commit b880c430e8e69ef90e1ec0840f3b1c92360e9885
Author: Fred Wright <address@hidden>
Date:   Thu Apr 14 19:54:21 2016 -0700

    Fixes cycle_analyzer for Python 3 (as well as other bugs).
    
    It appears that this program hadn't been used in a while, since it had
    bugs unrelated to Python 3.  After fixing some bugs, it's able to run
    successfully on all the test logfiles, except that it chokes on the
    binary data in ac12_binary (due to a newline within the binary data),
    and on the known malformed sentence in triton400.
    
    In order to allow the utility functions in gps.misc to be imported, it
    adds a symlink from devtools/gps to gps.  Due to some weirdness in
    Python 3 imports, there didn't seem to be any other way to make this
    work with uninstalled libraries, and in any case it allows the local
    libraries to take precendence over the system libraries.
    
    TESTED:
    Ran with all six supported Python versions on all daemon logfiles,
    with only the errors noted above.

    Fixes devtools/flocktest for Python 3.
    
    These fixes are applied "mostly blind" due to the inability to run
    this "for real", but they're pretty straightforward.
    
    TESTED:
    Ran -? and (unsuccessful) -c with both Python 2 and Python 3.
    Otherwise untested.

Date:   Thu Apr 14 19:54:19 2016 -0700

    Fixes scons post-cleanup in devtools/sizes.
    
    I'd missed that there were two places doing cleaning.  This applies
    the same fix to the second as was previouly applied to the first.
    
    TESTED:
    Ran and verified that the .sconf_temp directory is no longer left
    around.

commit 3572ff3f090220021894ed02a7b577b5d286a05e
Author: Fred Wright <address@hidden>
Date:   Sat Apr 16 00:01:13 2016 -0700

    Fixes contrib/webgps.py for Python 3.
    
    Since the import fallback hack doesn't work properly in Python 3, this
    gets rid of it and adds a symlink to make the 'gps' package directory
    directly available here (similar to what was done in devtools).  It
    then makes a few minor fixes for Python 3.
    
    The default Python 3 pickle protocol 3 doesn't work in Python 2, but
    protocol 2 doesn't work correctly in this case either, so there
    doesn't seem to be any way to make the tracks file
    backward-compatible.  Thus, it just uses the default protocol and
    punts at load time if the load fails.
    
    This change also fixes the reversed skyview, for consistency with
    pretty much everything else.
    
    There was one case where it crashed with a "dictionary changed size"
    error that appeared to be due to the delete_stale method's deleting a
    dictionary entry while scanning it, which is a no no.  This has also
    been fixed.
    
    Also adds the result files to .gitignore.
    
    TESTED:
    Ran with both Python 2 and Python 3.  This included one run of over
    three hours without any more crashes.

commit e32a8f856b810486ea260f450611a6e331692f83

    Adds a tool for cleaning up after Python uninstall bug.
    
    Since the just-fixed SConstruct bug could have left empty Python
    package directories lying around in multiple Python installs,
    this provides a tool for cleaning them all up.  It applies to
    every non-text python* file in the command PATH, and removes
    any empty 'gps' package directories.  Nonempty directories are not
    removed.
    
    TESTED:
    Verified that directories left over by the uncorrected uninstall were
    removed, and that nonempty directories weren't.  Tested with both
    Python 2 and Python 3.

    Fixes gps.gps.gps iterator for Python 3.
    
    Python 3 renames the iterator next() method to __next__().  Without
    the new name, attempting to use the object as an iterator doesn't
    work.  This didn't surface until trying webgps.py.
    
    For compatibility with both Python 2 and Python 3, both names need to
    be provided.  This change renames the existing method to conformto
    Python 3 naming, and then adds a wrapper to provide the old name for
    Python 2.
    
    TESTED:
    Ran webgps.py (with uncommitted fixes) with both Python 2 and Python
    3.

commit 0631b9e3a24a9215f3d10d9434bf42e0c50c2408

    Fixes uninstall to remove Python package directory.
    
    Uninstall was removing the contents of the Python package directory,
    but not the directory itself.  There's an asymmetry where an
    unmentioned directory is created automatically when needed, but not
    removed when it's rendered empty.
    
    In Python 2, this is a fairly harmless error, albeit slightly unclean,
    since directories lacking an __init__.py file are ignored by the
    import logic.  But in Python 3, which allows the init file to be
    omitted, leaving the empty directory around causes "import gps" to
    apparently succeed and create an empty "namespace" module.  Not only
    does this confuse programs attempting to detect import failures, but
    it also prevents a future import from working even after adjusting
    sys.path, since reimporting an already imported module is a NOP.
    
    The fix is simply to include the directory explicitly in the list for
    python_install.  This has no actual effect on the install, but
    includes the directory in the uninstall.
    
    TESTED:
    Ran install/uninstall and verified that the directory is now removed
    by the uninstall.
