Patch automatizing the usage of the file-based technology to handle outputs.
After this patch PROOF users can define as an option to Process an output file for their results
and choose if the merging goes via file or in memory. User can also decide to save theit results
in a set of files identified by a name (dataset).
Administrators can force merging-via-file or can make it conditional to the resident memory exceeding
a given threshold.
The new options are documented at
http://root.cern.ch/drupal/content/handling-outputs
Since TProofOutputFile is now used by TProof, the class has been moved from proof/proofplayer
(libProofPlayer) to proof/proof (libProof).
The selector tutorials/proof/ProofSimple.h,.C has been modified to allo testing the new options,
and a new test has been added to stressProof.

Use by default the official Merge methods for histograms which correctly treats
histograms with labelled axis.
Simple addition was performed for histograms with same axis to overcome a
perfomance penalty due to additional general consistency checks present in
the first version of TH1::Merge. This performance issue has been fixed starting
with 5.32.
Should the issue reported in Savannah #94926.

Simplify enabling of basic feedback.
- In TDrawFeedback::Feedback, call method Draw() of objects not identified as TH1
derivation. This allows user-defined objects implementing Draw to be displayed
via this utility class (request on the forum).
- In TPerfStats, add new histogram TH1I with the packets being processed per worker;
currently this is 0 or 1 but may change in future; it shows which workers are
still active, which may be useful for debugging at the end of query.
- Add new class TStatsFeedback to display in one canvas the distributions for
the events processed per workers, the packets processed per workers and the
packets being processed per worker.
- In TProof::Process, add support for switches "fb=name1,name2,name3,... " or
"feedback=name1,name2,name3,... " in the option field. This enables feedback
for the specified objects, creating a TDrawFeedback object attached to the session.
Feedback for the specified objects is disabled at the end of the query and the
created TDrawFeedback is destroyed.
The special name 'stats' enables the three feedback histograms required by
TStatsFeedback, and uses a TStatsFeedback instead of TDrawFeedback.
The feedback specs are removed from the option field passed to TProofPlayer::Process.

Several optimizations in the low level PROOF event loop (TProofPlayer::Process):
- Per-event calls to TEventIter::GetNextEvent are replaced by per-packet calls
to a new function TEventIter::GetNextPacket and a for loop over the returned
range;
- Progress information is filled in on per-packet pace just before asking for
a new packet, instead of being filled for each event;
- In TProofProgressStatus, the relevant setters in were inlined, and the (expensive)
calls to SetLastUpdate() reduced to the minimum required;
- Status of objects is checked using bits instead of functions calls;
- Check whether to dump memory info is done before calling CheckMemUsage.
These optimizations allow to reduce dramatically the overhead introduced by the
operations PROOF needs to perform during the event loop. A measurement of the
overhead can be obtained from a very light computational task, for example,
generating one random number and filling one histogram; executing this task
within a PROOF-Lite session with 1 worker now takes only 1.8 times the time
required by a straight loop in the parent ROOT session; the same number before
was about 13.
The patch also introduces a couple of small changes enabling the use of
TProofPlayerLocal to process selectors in the local session using the PROOF
iteration mechanism; this is very useful for optimizations studies.
Finally, a couple of missing protections were added in TProofPlayer.

From Taesoo Kim and me.
Add support for selector-by-object processing in PROOF.
The selector object, created and configured locally by the user, is added to the input
list and recuperated from there on the worker machines for processing. Any input list
setting in the selector itself is not streamed but temporarly moved to then standard
input list, so that user can use the selector input list as container of processing
information if they find convenient to do so.
Process(...) methods with the file name argument replaced by 'TSelector *' have
introduced where relevant (TProof, TProofPlayer and their derivatives, TDSet).
Two tests for the new functionality have been added to test/stressProof.cxx (tests 25
and 26).

- Record in TStatus also the max memory usage on the master and printed via TStatus::Print;
this allow a quick visualisation of the overall memroy usage at the end of the query:
root [] TStatus *st = (TStatus *) p->GetOutputList()->FindObject("PROOF_Status");

Max worker virtual memory: 394.90 MB Max worker resident memory: 229.47 MB
Max master virtual memory: 1104.55 MB Max master resident memory: 940.73 MB
- Fix issue in TProofPlayer::HandleHistogram preventing proper histogram cleaning right
after merging when using TH1::Add; histogram were still destroyed at the end of the
query, but there was no memory advantage in TH1::Add wrt TH1::Merge.

In TProofPlayerRemote::HandleHistograms, add support for an option to call directly TH1::Add
if the incoming histogram has the same axis of the one in memory. This allows to avoid going
through the whole Merge machinery for the 99.9% of the cases, considerably speeding up
histogram merging and significantly reducing memory requirements on the master.
This new way is on by default and is controlled by the rootrc 'ProofPlayer.UseTH1Merge' and
by the input list parameter PROOF_UseTH1Merge .

Patch to improve the diagnostic in case of exceptions. Information about the event and file being
processed at the moment the exception was raised is sent to the client, e.g.
0.5: caught exception triggered by signal '1' while processing dset:'EventTree',
file:'http://root.cern.ch/files/data/event_3.root', event:1 - check logs for possible stacktrace
The patch also fixes a problem with submergers observed when a worker was stopped because above
the memory limits: this worker was established as merger but could not do the work, for obvious
reasons, freezing the session.

From Katerina Opocenska:
Patch implementing the new submerger functionality to speed up the merging phase.
At the end of the query, a set of workers are promoted submergers and assigned a
sub-set of workers to merge. Once each sub-merger has merged its sub-set of workers,
it sends its result to the master, which merges the partial results into the final
set of results.
The determination of the sub-mergers is always done dynamically, based on the recent
performance of workers. An optimal (i.e. giving the highest speed-up) number can be
calculated analytically under simpleassumptions.
Merging via submergers is by default disabled. To enable it, with the optimal number
of sub-mergers, one should set the integer parameter 'PROOF_UseMergers' to 0, i.e.
proof->SetParameter("PROOF_UseMergers", 0)
To force S sub-mergers (regardless of the optimal number) do
proof->SetParameter("PROOF_UseMergers", S)

Patch for improved performance monitoring. The 'Rate Plot' button in the progress
dialog is renamed 'Performance plot' and shows up to 4 plots with the event/sec,
the average read chunck size, the number of active workers and the number of active
PROOF sessions on the cluster, all as a function of processing time.
The read chunck size plot allows to monitor the usage of the cache.
The istantaneous processing rate (event/sec) is now better estimate: a few issues
with the normalizing times have ben solved, removing the artificial structures that
were observed.
The possibility to set a max packet time length is introduced (default 30 s); this
can be changes with the parameter PROOF_MaxPacketTime.
The size of the cache is also taken into account to optimize the use of the cache.
The parameter PROOF_UseParallelUnzip has been introduced to toggle the use of the
parallel unzip (default off for now).
A page describing the new performance plots is under preparation at
http://root.cern.ch/drupal/content/progress-dialog

Patch to support automatic creation of a dataset out of files created on the
worker nodes by worker processes. The implementation is an extension of the
functionality of the class TProofOutputFile used for merging via file.
TProofOutputFile:
- Add options to steer the creation of a dataset; the extemded meaning of the
constructor arguments and anew constructor are described in
http://root.cern.ch/drupal/content/handling-large-outputs-root-files
The dataset (i.e. TFileCollection) assembing happens on the master via the
Merge method. Information about the node location of the file is happended
to the relevant TFileInfo as a special "file:" url with option "node=<host-fqdn>:<port>"
This information is needed to facilitate the cleaning of the files once they
are not needed anymore.
The dataset can be just created and returned in the output list, or registered
and/or verified.
TProofPlayerRemote::MergeOutputFiles:
- Correctly transmit the dataset object into the output list
TProofServ:
- Create the new subdirectory 'data' either in the sandbox or followinf ProofServ.DataDir .
- Register and verify the created dataset if required
TProof:
- Implement two new methods:
- ShowData(), to show the content of the assigned 'data' directory
- ClearData(UInt_t what, const char *dsname), to clear all or a subset of the files
in the assigned 'data' directory
Additional changes:
- TProofPlayer:
- Correctly handle the feedback canvas
- Set the drawing attributes
- TProofServ:
- Replace all 'Form("...")' with TString::Format("...") .
- Use the new tag kCollect in debug statements where relevant
- TProof:
- Use the new tag kCollect in debug statements where relevant

TProofDraw
- Do not try to get "htemp" from the input list; this removes a useless warning
TProofPlayer
- Improve the treatment of histogram merging in case of small statistics, i.e. when
the autobinning is not or only partially active. The largest stat histogram is
taken as base for the merging. This is implemented both for output and feedback
histograms, and avoids the large axis boundaries variations observed in such cases.

- Fixes for the asynchronous mode:
- Fully localize the general handling of the input messages into two new methods
TProof::HandleInputMessage(TMessage *) and TProofServ::HandleSocketInput(TMessage *);
these methods are callable form any place that needs to intercept some messages and
do something specific on them (examples are: TProofServ::GetNextPacket, TXProofServ::Get,
TPacketizerAdaptive::ValidateFiles, ...); this allows to remove several duplications
and to make sure that no message is lost or wrongly dispatched.
- Simplify the recursive infrastructure for TProofServ::HandleSocketInput; in particular,
TProofServ::HandleSocketInputDuringProcess is removed as it is a special case of the
HandleSocketInput, saving duplications.
- Always use a kPROOF_CHECKFILE message in replies to check file operations; failures were
signaled with kPROOF_FATAL which may have some undesired side-effects, depending on the
timing
- Add support for one level of recursivity in TProof::Collect .
- Fix a problem with TProof::Finalize when called with default arguments (on the last query)
- In TProof::SendFile, send to unique workers only in the "cache" option is specified
- Remove the call to Finalize for DrawSelect queries, as it is done via the feedback
mechanisms
- Additions/fixes in test/stressProof.cxx:
- New test for the asynchronous mode;
- Fine-tuning of the progress display in batch mode;

First version of PROOFLite, a 2-tier realization of PROOF intended for multi-core
machines. In PROOFLite the client start directly the workers; no daemon is required.
Currently this works on Unix only. Some issues with the internal connection still need
to be sorted out on Windows.
To start a session just use
TProof::Open("") or TProof::Open("lite")
From there on everything should be as in normal PROOF. To start a standard PROOF
session (i.e. via daemons) on the localhost use TProof::Open("localhost").
(The default meaning of "" in TProof::Open() is controlled via the rc value
'Proof.LocalDefault').
To run stressProof with PROOFLite pas the argument 'lite':
./stressProof lite
By default, PROOFLite sets the number of workers equal to the number of cores.
The number of workers is controlled by the rc variable 'ProofLite.Workers'; it can
also be set on the fly with the option "workers=<n>", e.g. TProof::Open("lite?workers=2").
This patch also introduces the rc variable 'Proof.Sandbox' to control the local location
of the sandboxes. The default has been changed from "~/proof" to "~/.proof" to avoid
interferences with possible users' working areas. The sandbox contains the directory
'packages' (with the clients packages; used by standard PROOF and PROOF Lite),
and some directories used only by PROOFLite: 'cache' (binary cache) and 'datasets' with
the datasets. The location of these directories is controlled by the rc variables
'Proof.PackageDir', 'Proof.CacheDir' and 'Proof.DataSetDir'.
The working directory for PROOFLite is in the form workdir=<sandbox>/path-to-current-dir where
~/path/to/current/dir is the directory from where the session in launched. The directory
<workdir> contains the session working dirs (in the form 'session-<host>-<time>-<pid>'),
with the symlink 'last-lite-session' pointing to the last started session, and the 'queries'
directory, with the results of queries started from the current directory.

