[Bitcoin-development] [QT] how to disable block verification for faster UI testing?

the command line options mention a -checklevel  parameter.
I've been passing 0 assuming there'd be little to no verification, but it's
happened a few times that when I open the official binary (while not doing
development) there's some sort of database corruption and Bitcoin-Qt needs
to reindex blocks on disk, a process that can take probably a whole day.

how do you guys develop the UI and avoid these issues?

In general I do very little with the database while developing the UI. I
have various seperate bitcoin data directories (both testnet and mainnet)
to try things out. Before doing something risky I just make a copy.

These days I also do a lot of development with -regtest, as it allows
quickly setting up test scenarios.

What are you trying to test specifically? The progress bar while reindexing?

If you have database problems are you perhaps switching between 0.8.x and
0.9.x with the same directory? In that case see the downgrading warning
here: https://bitcoin.org/bin/0.9.0/README.txt .

"If you have database problems are you perhaps switching between 0.8.x and

I think that may have been the issue.

Maybe now that I have a 0.9.0 official binary, when I switch to the source
builds I won't have the issue.

However, I think I'll do what you do and have separate bitcoin data
directories, that's probably the best.

not trying to test anything specifically, just codign, building, launching
over and over, would like to make the startup of the Qt client faster.
