Subject: nested submodules detection w/o .gitmodules file
Date: Sun, 22 Jan 2023 23:34:03 +0300 [thread overview]
Message-ID: <1716310675.20230122233403@inbox.ru> (raw)
Hello Git,
I have a pretty long investigation has been started from usage 3dparty projects related directly or indirectly to the git submodules:
`svn externals replacement` : https://github.com/chronoxor/gil/issues/6
`svn complete replacement for externals` : https://github.com/dirk-thomas/vcstool/issues/243
And stumbled on this discussion:
`nested submodules detection w/o .gitmodules file` : https://github.com/gitextensions/gitextensions/discussions/10644 (https://github.com/gitextensions/gitextensions/issues/10642)
The main question here is that, could the git have has submodules without `.submodules` file?
If no, then all side projects which utilizes it's own input file for the externals may subsequentially fail:
https://github.com/chronoxor/gil
https://github.com/dirk-thomas/vcstool
https://github.com/ingydotnet/git-subrepo
If yes, then other projects which does rely on the `.submodules` would have not actual or even invalid state:
https://github.com/gitextensions/gitextensions
Or even the github itself:
`Zip archive to include submodule` : https://github.com/dear-github/dear-github/issues/214
(`[PATCH] archive: add –recurse-submodules to git-archive command` : https://git.github.io/rev_news/2022/11/30/edition-93/, https://lore.kernel.org/git/pull.1359.git.git.1665597148042.gitgitgadget@gmail.com/)
Mine point here is that:
Git database is a primary storage. The `.gitmodules` file is not a primary storage, so can be in not an actual or desync state with the database.
And any application or a 3dparty project must read the database directly.
But another problem here is that the git still does not have a stable API for that.
For example, a submodule can be declared directly from the `.git/config` file in a working copy:
https://git-scm.com/docs/git-submodule#Documentation/git-submodule.txt-init--ltpathgt82308203
https://git-scm.com/docs/gitsubmodules#_active_submodules
So, who is right and what is wrong here?
