Any enclosures, such as a podcast MP3, will be listed under the entry URL * Made feed timeout compatible with Python versions 2.2 and higher, instead of v2.4 only * Added optional, configurable CSS styling to HTML mail. Set USE_CSS_STYLING=1 in your config.py to enable this. If you want to tweak the look, modify STYLE_SHEET. * Improved empty feed checking * Improved invalid feed messages * Unfortunately, rss2email is no longer compatible with Python v2.1. Two of the most serious lingering issues with rss2email were waiting forever for non-responsive feeds and its inablility to properly handle feeds with international characters. To properly fix these once and for all, rss2email now depends on functionality that was not available until Python v2.2. Hopefully this does not unduly inconvenience anyone that has not yet upgraded to a more current version of Python. v2.58 (2006-05-11) * Total rewrite of email code that should fix encoding problems * Added configurable timeout for nonresponsive feeds * Fixed incorrectly using text summary_detail instead of html content * Fixed bug with deleting feed 0 if no default email was set * Print name of feed that is being deleted v2.57 (2006-04-07) * Integrated Joey Hess's patches o First, a patch that makes delete more reliable, so it no longer allows you to remove the default email address ('feed' 0) and thereby hose your feed file, or 'remove' entries that don't exist without warning; and so it only says IDs have changed when they really have. Originally from http://bugs.debian.org/313101 o Next a patch that avoids a backtrace if there's no email address defined, and outputs a less scary error message. o Next, a simple change to the usage; since the "email" subcommand always needs a parameter, don't mark it as optional. o And, avoid a backtrace if the email subcommand does get run w/o a parameter. o And also avoid backtraces if delete is run w/o a parameter. Also adds support for --help. o Simple change, make a comment match reality (/usr/sbin/sendmail) o This avoids another backtrace, this time if there's no feed file yet. [load()] o Add a handler for the AttributeError exception, which feedparser can throw. Beats crashing.. o Next, four hunks that make it more robust if no default email address is set and feeds are added w/o an email address. This patch originally comes from http://bugs.debian.org/310485 which has some examples. o Finally, this works around a bug in mimify that causes it to add a newline to the subject header if it contains very long words. Details at http://bugs.debian.org/320185. Note that Tatsuya Kinoshita has a larger patch torard the end of that bug report that deals with some other problems in this area, Aaron has seen that patch before and said it "looks pretty reasonable". * add() catches error case on first feed add and no email address is set * Made "emailaddress" consistent param label throughout * Error message improvements * Deleted problematic "if title" line * Deleted space in front of SMTP_USER * Only logs into SMTP server once * Added exception handling around SMTP server connect and login attempt * Broke contributors across multiple lines v2.56 (2006-04-04) * SMTP AUTH support added * Windows support * Fixed bug with HTML in titles rss2email-2.71.orig/feedparser.py0000755000000000000000000051020111530314224015470 0ustar rootroot#!/usr/bin/env python """Universal feed parser Handles RSS 0.9x, RSS 1.0, RSS 2.0, CDF, Atom 0.3, and Atom 1.0 feeds Visit http://feedparser.org/ for the latest version Visit http://feedparser.org/docs/ for the latest documentation Required: Python 2.4 or later Recommended: CJKCodecs and iconv_codec """ __version__ = "5.0.1" __license__ = """Copyright (c) 2002-2008, Mark Pilgrim, All rights reserved.

According to RFC 3023 ('XML Media Types'), if the HTTP Content-Type is application/xml, application/*+xml, application/xml-external-parsed-entity, or application/xml-dtd, the encoding given in the charset parameter of the HTTP Content-Type takes precedence over the encoding given in the XML prefix within the document, and defaults to 'utf-8' if neither are specified. But, if the HTTP Content-Type is text/xml, text/*+xml, or text/xml-external-parsed-entity, the encoding given in the XML prefix within the document is ALWAYS IGNORED and only the encoding given in the charset parameter of the HTTP Content-Type header should be respected, and it defaults to 'us-ascii' if not specified. Furthermore, discussion on the atom-syntax mailing list with the author of RFC 3023 leads me to the conclusion that any document served with a Content-Type of text/* and no charset parameter must be treated as us-ascii. (We now do this.) And also that it must always be flagged as non-well-formed. (We now do this too.) If Content-Type is unspecified (input was local file or non-HTTP source) or unrecognized (server just got it totally wrong), then go by the encoding given in the XML prefix of the document and default to 'iso-8859-1' as per the HTTP specification (RFC 2616). Then, assuming we didn't find a character encoding in the HTTP headers (and the HTTP Content-type allowed us to look in the body), we need to sniff the first few bytes of the XML data and try to determine whether the encoding is ASCII-compatible. Section F of the XML specification shows the way here: http://www.w3.org/TR/REC-xml/#sec-guessing-no-ext-info If the sniffed encoding is not ASCII-compatible, we need to make it ASCII compatible so that we can sniff further into the XML declaration to find the encoding attribute, which will tell us the true encoding. Of course, none of this guarantees that we will be able to parse the feed in the declared character encoding (assuming it was declared correctly, which many are not).

