[SOLVED] This feed URL goes in error (500)

Tiny Tiny RSS Support

Hi,

I am running Tiny Tiny RSS v17.12 (bb0a8e3) on my personal server (Ubuntu Server 17.10, Apache2, PostgreSQL 9).

Basically this URL feed goes in error 500:
http://www.telefonino.net/rss_master.asp

The URL works from Firefox.

This is the output of the debug:

[08:26:18/494] start
[08:26:18/494] local cache will not be used for this feed
[08:26:18/494] last unconditional update request: 2017-12-31 16:02:02

[08:26:18/494] source last modified:
[08:26:18/494] unable to fetch: HTTP/1.1 500 Internal Server Error [500]

The same error in https://fakecake.org/myfeedsucks/.

Do you have an idea?

Many thanks,

an idea: consider reading the error output

Hi fox,

thanks for the response.

I investigated and found that feed provider adds 500 error as response header, but the content is valid.
I print the headers returned in the ā€œfunction fetch_file_contentsā€ of the ā€œinclude/functions.phpā€ file:

HTTP/1.1 500 Internal Server Error
Cache-Control: private
Content-Length: 33637
Content-Type: text/xml
Expires: Tue, 02 Jan 2018 16:44:48 GMT
Server: Microsoft-IIS/7.0
Set-Cookie: ASPSESSIONIDQCRTBQDA=KCKMNOKBCCBAPDOLLAMGJLIK; path=/
X-Powered-By: ASP.NET
Date: Tue, 02 Jan 2018 16:29:47 GMT

Content-Length and Content-Type are valid, and payload is a regular XML.

I believe this is a very rare case, I donā€™t expect that tt-rss manages it. In the meanwhile I will arrange a workaround on my instance.

Many thanks,
g.

thereā€™s no facepalm big enough for this

Ok, I found this trivial workaround.

Change line 149 of the ā€œinclude/functions.phpā€ to:

define(ā€˜SELF_USER_AGENTā€™, ā€˜Wget/Tiny Tiny RSS/ā€™ . VERSION . ā€™ (http://tt-rss.org/)');

The ā€œWget/ā€ in the user agent name makes it work.

It never ceases to amaze me how poorly web admins can run their sites. :man_facepalming: Itā€™s amazing the internet works and even more so that as the human race weā€™re able to accomplish anything at all.

e: Is it just me or is Discourse showing a woman facepalming even though I picked
ā€œman_facepalmingā€? How ironicā€¦

did you just gender that emoji :shocked:

Even big companies like Oracle donā€™t get this right. Behold:

$ curl -H 'User-Agent: Tiny Tiny RSS/17.12 (4178dc8) (http://tt-rss.org/)' 'https://community.oracle.com/community/feeds/allcontent?community=13295'
File not found."
$ curl 'https://community.oracle.com/community/feeds/allcontent?community=13295'
File not found."
$ curl -H 'User-Agent: Tiny Tiny RSS/17.12 (4178dc8)' 'https://community.oracle.com/community/feeds/allcontent?community=13295'
<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:clearspace="http://www.jivesoftware.com/xmlns/jive/rss" version="2.0">
[...]

A URL in the User-Agent (or no User-Agent) breaks their feedsā€¦

I sent them an email, but I doubt theyā€™ll do anything about it. So I just set SELF_USER_AGENT in config.php.

I know sites that ban tt-rss intentionally :frowning:

10

Errā€¦ What seems rather strange.

11

Some admins are idiots :wink: Somehow they think tt-rss is some kind of evil monster hammering their precious sites. Mehā€¦

Maybe they identify as maleā€¦
