- SO_NOSIGPIPE isn't available on WIN32 so merge the 2 non-WIN32 blocks
- use predefined names from header for IPV6_PROTECTION_LEVEL and
PROTECTION_LEVEL_UNRESTRICTED
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).
- New status bar control shows the current Unit of Display.
When clicked (left,or right button) it shows a context menu
that allows the user to switch the current Unit of Display (BTC, mBTC, uBTC)
- Recent Requests and Transaction Table headers are now updated when
unit of display is changed, because their "Amount" column now displays the
current unit of display.
- Takes care of issue #3970 Units in transaction export csv file.
- Small refactors for reusability.
- Demo Video https://www.youtube.com/watch?v=wwcr0Yh68go&list=UUG3jF2hgofmLWP0tRPisQAQ
- changes after Diapolo's feedback. Have not been able to build after last pool, issues with boost on MacOSX, will test on Ubuntu these changes.
- removed return statement on switch
- renamed onDisplayUnitsChanged(int) to updateDisplayUnit(int)
- now getAmountColumnTitle(int unit) takes a simple unit parameter. moved to BitcoinUnits.
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.
`&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.

Fixes#4352.
As it says on the tin. It was deprecated in version 0.9, and
at some point it should be removed.
Removes the dependency of bitcoind on libbitcoin-cli.a. Move
some functions that used to be shared but are now only used in
bitcoin-cli.cpp to that file.
After this change, an error is printed (and exit code 1 is returned)
when the user tries to send RPC commands using bitcoind.

Also make it that `-help` can be used to display the help (as well as
existing `--help`). Up to now, `-help` was the only option that didn't

Important: This makes it obvious, that we need to re-think the
settings/options handling, as GUI settings are processed before
any parameter-interaction (which is mostly important for network
stuff) in AppInit2()!
The rcc tool is quirky and only honors files in the same directory as the qrc.
When doing an out-of-tree build (as 'make distcheck' does), the generated
translation files end up in a different path, so rcc can't find them.
Split them up so that rcc is run twice: once for static source files and once
for generated files.

New RPC methods: return an estimate of the fee (or priority) a
transaction needs to be likely to confirm in a given number of
blocks.
Mike Hearn created the first version of this method for estimating fees.
It works as follows:
For transactions that took 1 to N (I picked N=25) blocks to confirm,
keep N buckets with at most 100 entries in each recording the
fees-per-kilobyte paid by those transactions.
(separate buckets are kept for transactions that confirmed because
they are high-priority)
The buckets are filled as blocks are found, and are saved/restored
in a new fee_estiamtes.dat file in the data directory.
A few variations on Mike's initial scheme:
To estimate the fee needed for a transaction to confirm in X buckets,
all of the samples in all of the buckets are used and a median of
all of the data is used to make the estimate. For example, imagine
25 buckets each containing the full 100 entries. Those 2,500 samples
are sorted, and the estimate of the fee needed to confirm in the very
next block is the 50'th-highest-fee-entry in that sorted list; the
estimate of the fee needed to confirm in the next two blocks is the
150'th-highest-fee-entry, etc.
That algorithm has the nice property that estimates of how much fee
you need to pay to get confirmed in block N will always be greater
than or equal to the estimate for block N+1. It would clearly be wrong
to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay
12 uBTC and it will take LONGER".
A single block will not contribute more than 10 entries to any one
bucket, so a single miner and a large block cannot overwhelm
the estimates.
Use CFeeRate instead of an int64_t for quantities that are
fee-per-size.
Helps prevent unit-conversion mismatches between the wallet,
relaying, and mining code.
Now that the build is non-recursive, adding to AM_CPPFLAGS means adding to
_all_ cppflags.
Logical groups of includes have been added instead, and are used individually
by various targets.
- Some file generation was still noisy, silence it.
- AM_V_GEN is used rather than @ so that 'make V=1' works as intended
- Cut down on file copies and moves when using sed, use pipes instead
- Avoid the use of top_ and abs_ dirs where possible
Build logic moves from individual Makefile.am's to include files, which
the main src/Makefile.am includes. This avoids having to manage a gigantic
single Makefile.
TODO: Move the rules from the old Makefile.include to where they actually
belong and nuke the old file.
Should be merged after pull request #4281

three places that are fixed by pull request #4281.
Previously if bitcoind is linked with an OpenSSL which is compiled
without EC support, this is seen as an assertion failure "pKey !=
NULL" at key.cpp:134, which occurs after several seconds. It is an
esoteric piece of knowledge to interpret this as "oops, I linked
with the wrong OpenSSL", and because of the delay it may not even
be noticed.
The new output is
: OpenSSL appears to lack support for elliptic curve cryptography. For
more information, visit
https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries
: Initialization sanity check failed. Bitcoin Core is shutting down.
which occurs immediately after attempted startup.
This also blocks in an InitSanityCheck() function which currently only
checks for EC support but should eventually do more. See #4081.

Fixes#4156.
The problem is that the boost::asio::io_service destructor
waits for the acceptors to finish (on windows, and boost 1.55).
Fix this by keeping track of the acceptors and cancelling them before
stopping the event loops.
Make sure conn object always gets cleaned up by using a
`boost::shared_ptr`.
This makes valgrind happy - before this commit, one connection object
always leaked at shutdown, as well as can avoid other leaks, when
for example an exception happens.
Also add an explicit Close() to the !ClientAllowed path to make it similar
to the normal path (I'm not sure whether it is needed, but it
can't hurt).
According to the [boost::asio documentation](http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/reference/basic_socket_acceptor/async_accept/overload2.html),
the function signature of the handler must be:
void handler(
const boost::system::error_code& error // Result of operation.
);
We were binding *all* the arguments, instead of all but the error,
resulting in nullary function that never got the error. Fix this
by adding an input argument substitution.

