This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.
|
|
Nothing is pruned, but this allows easier changes later.

The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.
Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.
|
|
for future expansion
|
|
This element is used in the generation of the MLSAG, but isn't
needed in verification.
Also misc changes in the cryptonote code to match, by mooo.
|
|
Saves some substantial space.
Also avoid calculating tx hashes we don't need.

They can be reconstructed from vout

Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.
This code relies on two things:
- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).
- the commitment must be directly after the rest of the data
in outkey and output_data_t.
|
|
to protect the non-signatures parts of the tx from tampering.
|
|
The mixRing (output keys and commitments) and II fields (key images)
can be reconstructed from vin data.
This saves some modest amount of space in the tx.
|
|
ie, more data or less data than expected in various fields
|
|
It may be suboptimal, but it's a pain to have to rebuild everything
when some of this changes.
Also, no clue why there seems to be two different code paths for
serializing a tx...

This plugs a privacy leak from the wallet to the daemon,
as the daemon could previously see what input is included
as a transaction input, which the daemon hadn't previously
supplied. Now, the wallet requests a particular set of
outputs, including the real one.
This can result in transactions that can't be accepted if
the wallet happens to select too many outputs with non standard
unlock times. The daemon could know this and select another
output, but the wallet is blind to it. It's currently very
unlikely since I don't think anything uses non default
unlock times. The wallet requests more outputs than necessary
so it can use spares if any of the returns outputs are still
locked. If there are not enough spares to reach the desired
mixin, the transaction will fail.

It's not really needed, it used to be an optimization for when
that code was not using the db and needed to recalculate things
fast on startup.

Compilation of bitmonero on Arch with gcc 6.1 results in the following
error:
/home/mwo/bitmonero/tests/unit_tests/hardfork.cpp: In member function ‘virtual void TestDB::set_hard_fork_version(uint64_t, uint8_t)’:
/home/mwo/bitmonero/tests/unit_tests/hardfork.cpp:132:5: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
if (versions.size() <= height) versions.resize(height+1); versions[height] = version;
This can be fixed by simply unfolding this line into three lines.

This is a list of existing output amounts along with the number
of outputs of that amount in the blockchain.
The daemon command takes:
- no parameters: all outputs with at least 3 instances
- one parameter: all outputs with at least that many instances
- two parameters: all outputs within that many instances
The default starts at 3 to avoid massive spamming of all dust
outputs in the blockchain, and is the current minimum mixin
requirement.
An optional vector of amounts may be passed, to request
histogram only for those outputs.

Some word triplets, such as "mugged names nail", are not valid
results from any 32 bit value. If used to decode a 32 bit value,
the result will therefore encode to a different word triplet.
Fix this by using random words converted from an actual random
bitstring, ensuring we always get valid triplets.

Needed to add the corresponding (dummy) method to unit test hardfork
|
|
open isn't actually called in those tests
|
|
|
|
|
|
The dummy blockchain class needed to have the newly added
is_read_only virtual function.
|
|
|
|
A couple stopped passing when the hard fork code was made
to reject incoming hard fork versions it did not know about.
|
|
|
|
This would fail, as the post hard fork settings would yield
different data, and the test expects pre hard fork data.
|
|
|
|
|
|
Also add some more tests, and rename some instances of
"version" and "add" for clarity.
NOTE: the starting height values are sometimes wrong.
I suspect this is due to the hard fork reorg code being
buggy, since they're good when syncing after the fact.
However, they're not actually used by the consensus code,
so I'm ignoring this for now, but this needs debugging.
|
|
version 2
|
|
It returns the ideal version for a given height, which is
based on the minimum height for a fork, disregarding votes
|
|
And setup the first fork to not vote
|
|
|
|
git history's here if needed to get any of this back
|
|
|
|
Using major version would cause older daemons to reject those
blocks as they fail to deserialize blocks with a major version
which is not 1. There is no such restriction on the minor
version, so switching allows older daemons to coexist with
newer ones till the actual fork date, when most will hopefully
have updated already.
Also, for the same reason, we consider a vote for 0 to be a
vote for 1, since older daemons set minor version to 0.
|
|
|
|
Add a block height before which version 1 is assumed
Use DB transactions
|
|
This allows knowing the hard fork a block must obey in order to be
added to the blockchain. The previous semantics would use that new
block's version vote to determine this hard fork, which made it
impossible to use the rules to validate transactions entering the
tx pool (and made it impossible to validate a block before adding
it to the blockchain).
|
|
There will be a delay on first load of an existing blockchain
as it gets reparsed for this state data.
|
|
This keeps track of voting via block version, in order to decide
when to enable a particular fork's code.
|
|
This ensures one can't instanciate a DNSResolver object by
mistake, but uses the singleton. A separate create static
function is added for cases where a new object is explicitely
needed.

Based on tewinget's update.
Make OpenAlias address format independent of existing DNS functions.
Add tests.
Test:
make debug-test
cd build/debug/tests/unit_tests
# test that regular DNS functions work, including IPv4 lookups.
# also test function that converts OpenAlias address format
make && ./unit_tests --gtest_filter=DNSResolver*
# test that OpenAlias addresses like donate@getmonero.org work from
# wallet tools
make && ./unit_tests --gtest_filter=AddressFromURL.Success

old unbound #warning does not block compilation
unit tests build fine. Even though the RPC/P2P network type is required again

DNSSEC is now implemented with the hardcoded key from unbound.
This will need to be not hardcoded in the future, but is okay for now.
Unit tests updated for DNSSEC (as well as for the fact that, contrary to
previous assumption, example.com does not have a static IP address).
|

Everything except actually *using* BlockchainBDB is wired up, but the db
itself is not yet working. Some error about user mem not large enough.
I think I know what this error means, but I can't determine the cause.
Notes: BerkeleyDB does not allow 0-indexing in its recno type databases,
so block numbers *in the database* will be 1-indexed. Modifications
to indexing have been made as needed.
|
|
Make Cmake things aware of BerkeleyDB and BlockchainBDB
Make the BlockchainDB unit tests aware of BlockchainBDB

Fixed the windows path, and improved logging and data
(for graph) logging, fixed some locks and added more checks.
Still there is a locking error,
not added by my patches, but present in master version
(locking of map/list of peers).
|
|
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)
|
|
|
|
Some BlockchainDB unit testing fleshed out (and working), rudimentary
linker flag for lmdb in CMakeLists, but should probably be done
"correctly" at some point (find it on whatever system you're building on
and all that jazz).
update for rebase (warptangent 2015-01-04)
fix conflicts with upstream CMakeLists.txt files
tests/CMakeLists.txt (remove edits from original commit)
|
|
miscellaneous changes to BlockchainDB/blockchain as well, namely
replacing instances of std::list with std::vector
|
|
|
|
Older versions of CMake support LINK_{PUBLIC,PRIVATE} while newer
versions prefer PUBLIC and PRIVATE instead, but still support the LINK_
prefix.

Note: DNSResolver does not yet *use* DNSSEC, but rather this commit is
preparation for including DNSSEC validation. The function in
src/wallet/wallet2.cpp that uses DNSResolver still needs its parameters
updated accordingly.
