It's strange to be able to close these windows while there is work
in progress.
Also set Qt::WA_DeleteOnClose on both windows to make sure that they
are deleted eventually, no matter what happens.
Lots of people read the Bitcoin Core codebase to learn more about
crypto; better to warn about flaws explicitly so they don't blindly copy
the code for other uses and create broken systems.
Always make a pid file, not only when `-daemon` specified.
This is useful for troubleshooting, for attaching debuggers and loggers
and such.
- Write the pid file only after the datadir lock was acquired
- Don't create or remove a pid file on WIN32, and also don't show the option
- Remove spurious `pchCommand[1] = 1` in CMessageHeader()
- Make sure that pchCommand is zero-padded if length is shorter than
COMMAND_SIZE
- Use strnlen to determine length of pcmCommand in GetCommand
There is no reason to store thousands of orphan transactions;
normally an orphan's parents will either be broadcast or
mined reasonably quickly.
This pull drops the maximum number of orphans from 10,000 down
to 100, and adds a command-line option (-maxorphantx) that is
just like -maxorphanblocks to override the default.
Prevent denial-of-service attacks by banning
peers that send us invalid orphan transactions
and only storing orphan transactions given to
us by a peer while the peer is connected.
Flushing after every line when printing to console is desirable when
running with systemd but setvbuf() has slightly different semantics
on Windows that causes warnings. Just do an explicit fflush() after
each line print to console instead.
Avoids that SOCKS5 negotiation will hold up the shutdown process.
- Sockets can stay in non-blocking mode, no need to switch it on/off
anymore
- Adds a timeout (20 seconds) on SOCK5 negotiation. This should be
enough for even Tor to get a connection to a hidden service, and
avoids blocking the opencon thread indefinitely on a hanging proxy.
Fixes#2954.
