[PATCH v2 2/7] wt-status: print to s->fp, not stdout

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We pass around a `FILE *` in the `struct wt_status` and almost always
print to it. But in a few places, we write to `stdout` instead, either
explicitly through `fprintf(stdout, ...)` or implicitly with
`printf(...)` (and a few `putchar(...)`).

Always be explicit about writing to `s->fp`. To the best of my
understanding, this never mattered in practice because these spots are
involved in various forms of `git status` which always end up at
standard output anyway. When we do write to another file, it's because
we're creating a commit message template, and these code paths aren't
involved.

But let's be consistent to help future readers and avoid future bugs.
