◆ CheckDataSetSrvMaps()

Bool_t TDataSetManager::CheckDataSetSrvMaps ( TUrl furl,
TString file1,
TList srvmaplist = 0 
)
static

Check if the dataset server mappings apply to the url defined by 'furl'.

Use srvmaplist if defined, else use the default list. If yes, resolve the mapping into file1 and return kTRUE. Otherwise return kFALSE.

Definition at line 1930 of file TDataSetManager.cxx.

◆ CheckStagedStatus()

Bool_t TDataSetManager::CheckStagedStatus ( TFileInfo fileInfo,
Int_t  fopt,
Int_t  maxfiles,
Int_t  newstagedfiles,
TFileStager stager,
Bool_t  createStager,
Bool_t  dbg,
Bool_t changed,
Bool_t touched,
Bool_t disappeared 
)
static

Check stage status of the file described by "fileInfo".

fopt is same as "fopt" in TDataSetManager::ScanDataSet, which is repeated below: The int fopt controls which files have to be processed (or added to the list if ropt is 1 - see below); 'fopt' is defined in term of csopt and fsopt: fopt = sign(fsopt) * csopt * 100 + fsopt where 'fsopt' controls the actual selection -1 all files in the dataset 0 process only files marked as 'non-staged' >=1 as 0 but files that are marked 'staged' are open >=2 as 1 but files that are marked 'staged' are touched 10 process only files marked as 'staged'; files marked as 'non-staged' are ignored and 'csopt' controls if an actual check on the staged status (via TFileStager) is done 0 check that the file is staged using TFileStager 1 do not hard check the staged status (example: use fopt = -101 to check the staged status of all the files, or fopt = 110 to re-check the stage status of all the files marked as staged)

If 'dbg' is true, some information about the ongoing operations is reguraly printed; this can be useful when processing very large datasets, an operation which can take a very long time.

If maxfiles > 0, select for processing a maximum of 'filesmax' files (but if fopt is 1 or 2 all files marked as 'staged' are still open or touched)

Return code kTRUE the file appears newly staged kFALSE otherwise

changed is true if the fileinfo is modified touched is true if the file is open and read disappeared is true if the file is marked staged but actually not staged

◆ GetDataSets()

TMap * TDataSetManager::GetDataSets ( const char *  uri,
UInt_t  = TDataSetManager::kExport

void TDataSetManager::ParseInitOpts ( const char *  opts)
virtual

Parse the opts string and set the init bits accordingly Available options: Cq: set kCheckQuota Ar: set kAllowRegister Av: set kAllowVerify Ti: set kTrustInfo Sb: set kIsSandbox Ca: set kUseCache or kDoNotUseCache The opts string may also contain additional unrelated info: in such a case the field delimited by the prefix "opt:" is analyzed, e.g.

if opts is "/tmp/dataset opt:Cq:-Ar: root://lxb6046.cern.ch" only the substring "Cq:-Ar:" will be parsed .

Reimplemented in TDataSetManagerFile.

◆ ParseUri()

Bool_t TDataSetManager::ParseUri ( const char *  uri,
TString dsGroup = 0,
TString dsUser = 0,
TString dsName = 0,
TString dsTree = 0,
Bool_t  onlyCurrent = kFALSE,
Bool_t  wildcards = kFALSE 
)

Parses a (relative) URI that describes a DataSet on the cluster.

The input 'uri' should be in the form '[[/group/]user/]dsname[#[subdir/]objname]', where 'objname' is the name of the object (e.g. the tree name) and the 'subdir' is the directory in the file wher it should be looked for. After resolving against a base URI consisting of proof://masterhost/group/user/

  • meaning masterhost, group and user of the current session - the path is checked to contain exactly three elements separated by '/': group/user/dsname If wildcards, '*' is allowed in group and user and dsname is allowed to be empty. If onlyCurrent, only group and user of current session are allowed. Only non-null parameters are filled by this function. Returns kTRUE in case of success.

