From David Dagenhart:
Implement an option to allow ROOT to use the LZMA compression
algorithm to compress data instead of the ZLIB compression algorithm.
LZMA compression typically results in smaller files, but takes more
CPU time to compress data. To use the new feature, the external XZ
package must be installed when ROOT is configured and built:
Download 5.0.3 from here http://tukaani.org/xz/
and make sure to configure with fPIC:
./configure CFLAGS='-fPIC'
Then the client C++ code must call routines to explicitly request LZMA
compression.
ZLIB compression is still the default.
Setting the Compression Level and Algorithm:
There are three equivalent ways to set the compression level and
algorithm. For example, to set the compression to the LZMA algorithm
and compression level 5.
1. TFile f(filename, option, title);
f.SetCompressionSettings(ROOT::CompressionSettings(ROOT::kLZMA, 5));
OR
2. TFile f(filename, option, title, ROOT::CompressionSettings(ROOT::kLZMA, 5));
OR
3. TFile f(filename, option, title);
f.SetCompressionAlgorithm(ROOT::kLZMA);
f.SetCompressionLevel(5);
These methods work for TFile, TBranch, TMessage, TSocket, and TBufferXML.
The compression algorithm and level settings only affect compression of
data after they have been set. TFile passes its settings to its branches
only at the time the branches are created. This can be overidden by
explicitly setting the level and algorithm for the branch. These classes
also have the following methods to access the algorithm and level for
compression.
Int_t GetCompressionAlgorithm() const;
Int_t GetCompressionLevel() const;
Int_t GetCompressionSettings() const;
If the compression level is set to 0, then no compression will be
done. All of the currently supported algorithms allow the level to be
set to any value from 1 to 9. The higher the level, the larger the
compression factors will be (smaller compressed data size). The
tradeoff is that for higher levels more CPU time is used for
compression and possibly more memory. The ZLIB algorithm takes less
CPU time during compression than the LZMA algorithm, but the LZMA
algorithm usually delivers higher compression factors.
The header file core/zip/inc/Compression.h declares the function
"CompressionSettings" and the enumeration for the algorithms.
Currently the following selections can be made for the algorithm:
kZLIB (1), kLZMA (2), kOldCompressionAlgo (3), and kUseGlobalSetting
(0). The last option refers to an older interface used to control the
algorithm that is maintained for backward compatibility. The following
function is defined in core/zip/inc/Bits.h and it set the global
variable.
R__SetZipMode(int algorithm)
If the algorithm is set to kUseGlobalSetting (0), the global variable
controls the algorithm for compression operations. This is the
default and the default value for the global variable is kZLIB.
Note that the LZMA algorithm will only be available if the LZMA
libraries from the XZ package were available when the ROOT executable
being used was configured and built. If you are building ROOT and want
LZMA then you must do something similar to the following if XZ is not
already installed on your system.
Download XZ version 5.0.3 from http://tukaani.org/xz/
unwind the tarball
cd xz-5.0.3
./configure CFLAGS='-fPIC'
make
ROOT was tested with version 5.0.3 of XZ. It might work with earlier
versions and will probably work with later versions of XZ.
Then either use "make install" to put the library and headers into
/usr/local/* so the scripts building ROOT can find them or use
arguments to the ROOT configure script to point to the proper
directories containing the XZ library and headers. These are the
library and the included header (lzma.h includes other headers in the
lzma subdirectory).
src/liblzma/.libs/liblzma.a
src/liblzma/api/lzma.h
WARNING: Data compressed with the LZMA algorithm cannot be read by
ROOT executables that were not built with LZMA support.

From Gerri:
Few fixes to improve/reduce verbosity in case of connection broken or
reset by peer
- In TSocket:
- Add bit kBrokenConn and set it when the connection is broken or reset
by peer
- Add missing checks of return codes from Send and Recv operations
- In CreateAuthSocket, add an optional argument to extract the error code
in case of failure; set the error to kErrConnectionRefused when the
failure is due to a broken or reset by peer connection.
- In TPSocket:
- Add bit kBrokenConn and set it when the connection is broken or reset
by peer
- Add missing checks of return codes from Send and Recv operations
- In the main constructor, fix a bug causing a double connection attempt
in case of failure
- In TNetFile:
- Extract a more correct error code via CreateAuthSocket instead of
setting the generic authentication error code
- Fix a typo in a error message
- In TNetSystem:
- Fix a bug in ConsistentWith causing always a new helper (and connection)
instance to be created when repeating the request with the same path.

From Gerri:
The return of kinit was implicit checked by the subsequent
check valid credentials; I made it explicit.
However, the real problem was elsewhere: in TPSocket, in
case of failed authentication, I forgot to set a flag to
false, so it was trying Init() and hanging at
TServerSocket::Accept. This was introduced last week.

allow TMessages to be compressed before sending them. To have a specific
message compressed use TMessage::SetCompressionLevel(n) where 0 < n <= 9,
like for TFile::SetCompressionLevel(). To have all messages send over
a specific TSocket compressed, use TSocket::SetCompressionLevel().
When a compressed message is received it is automatically uncompressed.
See modified tutorials/hclient.C on how this feature is used.

o Added support for creation of authentication tokens
exclusive to parent daemon and its childs; by default
tokens have inclusive nature, i.e. can be checked by another

(option -E to rootd/proofd)
o Added support for non-standard file name for daemon access rules
(option -D <rootdaemonrc> to rootd/proofd)
o Added support for non-standard file name for authentication directives
(PROOF only: option -A [<rootauthrc>] to proofd; see header of
proofd/src/proofd.cxx)
o Improved security in ssh authentications
Bug fixes:
o Fix a few inconsistencies in treating error conditions
o Fix bug with default init strings for ProxyDuration and ProxyKeyBits
o Fix problem with checking for valid globus proxies
o fixed message desynchronization problem in case of non valid offset
o Modified error call in case of failure of Krb5 initialization:
execution continues (call Err instead of ErrFatal)
o Fix (again) problem with cygwingcc definition in rpdutils.cxx
o Fix problem with fgUser not being correctly saved in case
of successful authentication in TAuthenticate.cxx
o Fix a problem with duplication in socket list (TPSocket)
o Set fContext=0 after deletion TPwdCtx (in TSecContext::Deactivate).
o Fix link problem with the globus patched function in rootd/Module.mk
and proofd/Module.mk
o Added function ProofdTerm (equivalent of RootdTerm) to terminate
correctly in case of interrupting signal SIGTERM or SIGINT (proofd.cxx)
o Fix several incorrect comments.

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.

two new classes supporting parallel socket operation. Using this technique
network transfers are striped over a set of parallel sockets thereby
dramatically increasing the network performance over fat pipes (grid like
infrastructure). Instead of waiting for an ACK before sending a next
fragment and thereby not filling up the pipe completely, the sockets
send fragments in parallel, keeping the pipe full. These two new classes
have the same interface as the standard TSocket and TServerSocket classes.
