Release Notes

python-ldap/python-ldap (python-ldap)

v3.4.8: 3.4.8

Compare Source

Fixes:

• Plugged memory and reference leaks at error-handling time (#​40, #​617, #​619,
  #​620, #​621, #​622, #​632)
• VLV control now honours contextID passed in (#​618)
• ldapurl now correctly escapes when emitting a HTML anchor (#​628)
• _ldap.str2dn now handles empty string correctly (#​549)
• handle server-sent invalid UTF-8 correctly (by throwing an error) (#​624)
• corrected ldap.functions export list to remove long gone items

Doc:

• fd ownership has now been clarified - if providing an fd to set up a new
  LDAPObject, it is now owned and managed by the module, do not close it
  yourself (#​575)
• clarifications on handling EINTR -> use OPT_RESTART (#​242)
• clarified build dependencies (#​569)
• clarified OPT_CLIENT_CONTROLS/OPT_SERVER_CONTROLS (#​639)

Infrastructure:

• Build requirement pinned to setuptools>=61: older setuptools ignores
  the PEP 621 [project] table and produces an sdist with broken metadata
  (Name: unknown), which made pip silently fall back to ancient releases
  when building 3.4.5 from source (#​616). Old environments now fail with a
  clear resolver error instead.
• Removed the [install] section (compile/optimize) from
  setup.cfg; it caused bdist_wheel to embed __pycache__
  byte-code files in published wheels (#​615).
