From Constantin Loizides
This patch implements:
- decentralized, automatic mutex initialization,
see R__LOCKGUARD2 in TVirtualMutex
- PROOF parallel startup fixes
- more thread protection (in base, cont, meta, rest to be done)
- cleanups
From Eddy Offermann:
TString::Atoi and Atof are made const.

From Gerri:
Patch introducing parallel startup of the slave servers. This new feature
will considerably reduce the startup time in PROOF setups with many 10's
to 100's of slaves. By default this feature is off, turn it on in the
[system].rootrc file by uncommenting the line:
Proof.ParallelStartup: yes
Summary of changes:
Index: Makefile
- Add the thread lib to PROOFLIBS
Index: base/inc/TVirtualMutex.h, base/src/TVirtualMutex.cxx
- Add global mutexes to protect printing and authentication
Index: base/src/TError.cxx
- Protect static buffer in DebugPrint with specific global mutex
Index: config/Makefile.depend
- Add dependence on thread lib for PROOF
Index: config/rootrc.in
- Add description of new envs
Proof.ParallelStartup, Auth.Timeout, ProofServ.UseSSH
Index: net/inc/TAuthenticate.h
- Add new member fTimeout to indicate timeout situations
and new method HasTimedOut() to retrieve it.
- Add new static member with the timeout value in sec
and method SetTimeOut() to set it
- Add new method CatchTimeOut() called at timeout expiration
Index: net/inc/THostAuth.h , net/src/THostAuth.cxx
- Add new method SetLast() to lower pririty of an attempted
protocol that has timed-out
Index: net/src/TAuthenticate.cxx
- Implementation of the new timeout setup using TTimer
- Add protection using specific global mutex
- change to start with lower case some local variables
in Authenticate
- re-introduce call to THostAuth::CountFailure() (which got
lost in a previous patch)
- Disable by default SSH for PROOF servers
- fix a couple of small memory leaks
Index: net/src/TPSocket.cxx
- Fix logic in Close() (if called too early (e.g. timeout)
the underlying socket can still be open and needs to be
closed).
Index: net/src/TSocket.cxx
- initialize member fTcpWindowSize in all constructors
- modify error logging after an unsuccessful authentication
attempt, checking for timeouts.
- disable SSH for PROOF servers
Index: proof/inc/TProof.h
- patch for parallel startup using threads:
- new methods SlaveStartupThread(void *) and
SubmasterStartupThread(void *) executed in threads
- add Bool_t argument to all implementations of StartSlaves
Index: proof/src/TProof.cxx
- patch for parallel startup using threads:
- add internal classes ProofThread and ProofThreadArg to keep
track of started threads and to pass arguments to threads
- cleanup fPlayer and fFeedBack in destructor
Index: rpdutils/src/rpdutils.cxx
- fix small memory leak
Index: thread/src/TThread.cxx
- initialize new global mutexes

Patch from Mathieu de Naurois adding Thread-safety in many ROOT classes.
A new TVirtualMutex global is defined in TVirtualMutex.h (gCINTmutex).
gCINTMutes is used in TMethodCall to protect concurrent access to CINT.
The R__LOCKGUARD macro is introduced in many classes to check for a mutex.
The performance penalty introduced by the MUTEX logic
-is ZERO in the application has no threads
-about 10% in case of threads

Original Path:

File length: 2361 byte(s)
introduce new abstract class TVirtualMutex in base and move TLockGuard from
thread to base. TMutex now derives from TVirtualMutex. Also add zero
overhead macros to be used to place mutexes (zero overhead in case ROOT
is not compiled with thread support). Added, example, global container
mutex which should be initialized when libThread is loaded to point to
a real mutex. To be done and tested by Mathieu de Naurois.
