2021-07-01*.c *_init(): define in terms of corresponding *_INIT macroLibravatar Ævar Arnfjörð Bjarmason1-3/+2
Change the common patter in the codebase of duplicating the initialization logic between an *_INIT macro and a corresponding *_init() function to use the macro as the canonical source of truth. Now we no longer need to keep the function up-to-date with the macro version. This implements a suggestion by Jeff King who found that under -O2 [1] modern compilers will init new version in place without the extra copy[1]. The performance of a single *_init() won't matter in most cases, but even if it does we're going to be producing efficient machine code to perform these operations. 1. https://lore.kernel.org/git/YNyrDxUO1PlGJvCn@coredump.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-07-30strvec: rename struct fieldsLibravatar Jeff King1-22/+22
The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

2020-07-28strvec: rename files from argv-array to strvecLibravatar Jeff King1-0/+109
This requires updating #include lines across the code-base, but that's all fairly mechanical, and was done with: git ls-files '*.c' '*.h' | xargs perl -i -pe 's/argv-array.h/strvec.h/' Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
