The `R__HAS_ROOFIT_MULTIPROCESS` is not used in any public header files, so it's not needed. In the RooFit implementation, it is replaced with a `ROOFIT_MULTIPROCESS` define that is part of the RooFitCore target. The `R__HAS_ROOFIT_MULTIPROCESS` was only introduced in ROOT 6.26 and it was never advocated to users, so it should be safe to remove it.
The `roofitmore` is only compiled anyway if mathmore is available.
In RooFit, there are checks if ROOT is build with CUDA only in the `.cxx` implementation files, not in the public headers. We therefore don't need a `R__HAS_CUDA` in the ROOT configuration. The `R__HAS_CUDA` flag was only introduced in ROOT 6.26 and it was never advocated to users, so it should be safe to remove it.
This commit enables serialization of the Python proxy defined within cppyy to the C++ std::runtime_error class. By doing so, we avoid errors that happen in certain configurations of Dask tasks where a std::runtime_error may be thrown within the event loop itself. Recent CI failures report the following: ``` RDataFrame::Run: event loop was interrupted Warning in <TBufferFile::WriteObjectAny>: since runtime_error has no public constructor which can be called without argument, objects of this class can not be read with the current library. You will need to add a default constructor before attempting to read it. Warning in <TStreamerInfo::Build>: runtime_error: base class exception has no streamer or dictionary it will not be saved Warning in <TStreamerInfo::Build>: runtime_error: __cow_string has no streamer or dictionary, data member "_M_msg" will not be saved Error in <TClass::New>: cannot create object of class runtime_error Error in <TBufferFile::ReadObject>: could not create object of class runtime_error *** Break *** segmentation violation ``` This is due to the fact that for some reason the std::runtime_error object is serialized at the end of the function scope within the Dask task. The culprit is the [tblib](https://github.com/ionelmc/python-tblib) Python package, a dependency of Dask. Its most recent version (3.0.0) released on October 22th changes the pickling behaviour of exception objects, which is now evidently more enforced than before. Downgrading to previous versions of tblib make the errors above disappear in the distributed RDataFrame tests.
TGraph2DPainter keep pointers on TGraph2D data, but was not checking if these values were changed. Fixes problem reported https://root-forum.cern.ch/t/56816/
When searching for a new point between p1 and p2, if MnCross fails, retry using a position closer to p1 instead of the middle. Thsi is what is done in old TMinuit. Minuit2 was trying to switch direction of the search and this was causing finding points in the opposite side of contour and messing up the order. Improve also debugging of MnContour
The computed value of the Minos error was WRONG when parameter+error is over the limit, but the minos point is before the limit.
Thsi can happen for example when computing a limit on a fraction parameter that is bound to be less than 1.
…en g2 is zero When g2 is zero better using an arbitrary value of 1 in the covariance then a very large one, which can be problematic. This commit restores what is so far used in the legacy TMinuit
…s are not present In this case the limit value is zero, so a special treatment is needed to check if a limit is present or not Add also suggestion by Jonas review
After previous commits finding the contour works now in Minuit2
…ed covariance Use precision.Eps() instead of precision.Eps2() for threshold for the lower values for the initial seed covariance matrix
ReadObj returns an owning pointer. Using dynamic_cast and ignoring the "not castable" case can leak memory. See: https://root-forum.cern.ch/t/possible-leak-with-dynamic-cast-and-tkey-readobj/56799
* Correct code highlighting in doxygen * Fix some references to other functions and classes in the reference guide * Add a section that summarizes the relevent implementation details for RooFit AD
In particular, make sure that the brief class description is not too verbose and does not repeat the class name.
For his work on the RooFit Developer Documentation.
While histogram not stored with TGraph2D, it should be append to the pad list of primitives and drawn independently
Otherwise TF1::Save store wrong values, which difficult to use
In some old examples "same" and "sames" draw options for TF1 was used. Currently if "sames" used for TF1 - plain histogram painting is performed which is wrong for the function. Also improve PMC/PLC/PFC handling
1. Fix - proper fit pars display in stats, proper #chi^{2}
2. Fix - several bugs in TFormula parsing
3. Fix - correctly use saved buffer in TF1/TF2
In "classical" TBrowser one want to use normal TCanvas - even if rootrc configured differently. Therefore change gEnv values for the time when canvas is created
* Fix Cocoa GUI for MacOS14 and clang5 * Fix the text editor (Thanks Timur !) (cherry picked from commit 6593d77)
This fixes using the fit2dHist.C when using the global fit (user defined FCN) This PR fixes root-project#13906
