Summary: re.match(), re.MULTILINE and "^" broken
Initial Comment:
The re.match() function does not appear to respect the
re.MULTILINE flag when matching on "^". It does, however,
behave as documented with respect to "$". I've observed this with
Python 2.2.2 and 2.3.3 on Linux, RedHat 9.0. Below is some
sample code and output that illustrates the issue. As illustrated,
re.search() behaves as expected.
$ cat /proc/version
Linux version 2.4.20-28.9psycho (root at sahp5069) (gcc version
3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 SMP Wed Feb 18 07:
08:55 MST 2004
$ python
Python 2.2.2 (#1, Feb 10 2004, 13:57:46)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2

>>>
$ python re_bug.py
Pattern is '^hello world$' with flags = 10
Testing: "hello world
thank you"... match_pass search_pass
Testing: "ahem
hello world"... match_fail search_pass
Testing: "ahem
hello world
thank you"... match_fail search_pass
I would expect the match to work (match_pass and search_pass)
on all of the sample strings.