    Getting Started With rss2email

    We highly recommend that you subscribe to the rss2email project feed so you can keep up to date with the latest version, bugfixes and features: http://feeds.feedburner.com/allthingsrss/hJBr

    Instructions for UNIX Users
    Customizing rss2email

    Instructions for Windows Users

    Requirements

    Before you install rss2email, you'll need to make sure that a few things are in place. First, is that a version of Python 2.x installed. Second, determine your outgoing email server's address. That should be all you need.

    Download

    1. Create a new folder
    2. Download the latest rss2email .ZIP file and unzip to the new folder

    Configure

    Edit the config.py file and fill in your outoing email server's details. If your server requires you to login, change "AUTHREQUIRED = 0" to "AUTHREQUIRED = 1" and enter your email username and password.

    Install

    From the command line, change to the folder you created. Now create a new feed database to send updates to your email address:

    r2e new you@yourdomain.com

    Subscribe to some feeds:

    r2e add http://feeds.feedburner.com/allthingsrss/hJBr

    That's the feed to be notified when there's a new version of rss2email. Repeat this for each feed you want to subscribe to.

    When you run rss2email, it emails you about every story it hasn't seen before. But the first time you run it, that will be every story. To avoid this, you can ask rss2email not to send you any stories the first time you run it:

    r2e run --no-send

    Then later, you can ask it to email you new stories:

    r2e run

    If you get an error message "Sender domain must exist", add a line to config.py like this:

    DEFAULT_FROM = rss2email@yoursite.com

    You can make the email address whatever you want, but your mail server requires that the yoursite.com part actually exists.

    Automating rss2email

    More than likely you will want rss2email to run automatically at a regular interval. Under Windows this is can be easily accomplished using the Windows Task Scheduler. This site has a nice tutorial on it. Just select r2e.bat as the program to run. Once you've created the task, double click on it in the task list and change the Run entry so that "run" comes after r2e.bat. For example, if you installed rss2email in the C:\rss2email folder, then you would change the Run entry from "C:\rss2email\r2e.bat" to "C:\rss2email\r2e.bat run".

    Now jump down to the section on customizing rss2email to your needs.

    Upgrading to a new version

    Simply replace all of the files from the .ZIP package to your install directory EXCEPT config.py

    Instructions for UNIX/Linux Users

    Requirements

    Before you install rss2email, you'll need to make sure that a few things are in place. First, is a version of Python 2.x installed. Second, is whether you have sendmail (or a compatible replacement like postfix) installed. If sendmail isn't installed, determine your outgoing email server's address. That should be all you need.

    Download

    A quick way to get rss2email going is using pre-made packages. Here are releases for Debian Linux, Ubuntu Linux and NetBSD.

    If you are unable to use these packages or you want the latest and greatest version, here's what you do:

    Unarchive (probably 'tar -xzf') the rss2email .tar.gz package to [folder where you want rss2email files to live]
    cd [yourfolder]
    chmod +x r2e

    Install

    Create a new feed database with your target email address:

    ./r2e new you@yourdomain.com

    Subscribe to some feeds:

    ./r2e add http://feeds.feedburner.com/allthingsrss/hJBr

    That's the feed to be notified when there's a new version of rss2email. Repeat this for each feed you want to subscribe to.

    When you run rss2email, it emails you about every story it hasn't seen before. But the first time you run it, that will be every story. To avoid this, you can ask rss2email not to send you any stories the first time you run it:

    ./r2e run --no-send

    Then later, you can ask it to email you new stories:

    ./r2e run

    You probably want to set things up so that this command is run repeatedly. (One good way is via a cron job.)

    If you get an error message "Sender domain must exist", add a line to config.py like this:

    DEFAULT_FROM = rss2email@yoursite.com

    You can make the email address whatever you want, but your mail server requires that the yoursite.com part actually exists.

    Upgrading to a new version

    Simply replace all of the files from the .tar.gz package to your install directory EXCEPT config.py

    Customize rss2email

    There are a number of options, described in full at the top of rss2email.py file, to customize the way rss2email behaves. If you want to change something, edit the config.py file. If you're not using rss2email under Windows, you'll have to create this file if it doesn't already exist.

    For example, if you want to receive HTML mail, instead of having entries converted to plain text:

    HTML_MAIL = 1

    To be notified every time a post changes, instead of just when it's first posted:

    TRUST_GUID = 0

    And to make the emails look as if they were sent when the item was posted:

    DATE_HEADER = 1
