  • Last updated: 2018-01-08
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

After this change the non-threaded versions of OpenLDAP libraries will not be shipped any more. Instead, these file will rather symlink to their threaded representatives (i.e. libldap -> libldap_r, etc.). This has been previously discussed in [Bugzilla] and other distributions where this change already happened. Upstream still supports non-threaded versions of their libraries as these might be used on processors where threads are not supported. However, when these two versions happen to be loaded at the same time (as discussed about Curl in the Bugzilla) symbol names overlap which may result in unpredictable behaviour. As the most convenient solution arises the one proposed hereby.

Benefit to Fedora

No potential unexpected issues due to symbol overlap.

Scope

  • Proposal owners: update SPEC file so that some files are not shipped and replaced with appropriate symlinks.
  • Other developers: None. Issues should not occur.
  • Policies and guidelines: None.
  • Trademark approval: (not needed for this Change)

Upgrade/compatibility impact

No issues should occur.


How To Test

User Experience

User should not notice anything.

Dependencies

None.


Contingency Plan

  • Contingency mechanism: Revert the change.
  • Contingency deadline: beta freeze.
  • Blocks release? No.
  • Blocks product? No.

Release Notes
