Currently we use a fixed buffer of 250000 bytes to request
HKEY_PERFORMANCE_DATA. In many cases this is not enough, causing the
entropy collection to be skipped.
Use a loop that grows the buffer as specified in the RegQueryValueEx
documentation:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724911%28v=vs.85%29.aspx
(as the size of the performance data can differ for every call, the
normal solution of requesting the size then allocating that can't work)
Two changes:
First removes a unit test that fails in my development environment
(OSX, compiled -g3 with clang).
sipa says that's not terribly surprising; the CMutableTransaction change
makes signing a little more expensive but verification quicker. The unit
test timed sign+verify-uncached versus verify-cached-five-times.
He also says the test will be invalid when libsec256kp1 is integrated
(because validation is super-optimized over signing).
core.h change fixes a compiler warning (clang -Wall : CMutableTransaction defined
as struct, declared as class in script.h).
75c82d4 Move coins.cpp and keystore.cpp to libbitcoin_common (Wladimir J. van der Laan)
84ce18c Remove unnecessary dependencies for bitcoin-cli (Wladimir J. van der Laan)
14f888c Move network-time related functions to timedata.cpp/h (Wladimir J. van der Laan)
This commit removes all the unnecessary dependencies (key, core,
netbase, sync, ...) from bitcoin-cli.
To do this it shards the chain parameters into BaseParams, which
contains just the RPC port and data directory (as used by utils and
bitcoin-cli) and Params, with the rest.
Relax the AreInputsStandard() tests for P2SH transactions --
allow any Script in a P2SH transaction to be relayed/mined,
as long as it has 15 or fewer signature operations.
Rationale: https://gist.github.com/gavinandresen/88be40c141bc67acb247
I don't have an easy way to test this, but the code changes are
straightforward and I've updated the AreInputsStandard unit tests.
bitcoin-config.h moved, but the old file is likely to still exist when
reconfiguring or switching branches. This would've caused files to not rebuild
correctly, and other strange problems.
Make the path explicit so that the old one cannot be found.
Core libs use config/bitcoin-config.h.
Libs (like crypto) which don't want access to bitcoin's headers continue
to use -Iconfig and #include bitcoin-config.h.
This avoids a race condition in which the connection was
made but the version handshake is not completed yet. In that
case transactions won't be broadcasted to a peer yet, and
the nodes will wait forever for their mempools to sync.
`&vch[vch.size()]` and even `&vch[0]` on vectors can cause assertion
errors with VC in debug mode. This is the problem mentioned in #4239.
The deeper problem with this is that we rely on undefined behavior.
- Add `begin_ptr` and `end_ptr` functions that get the beginning and end
pointer of vector in a reliable way that copes with empty vectors and
doesn't reference outside the vector
(see https://stackoverflow.com/questions/1339470/how-to-get-the-address-of-the-stdvector-buffer-start-most-elegantly/1339767#1339767).
- Add a convenience constructor to CFlatData that wraps a vector.
I added `begin_ptr` and `end_ptr` as separate functions as I imagine
they will be useful in more places.
