doc: clarify loadwallet path loading for wallets

am-sq commented at 5:30 pm on June 18, 2024: none

Why this change?

#30269 describes a need for documentation improvement with the loadwallet RPC. Namely, some users have found the usage description confusing when it comes to loading wallets that are not in the normal case of being in the default wallet directory.

The default wallet directory, depending on the machine OS, has the base directory defined here: https://github.com/bitcoin/bitcoin/blob/9c5cdf07f30f816cd134e2cd2dca9c27ef7067a5/src/common/args.cpp#L699 which is then appended with /wallets. So for example, for MacOS, it would be ~/Library/Application Support/Bitcoin/wallets.

The changes implemented

Change the help text to indicate that the filename (or directory) passed in to loadwallet is relative to the base wallet directory
Adds additional examples to the help page showing how to fetch a wallet within a subdirectory of the base data directory for wallets, or from an absolute path

Thanks for the review. Is this description better? 

0You may pass in the absolute path of your wallet directory or .dat file. Otherwise, the interpreted path will be relative to the default wallet directory.

maflcko commented at 6:11 pm on June 18, 2024:

Do sqlite wallets allow .dat files to be passed, or is this only for BDB legacy wallets?

am-sq commented at 6:11 pm on June 18, 2024:

I can also add examples that load wallet using an absolute path.

am-sq commented at 7:05 pm on June 19, 2024:

Based on https://github.com/bitcoin/bitcoin/blob/master/doc/files.md#sqlite-database-based-wallets, it appears .dat files can be passed to sqlite wallets as well.

Tried createwallet to observe that the current version creates a directory with the given name, containing wallet.dat (and wallet.dat-journal while loaded).

Suggestion: put the normal/current/simplest operation first, and also add some descriptions to command examples:

0                    "\nLoad regular wallet with files under wallets/foo/:\n"

/Users/joe/specialWallets should be changed to /Users/joe/specialWallet/ here and in the RPC example since we only load one wallet at a time and to make clear that it is a directory.

Compiled and ran bitcoin-cli --regtest loadwallet without parameters. I like how you ended up alternating CLI/RPC examples.

Tested loadwallet "foo" just to make sure nothing funny happens with extra quotes.

I made the change to reflect different path string depending on OS. Let me know if this is what you meant. I was also debating doing an alternative way where 2 example types are displayed, one MacOS and other Unix, so that web docs like https://developer.bitcoin.org/reference/rpc/loadwallet.html show both examples.

Would have written it closer to something like:

 0    fs::path absolutePath;
 1#ifdef WIN32
 2    if (const char* homedrive = std::getenv("HOMEDRIVE"), * homepath = std::getenv("HOMEPATH");
 3        homedrive != nullptr && homedrive[0] != 0 && homepath != nullptr && homepath[0] != 0)
 4        absolutePath = fs::path(homedrive) / fs::path(homepath);
 5    else
 6        absolutePath = fs::path("C:\\Users\\Satoshi");
 7#else
 8    if (const char* home = std::getenv("HOME"); home != nullptr && home[0] != 0)
 9        absolutePath = fs::path(home);
10    else
11        absolutePath = fs::path("/home/satoshi");
12#endif
13    absolutePath /= fs::path("specialWallet") + fs::path::preferred_separator;

No old school Hungarian notation (pszHome -> home). (Also +const where possible).
See if char* is empty through checking first character instead of counting length of string (strlen()). Wish std::empty()had an overload for this but couldn’t find one.
Hopefully proper Windows path calculation (see Stackoverflow post).
Joe -> Satoshi. :)
absoluteSpecialWalletPath -> absolutePath (maybe absolutePathExample would be a good middle ground?), and type is fs::path all the way.
More common #preprocessor indentation.
/<name>/specialWallet/ -> /home/<name>/specialWallet/ when environment variable is nullptr.

Take from it what you want. Warning: other reviewers might disagree with me on something. If you prefer to keep your current version and others are fine with that, I will ACK too.

I don’t think the RPC documentation in the right place to inject and leak the name of the user that generated the docs. Among the obvious issues, this also makes them less deterministic.

I am sure a user can figure out what an absolute path means without having to see it in the docs.

If it was important to show this location, it can be returned by a dedicated RPC field?

hodlinator commented at 5:55 pm on June 26, 2024:

Hadn’t thought of the doc-generation aspect and leaks, good point.

hodlinator commented at 6:06 pm on June 26, 2024:

Just realized that in the console output in my latest test #30302#pullrequestreview-2142445372, the RPC --user is hardcoded to myusername:

0> curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "loadwallet", "params": [/home/hodlinator/.bitcoin/specialWallet/]}' -H 'content-type: application/json' http://127.0.0.1:8332/

So might as well use the same name if we want to go back to hardcoded platform-specific paths.

How about just hard-coding two examples- one for Unix and other for Windows? since I generally agree with

This seems to discuss passing in the absolute path of the .dat file. Saw the following behavior:

hodlinator commented at 9:54 pm on September 11, 2024:

Might be clearer like this:

0                    {"filename", RPCArg::Type::STR, RPCArg::Optional::NO, "You may pass in the absolute path of your wallet directory (or .dat file for legacy wallets). Otherwise, the interpreted path will be relative to the default wallet directory."},

murchandamus commented at 7:13 pm on September 12, 2024:

I agree with @hodlinator, and this may be a bit verbose for something that is output to the console. How about:

0                    {"filename", RPCArg::Type::STR, RPCArg::Optional::NO, "The path of the wallet directory (or a legacy wallet’s .dat file). Takes an absolute path or a path relative to the default wallet directory."},

This is definitely an improvement on the existing loadwallet help.

nit: I believe the RPC page listed in the commit message is actually derived from the help output of loadwallet. Technically this PR addresses the help output, and downstream things that use it would also benefit. I don’t really see a crucial need to change the commit message though, so feel free to ignore. If you happen to change something else, it might be good to also update the commit message.

Thanks for the additional examples and improving the documentation

doc: loadwallet loads from relative walletdir

Improves the documentation of help output for loadwallet
to clarify that filename is relative to the default
wallet directory. Adds examples that get a wallet from
sub-directories.

Checked changes since last ACK with git range-diff master 69bf58d b9aded4.

Adjusted commit message to not mention indirect documentation generation.
Incorporated feedback around .dat-file paths being for legacy wallets.

achow101 commented at 3:59 pm on September 20, 2024:

The relative path is relative to the wallet directory, not the default wallet directory. Starting with -walletdir=<dir> will change the wallet directory and specifying a wallet name in this argument will be interpreted to be relative to that walletdir.

pablomartin4btc commented at 11:18 pm on September 26, 2024:

We have already updated <filename> to <walletname> in a few places (bitcoin-cli.cpp and wallet/rpc/utils.cpp), shouldn’t be this the case as well? nit:

0                    {"walletname", RPCArg::Type::STR, RPCArg::Optional::NO, "The path to the wallet directory (absolute or relative to the wallets directory), or a legacy wallet's .dat file (within the wallets directory). The default wallets directory is the 'wallets' folder inside the data directory, unless the `-walletdir` option is specified."},
