Bug #1295

ROOT browser crashes while trying to read ROOT file made by MAUS (0.5.4)

Description

OS: Scientific Linux 6.2 (64 bit)

I use the following commands to load the ROOT browser:
.L $MAUS_ROOT_DIR/build/libMausCpp.so
TBrowser B

Then, when I open a ROOT file and try to read the data in it (by opening a histogram of it in the browser), I get an error (which I have attached herewith). The version of ROOT that 0.5.4 uses is 5.34. I also tested the file with an older version of MAUS (0.2.4) which has a ROOT version of 5.30, and this is what I found:

- With 0.2.4, ROOT loads fine the files that were created with the same version of MAUS. However, it throws an error when I try to read a file created by the newer version of MAUS.
- With 0.5.4, ROOT cannot read neither the files created by the same version of MAUS, nor the ones created by the older version of MAUS.

However, the problems are only with reading the files with the ROOT browser, as a direct python ROOT script can read the files fine, as far as I know.

#1

Updated by Rogers, Chris almost 10 years ago

Can you please attach an output root file, list of datacards used to generate the output root file and any command line tags you used.

It looks like you are using a version of libMausCpp.so that was not used to generate the input data set, but I would like to check.

#2

Updated by Rogers, Chris almost 10 years ago

Note there is a feature that we incorrectly set up some version number within the data structure - this is the message like

root [2] Warning in <TStreamerInfo::BuildCheck>: 
   The StreamerInfo of class MAUS::KLEvent read from file maus_output.root
   has the same version (=1) as the active class but a different checksum.
   You should update the version to ClassDef(MAUS::KLEvent,2).
   Do not try to write objects with the current class definition,
   the files will not be readable.

Raised as #1296

I tried it again, and I did not get the same warning as quoted, although I did still get an error. I will attach the ROOT file and the error message here.

analyze_data_offline.py was used to generate the ROOT file. I'll attach that as well, just in case. The only command line tags I used were --daq_data_path and --daq_data_file.

What are the outputs of
echo $MAUS_ROOT_DIR $PWD $ROOTSYS
and
ldd $MAUS_ROOT_DIR/build/libMausCpp.so | grep -i root
?

I assume it crashed when you try to access some member -- which one?
There is (at least, was) a bug in ROOT where it will get unhappy when you try to address a nonexistent member.
Can you plot run number?

Strange, this time the browser worked better, and loaded the plots fine, until I got to this one: (though I wasn't able to reproduce it; the error occured in one of the TOF data branches)

Can you try to repeat the problem with a compiled binary (see, for example, bin/examples/load_root_file_cpp). ROOT interactive mode is notoriously crappy/buggy.

I tried the load_root_file example, it made two plots of tof1_digits, and they seem fine. The plots do work, it's just the browser that intermittently decides to crash on every single plot. Just as you said about the interactive mode. (I only use it to find out what is where.)

It may be we are making some subtly wrong call to ROOT wrong somewhere, or it may be that there is a problem in the TBrowser - I just don't know. It is hard to debug as you can see - so fine to use the TBrowser to figure out the tree structure, but as you have seen it is a more robust work flow to use a compiled binary. If you find a problem in a compiled binary then probably we need to dig further.

To quote the MAUS documentation

In general, working through the ROOT command line or ROOT macros is notoriously unreliable and is not supported by the MAUS development team; it is useful as a basic check of data integrity and no more.

I will reject this issue but if you find any further problems feel free to reopen or open a new bug.
