Version 0.052 | 2010-04-02 18:10:33Z (Fri, 02 Apr 2010) | d2644fd
Documentation/Sample Code/Test Suite:
* miniswarm tests are given less time before giving up
* 'bad' test (checking if port was opened twice... which seems to be okay
on some systems) has been removed
* Removing t/900_data/950_torrents/951_single.torrent which was used to
test large file support (caused "Out of memory!" errors on smokers
with limited resources)
* This will probably be the last 'stable' version before Net::BitTorrent
is rewritten. Stuff in TODO.pod will be expanded and used as a roadmap

Version 0.050 | 2009-02-13 20:55:16Z (Fri, 13 Feb 2009) | d8d71ee
API Changes/Compatibility Information:
* N::B::Peer objects have their sockets closed and removed *before*
calling any peer_disconnect callbacks.
* Reasons handed to peer_disconnect callbacks are now language agnostic.
Please see Notes section in Net::BitTorrent::Peer for more information.

* (Start of a) Rewrite of t/[...]Peer.t to be more complete and emulate
real-world sessions.
* New demonstration script: /tatoeba/
- Formerly known as /scripts/
* With the addition of Protocol Encryption and the bugfix, I strongly
suggest an upgrade for all users despite the API tweeks.
* Meanwhile...
- Development moved to github:
Version 0.049 | 2009-01-05 17:38:02 -0500 (Mon, 05 Jan 2009)
API Changes/Compatibility Information:
* Net::BitTorrent::Torrent->peers() is now public
* Lists of potential peers are kept by their source (N::B::DHT,
N::B::T::Tracker::HTTP, N::B::T::Tracker::UDP) rather than in
* Resume system (yeah, the thing I added two versions ago) was deprecated
and has been replaced. I thought about it and changing the original
.torrent's metadata is a bad idea so I switched from Rakshasa- to
Resolved Issues/Bug Fixes:
* None
Protocol/Behavioral Changes:
* N::B::T::Tracker::HTTP retry is now 30s on socket error (formerly 5m).
* N::B::Peer objects are disconnected if they don't complete handshake
within 30s.
Documentation/Sample Code/Test Suite:
* New debugging demonstration in /tatoeba/
* New threaded demonstration in /tatoeba/
* New resume demonstration in /tatoeba/
* Various tests temporarily tie STDERR to check as_string() output
* There are several incompatible changes and I've been coding with the
flu this week. Upgrade at your own risk.
N::B could really use your help. Yes, you, the person reading this. If
you're interested, see the "Joining the Project" section in
* Various N::B::Torrent status and internal schedule fixes were made none
of which really effect behavior.
* Meanwhile...
- 2008 ends as it began: uneventfully.
- RIAA drops MediaSentry.

set set defaults, generate a peerid, or create a DHT object.
Protocol/Behavioral Changes:
- None
Documentation/Sample Code/Test Suite:

+ the RIAA stops suing people and will, instead, cancel your 'net service ( and bed your crush.
+ Australia plans to filter BitTorrent. ( ...eventually (
Version 0.042 | 2008-12-04 23:54:43 -0500 (Thu, 04 Dec 2008)
API Changes/Compatibility Information:
- as_string() is now a public method in all classes
Issues Resolved:
- Fixed crash bug (call to legacy method) on failure to write data to disk
Protocol/Behavioral Changes:
- None
Documentation/Sample Code/Test Suite:

- Affected tests updated to reflect as_string() change
- Synopsis in README now matches that of N::B proper
- More silly POD changes for scripts/ ((sigh))
- PAUSE vs. The World (Writable Files)
Version 0.040 | 2008-12-01 23:25:26 -0500 (Mon, 01 Dec 2008)
API changes:
- See the Notes section
- Torrents can now be paused, stopped, and started (alpha code)
- Torrent objects can now be created without a parent client for
informational use (See perldoc Net::BitTorrent::Torrent)
Compatibility Information:
- See the Notes section
- Net::BitTorrent::Session::* is now Net::BitTorrent::Torrent::* thanks to
one very squeaky wheel.
- PeerID spec has changed (stability marker is now 'U'nstable/'S'table
instead of the less obvious and misleading 'S'VN/'C'PAN)
- Torrents aren't automatically checked when loaded.
Internal changes:
- See the Notes section
- UDP trackers are now supported
- DHT actually works
- Fast Ext. is back
- PeerID, DHT node ID, ExtProtocol name, and dist version are all generated
in Net::BitTorrent::Version
Issues resolved:
- No longer floods the system with CLOSE_WAIT sockets which eventually block
the allocation of new sockets
- Since the previous stable release, Net::BitTorrent has been rewritten from
scratch, so yeah, 90% of everything internal has changed, the API was
redesigned as well. I've been pushing dev builds for more than three
months so... yeah.
Version 0.027_001 | Fall 2008
Internal changes:
- Net::BitTorrent is going through a rewrite. Idle hands...
- Don't use this. I'm serious. I'm only uploading it to get some CPAN
testers data.
Version 0.025 | 2008-07-01 23:07:52 -0400 (Tue, 01 Jul 2008)
Internal changes:
- Fix crash bug by re-enabling N::B::S::Peer::_parse_packet_allowed_fast and
N::B::S::Peer::_parse_packet_reject in the packet dispatch table
- Fixed crash bug in Data::Dumper usage in N::B::S::Peer and N::B::DHT
- Fixed non-critical bug in N::B::S::Peer when a connected peer goes
((poof)) in the middle of something.
- Please see the Compatibility Information section from the previous version
- Gah, what a waste of a great version number (0.025)... That's what I get
for not eating my own dog food before shipping it.
- I knew I was forgetting something.
Version 0.024 | 2008-07-01 19:52:15 -0400 (Tue, 01 Jul 2008)
API changes:
- Entire API has changed. See the Compatibility Information below.
- New DHT-related callback: peer_outgoing_port
Internal changes:
- DHT is included with this release. It's really raw code so don't expect
too much.
Compatibility Information:
- I've changed the API to pretty much everything in the distribution with a
depreciation cycle. Bold, yes? So, with so much having changed, putting
a full list of what's changed will be a horrific waste of space. These
are the highlights:
Old Mutator/Accessor New Getter New Setter
maximum_buffer_size get_max_buffer_per_conn set_max_buffer_per_conn
kbps_down get_max_dl_rate set_max_dl_rate
kbps_up get_max_ul_rate set_max_ul_rate
maximum_peers_per_client get_conns_per_client set_conns_per_client
maximum_peers_per_session get_conns_per_session set_conns_per_session
maximum_peers_half_open get_max_halfopen set_max_halfopen
debug_level get_debug_level set_debug_level
maximum_requests_per_peer get_ul_slots_per_session set_ul_slots_per_session
maximum_requests_size get_ul_slot_size get_ul_slot_size
peer_id get_peer_id --NA--
sockport get_sockport --NA--
sockaddr get_sockaddr --NA--
sessions get_sessions --NA--
check get_cached_integrity
verify get_verified_integrity
- The arguments Net::BitTorrent's constructor expects have been changed to
stay in step with the new get/set methods:
Old New
maximum_peers_per_client conns_per_client
maximum_peers_per_session conns_per_session
kbps_down max_dl_rate
kbps_up max_ul_rate
maximum_peers_half_open max_halfopen
maximum_buffer_size max_buffer_per_conn
maximum_requests_size ul_slot_size
maximum_requests_per_peer ul_slots_per_session
- Removed accessors:
- N::B->timeout( [NEWVAL] )
This was the select timeout used in N::B::do_one_loop(). It has
been removed completely in favor of a new optional parameter passed
to N::B::do_one_loop( [TIMEOUT] ) itself.
