pybitmessage (0.3.4-1) raring; urgency=low
* Switched addr, msg, broadcast, and getpubkey message types
to 8 byte time. Last remaining type is pubkey.
* Added tooltips to show the full subject of messages
* Added Maximum Acceptable Difficulty fields in the settings
* Send out pubkey immediately after generating deterministic
addresses rather than waiting for a request

pybitmessage (0.3.3-1) raring; urgency=low
* Remove inbox item from GUI when using API command trashMessage
* Add missing trailing semicolons to pybitmessage.desktop
* Ensure $(DESTDIR)/usr/bin exists
* Update Makefile to correct sandbox violations when built
via Portage (Gentoo)
* Fix message authentication bug

pybitmessage (0.3.211-1) raring; urgency=low
* Removed multi-core proof of work
as the multiprocessing module does not work well with
pyinstaller's --onefile option.

%changelog
* Sun Jun 30 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.4-1
- Switched addr, msg, broadcast, and getpubkey message types
to 8 byte time. Last remaining type is pubkey.
- Added tooltips to show the full subject of messages
- Added Maximum Acceptable Difficulty fields in the settings
- Send out pubkey immediately after generating deterministic
addresses rather than waiting for a request
* Sat Jun 29 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.3-1
- Remove inbox item from GUI when using API command trashMessage
- Add missing trailing semicolons to pybitmessage.desktop
- Ensure $(DESTDIR)/usr/bin exists
- Update Makefile to correct sandbox violations when built
via Portage (Gentoo)
- Fix message authentication bug
* Fri Jun 28 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.211-1
- Removed multi-core proof of work
as the multiprocessing module does not work well with
pyinstaller's --onefile option.
* Mon Jun 03 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.2-1
- Bugfix: Remove remaining references to the old myapp.trayIcon
- Refactored message status-related code. API function getStatus
now returns one of these strings: notfound, msgqueued,
broadcastqueued, broadcastsent, doingpubkeypow, awaitingpubkey,
doingmsgpow, msgsent, or ackreceived
- Moved proof of work to low-priority multi-threaded child
processes
- Added menu option to delete all trashed messages
- Added inv flooding attack mitigation
- On Linux, when selecting Show Bitmessage, do not maximize
automatically
- Store tray icons in bitmessage_icons_rc.py
* Sat May 25 2013 Jonathan Warren (4096 bits) <jonathan@bitmessage.org> - 0.3.1-1
- Added new API commands: getDeterministicAddress,
addSubscription, deleteSubscription
- TCP Connection timeout for non-fully-established connections
now 20 seconds
- Don't update the time we last communicated with a node unless
the connection is fully established. This will allow us to
forget about active but non-Bitmessage nodes which have made
it into our knownNodes file.
- Prevent incoming connection flooding from crashing
singleListener thread. Client will now only accept one
connection per remote node IP
- Bugfix: Worker thread crashed when doing a POW to send out
a v2 pubkey (bug introduced in 0.3.0)
- Wrap all sock.shutdown functions in error handlers
- Put all 'commit' commands within SQLLocks
- Bugfix: If address book label is blank, Bitmessage wouldn't
show message (bug introduced in 0.3.0)
- Messaging menu item selects the oldest unread message
- Standardize on 'Quit' rather than 'Exit'
- [OSX] Try to seek homebrew installation of OpenSSL
- Prevent multiple instances of the application from running
- Show 'Connected' or 'Connection Lost' indicators
- Use only 9 half-open connections on Windows but 32 for
everyone else
- Added appIndicator (a more functional tray icon) and Ubuntu
Messaging Menu integration
- Changed Debian install directory and run script name based
on Github issue #135
* Tue May 6 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.3.0-1
- Added new API function: getStatus
- Added error-handling around all sock.sendall() functions
in the receiveData thread so that if there is a problem
sending data, the threads will close gracefully
- Abandoned and removed the connectionsCount data structure;
use the connectedHostsList instead because it has proved to be
more accurate than trying to maintain the connectionsCount
- Added daemon mode. All UI code moved into a module and many
shared objects moved into shared.py
- Truncate display of very long messages to avoid freezing the UI
- Added encrypted broadcasts for v3 addresses or v2 addresses
after 2013-05-28 10:00 UTC