From Jan:
- Added the possibility to handle removed workers and partly processed packets. When a worker is stopped
while processing a packet it finishes, the current event and the rest of the packet is reassigned to another
worker. This is done via two interfaces:
- TVirtualPacketizer::AddProcessed(TSlave *sl, TProofProgressStatus *st, TList **)
- TVirtualPacketizer::ReassignPacket.
- New class TProofProgressStatus used to keep the query progress stauts in all the TProofPlayer objects and in
TPacketizerAdaptive::TSlaveStat. This class is also used to structure the relevant information send in
kPROOF_GETPACKET and kPROOF_STOPPROCESS messages.
- The class TPacketizerProgressive is removed completely.
- The PROOF protocol version is increased to 19: this is to handle the changes in the kPROOF_STOPPROCESS and
kPROOF_GETPACKET messages in Master - worker communication.

From Jan:
- A new optional version of PROOF with dynamic worker startup.
It can be enabled by the admin or a user with 'Proof.DynamicStartup'.
A session starts only on the master. When a query processing starts
at the master TXProofServ::GetWorkers() is called. It receives a
list of machines from the scheduler and the workers on the
machines are started. The environment is copied from the master
to the workers. It includes: the include and dynamic library paths,
the set of enabled packages as well as the macros loaded by the user.
- A new method TProof::AddWorkers(TList *workers) was added. It adds
the workers just before the query.
- A packet resubmitting mechanism. When a worker dies all the packets
that it processed are resubmitted.
- In TPacketizerAdaptive: fixing initialization of fgMaxSlaveCnt. By
default it was initialized twice.

Summary (see branch logs for more details):
- Set of changes related to CPU quota control including
- broadcast of centrally determined priorities
- mechanism to renice processes in a quantitative way
- New packetizer for non-tree based analysis and related API in TProof (from L. Tran-Thanh)
- Support for merging output objects saved in files on the workers (from L. Tran-Thanh and me)
- Improve version binary compatibility checks using also the SVN revision number
(when available) to define the running version.
- Extend the version binary compatibility checks also to the cached selector binaries.
- Extend TDSet::Lookup so that in case of missing files, it can remove them from the
dataset (option removeMissing must be set).
- Move the data set lookup to the TProofPlayerRemote::Process.
- Handle properly the case of incomple datasets: if the file is not found in the lookup
don't try to validate it; add it, instead, to a 'missingFiles' list returned in the
output list (fixing bug #28800 in Savannah).

(period 1s) instead of at the end of each processed event;
this reduces considerably the overhead when processing many
CPU-light events
- remove some left-over hardcoded settings of the feedback period
- cleanup the stop/abort timer infrastructure

From Gerri:
TVirtualProof.h
- Add abstract methods methods to communicate the data set status
(signal + sender)
pmain.cxx
- Add call to Exit(0). T(X)ProofServ::Terminate() just interrupt the event
loop (insteadof exiting) to avoid problems when the terminate is run in
a separate thread (like in xproofd).
proof/inc/TProof.h
- Add methods methods to communicate the data set status (signal + sender)
- Increase protocol number to 11 (new merging technology)
proof/inc/TProofPlayer.h, .cxx
- Implement new merging technology for the output list to reduce memory
consumption: add methods to directly merge received objects in the
output list
- Polish cleaning of the various temporary lists and objects
TProofServ.h, .cxx
- Implement new merging technology for the output list to reduce memory
consumption: objects are sent one-by-one
- Do not scan for previous query results at Setup (do it when the client
requests for it first); thsi allows to speed up start-up when a large number
of queries is present and also allos to avoid warning due dictionaries
not yet loaded.
- Add method for a global cleanup of old query results.
- Keep in memory only meta information about processed queries (i.e. not the
output list) to avoid large memory consumption in case of large
output lists
- In Terminate, change the call to Exit(0) to ExitLoop() ; Exit(0) is
called in pmain.cxx .
TProof.cxx
- Implement new merging technology for the output list to reduce memory
consumption: objects are received one-by-one and directly merged in the
output list
- Add protection in parallel startup against invelid slaves.
- Remove check on directory existence in UploadDataSet.
- Add methods to handle notifications from data set verification
- Fix inconsistency with notification in activation/deactivation
of non-existing workers
TXProofServ.cxx
- In Terminate, change the call to Exit(0) to ExitLoop() ; Exit(0) is
called in pmain.cxx.
TQueryResult.cxx
- Make a owned copy of the input list (instead of just storing the pointer) to
allow proper cleaning.

