# 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 don't 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
# layout
#       reflow, frames, line, view
# 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. 
#
# wallet
#       Form cache.
#
# 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.
