From 8b5d5f9652499103b966524e1c0ceef869e29eeb Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Mon, 20 Feb 2012 12:40:38 -0500 Subject: Make LLProcess post termination event to specified pump if desired. This way a caller need not spin on isRunning(); we can just listen for the requested termination event. Post a similar event containing error message if for any reason LLProcess::create() failed to launch the child. Add unit tests for both cases. --- indra/llcommon/llprocess.h | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) (limited to 'indra/llcommon/llprocess.h') diff --git a/indra/llcommon/llprocess.h b/indra/llcommon/llprocess.h index 06be0954c0..96a3dce5b3 100644 --- a/indra/llcommon/llprocess.h +++ b/indra/llcommon/llprocess.h @@ -158,7 +158,8 @@ public: args("args"), cwd("cwd"), autokill("autokill", true), - files("files") + files("files"), + postend("postend") {} /// pathname of executable @@ -184,6 +185,20 @@ public: * underlying implementation library doesn't support that. */ Multiple files; + /** + * On child-process termination, if this LLProcess object still + * exists, post LLSD event to LLEventPump with specified name (default + * no event).
