oldest_article not working, all RSS items downloaded instead

khromov · 07-09-2012, 06:02 AM

Having issues with ebook-convert not honoring the oldest_article attribute in recepies. Instead, all artices in the feed are downloaded.

I am running this on a Raspberry Pi (which has no hardware clock), so I thought maybe something was wrong with the dates, but I have tested both linux date command and python datetime and they both work fine. (See examples below.)

Any ideas as to what might be causing oldest_article to not work?

Edit: Added python version below.

Date output (Linux)

Code:

root@raspberrypi:~# date
Mon Jul  9 11:54:30 CEST 2012

Date output (Python using datetime.datetime.now())

Code:

Current date and time using str method of datetime object:
2012-07-09 11:55:16.431494

Version info:

Code:

root@raspberrypi:~/calibre# ebook-convert --version
ebook-convert (calibre 0.8.51)

Python version:

Code:

root@raspberrypi:~# python --version
Python 2.7.3rc2

Example of affected recipe:
http://bazaar.launchpad.net/~kovid/c.../idg_se.recipe

Command being run:

Code:

ebook-convert IDG.recipe test.mobi

ebook-convert uses the exact same code as the calibre GUI. There is something on your system that is causing this. What that is is impossible to say offhand, you will need to run calibre from source and stick print statements in various places in feeds/__init__.py to see what is happening.

One basic check is:

calibre-debug -c "from calibre.utils.date import utcnow; print utcnow()"

I have never run the GUI, this is a headless setup, but I guess that alone can't cause this problem.

Thanks, I was looking for this kind of answer, unfortunately this command seems to work, unless you can spot something amiss:

Code:

root@raspberrypi:~# calibre-debug -c "from calibre.utils.date import utcnow; print utcnow()"

Thanks for the tip, will try to set a development environment up.
