packfile: pass down repository to `for_each_packed_object`

2024-12-03T23:21:54Z

The function `for_each_packed_object` currently relies on the global variable `the_repository`. To eliminate global variable usage in `packfile.c`, we should progressively shift the dependency on the_repository to higher layers. Let's remove its usage from this function and closely related function `is_promisor_object`. Signed-off-by: Karthik Nayak Signed-off-by: Junio C Hamano

builtin/refs: add verify subcommand

2024-08-08T16:36:53Z

Introduce a new subcommand "verify" in git-refs(1) to allow the user to check the reference database consistency and also this subcommand will be used as the entry point of checking refs for "git-fsck(1)". Add "verbose" field into "fsck_options" to indicate whether we should print verbose messages when checking refs and objects consistency. Remove bit-field for "strict" field, this is because we cannot take address of a bit-field which makes it unhandy to set member variables when parsing the command line options. The "git-fsck(1)" declares "fsck_options" variable with "static" identifier which avoids complaint by the leak-checker. However, in "git-refs verify", we need to do memory clean manually. Thus add "fsck_options_clear" function in "fsck.c" to provide memory clean operation.

fsck: add refs report function

2024-08-08T16:36:52Z

Introduce a new struct "fsck_ref_report" to contain the information we need when reporting refs-related messages. With the new "fsck_vreport" function, add a new function "fsck_report_ref" to report refs-related fsck error message. Unlike "report" function uses the exact parameters, we simply pass "struct fsck_ref_report *report" as the parameter. This is because at current we don't know exactly how many fields we need. By passing this parameter, we don't need to change this function prototype when we want to add more information into "fsck_ref_report". We have introduced "fsck_report_ref" function to report the error message for refs. We still need to add the corresponding callback function. Create refs-specific "error_func" callback "fsck_refs_error_function". Last, add "FSCK_REFS_OPTIONS_DEFAULT" macro to create default options when checking ref consistency.

fsck: add a unified interface for reporting fsck messages

2024-08-08T16:36:52Z

The static function "report" provided by "fsck.c" aims at checking error type and calling the callback "error_func" to report the message. Both refs and objects need to check the error type of the current fsck message. In order to extract this common behavior, create a new function "fsck_vreport". Instead of using "...", provide "va_list" to allow more flexibility. Instead of changing "report" prototype to be align with the "fsck_vreport" function, we leave the "report" prototype unchanged due to the reason that there are nearly 62 references about "report" function. Simply change "report" function to use "fsck_vreport" to report objects related messages.

fsck: make "fsck_error" callback generic

2024-08-08T16:36:52Z

The "fsck_error" callback is designed to report the objects-related error messages. It accepts two parameter "oid" and "object_type" which is not generic. In order to provide a unified callback which can report either objects or refs, remove the objects-related parameters and add the generic parameter "void *fsck_report". Create a new "fsck_object_report" structure which incorporates the removed parameters "oid" and "object_type". Then change the corresponding references to adapt to new "fsck_error" callback.

fsck: rename objects-related fsck error functions

2024-08-08T16:36:52Z

The names of objects-related fsck error functions are generic. It's OK when there is only object database check. However, we are going to introduce refs database check report function. To avoid ambiguity, rename object-related fsck error functions to explicitly indicate these functions are used to report objects-related messages.

fsck: rename "skiplist" to "skip_oids"

2024-08-08T16:36:52Z

The "skiplist" field in "fsck_options" is related to objects. Because we are going to introduce ref consistency check, the "skiplist" name is too general which will make the caller think "skiplist" is related to both the refs and objects. It may seem that for both refs and objects, we should provide a general "skiplist" here. However, the type for "skiplist" is `struct oidset` which is totally unsuitable for refs. To avoid above ambiguity, rename "skiplist" to "skip_oids". Mentored-by: Patrick Steinhardt Mentored-by: Karthik Nayak Signed-off-by: shejialuo Signed-off-by: Junio C Hamano

oidset: pass hash algorithm when parsing file

2024-06-14T17:26:34Z

The `oidset_parse_file_carefully()` function implicitly depends on `the_repository` when parsing object IDs. Fix this by having callers pass in the hash algorithm to use. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano
