2015-12-15erts: Only use forker StackAck on freebsdLukas Larsson
2015-12-15erts: It is not possible to exit the forker driverLukas 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: Fix memory leak at async open portLukas Larsson
When an async open port fails early, it would sometimes leak memory.
2015-12-15kernel: Remove cmd server for unix os:cmdLukas Larsson
Since we no longer to vfork in the emulator there is no need to serialize the os:cmd calls through a central command server. This greatly decreases the complexity of this code and should make it fast+more scalable. OTP-13089
2015-12-15erts: Add testcase for huge port environmentLukas Larsson
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 forker driver ifdefs for win32Lukas 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: Add fd count test for spawn_driverLukas 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
2015-12-15erts: Move sys drivers to another fileLukas Larsson
2015-12-15erts: Change name of child_setup to erl_child_setupLukas Larsson
2015-12-15erts: Rename sys driver structsLukas Larsson
2015-12-15erts: Refactor out erts functions from hashLukas Larsson
2015-12-15erts: Bump driver minor versionLukas Larsson
2015-12-15erts: Add erl_drv_set_pidLukas Larsson
