Hello, It would be nice if we could get a full list of packages which have a wrong sha1 checksum. I don't have the bandwidth for a full mirror of all of Dag's rpms and i also don't have shell access to such a mirror. So a small request for a mirror admin: The following checks the files repodata/*.xml.gz against the sha1 sums in repomd.xml and checks the RPMS/*.rpm files against

Are there any standalone accurate garbage collectors that I could use in my project, rather than having to write me own (or use libgc, which is what I'm doing now)? Garbage collectors are subtle and very tricky and I really don't want to have to do one myself, as I know I'll just get it wrong. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ │ life←{ ↑1 ⍵∨.^3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵ } │ --- Conway's...

I'm having a curious issue with LLD/x86_64 linux/elf (Ubuntu 14.04); Where the l_addr of the link_map is invalid when linked with lld, but is fine with gnu ld. I'm using the libgc (boehm) code which when initializing reads the DYNAMIC/DEBUG link_map data, and crashes because the l_addr field has value out of readable memory. The strange this is that it happens only on some linux systems even though they're the same ubuntu version. My question is, what could possibly...

...'s native call mechanism to call the LLVM C bindings. I've got a couple of questions I'd be grateful if anyone can answer: My language in general and the compiler in particular rely heavily on Boehm GC. I'm assuming that LLVM is OK with being linked into a process that's using libgc? I really don't want to write a garbage collector! My existing IR has no structured type information. All structures are layed out exactly for the target machine before intermediate code is generated and array and intermediate code for class/struct field accesses are all pointer operations. I&...

...c unresponsiveness While suing mdb ( ::findleaks ) It says no memory allocation done and says no leaks found. 1) Is there any way where I can restrict dtrace to look for probe only certain source files or functions? 2) Is there any way to handle such problems? 3) I got a clue of using "libgc.so" which acts as garbage collector is there any problem in using and how reliable and effective is this. ( it works fine on sample application but not improvement in real application ) . I just linked the library "libgc.so" at compile time ? Anything else need to done for thi...

Hi, I'm running LLVM bitcode generated by my compiler under lli. The bitcode is linked against Boehm GC (lli -load=/usr/lib/libgc.so). It looks like Boehm GC isn't scanning global variables and as a result objects referenced only through globals are being prematurely collected. I understand that Boehm GC needs to see the data segment containing my global variables as a root. For native executables It's smart enough t...

.... At present the gcc-built code uses the setjmp/longjmp implementations provided by the gnu C library; and presumably the llvm-built code will use llvm's setjmp/longjmp intrinsics. Are the two implementations safely interoperable? Alternatives would be to force the llvm-built code to use the libgc setjmp/longjmp; force the gcc-built code to use a setjmp/longjmp borrowed from llvm; or perhaps make each setjmp tag the jmpbuf to show which flavor of longjmp is required.

As I understand it, LLVM simply gives you support for garbage collectors that you have to implement yourself and link into the final binary, similar to what C's malloc does (it's a library call). The issue with GC's is that they need to be provided info about the stack, thats where LLVM's support comes in. As far as I know, the garbage collector is linked into the final binary
