Merge branch 'ts/unpacklimit-config-fix' into maint-2.42

2023-11-02T07:53:16Z

transfer.unpackLimit ought to be used as a fallback, but overrode fetch.unpackLimit and receive.unpackLimit instead. * ts/unpacklimit-config-fix: transfer.unpackLimit: fetch/receive.unpackLimit takes precedence

transfer.unpackLimit: fetch/receive.unpackLimit takes precedence

2023-08-23T01:30:49Z

The transfer.unpackLimit configuration variable is documented to be used only as a fallback value when the more operation-specific fetch.unpackLimit and receive.unpackLimit variables are not set, but the implementation had the precedence reversed. Apparently this was broken since the transfer.unpackLimit was introduced in e28714c5 (Consolidate {receive,fetch}.unpackLimit, 2007-01-24). Often when documentation and code have diverged for so long, we prefer to change the documentation instead, to avoid disrupting users. But doing so would make these weirdly unlike most other "specific overrides general" config options. And the fact that the bug has existed for so long without anyone noticing implies to me that nobody really tries to mix and match them much.

git-compat-util: move alloc macros to git-compat-util.h

2023-07-05T18:42:31Z

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for dynamic array allocation. Moving these macros to git-compat-util.h with the other alloc macros focuses alloc.[ch] to allocation for Git objects and additionally allows us to remove inclusions to alloc.h from files that solely used the above macros.

config: add ctx arg to config_fn_t

2023-06-28T21:06:39Z

Add a new "const struct config_context *ctx" arg to config_fn_t to hold additional information about the config iteration operation. config_context has a "struct key_value_info kvi" member that holds metadata about the config source being read (e.g. what kind of config source it is, the filename, etc). In this series, we're only interested in .kvi, so we could have just used "struct key_value_info" as an arg, but config_context makes it possible to add/adjust members in the future without changing the config_fn_t signature. We could also consider other ways of organizing the args (e.g. moving the config name and value into config_context or key_value_info), but in my experiments, the incremental benefit doesn't justify the added complexity (e.g. a config_fn_t will sometimes invoke another config_fn_t but with a different config value). In subsequent commits, the .kvi member will replace the global "struct config_reader" in config.c, making config iteration a global-free operation. It requires much more work for the machinery to provide meaningful values of .kvi, so for now, merely change the signature and call sites, pass NULL as a placeholder value, and don't rely on the arg in any meaningful way. Most of the changes are performed by contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every config_fn_t: - Modifies the signature to accept "const struct config_context *ctx" - Passes "ctx" to any inner config_fn_t, if needed - Adds UNUSED attributes to "ctx", if needed Most config_fn_t instances are easily identified by seeing if they are called by the various config functions. Most of the remaining ones are manually named in the .cocci patch. Manual cleanups are still needed, but the majority of it is trivial; it's either adjusting config_fn_t that the .cocci patch didn't catch, or adding forward declarations of "struct config_context ctx" to make the signatures make sense. The non-trivial changes are in cases where we are invoking a config_fn_t outside of config machinery, and we now need to decide what value of "ctx" to pass. These cases are: - trace2/tr2_cfg.c:tr2_cfg_set_fl() This is indirectly called by git_config_set() so that the trace2 machinery can notice the new config values and update its settings using the tr2 config parsing function, i.e. tr2_cfg_cb(). - builtin/checkout.c:checkout_main() This calls git_xmerge_config() as a shorthand for parsing a CLI arg. This might be worth refactoring away in the future, since git_xmerge_config() can call git_default_config(), which can do much more than just parsing. Handle them by creating a KVI_INIT macro that initializes "struct key_value_info" to a reasonable default, and use that to construct the "ctx" arg.

object-store-ll.h: split this header out of object-store.h

2023-06-21T20:39:54Z

The vast majority of files including object-store.h did not need dir.h nor khash.h. Split the header into two files, and let most just depend upon object-store-ll.h, while letting the two callers that need it depend on the full object-store.h. After this patch: $ git grep -h include..object-store | sort | uniq -c 2 #include "object-store.h" 129 #include "object-store-ll.h" Diff best viewed with `--color-moved`.

repository: remove unnecessary include of path.h