- I'm sure I'm forgetting something... several somethings, in fact...
- This is an UNSTABLE stable release. There may be calls to old methods
hiding out in a dark corner...
data on the extended test suite, the rewritten API, and the alpha DHT
code. DO NOT INSTALL! Stick with the 0.022 release! As soon as I have a
few reports, I will mark this distribution for deletion from PAUSE.
Version 0.022 | 2008-05-24 10:31:26 -0400 (Sat, 24 May 2008)
API changes:
- Callback system is complete.
+ N::B::S::Tracker was the holdup...
Issues resolved:
- None
Internal changes:
- None
- Upgrade is not required in general but recommended for heavy callback users.
- More POD tweaks.
- Very few changes to scripts/ These are untested changes, btw.
Version 0.020 | 2008-05-22 19:09:05 -0400 (Thu, 22 May 2008)
API changes:
- Experimental N::B::use_unicode() has been removed as wide char filenames
are now handled transparently on Win32.
- New accessor: N::B::Session::name() - see N::B::Session docs
- New methods for alternative event processing:
+ N::B::process_connections() - implement your own select() statement
+ N::B::process_timers() - easily keep internal timers up to date
- Experimental kbps_up and kbps_down methods and N::B::new() parameters have
been renamed properly: kBps_up, kBps_down. Bits. Bytes. It happens.
Issues resolved:
- #1: Line 231 - Check existence of $self->session->files->[$f]->size
+ New .torrent metadata integrity checks during add_session() and piece
+ Log warning and undef returned when N::B::add_session() is handed a
.torrent that does not contain files. (eh, it's a start)
Internal changes:
- Plenty of layout and ideology changes. None of which immediately affect
usability or behavior.
- Extended charset filenames are now handled properly on Win32.
+ Depends on properly encoded utf8 metadata (and the J-Pop fans rejoice)
- (The piece containing) Outgoing blocks are verified for integrity before
being sent to remote peers. Just in case.
- Upgrade is recommended in general.
- Upgrade is strongly recommended for Win32 systems.
- New sample code: scripts/
+ µTorrent WebUI-like demo of alternative event processing.
- To keep N::B from growing too messy and to make co-development attractive,
I'm imposing some coding standards, defining what should be internal,
and deciding how N::B should behave. Between that and the nice weather,
the addition of new features (DHT, UDP trackers, etc.) will be pushed
back a bit. The next few releases will probably be bugfix, API, and
base protocol-behavioral changes.
- Documentation rework in progress.
- What's the cutoff for apologizing for things you said in high school?
Version 0.018 | 2008-04-24 21:14:52 -0400 (Thu, 24 Apr 2008)
API changes:
- Old style set_callback_* syntax is depreciated.
- New methods: kbps_up, kbps_down
- New optional parameters for N::B::new(): kbps_up, kbps_down
Internal changes:
- Fixed crash bug in N::B::S::Peer during endgame
- Upgrade is strongly recommended.
- New feature: Transfer limits to control how much bandwidth N::B is
allowed to use.
- No longer causes taint warnings.
- perl 5.8.1 required. This is based solely on available CPAN
Reporter PASS/FAIL tests and may not be a true representative
Version 0.015 | 2008-04-11 20:00:26 -0400 (Fri, 11 Apr 2008)
- Dup of 0.013 to fix bad M::B dist. Something fishy going on with
the gzip'd file. Some systems (like PAUSE) properly extract
directories and some (like the cpan shell) extract it all into the
base directory causing build failures.
Version 0.013 | 2008-04-11 13:30:36 -0400 (Fri, 11 Apr 2008)
API changes:
- log callbacks now include a message level. See
N::B::Util/"LOG LEVELS".
- removed peer_outgoing_packet callback in favor of more specific,
per-packet-type callbacks.
Internal changes:
- Fixed a bug causing files to be re-opened every time they are read.
- Tons of N::B::S::Peer refactoring. (and much more to do)
- Early Fast Peers and Ext. Protocol testing. (disabled by default)
- Upgrade is recommended.
- This is a documentation update. 100% coverage.
Version 0.008 | 2008-04-01 19:46:20 -0400 (Tue, 01 Apr 2008)
API changes:
- It actually exists
Internal changes:
- See above
