Zoneminder Segfault after MariaDB-10.1.34

Hu · Moderator Joined: 06 Mar 2007 Posts: 21602

While I would need to see the specific bug explanation to be sure, my first inclination is to say that it is not a problem with old code bases failing to keep up. It is a problem of old code bases that were always wrong, and are no longer permitted to be silently wrong. Old code that was right the first time does not mysteriously break on glibc upgrades. If it were, we would have far bigger problems with far more central packages.

That's a good way to look at it.

I just made my first custom ebuild tonight to install zoneminder-1.32.0 after getting the same glibc segfault issue. It works!

I removed the patches from the zoneminder-1.30.4 ebuild and found a problem with /var/tmp/portage/www-misc/zoneminder-1.32.0/image///etc/conf.d/README
The README has mismatched single quotes that break the build. Deleting it while the build is running is a hacky way to get around the problem, but it works.

Had to make these sql changes before zmupdate.pl would run cleanly:

Inspired by jiminim and frustrated by a lack of zoneminder, I figured I'd give it a go as well.

I copied the old 1.30.4 ebuild, migrated the diskspace patch and dropped the others.

Yeah, I ended up applying all the changes from b0c5555.
As well as a few other tweaks to Monitor.php and Event.php which were missed in that commit.

So everything looks perfect and is behaving quite well with no errors in the console.

I do however seem to have an issue where zmaudit.pl keeps ending up with a stale pid file.
And I still haven't fixed the reverse proxy :roll:

Still, progress!
It otherwise seems really stable which is great given the amount of sins committed to get it going.

Could someone who got it working post the ebuild and files folder additions so we don't have to do everything by hand following the posts as a guide?

Sure thing.
Everything is working fine as near as I can tell... it's doing the job I need it to do at least.

There have been two minor releases since this threads started, so this ebuild is for 1.32.2.
I've modified it to create the cache directory and it does not require any extra patching.
So this should just work

The problem I mentioned earlier in the thread with zmaudit.pl was caused by a missing perl dependency (as always).
Just run the script manually and it'll highlight anything missing for your system.
I also had a missing dependancy for zmtrigger.pl.
I needed to install

Thanks!

I created my own ebuild over the weekend and got 32.1 working. I had a few database issues, but this thread helped me figure it out.

I'll try updating with your ebuild as soon as I get some time.

Well spotted... I was consistent too :lol:

Gave n3r0's ebuild a whirl at the weekend and it compiled and installed without a hitch.

One of the new features of v1.32.2 is the ability to encode x264 videos of events as they happen, but this needs media-libs/libmp4v2 installed at compile time. Zoneminder will still compile and run without it, but setting the "video writer" to "x264 encode" will cause event recording to fail silently.

But I don't know...

if ffmpeg is needed as well for x264 encoding or not.
if the ebuild should always pull in libmp4v2, or if the USE flag "encode" or "x264" should let the user decide.

Unfortunately I've had to roll back to v1.30.2 since I encountered a regression that stops the playback controls working. Not a fault with the ebuild at all, as someone running Fedora 28 has reported the same issue.

Interesting, I had a look and I have the same issue with the controls returning 500 errors on the old jpeg stored events.

My cameras are setup such that I have a primary channel which is high res h264 and a sub channel which is lower res mjpg.
Modect is setup on the sub channels and used to trigger the primaries (shared across cameras).

Events on the primary channels are setup as h264 passthrough and work as expected, including the feed controls.
Events on the sub channels display the events, but indeed the feed controls return 500 errors.

I've been meaning to try the new ffmpeg support in zoneminder... so now's as good a time as any.
I modified the ebuild (I'll edit my earlier post again for anyone finding this later) to include libmp4v2 under the encode flag.
This was automatically pulled into my setup when I re-emerged the package.

Changed the storage of the two sub channels to X264 Encode and... everything just works.

1.32.3 should bring a fix for all, but for myself, the switch to using the x264 encoder is acceptable.

I also fell into the DB trap, and couldn't back out of it because the .31-r1 version of mariadb has fallen out of the tree.

Grabbed n3r0's 1.32.2 ebuild, but that doesn't compile for me. It claims

Had another bash after finding out what caused my playback controls to stop working. It turns out it uses semaphores which are not compiled into PHP by default, unless the sysvipc USE flag is set. Re-emerging PHP with this USE flag solves the problem for me.

A patch was merged to make it work properly without sysvipc so only the ebuild for this version should need PHP with that USE flag set, assuming the patch makes it into the next release.

For versions where dev-lang/php[sysvipc] is mandatory for proper ZoneMinder operation, the ZoneMinder ebuild should use a USE dependency to declare this. That will cause Portage to require the user to fix this flag at install time, before the user has a chance to have ZoneMinder fail and require debugging.

Epilogue: I'm now running ZM 1.32.2 with mysql-connector-c 6.1.11-r1 and mariadb 10.3.8. It all seems to be working fine (though the CPU load appears to be higher, I may have to give that VM some more cores)

I used the ebuild posted above, with the mod suggested by Hu to require dev-lang/php[ffmpeg]. As above, I had a few issues getting the DB migrated/upgraded, but nothing too egregious to get through.

I'm masking higher versions of these components, so I'll have a chance to proceed more cautiously when they show up.

I just realized that even though it looks like recordings are being made, they don't play back... Has anyone see this?

I'm going to start digging in now, but I was hoping for a pointer from someone who had a similar problem.

I'm getting this warning:

Cannot write to content dirs('/var/lib/zoneminder/events','/var/lib/zoneminder/images'). Check that these exist and are owned by the web account user

/etc/zm.conf is in the apache group.

zm.conf points to a completely different directory for storing the events:

For those who are trying to figure this out. There is a file called *.conf (it can be anything, mine is called, 'zmcustom.conf') which contains overrides for zoneminder. The paths were set in that file and I updated them to the proper path and fixed the issue.

Chipping in on this thread, i am working on installing ZoneMinder 1.32.3 now.

I have updated the ebuild, since one perl dependency was missing:
