From eae38f7d57be5576199294b501e082c6d850473c Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Fri, 12 Dec 2014 13:46:41 -0800 Subject: Eliminate use of boost::lambda with boost::function (Trac #10864). https://svn.boost.org/trac/boost/ticket/10864 I've used boost::lambda with boost::function in a number of creative ways over the years. But the clang 6 shipped with Xcode 6 seems to have somehow broken lambda + function in Boost 1.57. boost::phoenix is a partial workaround. Sadly, lambda's comma-operator overload doesn't seem to be supported, necessitating a couple ugly workarounds. With real lambdas now supported by current compilers, I'm sure the Boost community has little incentive to repair the lambda + function problem. Presumably we'll be able to use such features ourselves Real Soon Now... --- indra/llcommon/tests/llleap_test.cpp | 10 ++++---- indra/llcommon/tests/llsdserialize_test.cpp | 40 ++++++++++++++++------------- 2 files changed, 27 insertions(+), 23 deletions(-) (limited to 'indra/llcommon/tests') diff --git a/indra/llcommon/tests/llleap_test.cpp b/indra/llcommon/tests/llleap_test.cpp index 9ea822cb8d..653b043de4 100755 --- a/indra/llcommon/tests/llleap_test.cpp +++ b/indra/llcommon/tests/llleap_test.cpp @@ -17,7 +17,7 @@ // std headers // external library headers #include -#include +#include #include // other Linden headers #include "../test/lltut.h" @@ -109,7 +109,7 @@ namespace tut llleap_data(): reader(".py", // This logic is adapted from vita.viewerclient.receiveEvent() - boost::lambda::_1 << + boost::phoenix::placeholders::arg1 << "import re\n" "import os\n" "import sys\n" @@ -403,7 +403,7 @@ namespace tut AckAPI api; Result result; NamedTempFile script("py", - boost::lambda::_1 << + boost::phoenix::placeholders::arg1 << "from " << reader_module << " import *\n" // make a request on our little API "request(pump='" << api.getName() << "', data={})\n" @@ -441,7 +441,7 @@ namespace tut ReqIDAPI api; Result result; NamedTempFile script("py", - boost::lambda::_1 << + boost::phoenix::placeholders::arg1 << "import sys\n" "from " << reader_module << " import *\n" // Note that since reader imports llsd, this @@ -484,7 +484,7 @@ namespace tut ReqIDAPI api; Result result; NamedTempFile script("py", - boost::lambda::_1 << + boost::phoenix::placeholders::arg1 << "import sys\n" "from " << reader_module << " import *\n" // Generate a very large string value. diff --git a/indra/llcommon/tests/llsdserialize_test.cpp b/indra/llcommon/tests/llsdserialize_test.cpp index b5893135ea..afd4e7c8c1 100755 --- a/indra/llcommon/tests/llsdserialize_test.cpp +++ b/indra/llcommon/tests/llsdserialize_test.cpp @@ -46,9 +46,9 @@ typedef U32 uint32_t; #include "boost/range.hpp" #include "boost/foreach.hpp" #include "boost/function.hpp" -#include "boost/lambda/lambda.hpp" -#include "boost/lambda/bind.hpp" -namespace lambda = boost::lambda; +#include "boost/phoenix/bind/bind_function.hpp" +#include "boost/phoenix/core/argument.hpp" +using namespace boost::phoenix; #include "../llsd.h" #include "../llsdserialize.h" @@ -1612,6 +1612,20 @@ namespace tut "print 'Running on', sys.platform\n"); } + // helper for test<3> + static void writeLLSDArray(std::ostream& out, const LLSD& array) + { + BOOST_FOREACH(LLSD item, llsd::inArray(array)) + { + LLSDSerialize::toNotation(item, out); + // It's important to separate with newlines because Python's llsd + // module doesn't support parsing from a file stream, only from a + // string, so we have to know how much of the file to read into a + // string. + out << '\n'; + } + } + template<> template<> void TestPythonCompatibleObject::test<3>() { @@ -1639,26 +1653,16 @@ namespace tut " assert False, 'Too many data items'\n"; // Create an llsdXXXXXX file containing 'data' serialized to - // notation.
