Jira 8.20.x gotcha: lost notifications

Jeff Turner posted on Nov 01, 2021

This weekend I upgraded a Jira instance from one LTS release to the next (8.13.1 to 8.20.1).  Everything appeared to go well, but shortly afterwards users started complaining: Jira is not emailing certain users. I checked, and sure enough: there's a situation where Jira 8.13.x and all prior releases would email, but Jira 8.20.x will not. Specifically, this affects users like this one, who are not in a group like jira-users blessed with 'Application access': image2021-11-1_23-28-0.…

Confluence 'Missing attachments' images

Jeff Turner posted on Oct 22, 2020

Sometimes Confluence users will report that their attachments have disappeared, with an 'Unknown Attachment' placeholder image showing: image2020-10-22_22-41-4.png The weird thing is that the attachment(s) do actually exist, attached to the page. It's just the image reference in the page that's broken. If you view the Confluence page source through the Source Editor plugin https://marketplace.atlassian.com/apps/1210722/confluence-source-editor?hosting=server&tab=overview,…

Tweaking Jira's Garbage Collection flags for use with GCViewer

Jeff Turner posted on Sep 24, 2020

The takeaway from this article is that, if you run Jira Server, there is a config tweak you really ought to make, to allow the use of GCViewer https://github.com/chewiebug/GCViewer to debug any future garbage collection problems: For Jira, edit /opt/atlassian/jira/bin/set-gc-params.sh and add make this change: diff --git a/bin/set-gc-params.sh b/bin/set-gc-params.sh --- a/bin/set-gc-params.sh +++ b/bin/set-gc-params.sh @@ -6,7 +6,7 @@ then # In Java 9,…

  • JIRA-backed LDAP — Notes on my attempts to have OpenLDAP use JIRA itself as its backing database, through the back-sql https://linux.die.net/man/5/slapd-sql OpenLDAP backend. This allows LDAP-enabled applications to reuse JIRA user credentials.
    • A guide to setting up Postgres-backed OpenLDAP with the back-sql backend — OpenLDAP is typically backed by a LMDB database (mdb). However it's backing datastore is actually pluggable. One of the most intriguing backends is back-sql https://www.openldap.org/doc/admin24/backends.html#SQL, which allows LDAP data to be fetched from an ODBC (SQL) datasource. This lets us add a LDAP facade on top of database-backed applications, like JIRA and Confluence.

  • JIRA Sprint Capacity Planner — Planning a sprint in JIRA Agile involves assigning issues. You want to spread the load fairly, not overburdening or underburdening workers. To complicate matters, some issues take longer than others (with more Story Points or greater Time Estimate), and the capacity of each worker varies per week, as they may have time off or other responsibilities.
  • Jira tinkerers beware: Tomcat does not serve raw files correctly, causing browser hangs — This page is for anyone who has been tempted to add files (e.g. js, css) into JIRA's atlassian-jira/ directory. It may come as a surprise, but JIRA suffers from the most basic of bugs: it doesn't serve static files correctly. More specifically, if Tomcat serves the file with gzip compression, the Content-Length: header is incorrectly set.
