strange thumbnails

Issue #95 closed
Bertrand Roessli created an issue

Hello,

if I import new photos into the current directory, ART detects them but some of

the thumbnails are “strange” as shown in the attachment.

If I reopen ART the problem is solved.

I use ART1.3 compiled on Debian.

    I updated to the latest version and modified CMakeCache.txt before compiling but I get the same effect.

    (

    For some reasons I found 2 CMakeCache.txt files one in the directory where I have the script written by Morgan Hardwood that updates and compiles ART and the second one in the build/ subdirectory. So I changed both…

    find -iname "CMakeCache.txt"
    ./code-art/build/CMakeCache.txt
    ./CMakeCache.txt

    )

    I also don’t see anything strange… @Bertrand Roessli do you have to restart ART, or is it enough to refresh the file browser view to fix the thumbnails?

  9. Bertrand Roessli reporter

    Something I did not notice yesterday after recompiling with WITH_MYFILE_MMAP:BOOL=OFF is that if I refresh the browser the bad thumbnails disappear. Only the good onces are left. If I reopen ART only the good ones are visible. The others are missing.

    This was not the case with WITH_MYFILE_MMAP:BOOL=ON.As far as I remember all the files were ok after reopening ART.

    ‌

    I sent you a random orf file sorry. I did not think the problem might be file dependent.

    I put bunch of files in

    Thanks

    Thanks for the samples. However, they all open fine here, no thumbnail corruption.

    Maybe your disk is failing? Did you try opening from a different medium?

  11. Bertrand Roessli reporter

    You are right!

    If I open the files from google drive directly the thumbnails are all fine.

    I repeated the exercise with Rawtherapee with the same effects as in ART. Some of the thumbnails are black. If I refresh the browser than everything is ok.

    I will recompile ART with  WITH_MYFILE_MMAP:BOOL=ON. I can live with the option of refreshing the browser.

    Thanks

    B. Roessli

    May-be the problem comes that I leave ART open and import files from the sd card to the disk and ART/Rawtherapee tries to read a file before it is copied to the end?

    Hello Betrand, that could be quite well possible and explains why the thumbs are okay the second time you open ART/RT. Check that yourself: copy the same photos from your sd card to your disk without running Art, then start Art. Problem solved?

  14. agriggio repo owner

    It might definitely be the case that ART (and RT) tries to read the thumbnail before the file is completely copied. This might then cause the corruption that you are seeing. However, note that using WITH_MYFILE_MMAP=ON can make things worse, not better, as that might lead to ART crashing completely, instead of just not showing the thumbnail
