json export doesn't work

[ertyz]

Wallabag 1.9.1
Ubuntu 14.04 (Linux 3.19 x64)
MySQL (MariaDB 10.1.9 x86_64) + php-fpm (5.5.9) + nginx (1.8.0)
500MB free ram and 2GB swap.

Import ~500 articles from pocket works fine for me, but

After I press export link, browser immediately gives me to download empty json file. It is always 0 bytes.

I didn't see anything in nginx or php5-fpm logs.
Does wallabag write own log files? What I need to try?

I was try to create new user account. Export work fine on it.

[ertyz]

I was trying:
in index.php

ini_set("memory_limit","512M");

in nginx.conf

keepalive_timeout 0;

and nothing happen.

Change in php-fpm.ini

log_level = debug

in config.inc.php

define ('DEBUG_POCHE', TRUE);

in nginx/error.wallabag.log i see only that debug message:

2015/12/14 06:06:30 [error] 2105#0: *37 FastCGI sent in stderr: "PHP message: DEBUG POCHE : storage type mysql" while reading response header from upstream, client: 172.17.1.2, server: , request: "GET /?export HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "mydomain.com", referrer: "http://mydomain.com/?view=config

This issue affects wallabag v1. This version won't move anymore.

I have the same issue. I want to move on to v2, but an export always gets me 0 bytes sized file. Is there some console version to export my data as json?

Same issue here.
I am OK with 1.x stop moving but you based your upgrade process on this 1.x export/2.x import.
Maybe you could take a look anyway.

We'll release a 1.9.2 version which will hopefully fix these issues.

@ymage you can follow this issue #1747

[jinnko]

1.9.2 doesn't resolve the issue. The documentation states the migration is as easy as export from v1 and import into v2, but that doesn't work and it takes a fair amount of digging to find this ticket and #1747.

The only method I found to work is benediktg's wallabag-migration script.

Effectively you're giving your loyal users and contributors a hard time. Not cool. I don't think anyone really minds what approach to take, as long as the documented approach works.
