git/submodule.c, branch v2.38.4

Merge branch 'ab/unused-annotation'

2022-09-14T19:56:39Z

Undoes 'jk/unused-annotation' topic and redoes it to work around Coccinelle rules misfiring false positives in unrelated codepaths. * ab/unused-annotation: git-compat-util.h: use "deprecated" for UNUSED variables git-compat-util.h: use "UNUSED", not "UNUSED(var)"

Merge branch 'jk/unused-annotation'

2022-09-14T19:56:39Z

Annotate function parameters that are not used (but cannot be removed for structural reasons), to prepare us to later compile with -Wunused warning turned on. * jk/unused-annotation: is_path_owned_by_current_uid(): mark "report" parameter as unused run-command: mark unused async callback parameters mark unused read_tree_recursive() callback parameters hashmap: mark unused callback parameters config: mark unused callback parameters streaming: mark unused virtual method parameters transport: mark bundle transport_options as unused refs: mark unused virtual method parameters refs: mark unused reflog callback parameters refs: mark unused each_ref_fn parameters git-compat-util: add UNUSED macro

submodule API: don't handle SM_..{UNSPECIFIED,COMMAND} in to_string()

2022-09-02T16:16:24Z

Change the submodule_strategy_to_string() function added in 3604242f080 (submodule: port init from shell to C, 2016-04-15) to really return a "const char *". In the "SM_UPDATE_COMMAND" case it would return a strbuf_detach(). Furthermore, this function would return NULL on SM_UPDATE_UNSPECIFIED, so it wasn't safe to xstrdup() its return value in the general case, or to use it in a sprintf() format as the code removed in the preceding commit did. But its callers would never call it with either SM_UPDATE_UNSPECIFIED or SM_UPDATE_COMMAND. Let's have its behavior reflect how its only user expects it to behave, and BUG() out on the rest. By doing this we can also stop needlessly xstrdup()-ing and free()-ing the memory for the config we're setting. We can instead always use constant strings. We can also use the *_tmp() variant of git_config_get_string(). Let's also rename this submodule_strategy_to_string() function to submodule_update_type_to_string(). Now that it's only tasked with returning a string version of the "enum submodule_update_type type". Before it would look at the "command" field in "struct submodule_update_strategy".

git-compat-util.h: use "UNUSED", not "UNUSED(var)"

2022-09-01T17:49:48Z

As reported in [1] the "UNUSED(var)" macro introduced in 2174b8c75de (Merge branch 'jk/unused-annotation' into next, 2022-08-24) breaks coccinelle's parsing of our sources in files where it occurs. Let's instead partially go with the approach suggested in [2] of making this not take an argument. As noted in [1] "coccinelle" will ignore such tokens in argument lists that it doesn't know about, and it's less of a surprise to syntax highlighters. This undoes the "help us notice when a parameter marked as unused is actually use" part of 9b240347543 (git-compat-util: add UNUSED macro, 2022-08-19), a subsequent commit will further tweak the macro to implement a replacement for that functionality. 1. https://lore.kernel.org/git/220825.86ilmg4mil.gmgdl@evledraar.gmail.com/ 2. https://lore.kernel.org/git/220819.868rnk54ju.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

config: mark unused callback parameters

2022-08-19T19:18:55Z

The callback passed to git_config() must conform to a particular interface. But most callbacks don't actually look at the extra "void *data" parameter. Let's mark the unused parameters to make -Wunused-parameter happy. Note there's one unusual case here in get_remote_default() where we actually ignore the "value" parameter. That's because it's only checking whether the option is found at all, and not parsing its value. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

refs: mark unused each_ref_fn parameters

2022-08-19T19:18:54Z

Functions used with for_each_ref(), etc, need to conform to the each_ref_fn interface. But most of them don't need every parameter; let's annotate the unused ones to quiet -Wunused-parameter. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

Merge branch 'ab/leakfix'

submodule.c: free() memory from xgetcwd()

2022-07-01T18:43:42Z

Fix a memory leak in code added in bf0231c6614 (rev-parse: add --show-superproject-working-tree, 2017-03-08), we should never have made the result of xgetcwd() a "const char *", as we return a strbuf_detach()'d value. Let's fix that and free() it when we're done with it. We can't mark any tests passing passing with SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true" as a result of this change, but e.g. "t/t1500-rev-parse.sh" now gets closer to passing.

submodule--helper: rename "absorb-git-dirs" to "absorbgitdirs"

2022-06-28T20:13:17Z

Rename the "absorb-git-dirs" subcommand to "absorbgitdirs", which is what the "git submodule" command itself has called it since the subcommand was implemented in f6f85861400 (submodule: add absorb-git-dir function, 2016-12-12). Having these two be different will make it more tedious to dispatch to eventually dispatch "git submodule--helper" directly, as we'd need to retain this name mapping. So let's get rid of this needless inconsistency. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano
