- * return value, if not NULL, is a pointer into either a static buffer
- * or the input ref.
- *
- * If the reference cannot be resolved to an object, the behavior
- * depends on the RESOLVE_REF_READING flag:
- *
- * - If RESOLVE_REF_READING is set, return NULL.
+ * Convert a binary sha1 to its hex equivalent. The `_r` variant is reentrant,
+ * and writes the NUL-terminated output to the buffer `out`, which must be at
+ * least `GIT_SHA1_HEXSZ + 1` bytes, and returns a pointer to out for
+ * convenience.
*
- * - If RESOLVE_REF_READING is not set, clear sha1 and return the name of
- * the last reference name in the chain, which will either be a non-symbolic
- * reference or an undefined reference. If this is a prelude to
- * "writing" to the ref, the return value is the name of the ref
- * that will actually be created or changed.
+ * The non-`_r` variant returns a static buffer, but uses a ring of 4
+ * buffers, making it safe to make multiple calls for a single statement, like:
*
- * If the RESOLVE_REF_NO_RECURSE flag is passed, only resolves one
- * level of symbolic reference. The value stored in sha1 for a symbolic
- * reference will always be null_sha1 in this case, and the return
- * value is the reference that the symref refers to directly.
- *
- * If flags is non-NULL, set the value that it points to the
- * combination of REF_ISPACKED (if the reference was found among the
- * packed references), REF_ISSYMREF (if the initial reference was a
- * symbolic reference), REF_BAD_NAME (if the reference name is ill
- * formed --- see RESOLVE_REF_ALLOW_BAD_NAME below), and REF_ISBROKEN
- * (if the ref is malformed or has a bad name). See refs.h for more detail
- * on each flag.
- *
- * If ref is not a properly-formatted, normalized reference, return
- * NULL. If more than MAXDEPTH recursive symbolic lookups are needed,
- * give up and return NULL.
- *
- * RESOLVE_REF_ALLOW_BAD_NAME allows resolving refs even when their
- * name is invalid according to git-check-ref-format(1). If the name
- * is bad then the value stored in sha1 will be null_sha1 and the two
- * flags REF_ISBROKEN and REF_BAD_NAME will be set.
- *
- * Even with RESOLVE_REF_ALLOW_BAD_NAME, names that escape the refs/
- * directory and do not consist of all caps and underscores cannot be
- * resolved. The function returns NULL for such ref names.
- * Caps and underscores refers to the special refs, such as HEAD,
- * FETCH_HEAD and friends, that all live outside of the refs/ directory.
