Causes

  • One cause was fixed in JIRA 6.1 and later.  This bug resulted in null values in the mimetype column of the fileattachment table:  JRA-29357 - Getting issue details... STATUS  
  • There is also a known defect in older versions of the third-party JIRA Python Library which was not setting the right mime type for attachments added via REST API.

Resolution 1

Use this SQL to verify this is the problem you're having:

SELECT *
FROM fileattachment
WHERE mimetype IS NULL;

If results are returned there are attachments with NULL for their mimetype that can be fixed.

Always back up your data before performing any modification to the database. If possible, try your modifications on a test server.

First, list all file extensions for attachments with no mime type:

Postgres 
SELECT DISTINCT
  count(*) as occurrences,
  substring(filename from '\.(?!.*\.).*$') AS extension
FROM fileattachment
WHERE mimetype IS NULL OR mimetype = ''
GROUP BY extension
ORDER BY extension;
MySQL 
SELECT DISTINCT
  count(*) as occurrences,
  substring_index(filename, '.', -1) AS extension
FROM fileattachment
WHERE mimetype IS NULL OR mimetype = ''
GROUP BY extension
ORDER BY extension;

Once you choose appropriate MIME types for all the broken attachments you can fix them. Here's an example for GIF images, modify it for each MIME type you determine from the file extensions.

Postgres 
UPDATE fileattachment
SET mimetype = 'image/gif'
WHERE mimetype IS NULL OR mimetype = ''
  AND substring(filename from '\.(?!.*\.).*$') = 'gif';
MySQL 
UPDATE fileattachment
SET mimetype = 'image/gif'
WHERE mimetype IS NULL OR mimetype = ''
  AND substring_index(filename, '.', -1) = 'gif';

NOTE: Some attachment file names won't have a "dot three" extension in the name. These must be reviewed one at a time to determine the correct MIME type. Alternatively, you could set mimetype to "text/plain" for these files so they can be downloaded and fixed by consumers.

Postgres 
SELECT *
FROM fileattachment
WHERE mimetype IS NULL OR mimetype = ''
  AND length(substring(filename from '\.(?!.*\.).*$')) > 4
ORDER BY filename;
MySQL 
SELECT *
FROM fileattachment
WHERE mimetype IS NULL OR mimetype = ''
  AND length(substring_index(filename, '.', -1)) > 4
ORDER BY filename;


NOTE: The problem may still occur after updating the fileattachment data until you upgrade to JIRA 6.1 or above or the latest version of the JIRA application Python Library.

Resolution 2

(info) Grant all Operating Systems permissions for the user running JIRA to access the JIRA-home and JIRA-install directories and also full access on the attachments directory.
