Bug ID: 46210
Summary: explorer /desktop leaks atoms from DDE interface
Product: Wine
Version: 3.20
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: explorerframe
Assignee: wine-bugs at winehq.org
Reporter: ralf.habacker at freenet.de
Distribution: ---
explorer /desktop, started by wine as background process, initiate a DDE
interface (see
https://github.com/wine-mirror/wine/blob/master/programs/explorer/desktop.c#L993
and https://github.com/wine-mirror/wine/blob/master/dlls/shell32/dde.c#L483 for
details), but the DDE interface is not been free'd after main loop exit
(https://github.com/wine-mirror/wine/blob/master/programs/explorer/desktop.c#L1037)
resulting in leaked atoms.
On the first run the following DDE related atoms are created:
c018: ref=2 pinned=N hash=14 "Folders"
c019: ref=1 pinned=N hash=18 "Folders(0x 23)"
c01b: ref=2 pinned=N hash=17 "Progman"
c01c: ref=1 pinned=N hash=17 "Progman(0x 23)"
c01d: ref=2 pinned=N hash=29 "Shell"
c01e: ref=1 pinned=N hash=23 "Shell(0x 23)"
on the next start the following atoms are added and so one
c01f: ref=1 pinned=N hash=21 "Folders(0x 44)"
c027: ref=1 pinned=N hash=22 "Progman(0x 44)"
c028: ref=1 pinned=N hash=26 "Shell(0x 44)"
Because the DDE interface use atoms unique for each session, each run leaks
three atoms
