Diagnose fmalloc runtime state

Source: R/fmalloc.R
diagnose_fmalloc_runtime.Rd

Returns diagnostic metadata for an open runtime handle, including lightweight runtime attributes, the current allocation catalog, and a catalog-level summary useful for estimating reclaimable/fragmented payload regions.

Usage

diagnose_fmalloc_runtime(runtime = NULL)

Arguments

runtime

Optional runtime handle returned by open_fmalloc(). If not supplied, the current default runtime is used.

Value

A named list with three components:

  • runtime: runtime metadata such as file path, UUID, mode, catalog counters, live vectors, and reference state;

  • catalog: the full allocation catalog returned by list_fmalloc_allocations();

  • summary: a compact set of computed diagnostics and an explicit compaction status note.

Examples

if (FALSE) { # \dontrun{
rt <- open_fmalloc(tempfile(fileext = ".bin"), mode = "persistent")
x <- create_fmalloc_vector("integer", 4, runtime = rt)
y <- create_fmalloc_vector("logical", 2, runtime = rt)
diagnose_fmalloc_runtime(rt)
cleanup_fmalloc(rt)
} # }
