class TXProofMgr: public TProofMgr, public TXHandler


The PROOF manager interacts with the PROOF server coordinator to
create or destroy a PROOF session, attach to or detach from
existing one, and to monitor any client activity on the cluster.
At most one manager instance per server is allowed.

Function documentation

TXProofMgr(const char* url, Int_t loglevel = -1, const char* alias = "")
 Create a PROOF manager for the standard (old) environment.
Int_t Init(Int_t loglevel = -1)
 Do real initialization: open the connection and set the relevant
 Login and authentication are dealt with at this level, if required.
 Return 0 in case of success, 1 if the remote server is a 'proofd',
 -1 in case of error.
 Destructor: close the connection
void SetInvalid()
 Invalidate this manager by closing the connection
TProof * AttachSession(TProofDesc *d, Bool_t gui)
 Dummy version provided for completeness. Just returns a pointer to
 existing session 'id' (as shown by TProof::QuerySessions) or 0 if 'id' is
 not valid. The boolena 'gui' should be kTRUE when invoked from the GUI.
void DetachSession(Int_t id, Option_t *opt)
 Detach session with 'id' from its proofserv. The 'id' is the number
 shown by QuerySessions. The correspondent TProof object is deleted.
 If id == 0 all the known sessions are detached.
 Option opt="S" or "s" forces session shutdown.
void DetachSession(TProof *p, Option_t *opt)
 Detach session 'p' from its proofserv. The instance 'p' is invalidated
 and should be deleted by the caller
Bool_t MatchUrl(const char* url)
 Checks if 'url' refers to the same 'user@host:port' entity as the URL
 in memory. TProofMgr::MatchUrl cannot be used here because of the
 'double' default port, implying an additional check on the port effectively
void ShowWorkers()
 Show available workers
TList * QuerySessions(Option_t* opt = "S")
 Get list of sessions accessible to this manager
Bool_t HandleInput(const void* )
 Handle asynchronous input on the socket
Bool_t HandleError(const void* in = 0)
 Handle error on the input socket
Int_t Reset(Bool_t hard = kFALSE, const char* usr = 0)
 Send a cleanup request for the sessions associated with the current user.
 If 'hard' is true sessions are signalled for termination and moved to
 terminate at all stages (top master, sub-master, workers). Otherwise
 (default) only top-master sessions are asked to terminate, triggering
 a gentle session termination. In all cases all sessions should be gone
 after a few (2 or 3) session checking cycles.
 A user with superuser privileges can also asks cleaning for an different
 user, specified by 'usr', or for all users (usr = *)
 Return 0 on success, -1 in case of error.
TProofLog * GetSessionLogs(Int_t ridx = 0, const char* stag = 0, const char* pattern = "-v \"| SvcMsg\"")
 Get logs or log tails from last session associated with this manager
 The arguments allow to specify a session different from the last one:
      isess   specifies a position relative to the last one, i.e. 1
              for the next to last session; the absolute value is taken
              so -1 and 1 are equivalent.
      stag    specifies the unique tag of the wanted session
 The special value stag = "NR" allows to just initialize the TProofLog
 object w/o retrieving the files; this may be useful when the number
 of workers is large and only a subset of logs is required.
 If 'stag' is specified 'isess' is ignored (unless stag = "NR").
 If 'pattern' is specified only the lines containing it are retrieved
 (remote grep functionality); to filter out a pattern 'pat' use
 pattern = "-v pat".
 Returns a TProofLog object (to be deleted by the caller) on success,
 0 if something wrong happened.
TObjString * ReadBuffer(const char* file, Long64_t ofs, Int_t len)
 Read, via the coordinator, 'len' bytes from offset 'ofs' of 'file'.
 Returns a TObjString with the content or 0, in case of failure
TObjString * ReadBuffer(const char* file, const char* pattern)
 Read, via the coordinator, lines containing 'pattern' in 'file'.
 Returns a TObjString with the content or 0, in case of failure
void ShowROOTVersions()
 Display what ROOT versions are available on the cluster
void SetROOTVersion(const char* tag)
 Set the default ROOT version to be used
Int_t SendMsgToUsers(const char* msg, const char* usr = 0)
 Send a message to connected users. Only superusers can do this.
 The first argument specifies the message or the file from where to take
 the message.
 The second argument specifies the user to which to send the message: if
 empty or null the message is send to all the connected users.
 return 0 in case of success, -1 in case of error
Bool_t IsValid() const
{ return fSocket; }
TProof * AttachSession(Int_t id, Bool_t gui = kFALSE)
{ return TProofMgr::AttachSession(id, gui); }
