The interface of this module is made to be as generic as possible
in order for other IPC mechanisms to mimic it and allow porting of
code between different os:es.

* lukas/erts/sendfile_passive_mode_fix/OTP-11614:
erts: fix bug when using passive mode and sendfile
|
|
The bug incorrectly issued driver_select when un-ignoring an fd
for a socket in passive mode, which caused an incorrect error
tuple to be returned when the remote end closed the connection.
|
|
This has been done because a slow client attack is possible if the
async thread pool is used. The scenario is:
Client does a request for a file and then slowly receives the file one
byte at a time. This will eventually fill the async thread pool with blocking
sendfile operations and thus starving the vm of all file operations.
If you still want to use the async threads pool for sendfile an option to
enable it has been introduced.

When the code_server is about to purge a module it will now issue
asynchronous check_process_code requests to all processes at once
instead of one at a time. These check_process_code operation can
execute in parallel.

The sync option adds the POSIX O_SYNC flag to the open system call on
platforms that support the flag or its equivalent, e.g.,
FILE_FLAG_WRITE_THROUGH on Windows. For platforms that don't support it,
file:open/2 returns {error, enotsup} if the sync option is passed in.
The semantics of O_SYNC are platform-specific. For example, not all
platforms guarantee that all file metadata are written to the disk along
with the file data when the flag is in effect. This issue is noted in the
documentation this commit adds for the sync option.
Add a test for the sync option. Note however that the underlying OS
semantics for O_SYNC can't be tested automatically in any practical way, so
the test assumes the OS does the right thing with the flag when
present. For manual verification, dtruss on OS X and strace on Linux were
both run against beam processes to watch calls to open(), and file:open/2
was called in Erlang shells to open files for writing, both with and
without the sync option. Both the dtruss output and the strace output
showed that the O_SYNC flag was present in the open() calls when sync was
specified and was clear when sync was not specified.

This function normalizes a path:
* convert atoms to strings
* flatten strings
* convert backslash to a forward slash
The bugfix is to only convert backslashes to forward slashes on
windows and not on any other platforms.

New BIF os:unsetenv/1 which deletes an environment variable and
returns 'true'.
Does not change any old functionality.
Calls the libc function unsetenv(3) on UNIX and
SetEnvironmentVariableW(key, NULL) on Windows. The unicode support
is the same as for os:getenv and os:putenv.
