================================================================ Dear Bug Team! I don't know what set of changes introduced the problem, but I noticed recently that when I visit a longish Python file it takes a long while for XEmacs to settle down. It quickly scans the entire buffer for syntax highlighting purposes but then it goes into a long cycle of flashing the watch cursor while it thinks about and computes something. I enabled debug-on-quit and killed it the next time that happened. It appeared to be doing some function menu initialization. I reloaded the file (find-alternate-file) and let it complete this time then looked at the Functions menu (which I had never paid any attention to before). It had the docstring from the start of the file listed as the first "function". Hmmm... At any rate, here's what I did to reveal the problem: (add-hook 'find-file-hooks 'fume-setup-buffer) (add-hook 'Manual-mode-hook 'turn-on-fume-mode) Restart XEmacs, then visit a largish Python file. My candidate was the os.py module in my Python sandbox. The Subversion trunk version currently starts with this (indented here to highlight it): r"""OS routines for Mac, NT, or Posix depending on what system we're on. This exports: - all functions from posix, nt, os2, or ce, e.g. unlink, stat, etc. - os.path is one of the modules posixpath, or ntpath - os.name is 'posix', 'nt', 'os2', 'ce' or 'riscos' - os.curdir is a string representing the current directory ('.' or ':') - os.pardir is a string representing the parent directory ('..' or '::') - os.sep is the (or a most common) pathname separator ('/' or ':' or '\\') - os.extsep is the extension separator ('.' or '/') - os.altsep is the alternate pathname separator (None or '/') - os.pathsep is the component separator used in $PATH etc - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n') - os.defpath is the default search path for executables - os.devnull is the file path of the null device ('/dev/null', etc.) Programs that import and use 'os' stand a better chance of being portable between different platforms. Of course, they must then only use functions that are defined by all platforms (e.g., unlink and opendir), and leave all pathname manipulation to os.path (e.g., split and join). """ #' import sys, errno _names = sys.builtin_module_names # Note: more names are added to __all__ later. __all__ = ["altsep", "curdir", "pardir", "sep", "extsep", "pathsep", "linesep", "defpath", "name", "path", "devnull", "SEEK_SET", "SEEK_CUR", "SEEK_END"] I wonder if fume mode gets confused by Python's docstrings. I'm using the just-released version 5.0.0 of python-mode. I checked it into the xemacs-packages CVS repo yesterday, so it should soon be available for everyone (or you can grab it from Launchpad: https://launchpad.net/python-mode -- Skip Montanaro - skip(a)pobox.com - http://smontanaro.dyndns.org/ ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Darwin montanaro-dyndns-org.local 9.2.0 Darwin Kernel Version 9.2.0: Tue Feb 5 16:13:22 PST 2008; root:xnu-1228.3.13~1/RELEASE_I386 i386 ./configure '--prefix=/Users/skip/local' '--with-optimization' '--without-error-checking' 'LDFLAGS=-L/opt/local/lib' 'CPPFLAGS=-I/opt/local/include' '--with-jpeg' XEmacs 21.5-b28 "fuki" configured for `i686-apple-darwin9.2.0'.
