Chrome 14 Beta Integrates Native Client 209

Posted by Soulskill from the going-native dept.
derGoldstein writes "This year Microsoft kept signaling that it's going back to lower-level code with a C++ renaissance. It would give C++ programmers the same priority that was, up until now, reserved for .Net programmers. They even launched a new show about it on their Channel9. Now Google wants to appeal to native programmers with their Native Client for Chrome. It seems the two companies want to cover both the higher-level JavaScript and lower-level C/C++. I dare hope this will give seasoned C/C++ programmers a place alongside JavaScript programmers at the web development table."

    I dare hope this will give seasoned C/C++ programmers a place alongside JavaScript programmers at the web development table.

    Yeah, nothing thrills me more than the prospect of a language with absolutely no memory safety or bounds checking being exposed to the public Internet. What could possibly go wrong?

      you mean like when the browser itself is exploited in the same manner by crafted javascript?

      the only way to truly secure 'the web' is to remove the ability to script browsers beyond basic formatting that can be done in html.

      I suggest that you read about how NaCl actually works before commenting. It is a sandbox for native code. It doesn't run just any code, either - there are certain constraints in place which make it possible to verify the result for safety. "Safety" here means that code cannot break out of the sandbox - it can, of course, still crash itself, but that would be fully isolated, and cannot be used in the usual manner as a privilege escalation exploit.

        Or that's the idea, [google.com] anyway.

      • I find myself a little perturbed by the fact that they're using code verification and sandboxing. If the sandboxing is solid --- which isn't actually that hard; any modern operating system already does this as a matter of course as part of the process model --- then the verification shouldn't be necessary.

          The crazy thing is that process isolation as provided by operating systems is relying heavily on hardware support. Most processors only have a kernel mode and a user mode and the mode switching is a part of what isolates processes. The 80386 was cleverly designed to have 4 modes, called rings, 0 to 3, where each inner ring would have more privileges than the outer rings. This was at a time where most of the OS makers ended up looking at this design and scratching their heads in wonder, having no idea how to

You can construct grammar trees and fill them online. During my CS study we built such realtime parsers in one of the courses as an assignment. This was in 1990.

          • I can't know for sure, but I think it's a matter of scope. How many levels of abstraction do you go through? How do you deal with generics? You might be able to do it with C, but when you've got C++/STL/Boost, there's just too much branching to do it real-time (I think...).

      Rumor has it MSFT is about to ditch .net developers in favor of HTML 5 + Javascript for "native" applications. Windows 8 allows you to run HTML 5 + Javascript "natively" (at least, as native as .net). The conferences MSFT has thrown lately have been light on .net love. So I expect the MS programmer base to grow, but not C++. C++ and likely always will but that place is shrinking.

    • I think you misunderstand what NaCl is. It is not some kind of C++ interpreter or VM; it does not "support C++ features". It runs native code. Said native code can be the output of a compiler of any language - there are some restrictions on what the output can look like (e.g. opcodes must be aligned), but there's no inherent restriction on languages. Today, Google supplies a C++ compiler (modded Clang? not sure what it is) that respects those constraints, but anyone can do so as well, including VC++.

        I guess in theory there's nothing stopping any compiler from outputting NaCl binaries, but at present none does, except for the aforementioned Google toolchain that comes with the NaCl SDK (which is a modded version of GCC). Code output for NaCl carries the extension ".nexe" -- technically it is native machine language, but the binary won't execute anywhere but inside NaCl. The SDK and its APIs are also changing a lot; .nexes compiled with earlier versions of the SDK won't work with Chrome 14 or later. [google.com]

        • I actually suspect it may be possible to write a translator that'd take a PE or ELF binary compiled with a normal compiler, and convert it to NaCl - replacing instructions and padding them as necessary.

      • " It is not some kind of C++ interpreter or VM"

        Actually, everything that's not kernel code "runs in a VM". Operating systens do memory address translation and bounds check (i.e. not violating other processes memory) during runtime.

      • No, I didn't misunderstand. I know it's not a tool. I just expect that once Google adapts a language on its platform, it will put some effort into producing some good tools.

        • Given their love for Eclipse in Android development department, I'd expect them to just ship it with Eclipse CDT.

          • I don't think so. I think they are preparing for a long-term separation from Java. And Eclipse is, of course, written in Java. Actually, I am mostly hoping that they are. I am just thinking that a company which managed accurate identification of web-wide unstructured text should have no problems producing a tool which would be superb at assisting in production of structured text like C++ code.
          • That's the first thing I thought as well. Eclipse is a good "delivery system" for their dev projects overall, I'm sure they have plenty of people already working on the general Eclipse project. But I think they might/should go further. Look at Aptana [aptana.com] -- it's specifically designed for web development. They could design Eclipse "variants" that are specific to Android-programming and, possibly, some version that facilitates programming NaCl modules.

    • Intellisense is by far the best C++ dev environment.

      I guess it's a matter of taste.
      I find that Visual Studio is very unintuitive and impractical for the way I code in C++.

        As I understand it, there are two formats. I remember the nexes being derived from ELF, but I can't find it now. There's also the Portable NaCl, which is some form of LLVM bytecode, so that it can be compiled on the client so as to natively support any architecture, without having to ship them C source.

    • "C/C++" is not meant to imply that the languages are almost the same, or anything like that. Rather, it's the recognition that these two are the most popular languages that are compiled directly to native code, by a very large margin. Another aspect of this is that many C++ programs use C libraries (SDL, zlib etc).

      I feel the same way about people who claim that since they know C and/or C++ they could learn Java in a snap. Yes, it's very likely that you will not have great difficulty picking up the Java syntax, since it's C-esque. That doesn't mean you'll be a "Java programmer" in 6 months.

    • that is so true. I know C99 and C++ (but I did use C++ since 2001) and they are quite different.

      And C++ only takes year to master if you try to know all the obscure corner case. If you don't abuse the template system as a turning complete language interpreted by the compiler, use operator overloading in a limited way, avoid reinterpret_cast, use variable scope for memory allocation and shared_ptr from boost when you really have to have a new, it is a fine language.
