert Driesen <drieseng@users.sourceforge.net>
187 * DriveInfo.cs: Removed debug code.
189 2008-02-15 Miguel de Icaza <miguel@novell.com>
191 * UnmanagedMemoryStream.cs: Implement few missing pieces.
193 2008-02-10 Zoltan Varga <vargaz@gmail.com>
195 * UnexceptionalStreamReader.cs (Read): Optimize this to avoid making a number of
196 calls + creation of a string for each character read.

210 unsafe icalls. Fixes #350860.
212 2007-11-21 Atsushi Enomoto <atsushi@ximian.com>
214 * FileStream.cs : Close() does not exist in 2.0 (Stream does).
215 Move GC.SuppressFinalize() to Dispose(true).
217 2007-11-12 Juraj Skripsky <js@hotfeet.ch>
219 * Path.cs (GetRandomFileName): Return filenames containing only
220 characters from the range [a..z0..9] as MS.NET does.
222 2007-11-02 Atsushi Enomoto <atsushi@ximian.com>
224 * StreamReader.cs : Encoding.GetMaxCharCount() does not always return
225 the maximum max char count for Decoder.GetChars() since it might
226 contain pending buffer by flush. Fixed bug #338370.
228 2007-11-01 Miguel de Icaza <miguel@novell.com>
230 * Path.cs (GetDirectoryName): The paths returned from this routine
231 should be canonical, not just a substring. In addition to fixing
232 this, it also fixes #324742.
234 2007-10-26 Atsushi Enomoto <atsushi@ximian.com>
236 * BinaryReader.cs, BinaryWriter.cs : use unsafe encoding that has ""
237 for replacement fallback. Binary serialization regression is fixed.
239 2007-09-06 Atsushi Enomoto <atsushi@ximian.com>
241 * Stream.cs, BufferedStream.cs, MemoryStream.cs: in 2.0 override
242 Dispose(bool) rather than Close().
243 Stream.Dispose() is virtual in 2.0.
245 2007-08-24 Gert Driesen <drieseng@users.sourceforge.net>
247 * BinaryReader.cs: Fixed line endings.
248 * FileStream.cs: Rename name argument to path. Spaces to tabs.
250 2007-08-20 William Holmes <billholmes54@gmail.com>
252 *File.cs: Add implementation for IO.File.Replace methods.
253 *MonoIO.cs: Declared an internal call for ReplaceFile
255 Code is contributed under MIT/X11 license.
257 2007-07-31 Dick Porter <dick@ximian.com>
259 * MonoIO.cs: Fix formatting of 'access denied' exception when the
260 path info isn't known. Fixes bug 82141.
262 2007-07-08 Gert Driesen <drieseng@users.sourceforge.net>
264 * Directory.cs: Renamed Move arguments to match MS. Allow Move to be
265 used to move files, patch by Robert Jordan. Fixes bug #81912. Spaces
268 2007-06-21 Dick Porter <dick@ximian.com>
270 * FileStream.cs: Fix FileShare test, fixing better bug 79250.
272 2007-05-28 Atsushi Enomoto <atsushi@ximian.com>
274 * UnmanagedMemoryStream.cs : added Closed event for sys.Resources use.
275 * IntPtrStream.cs : added internal get_BaseAddress(), for the same.
277 2007-05-25 Gert Driesen <drieseng@users.sourceforge.net>
279 * UnmanagedMemoryStream.cs: In Read and ReadByte, use Marshal.ReadByte
280 to read bytes as this allows us to start reading from the current
281 position. In Read, return 0 when reading beyond the end of the stream
282 and only read bytes until the end of the stream (not capacity).
283 In ReadByte, return -1 when reading beyond the end of the stream.
284 In SetLength: changed argument validation (and reported exceptions) to
285 match MS, removed duplicate access check and changed the current
286 position if length is less than position. In Write: throw
287 NotSupportedException when attempting to write beyond capacity, use
288 Marshal.WriteByte since that allows us to start writing from the
289 current position. Adjust length when position moves beyond length
290 in both Write and WriteByte. Allow position to be moved beyond
291 capacity of stream. Fixed position using Seek (=+ typo). Changed
292 CanRead to ignore current position. Allow Position to be used to move
293 beyond capacity of stream.
295 2007-05-24 Gert Driesen <drieseng@users.sourceforge.net>
297 * UnmanagedMemoryStream.cs: Changed argument names and exceptions
