10 Indy10 1.9 5/4/2005 7:06:24 PM J. Peter Mugaas Attempt to
fix another junked part of the file.
9 Indy10 1.8 5/4/2005 7:02:50 PM J. Peter Mugaas Attempt to
fix a junked file.
8 Indy10 1.7 5/4/2005 6:31:08 PM J. Peter Mugaas These
should now work. I moved a TextWrapping function out of TIdHeaderList
and into IdGlobalProtocols so the FTP List output object can use it and
so we can rework the routine slightly to use StringBuilder in DotNET.
7 Indy10 1.6 4/28/2005 11:02:30 PM J. Peter Mugaas Removed
StrToInt64Def symbol. We now use Sys.StrToInt64 instead.
6 Indy10 1.5 4/28/2005 10:23:14 PM J. Peter Mugaas Should now
work with new API change in CharInSet.
5 Indy10 1.4 4/20/2005 10:44:24 PM Ben Taylor IdSys
changes
4 Indy10 1.3 4/20/2005 12:43:48 AM J. Peter Mugaas Removed
SysUtils from most units and added it to IdGlobalProtocols (works best
that way).
3 Indy10 1.2 4/19/2005 5:19:11 PM J. Peter Mugaas Removed
SysUtils and fixed EIdException reference.
2 Indy10 1.1 4/19/2005 10:15:26 AM J. Peter Mugaas Updates

Rev 1.16 9/5/2004 2:55:52 AM JPMugaas
Fixed a range check error in

Rev 1.10 09/06/2004 10:03:00 CCostelloe
Kylix 3 patch
Rev 1.9 02/05/2004 13:20:50 CCostelloe
Added RemoveHeaderEntry for use by IdMessage and IdMessageParts (typically
removing old boundary)
Rev 1.8 2/22/2004 12:09:38 AM JPMugaas
Fixes for IMAP4Server compile failure in DotNET. This also fixes a potential
problem where file handles can be leaked in the server needlessly.
Rev 1.7 2/19/2004 11:53:00 PM JPMugaas
Moved some functions out of CoderQuotedPrintable for reuse.
Rev 1.6 2/19/2004 11:40:28 PM JPMugaas
Character to hex translation routine added for QP and some
internationalization work.
Rev 1.5 2/19/2004 3:22:40 PM JPMugaas
ABNFToText and related functions added for some RFC 2234. This is somee
groundwork for RFC 2640 - Internationalization of the File Transfer Protocol.
Rev 1.4 2/16/2004 1:53:34 PM JPMugaas
Moved some routines to the system package.
Rev 1.3 2/11/2004 5:17:50 AM JPMugaas
Bit flip functionality was removed because is problematic on some
architectures. They were used in place of the standard network byte order
conversion routines. On an Intel chip, flip works the same as those but in
architectures where network order is the same as host order, some functions
will fail and you may get strange results. The network byte order conversion
functions provide transparancy amoung architectures.
Rev 1.2 2/9/2004 11:27:48 AM JPMugaas
Some functions weren't working as expected. Renamed them to describe them
better.
Rev 1.1 2/7/2004 7:18:38 PM JPMugaas
Moved some functions out of IdDNSCommon so we can use them elsewhere.
Rev 1.0 2004.02.03 7:46:04 PM czhower
New names
Rev 1.43 1/31/2004 3:31:58 PM JPMugaas
Removed some File System stuff for new package.
Rev 1.42 1/31/2004 1:00:26 AM JPMugaas
FileDateByName was changed to LocalFileDateByName as that uses the Local Time
Zone.
Added BMTDateByName for some GMT-based stuff.
We now use the IdFileSystem*.pas units instead of SysUtils for directory
functions. This should remove a dependancy on platform specific things in
DotNET.
Rev 1.41 1/29/2004 6:22:22 AM JPMugaas
IndyComputerName will now use Environment.MachineName in DotNET. This should
fix the ESMTP bug where IndyComputerName would return nothing causing an EHLO
and HELO command to fail in TIdSMTP under DotNET.
Rev 1.40 2004.01.22 5:58:56 PM czhower
IdCriticalSection

Fix to Compile
Rev 1.36 11/29/2003 12:19:50 AM JPMugaas
CompareDateTime added for more accurate DateTime comparisons. Sometimes
comparing two floating point values for equality will fail because they are
of different percision and some fractions such as 1/3 and pi (7/22) can never
be calculated 100% accurately.
Rev 1.35 25/11/2003 12:24:20 PM SGrobety
various IdStream fixes with ReadLn/D6
Rev 1.34 10/16/2003 11:18:10 PM DSiders

