    Overview

    Description This PR changes the return format of -getinfo

    Rationale

    • make -getinfo more user-friendly
    • uses less vertical screen space.

    Fixes: Issue 17314(Not linking issue to prevent it from closing)

    Alternative, more human-friendly, format besides JSON? Colors, progress bars

    Return Format

     0// Data from getblockchaininfo
 1Chain: [getblockchaininfo.chain] 
 2Blocks: [getblockchaininfo.blocks]
 3Headers: [getblockchaininfo.headers]
 4Verification progress: [getblockchaininfo.verificationprogress]
 5Difficulty: [getblockchaininfo.difficulty]
 6
 7# Data from getnetworkinfo
 8Network: in [getnetworkinfo.connections_in], out [getnetworkinfo.connections_out], total [getnetworkinfo.connections]
 9Version: [getnetworkinfo.version]
10Time offset (s): [getnetworkinfo.timeoffset]
11Proxy: [getnetworkinfo.proxy] // "N/A" if no proxy
12Min tx relay fee rate (BTC/kvB): [getnetworkinfo.relayfee]
13
14# Data from getwalletinfo. Will only be present when a single wallet is loaded
15Wallet: [getnetworkinfo.walletname] // "" if walletname is empty(default wallet)
16Keypool size: [getnetworkinfo.keypoolsize]
17Unlocked until: [getnetworkinfo.unlocked_until]
18Transaction fee rate (-paytxfee) (BTC/kvB): [getnetworkinfo.paytxfee]
19
20# Data from getbalances. Will only be present when a single wallet is loaded
21Balance: [getbalances.mine.trusted]
22
23# Data from listwallets then getbalances for each wallet. Will only be present for multiple wallets loaded
24Balances
25[getbalances.mine.trusted] [listwallets[i]] // Right justify on balance
26
27Warnings: [getnetworkinfo.warnings]

    Coloring

    The following lines would be colored to better show the differences between the various -getinfo components. However, this will not apply for WIN32(ANSI code not supported) and users that connect the stdout to a non-terminal process.

    • Chain: ...: BLUE(\x1B[34m)
    • Network: ...: GREEN(\x1B[32m)
    • Wallet: ...: MAGENTA(\x1B[35m)
    • Balance: ... CYAN(\x1B[36m)
    • Balances: ... CYAN(\x1B[36m)
    • Warnings: ... Yellow(\x1B[33m)

    Reviewing Notes

    Testing Scenarios

    1. No wallet loaded

    • When there no wallets are loaded(Unload wallet with ./src/bitcoin-cli unloadwallet "YOUR_WALLETNAME"
    • Test with ./src/bitcoin-cli -getinfo.
    • Should only display chain and network segment

    2. Single wallet loaded

    • When only a single wallet loaded or -rpcwallet is set(Load wallet with ./src/bitcoin-cli loadwallet "YOUR_WALLETNAME")
    • Test with ./src/bitcoin-cli -rpcwallet="YOUR_WALLETNAME" -getinfo(Load wallet with ./src/bitcoin-cli loadwallet "YOUR_WALLETNAME")
    • Should only display chain, network, wallet and balance segment

    3. Multiple wallet loaded

    • When there are multiple wallets loaded(Load wallet with ./src/bitcoin-cli loadwallet "YOUR_WALLETNAME")
    • Test with ./src/bitcoin-cli -getinfo
    • Should only display chain, network and balances segment

    Implementation

    Current Flow

    1. GetinfoRequestHandler is instantiated
    2. ConnectAndCallRPC is called with GetinfoRequestHandler. It returns UniValue::VOBJ result
    3. If -rpcwallet wallet is not set, GetWalletBalances is called with a pointer to result as a parameter. It adds the balances for all the wallets to result

    New Flow

    1. GetinfoRequestHandler is instantiated
    2. ConnectAndCallRPC is called with GetinfoRequestHandler. It returns UniValue::VOBJ result
    3. If -rpcwallet wallet is not set, GetWalletBalances is called with a pointer to result as a parameter. It adds the balances for all the wallets to result
    4. New ParseGetInfoResult is called with result as parameter. It converts results type from UniValue::VOBJ to UniValue::VSTR according to the format stated above.

    Concept ACK. Quick test below on signet. Build is clean, only skimmed the code for now.

