2015-12-15erts: Never abort in the forked childLukas Larsson
We always want the error to propagate up to the application when a child cannot be created.
2015-12-15erts: Mend ASSERT makro for erl_child_setupSverker Eriksson
when called by hash.c for example. We use ASSERT from sys.h but erl_child_setup implements its own erl_assert_error() as it doesn't link with sys.o.
2015-12-15erts: Only use forker StackAck on freebsdLukas Larsson
2015-12-15erts: Add forker StartAck for port start flowcontrolLukas Larsson
An acknowledgement of the Start command has to be managed as we have to make sure that packages are not dropped and also that the close calls do not happen too early.
2015-12-15erts: Fix large open_port arg segfault for win32Lukas Larsson
os_SUITE:large_output_command send a 10k large argument to open_port({spawn,""}) which was too small for the 2K buffer allocated for win32. The buffer is now dynamic and any size can be used.
2015-12-15erts: Move os_pid to port hash to child setupLukas Larsson
Had to move the hashing because of a race that can otherwise happen where a new os_pid value was inserted into the hash before the previous value had been removed. Also replaced the protocol inbetween erts and child setup to be a binary protocol. This was done in order to deal with the varying size of Eterm.
2015-12-15erts: Handle all EINTR and EAGAIN cases in child setupLukas Larsson
2015-12-15erts: Make child_setup work with large environmentsLukas Larsson
2015-12-15erts: Fix uds socket handling for os xLukas Larsson
OS X is very strict in what it requires of you and also gives strange error codes for some errors. In this commit we remap EMSGSIZE to EMFILE and also precisely tune the amount of data we send on the socket so that we can recv only that data. If we try to recv more, recvmsg fails with EPIPE if the remote end has been closed.
2015-12-15erts: Fix dereferencing of unaligned integer for sparcLukas Larsson
2015-12-15erts: Flatten too long io vectors in uds writeLukas Larsson
2015-12-15erts: Create forker process for spawn driverLukas Larsson
Instead of forking from the beam process, we create a separate process in which all forks are done. This has several advantages: 1) performance: * don't have to close all fd's in the world * fork only has to copy stuff from a small process * work is done in a completely seperate process * a 3x performance increase has been measured, can be made even greater (10x) if we cache the environment in child setup 2) stability * the exec is done in another process than beam, which means that if the file that we exec to is on an nfs that is not available right now we will not block a scheduler until the nfs returns. 3) simplicity * don't have to deal with SIGCHLD in the erts Unfortunately, this solution also implies some badness. 1) There will always be a seperate process running together with beam on unix. This could be confusing and undesirable. 2) We have to transfer the entire environment to child_setup for each command. OTP-13088

This should be a harmless and compatible API change.
2015-10-15Fix erroneous use of __uint32_tIan Denhardt
The presence of this symbol is libc-specific. In particular, it is absent from musl. The correct solution is to use uint32_t.

2015-08-18Handle ERRNO_BLOCK in fd_driver async functionsSteve Vinoski
Several users on erlang-questions have reported problems with recent releases where output to standard_error causes standard_error_sup to die from receiving an unexpected eagain error. In the fd_driver, change the fd_async() function to handle EINTR, and change fd_ready_async() to handle ERRNO_BLOCK. Add a new test to standard_error_SUITE to generate output to standard_error and ensure that standard_error_sup does not die. Thanks to Kota Uenishi for contributing the test case.
2015-07-10ose: Remove all code related to the OSE portLukas Larsson
The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

2015-05-06erts: Increase buffer in erts_fp_check_init_errorMikael Pettersson
The current size is too small for 64-bit machines, causing messages to be truncated and making debugging more difficult.
