http:BL / Drupal 7

This "1.0" release follows 6 stable release candidates that have been field tested since July 2011.

Features:

• http:BL lookups for visitor IPs
• Blocking of requests coming from blacklisted IPs
• Database caching, decreasing the number of DNS lookups
• Honeypot link placement on ban page and optionally in footer
• Whitelisting through the httpbl cache table
• Blacklisted IPs banned (added to Drupal blocked_ips table)
• Greylisting: grants the user access if they pass a simple test
• Optional: Checking only when a comment is placed,
  appends a message to blocked comments for easier admin identification,
  and queues the unpublished comment for moderation if the lookup is positive
• Basic statistics on the number of blocked visits
• Optional 3 levels of logging (Error only, Positive Lookups or Verbose - for testing and gaining trust)
• Greylisting threat-level threshold configurable in admin settings.
• Blacklisting threat-level threshold configurable in admin settings.
• Length of time cached visits are held are determined by configurable settings (not hard coded)
• Default Views included (identify blocked and whitelisted IPs with links to their Honeypot profiles)
• Integration with Drupal Help and Permissions

This release candidate adds (for D7):

This release candidate re-fixes #1234174: Http:BL doesn't allow a user with admin-permissions to access Config (requires the original admin user) which was initially fixed in httpbl 7.x-1.0-rc2 but then reintroduced in httpbl 7.x-1.0-rc3, due to a git boo-boo.

This release candidate is based on the 6.x-2.x-dev ("alternate fork") for this project, which has been production field tested for nearly two years. It's also the fork that is used on Drupal.org.

It includes bug fixes and some new features that were first introduced in the Drupal 7 version.

Fixes Included:

http:BL is now Drupal 7 Ready

Features:

This dev release is an alternate fork from 6.x-1.x-dev. It includes bug fixes and some new features that are included in the Drupal 7 release.

Fixes Included:

Development release for Drupal 6.x. The code is greatly cleaned up and request block efficiency should have increased greatly because of optimized hook_boot and hook_init usage. This allows the request to be blocked as early on in the bootstrap as possible. Furthermore the module can leverage the Drupal access table to deny requests to blacklisted users even earlier (just after the database is bootstrapped).

This release adds a lot of bug fixes, PostgreSQL compatibility (thanks to jaydub), an option to check only on comments (thanks to msameer) and (finally) some basic statistics!

Added blacklist caching so that the module makes as few DNS lookups as possible.
