- complete the version and SSL handshake first, and only then feed
errors into the stream and close connection
- this allows more accurate error handling on both sides
- also the timeOffset error trigger is now more accurate, but requires
more nodes to upgrade
- version command sends list of all participating streams
- biginv sends lists of hosts for all streams the peer wants (plus
immediate children)
- objects will spread to all peers that advertise the associated stream
- please note these are just network subsystem adjustments, streams
aren't actually usable yet
- queues were too short
- some error handling was missing
- remove nonblocking repeats in receive data thread
- singleCleaner shouldn't wait unnecessarily
- sendinv and sendaddress are sometimes being sent to connections that
haven't been established yet, resulting in complaints about stream
mismatch. The error should only be displayed once the connection has
been established and the remote node provides its stream number
- Missing renamed to PendingDownload
- PendingDownload now only retries 3 times rather than 6 to dowload an
object
- Added PendingUpload, replacing invQueueSize
- PendingUpload has both the "len" method (number of objects not
uploaded) as well as "progress" method, which is a float from 0
(nothing done) to 1 (all uploaded) which considers not only objects
but also how many nodes they are uploaded to
- PendingUpload tracks when the object is successfully uploaded to the
remote node instead of just adding an arbitrary time after they have
been send the corresponding "inv"
- Network status tab's "Objects to be synced" shows the sum of
PendingUpload and PendingDownload sizes
- sometimes a node would send an "inv" about an object but then not
provide it when requested. This could be that it expired in the
meantime or it was an attack or a bug. This patch will forget that the
object exists if was requested too many times and not received.
- remember what was requested from which node
- remember if it was received
- re-request object if we haven't received any new object for more than
a minute
- rely on dict quasi-random order instead of an additional shuffle
- request an object once per minute
- stop check after count objects have been found
- tries to avoid calling senddata it it would block receiveDataThread,
allowing fore more asynchronous operation
- request objects in chunks of 100 (CPU performance optimisation)
- moved logic into a Missing singleton
- shouldn't try to download duplicates anymore, only requests a hash
once every 5 minutes and not from the same host
- removed obsoleted variables
- the "Objects to be synced" in the Network tab should now be correct
- removed some checks which aren't necessary anymore in my opinion
- fix missing self in Throttle (thanks landscape.io)
- send buffer to send multiple commands in one TCP packet
- recv/send operation size now based on bandwith limit
- send queue limited to 100 entries
- buffer getdata commands to fill send queue, instead of waiting for the
data packet to arrive first (i.e. allow getdata to work asynchronously)
- SSL handshake would often fail, because verack packet was being sent
at the same time as the do_handshake was executed in a different
thread. This makes it so that do_handshake waits until verack is done
sending.
- also minor modifications in SSLContext initialisation
- fixes errors introduced in the earlier refactoring
- more variables moved to state.py
- path finding functions moved to paths.py
- remembers IPv6 network unreachable (in the future can be used to skip
IPv6 for a while)
- got rid of shared config parser and made it into a singleton
- refactored safeConfigGetBoolean as a method of the config singleton
- refactored safeConfigGet as a method of the config singleton
- moved softwareVersion from shared.py into version.py
- moved some global variables from shared.py into state.py
- moved some protocol-specific functions from shared.py into protocol.py
- minor refactoring, made it into singleton instead of a shared global
variable. This makes it a little bit cleaner and moves the class into
a separate file
- removed duplicate inventory locking
- renamed singleton.py to singleinstance.py (this is the code that
ensures only one instance of PyBitmessage runs at the same time)
- TLS handshake in python is apparently always asynchronous, so it needs
proper handling of SSLWantReadError and SSLWantWriteError
- also adds a timeout and a proper shutdown if handshake fails
- Linux users often don't know that the C PoW is available and complain
it's slow. This will try to build it, and adds availability
notification in the status bar
- also, the updateStatusBar signal now allows emphasised notifications,
which will remain visible for a longer period of time and also
reappear if a status change happened in the meantime
- sometimes SSL connections unnecessarily disconnected on non-fatal
errors. This should fix that. This is however a short term solution
because of migrating to asyncore which has its own error handling
- when you have multiple OpenCL drivers at the same time, e.g. intel and
nvidia, they won't mix leading to crashes. This patch makes it
possible to select which driver to use by listing the available
vendors
- refactored to use the .ui file
- input logic change, address is always optional
- interactive input validation
- runs asynchronously to the main window
- address generator thread can now validate chans in addition to just
adding them
- a user report indicated there is confusion about address error
messages. He/she thought it refers to the sender address, however it
refers to the recipient address. This makes it more clear
- if your time is off by more than an hour, you won't be able to
establish a connection to the network. This patch adds a UI
notification so that the user can understand why he can't connect.
