Description

  1. Redesign all *shelve-like data bases:
    • add abstract base class
    • implement concrete databases :
      • zipshelve (ZIP/GZIP compression )
      • bz2shelve (BZIP2 compression) in terms of base class
      • lzshelve (LZMA-compression) only for python3
  2. impove timing functions
  3. improve TTree.the_variables
  4. selector via frames: change order of variables in snapshot
  5. improve statistics for selectors
  6. improve a bit printout for TTree/TChain (sorted, type,...)
  7. improve a bit printout for DataFrame (sorted)
  8. generate temporary column names for DataFrame using hash instead of random
    • it allows better debugging (reproducible)
  9. re-enable security key for paralell python servers
  10. Update all tree-collection utilities
    • Files
    • Data
    • Data2
    • DataAndLuimi
  11. Add colorization to progress bars
  12. fix (hope) segfaults for adding new branch to tuple
  13. Improve colorization
  14. make optional use of terminaltables package
  15. add local function to format tables
  16. improve printout of trees and datasets
  17. more improvements in tables&colorization
  18. improve reweighting machinery
  19. add 2D and 3D moments for the historgams
  20. improve 2D histos comparison functions
  21. improve progress bar
  22. fix addition of new brnaches to TTree/TChain and whole IFuncTree machinery
  23. change the names for example-tests
  24. add script to check the dependensies
  25. one more attempt to fix the crash for FuncTH1
    • add_branches - Notifier is not invoked... Invoke it explicitely!
    • FuncTH1::Notify : reset/delete formula instead of Notify...
    • fixes in Notifier
    • few more fixes
    • add a test for add_branches
  26. make a try to polish a bit the Doxygen/Sphinx machinery
  27. PDF.draw_nll : fix bug for the weighted datasets
  28. Update test_tools_reweight2.py
  29. Add Ostap::Math::ChebyshevApproximation
  30. bug fix in add_branch
  31. extend PDF.nll to accept all keywords
  32. unify PDF.nll keywords with pdf.fitTo keywords
  33. tmva & tmva/chopping: fix problem with non-deleted temporary files/directories
  34. cleanup : add concept of "local" trash, to be deleted when CleanUp instance is deleted
  35. mp_pathos & parallel/task: improve the output of the final statistics, add total time and CPU gain due to paralellization
  36. minor fix in TGraphAsymmErrors.transform
  37. add_branch/add_new_branch
    • extend current functionlaity allowing to add several branches at once
  38. Add "clone" methods for all io-databases
  39. Add dump_root module/utility/recipe to allow reading of databases created with "old" ROOT versions, with old version of streamers
  40. add/extend math-function for graphs
  41. remove drawing artifacts for PDF.draw_nll method
  42. Add ROOT.TGraph.remove method
  43. Improve ROOT.TGraph.filter method
  44. Add plotting options for combined_background, combined_signal and combined_components
  45. Extend the signature for Ostap::Math::gauss_pdf/gauss_cdf
  46. Add PSSmear_pdf - smeared version for PhaseSpace-based PDFs
  47. Add signals & backgrounds keywords for Fit1D-constructor
  48. Add 'args' argument to draw-functions
  49. Add possibility for prefilter of data for TMVA/chopping.
  50. Allow TMVA/chopping tools to process RooFit datasets: (converted internally to TTree)
  51. optimize evaluation of polynomials in Ostap::Math
  52. Add Ostap::Math::Clenshaw::term - evaluate the N-th term of the recursive sequence
  53. Add Ostap::Math::barrier_factor - evaluation of Blatt-Weisskopf angular momentum centrifugal form factors for arbitrary angular momenta
  54. Fix but in VE.purity : Thanks to Alexey Dziuba
  55. Improve configuration of canvas&styles
  56. Few fixes in Dalitz, epsecially for drawing it
  57. Add DalitzIntegrator for relatively efficient integration over Dalitz plot
  58. Add true analytical 3-body phase space
  59. Add check for duplicated variable/pdfs names
  60. Add ProgressBar action for DataFrame, now one can display the progress bar during the processing of large frames.
  61. Add context manager to remove/add certain topics to RooMsgService
