- 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
- bitmsghash should now build and run on BSD (thanks for
FreeBSD/Dragonfly maintainers for assistance)
- if it cannot detect the number of cores, will default to one thread
(previously it broke)
Two file merge conflicts, __init__.py and upnp.py, were not resolved
correctly by the automatic resolving (probably because the affected code
was written by other people and I merged them into mailchuck fork). This
changes it to the same code that is in the mailchuck fork)
On Windows, the encoding was always the default windows encoding and
didn't change when you use a language in BM that required a different
encoding. This affected mainly date & time in the received column and
the startup info on the network status tab.
The plural/paucal form support was not compatible with pylupdate4, it
didn't correctly parse the 3-argument calls to translate.
This fixes it, and updates the sources accordingly.
Some parts of strings did not use the proper locale. For example, date
and time strings was always output with the US locale. This fixes it.
There are still some cases where localisation is not implemented, and
could be changed from str(string) to locale.str(string).
- it shows that it needs to wait for PoW to finish
- it waits a bit for new objects to be distributed
- it displays a better progress indicator in the status bar
Previously, people who don't understand how PyBitmessage works sometimes
shut it down immediately after they wrote a message. This would have
caused the message to be stuck in the queue locally and not sent. Now,
it will indicate that the PoW still needs to work, and it will wait a
bit longer so that the message can spread. It's not a completely correct
approach, because it does not know whether the message was really
retrieved after the "inv" notification was sent.
Now only in status bar and no more popup window.
Previously, it only showed once until a restart, but now it shows every
time it detects a new version online. Since it does not show a popup
window it's not a big deal.
The language combo box is generated dynamically from the list of
available translations in the translations directory. This allows the
users to add their own translations without having to change the code.
Added a RetranslateMixin. Since PyQT does not support automated language
changes of UI files (like the C++ QT does), this implements something
similar. It assumes that the UI file has the same name as the class, but
lowercase.
Added RetraslateMixin to the new blacklist and networkstatus interfaces.
- UPnP handles errors better
- it tries to bind external interface (previously sometimes it searched
on 127.0.0.1 resulting in no routers being detected)
The quick navigation key disrupted keybindings with keyboard modifiers,
like Ctrl-C for copy. This restricts the quick navigation only where no
keyboard modifiers are active.
Fixes#184
- delete key now works when message body is focused as well
- N for next message (down)
- P for previous message (up)
- R for reply
- C for compose
- F for find
- Find is now dynamic if the search text is least 3 characters long
Fixes Bitmessage#655
Addresses #155
Rows are deleted from a message list in multiple places, and this is an
attempt to refactor it so that it is done in one function. It's not used
anywhere yet.
MessageView does not currently load external resources (QTextBrowser by
default interprets all external resources as local file names and tries
to load them like that. This can, in the future, be implemented. For
example, if SOCKS (Tor) is used, the resource could be loaded through
the SOCKS too.
This commit is a skeleton for it that does not actually do anything and
can be filled with an implementation that does the loading.
Email addresses and URIs are now clickable when viewing a message in
plain text mode. Clicking an email address moves to the Send tab, while
clicking an URI has the same result as clicking an URI in html mode, it
will ask for confirmation before opening it in external handler.
HTML parser wasn't correctly handling img tags.
Now it also by defaults disabled external schemas to prevent
deanonymisation (even though the renderer actually doesn't support
external schemas at the moment)
Addresses #178
Attackers injected node addresses with port 0 into the network. Port 0
is unusable on many OSes and can't be listened on. PyBitmessage won't
accept nodes that have port 0 anymore.
- postpone initial sleep until the first getdata is received
- also sleep when received a getdata request for an object that hasn't
been advertised to the other node yet
There was a report that by quickly asking a large number of nodes if
they have an ACK object (which the attacker knows but it is injected
into the network by the recipient of the message), it can estimate how
an object propagates through the network, and eventually pinpoint an
originating IP address of the injection, i.e. the IP address of the
message recipient.
This patch mitigates against it by stalling when asked for a nonexisting
object (so that the attacker can't spam requests), and also upon
connection before sending its own inventory list (so that reconnecting
won't help the attacker). It estimates how long a short message takes to
propagate through the network based on how many nodes are in a stream
and bases the stalling time on that. Currently that is about 15 seconds.
Initial connection delay takes into account the time that already passed
since the connection was established.
This basically gives the attacker one shot per a combination of his own
nodes and the nodes he can connect to, and thus makes the attack much
more difficult to succeed.
Editing of blacklist labels affected the rerendering, because it emits
the changed signal too, and it caused an exception because the address
field was missing at that time. This works around both.
In some situations, it's not necessary to send an ACK. For example, when
the sender is blacklisted, when the message has no content, or when the
address has ACK sending disabled.
Also it's not necessary to rebroadcast empty messages into a mailing
list.
When advertising nodes and when establishing connections, private IP
range checks were not done. This could cause private IPs to be
advertised across the network. Also, some of the checks weren't
IPv6-aware.
Fixes Bitmessage#768
If you change, add or remove an item in a treewidget or addressbook,
messagelists will now autoupdate labels, and sender comboboxes will also
update if applicable.
Fixes#69
Message compose sometimes misinterpreted quoted message as HTML, causing
rendering screwups. Since we don't support HTML composing, we will treat
all quoted messages as plain text.
Zooming in message body view / compose works in single steps
irrespective of wheel sensitivity, and info about zoom level is
displayed in percent rather than font pixel size.
if singleWorker crashed, the thread couldn't be joined. This both makes
it so that it doesn't crash, as well as reorders the shutdown sequence
so that it is less likely to be triggered.
Fixes Bitmessage#549
- it didn't shutdown correctly
- it didn't handle exception correctly (however, if I understand
correctly, this will never be triggered if using blocking get, so it
doesn't affect PyBitmessage)
- flushing size check changed from 1 to 0 (I don't know why it was 1)
Flood mitigation was done both in the ObjectProcessorQueue as well as
receiveData threads. This patch removes the mitigation in receiveData
threads and cleans up the one in the ObjectProcessorQueue
- subject on replies was not parsed correctly (or should I say was
parsed more than necessary)
- unicode can handle invalid characters without needing a special
function
Fixes#164
The previous commit broke places where UserData was read from the
mesagelist line, because it's now a string rather than a QVariant. This
actually simplifies things.
On OSX and linux, the tray icon now raises window.
Starting a new instance should raise the window too, but it may not work
on linux (on my Ubuntu it just flashes the icon)
Fixes Bitmessage#743
Items like dialog box buttons were not localised. This loads the default
qt localisation, and also unloads the old localisation on locale change.
Still needs to be adjusted for frozen.
Addresses Bitmessage#737
Message will render as user is scrolling down. This prevents interface
freezes on long messages (such as inline img in text mode). Fixes
Bitmessage##366
Also a minor fix in text mode rendering.
If attempting to send to an email address from an unregistered
account, auto-send registration to mailchuck.
Use label if possible, otherwise random 12 characater address
Fixes#131
- addressGenerator got stuck (introduced recently when cleaning up
shutdown
- do not put addresses into API return queue if API is inactive
- improve translation
