The destructors get a noexcept(true) spec by default, but these
destructors in fact throw exceptions. An alternative fix might be to not
throw (most if not all of these throws are non-essential
error-reporting/logging).

GCC warned about this one.
|
|
This list is already defined within the function. The
removed definition was shadowed.
|
|
|
|
Btw, the warning 4200 remains disabled, but it did not get triggered
(GCC 6.1.1, ARM). But, perhaps a better way than disabling
the warning would be to do what is suggested here:
http://stackoverflow.com/questions/3350852/how-to-correctly-fix-zero-sized-array-in-struct-union-warning-c4200-without%3E

And add a thread safe version to encourage proper use

The tests for rejection of unmixable outputs in v2 are commented out,
as there are no unmixable outputs created anymore. This should be
restored at some point.

They're not fatal, though indicate something wrong

Do it before the generate() call so the value actually gets stored.
|

Don't prompt for restore-height on generate-new-wallet
|
|
|
|
It sets the max number of threads to use for a parallel job.
This is different that the number of total threads, since monero
binaries typically start a lot of them.
|
|
It allows a simple get_transfers (with default 0 min_height and
max_height) to return all transactions, instead of the unexpected
set of txes in block 0, which is probably none at all.
|
|
|
|
|
|
Allows getting in, out, pending, and failed transfers, similarly
to the show_transfers command.
|
|
|
|
|
|
Delete old indices and recreate them, rather than updating them
Maybe not quite as slow as before.
|
|
Avoids silent use of bad RNG in release builds, in case those
calls might actually fail.

We want to lock operations which access the blockchain in
wallet2. We also want the background refresh to happen again
when we cancel a foreground refresh. Wrap the locking setup
in a macro so it doesn't get copy/pasted/mangled, and use
a scope exit trick to ensure it's always properly restored.
|
|
This sends all outputs in a wallet to a given address, alleviating
the difficulty people have had trying to send all monero but
being left with some small amount left.

Update to fix unconfirmed balance and give a slightly more verbose and informative confirmation message for transfers
|
|
For specifying the block height from which to start a restore
|
|
Use the current blockchain height as the refresh_from_block_height.
|
|
When m_refresh_from_block_height has been set, only hashes will be
retrieved up to that height, instead of full blocks. The same will
be done for "refresh <height>" when the specified height is beyond
the current local blockchain.
|
|
When reaching the tail emission phase, the amount of coins will
eventually go over MONEY_SUPPLY, overflowing 64 bits. There was
a check added to blockchain_storage, but this was not ported to
the blockchain DB version.
Reported by smooth.
|

Avoids possible issues with accepting a tx too large to fit
in an actual block.
Reported by smooth.
|
|
If there is no comms error, but the response is not as expected,
close would not be called.
|
|
|
|
^C when in RPC mode would not save the wallet while it was still
refreshing after starting up.
Also, save the wallet out of the signal handler. We don't want
to call complex stuff in a signal handler.
|
|
|
|
Migrate from DB version 0 to version 1 on startup
|
|
|
|
Useful to ensure files are written without group/other read rights.
|
|
As pointed out by smooth, a transaction's validity may change
over time as the blockchain changes.
|
|
|
|
drop obsolete remove_output()
fix get_output_key(global), fix crash in blockchain_dump
|
|
Try to rationalize the variable names, document usage.
|
|
Helps when they're called repeatedly in one txn
|
|
Saves another ~150MB or so on the full blockchain
|
|
Also bumped DB VERSION to 1
Another significant speedup and space savings:
Get rid of global_output_indices, remove indirection from output to keys
This is the change warptangent described on irc but never got to finish.
|
|
Saves another 90MB on 200000 block import.
Had to bring back compare_uint64 for this, but it's safe since
this table is always 64-bit aligned.
|
|
Small space savings, no measurable speedup
|
|
Only a small savings...
|
|
|
|
m_tx_outputs doesn't need to be changed, as it's no longer dup list.
|
|
This is possible on those using a tx index as a key.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This speeds up wallet refresh by directly retrieving a tx's amount output indices.
It removes the indirection and walking the amount output duplicate list
for every amount in each requested tx.
"tx_outputs" is used by:
Amount output indices are needed for wallet refresh.
Global output indices are needed for removing a tx.
Both amount output indices and global output indices are now stored in
an array of 64-bit unsigned ints:
tx_outputs[<tx_hash>] -> [ <a1_oi, a1_gi, a2_oi, a2_gi, ...> ]
Previously it was:
tx_outputs[<tx_hash>] -> duplicate list of <a1_gi, a2_gi, a3_gi, ...>
The amount output list had to be walked for every amount in order to
find each amount's output index, by comparing the amount's global output
index with each one in the duplicate list until a match was found.

Add support for short/integrated/encrypted IDs to get_payments RPC
|
|
|
|
Just to make it easier
|
|
|
|
When present, it can be used to validate the keys, as well
as deduce the spend key, if it is absent (watch wallet).
|
|
|
|
This now requests the set of outputs that can be mixed first,
to avoid trying non dust but unmixable outputs, which we know
will fail.
|
|
For unknown reasons, it was generated with a block reward
consisting of a single large dusty output.
|
|
|
|
This can generate non decomposed outputs for very large block
rewards (or not so large ones if a miner decides to not quantize
the block rewards). Out of an abundance of caution, we refuse
to generate those. They are still accepted by the consensus code,
however.

