#2726: confusing logic on data preview formats

shevski — Sun, 22 Jul 2012 09:38:47 GMT

If a user enters the wrong format on a file that can be previewed - it simply won't be previewed (e.g. a CSV or XML file that can be filled in with JSON in format will just not work or check this

If I incorrectly edit format to one that data preview will try to preview it will work even for a format that it doesn't accept (sometimes) e.g. this PDF file I changed the metadata to HTML http://s031.okserver.org:2375/en/dataset/test-dataset/resource/9d27a9d9-36ec-460e-9edb-6dff7ba4fc28

#2859: Fix the build

icmurray — Thu, 16 Aug 2012 09:26:57 GMT

The requires files have been removed. These were required by buildkit.

We've lost the information regarding which packages were already in ubuntu repos, which conflicted and which were missing. But perhaps we can just package everything up.

Atom feeds have been implemented in core in #1593. The IATI-specific implementation can now be removed when IATI move to CKAN >= 1.6.1

#2485: Encourage leak containment by limiting the number of requests a CKAN process serves

nils.toedtmann — Fri, 01 Jun 2012 11:47:09 GMT

CKAN has memory leaks. They can be contained by limiting the time-to-live of a ckan process. An easy way to achieve this is to limit the number of requests a ckan server process can serve before it gets killed and replaced.

One should ...

research ways to limit requests-per-process with the different web servers (see below for a start);
explain these safeguards in the CKAN documentation and encourage users to apply them;
consider the helper script ckan-create-instance to generate Apache configs with WSGIDaemonProcess ... maximum-requests=XY being active instead of commented out. Or at least let it warn the user to use MaxRequestsPerChild;
Investigate current CKAN deployments whether they suffer from mem leaks, and if so contain them.

How to limit requests-per-process

Apache:
- Use WSGIDaemonProcess with maximum-requests=50 or whatever limit is appropriate. We did this sucessfully on datahub.io and the ckan farm
- (This need to be verified) Without WSGIDaemonProcess, MaxRequestsPerChild 50 should achieve the same.
nginx/supervisord: to be researched.
