Right after project() which contains the version, so that version +
motto updates are basically in one place (and so that non-Makefile cmake
invocations get it).
CMake will set version variables itself if you give the version in the
project(), which is cleaner. Also removes some (nearly) duplicate
definitions and settings added in basic_definitions.cmake for unknown
reasons.
Removes some redundant settings (name, description, version) from the
cpack settings which already default to the values from the project()
call.
* update travis ci clang-format to clang-format-9 because we use that now
add python3-dev package becuase something inside ci thinks it has python but really does not
* try using python3.6
* try working around hot garbage that is travis-ci
* add deadsnakes repo for python3.8
* prevent nullptr deference when running in unit tests
* move python3.8 to main dependancy matrix and add python3.8 to homebrew deps
* add deadsnake apt repo
* add deadsnakes and python3.8 back to previous matrix
* dev package for python
* toggle hive build in ci
* dont add pybind11 if not bulding hive
* revert setting pyenv shim for travis ci
* make native builds on by default except for windows ci
* only apply native build being off for windows release target becuase that broke macos
Howard Hinnart's date.h is the library that was accepted as C++20
date/calendar support, so this is essentially a backport of C++20 date
time support.
(It does support timezone support, but requires more of the library and
that seems like overkill for what we need; this just prints UTC
timestamps instead, which need only a header-only include).
Step 1 of removing abseil from lokinet.
For the most part this is a drop-in replacement, but there are also a
few changes here to the JSONRPC layer that were needed to work around
current gcc 10 dev snapshot:
- JSONRPC returns a json now instead of an optional<json>. It doesn't
make any sense to have a json rpc call that just closes the connection
with returning anything. Invoked functions can return a null (default
constructed) result now if they don't have anything to return (such a
null value won't be added as "result").
Our current abseil won't build with gcc 10 (its `optional`
implementation appears broken), and spews warnings under slightly older
compilers; updating to the latest stable 2019 branch fixes both issues.
We currently spend a bunch of time setting CRYPTO_FLAGS and then just
completely wipe it out if NATIVE_BUILD is specified.
The AMD_RYZEN_HACK is really not needed; it was only some early CPU
microcode and compiler combinations that had trouble detecting Ryzen's
FMA3 support (and Ryzen *doesn't* properly support FMA4--it can be
forced on and runs, but apparently it can give wrong results).
Tuning to an ancient architecture doesn't make a lot of sense; we want
to support the ancient architecture, but don't want to optimize for it.
Also change the AVX2 tuning to use haswell so that optimizations don't
depend on the CPU in the system the build runs on.
