2012-01-13Avoid creating an undefined start_phases entry when generating a releaseJuan Jose Comellas
When a release is generated and the applications in the release do not define a value for the start_phases entry of their .app files, reltool will generate the following entry in the .app files of the release: {start_phases, undefined} If this happens, when trying to create a release upgrade systools will fail because it doesn't allow the start_phases entry to be set to undefined. This patch avoids this situation by not generating a start_phases entry when it is set to undefined.

* bjorn/compiler/match-fail/OTP-9842: Add the beam_except pass to optimize exceptions Eliminate the match_fail primop in v3_kernel and later passes
2012-01-04Add the beam_except pass to optimize exceptionsBjörn Gustavsson
In order to save space, rewrite suitable calls to erlang:error/{1,2} to special BEAM instructions. This code is probably longer than the code taken out of v3_life and v3_codegen in the previous commit, but it is much easier to understand and maintain since the BEAM assembler format is better understood than the v3_life format.
2012-01-04Eliminate the match_fail primop in v3_kernel and later passesBjörn Gustavsson
In the v3_life pass, it is assumed that a 'match_fail' primop only occur at the top-level and at the end of a function. But this code: do_split_cases(A) -> case A of x -> Z = dummy1; _ -> Z = dummy2, a=b end, Z. will be optimized by sys_core_fold to the following code: 'split_cases'/1 = fun (_cor0) -> let <_cor7,Z> = case _cor0 of <'x'> when 'true' -> < 'dummy1','dummy1' > <_cor6> when 'true' -> %% Here follows a 'match_fail' primop inside %% multiple return values: < primop 'match_fail'({'badmatch','b'}),'dummy2' > end in Z moving the 'match_fail' primop into a "values" construction. In the future, we would like to get rid of the v3_life pass (it is there for historical reasons), so in the mean-time we prefer to not add more code to it by generalizing the handling of 'match_fail'. Since the 'match_fail' primop can be simulated by erlang:error/{1,2}, the simplest solution is to translate 'match_fail' to a call to erlang:error/{1,2} in v3_kernel and remove the handling of 'match_fail' in v3_life and v3_codegen. It is tempting to get rid of 'match_fail' also in the Core Erlang format, but there are two issues: - Removing the support for 'match_fail' completely may break tools that generate Core Erlang code. We should not do that in a minor release. - There is no easy way to generate a 'function_clause' exception that will remain correct if it will be inlined into another function. (Calling "erlang:error(function_clause, Args)" is fine only if it is not inlined into another function.) A good solution probably involves introducing new instructions, which is better done in a major release. Noticed-by: Håkan Matsson Minimized-test-case-by: Erik Søe Sørensen

A feature test for the lwsync instruction performed on PowerPC hardware at runtime system startup got into an eternal loop if the instruction was not supported. This bug was introduced in erts-5.9/OTP-R15B.
2011-12-27Include wakeup pipe in /dev/poll poll-set also on non-SMPRickard Green
I/O events could potentially be delayed for ever when enabling kernel-poll on a non-SMP runtime system executing on Solaris. When also combined with async-threads the runtime system hung before completing the boot phase. This bug was introduced in erts-5.9/OTP-R15B.

2011-12-20Check that sys.config and relup have valid content when added to tarSiri Hansen
systools:make_tar now does a minor check of the content of sys.config and relup before adding them to the tar file. If the content is not readable or in expected format, the function fails.
2011-12-20Reject systools:make_script if kernel and stdlib are not permanent in .relSiri Hansen
It should not be possible to create a .boot file unless kernel and stdlib are stated as permanent applications in the .rel file. Note that 'permanent' is the default start type, so not specifying a start type for kernel and stdlib is, as always, ok.

Supervisor should never keep child specs for dead temporary children.

It is possible also in non-SMP case: 1. The process receives an exit signal and is set in status exiting and inserted into the run queue. 2. The distribution port exits before the process has been selected for execution and cannot remove the link half on the process since it is in status exiting. 3. Process is selected for execution and when removing this link half the distribution channel is gone!
