TProofLite Class Reference

This class starts a PROOF session on the local machine: no daemons, client and master merged, communications via UNIX-like sockets.

By default the number of workers started is NumberOfCores+1; a different number can be forced on construction.

const char *  confdir = kPROOF_ConfDir,
Int_t  loglevel = 0,
const char *  alias = 0,
TProofMgr mgr = 0 
)

Create a PROOF environment.

Starting PROOF involves either connecting to a master server, which in turn will start a set of slave servers, or directly starting as master server (if master = ""). Masterurl is of the form: [proof[s]://]host[:port]. Conffile is the name of the config file describing the remote PROOF cluster (this argument alows you to describe different cluster configurations). The default is proof.conf. Confdir is the directory where the config file and other PROOF related files are (like motd and noproof files). Loglevel is the log level (default = 1). User specified custom config files will be first looked for in $HOME/.conffile.

Member Function Documentation

◆ CancelStagingDataSet()

Bool_t TProofLite::CancelStagingDataSet ( const char *  dataset)
virtual

Cancels a dataset staging request.

Returns kTRUE on success, kFALSE on failure. Dataset not found equals to a failure. PROOF-Lite re-implementation of the equivalent function in TProofServ.

Reimplemented from TProof.

Definition at line 2195 of file TProofLite.cxx.

◆ CleanupSandbox()

Int_t TProofLite::CleanupSandbox ( )
private

Remove old sessions dirs keep at most 'Proof.MaxOldSessions' (default 10)

Definition at line 1821 of file TProofLite.cxx.

◆ ClearCache()

void TProofLite::ClearCache ( const char *  file = 0)
virtual

Remove files from all file caches.

Reimplemented from TProof.

Definition at line 1519 of file TProofLite.cxx.

◆ ClearDataSetCache()

void TProofLite::ClearDataSetCache ( const char *  dataset = 0)
virtual

Clear the content of the dataset cache, if any (matching 'dataset', if defined).

Reimplemented from TProof.

Definition at line 2282 of file TProofLite.cxx.

◆ CopyMacroToCache()

Int_t TProofLite::CopyMacroToCache ( const char *  macro,
Int_t  headerRequired = 0,
TSelector **  selector = 0,
Int_t  opt = 0,
TList wrks = 0 
)
protected

Copy a macro, and its possible associated .h[h] file, to the cache directory, from where the workers can get the file.

If headerRequired is 1, return -1 in case the header is not found. If headerRequired is 0, try to copy header too. If headerRequired is -1, don't look for header, only copy macro. If the selector pionter is not 0, consider the macro to be a selector and try to load the selector and set it to the pointer. The mask 'opt' is an or of ESendFileOpt: kCpBin (0x8) Retrieve from the cache the binaries associated with the file kCp (0x10) Retrieve the files from the cache Return -1 in case of error, 0 otherwise.

Definition at line 1593 of file TProofLite.cxx.

◆ CreateSandbox()

Int_t TProofLite::CreateSandbox ( )
private

Create the sandbox for this session.

Definition at line 880 of file TProofLite.cxx.

◆ DrawSelect()

Long64_t TProofLite::DrawSelect ( TDSet dset,
const char *  varexp,
const char *  selection = "",
Option_t option = "",
Long64_t  nentries = -1,
Long64_t  first = 0 
)
virtual

Execute the specified drawing action on a data set (TDSet).

Event- or Entry-lists should be set in the data set object using TDSet::SetEntryList. Returns -1 in case of error or number of selected events otherwise.

Reimplemented from TProof.

Definition at line 1053 of file TProofLite.cxx.

◆ ExistsDataSet()

Bool_t TProofLite::ExistsDataSet ( const char *  uri)
virtual

Returns kTRUE if 'dataset' described by 'uri' exists, kFALSE otherwise.

Reimplemented from TProof.

Definition at line 2031 of file TProofLite.cxx.

◆ FindUniqueSlaves()

void TProofLite::FindUniqueSlaves ( )
privatevirtual

Add to the fUniqueSlave list the active slaves that have a unique (user) file system image.

This information is used to transfer files only once to nodes that share a file system (an image). Submasters which are not in fUniqueSlaves are put in the fNonUniqueMasters list. That list is used to trigger the transferring of files to the submaster's unique slaves without the need to transfer the file to the submaster.

