Thread:Project:Support desk/image resize thumbnails on synology diskstation/reply (3)

thanks guys, i checked by turning on those options in LocalSettings.php

$wgShowExceptionDetails = true; $wgDebugToolbar = true; $wgShowDebug = true; $gwDevelopmentWarnings = true; $wgShowSQLErrors = true; $wgDebugDumpSql = true; $wgShowDBErrorBacktrace = true;

alright, so I loaded an article with a thumbnail on it and on the thumbnail it says: ehler beim Erstellen des Vorschaubildes: Warning: passthru: PHP exec disable. in /volume1/web/mediawiki/includes/GlobalFunctions.php on line 2854

which wonders me, so I checked if there is a) safe_mode=off and b) there is no disable_function set

I also tested these PHP scripts: 

and



I put them in the mediawiki main directory where the index.php is and ran them. They output "exec is enabled" and "safe mode is off".

So how could exec still be disabled?

I also set up a log file with $wgDebugFile and when i search convert it says this line: BitmapHandler::transformImageMagick: running ImageMagick: '/usr/bin/convert' -quality 95 -background white '/volume1/web/mediawiki/uploads/d/de/Firemans_carry.png'  -thumbnail '100x63!' -set comment 'File source: http://mydomain/mediawiki/index.php/Datei:Firemans_carry.png' -depth 8   -rotate -0   '/volume1/web/mediawiki/uploads/temp/transform_7b7f803965ea-1.png' 2>&1

when I copy the line and get it running on the shell beginnine with /usr/bin/convert, it works. in the temp directory there is a nice small .png file which I can open

when i search Next, I am getting this line wfShellExec: /bin/bash '/volume1/web/mediawiki/includes/limit.sh' 'OMP_NUM_THREADS='\1'\ '\/usr/bin/convert'\ -quality 95 -background white '\/volume1/web/mediawiki/uploads/d/de/Firemans_carry.png'\  -thumbnail '\100x63!'\ -set comment '\File source: mydomain/mediawiki/index.php/Datei:Firemans_carry.png'\ -depth 8   -rotate -0   '\/volume1/web/mediawiki/uploads/temp/transform_7b7f803965ea-1.png'\ 2>&1' 'MW_CPU_LIMIT=180; MW_CGROUP='\'\; MW_MEM_LIMIT=409600; MW_FILE_SIZE_LIMIT=102400; MW_WALL_CLOCK_LIMIT=180'

ok, first thing I tried was to try this line on the shell as well and see - it says /bin/bash - file does not exist. Since Synology Diskstation is using Apache IPKG as Package Management because it needs special installation packages made for it's marvell ARM processor, it is installing new packages in /opt/bin. So I made a link from /opt/bin/bash to /bin/bash and now this line works as well. Seems that from now on this line is gone from my log file, but I still get not thumbnail:

I reloaded the page and now it takes longer to load and before it loads there is a millisecond-long flash like there would be a reallocation of HTML elements but it quits and throws the same error where the thumbnail should be.

I also checked the limits.sh and it says: MW_CPU_LIMIT=0 MW_CGROUP= MW_MEM_LIMIT=0 MW_FILE_SIZE_LIMIT=0 MW_WALL_CLOCK_LIMIT=0

So these might not be the error as well and the Limits are set via command line laters othey would be overwriten as well. But to be srue I increased $wgMaxShellMemory to 809600 just to be sure. then i tried again - still no thumbnail:

now, when i search the filename of the pic, firemans_carry.png, it says this line as well: Title::getRestrictionTypes: applicable restrictions to Firemans Carry are {edit,move} Well i think this is some Mediawiki internate with user management permissions for this image, so I don't think it has anything to do with the problem.

I also find:

File::transform: Doing stat for mwstore://local-backend/local-thumb/d/de/Firemans_carry.png/120px-Firemans_carry.png

FileBackendStore::getFileStat: File mwstore://local-backend/local-thumb/d/de/Firemans_carry.png/120px-Firemans_carry.png does not exist.