    Ideas:

    • perhaps try displaying the balances before the wallet names, as the balances have a fixed length
    • maybe display the connections on one line connections: in 10, out 10, total 20…a good opportunity to save on vertical space, as getinfo was previously pruned down due to its output being considered too long
    • maybe s/Blockchain/Block chain/ (see https://github.com/bitcoinops/bitcoinops.github.io/blob/master/STYLE.md for a bitcoin writing guide)
    • add spaces between words like verificationprogress, relayfee, and timeoffset
    • maybe display "" for the default wallet

    @jonatack Updated the PR according to your comments:

    1. Swap position of wallet and balance and
    2. Prefix balance value with ₿ emoji to remove any ambiguity of what it represents
    3. display the connections on one line
    4. changed Blockchain to Block chain
    5. added space to verification progress, realy fee, time offset and keypool size(Should I also change paytxfee to pay tx fee?)
    6. display "" for default wallet

    I think this is nice. It looks better, is more user friendly, and at the same time discourages parsing the output in scripts and such (which is good because it is not intended as a stable interface).

    Are there still issues on windows with colorized text, or can basic ANSI color support be assumed all over the board now? (if not, you might want to put this in #ifndef WIN32, leave the strings empty if not—we do this for some python scripts)
    klementtan commented at 3:27 pm on May 4, 2021:

    hmmm I do not own a Windows computer and cannot test if ANSI color support works.

    Some questions (not sure they are good ideas!)

    The Bitcoin symbols are neat but I’m not sure they are needed…or maybe instead add just one symbol in parentheses after “Balances” in the header, e.g. Balances (B)…or insert a space between them and the balance?

    Should the field names be capitalized? e.g. s/verification progress/Verification progress/?

    Maybe hoist “chain: signet” to the header and shorten it to chain? e.g. “Chain: signet”, thereby removing a line…and if so, should that section be at the top, before the Network section?

    1. Capitalized all field names. s/verification progress/Verification progress/
    2. Changed unlocked_until to Unlocked until and paytxfee to Pay transaction fee
    3. Changed ₿0.000: wallet to Balances(₿) ... 0.000: wallet
    4. Combined chain: signet to Chain(signet)
    5. Moved Chain to be the top of the response.
    6. Updated cli_get_info_string_to_dict in test to a static method and changed string parsing method.

    What do you think about

    • s/Balance(₿):/Balance (₿):/ (insert a space)
    • extend the colors to the full line of Chain: <chain> and Balances (₿)
    • right-justify the balances to the largest balance, prefixing spaces to the smaller balances (-netinfo in this same file does it for some of the fields using strprintf)
    • maybe (not sure, might be too cluttered) hoisting the connections to the header: Network: in 17, out 22, total 49
    • in single-wallet mode, add the name: Wallet: <name>

    2. Combined Connections into Network header: Network: in <in>, out <out>, total <total>

    Oh, and if you need some sBTC (signet coins) for testing, here’s a faucet: https://signetfaucet.com (I can send you some too, if you need). @jonatack I hard-coded a fake wallet to simulate and test a large balance wallet but if you don’t mind sending me some sBTC to test it without hard-coding a wallet that would be great(address tb1q8rcmyqlphnpsemf8rgxpcwnlf0rvqnuqwhlzwf). Thanks!

  32. jonatack commented at 2:27 pm on May 13, 2021: member
    Sent you some signet coins (wow, the faucet used to be 10 sBTC and now it’s max .01). Thanks for updating! Looking pretty good. I think the balances alignment should based on the decimal point (apologies, I was unclear) which might require padding spaces after the balance as well if there are fewer than 8 digits after the decimal point (I thought there were always 8). And maybe we can omit the : after the balances. WDYT? I’ll re-test soon.
  33. klementtan commented at 3:45 pm on May 13, 2021: contributor

    Got it! Thanks for sending it to me and replying to me so quickly. My apologies the amount was hardcoded by me and I added fewer decimal places than what it would actually have. Here is the updated screenshot of what it would look like when one wallet contains “longer” balance than others

    And maybe we can omit the : after the balances

    Yup I agree <balance> <wallet> makes more sense as <balance> does not act as a key/field name.

    Edit:

    Updated PR to omit : image

    The diff in the above 15 lines in the “Test -stdinrpcpass option” section is unrelated formatting changes. I checked that it doesn’t change the code, but it’s easier and safer to review without them and normally they shouldn’t be added in this commit. I think they can probably be omitted.

