When using the following re to extract all objects from a
PDF file, I get a maximum recursion limit exceeded error.
Attached is a pdf file that will reproduce the error.
If I do import pre as re, it works fine.
platform is Win2k, Python 2.2.1 build #34
#######
import re
GETOBJECT = re.compile(r'\d+\s+\d+\s+obj.+?endobj',
re.I|re.S|re.M)
pdf = open('userguide.pdf', 'rb').read()
all = GETOBJECT.findall(pdf)
print len(all)

Logged In: YES user_id=352797 The max recursion limit problem in the re module is well-known. Until this limitation in the implementation is removed, to work around it check http://www.python.org/dev/doc/devel/lib/module-re.html http://python/org/sf/493252 |

Logged In: YES user_id=357491 Closing this since hitting the recursion limit is not a bug. |

Logged In: YES user_id=7887 As Gary Herron correctly pointed me out, this was fixed in 2.3 with the introduction of a new opcode to handle single character non-greedy matching. This won't be fixed in 2.2.3, but hopefully will be backported to 2.2.4 together with other regular expression fixes. |
