Numerical values are used at some places in justbuild: as value for
timeout scaling, as well as by the "range" expression that is used,
e.g., to define repreated test runs. Therefore, improve support
for numerical values by adding basic operations.
|
|
While a foldl is enough to implement a reverse functionality,
adding it as a built in allows doing so in linear time.
|
|
... to obtain from a list of strings a map with those entries
as keys and true as value. In this way, repeated membership tests
in lists can be implemented more efficiently.
|
|
This allows better separation and, in particular, repositories
needed only for tests do not have to be provided for building the
tools. This also better documents which dependencies are only needed
for testing.

tests have been updated accordingly

Compared to the previous commit, the action graphs for just
and its unit tests are unchanged.
- Git hash of action graph for ["",""]:
c6e75f17abd7ffaab6ff9bb725ad67ec0bf6c973
- Git hash of action graph for ["test/buildtool","TESTS"]:
8063dfb3dd7daa9ae01d95c177e14946f785c57e
Refactor:
- "local cflags" to "private-cflags"
- "local defines" to "private-defines"
- "link externals" to "private-ldflags"
- "deps" to "private-deps" for (test) binaries
- "proto" to "private-proto" for binaries
Improvements:
- consistent variable declaration order:
OS, ARCH, HOST_ARCH, TARGET_ARCH,
CC, CXX, CFLAGS, CXXFLAGS, ADD_CFLAGS, ADD_CXXFLAGS,
AR, ENV, PATH
- use fields close to their definition (in RULES)
- use common expression for binaries and test binaries
- split expression "flags" and "compiler"
... to separate ones for CC and CXX.
- rename "transition" to "deps-transition"
... to avoid conflicts with other transitions.
- support "defaults-transition" for CC expressions
Implement:
- "cflags" for libraries
- "private-cflags" for (test) binaries
- "private-defines" for test binaries
- "private-ldflags" for test binaries
- (public) "defines" for libraries

Add a function transforming a list into a map. In this way, artifacts
collected positionally in a list can easily be realized as a stage
used for input to an action or output of a target.
|
|
... and detect conflicts araising this way. Also normalize
the paths after staging them to the specified subdir.
|
|
To concatenate lists (the only ability the "+" operator had),
use "++".
|
|
For historic reasons, we considerd special strings as false values.
Drop that behavior in favor of a clean LISP-like semantics: everything
is true that is not empty.

Given a number or number representation, return a list of that
length consisting of representations of the lower numbers. In this
way, repeated non-pure actions can be generated (e.g., repetitions
of a test to detect flakyness).

This is the initial version of our tool that is able to
build itself. In can be bootstrapped by
./bin/bootstrap.py
