Subject: [PATCH v2 2/2] MacOs: Precompose startup_info->prefix
Date: Sun,  4 Apr 2021 08:17:54 +0200	[thread overview]
Message-ID: <20210404061754.19428-1-tboegi@web.de> (raw)
In-Reply-To: <xmqqtuotfre5.fsf@gitster.g>

From: Torsten Bögershausen <tboegi@web.de>

The "prefix" was precomposed for MacOs in commit 5c327502db,
MacOS: precompose_argv_prefix()

However, this commit forgot to update "startup_info->prefix" after
precomposing.
Re-arrange the code in setup.c:
Move the (possible) precomposition towards the end of
setup_git_directory_gently(), so that precompose_string_if_needed()
can use git_config_get_bool("core.precomposeunicode") correctly.

Keep prefix, startup_info->prefix and GIT_PREFIX_ENVIRONMENT all in sync.

And as a result, the prefix no longer needs to be precomposed in git.c

 This part did never made it to the list - it should have gone only
 to tboegi@web.de
 git send-email decided to cc to the "Helped-by" and "Reported-by" addresses,
 a feature that I was not aware of - and can be turned off with --suppress-cc=all
 In other words, I typically send these emails only to my self first, re-read
 with fresh eyes, and then send them out. End of of blabla.

Changes since V1:
 Add a comment in setup.c, to make more clear that git_config_get_bool()
 is called, and the setup_XXX() must have prepared everything needed.
