Describe the issue

Program ignore disk space limitation, what i set up on start

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

  1. start bitcoin-0.14.2/bin/bitcoin-qt
  2. select checkbox what you want to limit data to 1024Mb (~6 days)
  3. bitcoin use all disk space (~16Gb in my case) and throws an error.

Expected behaviour

Program syncing a blockchain using only 1Gb of free space on my hdd

Actual behaviour

Even if i selected to limit disk space to 1024Mb, program used all available space. folder .bitcoin/blocks/have size of 16Gb.

What version of Bitcoin Knots are you using?

bitcoin-0.14.2.knots20170618-x86_64-linux-gnu.tar.gz

Machine specs:

Any extra information that might be useful in the debugging process.

There is no bitcoin_rw.conf file (not in .bitcoin folder and not in ~/.config/Bitcoin) there is only Bitcoin-Qt.conf file:

Sorry, your theme made me think you were using Mac.

On Linux, the directory is ~/.bitcoin

There should be a bitcoin_rw.conf file in it...

That's odd. Are you setting $HOME or -datadir when you run Bitcoin Knots? Why is it using ~/patatipatata/0_btc/ for the .bitcoin directory?

@nikitasius

nope, i should?

clean run:

  1. i downloaded https://bitcoinknots.org/files/0.15.x/0.15.0.knots20170914/bitcoin-0.15.0.knots20170914-x86_64-linux-gnu.tar.gz
  2. i unpacked it into ~/patatipatata/0_btc/
  3. i open terminal in ~/patatipatata/0_btc/bitcoin-0.15.0/bin
  4. i run ./bitcoin-qt

next i setup as

Had to reorganize the code a bit. It was trying to set the prune value before it determined the datadir. So I made it wait to write it until later.

Final fix will be released in 0.15.1. Until then, the custom build is needed for the first-time run only - once it's set correctly, you can use the normal 0.15.0 release.

  Add initialization order fiasco detection in Travis :)

  Context: bitcoin#17670 (comment)

  This would have caught the `events_hasher` initialization order issue introduced in bitcoin#17573  and fixed in bitcoin#17670.

…-overflow

The previous commit added a test which would fail the
unsigned-integer-overflow sanitizer. The warning is harmless and can be
triggered on any commit, since the code was introduced.

For reference, the warning would happen when the separator `-` was not
present.

For example:

  GET /rest/getutxos/6a297bfa5cb8dd976ab0207a767d6cbfaa5e876f30081127ec8674c8c52b16c0_+1.json

would result in:
