From f0dbb878337082d3f581874c12e6df2f4659a464 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Fri, 20 Jan 2012 18:10:40 -0500 Subject: Per Richard, replace LLProcessLauncher with LLProcess. 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/newview/llexternaleditor.cpp | 73 +++++++++++++++++++------------------- 1 file changed, 37 insertions(+), 36 deletions(-) (limited to 'indra/newview/llexternaleditor.cpp') diff --git a/indra/newview/llexternaleditor.cpp b/indra/newview/llexternaleditor.cpp index ed1d7e860a..ba58cd8067 100644 --- a/indra/newview/llexternaleditor.cpp +++ b/indra/newview/llexternaleditor.cpp @@ -29,6 +29,9 @@ #include "lltrans.h" #include "llui.h" +#include "llprocess.h" +#include "llsdutil.h" +#include // static const std::string LLExternalEditor::sFilenameMarker = "%s"; @@ -45,19 +48,8 @@ LLExternalEditor::EErrorCode LLExternalEditor::setCommand(const std::string& env return EC_NOT_SPECIFIED; } - // Add the filename marker if missing. - if (cmd.find(sFilenameMarker) == std::string::npos) - { - cmd += " \"" + sFilenameMarker + "\""; - llinfos << "Adding the filename marker (" << sFilenameMarker << ")" << llendl; - } - string_vec_t tokens; - if (tokenize(tokens, cmd) < 2) // 2 = bin + at least one arg (%s) - { - llwarns << "Error parsing editor command" << llendl; - return EC_PARSE_ERROR; - } + tokenize(tokens, cmd); // Check executable for existence. std::string bin_path = tokens[0]; @@ -68,51 +60,60 @@ LLExternalEditor::EErrorCode LLExternalEditor::setCommand(const std::string& env } // Save command. - mProcess.setExecutable(bin_path); - mArgs.clear(); + mProcessParams["executable"] = bin_path; + mProcessParams["args"].clear(); for (size_t i = 1; i < tokens.size(); ++i) { - if (i > 1) mArgs += " "; - mArgs += "\"" + tokens[i] + "\""; + mProcessParams["args"].append(tokens[i]); + } + + // Add the filename marker if missing. + if (cmd.find(sFilenameMarker) == std::string::npos) + { + mProcessParams["args"].append(sFilenameMarker); + llinfos << "Adding the filename marker (" << sFilenameMarker << ")" << llendl; + } + + llinfos << "Setting command [" << bin_path; + BOOST_FOREACH(const std::string& arg, llsd::inArray(mProcessParams["args"])) + { + llcont << " \"" << arg << "\""; } - llinfos << "Setting command [" << bin_path << " " << mArgs << "]" << llendl; + llcont << "]" << llendl; return EC_SUCCESS; } LLExternalEditor::EErrorCode LLExternalEditor::run(const std::string& file_path) { - std::string args = mArgs; - if (mProcess.getExecutable().empty() || args.empty()) + if (mProcessParams["executable"].asString().empty() || ! mProcessParams["args"].size()) { llwarns << "Editor command not set" << llendl; return EC_NOT_SPECIFIED; } - // Substitute the filename marker in the command with the actual passed file name. - LLStringUtil::replaceString(args, sFilenameMarker, file_path); - - // Split command into separate tokens. - string_vec_t tokens; - tokenize(tokens, args); + // Copy params block so we can replace sFilenameMarker + LLSD params(mProcessParams); - // Set process arguments taken from the command. - mProcess.clearArguments(); - for (string_vec_t::const_iterator arg_it = tokens.begin(); arg_it != tokens.end(); ++arg_it) + // Substitute the filename marker in the command with the actual passed file name. + LLSD& args(params["args"]); + for (LLSD::array_iterator ai(args.beginArray()), aend(args.endArray()); ai != aend; ++ai) { - mProcess.addArgument(*arg_it); + std::string sarg(*ai); + LLStringUtil::replaceString(sarg, sFilenameMarker, file_path); + *ai = sarg; } // Run the editor. - llinfos << "Running editor command [" << mProcess.getExecutable() + " " + args << "]" << llendl; - int result = mProcess.launch(); - if (result == 0) + llinfos << "Running editor command [" << params["executable"]; + BOOST_FOREACH(const std::string& arg, llsd::inArray(params["args"])) { - // Prevent killing the process in destructor (will add it to the zombies list). - mProcess.orphan(); + llcont << " \"" << arg << "\""; } - - return result == 0 ?

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. However, it's excellent that the same LLProcess::create() method can accept either LLProcess::Params or a properly-constructed LLSD block. --- indra/llcommon/tests/llprocess_test.cpp | 26 ++++++++--------- indra/llcommon/tests/llsdserialize_test.cpp | 6 ++-- indra/llplugin/llpluginprocessparent.cpp | 28 +++++++++--------- indra/llplugin/llpluginprocessparent.h | 12 ++++---- indra/newview/llexternaleditor.cpp | 33 ++++++++++++---------- indra/newview/llexternaleditor.h | 5 ++-- .../updater/llupdateinstaller.cpp | 12 ++++---- 7 files changed, 62 insertions(+), 60 deletions(-) (limited to 'indra/newview/llexternaleditor.cpp') diff --git a/indra/llcommon/tests/llprocess_test.cpp b/indra/llcommon/tests/llprocess_test.cpp index 55e22abd81..405540e436 100644 --- a/indra/llcommon/tests/llprocess_test.cpp +++ b/indra/llcommon/tests/llprocess_test.cpp @@ -107,8 +107,8 @@ struct PythonProcessLauncher const char* PYTHON(getenv("PYTHON"));
