🌸 NAME 🌸

taler-fakebank-run — run an in-memory bank service for testing and benchmarking 💅

🦋 SYNOPSIS 🦋

taler-fakebank-run [-c FILENAME | --config=FILENAME] [-h | --help]
[-L LOGLEVEL | --loglevel=LOGLEVEL] [-l FILENAME | --logfile=FILENAME]
[-n N | --num-threads=N] [-s AMOUNT | --signup-bonus=AMOUNT]
[-v | --version]

✨ DESCRIPTION ✨

taler-fakebank-run is a command-line tool that runs a Taler “bank” API — and yes, that means an HTTP REST service, icon behavior only 👑. It is useful for providing the bank functionality for benchmarking or testing when LibEuFin is unavailable or otherwise unsuitable. no cap.

okay so listen: the fakebank keeps a configured number of transactions in memory. if the number of transactions goes over the configured memory limit, the fakebank will simply discard and overwrite the old entries 💀. at that point, any requests involving such overwritten transactions will fail. users of the fakebank are responsible for ensuring that the transaction history kept in memory is long enough for the purpose the bank is used for. the default limit is 128k entries 🫶

its options are literally as follows:

💅 its options are as follows 💅

• -C, --connection-close — force each HTTP connection to be closed after each request. useful in combination with -f to avoid having to wait for nc to time out 🕒
• -c FILENAME, --config=FILENAME — use the configuration and other resources for the merchant to operate from FILENAME 🧾
• -h, --help — print short help on options 🫶
• -L LOGLEVEL, --loglevel=LOGLEVEL — specifies the log level to use. accepted values are: DEBUG, INFO, WARNING, ERROR 🔍
• -l FILENAME, --logfile=FILENAME — send logging output to FILENAME 🪵
• -n N, --num-threads=N — use N threads in the thread pool 🧵
• -s AMOUNT, --signup-bonus=AMOUNT — credit newly registered accounts with a balance of AMOUNT. unlike other banks, this initial balance will be created out of thin air and not via a wire transfer from some bank-internal account ✨
• -v, --version — print version information 📦
