Review findings on the coverage branch.
The download size cap I added checked len(response.content), which has
already buffered the whole body -- it stopped the bytes reaching disk but
not memory, which was the point. A server that omits Content-Length and
never stops sending would still exhaust the process. Stream it instead,
counting as it arrives, into a sibling .part file that is replaced over
the target only once it decodes. A transfer that dies midway now leaves
nothing behind rather than a truncated logo for load_logo() to cache.
The follower's control-message handler caught three exception types, but
two reachable UDP payloads raise others: a bare JSON scalar makes
msg.get() raise AttributeError, and an "sx" carrying a non-numeric x
raises ValueError or TypeError from float(). Those escaped to the outer
handler, skipping the legacy-PNG fallback and -- since this branch added
a backoff there -- charging one malformed packet a 0.1s stall on the
receive path. The legacy-PNG path also decoded without the dimension cap
its TCP counterpart applies, so a crafted 65KB frame could force a large
allocation on the render thread; both paths now share one constant.
Three repo_url handlers called .strip() on client input without checking
it was a string, so {"repo_url": 12345} answered 500. The credentials
upload parsed the same file twice, the second time inside a bare except
that a preceding parse had already made unreachable. And both raw-config
handlers kept a json.JSONDecodeError arm that get_json(silent=True) had
turned into dead code, collapsing "sent something unparseable" into "sent
nothing" -- they now say which.
Two of the new tests were not testing what they claimed. The pruning
round-trip wrote ten backups inside one second, so all ten landed on the
same int(time.time()) filename and overwrote each other; it never reached
the limit it asserted. And the sync clock helper patched attributes on the
stdlib time module, freezing time process-wide for every daemon thread
earlier tests had left running.
Full suite: 3352 passed, coverage 54%.
