* Repair the broken link to norobots-rfc.txt.
* HTTP response codes >= 500 treated as a failed read rather than as a not
found. Not found means that we can assume the entire site is allowed. A 5xx
server error tells us nothing.
* A successful read() or parse() updates the mtime (which is defined to be "the
time the robots.txt file was last fetched").
* The can_fetch() method returns False unless we've had a read() with a 2xx or
4xx response. This avoids false positives in the case where a user calls
can_fetch() before calling read().
* I don't see any easy way to test this patch without hitting internet
resources that might change or without use of mock objects that wouldn't
provide must reassurance.
needed (better set available in Lib/test/test_robotparser.py). Clean up a
few PEP 8 nits (compound statements on a single line, whitespace around
operators).
- Use substring search, not re search for user-agent and paths.
- Consider * entry last. Unquote, then requote URLs.
- Treat empty Disallow as "allow everything".
Add test cases. Fixes#523041
* restores urllib as the file fetcher (closes bug #132000)
* allows checking URLs with empty paths (closes patches #103511 and 103721)
* properly handle user agents with versions (e.g., SpamMeister/1.5)
* added several more tests
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.
The robotparser.py module currently lives in Tools/webchecker. In
preparation for its migration to Lib, I made the following changes:
* renamed the test() function _test
* corrected the URLs in _test() so they refer to actual documents
* added an "if __name__ == '__main__'" catcher to invoke _test()
when run as a main program
* added doc strings for the two main methods, parse and can_fetch
* replaced usage of regsub and regex with corresponding re code
