Review Request: openbsd-malloc - Alternative malloc() implementation
Last modified: 2008-06-22 13:14:38 EDT
Spec URL: http://lemenkov.googlepages.com/openbsd-malloc.spec SRPM URL: http://lemenkov.googlepages.com/openbsd-malloc-0-1.src.rpm Description: This package contains experimental alternative to glibc implementation of malloc() which is prone to heap fragmentation due to use of deprecated brk() syscall; one might find it useful to reduce e.g. Firefox memory consumption (though reportedly won't work with e.g. Emacs). Use openbsd-malloc some-program to run some-program this way.
Please ensure that your build honors the RPM build flags by adding %{optflags} (or $RPM_OPT_FLAGS) to the gcc invocation: %build gcc -shared -fPIC %{optflags} %{SOURCE0} -o malloc.so

Some remarks: 1. MUSTFIX: This spec doesn't apply $RPM_BUILD_ROOT. It compiles and places its files directly into */BUILD. One way to approach this: %setup -c -T 2. Is there an agreement with the glibc developers upon using the name libmalloc.*? To me, this name appears as too general. 3. http://mr.himki.net/index-alloc.html is in a Cyrillan written language (Russian?). An English version would be helpful, because except of the source code there doesn't seem to be any other documentation. 4. The source file seems to be intended to be used as a preloaded module: From the source code: * Compilation: gcc -shared -fPIC -O2 OpenBSD_malloc_Linux.c -o malloc.so * Launching: LD_PRELOAD=/path/to/malloc.so firefox I am not sure if packaging it as a library is a wise decision.

Are any recomendations about handling of preloaded libraries? http://lemenkov.googlepages.com/openbsd-malloc.spec http://lemenkov.googlepages.com/openbsd-malloc-0-4.src.rpm
Note that this built for me in mock on rawhide but did not install: mock: /usr/bin/yum --installroot /mock/fedora-development-x86_64/root/ install /mock/fedora-development-x86_64/result/openbsd-malloc-0-4.fc9.x86_64.rpm /mock/fedora-development-x86_64/result/openbsd-malloc-debuginfo-0-4.fc9.x86_64.rpm Error: Missing Dependency: ld-linux-x86-64.so.2(GLIBC_PRIVATE)(64bit) is needed by package openbsd-malloc
I'm no longer interested in packaging this.
