Use LLStringUtil::getenv() or getoptenv() whenever we fetch a string that will
be used as a pathname.
Use LLFile::tmpdir() instead of getenv("TEMP").
As an added extra-special bonus, finally clean up $TMP/llcontrol-test-zzzzzz
directories that have been accumulating every time we run a local build!
These are mostly things that were in fact erroneous, but accepted by older
compilers.
This changeset has not yet been built with Visual Studio 2013 or Linux gcc,
even with -std=c++11.
This changeset has not been built *without* -std=c++11. It should be used in
conjunction with a corresponding change to LL_BUILD_DARWIN_BASE_SWITCHES in
viewer-build-variables/variables.
This is a work in progress. We do not assert that this changeset completes the
work needed to turn on -std=c++11, even on the Mac.
We use boost::phoenix::placeholders::arg1 to imply a whole lambda expression,
replacing boost::lambda. But to bind a plain function in a more
straightforward way, seems classic boost::bind() works while
boost::phoenix::bind() does not.

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...

LL_INFOS("A", "B", "C") works, for example
fixed unit tests

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.
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.
Specifically:
Introduce ManageAPR class in indra/test/manageapr.h. This is useful for a
simple test program without lots of static constructors.
Extract NamedTempFile from llsdserialize_test.cpp to indra/test/
namedtempfile.h. Refactor to use APR file operations rather than platform-
dependent APIs.
Use NamedTempFile for llprocesslauncher_test.cpp.
Instead of low-level open(O_CREAT | O_EXCL) loop on all platforms, use
GetTempFileName() on Windows and mkstemp() elsewhere.
Don't append a final newline to NamedTempFile: use caller's data literally.
Tweak a couple comments.
Consider this pathname for llsdserialize_test.cpp:
C:\nats\indra\llcommon\tests\llsdserialize_test.cpp
Embed that in a Python string literal:
'C:\nats\indra\llcommon\tests\llsdserialize_test.cpp'
and you get a string containing:
C:
ats\indra\llcommon ests\llsdserialize_test.cpp
where the \n became a newline and the \t became a tab character.
Hopefully Python raw-string syntax r'C:\etc\etc' works better.
In this case, the Python code in question is being written from a C++ string
literal to a temp script file in a platform-dependent temp directory -- so the
Python __file__ value tells you nothing about the location of the repository
checkout. Embedding __FILE__ from the containing C++ source file works better.
And at that point, the Python logic needed to bring in the llsd module is big
enough to warrant capturing it in a separate string variable common to
multiple tests.
Write a sequence of LLSDSerialize::toNotation() calls separated by newlines to
a data file, then read lines and parse using llbase.llsd.parse(). Verify that
this produces expected data even when one item is a string containing newlines.
Generalize python() helper function to allow using any of the NamedTempFile
constructor forms.
Allow specifying expected Python rc (default 0) and use this to verify an
intentional sys.exit(17). This is better than previous sys.exit(0) test
because when, at one point, NamedTempFile failed to write file data, running
Python on an empty script file still terminates with rc 0. A nonzero rc
verifies that we've written the file, that Python is running it and that we're
retrieving its rc.
The only thing about NamedTempScript that was specific to script files was the
hardcoded ".py" extension. Renaming it to NamedTempFile with an explicit
extension argument addresses that.
Allow constructing NamedTempFile with either a std::string, as before, or an
expression of the form (lambda::_1 << some << stuff). If Linden's Boost
package included the Boost.Iostreams lib, we could even stream such an
expression directly to an ostream constructed around the fd. But oh well.
Seems Linden's Boost package and the viewer build might use different
settings of the /Zc:wchar_t switch.
Anyway, this implementation using open(O_CREAT | O_EXCL) should be more
robust. I'm surprised Boost.Filesystem doesn't seem to offer "create a unique
file"; all I found was "generate a random filename fairly likely to be unique."
On Windows, calling boost::filesystem::path::string() implicitly requests
code conversion between std::wstring (the boost::filesystem::path::string_type
selected on Windows) and std::string. At least for integration-test program,
that produces link errors. Use Linden's wstring_to_utf8str() instead.
It's wonderful that the Python interpreter will accept a whole multi-line
script as a composite -c argument... but because Windows command-line
processing is fundamentally flawed, we simply can't count on it for Windows.
Instead, accept script text, write a temporary script file in a system-
dependent temp directory, ask Python to run that script and delete the file.
Also, on Windows, use _spawnl(), much simpler than adding bizarre Windows wait
logic to LLProcessLauncher. Use LLProcessLauncher only on Mac & Linux, with
waitpid() to capture rc.
* turn llnamevalue_tut into a llmessage unit test
* turn llsdserialize_tut into a llcommon integration test
* re-enable the (quite slow) llsdserialize test on win32 now that it doesn't have to run on every recompile
* re-enable all llmessage unit tests on linux viewer builds