298 (msg, params) to match MS. Verify access argument in ctor.
300 2007-05-23 Atsushi Enomoto <atsushi@ximian.com>
302 * UnmanagedMemoryStream.cs : couple of bugfixes. in Read(), don't
303 return buffer beyond the requested length. Fixed .ctor() for wrong
304 capacity initialization.
306 2007-05-12 Jonathan Chambers <joncham@gmail.com>
308 * FileStream.cs: Implement SafeHandle constructors.
310 2007-05-01 Dick Porter <dick@ximian.com>
313 * Stream.cs: Missed a few 2.0 methods
315 2007-04-30 Dick Porter <dick@ximian.com>
319 * DirectoryNotFoundException.cs:
330 * UnmanagedMemoryStream.cs:
333 * FileLoadException.cs:
340 * EndOfStreamException.cs:
343 * PathTooLongException.cs:
345 * FileNotFoundException.cs: 2.0 profile updates
347 2007-04-21 Alp Toker <alp@atoker.com>
349 * FileStream.cs: Respect request for buffering in all cases.
351 Gonzalo added code in r42667 that disables buffering even when it is
352 requested, in the case that ftype != MonoFileType.Disk. This was
353 killing performance for users who do Console.OpenStandardOutput(1024)
354 but were ending up with a non-buffered FileStream.
356 The new behaviour appears correct but we should watch for any
359 2007-04-05 Dick Porter <dick@ximian.com>
361 * Directory.cs: Pass combined path and pattern to
362 MonoIO.GetFileSystemEntries()
364 2007-04-03 Alp Toker <alp@atoker.com>
366 * UnmanagedMemoryStream.cs: Should not have a public Dispose().
367 This behaviour is already provided by the base class.
369 2007-04-03 Alp Toker <alp@atoker.com>
371 * Stream.cs: CreateWaitHandle() obsolete in 2.0.
373 2007-03-18 Alp Toker <alp@atoker.com>
375 * UnmanagedMemoryStream.cs:
376 * Directory.cs: Exception message typo fixes.
378 2007-03-11 Zoltan Varga <vargaz@gmail.com>
380 * UnmanagedMemoryStream.cs: Fix a warning.
382 2007-03-05 Miguel de Icaza <miguel@novell.com>
384 * Path.cs: Manually call FileStream and pass the new internal
385 FileOptions.1 flag that means "This is a temporary file, use 600
388 * FileOptions.cs: Document the new private enum value.
390 2007-02-22 Dick Porter <dick@ximian.com>
393 * MonoIO.cs: Handle ERROR_CANNOT_MAKE.
395 2007-02-19 Eyal Alaluf <eyala@mainsoft.com>
397 * DirectoryInfo.cs, Directory.cs: Use MonoNotSupported & MonoLimitation
398 attribute to tag that DirectorySecurity is not supported.
400 2007-02-19 Boris Kirzner <borisk@mainsoft.com>
402 * Path.cs: fix order of InvalidPathChars on windows.
404 2007-01-31 Gert Driesen <drieseng@users.sourceforge.net>
406 * StreamReader.cs: Removed checks for non-existing directory or file,
407 since these checks are also performed in FileStream.
409 2007-01-31 Gert Driesen <drieseng@users.sourceforge.net>
411 * FileStream.cs: Always resolve to absolute paths for exceptions, when not
414 2007-01-24 Gonzalo Paniagua Javier <gonzalo.mono@gmail.com>
416 * StreamReader.cs: fix for bug #75526. We return earlier from Read () if
417 the underlying stream might block or end on the next read.
419 2007-01-22 Miguel de Icaza <miguel@novell.com>
421 * DirectoryInfo.cs: Throw a better exception (accorind go the
422 docs, UnauthorizedAccessException is thrown if the underlying
423 platform does not support it and *also* if there are no
424 permissions to access it, which is more convenient than the
425 PlatformNotSupportedException that only states that it needs Win2k
428 2006-12-23 Alp Toker <alp@atoker.com>
430 * Directory.cs: "platfor" typofix
432 2006-12-22 Sebastien Pouliot <sebastien@ximian.com>
434 * File.cs: Add stubs for Encrypt and Decrypt that throws
435 NotSupportedException just like non-NTFS file systems would with MS.
436 Remove nested #if NET_2_0.
437 * FileInfo.cs: Add stubs for Encrypt and Decrypt that throws
438 NotSupportedException just like non-NTFS file systems would with MS.
440 2006-12-22 Atsushi Enomoto <atsushi@ximian.com>
442 * Directory.cs : non NET_2_0 build fix.
444 2006-12-15 Miguel de Icaza <miguel@novell.com>