`-rpcallowip` currently has a wacky wildcard-based format. After this
commit it will accept the more standard format, for example:
- Ranges with netmask 127.0.0.0/255.255.255.0, ::/0
- Ranges with cidr 12.3.4.5/24, 12:34:56:78:9a:bc:de:00/112
- Loose IPs ::1, 127.0.0.1
Trying to use the old *?-based format will result in an error message at
launch.
None of the current integer parsing functions in util
check whether the result is valid and fits in the range
of the type. This is required for less sloppy error reporting.

Github-Pull: #4106
redeemScripts >520bytes can't be spent due to the
MAX_SCRIPT_ELEMENT_SIZE limit; previously the addmultisigaddress and
createmultisig RPC calls would let you violate that limit unknowingly.
Also made the wallet code itself check the redeemScript prior to adding
it to the wallet, which in the (rare) instance that a user has added an
invalid oversized redeemScript to their wallet causes an error on
startup. The affected key isn't added to the wallet; other keys are
unaffected.
Removes the limits on number of pubkeys for P2SH CHECKMULTISIG outputs.
Previously with the 500 byte scriptSig limit there were odd restrictions
where even a 1-of-12 P2SH could be spent in a standard transaction(1),
yet multisig scriptPubKey's requiring more signatures quickly ran out of
scriptSig space.
From a "stuff-data-in-the-blockchain" point of view not much has changed
as with the prior commit now only allowing the dummy value to be null
the newly allowed scriptSig space can only be used for signatures. In
any case, just using more outputs is trivial and doesn't cost much.

This is a source of transaction mutability as the dummy value was
previously not checked and could be modified to something other than the
usual OP_0 value.
- replaces checks in SendCoinsDialog::handlePaymentRequest() that belong
to PaymentServer (normal URIs are special cased, as only an isValid
check is done on BTC addresses)
- prevents the client to handle payment requests that do not match the
clients network and shows an error instead (mainly a problem with
drag&drop payment requests onto the client window)
- includes some small comment changes also
Size specifiers are no longer needed now that we use typesafe tinyformat

Generally useless information. Only updates on connect time, not after
that. Peers can easily lie and the median filter is not effective in
preventing that.
In the past it was used for progress display in the GUI but
`CheckPoints::guessVerificationProgress` provides a better way that is now used.
It was too easy to mislead it. Peers do lie about it in practice, see issue #4065.
From the RPC, `getpeerinfo` gives the peer raw values, which are more
useful.
Adds two new info query commands that take over information from
hodge-podge `getinfo`.
Also some new information is added:
- `getblockchaininfo`
- `chain`: (string) current chain (main, testnet3, regtest)
- `verificationprogress: (numeric) estimated verification progress
- `chainwork`
- `getnetworkinfo`
- `localaddresses`: (array) local addresses, from mapLocalHost (fixes#1734)

The year is 2014. All supported operating systems have IPv6 support,

of course).
If noone is exercising the functionality to disable it, that means it

Because this class replaces some usages of CBigNum, tests have been added to
verify that they function the same way. The only difference in their usage is
the handling of out-of-range numbers.
While operands are constrained to [-0x7FFFFFFF,0x7FFFFFFF], the results may
overflow. The overflowing result is technically unbounded, but in practice
it can be no bigger than the result of an operation on two operands. This
implementation limits them to the size of an int64.
CBigNum was unaware of this constraint, so it allowed for unbounded results,
which were then checked before use. CScriptNum asserts if an arithmetic
operation will overflow an int64_t, since scripts are not able to reach those
numbers anyway. Additionally, CScriptNum will throw an exception when
constructed from a vector containing more than 4 bytes This mimics the previous
CastToBigNum behavior.
- In wallet and GUI code LOCK cs_main as well as cs_wallet when
necessary
- In main.cpp SendMessages move the TRY_LOCK(cs_main) up, to encompass the call
to IsInitialBlockDownload.
- Make ActivateBestChain, AddToBlockIndex, IsInitialBlockDownload,
InitBlockIndex acquire the cs_main lock
Fixes#3997
All functions that use ChainActive but do not aquire the cs_main
lock themselves, need to be called with the cs_main lock held.
This commit adds assertions to all externally callable functions
that use chainActive or chainMostWork.
This will flag usages when built with -DDEBUG_LOCKORDER.
Drawback: The version string is no longer a valid git identifier.
For this reason the 'g' short hash prefix has been removed.
Exception: When building directly from a tag this behaves exactly like the previous behavior.
This allows formatting release versions with precision i.e. v0.9.2
This also allows arbitrary topicbranch names i.e. v0.9.1-glibc-compat
- prevents unsafe shutdowns on Windows, which is known to be
able to cause problems with wallet.dat
- if a users ends a Windows session, this will initiate a client shutdown
and show a Windows dialog, that tells the user what is going on (for
Windows Vista and higher it will even show a reason for blocking the
Windows session end)
glibc/libstdc++ have added new symbols in later releases. When running a new
binary against an older glibc, the run-time linker is unable to resolve the
new symbols and the binary refuses to run.
This can be fixed by adding our own versions of those functions, so that the
build-time linker does not emit undefined symbols for them.
This enables our binary releases to work on older Linux distros, while not
incurring the downsides of a fully static binary.
When we are over our outbound limit ThreadSocketHandler would try to
keep the connection if the peer was addnoded.
This didn't actually work for two reasons: It didn't actually run
the accept code due to mistaken code flow, and because we have a
limited number of outbound semaphores it couldn't actually use the
connection.
Instead it leaked the socket, which might have caused issue #4034.
This patch just takes out the non-functioning white-listing for now.
