### IMPORTANT ### # This code is released into the public domain. ### RECENT CHANGES ### # 30 Nov 2005: Created, based off of the 12 Nov 2005 version of Pearle Wisebot # 15 Feb 2006: Modifed "retry" to work with any function that signals failure by dying, modified to use a simple exponential backoff formula # Simplified "limit" code, modified to take an optional parameter # Added "config" function as a clean interface to change internal parameters # Modified Wiki-access functions for use with the new "retry" function # Cleanup of boolean config vars to use standard Perl boolean conventions # 28 Feb 2006: Added checkLogin bottleneck, option to allow editing while logged out # Added support for proxy servers # 8 Mar 2006: Added support for getting a user's contributions # Added support for retrieving logs # Separated out some common regex parts into variables # 29 Mar 2006: Added protection against Unicode in URLs # Made thrown exceptions consistent # Sanity-checking on postPage: talkpage without article, userpage or user talkpage without user # 17 May 2005: Improved log retrieval # 12 Jul 2007: Added timestamp to information retrieved from logs # Errors thrown by this package always begin with a three-digit number # 4xx: HTTP client errors # 505: Server error: HTTP version not supported # 509: Server error: Bandwidth exceeded # # 900: Unspecified internal error. # 901: Library not initialized. You didn't call Pearle::init() before calling this function. # 902: Parameter error. You made a function call, but forgot a mandatory parameter, or provided an invalid one. # # 920: Unexpected response. The MediaWiki site returned something unexpected. # 921: Unexpected logout. The MediaWiki site logged us out unexpectedly. # 922: Edit conflict. Someone edited the article while we were. # 923: Deleted article conflict. Someone deleted the article while we were editing. package Pearle; use strict; use warnings; use Time::HiRes; use utf8; use LWP::UserAgent; use HTTP::Cookies; use HTTP::Request::Common qw(POST); use HTML::Entities; # Standard regex parts $Pearle::regex_timestamp = '(\d\d):(\d\d), (\d\d?)
