Parallel-Depend-4.07

Changes for version 4.07 - 2009-06-08

  • Fix typo "INT_" in signal name.
  • Two things simplify generation of template schedules: default alias and 'ad_hoc' attribute for the alias.
  • Add single-level attribute for groups to use the group name as an alias for all jobs in the group.
    • This is for staged operations where a set of modules handle, say, the processing of a group of files in one dataset. They all have the same methods for each stage:
      • serialize < Nodes = pass1 > serialize < Names = pass1 > serialize < Division = pass1 > serialize < Delnodes = pass1 > serialize < Merged = pass1 > serialize < Nodes : > serialize < Names : > serialize < Division : > serialize < Delnodes : > serialize < Merged : >
    • becomes just:
      • serialize < alias % pass1 > serialize < Nodes : > serialize < Names : > serialize < Division : > serialize < Delnodes : > serialize < Merged : >
    • The alias is not inherited to avoid accidentally polluting ad_hoc or nested groups. This defines a default alias, allowing for:
      • serialize < alias % pass1 > serialize < Nodes = foo > # explicit alias is foo serialize < Nodes : > # default alias is pass1 serialize < Names : > serialize < Division : > serialize < Delnodes : > serialize < Merged : >
  • The 'ad_hoc' attribute can be assigned to an alias. This simplifies schedules like:
    • serialize < alias % pass1 > serialize < Nodes ~ ad_hoc> serialize < Names ~ ad_hoc> serialize < Division ~ ad_hoc> serialize < Delnodes ~ ad_hoc> serialize < Merged ~ ad_hoc> serialize < Nodes : > # default alias is pass1 serialize < Names : > serialize < Division : > serialize < Delnodes : > serialize < Merged : >
    • to just:
      • serialize < alias % pass1 > serialize < pass1 ~ ad_hoc> serialize < Nodes : > serialize < Names : > serialize < Division : > serialize < Delnodes : > serialize < Merged : >
    • Which leaves each of the jobs (Nodes, Names, etc) handed of as ad_hoc jobs via the managers 'pass1' as $mgr->pass1( $job ).
  • Pushed the alias resolver into P::D::Queue, unalias returns the name and sub, but $que->resolve_alias( $job ) will return just the alias. This is used in merge_attrib to get alias attributes.
  • merge_attrib uses global, alias, and job attributes. this allows for "alias ~ foo" in the schedules.
