This should be more robust in future: we SHA256 all of the deps. For wiregen we prefix with EXPERIMENTAL_FEATURES, since it can effect them. Signed-off-by: Rusty Russell <[email protected]>
Now we use the same Makefile rules for all CSV->C generation. Signed-off-by: Rusty Russell <[email protected]>
We're going to make check-source cover every C file soon. Signed-off-by: Rusty Russell <[email protected]>
We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and ALL_C_HEADERS. Then the toplevel Makefile knows which are autogenerated (by wildcard), so it can have all the rules to clean them or check the source as necessary. Signed-off-by: Rusty Russell <[email protected]>
Now that SHA256STAMP protects us, we can avoid timestamps altogether so we don't get missing builds. Signed-off-by: Rusty Russell <[email protected]>
And rename them so they're not cleared by `make clean`. We leave the old rules in place so old files get cleaned still. Signed-off-by: Rusty Russell <[email protected]>
Signed-off-by: Rusty Russell <[email protected]> Changelog-Changed: Build: we no longer require extra Python modules to build.
``` make: *** No rule to make target 'external/gheap/gheap.h', needed by 'bitcoin/chainparams.o'. Stop. make: *** Waiting for unfinished jobs.... ``` Just simplify the Makefile to make all the external headers we use dependent on submodcheck. Signed-off-by: Rusty Russell <[email protected]>
Otherwise make thinks we're done, and we can get errors. Include primitive code if we abort build halfway and leave .refresh-submodules dir. Signed-off-by: Rusty Russell <[email protected]>
The $(TARGET_DIR) may not exist: use mkdir -p. Signed-off-by: Rusty Russell <[email protected]>
And guard the mako-specific tests with a check instead. Signed-off-by: Rusty Russell <[email protected]>

This tests our instructions in INSTALL.md, which say you only need requirements.txt for development or running tests, not building. Also removes the unused SOURCE_CHECK_ONLY flag. Signed-off-by: Rusty Russell <[email protected]>
It's far less verbose than it used to be! And it's occasionally useful. Signed-off-by: Rusty Russell <[email protected]>

This attempts to checkin all the files which we'd need sophisticated python (I'm looking at you, mako!) to build. That way our documentation, which says you only need to pip3 install stuff, is accurate.
I also did numerous parallel builds from fresh git checkouts, which found several issues.
The final commit switches Travis to not install any of that on the "not running unit tests" cases, which will detect cases I missed.
