why:
on 32bit windows 7, there seems to be a 64k memory ceiling for the gcc
compiler which was exceeded on some test platform.
details:
compiling VM2 for low memory C compiler can be triggered with
"make ENABLE_VM2LOWMEM". this comes with a ~24% longer execution time
of the test suite against old VM and optimised VM2.
why:
vm2 enabled by ENABLE_VM2=1 behaves as vm without ENABLE_EVMC=1 until
it doesn't in some future fatch set. this leaves some wiggle room
to work on a vm copy without degrading the original implementation.
details:
+ additional make flag ENABLE_VM2=1 (or ENABLE_VM2=0 to explicitely disable)
+ when both flags ENABLE_EVMC=1 and ENABLE_VM2=1 are present, the former
flag ENABLE_EVMC=1 takes precedence, this is implemented at the NIM
compiler level for -d:evmc_enabled and -d:vm2_enabled
* switch to chronos metrics, remove insecure
See https://github.com/status-im/nimbus-eth2/pull/2468
also fixes pcre linking for real, and adds some random build flags that
help nimbus-eth2 stay afloat
* fix help
* don't omit frame pointers on windows
* bump vendor/nimbus-build-system
- add the Nim compiler header to the Nimbus header
- also support the USE_LIBBACKTRACE env var
* "go-checks" target no longer available
- Travis: switch language
- AppVeyor: disable `mingw32-make go-checks` for now
- `make update`: export GIT_LFS_SKIP_SMUDGE=1
- CI: disable the LFS script inside Makefile,
since we run it separately (and git-lfs is not installed in the Travis
macOS image if we found a valid cache).
- re-enable Nim's cache globally
- add a new "nimcache" subdir for the libraries
- make sure Go doesn't try to link libnimbus.a in the dynamically linked
wrapper example
- always delete the static archive before recreating it
- rename wrapper.nim/.h to libnimbus.nim/.h
- better hygiene in libnimbus.h (include guards and C++ support)
- remove MainnetBootnodes copy, since we do include "config.nim" after all
- moved "nimbus/api" to "wrappers"
- renamed files
- replaced the build scripts with Makefile targets
- set the rpath relative to the test binary's location so it can look
for libnimbus.so there at runtime
- libnimbus.so.0 required on Linux, apparently
- compiled all the Nimbus code with `--app:lib`, not just one file (this
required skipping a proc in "nimbus/config.nim" because it uses an API
that's unavailable in libraries)
- removed static linking from the Go wrapper. It doesn't make sense at a
global level, when using a shared Nimbus library. To selectively link
static libraries, we should probably be specifying them as *.a. I did
build a static libnimbus.a, as a test, but it insisted on dlopen-ing a
shared version of itself which looked too ugly to continue.
