Re:first capture after meridian flip fails #49525
Source build from git.

Hi everyone
An annoying 'sometimes happens' situation which needs manual intervention.
The first capture after the flip counts down but never reaches zero; it never downloads. This unfortunately means that meridian flips must be attended.

The workaround is simply to abort the capture whereupon the capture is recovered, but it means YOU have to do it:(
This happened at the first flip of the schedule at around 21:18

Any help most gratefully received.

Re:first capture after meridian flip fails #49646
Steve,

I have seen a similar (though probably slightly different) issue. I did look at your log and couldn't quite figure out what was going on, though there are some clues. I added a little logging to the source which might help us figure things out. If you 'git pull' you would get the software with the extra logging. So, please do that, and then, should this ever happen again, please add the new log to this thread.

Thanks,
Hy

Hi Hy
OK, thanks. Can't ATM:

Re:first capture after meridian flip fails #49669
Although that build error should be fixed, you should be able to get around it with just, eg, make -j6 kstars

Re:first capture after meridian flip fails #50041
Side note first, Capture will abort exposure by itself when the post-flip exposure doesn't finish 180 seconds after its expected duration.
I don't see why the flip shouldn't be left unattended, but I can understand these few minutes are wasted (or maybe not, because the frame is actually stored in the APN sdcard).

From the log, the post-flip capture is started and finished at 21:24:38, but the Capture module doesn't react at that point.
The Capture module procedure is then aborted at 21:26:18, though there's nothing to abort really except the procedure itself.

This is my analysis of the log, I marked three FIXMEs that require attention (well the second is quite minor):
- 21:18:41 // Guide aborted guiding, but it seems PHD2 aborts because the mount is slewing, not because it was told to abort (FIXME)[/li]
- 21:21:25 // Capture restarts Guide, though proper log is missing (FIXME)[/li]
- 21:26:18 // Then the INDI driver more or less successfully applies the abort request (FIXME)[/li]

Looking at the code (albeit probably a more recent code than the log source), the function that is *not* called after the flip is "setCaptureComplete".
There are multiple reasons for this:
- no active job - not the case here as it is the source for the exposure duration, unless we loose it during exposure - and it is notable that the OP indicates progress is counting down (capture.cpp:2307)[/li]
- meridian flip still aligning - not the case here, flip stage is set to 0 explicitly at 21:21:33, just before capturing[/li]
- no actual frame data - possible, but probably not the case here?[/li]
- idle or aborted capture - not the case here, capture is active at 21:21:33[/li]
- unexpected sensor source - probably not the case here[/li]
- non-looping preview mode with darks - not the case here[/li]

On the first item, the OP states that the count goes down, but never gets to zero. This count is updated in "setExposureProgress" (capture.cpp:2318), and set to zero explicitly. Except if:
- sensor source is unexpected - probably not the case here[/li]
- fits type isn't normal - not the case, set explicitely at sequencejob.cpp:292[/li]
- meridian flip is still aligning - not the case here, flip stage is set to 0 explicitly at 21:21:33, just before capturing[/li]

So the last remaining point is the lack of data being received by the Capture module.
// Last capture before flip

(...nothing...)

We see that the INDI client doesn't retrieve the data. This is the responsibility of CCD::processBLOB (ekos client, indiccd.cpp:1603), and we're not using websockets because we see the following log (indilib, indiccd.cpp:2845).
[2020-02-14T21:24:38.600 CET DEBG ][           org.kde.kstars.indi] - Canon DSLR EOS 700D : "[DEBUG] BLOB transfer took 0.138315 seconds "

Now the thing to understand is why, following an alignment, the image blob is not retrieved by the Capture module, while the abort procedure of Capture restores functionality.
Situation is not exactly like starting a fresh new sequence, as we are in the middle of a sequence. When we abort, the active job is reset(), and we see prepareJob() being called afterwards.

It means prepareJob() is doing something we should do post-alignment. We do call resumeSequence() at capture.cpp:3266.
We should make sure resumeSequence() is configuring the sensor as properly as prepareJob() is. Or maybe just call prepareJob() instead at that moment.

Re:first capture after meridian flip fails #50042

Capture will abort exposure by itself when the post-flip exposure doesn't finish 180 seconds after its expected duration.


Ah, OK. I didn't know, although I feel sure I waited for more than 3 minutes... Did I?! I had to abort the capture manually so that it would recover and continue.

Re:first capture after meridian flip fails #50057
Just to make it clear, you spotted a real bug that we should fix. That bug is a side-effect of the realignment after flipping. But it appears the system is able to recover from it.

Re:first capture after meridian flip fails #50068
Since we're at it, I just now discovered another problem with the Meridian Flip. It did not occur in the scheduler, I was just using the Capture module and let it run past the time for the flip.
Flip was initiated and completed on the mount (i.e. it was in the [nearly] correct, flipped position, but KStars froze upon initiation of the flip and did not recover.
I had to force quit Kstars and restart it.

Here the log to the event. The log ends with Kstars freezing:

Re:first capture after meridian flip fails #50166

If you 'git pull' you would get the software with the extra logging. So, please do that, and then, should this ever happen again, please add the new log to this thread.


Hi
Not after meridian flip but fails to download. Maybe the flip was misleading. Capture counts down, reached 0.1s and waits until timed out.

Re:first capture after meridian flip fails #50189
I'll have a look at the log, but the issue is bound to happen after the alignment phase, if the sequence is resuming and not restarting. Meridian flip just happens to trigger that sequence every time.

Re:first capture after meridian flip fails #50191

I'll have a look at the log

Hi
No problem. I posted mainly for @hy who had put in some extra debugging.
Now we know it times out and recovers, NP.

Re:first capture after meridian flip fails #50205
Thanks for doing that. I did look at you log, log_21-24-08.txt, but nothing was obvious. Here's what I saw:

BTW, the log is full of lots of unhelpful messages (for this--no problem and not your fault) so below I've grepped out a lot of lines as follows in the below examples
grep -v -i eqmod ~/Desktop/log_21-24-08.txt | grep -v -i phd2 > ~/zz

You can see that the previous exposure, starts

***** note the processBLOB() at the end. Without that, capture/focus/align/fitsviewer will not receive the image.


In the next, failed exposure:

Going to the end of that exposure, it looks like indi receives the image, but the processBLOB() log is never printed.

The debug log for processBlob() in kstars/indi/indiccd.cpp is not right at the start of the method, but pretty close, after it filters out ccd type and blob type. I don't know what's going on there either, but I think that either indi is not sending the blob to ekos, or indi is mispackaging it (eg assigning it the wrong blob type or ccd type). The debug statement on line 1566 of indiccd.cpp is not reached or printed, indicating that processBLOB isn't running, but yet it's clear from the log that the indi driver downloaded the image.

I too am seeing stalled exposures from time-to-time too. Not frequently, but I have seen it happen. I really have no experience with indi or the indi/kstars communictions. Does someone out there know why indi might not transfer the image to indiccd.cpp?

I may put several more logging statements in the source on my raspberry pi in hopes of catching something. I would like to put a couple more debugging logs in the code. Hopefully the next time it happens to me, I can get a few more clues.
