Subject: [PATCH v7] git: edit variable types to match what is assigned to them
Date: Fri, 23 Dec 2022 19:40:25 +0000	[thread overview]
Message-ID: <pull.1399.v7.git.git.1671824426074.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1399.v6.git.git.1671824140973.gitgitgadget@gmail.com>

From: Seija Kijin <doremylover123@gmail.com>

There are many places where "int len = strlen(foo);" is written,
just for len to be passed as a parameter of size_t.

This causes truncation and then expansion
back from int to size_t. This is poor logic.

    git: edit variable types to match what is assigned to them
    
    There are many places where "int len = strlen(foo);" is written, just
    for len to be passed as a parameter of size_t. This causes truncation
    and then expansion back from int to size_t. Not to mention this is poor
    logic and needless truncations can add extra unneeded instructions.
