Hi,
I am setting up some automation with darktable-cli to generate some foto
collections. I thought using good old make (the tool to automate
compilations etc) would be a good idea, but I found out, that darktable-cli
changes the modification time of the xmp sidecar files.
for illustration:
joerg@dilbert:~/tmp$ date
So 5. Okt 10:57:10 CEST 2014
joerg@dilbert:~/tmp$ ls -la
insgesamt 19180
drwx------ 2 joerg joerg 4096 Okt 5 10:57 .
drwxrwxr-x 172 joerg joerg 20480 Okt 5 09:49 ..
-rw-rw-r-- 1 joerg joerg 19606386 Okt 5 10:56 IMG_6905.CR2
-rw-rw-r-- 1 joerg joerg 4656 Okt 5 10:56 IMG_6905.CR2.xmp
joerg@dilbert:~/tmp$ date
So 5. Okt 10:57:19 CEST 2014
joerg@dilbert:~/tmp$ darktable-cli IMG_6905.CR2 IMG_6905.CR2.xmp
IMG_6905.jpg --width 1000 --height 1000
[export_job] exported to `IMG_6905.jpg'
joerg@dilbert:~/tmp$ ls -la
insgesamt 19844
drwx------ 2 joerg joerg 4096 Okt 5 10:57 .
drwxrwxr-x 172 joerg joerg 20480 Okt 5 09:49 ..
-rw-rw-r-- 1 joerg joerg 19606386 Okt 5 10:56 IMG_6905.CR2
-rw-rw-r-- 1 joerg joerg 4674 Okt 5 10:57 IMG_6905.CR2.xmp
-rw-rw-r-- 1 joerg joerg 679573 Okt 5 10:57 IMG_6905.jpg
you can see, that the modifiaction time for the xmp file was updated from
10:56 to 10:57.
It seems to be no problem, if DT can't write the xmp file, because file
permissions forbit it:
joerg@dilbert:~/tmp$ chmod 440 IMG_6905.CR2.xmp
joerg@dilbert:~/tmp$ rm IMG_6905.jpg
joerg@dilbert:~/tmp$ darktable-cli IMG_6905.CR2 IMG_6905.CR2.xmp
IMG_6905.jpg --width 1000 --height 1000
[export_job] exported to `IMG_6905.jpg'
joerg@dilbert:~/tmp$ ls -la
insgesamt 19844
drwx------ 2 joerg joerg 4096 Okt 5 10:59 .
drwxrwxr-x 172 joerg joerg 20480 Okt 5 09:49 ..
-rw-rw-r-- 1 joerg joerg 19606386 Okt 5 10:56 IMG_6905.CR2
-r--r----- 1 joerg joerg 4674 Okt 5 10:57 IMG_6905.CR2.xmp
-rw-rw-r-- 1 joerg joerg 679573 Okt 5 10:59 IMG_6905.jpg
the jpeg file is OK.
Would a patch to write the sidecars back to disk, only if the have changes
be accepted?
regards
Joerg
