*
* tag: Any tags associated with this message by the user.
*
+ * direntry: A colon-separated pair of values (INTEGER:STRING),
+ * where INTEGER is the document ID of a directory
+ * document, and STRING is the name of a file within
+ * that directory for this mail message.
+ *
* A mail document also has two values:
*
* TIMESTAMP: The time_t value corresponding to the message's
* user in searching. But the database doesn't really care itself
* about any of these.
*
- * Finally, the data portion of a mail document contains the path name
- * of the mail message (relative to the database path).
+ * The data portion of a mail document is empty.
*
* Directory document
* ------------------
* The directory document contains the following terms:
*
* directory: The directory path (relative to the database path)
+ * Or the SHA1 sum of the directory path (if the
+ * path itself is too long to fit in a Xapian
+ * term).
+ *
* parent: The document ID of the parent directory document.
* Top-level directories will have a parent value of 0.
*
* and has a single value:
*
* TIMESTAMP: The mtime of the directory (at last scan)
+ *
+ * The data portion of a directory document contains the path of the
+ * directory (relative to the datbase path).

/* With these prefix values we follow the conventions published here:
{ "reference", "XREFERENCE" },
{ "replyto", "XREPLYTO" },
{ "directory", "XDIRECTORY" },
+ { "direntry", "XDIRENTRY" },
{ "parent", "XPARENT" },
};
return path;

-/* Given a 'path' (relative to the database path) return the document
- * ID of the directory document corresponding to the parent directory
- * of 'path' in 'parent_id'.
+/* Given a path, split it into two parts: the directory part is all
+ * components except for the last, and the basename is that last
+ * component. Getting the return-value for either part is optional
+ * (the caller can pass NULL).
*
* The original 'path' can represent either a regular file or a
- * directory, (in either case, the document ID of the parent will be
- * returned). Trailing slashes on 'path' will be ignored, and any
+ * directory---the splitting will be carried out in the same way in
+ * either case. Trailing slashes on 'path' will be ignored, and any
* cases of multiple '/' characters appearing in series will be
* treated as a single '/'.
*
- * If no directory document exists in the database for the parent, (or
- * for any of its parents up to the top-level database path), then
- * directory documents will be created for these (each with an mtime
- * of 0).
- *
- * Return value:
- *
- * NOTMUCH_STATUS_SUCCESS: Valid value available in parent_id.
+ * Allocation (if any) will have 'ctx' as the talloc owner. But
+ * pointers will be returned within the original path string whenever
+ * possible.
*
- * NOTMUCH_STATUS_XAPIAN_EXCEPTION: A Xapian exception
- * occurred and parent_id will be set to (unsigned) -1.
+ * Note: If 'path' is non-empty and contains no non-trailing slash,
+ * (that is, consists of a filename with no parent directory), then
+ * the directory returned will be an empty string. However, if 'path'
+ * is an empty string, then both directory and basename will be
+ * returned as NULL.
