I have moved Timestore's database tree via its command line option D ( https://github.com/TrystanLea/timestore/blob/master/src/main.c#L57 ) to a new path.

Timestore nicely creates a new adminkey and also its tsdb files in the new path but emoncms was never picking up any data. Being new to emoncms I have been fighting badly with this one until I realized that emoncms's timestore module has the path to the database tree hardcoded.

root@emoncms /var/www/emoncms # fgrep -r /var/lib/timestore/ *
Modules/feed/engine/Timestore.php:    $primaryfeedname = "/var/lib/timestore/$feedname";
Modules/feed/engine/Timestore.php:    $meta = fopen("/var/lib/timestore/$feedname", 'rb');
Modules/feed/engine/Timestore.php:    $meta = fopen("/var/lib/timestore/$feedname", 'rb');
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_0_.dat");
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_1_.dat");
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_2_.dat");
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_3_.dat");
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_4_.dat");
Modules/feed/engine/Timestore.php:    $size += filesize("/var/lib/timestore/".str_pad($feedid, 16, '0', STR_PAD_LEFT)."_5_.dat");
readme.md:    cat /var/lib/timestore/adminkey.txt

May I propose to add the database tree path to the emoncms settings.php to make it configurable.

Side note:

Timestore tries to switch to the timestore user after start. But neither the install guide nor the install script mention this. Is this on purpose?

Otherwise we could just add something like

useradd -s /usr/sbin/nologin timestore

chown timestore /var/lib/timestore

to the install script.
