Lensfun : last commits of master branch break compatibility, waiting for alpha version #4601

Closed gaaned92 closed 6 years ago

gaaned92 commented 6 years ago

As noticed here https://discuss.pixls.us/t/rawtherapee-dev-5-4-374-g83e686a71-winvista-64-doesnt-start/8014, Rawtherapee suddenly stops during initialisation when starting directly by double clicking or in a mingw shell for each start, it doesn't stop at the same place.

Beep6581 commented 6 years ago

@gaaned92 is this Windows 10?

heckflosse commented 6 years ago

5.4-383-g168309f45 works fine on win7

gaaned92 commented 6 years ago

@Beep6581 yes on W10

@heckflosse Is it a build from you? or from me ? As I rebuilt lensfun master branch, there is perhaps a problem with it?

Floessie commented 6 years ago

@gaaned92

As I rebuilt lensfun master branch, there is perhaps a problem with it?

Does it always hang during lensfun DB loading?

heckflosse commented 6 years ago

@gaaned92 my own build

Benitoite commented 6 years ago

@gaaned92 Have you tried the Windows 7 Compatibility Mode?

gaaned92 commented 6 years ago

@heckflosse do you build lensfun yourself? or do you use the old msys2 lensfun lib?

@Floessie It reads the bundled PP3 and DCP. No lensfun message

So seems I have to revert lensfun master but to what commit?

Floessie commented 6 years ago

@gaaned92

So seems I have to revert lensfun master but to what commit?

I wouldn't conclude it's lensfun's fault from what I've read so far in this issue. There's still Win7 vs. Win10 and your build vs. Ingo's build.

I was just asking whether it always hangs when reading the lensfun DB, because in #4580 we found out that the lensfun API isn't thread-safe.

heckflosse commented 6 years ago

@gaaned92 I use the old msys2 lensfun lib

gaaned92 commented 6 years ago

@Floessie 5.4-342-g6adc09071 runs ok with old lensfun build but It stops with new lensfun build.

Then following @Benitoite advice, I opened rawtherapee.exe property window, then compatibility then solve compatibility problem. W10 set up Windows 8 compatibility mode then program slowly starts.

Nevertheless trying to revert lensfun.

I don't know if it help, but I've just compiled nightly-187-g168309f45 on my w10 and it has no problems with start.

@Kildor there is an error in your repo, see this to fix it: https://github.com/Beep6581/RawTherapee/issues/4509#issuecomment-382731056 or delete your repo and clone again.

gaaned92 commented 6 years ago

Definitly a problem with Lensfun master branch. Using master commit 781e56ca96, RT aborts unless you change compatibility to Windows 8. Using master commit 2a186cb1e, RT starts ok.

gaaned92 commented 6 years ago

@heckflosse @agriggio @Benitoite Do I close this thread as it seems we have to wait for the new version?

Benitoite commented 6 years ago

🤙 @gaaned92 you might like to edit the title to reflect the issue with lensfun 🤔

Beep6581 commented 6 years ago

RT should support the latest-stable lensfun release, regardless how old, because most distros won't ship an alpha version of lensfun.

gaaned92 commented 6 years ago

Yes , sure for RT stable version . Nevertheless, there could be some branch supporting new lensfun development.