    This cli_get_info_string_to_dict() function seems like a lot of workaround, would it be easier to drop this and test the stdout instead? I think we do that in other tests (feature_help.py, tool_wallet.py, etc). I guess it could be done later.

    Concept ACK

    Adding screenshots to your original post would be great.

    Some thinking out loud: For me it’s rather hard to say what keys are in result variable in ParseGetInfoResult. One way to solve that would be to introduce constants for strings like version, blocks, headers, verificationprogress, etc. so that an IDE can tell you where these JSON properties are used. This would help with refactorings too, I guess. The downside is that we would have more code. Feel free to ignore this note. If it resonates with you, it may be done in a follow-up PR. :)

    Some thinking out loud: For me it’s rather hard to say what keys are in result variable in ParseGetInfoResult.

    See the GetinfoRequestHandler class. I’m not sure the keys need to be hoisted out to a bunch of file-level static constants.

    Maybe ParseGetInfoResult() could be a method in the GetinfoRequestHandler class for better encapsulation.

  49. klementtan commented at 1:48 am on May 20, 2021: contributor

    Made the following changes:

    • Updated s/Time offset/Time offset (s) and s/Relay fee/ Relay fee (BTC/kB) image
    • Update release notes.

    Maybe ParseGetInfoResult() could be a method in the GetinfoRequestHandler class for better encapsulation. @jonatack I am not sure how to do that because GetWalletBalances takes in the return result of GetinfoRequestHandler and ParseGetInfoResult can only be called after GetWalletBalances is executed. Might need to refactor GetWalletBalances as well if we would like to encapsulate ParseGetInfoResult.

    Will work on refactoring the test to simplify it.

    I branch off from this branch in my own repo to implement testing against stdout(PR here) but I am not too sure if it actually simplifies the test because creating the expected stdout is quite complicated. @jonatack can I trouble you to take a look at it when you are free? If you agree with that rough approach I will merge it and you could review it here.

    Adding screenshots to your original post would be great. @kiminuo My bad. I misunderstood previous comments and was under the impression that screenshots are not allowed in PR description. Updated OP to include PR description. @kiminuo thanks for reviewing the PR 🙇‍♂️

    kiminuo commented at 6:26 am on May 20, 2021:

    I think that instead of "", it is more common to use [default wallet].

    At least these make me think so:

    jonatack commented at 6:50 am on May 20, 2021:
    In the RPC/CLI the default wallet has been "".
    kiminuo commented at 7:04 am on May 20, 2021:

    Is that user-friendly? I mean "" looks like an output for programmers and not for users. However, if it is a convention in CLI, then it’s better to align with it.

    One can possibly write also default wallet ("")

    jonatack commented at 7:13 am on May 20, 2021:

    If you need to specify the default wallet in the CLI or RPC, you pass "" or just nothing, e.g.:

    0$ bitcoin-cli -signet -rpcwallet="" -getinfo
1$ bitcoin-cli -signet -rpcwallet=  -getinfo

    If you pass something else, it won’t be recognized as the default wallet (unless there is some way I’m not aware of).

    If you have a wallet named “default wallet” then it seems your suggestion would make things confusing.

    kiminuo commented at 8:28 am on May 20, 2021:

    I see, that makes sense. Even though I was not suggesting to pass “default wallet” to a CLI command, just to make it clear that "" means a default wallet in the text output.

    Anyway, all is good.

  53. jonatack commented at 6:51 am on May 20, 2021: member

    Can I also ask:

    • Is it harder to review if I constantly squash my changes compared to squashing it at the end when everything is finalized?

    Is it harder to review if I constantly squash my changes compared to squashing it at the end when everything is finalized?

    Once the pull is complete and ready for more-or-less final review, I think it’s preferable to squash immediately, as git diff (or git range-diff) allows easily diffing the changes, particularly when you are looking for final review ACKs which would be held up by waiting for you to squash (see https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md#squashing-commits for more).

    Should I remove screenshots and markdown toggles from the PR description because it would be added as the commit message after the PR has been merged?

    Not sure about images, but markdown toggles maybe yes to not rely on markdown for it to make sense. At least avoid @-names and strike-through formatting; see https://jonatack.github.io/articles/how-to-contribute-pull-requests-to-bitcoin-core#pr-descriptions.