448 Mon Dec 11 11:40:06 CET 2006 Paolo Molaro <lupus@ximian.com>
450 * FileStream.cs: correct exception message patch from
451 Markus Mauhart <mmauhart@chello.at>.

466 * DirectoryInfo.cs (GetFiles): Implement option with SearchOptions
469 2006-11-13 Dick Porter <dick@ximian.com>
471 * Directory.cs: Don't follow symlinks when deleting directories.
472 Keeps bug 79733 fixed while fixing bug 79887.
474 * MonoIO.cs: ExistsSymlink() added, which checks for
475 FileAttributes.ReparsePoint.
477 2006-11-07 Dick Porter <dick@ximian.com>
479 * Directory.cs: CreateDirectory() should only throw IOException in
480 the 2.0 profile if a file already exists with the same name, not a
483 2006-11-03 Jensen Somers <jensen.somers@gmail.com>
485 * Directory.cs: CreateDirectory() should throw IOException if a
486 file or directory with the same name already exists, in the 2.0
487 profile. Fixes bug 79806.

504 * FileInfo.cs: eol-style.
506 2006-09-19 Gert Driesen <drieseng@users.sourceforge.net>
508 * FileNotFoundException.cs: Changed message for default ctor to match
509 MS. Use internal message field of Exception to check whether Message
510 is null. On 2.0 profile, use file/assembly load failure message when
511 no message is set and a filename was specified. On 1.0 profile,
512 always use file/assembly load failure message when no message is set
513 (regardless of whether a filename was specified or not). Made some
514 cosmetic changes to ToString to have it match MS.
516 2006-09-02 Zoltan Varga <vargaz@gmail.com>
518 * BinaryReader.cs (Read): Avoid allocating memory when reading a char.
520 2006-08-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>

523 stream returns -1 on Read.
525 2006-08-30 Lluis Sanchez Gual <lluis@novell.com>

529 2006-08-21 Sebastien Pouliot <sebastien@ximian.com>
531 * Path.cs: Added internal method IsPathSubsetOf required to implement
532 correctly FileIOPermission (better located here).
534 2006-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>
536 * File.cs: (Delete) avoid creating the exception object for the 'file
539 2006-07-24 Miguel de Icaza <miguel@novell.com>
541 * FileShare.cs: Add Delete in 2.0
543 2006-07-06 Dick Porter <dick@ximian.com>
545 * Directory.cs: When creating a directory treat ERROR_FILE_EXISTS
546 (ie a file already exists with that name) the same as
547 ERROR_ALREADY_EXISTS (ie a directory already exists with that
548 name.) Keeps bug 50753 fixed when I fix the io-layer
549 CreateDirectory() behaviour.
551 2006-06-21 Atsushi Enomoto <atsushi@ximian.com>
553 * Directory.cs : implemented GetFiles() and GetDirectories() which

