As boost testlib is extremely IDE unfriendly, as well as human
unfriendly with lots of macros for basic C++ functions (like methods!!)
this is better for me.
But the real reason is that its just unstable. I get double deletes
on some releases of boost and I'm missing plain features that all
other test frameworks have.
For instance a QCOMPARE shows what is expected vs what we got. Boost
just fails.
In QTestLib I can mark a test as "expect fail" an idea that boost
tried and failed (can easily create false positives).
This change makes the limits be static variables, which means they are
only settable once for a process. The only usecase so far is to use much
smaller limits in testing situations.
Flowee changed in that regtest has to be given on the commandline
allowing different config files for different chains.
So pass the regtest on the commandline.
On all mature operating systems and filesystems creation of a 1GB file
will not actually use that data, only when we start using blocks does
the disk space get used.
As such this is a premature optimization that Core added and I ported to
Flowee which this commit removes.
Additionally, increase the block file size to 1GiB
Duplicate the test_bitcoin file into the common dir,
I hope to remove the original in future.
Make the common dir a new static lib and create a new
qtestlib based unit test out of the old doublespend unit test.
together with blockFinished() as 'commit' this introduces the ability
to modify the in-memory utxo which can be rolled-back with ease.
This allows us to "modify" the utxo while validating a block in an
optimistic manner and only spend extra resources doing a rollback
should the block end up not being Ok.
The new UnspentOutputDatabase classes are only very loosly a database, we
purely register and store unspent outputs there. But unline a DB we don't
allow modification (just insert and delete).
This replaces the coin-db (which was based on leveldb) and as first goal
this gives us a higher level of stability. The level-database was known
to give corruption issues.
Notice that users will need to do a manual reindex on first update.
