99e7075 Break circular dependency main ↔ txdb (Wladimir J. van der Laan)
|
|
Bitwise logic combined with `<` with undefined signedness will
potentially results in undefined behavior. Fix this by defining the type
as a c++11 typed enum.
Fixes #6017.

Break the circular dependency between main and txdb by:
- Moving `CBlockFileInfo` from `main.h` to `chain.h`. I think this makes
sense, as the other block-file stuff is there too.
- Moving `CDiskTxPos` from `main.h` to `txdb.h`. This type seems
specific to txdb.
- Pass a functor `insertBlockIndex` to `LoadBlockIndexGuts`. This leaves
it up to the caller how to insert block indices.

Inspired by former implementations by Eric Lombrozo and Rusty Russell, and
based on code by Jorge Timon.

A lot of times, disk corruption problems appear here.
To facilitate debugging and troubleshooting, add position information
to the error messages.
|
|
Also add conversion from/to uint256 where needed.
|
|
Replace x=0 with .SetNull(),
x==0 with IsNull(), x!=0 with !IsNull().
Replace uses of uint256(0) with uint256().

Lots of files ended up with indirect includes from script.h.

Many changes:
* Do not use 'getblocks', but 'getheaders', and use it to build a headers tree.
* Blocks are fetched in parallel from all available outbound peers, using a
limited moving window. When one peer stalls the movement of the window, it is
disconnected.
* No more orphan blocks. At all. We only ever request a block for which we have
verified the headers, and store it to disk immediately. This means that a
disk-fill attack would require PoW.
* Require protocol version 31800 for every peer (released in december 2010).
* No more syncnode (we sync from everyone we can, though limited to 1 during
initial *headers* sync).
* Introduce some extra named constants, comments and asserts.
