Hang on TT-RSS v18.8 (79c5035)

[Jakob]

Hi, I'm trying to connect to a TT-RSS instance (v18.8 (79c5035)), but whenever I update, Elfeed gets stuck at 0 jobs pending, 1 active... and Error running timer ‘elfeed-curl--call-callback’: (void-function string-empty-p) appears in *Messages*.

Relevant contents of init.el:

(require 'elfeed-protocol)
(setq elfeed-feeds (list "ttrss+https://jakob:[REDACTED]@rss.tildeverse.org"))
(elfeed-protocol-enable)

Contents of *elfeed-log*:

TT-RSS v17.x test passed before, I will try to find a docker image for v18.8 to reproduce your issue later.

[fasheng]

Hi, I didn't reproduce your issue finally. Here is my environment:

• emacs 26.1
• elfeed 3.1.0
• elfeed-protocol 0.5.7
• TT-RSS v18.12 (docker image linuxserver/tt-rss:154 which only owns the default "Tiny Tiny RSS: Forum" feed)
• emacs full config

  (setq elfeed-log-level 'debug)
  (setq elfeed-use-curl t)
  (elfeed-set-timeout 36000)
  (setq elfeed-feeds (list "ttrss+http://admin:password@localhost"))
  (elfeed-protocol-enable)

And the full log for first update operation:

You could have a try again with my environment to see if it works.

So I tried again with (setq elfeed-use-curl nil) and realized that I totally misinterpreted the error in my report. Really, the answer was staring me right in the eyes: error in process filter: Symbol’s function definition is void: string-empty-p. string-empty-p wasn't defined. So I defined a string-empty-p and suddenly everything started working.

A little bit of digging reveals that string-empty-p is provided by subr-x, which wasn't loaded. I added the require in #14.

Thanks, merged now, and will release new version 0.5.8 later.
