Thanks for reporting this @seattleite7, that sounds like the kind of thing we'll want to fix sooner rather than later. 😉

chrisjlocke · 2020-07-03T05:25:15Z

Does this do this every time? Even after restarting DB4S?
Can you confirm I've done your steps?
https://screencast-o-matic.com/watch/cYiehZ5tHA

I tried a bunch of other actions (just in case) but couldn't trigger the crash.
Just for the avoidance of doubt, could you try the 32-bit version of DB4S as well?

seattleite7 · 2020-07-03T06:38:10Z

@chrisjlocke Yes you followed the steps correctly. I don't get the crash on 32-bit. But I get it every time on 64-bit even after restarting DB4S.

chrisjlocke · 2020-07-03T07:49:41Z

Thanks for confirming.
When you say 'crash' is this a 'DB Browser for SQLite has stopped responding' type thing? Any chance of a screenshot? (it can be pasted here). If there is a 'more details' link at the bottom, if that can be clicked to show the first couple of lines....

seattleite7 · 2020-07-03T09:00:29Z

@chrisjlocke "crash" means "terminates immediately", no error message.

chrisjlocke · 2020-07-03T09:42:33Z

Excellent, thanks.

mgrojo · 2020-07-04T12:50:37Z

Weird. I cannot reproduce it either under Linux. So the problem is only present in the 64 bit version but not for all users. By the way, with the current version I cannot longer run the ZIP version of Windows under Wine. It crashes immediately, both in the 32 bits as in the 64 bit version. It might be a problem in Wine, but it doesn't happen with v3.11.2.

chrisjlocke · 2020-07-04T13:03:11Z

Do the nightlies crash too?

mgrojo · 2020-07-04T13:57:35Z

The nightlies too. It faults with these details (in case it gives some hint to anyone, not my case):

@mgrojo Interesting wine crash there. How easy would it be for you to figure out when it started crashing?

eg by trying various of the win nightly builds

We can probably narrow down if it's something we did, or if it's more likely something to do with Qt 5.12.8.

MKleusberg · 2020-07-08T13:53:14Z

@seattleite7 I can't reproduce the crash either. Can you maybe follow the instructions here and copy the debug information you get after the crash in here?

seattleite7 · 2020-07-09T03:45:27Z

@MKleusberg

I had QT 5.9.2 installed. When I uninstalled it, it did not crash anymore. Below is the debug information for the crash (see bold)

I had QT 5.9.2 installed. When I uninstalled it, it did not crash anymore.

Ahhh. So the wrong Qt libraries were being loaded. In hind sight, that makes sense for the crash to happen.

But (in theory), it's weird just having Qt 5.9.2 installed was somehow getting that to be loaded instead of the Qt 5.12.8 libraries our installer includes. Maybe some kind of system setting or environment variable thing?

MKleusberg · 2020-07-09T08:04:24Z

Interesting. You can see how the different Qt versions are mixed here:

...

I wonder why it's just loading Qt5Svg.dll from that different path. Maybe we don't include it in our installer? That could be easily fixed then by just adding it to our installer.

chrisjlocke · 2020-07-09T08:19:07Z

Maybe we don't include it in our installer?

Should we be? I can't find that file in any of our downloads, so its not an 'essential' file. The file description isn't that helpful.

Assume its just an SVG library, which I also assume we don't use.

MKleusberg · 2020-07-09T08:23:31Z

Yeah, I was thinking the same. We probably don't use it. On the other hand DB4S does try to load it for whatever reason.

justinclift · 2020-07-09T08:58:38Z

Maybe we don't include it in our installer?

The line right above that is the Qt SVG imageformat dll:

ModLoad: 00007ffb06ad0000 00007ffb06adc000 C:\Program Files\DB Browser for SQLite\imageformats\qsvg.dll

That's what our CMakeLists.txt has too. No idea where the Qt5Svg.dll filename is coming from.

