+
+     Summary: prior to version 3.50.0 computeDigest() always computes
+     a value of [0,0] due to overflows, so it does not do anything
+     useful.  Fixing it invalidates old persistent files, so we
+     instead only fix it for files created or updated since the bug
+     was discovered and fixed.
+
+     This flag determines whether we use the broken legacy
+     computeDigest() or the v2 variant. We only use this flag for
+     newly-created/overwritten files. Pre-existing files have the
+     broken digest stored in them so need to continue to use that.
+
+     What this means, in terms of db file compatibility between
+     versions:
+
+     - DBs created with versions older than this fix (<3.50.0)
+     can be read by post-fix versions. Such DBs which are written
+     to in-place (not replaced) by newer versions can still be read
+     by older versions, as the affected digest is only modified
+     when the SAH slot is assigned to a given filename.
+
+     - DBs created with post-fix versions will, when read by a pre-fix
+     version, be seen as having a "bad digest" and will be
+     unceremoniously replaced by that pre-fix version. When swapping
+     back to a post-fix version, that version will see that the file
+     entry is missing the FLAG_COMPUTE_DIGEST_V2 bit so will treat it
+     as a legacy file.
+
+     This flag is stored in the same memory as the various
+     SQLITE_OPEN_... flags and we must be careful here to not use a
+     flag bit which is otherwise relevant for the VFS.
+     SQLITE_OPEN_MEMORY is handled by sqlite3_open_v2() and friends,
+     not the VFS, so we'll repurpose that one.  If we take a
+     currently-unused bit and it ends up, at some later point, being
+     used, we would have to invalidate existing VFS files in order to
+     move to another bit.  Similarly, if the SQLITE_OPEN_MEMORY bit
+     were ever reassigned (which it won't be!), we'd invalidate all
+     VFS-side files.

+
+        This is a bugfix test for the OPFS SAHPool VFS. It requires
+        setting up a database created using v3.49.0 or older, then
+        running it again with a newer version. In that case, the newer
+        version should be able to read the older version's db files
+        just fine. Revering back to the old version should also still
+        work - it should be able to read databases modified by the
+        newer version. However, a database _created_ by a version with
+        this fix will _not_ be legible by a version which predates
+        this fix, in which case the older version will see that VFS
+        file slot as corrupt and will clear it for re-use.
+
+        This is unfortunately rather cumbersome to test properly,
+        and essentially impossible to automate.
