v1.6.1

Go 1.27 compatibility fix: caliper now requires x/tools v0.51.0. On v1.6.0, a program reaching a method with type parameters panicked the call graph, and the export-data load ended the process on go-plus 1.27.2.

Fixed

  • The call graph no longer panics on a method with type parameters
    (#40). Go 1.27 allows methods with type parameters of their own, and
    the standard library has one, math/rand/v2's (*Rand).N. Any
    program that reached such a method made BuildInterProceduralContext
    panic with the type parameter's name (panic: Int) inside x/tools'
    Program.RuntimeTypes. caliper now requires x/tools v0.51.0, which
    skips those methods there; calls to them are edges in the graph.

  • The export-data load works on go-plus 1.27.2. With x/tools
    v0.44.0, DepsFromExportData on a module importing the standard
    library ended the process with internal error: package "fmt" without types was imported from .... The x/tools v0.51.0 bump above fixes it.

  • A panic during call graph construction is returned as an error.
    BuildInterProceduralContext used to let it end the process; the
    next input x/tools cannot handle now fails the build of the context
    instead.