Maybe there's some kind of override in an environment variable or similar?

MKleusberg · 2020-07-09T09:13:12Z

Looking at the Qt source code, it seems like their image formats project doesn't have a plugin for SVG. Instead that plugin is part of the QtSVG project. So maybe that means that the SVG plugin depends on the entire SVG module and cannot be used as a standalone plugin like the other image formats. Also it looks like a <?xml anywhere close to the beginning of the data makes it interesting for the SVG plugin and finally the SVG image format plugin makes heavy use of the QSvgRenderer class which is part of the QtSVG module.

Unfortunately I couldn't find any documentation on this but I believe qsvg.dll loads Qt5Svg.dll and, if it cannot find a copy if that in the current directory, will start looking in other places.

justinclift · 2020-07-09T09:31:56Z

Interesting. There's no Qt5Svg.dll anywhere under the installed Qt 5.12.8 plugins folder. But it does exist in the bin directory.

We should be able to add that to our installer packages, by adding it to the right places. Probably these:

sqlitebrowser/CMakeLists.txt

Line 295 in cf9fc5c

# Windows image format plugin files
sqlitebrowser/installer/windows/product.wxs

Line 63 in cf9fc5c

<Directory Id="imageformats" Name="imageformats">
sqlitebrowser/installer/windows/product.wxs

Line 162 in cf9fc5c

justinclift · 2020-07-09T10:45:42Z

I'm too brain-dead tired atm to make that change.

If someone else wants to get it done, it'll be automatically picked up by the build system tomorrow onwards. 😄

mgrojo · 2020-07-30T11:29:54Z

@mgrojo Interesting wine crash there. How easy would it be for you to figure out when it started crashing?

eg by trying various of the win nightly builds

We can probably narrow down if it's something we did, or if it's more likely something to do with Qt 5.12.8.

I had some time to test that. The last version to work was DB.Browser.for.SQLite-2019-11-11-win64.zip and the first which didn't work was DB.Browser.for.SQLite-2019-11-19-win64.zip. Looking at the history, the only one that I think could have had this effect would be 574303a which updated Qt from v5.12.5 to v5.12.6.

justinclift · 2020-07-30T23:25:18Z

This completely slipped my mind.

I'll have a go at updating our Windows packaging so it includes the Qt5Svg.dll file, and lets see what happens.

On that note, if it works then we'll probably need to do the same for macOS, Linux (AppImage) as well.

See issue #2321

justinclift · 2020-07-31T00:13:41Z

@mgrojo Looks like Wine doesn't like that newer revision of Qt. 😦

There's a newer Qt revision out now (v5.12.9) too, compared to what we're using at the moment (v5.12.8).

I'd been planning to update the build VM's with that anyway. We might as well see if it fixes things.

If not, we could revert back to the older Qt 5.12.5. The updating to 5.12.8 was just because (in theory) newer Qt 5.12.x releases should be less buggy. That theory doesn't always seem to hold true though. 🤷

justinclift · 2020-07-31T00:17:09Z

@seattleite7 Any interest in testing the new 64-bit Windows package here?

https://nightlies.sqlitebrowser.org/latest/

That now includes the Qt5Svg.dll file, which seems like it should fix the crash. In theory. 😄

seattleite7 · 2020-08-02T08:20:03Z

@justinclift
No crashes so far :)

justinclift · 2020-08-02T09:31:57Z

Cool. 😄

Would you be ok to install Qt 5.9.2 again, and see if the crash comes back?

Just wanting to make super sure adding the Qt5Svg.dll file is a complete fix. 😄

seattleite7 · 2020-08-03T07:45:05Z

@justinclift No crashes with Qt 5.9.2 installed.

justinclift · 2020-08-03T09:57:58Z

Awesome! Sounds like including Qt5Svg.dll is good enough then. *whew*

Thanks for taking the extra time to double check that @seattleite7. 😄