Reimplemented from TProof.

Definition at line 2450 of file TProofLite.cxx.

◆ GetDataSet()

TFileCollection * TProofLite::GetDataSet ( const char *  uri,
const char *  = 0

Reimplemented from TProof.

Definition at line 1873 of file TProofLite.cxx.

◆ GetNumberOfWorkers()

Int_t TProofLite::GetNumberOfWorkers ( const char *  url = 0)
static

Static method to determine the number of workers giving priority to users request.

Otherwise use the system information, if available, or just start the minimal number, i.e. 2 .

Definition at line 406 of file TProofLite.cxx.

◆ GetStagingStatusDataSet()

TFileCollection * TProofLite::GetStagingStatusDataSet ( const char *  dataset)
virtual

Obtains a TFileCollection showing the staging status of the specified dataset.

A valid dataset manager and dataset staging requests repository must be present on the endpoint. PROOF-Lite version of the equivalent function from TProofServ.

Reimplemented from TProof.

Definition at line 2223 of file TProofLite.cxx.

◆ GetTreeHeader()

TTree * TProofLite::GetTreeHeader ( TDSet dset)
virtual

Creates a tree header (a tree with nonexisting files) object for the DataSet.

Reimplemented from TProof.

Definition at line 2397 of file TProofLite.cxx.

Start the PROOF environment.

Starting PROOF involves either connecting to a master server, which in turn will start a set of slave servers, or directly starting as master server (if master = ""). For a description of the arguments see the TProof ctor. Returns the number of started master or slave servers, returns 0 in case of error, in which case fValid remains false.

◆ Process() [3/8]

Long64_t TProofLite::Process ( const char *  dsetname,
const char *  selector,
Option_t option = "",
Long64_t  nentries = -1,
Long64_t  first = 0,
TObject elist = 0 
)
inlinevirtual

Process a dataset which is stored on the master with name 'dsetname'.

The syntax for dsetname is name[#[dir/]objname], e.g. "mydset" analysis of the first tree in the top dir of the dataset named "mydset" "mydset#T" analysis tree "T" in the top dir of the dataset named "mydset" "mydset#adir/T" analysis tree "T" in the dir "adir" of the dataset named "mydset" "mydset#adir/" analysis of the first tree in the dir "adir" of the dataset named "mydset" The component 'name' in its more general form contains also the group and user name following "/<group>/<user>/<dsname>". Each of these components can contain one or more wildcards '*', in which case all the datasets matching the expression are added together as a global dataset (wildcard support has been added in version 5.27/02). The last argument 'elist' specifies an entry- or event-list to be used as event selection. It is also possible (starting w/ version 5.27/02) to run on multiple datasets at once in a more flexible way that the one provided by wildcarding. There are three possibilities: 1) specifying the dataset names separated by the OR operator '|', e.g. dsetname = "<dset1>|<dset2>|<dset3>|..." in this case the datasets are a seen as a global unique dataset 2) specifying the dataset names separated by a ',' or a ' ', e.g. dsetname = "<dset1>,<dset2> <dset3>,..." in this case the datasets are processed one after the other and the selector is notified when switching dataset via a bit in the current processed element. 3) giving the path of a textfile where the dataset names are specified on one or multiple lines; the lines found are joined as in 1), unless the filepath is followed by a ',' (i.e. p->Process("datasets.txt,",...) with the dataset names listed in 'datasets.txt') in which case they are treated as in 2); the file is open in raw mode with TFile::Open and therefore it cane be remote, e.g. on a Web server. Each <dsetj> has the format specified above for the single dataset processing, included wildcarding (the name of the tree and subdirectory must be same for all the datasets). In the case of multiple datasets, 'elist' is treated a global entry list. It is possible to specify per-dataset entry lists using the syntax "mydset[#adir/[T]]?enl=entrylist" or "mydset[#adir/[T]]<<entrylist" Here 'entrylist' is a tag identifying, in the order : i. a named entry-list in the input list or in the input data list ii. a named entry-list in memory (in gDirectory) iii. the path of a file containing the entry-list to be used In the case ii) and iii) the entry-list object(s) is(are) added to the input data list. The return value is -1 in case of error and TSelector::GetStatus() in in case of success.
