From 14ddc6474a0ae83db8d034b00138289fb15e41b7 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 23 Feb 2012 13:41:26 -0500 Subject: Tighten up LLProcess pipe support, per Richard's code review. Clarify wording in some of the doc comments; be a bit more explicit about some of the parameter fields. Make some query methods 'const'. Change default LLProcess::ReadPipe::getLimit() value to 0: don't post any incoming data with notification event unless caller requests it. But do post pertinent FILESLOT in case caller reuses same listener for both stdout and stderr. Use more idiomatic, readable syntax for accessing LLProcess::Params data. --- indra/llcommon/tests/llprocess_test.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'indra/llcommon/tests') diff --git a/indra/llcommon/tests/llprocess_test.cpp b/indra/llcommon/tests/llprocess_test.cpp index fe599e7892..d7feddd26b 100644 --- a/indra/llcommon/tests/llprocess_test.cpp +++ b/indra/llcommon/tests/llprocess_test.cpp @@ -696,7 +696,7 @@ namespace tut "syntax_error:\n"); py.mParams.files.add(LLProcess::FileParam()); // inherit stdin py.mParams.files.add(LLProcess::FileParam()); // inherit stdout - py.mParams.files.add(LLProcess::FileParam("pipe")); // pipe for stderr + py.mParams.files.add(LLProcess::FileParam().type("pipe")); // pipe for stderr py.run(); ensure_equals("Status.mState", py.mPy->getStatus().mState, LLProcess::EXITED); ensure_equals("Status.mData", py.mPy->getStatus().mData, 1); @@ -1088,6 +1088,8 @@ namespace tut py.launch(); std::ostream& childin(py.mPy->getWritePipe(LLProcess::STDIN).get_ostream()); LLProcess::ReadPipe& childout(py.mPy->getReadPipe(LLProcess::STDOUT)); + // lift the default limit; allow event to carry (some of) the actual data + childout.setLimit(20); // listen for incoming data on childout EventListener listener(childout.getPump()); // also listen with a function that prompts the child to continue -- cgit v1.2.3
