<div dir="ltr">Hello all,<div><br></div><div>I have fixed the problem of the hanging-opens on files that are not hddm format but are being attempted to be read as such. David's generic event source registry for JANA allows a person to register any number of classes that can act as event sources, so that an analyzer can take events from any number of different kinds of sources (different hddm types, evio data files, root files, etc.) and it automatically discovers which source class can decode which file by trial and error. This is perfectly reasonable design, and goes along with run-time data type discovery and decoding. Predefined file extensions can serve as hints, but fixed format-filename-suffix associations went out of use with MSDOS and the VAX (anybody remember what these were?).</div>
<div><br></div><div>I have tested the revised code with two evio files that Mark D. shared with me, and the one that used to hang on input (if it were given the .hddm extension) now is immediately rejected as invalid hddm. I also checked in various other trivial revisions to get rid of compiler warnings, which now stick out more than ever, thanks to David's new scons system, which I applaud by the way. BMS, may you RIP. David, no scons for hdds?</div>
