# Categorization rules for spacetrace
#
# This file defines the stack frame rules that will categorize
# allocations that spacetrace processes. The format of this file is
#
# <categoryname>
# initial string match for stack frame n
# initial string match for stack frame n+1
# initial string match for stack frame n+2
#
# The key in the matching rule is that for every rule, we provide a
# snippet of the stack frame - contiguous substring matches.
# categorynames and rules substring matches are case sensitive
#
# Predefined Categories
# "All" - All allocations [default]
# "uncategorized" - All allocations that dont match any category

# General principle of categorization:
#
# - Each category, in general, denotes a module or feature.
#
# - We assign each allocation to the module/feature that directly
# caused the allocation irrespective of which higher level module
# caused the allocation. There are very few exceptions usually when
# an allocation belongs both to a feature-category and to a
# module-category.
#
# bookmarks
# Bookmarks. Mainly initialization. Does not include menu cost.
# css
# Cascading style sheets
# dom
# Memory held by DOM.
# font
# All font stuff
# global-history
# html
# html parsing and layout
# images
# All images.
# jar
# jar, zip
# js
# javascript
# necko
# All protocol and uri stuff. All urls created accounted here
# preferences
# Preferences stuff. All js cost for preferences is included here.
## rdf
# Most of the rdf allocations. rdf cost from xul, chromeregistry,
# is assigned to xul.
# xbl
# xbl stuff. Includes js in xbl.
# xpcom
# xpcom, xpt. Allocations for creations of objects are assigned
# onto the respective modules
# xul
# XUL parsing and layout. Includes rdf overhead from xul like
# nsChromeRegistry
#
#
# ===========================================================================
# Leaf rules. We categorize them out first.
# All allocations matching these rules DO belong to the category.
