2018-09-27Merge #14244: amount: Move CAmount CENT to unit test headerMarcoFalke
fa84723e73 amount: Move CAmount CENT to unit test header (MarcoFalke) Pull request description: `CAmount` is currently not type-safe. Exporting a constant (`CENT`) that is commonly not referred to by that name might be confusing. `CENT` is only used in two places prior to this commit (`ParseMoney` and `MIN_CHANGE`). So replace these with constants relative to `COIN` and move `CENT` to the unit test header.

(Jim Posen) Pull request description: This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block. ### Filter Sizes [Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain. As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks: ![filter_sizes](https://user-images.githubusercontent.com/881253/42900589-299772d4-8a7e-11e8-886d-0d4f3f4fbe44.png) The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements. The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*: | Stat | Filter Type | |-------|--------------| | Weighted Size Ratio Mean | 0.0198 | | Size Ratio Mean | 0.0224 | | Size Ratio Std Deviation | 0.0202 | | Mean Element Size (bits) | 21.145 | | Approx Theoretical Min Element Size (bits) | 21.025 | Tree-SHA512: 2d045fbfc3fc45490ecb9b08d2f7e4dbbe7cd8c1c939f06bbdb8e8aacfe4c495cdb67c820e52520baebbf8a8305a0efd8e59d3fa8e367574a4b830509a39223f

e306be742932d4ea5aca0ea4768e54b2fc3dc6a0 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow) 48b1473c898129a99212e2db36c61cf93625ea17 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow) 18dfea0dd082af18dfb02981b7ee1cd44d514388 Always create 70 byte signatures with low R values (Andrew Chow) Pull request description: When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes. Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R. Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average. DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

2018-08-09Always create 70 byte signatures with low R valuesAndrew Chow
When extra entropy is not specified by the caller, CKey::Sign will now always create a signature that has a low R value and is at most 70 bytes. The resulting signature on the stack will be 71 bytes when the sighash byte is included. Using low R signatures means that the resulting DER encoded signature will never need to have additional padding to account for high R values.

However ProduceSignature is capable of doing this itself. Using both CombineSignatures and ProduceSignature results in code duplication which is unnecessary. To move the scriptSig construction to ProduceSignatures, the SignatureData class contains two maps to hold pubkeys mapped to signatures, and script ids mapped to scripts. DataFromTransaction is extended to be able to extract signatures, their public keys, and scripts from existing ScriptSigs. The SignaureData are then passed down to SignStep which can use the aforementioned maps to get the signatures, pubkeys, and scripts that it needs, falling back to the actual SigningProvider and SignatureCreator if the data are not available in the SignatureData. Additionally, Sign1 and SignN have been removed and their functionality inlined into SignStep since Sign1 is really just a wrapper around CreateSig. Since ProduceSignature can produce the final scriptSig or scriptWitness by using SignatureData which has extracted data from the transaction, CombineSignatures is unnecessary as ProduceSignature is able to replicate all of CombineSignatures' functionality. This also furthers BIP 174 support and begins moving towards a BIP 174 style backend. The tests have also been updated to use the new combining methodology.

2018-07-03Make SignatureData able to store signatures and scriptsAndrew Chow
In addition to having the scriptSig and scriptWitness, have SignatureData also be able to store just the signatures (pubkeys mapped to sigs) and scripts (script ids mapped to scripts). Also have DataFromTransaction be able to extract signatures and scripts from the scriptSig and scriptWitness of an input to put them in SignatureData. Adds a new SignatureChecker which takes a SignatureData and puts pubkeys and signatures into it when it successfully verifies a signature. Adds a new field in SignatureData which stores whether the SignatureData was complete. This allows us to also update the scriptSig and scriptWitness to the final one when updating a SignatureData with another one.

2018-05-30Stop translating command line optionsWladimir J. van der Laan
Many options are extremely technical, and refer internals, making it difficult to translate usefully. This came up in discussion of e.g. #10949. If a message is not understood by translators (which are typically end-users, not developers) they'll either translate it literally, making it harder to understand instead of easier, with the added drawback of the user no longer being able to google it. Also the translation was only working for bitcoin-qt as with the console programs, there is no translation backend. So it was injecting never-used translation messages for bitcoin-cli, -tx. For these reasons, stop translating options help completely. This should not affect the output **in any way** except for bitcoin-qt when a non-English language is configured in the locale. This implements #10962.
