- track pending hashId more accurately
- add timeout and a cleanup so that the download queues don't
get stuck and memory is freed
- randomise download order (only works for inv commands with
more than 1 entry)
- replace PendingDownload singleton dict with a Queue
- total memory and CPU requirements should be reduced
- get rid of somObjectsOfWhichThisRemoteNodeIsAlearedyAware. It has very
little practicle effect and only uses memory
- if too many nodes, only delete oldest nodes in bootstrap provider
mode, in normal mode ignore new nodes as it used to before
- in bootstrap provider mode, penalise nodes announced by others by 1
day instead of 3 hours
- version command struct for faster unpacking
- increase read buffer to 2MB to allow a full command to fit
- initial bitmessage protocol class (WIP)
- error handling
- remove duplicate method
- finished proxy design
- socks4a and socks5 implemented
- authentication not tested
- resolver for both socks4a and socks5
- http client example using the proxy
- if knownNodes grows to 20000, instead of ignoring new nodes, forget
the 1000 oldest ones
- drop connection after sendaddr if too many connections, even if it's
an outbound one
- if maximum total connections are lower than maximum outbound
connections, active bootstrap provider mode
- in this mode, check all addresses received before announcing them
- so basically it only annouces those addresses it successfully
connected to
- I can't get the dynamic loading to work on OSX in frozen mode
- I think that if someone wants to build a frozen executable with custom
messagetypes modules, he can edit the file
- so now it lists the existing types manually (for frozen mode only)
- maxtotalconnections = maximum number of total full connections
(incoming + outgoing) the node will allow. Default 200 as it was.
- maxbootstrapconnections = number of additional (to total) connection
that will act in bootstrap mode, closing after sending the list of
addresses. Default 20 as it was.
- maxaddrperstreamsend = initial address list maximum size, per
participating stream. Default 500. Child streams get half. The
response is chunked into pieces of max. 1000 addresses as that's the
protocol limit.
- on OpenBSD, you can't have a socket that supports both IPv4 and IPv6.
This allows handling for this error, and then it will try IPv4 only,
just like for other similar errors.
- there were reports of errors in FreeBSD (I could only reproduce some)
and Gentoo without IPv4 support (I don't have a VM for testing ready)
- adds an exception handler for double task_done in case sender thread
has to close prematurely (I saw this triggered on FreeBSD 11)
- listening socket opening error handler was broken (triggered if you
can't open a socket with both IPv4 and IPv6 support)
- error handler for socket.accept. Reported on FreeBSD 10.3
- fixes#854
- TTL to chans shouldn't be too low so the UI gives a feedback
- warning when sending wouldn either require a lot of refactoring or
wouldn't have good usability
- don't do subprocess in SafeHTMLParser, it doesn't work in frozen mode
and an attempt to fix it would take too much refactoring and I'm not
even sure it would work
- instead, make it handle broken unicode correctly
- I think the previous reports of freezes were caused by trying to
interpret data as unicode, causing a crash
- it does about 1MB/s on my machine, so a timeout is not a big problem
- spec file for pyinstaller detects architecture (32 or 64bit)
- spec file uses os.path.join
- spec file creates and adds the list of messagetypes
- added MinGW/MSyS support in Makefile
- separate Makefile.msvc for MCVC
- bitmsghash.cpp minor adjustments to build also on MSVC/MinGW
- if frozen mode, messagetypes loads the list of files from a text file
generated during archive building rather than from a directory
- separate Makefile for BSD make
- auto-compile will detect BSD and pass the correct parameters to make
- C PoW builds on OpenBSD and detects number of cores
- "new" folder consistently appears in chans and "All accounts"
- "Sent" message list sorting fix
- When editing a label, keys.dat is saved and the lineEdit completer
is updated
- addressbook is updated when adding/deleting a new chan
- saveKnownNodes replaced the repeated pickle.dump
- with knownNodesLock instead of acquire/release
- outgoingSynSender had an unnecessary loop during shutdown causing
excessive CPU usage / GUI freezing
- networkDefaultProofOfWorkNonceTrialsPerByte and
networkDefaultPayloadLengthExtraBytes cyclic import fix
- PyBitmessage should launch now when there's no keys.dat
- rearranged code to reduce cyclic dependencies
- doCleanShutdown is separated in shutdown.py
- shared queues are separated in queues.py
- some default values were moved to defaults.py
- knownnodes partially moved to knownnodes.py
- 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
