LLProcessLauncher had the somewhat fuzzy mandate of (1) accumulating parameters with which to launch a child process and (2) sometimes tracking the lifespan of the ensuing child process. But a valid LLProcessLauncher object might or might not have ever been associated with an actual child process. LLProcess specifically tracks a child process. In effect, it's a fairly thin wrapper around a process HANDLE (on Windows) or pid_t (elsewhere), with lifespan management thrown in. A static LLProcess::create() method launches a new child; create() accepts an LLSD bundle with child parameters. So building up a parameter bundle is deferred to LLSD rather than conflated with the process management object. Reconcile all known LLProcessLauncher consumers in the viewer code base, notably the class unit tests. --- indra/llcommon/CMakeLists.txt | 6 +- indra/llcommon/llprocess.cpp | 338 ++++++++++ indra/llcommon/llprocess.h | 106 +++ indra/llcommon/llprocesslauncher.cpp | 394 ----------- indra/llcommon/llprocesslauncher.h | 107 --- indra/llcommon/tests/llprocess_test.cpp | 706 ++++++++++++++++++++ indra/llcommon/tests/llprocesslauncher_test.cpp | 718 --------------------- indra/llcommon/tests/llsdserialize_test.cpp | 13 +- indra/llplugin/llpluginprocessparent.cpp | 47 +- indra/llplugin/llpluginprocessparent.h | 10 +- indra/newview/llexternaleditor.cpp | 73 +-- indra/newview/llexternaleditor.h | 5 +- .../updater/llupdateinstaller.cpp | 20 +- 13 files changed, 1238 insertions(+), 1305 deletions(-) create mode 100644 indra/llcommon/llprocess.cpp create mode 100644 indra/llcommon/llprocess.h delete mode 100644 indra/llcommon/llprocesslauncher.cpp delete mode 100644 indra/llcommon/llprocesslauncher.h create mode 100644 indra/llcommon/tests/llprocess_test.cpp delete mode 100644 indra/llcommon/tests/llprocesslauncher_test.cpp (limited to 'indra/llplugin') diff --git a/indra/llcommon/CMakeLists.txt b/indra/llcommon/CMakeLists.txt index 2c376bb016..e2af7265aa 100644 --- a/indra/llcommon/CMakeLists.txt +++ b/indra/llcommon/CMakeLists.txt @@ -74,7 +74,7 @@ set(llcommon_SOURCE_FILES llmortician.cpp lloptioninterface.cpp llptrto.cpp - llprocesslauncher.cpp + llprocess.cpp llprocessor.cpp llqueuedthread.cpp llrand.cpp @@ -197,7 +197,7 @@ set(llcommon_HEADER_FILES llpointer.h llpreprocessor.h llpriqueuemap.h - llprocesslauncher.h + llprocess.h llprocessor.h llptrskiplist.h llptrskipmap.h @@ -328,7 +328,7 @@ if (LL_TESTS) LL_ADD_INTEGRATION_TEST(reflection "" "${test_libs}") LL_ADD_INTEGRATION_TEST(stringize "" "${test_libs}") LL_ADD_INTEGRATION_TEST(lleventdispatcher "" "${test_libs}") - LL_ADD_INTEGRATION_TEST(llprocesslauncher "" "${test_libs}" + LL_ADD_INTEGRATION_TEST(llprocess "" "${test_libs}" "${PYTHON_EXECUTABLE}" "${CMAKE_CURRENT_SOURCE_DIR}/tests/setpython.py") LL_ADD_INTEGRATION_TEST(llstreamqueue "" "${test_libs}") diff --git a/indra/llcommon/llprocess.cpp b/indra/llcommon/llprocess.cpp new file mode 100644 index 0000000000..8c0caca680 --- /dev/null +++ b/indra/llcommon/llprocess.cpp @@ -0,0 +1,338 @@ +/** + * @file llprocess.cpp + * @brief Utility class for launching, terminating, and tracking the state of processes. + * + * $LicenseInfo:firstyear=2008&license=viewerlgpl$ + * Second Life Viewer Source Code + * Copyright (C) 2010, Linden Research, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; + * version 2.1 of the License only. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Using a Params block gives compile-time checking against attribute typos. One might inadvertently set myLLSD["autofill"] = false and only discover it when things behave strangely at runtime; but trying to set myParams.autofill will produce a compile error.
