Avoid doing seeks on the physical file reprensation when it is not absolutely necessary
(i.e. it is not need if we are going to pick the data from our cache).
Introduce a SetOffset to change fOffset (i.e. the logical position in the file) without doing a lseek.
Introduce ReadBuffer(char * buf, Long64_t pos, Int_t len) to avoid the lseek when the data is in the cache.

From Gerri and me:
- don't use TUrl to strip off "file:" protocol string from file names
as this was also striping off everything after # and ? tokens, making
it impossible to e.g. stat local file names like .#bla#.
- make copy ctor and assignment operator private and not implemented.

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Gerri:
move non-persistent member fUrl that was in all derived classes to
TFile. It is accessable via the new method GetEndpointUrl() and will
return in the case of xrootd files the url of the node really having
the file (and not the generic redirector host id).
Also added code to better handle the case of many concurrent async
opens (keep a list of async open handlers).

from Andreas Peters:
I just added a function, GetEndpointUrl(), which allows you to find out
after redirection to which host you are redirected.
So, if you give a list of Alien URLs in a Dataset, the master can try to
open all files over the redirector and will end up at some hosts. It can
then replace the alien url with the url, where it could open the files.
This is cool, because you could set the connection time only to 2s and if
the master cannot open the file, it will just skip it in the dataset.
Or the master would trigger the staging over xroootd ... aso ...
so, if you could put this in soon, would be cool.

using an existing connection (used to optmize the rootd
fall back support in TXNetFile).
net/src/TNetFile.cxx
- add support for new Create()
net/inc/TPSocket.h
- add new constructor to setup a parallel socket using
an existing connection (used to optmize the rootd
fall back support in TXNetFile).

introduce a more complete TSystem::GetPathInfo() method that takes a
new FileStat_t structure as argument. This FileStat_t structure mimics the
common struct stat. This allows for full support of the file mode bits
(via the new enum EFileModeMask and the inline function R_ISDIR(), R_ISCHR(),
R_SIBLK(), R_ISREG(), R_ISLNK(), R_ISFIFO() and R_ISSOCK()).
The TSystem derived helper clsses for the remote file access protocols
have been updated too (all already supported struct stat in their POSIX
layers). Modified rootd to also support FileStat_t. With this change we
can get rid of machine dependent file permission checking code in several
places, notably in the TGFSContainer, which now can correctly display
file attributes for remote protocols.

Big authentication patch by Gerri:
General purpose:
Add support for 'authenticated' sockets on client side
and prepare for support of server authenticated sockets.
Main changes:
o TSocket, TPsocket:
Added support of 'authenticated' sockets: authentication
is delegated to TSocket by calling a static method
CreateAuthSocket() returning a TSocket*.
TSocket is now the only class calling TAuthenticate.
o TFTP, TNetFile, TSlave:
modified to cope with new socket authentication scheme.
o TAuthDetails replaced by TSecContext containing:
- local authentication info
- expiration time
- pointer to a security context for the method (if any)
- information for cleanup (via TSecContextCleanup)
o A list of valid TSecContext has been added to TROOT,
accessible via gROOT->GetListOfSecContexts().
o THostAuth rewritten using arrays to avoid multiple use
of 'new'; functionality extended by the addition of
several new methods.
o TAuthenticate:
- Loading of information from .rootauthrc has been optimized;
this allowed to simplify method signatures and drop several
methods. Also collection and transmission of authentication
information from TSlave to TProofServ gets simplified by the
new scheme.
- Added support for server dependent directives in .rootauthrc
- Added check for changes in .rootauthrc each time a new
TAuthenticate is instantiated, so that changes in the file
are picked-up interactively.
- Checking for an existing TSecContext (previously TAuthDetails)
has been improved
- Improved diagnostics for SshAuth
- Enlarged support for authentication method indication in protocol:
UsrPwd: rootup/proofup
SRP: roots/proofs (already supported)
Krb5: rootk/proofk (already supported)
Globus: rootg/proofg
SSH: rootsh/proofsh
UigGid: rootug/proofug
o GlobusAuth.cxx, Krb5Auth.cxx, SRPAuth.cxx
- Adapted to new class TSecContext
- Added support for improved search for reusable TSecContext
- Drop globals used to store established security contexts
(saved in TSecContext) and related methods
o Automatic creation of <RootDir>/etc/system.rootauthrc from
compilation flags; this has priority on old envs
'Rootd.Authentication' and 'Proofd.Authentication' and is
superseded by $HOME/.rootauthrc
o Automatic creation of <RootDir>/etc/system.authdaemonrc from
compilation flags; this is superseded by $HOME/.rootauthrc
o rpdutils:
- several almost identical methods moved in from rootd/proofd
- several new methods to simplify manipulation of the
authentication tab file
- moved (and improved) check for running of sshd in RpdSshAuth,
performed only in case of failure (to avoid spurious messages
printed by sshd in /var/log/messages)
o proofd.cxx, rootd.cxx
- increased protocol version
- all initialization stuff (included authentication and
login) done via RpdInitSession
- postpone opening of parallels sockets after authentication
(to solve problem of Kerberos/Globus authentication with
parallel sockets)(rootd)
- Fixed problem with kerberos and globus authentication in rootd
with parallel sockets.

Mega patch to add support for large files (bigger than 2 GBytes)
----------------------------------------------------------------
==========>NEW VERSION 4.00/00 <===========
Because this new version has a considerable number of changes,
and new important additions by Philippe are scheduled for the coming days
we are starting a new major version 4.
-Support for large files
-Automatic schema evolution for foreign classes
-New data type Double32_t
Large files are currently tested only under Linux with gcc3.2.
Support for other systems will be gradually added in the coming days.
By default under Linux, files are created with the option LARGEFILE.
Note that when creating a Tree, the default maximum size for a Tree
is set to 1.9 GBytes. You can change this default value by calling
TTree::SetMaxTreeSize(Long64_t maxsize)
The implementation of this new feature has required changes in many places.
The files produced by this new version can still be read by old ROOT versions
if their size if smaller than 2 GBytes. And obviously, the new version
can digest old ROOT files.
WARNING: note the following backward incompatibility:
-TSystem::GetPathInfo has a new signature: (also TUnixSystem, TWinNTSystem, etc)
old: GetPathInfo(const char *path, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: GetPathInfo(const char *path, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TFile::SysSeek and TFile::SysStat have a new signature (also TNetFile, TWebFile, etc)
old: Int_t SysSeek(Int_t fd, Long_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: Long64_t SysSeek(Int_t fd, Long64_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TTree::SetMaxTreeSize has a new signature:
old: void TTree::SetMaxTreeSize(Int_t maxsize)
new: void TTree::SetMaxTreeSize(Long64_t maxsize)
All references to Seek_t have been replaced by Long64_t.

New TCastorFile: a TCastorFile is like a normal TNetFile except that it
obtains the remote node (disk server) via the CASTOR API, once the
disk server and the local file path are determined, the file will be
accessed via the rootd daemon. File names have to be specified like:
castor:/castor/cern.ch/user/r/rdm/bla.root
The patch level of libshift should be at least 1.5.x (which is the one
installed on all CERN machines in /usr/local).
The CASTOR HSM interface code is provided by Jean-Damien Durand of the
CASTOR team.

new method TFile::ReOpen(Option_t *mode). Reopens a file with a different
access mode, like from READ to UPDATE or from NEW, CREATE, RECREATE, UPDATE
to READ. Thus the mode argument can be either "READ" or "UPDATE". The
method returns 0 in case of success, 1 in case mode did not change and
-1 in case of failure.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.
