This is a tweaked version of pull request #2106 that will cross-compile on Lucid, so it is (I hope!) compatible with the pull-tester and our old gitian-building environment.
I've been testing this versus the boost-based, old-leveldb code in git HEAD.
So this doesn't include the switch to Boost 1.52 and even doesn't rely on the static switches?
Test results, on a Windows XP SP3 virtual machine:
Memory usage: 570MB peak during initial block download ~300MB typical usage during IBD ~200MB peak usage restarting fully synced
Import native Windows LevelDB port by Hiram Chirino.
Extracted from from https://github.com/chirino/leveldb.git using
git diff dd0d562..aea83b7
Several changes to make the native windows leveldb code compile
with mingw32 and run on 32-bit Windows:
* Remove -std=c++0x dependency (modified code to use NULL instead of
nullptr)
* Link with -lshlwapi
* Only #define snprintf/etc if compiling with Visual Studio
* Do not link against DbgHelp.lib (wrote a CreateDir instead of using
DbgHelp's MakeSureDirectoryPathExists
* Define WINVER=0x0500 so MinGW32 can use the 64-bit-filesystem Windows
api calls
* Define __USE_MINGW_ANSI_STDIO=1 to use MinGW's printf (which supports
%ll)
I also cleaned up makefile.mingw, assuming that dependencies would be in
the standard /usr/local/{include,lib} by default but allowing overriding
with make DEPSDIR=... etc
