     1 # Categorization rules for spacetrace

2 #

     3 # This file defines the stack frame rules that will categorize

     4 # allocations that spacetrace processes. The format of this file is

5 #

     6 #       <categoryname>

     7 #       initial string match for stack frame n

     8 #       initial string match for stack frame n+1

     9 #       initial string match for stack frame n+2

    10 #

    11 # The key in the matching rule is that for every rule, we provide a

    12 # snippet of the stack frame - contiguous substring matches.

    13 # categorynames and rules substring matches are case sensitive

    14 #

    15 # Predefined Categories

    16 # "All"           - All allocations [default]

    17 # "uncategorized" - All allocations that don't match any category

    24 # General principle of categorization:

    25 #

    26 # - Each category, in general, denotes a module or feature.

    27 #

    28 # - We assign each allocation to the module/feature that directly

    29 #   caused the allocation irrespective of which higher level module

    30 #   caused the allocation. There are very few exceptions usually when

    31 #   an allocation belongs both to a feature-category and to a

    32 #   module-category.
