Some of the more specific issues addressed: - missing log_level target/include - header-only libs wrongly marking deps as private - missing/misplaced gsl includes
2023-07-10just-mr: Fix handling of .gitignore files in git repositoriesPaul Cristian Sarbu
The command 'git add .' does not include paths found in .gitignore files in the directory tree where the command is issued. This is not the desired behaviour, as we expect for a tree with a given commit id to contain all of the entries, irrespective of their meaning to Git. This commit addresses the issue as described. For the just-mr.py script we modified the staging command to 'git add -f .'. For the compiled just-mr, simply adding the force flag to 'git_index_add_all' did not work as intended for files found in ignored subdirectories. This is a known libgit2 issue which has been fixed in v1.6.3. Until we can upgrade our libgit2 version, a workaround was implemented: we recursively read the directory entries ourselves and add each of them iteratively using 'git_index_add_bypath', making sure to ignore the root '.git' subtree (which cannot be staged). At the moment the handling of Git submodules remains an open issue, as Git does not allow '.git' subtrees to be forcefully added to the index, and thus such directory entries will currently not be considered as part of a git tree. This however is consistent behavior between Git and libgit2.
2023-06-09Git CAS: report absence of CAS at debug levelKlaus Aehlig
A git CAS ist just a fall back, so it is OK if it is absent (e.g., the specificed directory does not exist). Therefore only log at debug level, not at error level if we cannot open it.

... and in this way, continue to work correctly in the absence of a current working directory.
2023-05-15memcheck: fix race in libgit2...Paul Cristian Sarbu
...caused by incorrectly setting and resetting the library internal state and the misuse of pthreads in libgit2. Normally, git_libgit2_init and git_libgit2_shutdown should span the life of a worker thread in order to be safely used. However, due to an incorrect implementation of libgit2's threadstate with pthreads, on unix systems there is a race condition. Until the use of pthread_key_t is corrected in libgit2, we need to apply a workaround by always ensuring that the main thread is the first thread reaching the GitContext constructor.
2023-04-26imports: Switch to Microsoft GSL implementationOliver Reiche
... with two minor code base changes compared to previous use of gsl-lite: - dag.hpp: ActionNode::Ptr and ArtifactNode::Ptr are not wrapped in gsl::not_null<> anymore, due to lack of support for wrapping std::unique_ptr<>. More specifically, the move constructor is missing, rendering it impossible to use std::vector<>::emplace_back(). - utils/cpp/gsl.hpp: New header file added to implement the macros ExpectsAudit() and EnsureAudit(), asserts running only in debug builds, which were available in gsl-lite but are missing in MS GSL.
2023-03-30GitRepo: Guard fake repository odb wrappingPaul Cristian Sarbu
In the current libgit2 implementation, a fake repository wrapped around an existing odb is being registered as owner the same way as a normal repository object. Therefore, one has to guard both the creation and destruction of the fake repository against all other git operations that might access the internal cache during this transfer of ownership.

...in order to not include unwanted dependencies in just proper. The new class extends the GitRepo class used for just's Git tree operations and gets used in all of just-mr's async maps.
