make: *** [SunOS-sunw-sparc] Error 3

At commit 7e8647e, "make macos" fails with numerous errors. Some are in Heap-Layers, some not. Transcript below. You may well be aware of all this :)

I downloaded the 3.9 tarball and it built (with many warnings). It would be nice if there were Git tags for the releases, assuming you have the history in Git.

Thanks!

When you add a uselibhoard.cpp file at your project on windows x64 platform, it occurs link error.
because of _WIN32 define.
_WIN32 define in uselibhoard.cpp has to be removed.

3.12 is just failing when LD_PRELOADed on Ubuntu Linux 16.04 LTS — on literally any executables' run.

Is Hoard alive at all? I understand that tcmalloc outperforms it a bit (and is under active development for sure) but it'd be great to know the status for sure as well.

make: *** [linux-gcc-x86-64] Error 1

Tried compiling commit 5996bcf (current master) for Windows (VC2008) and it failed on hoardsuperblockheader.h line 287 with an error about it not being legal to use "this" there.

Fix is to assign sizeof(*this) to a local const size_t variable; this can then be used in the sassert template without errors.

Looks like Hoard's Makefile and GNUmakefile clone master of Heap-Layers. Unless you never change Heap-Layers, it seems likely that at some point you will introduce a change to Heap-Layers that will require a corresponding change to Hoard. When that happens, old versions of Hoard (which might be present in package management systems) will no longer be able to build. This problem might not always be noticed right away, leaving your software in broken state in that package management system for an unbounded period of time.

For this reason, you should download a specific version of Heap-Layers that is known to work with this version of Hoard.

I think git already behaved that way before when you were using submodules, so you could get this behavior back by reverting 5275686 and also making the same change to GNUmakefile.

Program: Executable / with /MD flag / x64 / Release / VC10
Code: Compiled from source / x64 / Release. / VC10

In the binary project I've updated the linker options to link to the appropriate usewinhoard.obj and winhoard.lib. I've placed the winhoard.dll next to the executable. I've validated that it is required during runtime.
The runtime on my program is not improving and I know that there is alot of room for improvement as I have verified this using other allocators. The dll does get hooked, I have checked this by std::cout-ing some indicators.
Do I need to explicitly call hoard_malloc? As I read it Hoard should hijack any new, malloc calls. If that is the case how does it work in the presence of another pair of allocation hooks (this is what my code has at the moment). Do I need to take those out for hoard's hooks to kick in?

Thanks.

I tried to build libhoard on windows with VS2015 using nmake. It built successfully. But when I try to run a sample program using hoard, It crashes in the following call stack :

It's a simple program to allocate memory :

int main()
{
    char *str = NULL;
    int rc = ERROR;

    printf("Allocating a buffer...\n");
    str = (char*)malloc(MAX_BUF_SIZE*sizeof(char));

    if (str == NULL)
    {
        printf("Allocation of buffer failed !!! Exiting... \n");
        return ERROR;
    }

    strncpy(str, "Hello", 6);
    printf("Entered string is : %s\n", str);
    return OK;
}

It's a visual studio project where I added source/uselibhoard.cpp as additional source file and libhoard.lib in the linker options. Please check the attached screenshots.

Not very sure where to go with this. Any help would be appreciated.
Another question while I'm at it how effective is hoard with games?

GNUmakefile hardcodes the architectures for which to compile on macOS in the MACOS_COMPILE and MACOS_COMPILE_DEBUG variables. You should make this configurable via another makefile variable. Currently you're hardcoding the architectures i386 and x86_64, but Apple is phasing out 32-bit support and you can't compile for i386 anymore as of the macOS 10.14 SDK.

I could not compile hoard from source in fedora 17 x64 ( #5 I compiled it with compat gcc 34 and produced libhoard.so. After that tried to compile and test cache-scratch with and without hoard.so the result was weird as below.could you tell me where is the problem?.I also download libhoard.so for 64bit llinux from <a href=http://plasma.cs.umass.edu/emery/index.php?page=download-hoard>Emery but the result was the same.

g++ /home/src/Hoard/benchmarks/cache-scratch/cache-scratch.cpp -I../common/ /home/javad/src/Hoard/libhoard.so -o cache-scratch-hoard -lpthread

./cache-scratch 1 1000 1 1000000
Time elapsed = 2.383032 seconds.
./cache-scratch-hoard 1 1000 1 1000000
Time elapsed = 10.085448 seconds.

Hi,

I'd like to be able to add additional fields to the HoardSuperblock header. If the Header were passed as a template parameter, that would be easy.

Thanks,
Irene

Hello,

It's possible that this is a quirk or unrealism of the particular benchmark design rather than a failing in hoard as such, but I tried running it through the t-test1.c test case from the ptmalloc family and the results were not good. (Tests run on Windows 7 high-end quad-core machine; each size change was run as a separate process.)

