coredump - Linux unable to create core dump from application -


i have 2 servers running vendor application. on 1 server if app crashes creates core dump second not.

the servers supposed set same trying figure out why application doesn't create core dump. i've checked typical settings , have been doing research no luck.

the strange part if run kill -s sigsegv $$ app user, generates core dump in same directory app supposed create core dump. vendor , linux group both unsure @ moment why i'm looking here help. 

$ cat /proc/sys/kernel/core_pattern core  $ cat /proc/sys/kernal/core_uses_pid 1  $ ulimit -c unlimited  $ cat /etc/security/limits.conf | grep core *   soft    core    unlimited *   hard    core    unlimited  $ cat /etc/profile | grep ulimit ulimit -c unlimited > /dev/null 2>&1  $ cat /proc/sys/fs/suid_dumpable 0  $ cat /etc/sysconfig/init | grep core daemon_corefile_limit='unlimited'

there several other reasons why coredump not created. check list of possible reasons in core(5): http://linux.die.net/man/5/core

check dmesg output.

check specific process corefile size limit in /proc/pid/limits.

check if process user can create file of typical coredump size in /proc/pid/cwd directory.

specify absolute file path in /proc/sys/kernel/core_pattern, pointing known writable location.

create short program adhering coredump-accepting protocol, saving somewhere, , specify in /proc/sys/kernel/core_pattern, according core(5). coredumps piped programs not subject limits.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
