* paulgray/dtrace_snprintf_fix/OTP-11816: Fix DTrace/SystemTap-related formatting
2014-03-25Fix DTrace/SystemTap-related formattingScott Lystig Fritchie
Thanks to Michał Ptaszek for bringing this embarrassing formatting error to my attention. Many DTrace/SystemTap trace strings are incorrectly truncated at 4/8 bytes, depending on the CPU word size. This patch expands the work from commit d032e097 by zheng siyao.

2014-03-21zlib: Fix adler32_combine/4 and crc32_combine/4Björn Gustavsson
Since our config.h is included in each source file in the zlib directory, we must make sure that config.h is also included every time zlib functions are called to ensure that definitions of types are consistent. zlib_drv.c did not include config.h, which caused problems on a MacOS X Leopard system. What happened was that HAVE_UNISTD_H was not defined when zlib.h was included. When unistd.h is not known to exist, the type z_off_t will be set to a long (32 bits on this platform). But when the zlib source files were compiled, HAVE_UNISTD_H was defined, unistd.h would be included, and z_off_t would be set to off_t (64 bits; defined in unistd.h). As a result of the mismatch, calls to the adler32_combine() and crc32_combine() would pass only 32 bits in the len2 argument when 64 bits were expected.

2014-03-20Add test-case verifying runtime dependencies found by xrefRickard Green
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.

* bjorn/erts/fix-lingering-tracer: Teach the call_time trace to notice when the trace dies (non-SMP system)
2014-03-20Teach the call_time trace to notice when the trace dies (non-SMP system)Björn Gustavsson
The call_time trace is a special kind of tracing that requires a tracer process just like ordinary call trace, but it never actually sends anything to the tracer. It merely use the existence of a trace process (and call trace flags) as an indication that call_time tracing is active for the process. If the tracer dies in a non-SMP run-time system, processes with call_time tracing would not notice that the tracer had died. Furthermore, if the set_on_spawn flag was active, the dead tracer could be propagaged to newly spawned processes. Before accumulating trace information in a non-SMP system, always validate the tracer process. (In an SMP system, a reference to a dead tracer will be cleared away each time a process is scheduled.) While we could put all of the new code beam_bp.c, we have chosen to make a function call from beam_bp.c to a function in erl_trace.c for clarity's sake and to ease further maintenance. In the future, we might want to handle tracing in more similar ways in the SMP and non-SMP system.

2014-03-14erts: Change external format for mapsSverker Eriksson
to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn We think this will be better for future internal map structures like HAMT. Would be bad if we need to iterate twice over HAMT in term_to_binary, one for keys and one for values.

2014-03-12Pass full strings to DTrace probesMichal Ptaszek
Whenever string is passed as an argument to a DTrace probe, its length should be properly computed. Until now in order to get length of the input buffer size_of(char *) was used - which evalutes to 4 or 8 (depending on the architecture). To get a proper length, size_of(DTRACE_CHARBUF_NAME(buffer_name)) should be used.
