Bug Description

Binary package hint: phatch

I have a rename action which is working fine on JPGs. When applied to RAW image files (Sony ARW format) the rename works ok for a few files but then crashes with the following error:

Error: Unable to open file: /xxxx/xxxxx/xxxxx/xxxx/xxxxx/DSC00786.ARW:
(12, 'Cannot allocate memory')

Monitoring the phatch process in top shows the memory utilisation increase as it works through a batch

Restarting the phatch with the same action on the same (remaining photos) and it continues with the image that caused an issue

Images not attached as multiple large files are required (can be sent on request)

Ubuntu 9.10
Phatch 0.2.4-1

Does the memory increase also happen with jpeg files? How much memory does your system have?

To debug I'll need the photo files as well. You can send them to me privately if you prefer.

Hey there Stani, I'm also experiencing this bug. I have a core2quad with 4 Gb of memory (3.9 Gb available, with a PAE-enabled kernel). I wanted to simply convert 432 Nikon (.NEF) files to jpeg after resizing. Symptoms are the same as julez's, memory usage climbing (currently 1.3 Gb used while only 32 files have been processed!), and once in a while, a file fails to convert, citing the cannot allocate memory error.

To some extent, I'm glad it's failing. I would have filled my 4 Gb of RAM. Why doesn't Phatch free memory after each image?

Further info:
- my RAM was far from full when this occured
- this is not specific to an image in particular. If I copy out the .NEF at which this occured, and try to run phatch on it, it works without problems.

Make 400 copies of this file and try to do batch resizing and exporting to jpeg on them.

Hi Matthieu,
Could you profile this? Phatch uses a subprocess with dcraw behind the scenes to open RAW images. Let me know if you are not interested.
