From aafb03b29f5166e8978931ad8b717be32d942836 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Tue, 7 Feb 2012 10:53:23 -0500 Subject: Convert LLProcess implementation from platform-specific to using APR. Include logic to engage Linden apr_procattr_autokill_set() extension: on Windows, magic CreateProcess() flag must be pushed down into apr_proc_create() level. When using an APR package without that extension, present implementation should lock (e.g.) SLVoice.exe lifespan to viewer's on Windows XP but probably won't on Windows 7: need magic flag on CreateProcess(). Using APR child-termination callback requires us to define state (e.g. LLProcess::RUNNING). Take the opportunity to present Status, capturing state and (if terminated) rc or signal number; but since most of the time all caller really wants is to log the outcome, also present status string, encapsulating logic to examine state and describe exited-with-rc vs. killed-by-signal. New Status logic may report clearer results in the case of a Windows child process killed by exception. Clarify that static LLProcess::isRunning(handle) overload is only for use when the original LLProcess object has been destroyed: really only for unit tests. We necessarily retain our original platform-specific implementations for just that one method. (Nonstatic isRunning() no longer calls static method.) Clarify log output from llprocess_test.cpp in a couple places. --- indra/llcommon/tests/llprocess_test.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'indra/llcommon/tests') diff --git a/indra/llcommon/tests/llprocess_test.cpp b/indra/llcommon/tests/llprocess_test.cpp index 4ad45bdf27..60ed12ad6a 100644 --- a/indra/llcommon/tests/llprocess_test.cpp +++ b/indra/llcommon/tests/llprocess_test.cpp @@ -630,7 +630,7 @@ namespace tut // Destroy the LLProcess, which should kill the child. } // wait for the script to terminate... one way or another. - while (LLProcess::isRunning(phandle)) + while (LLProcess::isRunning(phandle, "kill() script")) { sleep(1); } @@ -643,7 +643,7 @@ namespace tut template<> template<> void object::test<6>() { - set_test_name("autokill"); + set_test_name("autokill=false"); NamedTempFile from("from", "not started"); NamedTempFile to("to", ""); LLProcess::handle phandle(0); @@ -695,7 +695,7 @@ namespace tut outf << "go"; } // flush and close. // now wait for the script to terminate... one way or another. - while (LLProcess::isRunning(phandle)) + while (LLProcess::isRunning(phandle, "autokill script")) { sleep(1); } -- cgit v1.2.3
