...starting from a template (aka configuration file), and using the
variables defined via a ["CC/auto", "config"] target.
For example, to use a CMake configuration file, the targets could be
defined as follows
...
, "foo-header-blueprint":
{ "type": ["@", "rules", "CC/auto", "config_file"]
, "input": ["config.hpp.in"]
, "output": ["config.hpp"]
, "stage": ["foo"]
, "magic_string": ["cmakedefine"]
, "@only": ["true"]
}
, "foo-header":
{ "type": "configure"
, "target": "foo-header-blueprint"
, "config":
{ "type": "let*"
, "bindings":
[ [ "defines"
, [ ["var", "\"string value\""]
, ["FOO_MAJOR_VERSION", "3"]
, ["use_this_feature", true]
]
]
]
, "body": {"type": "env", "vars": ["defines"]}
}
}
...
The file config.hpp.in may look as follows
#ifndef config_cmake
#define config_cmake
#cmakedefine var
#cmakedefine use_this_feature
#cmakedefine01 use_this_feature
#cmakedefine unused
#define FOO_VERSION @FOO_MAJOR_VERSION@
#define DONT_TOUCH_THIS ${FOO_MAJOR_VERSION}
#endif
and the generated configuration file foo/config.hpp is
#ifndef config_cmake
#define config_cmake
#define var "string value"
#define use_this_feature
#define use_this_feature 1
/* #undef unused */
#define FOO_VERSION 3
#define DONT_TOUCH_THIS ${FOO_MAJOR_VERSION}
#endif

google::longrunning::Operations::GetOperation
For each action that is executed, an entry is added to a shared thread
safe cache. Once the number of operations stored exceeds twice 2^n,
where n is given by the option --log-operations-threshold, at most 2^n
operations will be removed, in a FIFO scheme.

Main updates to build description:
- remove unused defines of type "HAVE_<lib>_H"
- add new variables that allow users to set explicitly the presence of some lib symbols
- replace most defines of type "HAVE_<lib>" with "USE_<lib>" (to match the flag names)
- added GLOBs (where it made sense) for increased maintainability
|
|
Changes in build description:
- fix capitalization of ENABLE_LIBGCC flag.
- add new HIDE_SYMBOLS flag to allow hiding of export symbols; used
similar logic as for libcurl to circumvent the original
CHECK_C_SOURCE_COMPILES macro use.
|
|
Changes to build description:
- new USE_SHA256 flag
- removed "Generic" option for USE_SHA1
- updated to the new source code structure
(split "src/git2" into "src/libgit2" and "src/util")

... while following symbolic links. In this way, bootstrapping
is possible against preinstalled dependencies that symbolic links
or special files in their directories.

...as it is consumed by both grpc and libcurl. This makes sure
that both those libraries see the same ares target.
|
|
... by using an explicit tree reference.

A lot of the dependencies in the "just" repository are not for
building just itself, but are used the the just-mr tool or for
testing. As the bootstrap process, however, only bootstraps the just
tool itself, drop those dependencies from the bootstrap process.

Both ["", "ssl"] and ["", "crypto"] are targets of "boringssl"
that are intended for use outside this repository. Both depend on
the ["CC", "library"]-target ["", "crytpo-lib"], in fact even visibly,
as ssl has a library-dependency on the crypto library. Therefore,
we have to follow the standard export pattern that all uses of this
library go through the same (closest) export target. Fix this!

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
|
|
... in favor of the "tree" built-in rule.

In our packaging of git2, do not carry out a configuration transition
that is visible to dependencies. While its dependencies, ssl and
zlib, accept that TARGET_ARCH is defaulted to ARCH if unset and
still return the same result, regardless which export targets are
cached, we still should not enforce any configuration transition on
dependencies as this has the potential to cause subtle conflicts.
The implicit default of TARGET_ARCH to ARCH in zlib and ssl can
stay, as those libraries do not depend on any other repositories.
|
|
And in this way avoid that two configuration differing only in an
unset TARGET_ARCH set to ARCH can be different due to one configration
being in target-level cache, but not the other.
|
|
In this way, we achieve that the target to be used by targets outside
this repository is the same, regardless if an unset TARGET_ARCH
is replaced by the value of ARCH. This is an assumption consuming
targets (legitimately) make and that was violated if one of those
configs is in target-level cache, but not the other.
|
|
|
|
In this way, they can be more easily found using the standard
just-mr --main com_github_libgit2_libgit2 describe '' git2
instead of searching for the documentation file next to the
targets files in the import directory.

... in the same way, as we support different names for cc and c++.
|

... also in the first phases of the bootstrap procedure.