    1. Compiled and tested on Ubuntu. Bitcoin symbol unicode character was missing. Maybe we can avoid using it. Either mention nothing as balance in Bitcoin Core wallet will only be for Bitcoin and nothing else or write BTC after amount.

    Yeah, that makes sense since the Bitcoin symbol isn’t supported by default for all systems and it is just for novelty purposes. Removed the Bitcoin symbol in ef535b4

    1. nit: Pink color for wallet looks weird. Will be better if we could use some other color similar or same as color used for ‘balance’.

    Hmmm I am not too sure about this as the only other color that is left in ANSI Colour Code is red and I am afraid that it would give a false sense of danger to the user.

    Another approach would be to use bright cyan(\x1B[96m) for wallet(refer to screenshot below). However in my opinion, the difference between bright and non-bright color is too subtle and having a distinct color difference(ie using magenta) would be better.

    klementtan commented at 12:30 pm on June 1, 2021:

    Yup, they are all using python Decimal for the file. Correct if I am wrong but I think what @kiminuo meant is that using assert_equal for floats(float/Decimal) might lead to comparison errors and maybe another type of assertion should be used to check if the floats are “close enough”.

    However, I am and very new here, and might not know the nuance behind it.

    reg add HKEY_CURRENT_USER\Console /v VirtualTerminalLevel /t REG_DWORD /d 0x00000001 /f

    If we go with that approach does it mean that bitcoin core will no longer work out of the box for Windows users? In my opinion not having colors for WIN32 would be better than having to run an additional step of entering the reg add ... command as an administrator. What do you think? :)

    @sipa: Maybe this should only be enabled when stdout is connected to a terminal (isatty(stdout))?

    Is the purpose of this to not return ANSI codes when -getinfo is executed outside of the terminal?

    Side note: If the current handling of colored text is unsatisfactory I would prefer to remove all colored text support in this PR and create a separate PR for that. It seems that supporting colored text for every OS is quite complicated.

    @klementtan Right, when you’re sending output to a text file or through grep or something like that, you generally don’t want colorization.

    Colors don’t work on Windows with ANSI escape sequence by default. So making the changes that I suggested in #21832 (review) will change nothing but simplify code as we will use same code for Linux and Windows.

    If any user is curious and wants to use colors we can always suggest making changes in registry key. Else we will have to use windows.h and different code for Windows. IMO there are very less users who use Bitcoin Core on Windows and want to see colors in command prompt. So asking few power users who are curious to make changes in registry, use same code with less lines for every OS will be a better approach.

    Just tried running the code with suggested changes and registry key deleted. It doesn’t work as expected. Not sure if supporting colors on Windows makes sense. You can ignore the suggested changes.

    Thanks a lot for reviewing!

    I actually considered changing it to 2 decimal places but was on the fence for it. My concern is that currently 0.01% of the current height(686181) is about 6 blocks and displaying only 2 decimal places could confuse the user into thinking that their node is stuck. Additionally, as time goes on and the best height increases, I feel that it would be better to have a more granular value for verification progress.

    What do you think? If the others also feel that having 2 decimal places is better I would change it! 😄

    theStack commented at 10:48 pm on June 12, 2021:
    I think Isilva01’s proposal was primarily to change to per-cent unit, and the number of decimal places is just an example. Personally I’d also prefer showing in %; how about with 4 decimal places? With that, even a total block height of 1000000 (still years away) each single block verified results in a change of the verification progress display.

    Ran all three scenarios (no wallet, single wallet, multi-wallet) in OpenBSD 6.9 on mainnet and signet, works well and looks neat.

    Now interactively watching the IBD progress via e.g.

    0watch -n 1 -d ./src/bitcoin-cli -getinfo

    is quite a nice alternative to tail -f ~/.bitcoin/debug.log with less noise.

    Some follow-up ideas I could imagine:

    • also display date/time of latest block verified (maybe even the delta to the current time, to immediately see how far one is behind during IBD, or how long ago the last block was received, respectively)
    • also show on-disk size of the block chain (getblockchaininfo returns a field "size_on_disk")
    • show whether pruning is enabled
    • verification progress bar?

    The idea is that when somebody passes -color=nonsense, then you consider the value to be auto (no warning or so), right?
    klementtan commented at 9:09 pm on June 14, 2021:
    Yup! If they don’t enter a valid “when” value, it would be treated as the default colouring.