It performed reasonably well (better than the OS allocator and a ptmalloc-derivative allocator) with allocation sizes up to 8192, but when using size parameters of 16384 and above it performed abysmally. (eg. 0.3s at 8192 size, 22s at 16384 size; note that the system allocator scored 1.1s for hoard's 22s, and this difference only got worse as the size increased.)

There was also significantly higher CPU usage (to the point of pegging all processors to 100%, making the system unusable) when running those particular test values.

Hello

I am trying to use scalene on some code.

I cannot post the whole code, but here is what it does, at least:

• creating threads, processes, using the 'forkserver' start method, on linux, and multiprocessing.get_context()
• overriding threading.Thread.run
• creating multiprocessing,queues

I tried to create a simple reproducer code, but I couldn't find what causes the error.

When my code creates new processes, I get these errors:

Exception ignored in: <function _after_fork at 0x559984ec9880>
Traceback (most recent call last):

Is there a way to get more details about this exception?

Thank you

Hoard crashes when SUPERBLOCK_SIZE is #define'd with values larger than 256M.

We think it's during program initialization. Here's the backtrace:

Thanks in advance!

You currently install your library with e.g.

cp libhoard.dylib $(PREFIX)

This assumes $(PREFIX) is writable. It might not be in the context of a package management system that wants to stage the files in a temporary location first.

You should support the standard $(DESTDIR) variable for this, by changing these copy commands to e.g.

cp libhoard.dylib $(DESTDIR)$(PREFIX)

Please update the documentation with the correct build target "linux-gcc-x86_64"

I did the following, not sure why but this seems to break everything on Ubuntu 18.04

git clone https://github.com/emeryberger/Hoard
make
echo "export LD_PRELOAD=$PWD/libhoard.so" >> ~/.bashrc

Opening up a new terminal and trying to do anything like ls, vim, chmod, etc. causes a seg fault

This is the same as #49 but I could not re-open that issue

I'm evaluating the possibility to replace malloc() for LLVM.
I hit some problems I'd like to point out here:
The README is wrong:

The malloc() replacement example doesn't quite work, in basic cases:

$ cat patatino.cpp
#include <stdlib.h>

int main (void) {
        malloc(16);
        return (0);
}

If I try to run the way it's described on the website:

c:\Users\fluttershy\work\Hoard\src>cl /Ox /MD patatino.cpp source\libhoard.cpp libhoard.lib

It seems the issue is that it's not able to locate the headers, something like this might fix:

But immediately after I hit another problem:

c:\users\fluttershy\work\hoard\src\heap-layers\heaps\combining\hybridheap.h(32):
 fatal error C1083: Cannot open include file: 'heaplayers.h': No such file or di

Any ideas on how to fix? I think the instructions on the website need some love.

Please remove the -g flag in the GNUMakefile for non debug builds. Could see a performance improvement without that. (also looks like a typo in section LINUX_GCC_x86_64_COMPILE ).

I clone Horad by usage the link:

https://github.com/emeryberger/Hoard.git

Then as descibed in documentation I change directory to

C:\hoard\src

Then I try to build it:

C:\hoard\src> nmake

And receive error:

git clone https://github.com/emeryberger/Heap-Layers
fatal: destination path 'Heap-Layers' already exists and is not an empty directory.

Its bug - the Heap-Layers already exist when I clone Hoard repo. Ok, I delete Heap-Layers folder and try to build again:

C:\hoard\src> nmake

And receive followed error:

source\libhoard.cpp(34): fatal error C1083: stdalign.h: No such file or directory

So at now the sources can not be compiled on the Windows platform. Could you fix it?

Your library is being built without the install_name being set, which means that it cannot be used unless the user manually fixes the install_name later using install_name_tool.

You have instructions about setting DYLD_INSERT_LIBRARIES to the path where the library is, which would be unnecessary if you set the install_name to the place where the library will be installed.

You could do this by adding -install_name $(PREFIX)/libhoard.dylib to MACOS_COMPILE and MACOS_COMPILE_DEBUG in GNUmakefile.

Am using Hoard in my application to run on both Linux and Windows. While it runs perfectly fine on Linux on Windows after some allocations it crashes at a std::make_shared for an object. Its gets a "Exception thrown at 0x00007FF6E568FCDE in : Access violation writing location 0x00007FF6E5778078". Does it require any specific configuration for Windows? I have followed the exact instructions to link to libhoard.dll and also my application loads it too but after some random number of allocations it crashes the application. The application works fine without Hoard. Am using Visual Studio 2015 community version on Windows 10 host.

when i compile this program, type "make" instruction, so i change "-std=c++14" to "-std=c++11".
then i export envorment instr,
OK. when i run the program, find the performance decline ? So How to solve this problem?

I don't really find it any useful or even common for allocators to report they're being put in use, what's the logical reasoning behind it?

Would you like to add more error handling for return values from functions like the following?

• dlsym ⇒ thr_create
• LoadLibrary ⇒ ReferenceHoard

Is this intentional?

I am in the process of reviewing this library for use in a multi-threaded utility that makes extensive use of the STL. When I attempt to compile the source using Visual Studio 2010 I get the following error from the command line:

I would like to directly compile the library into the program to eliminate the need to distribute another file if necessary, but I cannot even built the library as retrieved from the source. What am I missing? Thanks.