Instead of providing default implementations for copy ctor's and assignment
operators we better make them private (and not implemented) to avoid people
from accidentally using them. Especially the collections classes and the
TQObject derived classes. In these classes the default implementations would
cause havoc due to multiple deletions of the same objects and other
potential memory corruptions.

From Gerri:
The patch implements the following new functionality:
- Shutdown of idle sessions when quitting ROOT; if not idle the session
is shutdown as soon as processing terminates; it is possible to delay
the automatic shutdown by a tunable amount of time via a new directive
in the xrootd config file 'xpd.shutdown' (see xpd.cf.example).
- New static method TProof::Reset(const char *url) to hard-cleanup an
user area (implemented for Xproofd only); this implied quite some
additions in XrdProofdProtocol.
- Possibility to temporary remove / re-insert a worker from the active list
TProof::DeactivateWorker(const char *ord)
TProof::ActivateWorker(const char *ord)
with 'ord' the ordinal numer, e.g. "0.3" .
- A default url for the disk pool
const char *TVirtualProof::GetDataPoolUrl()
It is set by default to a string send back by the master, but it can
be changed via
void TVirtualProof::SetDataPoolUrl(const char *url)
Jan should then adapt his code to use this as default.
- Posibility to timeout Collect; for now this is only used at forced
termination.
The patch includes many small changes and bug fixes. One of the most important
is in TXNetSystem (a bug preventing correct treatment of multiple request
to the same redirector).

From Gerri:
This is the patch for Marek's problem.
Basically, ReinitSelector() does not need to be called if running in
synchronous mode (new argument to TProofPlayer::Finalize()), and the aclic
mode must be recorded and used when reinitialization is needed.
It remains the problem with ::GetSelector that I mentioned in the
previous mail, which affects, for example, cases when one runs once
with "<selec>.C+", modifies <selec>.C and runs again forgetting the
'+'.

From Gerri:
Big patch supporting query queueing on the PROOF master, interogation and
interaction with the queue. Retrieval, finalization and archival of query
results and multiple PROOF sessions. Some other fixes:
- TMacro.h, .cxx
add method Checksum to get the MD5 of the current context
(needed for optimized selector reinitialization)
- Changes needed to create and fill the list of data sets (TROOT,
TDSet, TChain, TChainProof)
- A new method TSelector::IsStandardDraw() to check if a selector
is for standard draw actions
- TEventIter: fix for the missing last update (see above)
- Few protections in TPacketizers destructors
- Fix for code conventions in TPerfStats (the other will follow)
- Occasional missing last update of the progress bar (systematically
reproduced with SetParallel(1)): all this part is quite involved
and I have found a solution which does not harm but perhaps is not
the most elegant.
- SetParallel(0): the progress bar was not working at all in such a
case, since no packetizer is involved. Still it is useful to see
that things are not stuck, so I have added some progress messages
there too. The problem is that I have not found a way to get the total
number of entries from a data set without doing all the machinery
done in the packetizer.

From Gerri:
This is the patch to add support for asynchronous queries.
The principal modifications are in TProof and TProofPlayer.
In TProof, I have separated the parsing of the received messages
from the selection of the socket (new method CollectInputFrom()):
the new method is called directly by TProofInputHandler::Notify()
in the case of asynchronous mode.
Also in TProof I have added a method to redirect the logs to a
temporary file, to avoid having them on the main window while doing
something else. The method is TProof::RedirectLog(), it uses freopen,
fdopen and dup2, and works well back and forth.
The content of the temp file can be displayed into a log window
(new GUI class TProofProgressLog), via a new button in the
progress dialog ("Show Logs").
In TProofPlayer I have created a new method Finalize() with the
final part of Process(): this is necessary to be able to finalize
the queries processed asychronously.
There are several many other small changes and fixes: a couple
of non-backward comaptibilities introduced with the previous
patch, many small issues in the GUI (the stop and abort buttons
were never disabled ...).
Also, in view of multi-sessions, it does not make much sense to
have one progress dialog per query: one per session is enough;
I have added a method ResetProgressDialog() to reset it when a
new query is started.
Finally, as anticipation of the next patch, this patch includes
support for a list of queries created by the master and described
by the new class TProofQuery.
The list is displayed by TProof::ShowQueries().

