"Fatal LevelDB error" when specifying -blockfilterindex=basic twice #17679
Description
My bitcoin.conf:
$ cat ~/.bitcoin/bitcoin.conf
[regtest]
blockfilterindex=basic
And if I launch bitcoind specifying ..=basic again, like this:
$ ./bitcoind -chain=regtest -blockfilterindex=basic
I get this error (full log below):
EXCEPTION: 15dbwrapper_error
Fatal LevelDB error: IO error: lock /home/vincas/.bitcoin/regtest/indexes/blockfilter/basic/db/LOCK: already held by process
bitcoin in AppInit()
Does not reproduce if I use -blockfilterindex=1 twice.
Expected behavior
Should not fatal-away due to redundant command line arguments.
Actual behavior
bitcoind exits with Fatal LevelDB error.
To reproduce
- Debian Sid
../configure --with-incompatible-bdb --with-gui=no(incompatileto use Debian's bdb)- Have
bitcoin.confas noted before. - Run
./bitcoind -chain=regtest -blockfilterindex=basic
System information
Bitcoin Core v0.19.0.1 and from current master
Debian Sid amd64.
Same with bitcoind and bitcoin-qt
