a86e81b78f travis: move back to the minimal image
The most recent update replaced the minimal image with a large one for the
'generic' image. Switching back to 'minimal' should reduce dependencies and
maybe speed us up some.

It should also eliminiate the need for aa2e0f09e.

Pull request description:

  This should fix issues with the multiwallet test and its symlinks

  Rather than fixing os.symlink to work with paths relative to a
  directory descriptor, which does not work on Windows, normalize
  the path instead.

Merge #11062: [mempool] Mark mempool import fails that were found in mempool as 'already there'
258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm)

Pull request description:

  I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool.

  This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'.

  Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

  - while there, do some general tidying up of the module - fix flake8 warnings, make initialization code more compact
  - All classes in Python3 are new-style. No need to explicitly inherit from `object`.

cb06edf938 Fix wallet RPC race by waiting for callbacks in sendrawtransaction 2017-10-13 19:30:15 -04:00
Matt Corallo
e545dedf72 Also call other wallet notify callbacks in scheduler thread
This runs Block{Connected,Disconnected}, SetBestChain, Inventory,
and TransactionAddedToMempool on the background scheduler thread.

Of those, only BlockConnected is used outside of Wallet/ZMQ, and
is used only for orphan transaction removal in net_processing,
something which does not need to be synchronous with anything
else.

This partially reverts #9583, re-enabling some of the gains from
 #7946. This does not, however, re-enable the gains achieved by
repeatedly releasing cs_main between each transaction processed.

17220d6325 Use callbacks to cache whether wallet transactions are in mempool
This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.

Thanks to @morcos for the suggestion to do this.

Note that there are several race conditions introduced here:

 * If a user calls sendrawtransaction from RPC, adding a
   transaction which is "trusted" (ie from them) and pays them
   change, it may not be immediately used by coin selection until
   the notification callbacks finish running. No such race is
   introduced in normal transaction-sending RPCs as this case is
   explicitly handled.

 * Until Block{Connected,Disconnected} and
   TransactionAddedToMempool calls also run in the CSceduler
   background thread, there is a race where
   TransactionAddedToMempool might be called after a
   Block{Connected,Disconnected} call happens.

 * Wallet will write a new best chain from the SetBestChain
   callback prior to having processed the transaction from that
   block.

[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."

44407100f Replace relevant services logic with a function suite. (Matt Corallo)

Pull request description:

  This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.

  Adds HasAllRelevantServices and GetRelevantServices, which check
  for NETWORK|WITNESS.

  This changes the following:
   * Removes nRelevantServices from CConnman, disconnecting it a bit
     more from protocol-level logic.
   * Replaces our sometimes-connect-to-!WITNESS-nodes logic with
     simply always requiring WITNESS|NETWORK for outbound non-feeler
     connections (feelers still only require NETWORK).
   * This has the added benefit of removing nServicesExpected from
     CNode - instead letting net_processing's VERSION message
     handling simply check HasAllRelevantServices.
   * This implies we believe WITNESS nodes to continue to be a
     significant majority of nodes on the network, but also because
     we cannot sync properly from !WITNESS nodes, it is strange to
     continue using our valuable outbound slots on them.
   * In order to prevent this change from preventing connection to
     -connect= nodes which have !WITNESS, -connect nodes are now
     given the "addnode" flag. This also allows outbound connections
     to !NODE_NETWORK nodes for -connect nodes (which was already true
     of addnodes).
   * Has the (somewhat unintended) consequence of changing one of the
     eviction metrics from the same
     sometimes-connect-to-!WITNESS-nodes metric to requiring
     HasRelevantServices.

  This should make NODE_NETWORK_LIMITED much simpler to implement.

Merge #7061: [Wallet] Add RPC call "rescanblockchain <startheight> <stopheight>"
7a91ceb5e [QA] Add RPC based rescan test (Jonas Schnelli)
c77170fbd [Wallet] add rescanblockchain <start_height> <stop_height> RPC command (Jonas Schnelli)

Pull request description:

  A RPC rescan command is much more flexible for the following reasons:
  * You can define the start and end-height
  * It can be called during runtime
  * It can work in multiwallet environment

f4c4e38884 [trivial] Make namespace explicit for is_regular_file
is_regular_file resolves using argument dependent lookup. Make the
namespace explicit so it's obvious where the function is defined.
