Subject: [PATCH v5 0/9] Make submodules work if .gitmodules is not checked out
Date: Mon, 17 Sep 2018 16:09:31 +0200
Message-ID: <20180917140940.3839-1-ao2@ao2.it> (raw)

Hi,

this series teaches git to try and read the .gitmodules file from the
index (:.gitmodules) or from the current branch (HEAD:.gitmodules) when
the file is not readily available in the working tree.

This can be used, together with sparse checkouts, to enable submodule
usage with programs like vcsh[1] which manage multiple repositories with
their working trees sharing the same path.

v4 of the series is here:
https://public-inbox.org/git/20180824132951.8000-1-ao2@ao2.it/

v3 of the series is here:
https://public-inbox.org/git/20180814110525.17801-1-ao2@ao2.it/

v2 of the series is here:
https://public-inbox.org/git/20180802134634.10300-1-ao2@ao2.it/

v1 of the series, with some background info, is here:
https://public-inbox.org/git/20180514105823.8378-1-ao2@ao2.it/

v5 only contains some small cosmetic fixes suggested by Ævar Arnfjörð
Bjarmason, I ignored the comment about the memory leak in patch
1 because I think there is no leak in how git_config_parse_key is used:
https://public-inbox.org/git/87wosfesxl.fsf@evledraar.gmail.com/

Changes since v4:

  * Improve names of local variables in patch 1.

  * Move new functions definitions in patches 1 and 2 before
    a pre-existing comment instead of after it, as the comment does not
    apply to the new functions.

I am repeating the previous changelog below for your convenience, as v3
is what is currently in pu/ao/submodule-wo-gitmodules-checked-out.

Changes between v3 and v4:

  * Improve robustness of current tests in t7411-submodule-config.sh:
      - merge two tests that check for effects of the same commit.
      - reset to a well defined point in history when exiting the tests.

  * Fix style issues in new tests added to t7411-submodule-config.sh:
      - use test_when_finished in new tests.
      - name the output file 'expect' instead of 'expected'.

  * Add a new "submodule--helper config --check-writeable" command.

  * Use "s--h config --check-wrteable" in git-submodule.sh to share the
    code with the C implementation instead of duplicating the safety
    check in shell script.

  * Add the ability to read .gitmodules from the index and then
    fall-back to the current branch if the file is not in the index.
    Add also more tests to validate all the possible scenarios.

  * Fix style issues in t7416-submodule-sparse-gitmodules.sh:
      - name the output file 'expect' instead of 'expected'.
      - remove white space after the redirection operator.
      - indent the HEREDOC block.
      - use "git -C super" instead of a subshell when there is only one
        command in the test.

  * Remove a stale file named 'new' which erroneously slipped in
    a commit.

  * Update some comments and commit messages.


Thank you,
   Antonio
