Member Function Documentation

AttachSession() [1/2]

TProof * TXProofMgr::AttachSession ( Int_t  id, Bool_t  gui = kFALSE  )

inlinevirtual

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.

Reimplemented from TProofMgr.

Definition at line 63 of file TXProofMgr.h.

AttachSession() [2/2]

TProof * TXProofMgr::AttachSession ( TProofDesc *  d, Bool_t  gui = kFALSE  )

virtual

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.

Reimplemented from TProofMgr.

Definition at line 185 of file TXProofMgr.cxx.

Cp()

Int_t TXProofMgr::Cp ( const char *  src, const char *  dst = 0, const char *  fmt = 0  )

virtual

Copy files in/out of the sandbox.

Either 'src' or 'dst' must be in the sandbox. Return 0 on success, -1 on error

Reimplemented from TProofMgr.

Definition at line 1751 of file TXProofMgr.cxx.

CpProgress()

void TXProofMgr::CpProgress ( const char *  pfx, Long64_t  bytes, Long64_t  size, TStopwatch *  watch, Bool_t  cr = kFALSE  )

private

Print file copy progress.

Definition at line 1717 of file TXProofMgr.cxx.

DetachSession() [1/2]

void TXProofMgr::DetachSession ( Int_t  id, Option_t *  opt = ""  )

virtual

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.

Reimplemented from TProofMgr.

Definition at line 237 of file TXProofMgr.cxx.

DetachSession() [2/2]

void TXProofMgr::DetachSession ( TProof *  p, Option_t *  opt = ""  )

virtual

Detach session 'p' from its proofserv.

The instance 'p' is invalidated and should be deleted by the caller

Reimplemented from TProofMgr.

Definition at line 281 of file TXProofMgr.cxx.

Exec()

TObjString * TXProofMgr::Exec ( Int_t  action, const char *  what, const char *  how, const char *  where  )

private

Execute 'action' (see EAdminExecType in 'XProofProtocol.h') at 'where' (default master), with options 'how', on 'what'.

The option specified by 'how' are typically unix option for the relate commands. In addition to the unix authorizations, the limitations are:

 action = kRm        limited to the sandbox (but basic dirs cannot be
                     removed) and on files owned by the user in the
                     allowed directories
 action = kTail      option '-f' is not supported and will be ignored

Definition at line 1204 of file TXProofMgr.cxx.

Find()

void TXProofMgr::Find ( const char *  what = "~/", const char *  how = "-type f", const char *  where = 0  )

virtual

Run 'find' on the nodes.

Reimplemented from TProofMgr.

Definition at line 910 of file TXProofMgr.cxx.

GetFile()

Int_t TXProofMgr::GetFile ( const char *  remote, const char *  local, const char *  opt = 0  )

virtual

Get file 'remote' into 'local' from the master.

If opt contains "force", the file, if it exists remotely, is copied in all cases, otherwise a check is done on the MD5sum. If opt contains "silent" standard notificatons are not printed (errors and warnings and prompts still are). Return 0 on success, -1 on error.

Reimplemented from TProofMgr.

Definition at line 1282 of file TXProofMgr.cxx.

GetMssUrl()

const char * TXProofMgr::GetMssUrl ( Bool_t  retrieve = kFALSE )

virtual

Gets the URL to be prepended to paths when accessing the MSS associated with the connected cluster, if any.

The information is retrieved from the cluster the first time or if retrieve is true.

Reimplemented from TProofMgr.

Definition at line 370 of file TXProofMgr.cxx.

GetSessionLogs()

TProofLog * TXProofMgr::GetSessionLogs ( Int_t  isess = 0, const char *  stag = 0, const char *  pattern = "-v \"| SvcMsg\"", Bool_t  rescan = kFALSE  )

virtual

Get logs or log tails from last session associated with this manager instance.

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". If 'rescan' is TRUE, masters will rescan the worker sandboxes for the exact paths, instead of using the save information; may be useful when the ssave information looks wrong or incomplete. Returns a TProofLog object (to be deleted by the caller) on success, 0 if something wrong happened.

Reimplemented from TProofMgr.

Definition at line 593 of file TXProofMgr.cxx.

Grep()

void TXProofMgr::Grep ( const char *  what, const char *  how = 0, const char *  where = 0  )

Init()

Int_t TXProofMgr::Init ( Int_t  loglevel = -1 )

private

Do real initialization: open the connection and set the relevant variables.

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.

Definition at line 123 of file TXProofMgr.cxx.

IsValid()

Bool_t TXProofMgr::IsValid ( ) const

Bool_t TXProofMgr::MatchUrl ( const char *  url )

ReadBuffer() [1/2]

TObjString * TXProofMgr::ReadBuffer ( const char *  fin, const char *  pattern  )

virtual

Read, via the coordinator, 'fin' filtered.

virtual

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.