Hello,

I am using your allocator in a memory intensive application. If the application allocates and deallocates many small objects, then not enough free space for a big memory block remains. It seems that the allocator doesn't free any unused page, but this should be part of the task of your blowup prevention.

Test system:
Windows 7 x64
Visual Studio 2005
32bit application
Hoard 3.8

test application:

#include "hoard-38/src/libhoard.cpp"

class CNode
{
public:
    double dummy;
    CNode *next;

    CNode(double v)
    {
        this->dummy = v;
        this->next = NULL;
    }
};

int main()
{
    // Init TLS, ...
    DllMain(NULL, DLL_PROCESS_ATTACH, NULL);

    int bigSize = 600000000;
    char *big;

    printf("allocate big memory block, use it, free it ... should be okay\n");
    big = new char[bigSize];
    memset(big, 0, bigSize);
    delete[] big;
    big = NULL;

    printf("allocate many small objects ... should be okay\n");
    // memory usage of the process increases
    int smallElementCount = 100000000;
    CNode head(0), *current;
    current = &head;

    for (int i = 1; i < smallElementCount; i++)
    {
        current->next = new CNode(i);
        current = current->next;
    }

    printf("free all small objects ... should be okay\n");
    // memory usage of the process does NOT decrease
    current = head.next;
    while(current)
    {
        CNode* t = current->next;
        delete current;
        current = t;
    }

    printf("allocate another big memory block, use it, free it ... should be CRASH (bad_alloc)!!!\n"); 
    big = new char[bigSize];
    memset(big, 0, bigSize);
    delete[] big;
    big = NULL;

    return 0;
}

Can you check this issue, please. This would be helpful.

Thanks
Bastian

when i cross compilt it, it is error:

Hi @bertwesarg , thanks for the great work. Is it possible to provide a single-header version of Hoard?

The leader comment of benchmarks/shbench/shbench.cpp says:

 * This source code, or source code derived from it, may not be redistributed
 * without express written permission of the copyright owner.

Could you clarify whether we (interested devs on GitHub) have such permission? I don't mean here in this issue discussion so much as in the file itself.

This license declaration seems at odds with "Hoard is distributed under the GPL".

Thanks!

Hi,

I have compiled Hoard according to the instructions under Windows 10 with Compiler "Microsoft (R) C/C++ Optimizing Compiler Version 19.00.24218.1 for x64".

I have then created a new dir containing

• hello.cpp
• make.bat
• libhoard.lib
• libhoard.dll
• uselibhoard.cpp

I am attaching the text files as "hg_test.zip" to this post:
hg_test.zip

I have then called "make" which creates "hello.exe", with this output on the console:
``

hello.cpp

/out:hello.exe
hello.obj
uselibhoard.obj

``

(OK - I have specified /EHsc in addition to get rid of those warnings, but this is irrelevant here as the crash still happens then.)

When I now execute "hello.exe", a popup window appears: "Appication Error - The application was unable to start correctly (0xc0000142). Click OK to close the application."

What am I doing wrong?

Best regards,
Hagen

I wanted to evaluate the Hoard for one of the project but i observed that Hoard fails to allocate more than 2GB of memory. I built the Hoard 3.12 with g++ version 4.9.0 on Linux. Is there any limitation with the Hoard for the memory allocation. If not what could be wrong?
The allocation for 2147483647 bytes succeeds and allocation for 2147483648 onward fails.

Below are the g++ and Linux details:

I tried master (Hoard May 24 2018, Heap-Layers Oct 17 2018) and it builds, but I would rather not update the MacPorts port to some random point in time of your repositories. Is a new stable release planned at some point to which I could then update the port?

Would be great if, when you make a new release, you could provide a tarball containing the complete source code of Hoard and Heap-Layers and attach it to the GitHub release, like you did before for version 3.10, so we don't have to clone from git.

Updated the Makefile to use CPPFLAGS; verify that this does the right thing on Linux builds. If not, modify to include appropriate optimizations.

It remains to be seen whether this is a problem in practice but it would be good to continue to maintain 32-bit support if possible.

Try to get working for FreeBSD for version 4 release.

I tried to build hoard from source on linux Fedora core 17 (64bit) gcc version 4.7.2 20120921 (Red Hat 4.7.2-2) (GCC) I did git clone --recursive but it give out below error. here is some part of compilation output which contained errors.

Thanks

Hi Emery,

In your Hoard paper, should the condition of line 9 in free pseudocode be or instead of and?

I downloaded the latest code from github and ran nmake from a VS 2017 command line. I got the following error:

#54 seems to be breaking the Windows build as MSVC won't understand always_inline or gnuwrapper code.

The problematic malloc at my side leads to the allocation of 314956304 bytes. Malloc of smaler arrays went fine.

How may I use Hoard for large memory allocs?

it works in CentOS with some error,how to solve this problem...thanks
