`apply.c:read_old_data():2340` that\n`git apply without --index/cached\nshould never look at the index because the target file may not be in\nthe index yet\nand we may not be in a Git repository.`\nSo NULL is passed to convert_to_git() in place of `istate`.\n\nSo when we do\n`git apply patch.file` `istate` is NULL, but when we do\n`git apply --cached patch.file`, `istate` is not NULL.\n\nBello\n"},{"id":"533050","messageId":"a881499d-e236-4f8e-a217-b6bce69e3e3c@gmail.com","threadId":"64647","inReplyTo":"aVfzMsN2ouY3UBFG@ubuntu","subject":"Re: [Outreachy PATCH v2] environment:

If we know the set of things we parse early and have a\nway to say \"this command only X, Y, and Z matters (but not W)\", then\nthe above cat-file example can omit the attributesFile from the \"we\ncare\" set.\n\nI think overusing repo_settings is a disease. Moving a singleton\nglobal to per repository (by adding to struct repository) is one\nthing and it is very welcome. But changing the way configuration\nvariables are parsed (e.g., what used to be parsed by only those who\ncare about is now parsed by everybody, or vice versa) needs to be\nhandled carefully.\n"},{"id":"533087","messageId":"xmqqwm1vk83a.fsf@gitster.g","threadId":"64647","inReplyTo":"3947f777-e08a-4c17-81e3-c4711fe666a0@gmail.com","subject":"Re: [Outreachy PATCH v2] environment: move \"core.attributesFile\" into repo-setting","fromName":"Junio C Hamano","fromEmail":"gitster@pobox.com","sentAt":"2026-01-05T22:28:25Z","receivedAt":"2026-01-05T22:28:27Z","isPatch":true,"sender":{"key":"gitster@pobox.com","avatar":"https://avatars.githubusercontent.com/u/54884?v=4"},"body":"Phillip Wood writes:\n\n> On 05/01/2026 14:23, Phillip Wood wrote:\n>> \n>> It is quite common that moving from parsing config settings eagerly by \n>> calling repo_config() at startup to parsing them lazily via 'stuct \n>> repo_settings' causes regressions like this.

It is not \njust rebase that is affected, for example \"git merge\" in a partial clone \nnow downloads all the blobs it wants before erroring out which isn't \nterrible but it is hard to argue that's an improvement.

Given \nhow widespread the use of attributes is it would be hard to audit all \nthe affected code paths and adjust them to the new behavior.\n\n>> It is quite common that moving from parsing config settings eagerly by\n>> calling repo_config() at startup to parsing them lazily via 'stuct\n>> repo_settings' causes regressions like this.

We'd \nalso need to be careful to update the list when adding new features \nwhich depended on config variables that were not previously used by that \ncommand.\n\n> I think overusing repo_settings is a disease.

It would certainly be \nbetter if we can find a solution that uses the repository passed to \ncommand when it is non-NULL. Unfortunately commands like \"git diff \n--no-index\" are passed a NULL repository but we have chosen to store our \nconfig in a `struct repository` and so we need some kind of fake \nrepository for those commands. If we stored our config in a separate \nstruct we wouldn't need to fake a repository but then we'd have to pass \nthe config round separately to the repository which is a pain. Perhaps \ngit_default_config() could use `the_repository` when it's given a NULL \npointer for the callback data.\n\nThanks\n\nPhillip\n\n"},{"id":"533222","messageId":"8899016f-eeef-404b-8da6-ff3a90e81cea@gmail.com","threadId":"64647","inReplyTo":"922629dc-828c-4bdf-939c-b38b7b59e8e8@gmail.com","subject":"Re: [Outreachy PATCH v2] environment: move \"core.attributesFile\" into repo-setting","fromName":"Phillip Wood","fromEmail":"phillip.wood123@gmail.com","sentAt":"2026-01-07T14:18:57Z","receivedAt":"2026-01-07T14:19:07Z","isPatch":true,"sender":{"key":"phillip.wood@dunelm.org.uk","avatar":null},"body":"On 07/01/2026 10:26, Phillip Wood wrote:\n> On 06/01/2026 13:44, Bello Olamide wrote:\n>>\n>> But won't this be a temporary solution since the goal is to prevent \n>> the use of\n>> `the_repository`?\n> \n> Yes but it would be a good start as passing a repository down to \n> git_default_config() will be quite invasive.\n\nTo expand on this the first steps could be\n (i) create a new struct to hold the config settings from\n git_default_config()\n (ii) add that struct as a member of `struct repository`\n(iii) one-by-one, for each setting parsed by git_default_config() add a\n new member to the config struct, store the parsed value in\n `the_repository` and adjust any code that uses the variable.\n\nThen later we can tackle the intrusive change to pass a `struct \nrepository` down to git_default_config() and store the settings in that \nrather than `the_repository`.
