v0.34.0

8 months ago

DOI

Release v0.34.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

hplot

  • hplot/vgop: a new package to implement JSON serialization of gonum/plot canvases
p := hplot.New()
// ...
err := hplot.Save(p, 10*vg.Centimeter, 20*vg.Centimeter, "plot.json")

  • hplot is now using gonum/[email protected] which has the necessary infrastructure to get nicer timeseries axes. See the provided examples (here) for the hplot.Ticks type.

  • hplot has gained some basic capability to display the legend (a color palette with numbers) of a 2D plot. See the provided example.

  • added a convenience forward function for gonum/plot/plotter.NewLinePoints (as hplot.NewLinePoints)

groot

  • added support for ROOT 6.28/04
  • groot/rjson: a new package to implement JSROOT-compatible JSON serialization of groot's histogram types (rhist.H{1,2}x)
h, err := f.Get("h1d")
raw, err := rjson.Marshal(h)

See the complete example here.

  • groot/rtree is now able to read trees created by Geant4 in multithreaded mode (see here for more details).
  • added support for the "new" TLeafG branch.

v0.33.0

1 year ago

DOI

Release v0.33.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

cmd

  • cmd/hepmc2root: is a new command to automatically convert HepMC2 ASCII files to flat n-tuples ROOT files.
$> hepmc2root -h
hepmc2root converts a HepMC2 ASCII file into a ROOT file and (flat) tree.

Usage: hepmc2root [OPTIONS] hepmc.ascii

Example:

$> hepmc2root ./hepmc.ascii
$> hepmc2root -o out.root -t mytree ./hepmc.ascii

Options:
  -o string
    	path to output ROOT file name (default "out.root")
  -t string
    	name of the output tree (default "tree")

hplot

hplot has been migrated to the new Gio API, and needs Gonum/[email protected].

Slight differences are to be expected in the rendering of plots. With the new Gio version we are using, you may need development headers for Vulkan on Linux. See the installation instructions of Gio for more details: Gio Installation

  • fix a bug in hplot.TiledPlot.Plot(i, j int) where the *hplot.Plot returned by Plot(i,j) was actually the conjugate of what the documentation specified. Now, Plot(i,j) returns the plot as documented.

sliceop

  • introduce a generic sliceop.Resize that can reuse []T capacity
  • introduce generic versions of sliceop.Take and sliceop.Find

Release v0.32.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

This release drops support for Go-1.17 (and earlier) and is the first release with the introduction of a few generics-based APIs.

Thanks to Olivier Mengué (@dolmen) there were a couple of house cleaning changes that have been applied (as part of the CERN+Google Hackathon). Thanks again Olivier.

There has been some work on RNTuple front, but nothing that can be released yet.

v0.31.0

2 years ago

DOI

Release v0.31.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

This release drops support for Go-1.16 (and earlier).

groot

  • bump to ROOT-6.26/00
  • implement a riofs Reader over HTTP(s), instead of downloading the whole file locally

  • streamline C++ templates parsing for STL containers (vector,deque,map,unordered_{,multi}{map,set}, pair, ...)

xrootd

  • improve the read performances 10-fold, using a finer-grained lock to protect session IDs

AOB

That's all for today. Last release we said there would probably be some work on the RNTuple front. We didn't lie, but this didn't happen in the form we thought it would. A surprise is in the works... stay tuned.

Next cycle will probably see some work on the RNTuple front, and that work appear in main.

v0.30.1

2 years ago

DOI

Release v0.30.1 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

fwk

  • updated fwk-app to use the latest gonuts/commander version that provides auto-completion of commands, flags and sub-commands.

groot

  • add support for TBranchObject and TLeafObject
  • add support for TLorentzVector (in root-dump and friends)
  • add support for TNtuple and TNtupleD (in root-dump and friends)

hplot

  • fixed a race in hplot.New where the global variable from gonum/plot was being modified without a critical section. This race appeared when one would create multiple hplot.Plot concurrently.

sliceop

  • improved performances of sliceop/f64s.Take. Do note that sliceop/f64s will probably be rewritten in terms of a generic implementation (and deprecated) once Go-1.18 is generally available.

AOB

That's all for today. Next cycle will probably see some work on the RNTuple front.

v0.29.1

2 years ago

DOI

Release v0.29.1 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes. Most notably, this release uses the new gonum/[email protected] release that fixes a bunch of graphics bugs and performance improvements in plots drawing (PDF, PNG and SVG.)

arrow

We are now using a "vendored" version of github.com/apache/arrow/go without all the flight support, to cut down on the amount of dependencies this was dragging in.

groot

  • groot/{rdict,rtree}: handle groot types mirroring TObject inheritance tree
  • groot/rtree: reduce memory usage in tree-write
  • groot/{riofs,rtree}: handle small/big file thresholds for long-running baskets
  • groot/rhist: handle nil-title in YODA histograms
  • cmd/yoda2root: handle YODA files with a directory structure
  • groot/rhist: implement YODA (un)marshaler for TGraph{,Asymm}{,Errors}
  • groot/rhist: correctly write out TGraph{,Asymm}{,Errors}

hbook

  • hbook: introduce Rand1D. Rand1D represents a 1D distribution created from a hbook.H1D histogram.

hplot

  • hplot: add Label plotter. This plotter allows user to put labels on a plot in "normalized" or "data" coordinates.

xrootd

  • xrootd: fix race in file

AOB

That's all for today. Next cycle will probably see some work on the RNTuple front.