With code to help factor out reading typed fields from JSON
|
|
This allows appropriate action to be taken, like displaying
the reason to the user.
Do just that in simplewallet, which should help a lot in
determining why users fail to send.
Also make it so a tx which is accepted but not relayed is
seen as a success rather than a failure.
|
|
|
|
Because we can.
|
|
This will be slower, though more private.
New trusted_daemon parameter to the matching RPC call, false by default.
|
|
With the change in mixin rules for v2, the "annoying" outputs are
slightly changed. There is high correlation between dust and
unmixable, but no equivalence.
|
|
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.
|
|
It resulted in a tx being sent with too low a fee, and thus rejected.
|
|
|
|
This was meant to go in v2, but the miner tx slipped through
the cracks as it doesn't go through the main tx verification
since it doesn't get added to the pool.

It takes a filename containing JSON data to generate a wallet.
The following fields are valid:
version: integer, should be 1
filename: string, path/filename for the newly created wallet
scan_from_height: 64 bit unsigned integer, optional
password: string, optional
viewkey: string, hex representation
spendkey: string, hex representation
seed: string, optional, list of words separated by spaces
Either seed or private keys should be given. If using private
keys, the spend key may be omitted (the wallet will not be
able to spend, but will see incoming transactions).
If scan_from_height is given, blocks below this height will not
be checked for transactions as an optimization.

tx_pool.h doxygen documentation completed.
Many notes made on areas for improvement, be that functionality or
code clarity.
Commented code and unused code removed.
|

BlockchainDB is now Doxygen-compliant and its documentation is
up-to-date with recent changes.

The functions in src/cryptonote_core/checkpoints_create.{h,cpp} should
be member functions of the checkpoints class, if nothing else for the
sake of keeping their documentation together.
This commit covers moving those functions to be member functions of the
checkpoints class as well as documenting those functions.
|
|
All functions in src/cryptonote_core/checkpoints.h are now documented in
doxygen style.
checkpoints.cpp has been reviewed, one function has been marked for
discussion on correctness.
|
|
|
|
All functions are now documented in doxygen format. Comments have been
updated to reflect the current state of the code. Many areas for
improvement in clarity and design have been noted, as well as cruft to
be removed. These changes are not reflected in this commit both to
allow time for comment and to keep commits organized by purpose.

It's logging the blockchain height, not the top block height
|
|
It was only filling the input in non rpc mode
|

Make sure we stop the right txn too

save the thread ID of the writer thread so we don't try to use
the writetxn from reader threads

|
It would try to join the auto refresh thread, which would
only happen after it was done, which would take a long time
when doing so on a newly created wallet.
|
|
Because obviously it doesn't work as other POSIX platforms.
Reported and tested by luigi1111.
|
|
The blocked ip list will still hold them till next time
a connection attempt is made with that IP, so the effective
length of the ban may be negative.
|
|
|
|
After the fork, normal transfer functions called via RPC
use the minimum mixin 2 if 0 or 1 is requested. While the
incoming transaction may be valid (eg, it has an unmixable
and at most a mixable input), it is a simple way to make
sure RPC users can't get a seemingly random accept/reject
behavior if they don't update their requested mixin.
|

We will need it in the wallet RPC server

TEST:
blockchain_export -h
This should show "berkeley" as an available option to --database.
With an existing BerkeleyDB database, run:
blockchain_export --database berkeley
|
|
|
|
|
|
|
|
This is already the default for the daemon, but by checking a command
line argument and calling a Blockchain member function setter.
Initialize the variable to false so it's not dependent on an external
command-line argument check. This allows utilities like
blockchain_import to have a reasonable default without code changes.
|
|
We don't need it now with per-txn cursors.

When keys are contiguous and monotonically increasing, this gets
denser page utilization (doesn't leave padding in page splits).
Can't be used for keys that are inserted in random order (e.g. hashes)
In total this only saves around 1.5% of space compared to original
DB code. The previous patch accounted for 0.8% savings on its own;
the blocks tables just aren't that big.
|
|
Saves a bit of seek overhead. LMDB frees them automatically
in txn_(commit|abort) so they need no cleanup.

These modes match those optionally provided as part of the daemon's
--db-type argument.
Argument after the # is interpreted as a composite mode if there's only
one (no comma separated arguments).
Sample usage:
blockchain_import --database lmdb#fastest
blockchain_import --database berkeley#fastest
Multiple specific DB flags are still supported, e.g.
blockchain_import --database lmdb#nosync,nordahead
blockchain_import --database berkeley#txn_nosync

|
|
Add another DB error exception type to distinguish failed txn setup from
general use of txn.
This keeps the error handling flow the same as before the block-level
txn setup changes that moved control up a layer to BlockchainDB.
|
|
This hasn't been known to occur in block-level txn abort, but throw
exception if it does.

Remove LINK_SEARCH_START_STATIC and LINK_SEARCH_END_STATIC. This is more
appropriate when the compiler flag -static is used.
This had been causing CMake to omit the linker flags necesssary to
distinguish static and dynamic library linking. CMake had assumed static
linking for the target, causing it to omit explicit static link flags.
That is problematic without the -static compile flag being set.
With a library located in system directories, like libboost_date_time,
the full static path (.a), though found correctly by CMake, was treated
by the linker as a dynamic library. This is because
target_link_libraries() transforms the full path to -l<libname> if it's
in a system directory. Without -static or explicit linker flags, the
dynamic library (.so) is linked.
Removing the above two properties removes the assumption of static. So
-Wl;-Bstatic is inserted where needed. This causes -l<libname> to
properly refer to the static library instead of dynamic.
