6aab7649d30b19d136a27f1287fd2c8b00fb460c doc: Fix whitespace errs in .md files, bitcoin.conf, Info.plist.in, and find_bdb48.m4 (Jon Layton)
Pull request description:
Although there is an existing `test/lint/lint-whitespace.sh` linter, it only prevents new errors from being introduced. This commit removes all existing whitespace errors from Core markdown files (skips `src/crypto/ctaes/`, `leveldb/`, and `doc/release-notes/`), `bitcoin.conf`, and `Info.plist.in`.
Further formatting could be done on the markdown documents, but seeing as there several coexisting styles that break a few `markdownlint` rules, a first step would be to define and add a linter to Travis. For now, the small fix is made.

ACK 6aab7649d30b19d136a27f1287fd2c8b00fb460c - Thanks for following up. Hopefully we now never have to deal with whitespace again.

Unauthenticated REST Interface
|
|
==============================
|
|
|
|
The REST API can be enabled with the `-rest` option.
|
|
|
|
The interface runs on the same port as the JSON-RPC interface, by default port 9998 for mainnet and port 19998 for testnet.
|
|
|
|
REST Interface consistency guarantees
|
|
-------------------------------------
|
|
|
|
The [same guarantees as for the RPC Interface](/doc/JSON-RPC-interface.md#rpc-consistency-guarantees)
|
|
apply.
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
There is a known issue in the REST interface that can cause a node to crash if
|
|
too many http connections are being opened at the same time because the system runs
|
|
out of available file descriptors. To prevent this from happening you might
|
|
want to increase the number of maximum allowed file descriptors in your system
|
|
and try to prevent opening too many connections to your rest interface at the
|
|
same time if this is under your control. It is hard to give general advice
|
|
since this depends on your system but if you make several hundred requests at
|
|
once you are definitely at risk of encountering this issue.
|
|
|
|
Supported API
|
|
-------------
|
|
|
|
#### Transactions
|
|
`GET /rest/tx/<TX-HASH>.<bin|hex|json>`
|
|
|
|
Given a transaction hash: returns a transaction in binary, hex-encoded binary, or JSON formats.
|
|
|
|
By default, this endpoint will only search the mempool.
|
|
To query for a confirmed transaction, enable the transaction index via "txindex=1" command line / configuration option.
|
|
|
|
#### Blocks
|
|
`GET /rest/block/<BLOCK-HASH>.<bin|hex|json>`
|
|
`GET /rest/block/notxdetails/<BLOCK-HASH>.<bin|hex|json>`
|
|
|
|
Given a block hash: returns a block, in binary, hex-encoded binary or JSON formats.
|
|
Responds with 404 if the block doesn't exist.
|
|
|
|
The HTTP request and response are both handled entirely in-memory.
|
|
|
|
With the /notxdetails/ option JSON response will only contain the transaction hash instead of the complete transaction details. The option only affects the JSON response.
|
|
|
|
#### Blockheaders
|
|
`GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json>`
|
|
|
|
Given a block hash: returns <COUNT> amount of blockheaders in upward direction.
|
|
Returns empty if the block doesn't exist or it isn't in the active chain.
|
|
|
|
#### Blockhash by height
|
|
`GET /rest/blockhashbyheight/<HEIGHT>.<bin|hex|json>`
|
|
|
|
Given a height: returns hash of block in best-block-chain at height provided.
|
|
|
|
#### Chaininfos
|
|
`GET /rest/chaininfo.json`
|
|
|
|
Returns various state info regarding block chain processing.
|
|
Only supports JSON as output format.
|
|
* chain : (string) current network name as defined in BIP70 (main, test, regtest)
|
|
* blocks : (numeric) the current number of blocks processed in the server
|
|
* headers : (numeric) the current number of headers we have validated
|
|
* bestblockhash : (string) the hash of the currently best block
|
|
* difficulty : (numeric) the current difficulty
|
|
* mediantime : (numeric) the median time of the 11 blocks before the most recent block on the blockchain
|
|
* verificationprogress : (numeric) estimate of verification progress [0..1]
|
|
* chainwork : (string) total amount of work in active chain, in hexadecimal
|
|
* pruned : (boolean) if the blocks are subject to pruning
|
|
* pruneheight : (numeric) highest block available
|
|
* softforks : (array) status of softforks in progress
|
|
* bip9_softforks : (object) status of BIP9 softforks in progress
|
|
|
|
#### Query UTXO set
|
|
`GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n>/.../<txid>-<n>.<bin|hex|json>`
|
|
|
|
The getutxo command allows querying of the UTXO set given a set of outpoints.
|
|
See BIP64 for input and output serialisation:

Example:
|
|
```
|

|
|
|

|
|

|
|
* loaded : (boolean) if the mempool is fully loaded
|

Risks
|
|
-------------
|
|
Running a web browser on the same node with a REST enabled dashd can be a risk. Accessing prepared XSS websites could read out tx/block data of your node by placing links like `<script src="http://127.0.0.1:19998/rest/tx/1234567890.json">` which might break the nodes privacy.
