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

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

Merge branch 'jk/unused-fixes'

2022-08-29T21:55:12Z

Code clean-up to remove unused function parameters. * jk/unused-fixes: xdiff: drop unused mmfile parameters from xdl_do_patience_diff() reflog: assert PARSE_OPT_NONEG in parse-options callbacks reftable: drop unused parameter from reader_seek_linear() verify_one_sparse(): drop unused parameters match_pathname(): drop unused "flags" parameter log-tree: drop unused commit param in remerge_diff() xdiff: drop unused mmfile parameters from xdl_do_histogram_diff()

log-tree: drop unused commit param in remerge_diff()

2022-08-19T19:20:43Z

This function has never used its "commit" parameter since it was added in db757e8b8d (show, log: provide a --remerge-diff capability, 2022-02-02). This makes sense; we already have separate parameters for the parents (which lets us redo the merge) and the oid of the result tree (which we can then diff against the remerge result). Let's drop the unused parameter in the name of clarity. 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

log-tree: use ref_namespaces instead of if/else-if

2022-08-05T21:13:12Z

The add_ref_decoration() method uses an if/else-if chain to determine if a ref matches a known ref namespace that has a special decoration category. That decoration type is later used to assign a color when writing to stdout. The newly-added ref_namespaces array contains all namespaces, along with information about their decoration type. Check this array instead of this if/else-if chain. This reduces our dependency on string literals being embedded in the decoration logic. Signed-off-by: Derrick Stolee Signed-off-by: Junio C Hamano

refs: use ref_namespaces for replace refs base

2022-08-05T21:13:12Z

The git_replace_ref_base global is used to store the value of the GIT_REPLACE_REF_BASE environment variable or the default of "refs/replace/". This is initialized within setup_git_env(). The ref_namespaces array is a new centralized location for information such as the ref namespace used for replace refs. Instead of having this namespace stored in two places, use the ref_namespaces array instead. For simplicity, create a local git_replace_ref_base variable wherever the global was previously used.
