From e39c2beaae2daf619ac8a553018d2f8265fa2eb9 Mon Sep 17 00:00:00 2001 From: Wim Taymans Date: Fri, 11 Nov 2005 16:34:15 +0000 Subject: [PATCH] gst/gstpad.c: While checking the flag for reentrancy in the gstcaps function is nice to detect recursive invocations,... Original commit message from CVS: * gst/gstpad.c: (gst_pad_get_caps), (gst_pad_peer_get_caps): While checking the flag for reentrancy in the gstcaps function is nice to detect recursive invocations, it also makes it impossible to call getcaps from multiple threads, which must be possible. So, checking for recursive calls has to go. --- ChangeLog | 8 ++++++++ gst/gstpad.c | 27 +-------------------------- 2 files changed, 9 insertions(+), 26 deletions(-) diff --git a/ChangeLog b/ChangeLog index 371201a..36285c7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,11 @@ +2005-11-11 Wim Taymans + + * gst/gstpad.c: (gst_pad_get_caps), (gst_pad_peer_get_caps): + While checking the flag for reentrancy in the gstcaps function + is nice to detect recursive invocations, it also makes it + impossible to call getcaps from multiple threads, which must be + possible.
