Subject: builtin/mktree: remove USE_THE_REPOSITORY_VARIABLE
X-Git-Tag: v2.54.0-rc0~46^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=78827970ecf1cb853fc2c9059c180f91fa154c97;p=thirdparty%2Fgit.git

builtin/mktree: remove USE_THE_REPOSITORY_VARIABLE

The 'cmd_mktree()' function already receives a 'struct repository *repo'
pointer, but it was previously marked as UNUSED.

Pass the 'repo' pointer down to 'mktree_line()' and 'write_tree()'.
Consequently, remove the 'USE_THE_REPOSITORY_VARIABLE' macro, replace
usages of 'the_repository', and swap 'parse_oid_hex()' with its context-aware
version 'parse_oid_hex_algop()'.

This refactoring is safe because 'cmd_mktree()' is registered with the
'RUN_SETUP' flag in 'git.c', which guarantees that the command is
executed within a initialized repository, ensuring that the passed 'repo'
pointer is never 'NULL'.