- this has been tested on Windows as well, and has been cleaned up.
There is now a permanent parser thread, and it restarts when the
parsing takes more than 1 second
- Fixes#900
- while 448ceaa74c fixed slow rendering on
windows, there was still a bug where overly long messages caused
freezeing of the hyperlink regexp parser, which appears to happen on
all platforms. Maybe it's a freeze, maybe it just takes too long. This
patch aborts the regexp parser after 1 second and simply displays the
message without hyperlinks being clickable. This doesn't affect HTML
mode because there the links are kept as they are
- Fixes#900
- some messages (e.g. some long messages on Windows, or binary data)
cause an excessive amount of time in rendering the body. This
change is base on a workaround I found at
http://www.qtcentre.org/threads/8188-bug-setLineWrapMode
- most status messages are transient, so they are now only displayed for
10 seconds
- when trying to quit while disconnected or not fully synced, a
three-choice message box now appears: Yes for waiting, No for
closing anyway, and Cancel for aborting the shutdown procedure
- this copyright character has been plaguing pylupdate4 parser and
multiple unsuccessful attempts have been made and then reverted.
Replaced with a HTML entity, hopefully this will finally fix it.
- UI will now display notifications in the status bar if the connection
to the proxy itself is broken. This should give better feedback to
people who are unfamiliar with tor and misconfigured it
- The proxy error handling in the background was slightly improved as
well
- fixes "fast python" (multiprocessing) PoW
- python PoW (both slow and fast) interruptible on *NIX
- signal handler should handle multiple processes and threads correctly
(only tested on Linux)
- popul window asking whether to interrupt PoW when quitting QT GUI
- PoW status in "sent" folder fixes and now also displays broadcast
status which didn't exist before
- Fixes#894
- namecoin connection errors have now severity "info" instead of
"error", because it just confuses peopel who don't have namecoin
configured
- partially addresses #893
- namecoin lookup now also includes name of the record in the recipient
field
- namecoin lookups now support multiple semicolon-separated
recipients like the other recipient-related functions. If there are
multiple recipients, namecoin lookup will look up the last entry on
the line, for example if you have "a; b; c" in the recipient line,
it will lookup "c"
- bitmessage could end up having no known nodes and then it would
freeze. Now it shouldn't freeze, however it can still end up without
known nodes until a restart in some cases (e.g. when suspending the
computer for more then 3 days while BM is running)
- you can now use SMTP to send messages
- uses bmaddr.lan domain
- runs on 127.0.0.8425 if you set "smtpd" to True
- mandatory authentication with smtpdusername and smtpdpassword
- handles old dialog versions better if using curses
- can spawn SMTP delivery thread if configured (only when in daemon
mode)
- daemonized mode now works more like it's properly supposed to on unix
(double fork etc). You may have to adjust your init scripts, when
when using upstart for example you should now use "expect daemon"
- daemon mode now cleanly shuts down when TERM/INT signal is received
- PyBitmessage only used to quit on disk full when running in daemon
mode. When this happened with the QT-GUI, it would end up in a
half-frozen status instead. Quitting is a safer choice
Fixes#572
- helper classes for encoding/decoding messages
- includes both old as well as new extended one (msgpack+zlib)
- the classes are unused yet and are supposed to be for experimenting
- when running a hidden service, the IP of the tor relay was a part of
the verack message. In setups where it's not 127.0.0.1 it may leak
info about network topology
- thanks for an anonymous bug report
- will send the correct combination of hostname and port
- if proxyhostname is a hostname and an IP address, it will now allow
multiple parallel connections for hidden service
- PyBitmessage can now run as a hidden service on Tor
- three new variables in keys.dat: onionhostname, onionport, onionbindip
- you need to manually add a hidden service to tor
