Plack down due to "GET http://swagger.io/v2/schema.json == Connect timeout"
Hi all, As some people have noticed, http://swagger.io/v2/schema.json is currently unavailable, and this is causing new instances of Plack workers to crash. (New instances can be created by starting Plack or by long-running workers to reach their end of life number of requests.) The issue is detailed at length in https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23653. I think the solution will be for Mason to a libjson-validator-perl package which contains a cached version of that file. Alternatively, I have copied the cached version into a patch and configured Koha to use that version instead of trying to go to http://swagger.io/v2/schema.json. I think that Mason distributing that updated package is probably the better solution, but I figure that it doesn't hurt to have options. I've tested my patch in koha-testing-docker and it worked well. Of course, while we wait for an updated package, you can also use the workaround that Mason has provided at https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23653#c11. The "cache" in question isn't a real cache, so it won't get invalidated. It will persist for years, so once the workaround is done, your server should be safe. But new installs and unattended servers will need a more automated solution.

hi Folks i've updated the 'libjson-validator-perl' package to include the cache dir to update the package... $ sudo apt update $ sudo apt install libjson-validator-perl run the following command, and confirm the result... $ apt-cache policy libjson-validator-perl libjson-validator-perl: Installed: 3.06+dfsg-1+koha1 Candidate: 3.06+dfsg-1+koha1 ... cheers, Mason
Thanks, Mason! I think Mason has released a newer version now 3.23+dfsg-1+koha1, which was needed for newer versions of Ubuntu, which used newer versions of libjson-validator-perl than 3.06. So the fix now should just be: apt-get update apt-get install libjson-validator-perl David Cook Systems Librarian Prosentient Systems 72/330 Wattle St Ultimo, NSW 2007 Australia Office: 02 9212 0899 Online: 02 8005 0595 -----Original Message----- From: Koha-devel <koha-devel-bounces@lists.koha-community.org> On Behalf Of Mason James Sent: Wednesday, 1 July 2020 1:32 PM To: 'Koha Devel' <koha-devel@lists.koha-community.org>; koha@lists.katipo.co.nz Subject: Re: [Koha-devel] Plack down due to "GET http://swagger.io/v2/schema.json == Connect timeout" On 1/07/20 2:39 pm, dcook@prosentient.com.au wrote:
