* PR6930: stapio: run in background as a daemonMasami Hiramatsu2009-03-203-4/+84
| | | | | | | Add '-D'(daemon mode) option to staprun/stapio for daemon mode. In this mode, stapio shows just its pid and detachs from console. Since it has no stdio, this mode requires -o option. stapio will exit when it receives SIGTERM or detects some error.
* PR6930: staprun: supports error message to syslogMasami Hiramatsu2009-03-203-8/+33
| | | | | Add an interface (eprintf) to output error messages to syslogd, because staprun has no stderr after detaching from console.

* PR9960: support tracepoint struct/union value argJosh Stone2009-03-191-3/+13
| | | | | | If a tracepoint arg is a structure or union that is passed by value, then this takes the address of the parameter so it can be used like a pointer in the rest of our code.

| * PR9959: hide tracepoint arguments of unknown typeJosh Stone2009-03-181-18/+22
| | | | | | | | | | | | We always have to know the type name of tracepoint arguments, so we can declare the right function callback, but we can suppress access to those types which we don't (yet) know how to read.
| * PR9959: improve tracepoint arg type-namingJosh Stone2009-03-181-14/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dwarf_type_name now works with more argument types. There were three cases that I needed to improve: - For "const struct foo*", the debuginfo has a const-DIE named "foo" chained to a struct-DIE named "foo", so we can't assume that seeing a name means we're down to the base type. The recursion now decends until it explicitly sees a base_type, typedef, struct, or union. - For "void*", the debuginfo has a pointer-DIE without any DW_AT_type after. Now I'm just catching that failed lookup and writing in "void". - For "va_list", the debuginfo actually resolves to an internal type "struct __va_list_tag*", but that struct has no declaration at the source level. I'm just hacking that exact case to say "va_list" instead, but it would be nice to find something cleaner... We'll probably still have problems if any tracepoint uses a function- pointer argument, but so far I've only seen that as a "void*", which we now handle ok.
| * Support tracepoints with no argumentsJosh Stone2009-03-181-0/+2
| | | | | | | | | | | | LTTng has a few tracepoints without any arguments, which caused our compile to fail, claiming that our entry function was not a declaration. This just adds an explicit (void) argument list for that case.

| * PR9951: Prevent GCC warnings in deref()Josh Stone2009-03-161-6/+5
| | | | | | | | | | | | | | | | | | In some configurations, GCC was warning about a possible use of _v in the deref macros. I could not reproduce the error, but the only case where _v is not written is if lookup_bad_addr rejects the address, in which case we will hit DEREF_FAULT and _v won't be used. Now we're priming _v=0 anyway, so GCC has no right to complain...
| * Fix regression in tracepoint unregistrationJosh Stone2009-03-161-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | Commit 96b030fe reorganized the tracepoint registration calls by creating generic wrappers that return int. However, the older tracepoint implementation (as found in RHEL5.3) returned void for unreg, so this was failing pass-4. Since we can't handle unregistration failures anyway, this change just makes the generic unregister function return void instead. As noted in the newly-added comment, it should be safe for us to ignore unreg failures.
