2011-02-03HALFWORD ETS relative termsSverker Eriksson
In halfword emulator, make ETS use a variant of the internal term format that uses relative offsets instead of absolute pointers. This will allow storage in high memory (>4G). Preprocessor macros (like list_val_rel(TERM,BASE)) are used to make normal (fullword) emulator almost completely unchanged while still reusing most of the code.

2010-08-17Solaris/x86: Handle floating point exceptions properly in driver threadsBjörn Gustavsson
On Solaris/x86, the floating point exceptions bits seems to be propagated to child threads, so if scheduler threads use floating points exceptions, also driver threads will have floating points exception enabled. The problem is that erts_thread_init_float() has not been called for driver threads, and because of that matherr() will crash when called. Fix matherr() so that it will work even if erts_thread_init_float() has not been called. This fix was suggested by Mikael Pettersson.

elib_malloc is an alternate memory allocator that is no longer possible to build.
2010-08-17erts: Remove stray pre-ISO-C compatibility macrosBjörn Gustavsson
A long time ago, the Erlang run-time system could be build with pre-ANSI/ISO-C (K&R) C compilers, but that is no longer possible. Remove the remaining uses of the compatibility macros that made it possible that possible.

2010-08-10Rewrite ethread libraryRickard Green
Large parts of the ethread library have been rewritten. The ethread library is an Erlang runtime system internal, portable thread library used by the runtime system itself. Most notable improvement is a reader optimized rwlock implementation which dramatically improve the performance of read-lock/read-unlock operations on multi processor systems by avoiding ping-ponging of the rwlock cache lines. The reader optimized rwlock implementation is used by miscellaneous rwlocks in the runtime system that are known to be read-locked frequently, and can be enabled on ETS tables by passing the `{read_concurrency, true}' option upon table creation. See the documentation of `ets:new/2' for more information. The ethread library can now also use the libatomic_ops library for atomic memory accesses. This makes it possible for the Erlang runtime system to utilize optimized atomic operations on more platforms than before. Use the `--with-libatomic_ops=PATH' configure command line argument when specifying where the libatomic_ops installation is located. The libatomic_ops library can be downloaded from: http://www.hpl.hp.com/research/linux/atomic_ops/ The changed API of the ethread library has also caused modifications in the Erlang runtime system. Preparations for the to come "delayed deallocation" feature has also been done since it depends on the ethread library. Note: When building for x86, the ethread library will now use instructions that first appeared on the pentium 4 processor. If you want the runtime system to be compatible with older processors (back to 486) you need to pass the `--enable-ethread-pre-pentium4-compatibility' configure command line argument when configuring the system.

2010-06-10fix open_port with many unset env varsSverker Eriksson
The erlang:open_port spawn and spawn_executable directives can include an {env, Env} directive to set up environment variables for the spawned process. Variables can be unset with {"NameOfVariable",false}. A bug in ert/emulator/sys/unix/sys.c could cause unset variables to not be unset. This would typically happen if there where more variables to be unset than there where already set variables in the destination evironment. Fix this problem for unix and add a new regression test for it to the port test suite. Windows does not seem to have the same problem.

2010-05-03allow open_port to set env vars containing a trailing '=' characterSteve Vinoski
The erlang:open_port spawn and spawn_executable directives can include an {env, Env} directive to set up environment variables for the spawned process. A bug in ert/emulator/sys/unix/sys.c prevented applications from using {env, Env} to set an environment variable whose value ended with a '=' (equal sign) character; the code mistook the trailing equal sign as an indication that an environment variable was to be cleared from the environment of the spawned process. For example, passing an {env, Env} of {env, [{"foo", "bar="}]} would result in the code in sys.c seeing a string of the form "foo=bar=" The code would see the final '=' character and assume the directive wanted to clear a variable named "foo=bar" from the environment of the spawned process, rather than seeing it as a directive to set the environment variable "foo" to the value "bar=". Fix this problem and add a new regression test for it to the port test suite.
