* rickard/aux-work-bug/OTP-9567: Fix lost wakeup of scheduler when enqueuing auxiliary work
2011-09-22Fix lost wakeup of scheduler when enqueuing auxiliary workRickard Green
When auxiliary work was enqueued on a scheduler, the wakeup of the scheduler in order to handle this work could be lost. Wakeups in order to handle ordinary work were not effected by this bug. The bug only effected runtime systems with SMP support as follows: * Deallocation of some ETS data structures could be delayed. * On Linux systems not using the NPTL thread library (typically ancient systems with kernel versions prior to 2.6) and Windows systems, the {Port, {exit_status, Status}} message from a terminating port program could be delayed. That is, it only effected port programs which had been started by passing exit_status as an option to open_port/2.

* bjorn/erts/support-macosx-lion/OTP-9547: Fix build problems on MacOS 10.7 (Lion)
2011-09-20Fix build problems on MacOS 10.7 (Lion)Björn Gustavsson
On MacOS 10.7 (Lion) with Xcode 4.1 installed, the default C compiler is llvm-gcc-4.2. That compiler compiles beam_emu.c incorrectly, resulting in an emulator that will not start. The problem can be worked around by turning off all optimizations, but that will significantly degrade the performance of the run-time system. The problem can also be worked around manually like this: CC=gcc-4.2 ./configure To allow a working system to be built "out of the box", have the configure script set up the emulator Makefile so that gcc-4.2 will be used to compile beam_emu.c if the default compiler is llvm-based. All other C files will still be compiled with the default compiler.

The autoimport_SUITE:autoimport/1 test case would interpret data type definitions as function calls. Fix this by skipping to the <funcs> tag before starting to collect function names.

2011-09-03erlc_SUITE: Fix arg_overflow/1 test caseBjörn Gustavsson
In commit be8759e68b337524c056b8bb757ea68c9996d863, a buffer overflow was fixed in erlc and the erlc_SUITE:arg_overflow/1 test case was added. That test cases invokes erlc with 10000 -D options, which will result in 'erl' being invoked with more than 30000 arguments. On some platforms, the test case will fail for the wrong reason: * 64-bit Linux kernels before 2.6.23 limit the number of arguments in an excvp() call to 16383. (See "Number of arguments and maximum length of one argument" in http://www.in-ulm.de/~mascheck/various/argmax/.) * The command shell in Windows limits the size of the command line to 8191 characters. Depending on the platform, pass a different number of -D options to erlc. Since the size of the options does not matter for this test case, make the options as short as possible by generating numbers in base 36.
2011-09-02Update documentation and specifications of some of the zlib functionsHans Bolinder
The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2 accept iodata() as Dictionary. The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1, zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as data.
2011-09-02Fix enif_compare on 64bits machinesFilipe David Manana
In 64bits machines the Sint type has a size of 8 bytes, while on 32bits machines it has a 4 bytes size. enif_compare was ignoring this and therefore returning incorrect values when the result of the CMP function (which returns a Sint value) doesn't fit in 4 bytes. For example, passing the operands -1294536544000 and -1178704800000 to enif_compare would trigger the bug.

2011-08-25Add erlang:check_old_code/1Björn Gustavsson
Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-25check_process_code/2: Quickly return 'false' if there is no old codeBjörn Gustavsson
There is no need to suspend the process if the module has no old code. Measurements show that this change will make erlang:check_process_code/2 in an SMP emulator about four times faster if the module has no old code.

2011-08-15fix 64-bit issues in the garbage collectionRichard Carlsson
We discovered that if a single Erlang process tried to grow above 32 GB (i.e., more 64-bit words than can be counted by a 32-bit number), the VM failed to find the next larger heap size, even though there were plenty more heap sizes left to pick from and even though we had a lot more memory available on the machine. (Obviously, this is only applicable on 64-bit Erlang.) It turned out to be due to some 'int' variables in the heap resizing parts of erl_gc.c not being properly updated to 'Uint' or 'Sint'. Once that was fixed, I got segfaults instead as soon as the heap got larger than 2^32 words, due to even more 'int' declarations in the same file, but now in the GC code. After fixing this as well, I successfully ran an Erlang node in which a single Erlang process had a heap so large that I'm not at liberty to divulge the exact size, but I think the scientific term is "humongous", and I'm confident that there are no further immediate problems with very very large individual process heaps.
