Description

Basically, a dynamic slot's Name is "slotX.Y@Machine". This is displayed by condor_status and can be used in constraints. When using STARTD_SLOT_ATTRS, other slots on a Startd get attributes of the form slotX.Y_Attr. This is a problem because attribute names should not include a period (.), and expressions referencing slotX.Y_Attr -> ERROR. It is possible to replace the . with a _ before sharing Attr, but that will create a special case and users will need to know the displayed name of the slot is not the same as the name used in policy. To fix this problem and avoid special casing, a dynamic slot's name should use a _ instead of the .. It does not appear possible to quote slotX.Y_Attr in policy expressions, as new classad grammar suggests. Dynamic slot names changed from slotX.Y to slotX_y in condor 7.4.2-0.3 Reproduced on: condor-7.4.1-0.7.1.el5 condor_status | grep slot slot1.1 LINUX X86_64 Claimed Busy 0.000 1 0+00:00:27 slot1 LINUX X86_64 Unclaimed Idle 0.030 116 0+00:00:28 Verfied on all platforms with:
