* vinoski/ds2: further enhancements for dirty schedulers allow optional whitespace in dirty scheduler erl options
2014-02-24further enhancements for dirty schedulersSteve Vinoski
Add support for setting the number of dirty CPU schedulers online via erlang:system_flag/2. Assuming the emulator is built with dirty schedulers enabled, the number of dirty CPU schedulers online may not be less than 1, nor greater than the number of dirty CPU schedulers available, nor greater than the number of normal schedulers online. Dirty CPU scheduler threads that are taken offline via system_flag/2 are suspended. The number of dirty CPU schedulers online may be adjusted independently of the number of normal schedulers online, but if system_flag/2 is used to set the number of normal schedulers online to a value less than the current number of normal schedulers online, the number of dirty CPU schedulers online is decreased proportionally. Likewise, if the number of normal schedulers online is increased, the number of dirty CPU schedulers online is increased proportionally. For example, if 8 normal schedulers and 4 dirty CPU schedulers are online, and system_flag/2 is called to set the number of normal schedulers online to 4, the number of dirty CPU schedulers online is also decreased by half, to 2. Subsequently setting the number of normal schedulers online back to 8 also sets the number of dirty CPU schedulers online back to 4. Augment the system_flag/2 documentation in the erlang man page to explain this relationship between schedulers_online and dirty_cpu_schedulers_online. Also ensure that all dirty CPU and I/O schedulers are suspended when multi-scheduling is blocked via system_flag/2, and brought back online when multi-scheduling is unblocked. Add Rickard Green's rewritten check_enqueue_in_prio_queue() function that inspects process state more thoroughly to determine if to enqueue it and if so on what queue, including dirty queues when appropriate. Make sure dirty NIF jobs do not trigger erlang:system_monitor long_schedule messages. Add more dirty scheduler testing to the scheduler test suite. Remove the erts_no_dirty_cpu_schedulers_online global variable, since it's no longer needed. Execute dirty NIFs on a normal scheduler thread while multi-scheduling blocking is in effect. Evacuate any dirty jobs residing in the dirty run queues over to a normal run queue when multi-scheduling is blocked. Allow dirty schedulers to execute aux work. Set the dirty run queues halt_in_progress flag when halting the normal schedulers. Change dirty scheduler numbers to a structure including both scheduler number and type, either dirty CPU or dirty I/O. Add some assertions to ensure that dirty CPU schedulers operate only on dirty CPU scheduler process flags, and the same for dirty I/O schedulers.
2014-02-24Include more applications in upgrade_SUITESiri Hansen
Many appup files are now corrected and the applications can be included in the upgrade suite.
2014-02-24Start all non-core applications as temporary in upgrade_SUITESiri Hansen
2014-02-24Allow config to point out old releases in upgrade_SUITESiri Hansen
This suite was earlier only possible to run on linux hosts in the OTP test lab. Now a ct config file can be used to point out the two last major releases, e.g. like this: {otp_releases,[{r16,"/path/to/r16/bin/erl"}, {'17',"/path/to/17/bin/erl"}]}. Until OTP 17.0 is really released, the entry named '17' may well be left out, causing the test case upgrade_SUITE:minor to be skipped.
2014-02-24In upgrade_SUITE stop node with init:stop instead of test_server:stop_nodeSiri Hansen
This is only for nodes not started with test_server:start_node.

2014-02-24Use $INSTALL_SCRIPT instead of $INSTALL_DATA for start[_erl].srcSiri Hansen
To make the result executable as is the case for erl.src.
2014-02-24Add upgrade_SUITE to test upgrade of OTP releaseSiri Hansen
This test creates an OTP package of the previous major release and performs an upgrade to the current release.

2014-02-19beam/utils.c: Change back cmp() to only take two argumentsBjörn Gustavsson
Commit d5c238473b9cec819d93faaef4ccc00ddb60465f added a third argument to the cmp() function, but did not change the code generation of native code that called cmp(). Name the new functions with an "erts_" prefix, and reinstate the old cmp() function with two arguments. We don't have to keep a cmp() function in the halfword emulator, since HiPE does not support the halfword emulator.
2014-02-17allow optional whitespace in dirty scheduler erl optionsSteve Vinoski
The +SDcpu, +SDPcpu, and +SDio options did not properly handle having their arguments immediately following them without intervening whitespace, e.g. +SDio20 was treated as an error. Fix all the dirty scheduler command line options so they handle optional whitespace between them and their associated arguments.

2014-02-04gzio.c: Remove unnecessary usage of the OF() macroBjörn Gustavsson
Daniel Goertzen reported that commit 8a147a7365 broke building of Erlang/OTP on Gentoo Linux because the macro OF() was missing. Apparently, on Gentoo the OF() macro in zconf.h has been renamed to _Z_OF() (to avoid polluting the global namespace). Don't use the OF() macro in gzio.c since it no longer serves any useful purpose (it provided compatibility with pre-ANSI/ISO C compilers, but the rest of Erlang/OTP requires an ANSI/ISO C compiler anyway).
