    directory next to the trunk, and delete the copies from the branches.
    There's a lot of stuff there (what with all of the documentation of

    r1900 | stevenknight | 2007-05-14 18:48:39 -0500 (Mon, 14 May 2007) | 5 lines

    More specific sconsign signature tests: check for an actual 32-digit-long
    hex string when an MD5 checksum is expected, so we can correctly detect
    test failures if "None" shows up instead.  (This will be used for getting
    avoiding calculating the content signature in 'timestamp' mode.)
  ........
    r1949 | stevenknight | 2007-05-30 22:45:25 -0500 (Wed, 30 May 2007) | 7 lines

    Refactor the get_{csig,timestamp,size}() methods so they use the Memoizer
    pattern, instead of the the NodeInfo object, to cache the results.

    This won't be the final form (we have to reach and stuff a csig value
    in the cache slot to make --implicit-cache work) but it's a step that
    should make it easier to work on other in-progress modifications.
  ........
    r1957 | stevenknight | 2007-06-01 10:18:15 -0500 (Fri, 01 Jun 2007) | 14 lines

    Shift updating a Node's signature/timestamp/size information until after
    the Node has been built (or visited, if it's a leaf Node).  This therefore
    changes the semantics of the .visited() method, so that it's called for
    *every* Node visited, not just leaf Nodes.

    This adds a Taskmaster method for updating a Node's status without
    calling the .built() and .visited() methods, which is used by the
    CleanTask subclass to avoid writing .sconsign info when cleaning (-c).

    Interesting ripple effect in the SConf.py module:  we have to manually
    override the .store_info() method on the Nodes we create, so that they
    don't write out their normal .sconsign information.  The SConf subsystem
    writes out its own by hand.
  ........
    r1962 | stevenknight | 2007-06-01 13:12:24 -0500 (Fri, 01 Jun 2007) | 5 lines

    Fix the ability to catch {IO,OS}Errors during build preparation and
    display the actual Node that triggered the error.  (Which Node actually
    triggers this case, and therefore the displayed error message, changed
    after we delayed content evaluation until *after* a Node is built.)

    Small refactoring:  use {new,get}_ninfo() instead of instantiating
    self.NodeInfo() directly.
  ........
    r1976 | stevenknight | 2007-06-04 16:14:12 -0500 (Mon, 04 Jun 2007) | 5 lines

    Similar to the previous change, call new_binfo() instead of instantiating
    the BuildInfo() type directly.  Change new_binfo() so it doesn't
    automatically attach a NodeInfo object (because sometimes we want the
    existing NodeInfo, and sometimes we want a completely new one).

  ........
    r1979 | stevenknight | 2007-06-05 14:17:32 -0500 (Tue, 05 Jun 2007) | 6 lines

    Delay merging a Node's build information into the .sconsign entry until
    the entry is being written out.  This will allow us to include information
    (such as a content signature) that gets fetched for the first time *after*
    a Node is built.  (The code here isn't the prettiest at the moment, but
    this checkpoints an implementation that passes all the tests.)

    r1980 | stevenknight | 2007-06-06 10:06:56 -0500 (Wed, 06 Jun 2007) | 4 lines

    Refactor to have the store_info() method pull the binfo from
    the Node (instead of having the Node passing it in).
    Add a do_not_store_info() method to override the behavior.

  ........
    r1982 | stevenknight | 2007-06-06 11:48:00 -0500 (Wed, 06 Jun 2007) | 7 lines

    Move responsibility for merging buildinfo entries from Node.FS to the
    SConsign module, through a new Base.store_info() method.  Return the
    existing Base.set_entry() method to actually setting the entry, and use
    the new Base.store_info() method for things that need delayed storage
    and merging.  Adds some commented-out prototype code for delaying
    the buildinfo entry merge until later.

    Better testing for parallel-build exceptions:  re-order the file names
    so that the input files are evaluated before the output files, increasing
    the likelihood of all three being built by simultaneous threads.

