--write-config/--read-config is broken

$ ./miniZ --version
miniZ v2.2c @ Sep 19 2023 23:25:44

I have found in FAQ that config file could be created with --write-config. It doesn't work well...

I tried mine BTG at 2miners. miniZ in this case creates config file but it crashes when started with ./miniZ --read-config

$ cat btg-2m-test.sh

POOL="btg.2miners.com:4040"

./miniZ --url="$WALLET.$WORKER@$POOL" --log --extra "$@"

Write config file, it works:

$ sh btg-2m-test.sh --write-config

Try to run miniZ with config, it crashes:

When I run miniZ with parameters directly (or sh btg-2m-test.sh), it works:

When miniZ is started with combination of --ocX --write-config, config file is not created and miniZ starts to mine...

Demo for UNMINEABLE pool:

$ cat btg-um-test.sh
#!/bin/sh

WORKER="MINIZ"
WALLET="BTC:1CZwzXAuMTXb2MXDTEz4KgFcauo6oVqvuv"
REF="gudm-88g0"

POOL="zhash.unmineable.com:3333"
USER="$WALLET.$WORKER#$REF"
PASS="x"

./miniZ --par 144,5 --pers BgoldPoW --url="$WALLET.$WORKER#$REF@$POOL" --log --extra "$@"

No config is written, miniZ starts to mine:

$ sh btg-um-test.sh --ocX --write-config

Config is created in this case:

$ sh btg-um-test.sh --write-config

miniZ.conf is valid JSON file but miniZ cannot read config, it crashes:

$ ls -l miniZ.conf

BTW, username for mining at UNMINEABLE is more complex, it has format COIN:WALLET.WORKER#REFERENCE, for example BTC:1CZwzXAuMTXb2MXDTEz4KgFcauo6oVqvuv.miniz#gudm-88g0

miniZ-miner / miniZ

--write-config/--read-config is broken #30
