gettxoutproof

Returns a hex-encoded proof that "txid" was included in a block.

NOTE: By default this function only works sometimes. This is when there is an unspent output in the utxo for this transaction. To make it always work, you need to maintain a transaction index, using the -txindex command line option or specify the block in which the transaction is included manually (by blockhash).

Arguments:

1. "txids" (string,required) A json array of txids to filter
  [
    "txid" (string) A transaction hash

Test example:

./qtum-cli gettxoutproof [\"5caa24c8c78f441a5c37dff602cdacc27b4530b03c09569f62dc3cd20e674918\"]

waitforlogs

waitforlogs (fromBlock) (toBlock) (filter) (minconf) requires -logevents to be enabled

Waits for a new logs and return matching log entries. When the call returns, it also specifies the next block number to start waiting for new logs. By calling waitforlogs repeatedly using the returned nextBlock number, a client can receive a stream of up-to-date log entires.

This call is different from the similarly named waitforlogs. This call returns individual matching log entries, searchlogs returns a transaction receipt if one of the log entries of that transaction matches the filter conditions.

Arguments:

1. fromBlock (int | "latest", optional, default=null) The block number to start looking for logs. ()
2. toBlock   (int | "latest", optional, default=null) The block number to stop looking for logs. If null, will wait indefinitely into the future.
3. filter    ({ addresses?: Hex160String[], topics?: Hex256String[] }, optional default={}) Filter conditions for logs. Addresses and topics are specified as array of hexadecimal strings
4. minconf   (uint, optional, default=6) Minimal number of confirmations before a log is returned

Result:

An object with the following properties:
1. logs (LogEntry[]) Array of matchiing log entries. This may be empty if `filter` removed all entries.2. count (int) How many log entries are returned.3. nextBlock (int) To wait for new log entries haven't seen before, use this number as `fromBlock`
Usage:
`waitforlogs` waits for new logs, starting from the tip of the chain.
`waitforlogs 600` waits for new logs, but starting from block 600. If there are logs available, this call will return immediately.
`waitforlogs 600 700` waits for new logs, but only up to 700th block
`waitforlogs null null` this is equivalent to `waitforlogs`, using default parameter values
`waitforlogs null null` { "addresses": [ "ff0011..." ], "topics": [ "c0fefe"] }` waits for logs in the future matching the specified conditions

echo|echojson "message" ...

Simply echo back the input arguments. This command is for testing.

The difference between echo and echojson is that echojson has argument conversion enabled in the client-side table inqtum-cli and the GUI. There is no server-side difference.

getmemoryinfo

Returns an object containing information about memory usage.

Arguments:

1. "mode" determines what kind of information is returned. This argument is optional, the default mode is "stats".
  - "stats" returns general statistics about memory usage in the daemon.
  - "mallocinfo" returns an XML string describing low-level heap state (only available if compiled with glibc 2.10+).

Result (mode "stats"):

{
  "locked": {               (json object) Information about locked memory manager
    "used": xxxxx,          (numeric) Number of bytes used
    "free": xxxxx,          (numeric) Number of bytes available in current arenas
    "total": xxxxxxx,       (numeric) Total number of bytes managed
    "locked": xxxxxx,       (numeric) Amount of bytes that succeeded locking. If this number is smaller than total, locking pages failed at some point and key data could be swapped to disk.
    "chunks_used": xxxxx,   (numeric) Number allocated chunks
    "chunks_free": xxxxx,   (numeric) Number unused chunks
  }
}

Result (mode "mallocinfo"):

"<malloc version="1">..."

Examples:

> qtum-cli getmemoryinfo 

> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getmemoryinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:3889/

help

List all commands, or get help for a specified command.

Arguments:

1. "command"     (string, optional) The command to get help on

Result:

"text"     (string) The help text

logging

Gets and sets the logging configuration.

When called without an argument, returns the list of categories with status that are currently being debug logged or not.

When called with arguments, adds or removes categories from debug logging and return the lists above. The arguments are evaluated in order "include", "exclude".

If an item is both included and excluded, it will thus end up being excluded.

The valid logging categories are: net, tor, mempool, http, bench, zmq, db, rpc, estimatefee, addrman, selectcoins, reindex, cmpctblock, rand, prune, proxy, mempoolrej, libevent, coindb, qt, leveldb, coinstake, http-poll.

In addition, the following are available as category names with special meanings:

  • "all", "1" : represent all logging categories.

  • "none", "0" : even if other logging categories are specified, ignore all of them.

Arguments:

1. "include"        (array of strings, optional) A json array of categories to add debug logging
     [
       "category"   (string) the valid logging category
       ,...
     ]
2. "exclude"        (array of strings, optional) A json array of categories to remove debug logging
     [
       "category"   (string) the valid logging category
       ,...
     ]

Result:

{                  
  "category": 0|1,  (numeric) if being debug logged or not. 0:inactive, 1:active
  ...
}

Examples:

> qtum-cli logging "[\"all\"]" "[\"http\"]"

> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "logging", "params": [["all"], "[libevent]"] }' -H 'content-type: text/plain;' http://127.0.0.1:3889/

stop
