ctags never stops when I try to build a tag file for all python libraries

Question

I used to use ctags to generate a tags file for all installed python libraries by this command:

C:\Windows\System32>ctags -R -f d:\home\vimfiles\python.ctags d:\Python26

But this morning, after I upgraded to Python 2.6.7, that command only generates the following output and never finishes its job. The size of the tags file doesn't change anymore once it reaches about 11MB.

ctags: Warning: ignoring null tag in d:\Python26\Lib\copy.py
ctags: Warning: ignoring null tag in d:\Python26\Lib\pickle.py
ctags: Warning: ignoring null tag in d:\Python26\Lib\site-packages\django\contrib\admin\sites.py

What might cause this problem?

Answer 1

@Gintautas You are genius.

I found ctags was stopped by this file :

D:\Python26\Lib\site-packages\ipython-0.10-py2.6.egg\share\doc\ipython\manual\html\searchindex.js

Exclude it by set the following ctags option could resolve the problem.

--exclude=searchindex.js

I guess it's a bug of ctags.