570 * BinaryReader.cs: use BlockCopyInternal.
572 2006-05-01 Daniel Drake <dsd@gentoo.org>
574 * Directory.cs: Return false (as documented) on ERROR_ACCESS_DENIED in
575 Exists() rather than throwing an exception. Bug #78239.
577 2006-04-29 Atsushi Enomoto <atsushi@ximian.com>
579 * UnexceptionalStreamReader.cs (Read): Fix for #78218, where we
580 consumed characters from the input even when the count was not set
581 to zero, causing some characters to be missing in some
584 2006-04-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
586 * Directory.cs: make sure the parent directory is not an empty string
587 when a file name with no path is provided. Fixes bug #78209. Patch by
590 2006-04-28 Atsushi Enomoto <atsushi@ximian.com>
592 * StreamReader.cs : implemented EndOfStream property.
593 * File.cs : implemented AppendAllText(), WriteAllLines(),

599 part of a UNC. Fixes #78147.
602 2006-04-26 Miguel de Icaza <miguel@novell.com>
604 * FileStream.cs: Implement the FileOptions usage by passing all
605 the information to the C layer. Remove the "isAsync" argument for
606 MonoIO.Open, and instead pass it on the FileOptions.
608 * FileOptions.cs: Make it build when including WriteThrough
610 * MonoIO.cs: Update MonoIO.Open signature to drop the async
611 argument and take FileOptions instead.
613 2006-04-21 Zoltan Varga <vargaz@gmail.com>
615 * FileStream.cs: Add new net 2.0 ctor.
617 * FileOptions.cs: New file.
619 2006-03-21 Miguel de Icaza <miguel@novell.com>

628 2006-03-07 Carlos Alberto Cortez <calberto.cortez@gmail.com>
630 * Stream.cs: Add 2.0 members to Stream.cs (CanTimeout,
631 ReadTimeout and WriteTimeout).
633 2006-02-27 Gert Driesen <drieseng@users.sourceforge.net>
635 * File.cs: In 2.0 profile, File.Get****Time(Utc) should not throw
636 IOException if specified path does not exist. Fixes bug #77641.
638 2006-02-26 Gert Driesen <drieseng@users.sourceforge.net>

777 * BinaryReader.cs: The patch below had a nasty little bug with
778 long strings that had non-ascii chars in it, because it was
779 looking at the char count, not the byte count.
781 2005-09-11 Ben Maurer <bmaurer@ximian.com>
783 * BinaryReader.cs: An optimization for ReadString that had been

965 * DirectoryInfo.cs (CreateSubDirectory): Check the input here.

974 2004-11-01 Ben Maurer <bmaurer@ximian.com>
976 * MonoIOError.cs: All of these fields just take up room in corlib,

978 runtime about them. Since most are not used, am commenting them
981 2004-09-19 Dick Porter <dick@ximian.com>
983 * UnexceptionalStreamWriter.cs:
984 * UnexceptionalStreamReader.cs: Wrappers around StreamWriter and

1008 2004-09-05 Ben Maurer <bmaurer@users.sourceforge.net>
1010 * Path.cs (Combine): Array.IndexOf is slow (because of the
1011 special cases it must handle). So, rather than doing IndexOf
1012 just check each type of seperator.
1014 2004-09-05 Ben Maurer <bmaurer@users.sourceforge.net>
1016 * StringReader.cs (StreamReader): remove sourceChars and disposed
1018 (Read): Copy directly from the string, rather than a char []
1019 (Dispose, CheckObjectDisposedException): the flag for being
1020 disposed is now source == null.