Update ROL and ROR for DotNet
Rev 1.29 10/5/2003 11:43:32 PM GGrieve
Add IsLeadChar
Rev 1.28 10/5/2003 5:00:10 PM GGrieve
GetComputerName (once was IndyGetHostName)

GetClockValue added for unique clock values.
Rev 1.15 5/8/2003 08:43:14 PM JPMugaas
Function for finding an integer's position in an array of integers. This is
required by some SASL code.
Rev 1.14 4/21/2003 7:52:58 PM BGooijen
other nt version detection, removed non-existing windows versions
Rev 1.13 4/18/2003 09:28:24 PM JPMugaas
Changed Win32 Operating System detection so it can distinguish between
workstation OS NT versions and server versions. I also added specific
detection for Windows NT 4.0 with a Service Pack below 6 (requested by Bas).
Rev 1.12 2003.04.16 10:06:22 PM czhower
Moved DebugOutput to IdCoreGlobal
Rev 1.11 4/10/2003 02:54:32 PM JPMugaas
Improvement for FTP STOU command. Unique filename now uses
IdGlobal.GetUniqueFileName instead of Rand. I also fixed GetUniqueFileName
so that it can accept an empty path specification.
Rev 1.10 4/5/2003 10:39:06 PM BGooijen
LAM,LPM were not initialized
Rev 1.9 4/5/2003 04:12:00 AM JPMugaas

FileDateByName now works on directories.
Rev 1.5 2/14/2003 11:50:58 AM JPMugaas
Removed a function for giving an OS identifier in the FTP server because we
no longer use that function.
Rev 1.4 1/27/2003 12:30:22 AM JPMugaas
Forgot to add a space after one OS type. That makes the job a little easier
for the FTP Server SYST command handler.
Rev 1.3 1/26/2003 11:56:30 PM JPMugaas
Added function for returning an OS descriptor for combining with a FTP Server
SysDescription for the SYST command reply. This can also optionally return
the true system identifier.
Rev 1.2 1/9/2003 05:39:08 PM JPMugaas
Added workaround for if the date is missing a space after a comma.
Rev 1.1 12/29/2002 2:13:14 PM JPMugaas

These are for handling binary values that are in Network Byte order. They call
ntohs, ntols, htons, and htons which are required by SNTP and FSP
(probably some other protocols). They aren't aren't in IdGlobals because that
doesn't refer to IdStack so you can't use GStack there.

// RLebeau: According to RFC 2822 Section 4.3:
//
// In the obsolete time zone, "UT" and "GMT" are indications of
// "Universal Time" and "Greenwich Mean Time" respectively and are both
// semantically identical to "+0000".
//
// The remaining three character zones are the US time zones. The first
// letter, "E", "C", "M", or "P" stands for "Eastern", "Central",
// "Mountain" and "Pacific". The second letter is either "S" for
// "Standard" time, or "D" for "Daylight" (or summer) time. Their
// interpretations are as follows:
//
// EDT is semantically equivalent to -0400
// EST is semantically equivalent to -0500
// CDT is semantically equivalent to -0500
// CST is semantically equivalent to -0600
// MDT is semantically equivalent to -0600
// MST is semantically equivalent to -0700
// PDT is semantically equivalent to -0700
// PST is semantically equivalent to -0800
//
// The 1 character military time zones were defined in a non-standard
// way in [RFC822] and are therefore unpredictable in their meaning.
// The original definitions of the military zones "A" through "I" are
// equivalent to "+0100" through "+0900" respectively; "K", "L", and "M"
// are equivalent to "+1000", "+1100", and "+1200" respectively; "N"
// through "Y" are equivalent to "-0100" through "-1200" respectively;
// and "Z" is equivalent to "+0000". However, because of the error in
// [RFC822], they SHOULD all be considered equivalent to "-0000" unless
// there is out-of-band information confirming their meaning.
//
// Other multi-character (usually between 3 and 5) alphabetic time zones
// have been used in Internet messages. Any such time zone whose
// meaning is not known SHOULD be considered equivalent to "-0000"
// unless there is out-of-band information confirming their meaning.
// RLebeau: according to http://en.wikipedia.org/wiki/Central_European_Time:
//
// Central European Time (CET) is one of the names of the time zone that is
// 1 hour ahead of Coordinated Universal Time. It is used in most European
// and some North African countries.
//
// Its time offset is normally UTC+1. During daylight saving time, Central
// European Summer Time (CEST) is used instead (UTC+2). The current time
// offset is UTC+1.

You should not use a text MIME type definition unless you are
extremely certain that the file will NOT be a binary. Some browsers
will display the text instead of saving to disk and it looks ugly
if a web-browser shows all of the 8bit charactors.