From Marek Biskup:
major new PROOF developments:
- access to PROOF directly via the TChain interface (creating a TDSet
in the background).
- access to PROOF based trees via the TTreeViewer
- fully implemented the TChain/TDSet::Draw() interface.
- PROOF sessions can now be browsed via the TBrowser

From Maarten and Kristjan Gulbrandsen:
Here is the patch with the restructured PROOF code. It parameterizes
PROOF startup, currently implementing "Standard", Condor, MLM and PEAC.
It can easily be extended with other "TProof" classes, e.g. AliEn Proof.
Or what ever next Grid implementation or scheduler comes along.
The MLM, Multi Level Master, code uses a basic packetizer, based on a
MSD (massstorage domain) tag. In MLM mode we have multi-tier client
server setup, like:
client -> super master -> sub master 0 -> slave[0..N]
...
-> sub master M -> slave[0..N]
It also contains a large number of smaller fixes. Credit for most of
the work goes to Kris!
We have tested this on multipe platforms (RH7.3, RH9, SL3) and in
multiple configurations. Should be stable.

*****************WARNING*****************
With this mega patch, we introduce support for TTree/TChain with more than
2 billion entries. Several class data members have been changed from
Int_t (or Stat_t) to Long64_t.
==>Trees written with this new version cannot be read with older versions

From Maarten:
- new class TParameter
- new class TDrawFeedback
- fixes to the feedback of performance histograms
- selection of the packetizer
- cleanups
Example commands:
gROOT->Proof()
... package setup ...
TDSet *d = make_tdset(2)
gEnv->SetValue("Proof.StatsTrace",1)
gEnv->SetValue("Proof.StatsHist",1)
TList *fb = new TList
fb->SetName("FeedbackList")
fb->Add(new TObjString("EventsHist"))
fb->Add(new TObjString("CpuTimeHist"))
TDrawFeedback *dfb = new TDrawFeedback((TProof*)gProof)
gProof->AddInput(fb)
d->Process("EventTree_Proc.C","")

From Maarten and Kristjan Gulbrandsen:
PROOF and file I/O performance monitoring framework. The TVirtualPerfStats
abstract class allows adding monitoring events in base classes (TFile and
TNetfile). The performance monitoring info allows detailed study of PROOF
performance (which files accessed by which slaves, latency, read/write times,
packet size, etc.). The result is send back to the client in the form of a
memory based TTree.
Remove TProofStats.h and TProofStats.cxx, .d, .o from proof/inc and src.

From Philippe:
This update makes any selector created by the TTreePlayer directly from a source file local to the current TTreePlayer
object (instead of being a static).
It also insures that TProofPlayer and TTreePlayer do not call delete for an object of
a class which library was unloaded (since the code is gone, this would lead to a core
dump).

Big (unsigned) long long support patch. Following provided:
- basic typedefs in Rtypes.h: Long64_t and ULong64_t
- basic Long64 I/O support in TBuffer
- automatic Long64 I/O support in TStreamerInfo
- Long64 byteswap in Bytes.h
- Long64 type handling in classes like TDataMember, TDataType, TCint,
TROOT, etc
- Removal of obsolete Long64_t typedefs in many PROOF classes
No changes for non-Long64 data types (no backward incompatibilies).
I/O tested for Long64 basic type, and static and dynamic arrays using
handcoded streamers, rootcint generated streamers and automatic StreamerInfo
streamers.

relocate some proof file to remove circular dependencies between the
treeplayer and proof shared libraries. Also rename TPlayer to TProofPlayer
et al. Also remove Begin() from TSelector, use Begin(0) instead. This to
be backward compatible with existing TSelector scripts that don't have
Begin() and therefor give warnings about Begin() being hidden in the base
class.