- No longer self.sock.close() from within receiveDataThreads,
let the sendDataThreads do it
- Swapped out the v2 announcements subscription address for a v3
announcements subscription address
- Vacuum the messages.dat file once a month: will greatly reduce the file size
- Added a settings table in message.dat
- Implemented v3 addresses:
pubkey messages must now include two var_ints: nonce_trials_per_byte
and extra_bytes, and also be signed. When sending a message to a v3
address, the sender must use these values in calculating its POW or
else the message will not be accepted by the receiver.
- Display a privacy warning when selecting 'Send Broadcast from this address'
- Added gitignore file
- Added code in preparation for a switch from 32-bit time to 64-bit time.
Nodes will now advertise themselves as using protocol version 2.
- Don't necessarily delete entries from the inventory after 2.5 days;
leave pubkeys there for 28 days so that we don't process the same ones
many times throughout a month. This was causing the 'pubkeys processed'
indicator on the 'Network Status' tab to not accurately reflect the
number of truly new addresses on the network.
- Use 32 threads for outgoing connections in order to connect quickly
- Fix typo when calling os.environ in the sys.platform=='darwin' case
- Allow the cancelling of a message which is in the process of being
sent by trashing it then restarting Bitmessage
- Bug fix: can't delete address from address book
* Tue Apr 9 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.2.8-1
- Fixed Ubuntu & OS X issue:
Bitmessage wouldn't receive any objects from peers after restart.
- Inventory flush to disk when exiting program now vastly faster.
- Fixed address generation bug (kept Bitmessage from restarting).
- Improve deserialization of messages
before processing (a 'best practice').
- Change to help Macs find OpenSSL the way Unix systems find it.
- Do not share or accept IPs which are in the private IP ranges.
- Added time-fuzzing
to the embedded time in pubkey and getpubkey messages.
- Added a knownNodes lock
to prevent an exception from sometimes occurring when saving
the data-structure to disk.
- Show unread messages in bold
and do not display new messages automatically.
- Support selecting multiple items
in the inbox, sent box, and address book.
- Use delete key to trash Inbox or Sent messages.
- Display richtext(HTML) messages
from senders in address book or subscriptions (although not
pseudo-mailing-lists; use new right-click option).
- Trim spaces
from the beginning and end of addresses when adding to
address book, subscriptions, and blacklist.
- Improved the display of the time for foreign language users.
* Tue Apr 1 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.2.7-1
- Added debian packaging
- Script to generate debian packages
- SVG icon for Gnome shell, etc
- Source moved int src directory for debian standards compatibility
- Trailing carriage return on COPYING LICENSE and README.md

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in. You must make
# exactly 11 lines for the formatting to be correct. It's also customary to
# leave one space after the ':'.

pybitmessage: data, like the sender and receiver of messages, from passive
pybitmessage: eavesdroppers like those running warrantless wiretapping
pybitmessage: programs.

# time is the time that the pubkey was broadcast on the network same as with every other type of Bitmessage object.
# usedpersonally is set to "yes" if we have used the key
# personally. This keeps us from deleting it because we may want to
# reply to a message in the future. This field is not a bool
# because we may need more flexability in the future and it doesn't

Logging and debuging facility
=============================
Levels:
DEBUG Detailed information, typically of interest only when diagnosing problems.
INFO Confirmation that things are working as expected.
WARNING An indication that something unexpected happened, or indicative of some problem in the
near future (e.g. ‘disk space low’). The software is still working as expected.
ERROR Due to a more serious problem, the software has not been able to perform some function.
CRITICAL A serious error, indicating that the program itself may be unable to continue running.
There are three loggers: `console_only`, `file_only` and `both`.
Use: `from debug import logger` to import this facility into whatever module you wish to log messages from.
Logging is thread-safe so you don't have to worry about locks, just import and log.
