Subject: [PATCH] convert: constify some variables in ident_to_worktree()
Date: Mon,  9 Mar 2026 21:03:40 -0700	[thread overview]
Message-ID: <d3447c19d83c37bf2db84ae0bf75801ef7a36cea.1773115420.git.collin.funk1@gmail.com> (raw)

When building with glibc-2.43 there is the following warnings:

    convert.c: In function ‘ident_to_worktree’:
    convert.c:1189:24: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
     1189 |                 dollar = memchr(src, '$', len);
          |                        ^
    convert.c:1212:32: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
     1212 |                         dollar = memchr(src + 3, '$', len - 3);
          |                                ^
    convert.c:1223:29: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
     1223 |                         spc = memchr(src + 4, ' ', dollar - src - 4);
          |                             ^

The "dollar" and "space" pointers are used to iterate over the const
string "src". Since they are never written to we can make them const
too.