1043 Don't blow away the SetFileTime() error before the caller gets to
1044 see it. Part of the bug fix to 60970.
1046 2004-07-05 Dick Porter <dick@ximian.com>
1048 * CheckPermission.cs:

1077 * FileStream.cs : Check buffer size before creating file.
1078 * StreamReader.cs : Check encoding!=null before creating file.
1080 MonoIO.cs : Convert DateTime to FileTime after checking
1081 file IO sharing violation (it just fixes the type of exception).
1083 2004-06-15 Gert Driesen <drieseng@users.sourceforge.net>

1131 * FileStream.cs (SetLength): The other exceptions have precendence
1132 over ObjectDisposedException, which is not one of the exceptions
1133 listed in the documentation). Also, instead of throwing an
1134 ObjectDisposedException, throw an IOException.

1402 This fixes bug #53026. Miguel de Icaza reviewed/approved this
1405 2004-01-14 Zoltan Varga <vargaz@freemail.hu>
1407 * FileStream.cs (.ctor): Avoid allocating a large buffer when reading
1410 2004-01-10 Atsushi Enomoto <atsushi@ximian.com>

1878 data, not the whole buffer. (note: this makes XmlDocument.Load work
1879 again with documents that have a <?xml without the 'encoding'
1880 attribute, which makes gtk-sharp generator work again).
1882 2003-02-25 Nick Drochak <ndrochak@gol.com>
1884 * File.cs (GetCreationTime): Throw proper execption when path is not
1887 Tue Feb 25 11:55:35 CET 2003 Paolo Molaro <lupus@ximian.com>

1900 back over old data (undocumented ms behaviour, throws an exception
1901 if you try). Fixes bug 35975.
1903 2003-02-17 Dick Porter <dick@ximian.com>
1905 * FileStream.cs: Don't close the handle if the stream doesn't own

1920 * MemoryStream.cs: create the buffer of the specified capacity.
1922 2003-01-31 Patrik Torstensson
1924 * MemoryStream.cs: use BlockCopyInternal instead of Array.Copy, this is

1927 2003-01-29 Zoltan Varga <vargaz@freemail.hu>
1929 * Directory.cs (GetFileSystemEntries): moved error handling to the
1930 correct instance of GetFileSystemEntries so all callers can enjoy it.

1977 * Directory.cs: CreateDirectory works now with Absolute paths
1978 too, not only with relative ones.
1980 2002-12-07 Peter Williams <peterw@ximian.com>
1982 * Directory.cs: Don't use the uninitialized pathsumm here.

1985 2002-12-07 Eduardo Garcia Cebollero <kiwnix@yahoo.es>
1987 * Directory.cs: Now the creation of a new directory works recursively
1988 it will make parents as needed.

2008 2002-10-31 Dick Porter <dick@ximian.com>
2010 * FileStream.cs: Fix buffering properly this time. Also kludge
2011 around broken pipe errors, treating them as EOF instead of
2012 throwing an IO exception.
2014 * MonoIO.cs: Return the error status in a parameter, as the
2015 GetLastError() value has long since been blown away if we try and
2016 look it up in a subsequent internal call invocation.

2021 * Directory.cs: MonoIO methods now have an error parameter
2023 2002-10-31 Gonzalo Paniagua Javier <gonzalo@ximian.com>

2036 2002-10-23 Dick Porter <dick@ximian.com>
2038 * FileStream.cs: Implemented CanSeek, and used it around all the
2039 calls to MonoIO.Seek. Fixed buffering in Read() so that it
2040 doesn't block forever on short reads.

2044 * MonoIO.cs: Added GetFileType
2046 2002-10-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2048 * StreamReader.cs: ReadLine now treats a \r not followed by a \n as a

2051 2002-10-18 Dick Porter <dick@ximian.com>
2053 * FileStream.cs: SeekOrigin.End still calculates the offset from
2054 the end of the file with positive values extending the length.

