Discussion Items

ItemWhoNotes
Action ReviewKTL
  • Qserv dependencies added to stack by Mario.
  • Jacek to make sure copyright statements/licensing are sent to Robyn.
  • RHL to file a ticket about releases of pseudopackages including unnecessary packages.
Action RequestJacek
  • DM-1008 - Getting issue details... STATUS
  • DM-1009 - Getting issue details... STATUS
  • Need better document on how/when to use each log level.
  • Jacek to send instructions to RHL on how to build it.
Action RequestKTL for Dick Shaw
  • Add ds9 to the stack?
  • RHL: We will continue to be able to use ds9 even if we move to something else.
  • Camera team may not have ds9 already.
  • JB: Do as "bring your own" with documentation and a link?
  • DS: Have already done that.
  • FE: Have a better error message if ds9 is not present?
  • DS: Kind of late at that point.  Put in newinstall.sh?
  • Should keep newinstall.sh minimal.
  • Keep in mind this category of optional-but-useful packages.
  • Need a script to check for prerequisites; optional packages could be put in there.
    • FE to create a ticket for this.
Design Deep DiveKTL
  • Level 2 Calibrated Exposure Processing differences from L1
  • Crosstalk correction
  • Master calibration products (including extra ones beyond L1)
  • Source measurement
  • PSF estimation may use entire focal plane, wavefront sensors, history of wavefront data, PSF model built up over time.
DiscussionKTL
  • Items from LSST2014 meeting
  • DS: Warnings about deprecated packages in doxygen and even at build time?
  • RHL: Two situations: where there is a replacement now and where there will be eventually.
  • When we know a package is likely to go away or have its interface change extensively, we should mark the package as such.  Doing it in the package summary page is adequate for now.
DiscussionKTL
  • Package renaming and reorganization
  • JBosch: People should submit strawman proposals for debate.  Also come up with possible relevant issues like SWIG being slower for multiple packages.
  • FE: Want some idea of how repos work with each other; hard with a large number.
  • History: many packages for dependencies and developer interaction.
  • JBosch: Reorganize Python namespaces to make more sense; can be independent of git repos.
  • RHL: Focused proposal for objections might be better.
  • DS: Structure can be helpful explaining how packages relate.
  • FE: git modules are a problem.  Highly hierarchical namespace, but can be in one or a few repos.
  • JBosch: Namespaces that make sense conflict with dependencies.
  • JBecla: Qserv is all in one package.
  • Maximum package size may be set by sharing considerations.
  • FE can provide effort to implement.
  • Should do before moving off gitolite.
  • Aim to have proposal from Jim in the next week or two, have decision by end of September, get everything moved in a week thereafter (if necessary).