  ........
    r1985 | stevenknight | 2007-06-06 23:01:23 -0500 (Wed, 06 Jun 2007) | 11 lines

    Pull the NodeInfo objects out of the BuildInfo object and just deal
    with them as co-equal attributes of a Node.

    .sconsign files now have a place-holder SConsignEntry class that holds a
    Node's separate binfo and ninfo objects.  This will also be more flexible
    if we ever add more information in the future.

    Since this changes the format (but not content) of the .sconsign file
    entries, we will need to double back and figure out how to make the
    transition from pre-BSR .sconsign files before this goes live.

  ........
    r1987 | stevenknight | 2007-06-07 18:59:31 -0500 (Thu, 07 Jun 2007) | 12 lines

    Track the content signature directly in the NodeInfo object, not in the
    _memo dictionary.

    Wipe out the existing NodeInfo after the Node has
    been built so the content signature gets recalculated correctly.

    Change the NodeInfoBase.update() method so that the default behavior is
    to always update the specified fields, not just ones that exist.  This
    was necessary to get Alias and Value Nodes to work with this.

    Remove left-over comments.

    Invert the logic (is_up_to_date => changed) when gathering Configure
    Node states, and eliminate (most) Boolean logic that short-circuits
    some of the tests.  (This area isn't critical, so making sure the code
    is readable is more important than pure performance.)
  ........
    r1990 | stevenknight | 2007-06-09 17:14:32 -0500 (Sat, 09 Jun 2007) | 7 lines

    Refactor the Node.changed() method so it always evaluates every
    dependency, instead of returning early as soon as it finds a difference
    (like a different number of old and new dependencies).  This will be
    necessary to delay evaluation of Node information (content signatures)
    until it's actually needed (instead of evaluating it up front in case
    it's needed later).

    Avoid generating content signatures unless they're actually used:

    Don't automatically create a content signature after a File Node is
    built/visited, and delay the .sconsign merge of the information until
    just before the information will be written.  This means we'll only write
    out information that's actually fetched and used as part of deciding
    whether or not to rebuild any targets.

    Use zip() to collect the children and previous signatures info more
    efficiently when deciding if a node must be rebuilt.  (The comment in
    the previous version of the source code about not using zip() because
    of Python 1.5 name space problems was due to the way the SConfTests.py
    module tried to reset the world's state.)

    Refactor lookup of Node.FS nodes as follows:
    * Completely get rid of _doLookup(), which was old, complicated code
      that implemented a top-down, entry-by-entry search for path names.
    * Use a new FS._lookup() method, which normalizes names to absolute
      paths, with a new RootDir._lookup_abs() method, which handles the
      actual lookup.  We plan to use the latter method for fast(er) internal
      lookups of already-normalized paths.
    * Create a new separate FS.get_root() method, just to avoid clutter
      in the RootDir._lookup_abs() method.

    In the .sconsign file, store the paths to all of the dependencies relative
    to the top-level SConstruct directory, not the target's directory.
    This allows us to be much more efficient when writing the .sconsign file
    (since we can just store the already-computed path) and reading the
    .sconsign file (since we can use the quick, normalized-lookup method to
    translate the string into the correct Node).

   * additional testcase for packaging:
      * building multiple packages from one scons call
      * supplying explicit target names for msi and rpm
      * test the Find*Files() functions

   * modify the package-type option test to not only catch
     the PACKAGETYPE, but also the --package-type alias
     command line argument

   * move FindInstalledFiles to Environment.py and remove
     Find*Files() functions from the packaging module.

   * capitalize the VENDOR tag for msi

   * remove the superfluous packager.py files

   * Add documentation for FindInstalledFiles() and
     FindSourceFiles()

  Handle duplicate fies in a target list:  only decrement the reference
  count once for the target, not once for each time it shows up in the
  list, so dependencies don't "disappear" from the DAG walk because the
  reference count gets decremented past zero.
