ajax/stream.php only included `auth` in its reply when it differed from
the hash the request carried. That hash comes from auth_relay, while the
browser stamps stream <img> URLs from a separate auth_hash global, so once
the two drifted the condition held permanently and the stale copy was
never corrected.
Observed on a montage page: a reload minted a new connkey and baked the
drifted hash into the src, after which every native <img> reconnect got a
403 from zms for nearly five hours.
Send it unconditionally; it is 32 bytes on a response that already carries
auth_relay.
Three points raised on #5038 after it was merged.
ajaxError() documents the reason field as included "only when set", but
tested it for truthiness, which would also drop '' and '0'. None of the
four STREAM_ERR_ constants are falsy so nothing changed behaviour, but
the check now matches the documented contract. The client already treats
an empty reason as fatal, so a caller that does pass one still gets the
old handling.
The case 0 branch called ajaxError() twice in sequence and relied on the
first one exiting to keep the second from running on a timeout. Made the
two paths mutually exclusive so it no longer depends on that.
The test's "every ajaxError call is classified" assertion compared the
number of call sites to the number of STREAM_ERR_ occurrences anywhere in
the file. The four define()s are part of that count, so up to four calls
could lose their classification and the test would still pass - verified
by dropping the argument from one call, which the old assertion accepted.
It now matches each call to the end of its statement and requires every
one to carry a constant.
getStreamCmdResponse() responded to every ajax/stream.php failure the same way:
mint a fresh connkey and reload the img src. ajaxError() returns HTTP 200 with
result=Error, so these arrive in jQuery's done() rather than fail(), and all
twelve error paths in stream.php took that branch.
Only one of them means zms is gone. For the rest the process is still running
and streaming, and replacing the connkey makes it unaddressable: CMD_STOP,
CMD_QUIT and mode=single all then go to the new key, so nothing can reach the
old process and only SIGPIPE can stop it, which we know is unreliable. That is
why the reports of lingering zms after switching monitors were unaffected by
changes to what the stop path sends.
The timeout path made this routine rather than rare. On select() expiry
ajaxError is commented out, so the script carries on to socket_recvfrom() on a
now non-blocking socket. That returns false, and false == 0 under switch's loose
comparison, so a merely slow zms was reported as 'No data to read from socket'
and torn down.
stream.php now classifies each failure as no_socket, timeout, transient or
invalid, and sends it as 'reason'. The client restarts the stream only for
no_socket. A missing reason is still treated as fatal, so a php that predates
this keeps the old behaviour.
Before replacing the connkey the client now sends CMD_QUIT to the old one, so
the process we are about to lose track of is asked to exit. That is deliberately
not routed through streamCommand(): it must name its target explicitly, since
this.connKey is about to change, and its response must not feed back into
getStreamCmdResponse(), or a QUIT that also failed would re-enter the error path
and loop.
ajaxError() takes the classification as a third argument, named $reason because
$code is already the HTTP status, and only includes it when set, so the other
131 callers are unaffected.
Tests: tests/js covers the fatal/non-fatal decision including the no-reason
fallback, tests/php pins the classification mapping and the switch(false)
semantics the timeout branch depends on. Both verified to fail when the
behaviour is reverted.

When CMD_STOP is sent via AJAX using ZMS MJPEG streaming, the response
was incorrectly returning paused=true instead of indicating a stopped
state (paused=false).
Changes:
- Add `stopped` boolean to StreamBase (zm_stream.h)
- MonitorStream: CMD_STOP now sets stopped=true, paused=false instead
of paused=true; run loop skips frame sending when stopped
- EventStream: CMD_STOP sets stopped=true (was already setting
paused=false); run loop skips frame sending when stopped
- All other play/pause commands reset stopped=false
- Both streams include stopped field in the status response struct
- stream.php unpacks the new stopped field from MSG_DATA_WATCH and
MSG_DATA_EVENT responses
- MonitorStream.js handles stopped status in UI (shows 'Stopped' mode)
- EventStream.js tracks stopped state from server response
Fixes issue: CMD_STOP response paused=true should be paused=false

Add a boolean analysis_image field to the CMD_QUERY status response that
reports whether zms is actually sending analysis images (with motion zone
overlays) or regular capture images. This lets MonitorStream.js detect
when the stream state is out of sync with what the client requested and
re-send the CMD_ANALYZE_ON/OFF command to correct it.
The field is true only when frame_type is FRAME_ANALYSIS, shared memory
is valid, and the monitor has analysis enabled — matching the same
condition used to select the image in the streaming loop.

Keep track of last_id which is the last frame id that we have info for. Use it instead of Frame Count to prevent
accessing non-existent frame records
close ffmpeg_input on event change
include duration in status messages because it may change when playing an in-progress event.
when we hit the end of our frame data if it is an in-progress event, reload the event data instead of moving to the next event.
Include X-Timestamp in http headers to match live stream behaviour
Only send time to next event when mode=ALL
