... by avoiding reusing temp dirs for execute. While we are
at it, also refactor LocalFetchViaTmpRepo() to create its
own empty temp dirs, that cannot be reused by the caller.

When fetching git repositories, just-mr routinely shells out to
git. In this case, allow the user to specify via "inherit env",
which environment variables from the host environment should be
made available in this action. Typical variables to inherit are
ones providing credentials, like SSH_AUTH_SOCK. As the repository
description specifies the commit that will be taken, and hence the
resulting tree, correctness is not affected by the environement
leaking in here.

...to avoid waiting for the test timeout on an internal error.

Also adds a section in the curl_url test suite.

This way they can be used by 'just serve'.
|
|
Similarly to tarballs, an autodetection option for zip-like
archives is added to enable a unified handling of both traditional
zip and 7zip formats. Thus, for "zip" archives just-mr uses now
this autodetection option.
|
|
Also updates the archive usage tests accordingly.
|
|
|
|
We shouldn't exclude the possibility of receiving uncompressed
tarballs as repositories in just-mr. Therefore, we introduce an
explicit type that performs the autodetection (default behaviour
in just-mr). This is done to also be more in line with our
implementation which allows the granular handling of various
archive types (currently used only for testing purposes).
|
|
Tests for various archive types are by design repetitive and thus
can be streamlined to avoid excessive code duplication. As a
positive consequence, this change also adds previously missing .xz
archive usage checks.

... by creating a file only once the server is ready and waiting
for that file instead of waiting a fixed period of time.

This feature has been introduced with C++20.

...using the new ignore-special tree variant.

...by removing unused subfolders and corresponding redundant checks
in the tests using it. Also fixes misues in tests of the GetSubtree
family of methods.
|
|
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.

...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.

Using "test" in the name of a test target is unnecessary and
adds gratuitous inconsistencies.

In the rare cases that we need to shell out to git, let the user
configure what binary to use. Option resolves in the same way as
the just executable, including allowing it to be set via just-mrrc.
Updates all cases of shelling out to git (fetch and commit update).
Update just-mr and just-mrrc docs accordingly.

...due to limitations in SSH support in libgit2. In this case, we
simply execute 'git ls-remote <repo> [<branch>]' and then parse
the output. Remote interogation requires no local repository, so
it is an asynchronious operation by default.
|
|
...due to limited SSH support in libgit2. In order to allow the
fetches to still be parallel, we execute:
git fetch --no-auto-gc --no-write-fetch-head <repo> [<branch>]
This only fetches the packs without updating any refs, at the slight
cost of sometimes fetching some redundant information, which for our
purposes is practically a non-issue.
(If really needed, a 'git gc' call can be done eventually to try to
compact the fetched packs, although a save in disk space is not
actually guaranteed.)

While for unit tests it is best practice to replicate the layout
of the source tree, for end-to-end tests, this is less so. This
is particularly true, as the distinction between the tests for two
tools is a bit blurry; some tests for just still use just-mr as a
launcher, and, e.g., the fetch test for just-mr uses just to carry
out the garbage collection. Therefore, move all end-to-end tests
together so that we also have a joinded target for precisely the
end-to-end tests.
In this reorganisation also indicate more explicitly which tests are
also available for the bootstrap multi-repo tool. That information
was so far hidden by the fact that in the other directory the tool
dependency would not dispatch on TEST_BOOTSTRAP_JUST_MR.

commit update
Uses the SSL certification utility method to correctly set the
certification check options for the remote URL libgit2 calls.
Due to the fact that remote operations are done via a temporary
repository to allow concurrent work, the correct repository
configuration needs to be interrogated. Thankfully, libgit2
provides a thread safe config snapshot object to be used in
such scenarios.
Also updates the existing GitRepoRemote tests accordingly.

Only tests pertaining to methods not covered in the tests of the
inherited class were added.

...in order to not include unwanted dependencies in just proper.
As the whole other_tools folder is meant to be excluded from
bootstrapping, also remove the bootstrap guards.

As now all remote Git operations in GitRepo require at most just
the branch name, there is no more need to inquire the repository
about branch refspecs.
