Bug description:
Mahara: 18.04
OS: Linux
DB: Postgres
Browser: n/a
Cron fails (and is therefore locked) when one of the rss feeds has an invalid
ssl certificate.
The cron job calls lib/web.php::mahara_http_request() from
blocktype/externalfeed/lib.php::parse_feed()
The following error results:
[WAR] 63 (lib/web.php:4425) Curl error: 60: SSL certificate problem: unable
to get local issuer certificate
Call stack (most recent first):
* log_message("Curl error: 60: SSL certificate problem: unable to...", 8,
true, true) at /var/www/mahara/htdocs/lib/errors.php:95
* log_warn("Curl error: 60: SSL certificate problem: unable to...") at
/var/www/mahara/htdocs/lib/web.php:4425
* mahara_http_request(array(size 3), false) at
/var/www/mahara/htdocs/blocktype/externalfeed/lib.php:421
*
PluginBlocktypeExternalfeed::parse_feed("http://www.safeworkaustralia.gov.au/sites/SWA/medi...";,
"0", "", "********") at
/var/www/mahara/htdocs/blocktype/externalfeed/lib.php:336
* PluginBlocktypeExternalfeed::refresh_feeds() at
/var/www/mahara/htdocs/lib/mahara.php:1809
* call_static_method("PluginBlocktypeExternalfeed", "refresh_feeds") at
/var/www/mahara/htdocs/lib/cron.php:115
[WAR] 63 (blocktype/externalfeed/lib.php:336) error in
/blocktype/externalfeed/lib.php line 428. error:SSL certificate problem: unable
to get local issuer certificate
[WAR] 63 (lib/errors.php:536) [Error]: Wrong parameters for
MaharaException([string $message [, long $code [, Throwable $previous = NULL]]])
Call stack (most recent first):
* exception(object(Error)) at Unknown:0
I had added extra debugging statements to see the error:
[WAR] 63 (blocktype/externalfeed/lib.php:336) error in
/blocktype/externalfeed/lib.php line 428. error:SSL certificate
problem: unable to get local issuer certificate
Mahara then raises a MaharaException with the error (SSL certificate problem:
unable to get local issuer certificate) as the code. But, it's not an integer
so it fails with:
[WAR] 63 (lib/errors.php:536) [Error]: Wrong parameters for
MaharaException([string $message [, long $code [, Throwable $previous
= NULL]]])
We need to check if the error coming back is a number or string. If number,
pass it as the code in the MaharaException. Otherwise, append it to the text of
the error message so the data is not lost.
We found this when upgrading from 17.04 to 18.04. This issue is present in
17.04 as well.