'process' field: N, noaction: do nothing on the selected files P, fullproc: open the selected files and extract the meta information L, locateonly: only locate the selected files S, stageonly: issue a stage request for the selected files not yet staged

'auxiliary' field V, verbose: notify the actions

◆ ScanDataSet() [3/3]

Int_t TDataSetManager::ScanDataSet ( TFileCollection dataset,
Int_t  fopt,
Int_t  sopt = 0,
Int_t  ropt = 0,
Bool_t  dbg = kFALSE,
Int_t touched = 0,
Int_t opened = 0,
Int_t disappeared = 0,
TList flist = 0,
Long64_t  avgsz = -1,
const char *  mss = 0,
Int_t  maxfiles = -1,
const char *  stageopts = 0 
)
static

Go through the files in the specified dataset, selecting files according to 'fopt' and doing on these files the actions described by 'sopt'.

If required, the information in 'dataset' is updated.

The int fopt controls which files have to be processed (or added to the list if ropt is 1 - see below); 'fopt' is defined in term of csopt and fsopt: fopt = sign(fsopt) * csopt * 100 + fsopt where 'fsopt' controls the actual selection -1 all files in the dataset 0 process only files marked as 'non-staged' >=1 as 0 but files that are marked 'staged' are open >=2 as 1 but files that are marked 'staged' are touched 10 process only files marked as 'staged'; files marked as 'non-staged' are ignored and 'csopt' controls if an actual check on the staged status (via TFileStager) is done 0 check that the file is staged using TFileStager 1 do not hard check the staged status (example: use fopt = -101 to check the staged status of all the files, or fopt = 110 to re-check the stage status of all the files marked as staged)

If 'dbg' is true, some information about the ongoing operations is reguraly printed; this can be useful when processing very large datasets, an operation which can take a very long time.

The int 'sopt' controls what is done on the selected files (this is effective only if ropt is 0 or 2 - see below): -1 no action (fopt = 2 and sopt = -1 touches all staged files) 0 do the full process: open the files and fill the meta-information in the TFileInfo object, including the end-point URL 1 only locate the files, by updating the end-point URL (uses TFileStager::Locate which is must faster of an TFile::Open) 2 issue a stage request on the files

The int 'ropt' controls which actions are performed: 0 do the full process: get list of files to process and process them 1 get the list of files to be scanned and return it in flist 2 process the files in flist (according to sopt) When defined flist is under the responsability the caller.

If avgsz > 0 it is used for the final update of the dataset global counters.

If 'mss' is defined use it to initialize the stager (instead of the Url in the TFileInfo objects)

If maxfiles > 0, select for processing a maximum of 'filesmax' files (but if fopt is 1 or 2 all files marked as 'staged' are still open or touched)

Return code 1 dataset was not changed 2 dataset was changed

The number of touched, opened and disappeared files are returned in the respective variables, if these are defined.

◆ ScanFile()

Int_t TDataSetManager::ScanFile ( TFileInfo fileinfo,
Bool_t  dbg 
)
static

Open the file described by 'fileinfo' to extract the relevant meta-information.

Return 0 if OK, -2 if the file cannot be open, -1 if it is corrupted

◆ ShowCache()

Int_t TDataSetManager::ShowCache ( const char *  uri)
virtual

Show cached information matching uri.

Reimplemented in TDataSetManagerFile, and TDataSetManagerAliEn.

Definition at line 795 of file TDataSetManager.cxx.

◆ ShowDataSets()

void TDataSetManager::ShowDataSets ( const char *  uri = "*",
const char *  opt = "" 
)
virtual

Prints formatted information about the dataset 'uri'.

The type and format of output is driven by 'opt':

  1. opt = "server:srv1[,srv2[,srv3[,...]]]" Print info about the subsets of 'uri' on servers srv1, srv2, ...
  2. opt = "servers[:exclude:srv1[,srv2[,srv3[,...]]]]" Print info about the subsets of 'uri' on all servers, except the ones in the exclude list srv1, srv2, ...
  3. opt = <any> Print info about all datasets matching 'uri'

If 'opt' contains 'full:' the list of files in the datasets are also printed. In case 3. this is enabled only if 'uri' matches a single dataset.

In case 3, if 'opt' contains 'full:' the list of files in the datasets are also printed. 'forcescan:' the dataset are open to get the information; otherwise the pre-processed information is used. 'noheader:' the labelling header is not printed; usefull when to chain several printouts 'noupdate:' do not update the cache (which may be slow on very remote servers) 'refresh:' refresh the information (requires appropriate credentials; typically it can be done only for owned datasets)