2078 2002-09-16 Miguel de Icaza <miguel@ximian.com>
2080 * TextWriter.cs (Null): The Null field should be an instance of a
2081 TextWriter class that does nothing, so it is an instance of the
2082 NullTextWriter class.
2084 2002-09-16 Nick Drochak <ndrochak@gol.com>
2086 * MemoryStream.cs (Close): Don't throw an exception if the stream
2089 2002-09-15 Miguel de Icaza <miguel@ximian.com>
2091 * FileStream.cs (Dispose): Call FlushBuffer(), and not Flush, as
2092 Flush calls fsync().
2094 The API docs show no explicit mention that Flush() should even do
2095 an fsync, I am thinking that we should drop that from the
2098 2002-09-09 Miguel de Icaza <miguel@ximian.com>
2100 * StreamWriter.cs: When no encoding is provided, create an
2101 encoding without markers, this is what MS does.
2103 2002-09-06 Miguel de Icaza <miguel@ximian.com>

2134 2002-08-24 Miguel de Icaza <miguel@ximian.com>
2136 * StreamReader.cs: Removed TODOs, as the code seems to be
2139 * Path.cs (GetTempFileName): Make this routine atomic by not
2140 testing and then creating, but using the create call to ensure
2141 that we own the filename.
2143 2002-08-23 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2145 * FileLoadException.cs: implemented ToString.

2156 * Path.cs (GetDirectoryName): Fix for filenames with size = 1
2158 * File.cs: Removed all references that threw exceptions when the
2159 paths contains a colon, as this is a valid part of an identifier
2162 Everywhere: The String.Empty return from GetDirectoryName means
2163 that there is no directory information about the path.
2165 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2167 * FileNotFoundException.cs: use Message and InnerException from base
2168 class. Changed Message and ToString ().

2263 * StreamWriter.cs: added ability to write null value
2265 2002-05-19 Lawrence Pit <loz@cable.a2000.nl>
2267 * Stream.cs: NullStream.ReadByte now returns -1 instead of 0 to

2310 2002-05-09 Nick Drochak <ndrochak@gol.com>
2312 * File.cs (Delete): Do not throw an exception if the file does not
2315 2002-05-08 Mike Gray <mikeg@mikegray.org>

2343 anymore. Also, fix a coule of small bugs.
2345 2002-05-03 Nick Drochak <ndrochak@gol.com>
2347 * MemoryStream.cs: Refrain from allocating array until the space is
2348 really needed. This fixes a bug in the Length property when the

2376 Handle end of stream properly. Methods to read native types
2377 (ReadInt* etc.) are little-endian (see Compact Framework docs).
2379 * BinaryWriter.cs: Store data in little-endian format.
2380 Use internal buffer for conversions.
2382 2002-03-31 Dick Porter <dick@ximian.com>

2427 2002-03-19 Martin Baulig <martin@gnome.org>
2429 * StreamWriter.cs (StreamWriter (string)): The default is to override
2430 the file, not to append to it.
2431 (StreamWriter (string path, bool append)): When appending, seek to the
2432 end of the file, otherwise truncate the file to zero length.
2433 (Dispose (bool)): Close the internalStream.

2441 2002-02-28 Miguel de Icaza <miguel@ximian.com>
2443 * Stream.cs (NullStream): Do not track position, this beast does
2444 nothing in practice.
2446 2002-03-15 Dan Lewis <dihlewis@yahoo.co.uk>
2448 * SearchPattern.cs: New class. Glob matching code for Directory.
2449 * Directory.cs: Changed to use SearchPattern instead of mono_glob_*()
2451 2002/03/15 Nick Drochak <ndrochak@gol.com>
2453 * DirectoryInfo.cs: Fixed the overloaded GetDirectories and GetFiles.
2454 This code seemed to be copied from somewhere, and it was close,
2455 but didn't match the docs. This was the last bit needed to get
2456 NAnt to compile with our class libs.
2458 2002-03-12 Duncan Mak <duncan@ximian.com>

2468 2002-03-07 Nick Drochak <ndrochak@gol.com>
2470 * FileMode.cs: Docs don't say this should be explicitly derived from
