The daemonizing code here is taken from an ActiveState recipe, which
includes changing to / as a general best practice. While that is
normally true to allow for deleting the directory that the daemon
process started in, in this case it is not relevant as this is not
intended to be an actual long-running daemon.
Issue ansible/ansible#17466
This provides support for passing additional positional parameters to async_wrapper.
Additional parameters will be used by the upcoming async support for Windows.
Because the async_status module will read from the same file that
the async_wrapper module is writing, it's possible that the file
may not be fully synced during a read, causing spurious failures.
Use a temp file to do an atomic operation on the file. We can't
use atomic_move() here as that doesn't work properly under async.
Also, let's not read concurrently from the same file the subprocess
is writing to. Instead, capture stdout/stderr via PIPE and write to
the file to avoid nasty races.
Prior to Python 2.5, SystemExit was a subclass of Exception.
In Py2.4, this is causing extra error output on valid sys.exit(0).
(Toshio) Call sys.exit from inside of the SystemExit exception handler so py2.4 and py2.5+ behaviour matches
* Fixing compile time errors irt a) exception handling for Python 3 in util, also: b) problem octal usage (fixed) and c) print json_dump -> print(json_dump(xyz) ... et al
* This code was not Python 2.4 compliant. Octal codes and exception handling is now working with Py 2.4, 2.6, & 3.5.
* Fixing formating (or rather reverting an non 2.4 compatible change). Works in compile & runtime checking.
* a) revert to use print sys.stderr not fail_json; b) fixed var name in exception
* Python 3 compatible print (print >>sys.stderr will generate a TypeError - now uses sys.stderr.write instead).
There are established connections for a service. The service is bound to a ipv4-mapped ipv6 address. Wait_for wrongly waits for clients listed in exclude_hosts.
Running async_status in an "until: result.finished" loop will mask a module failure (eg, traceback) with a
template failure, because the fail dict doesn't include "finished" (eg, you'll see "ERROR! The conditional check 'bogus_out.finished' failed. The error was: ERROR! error while evaluating conditional: bogus_out.finished ({% if bogus_out.finished %} True {% else %} False {% endif %}"). Because the failure dict still includes "failed: true",
this change has no effect on stoppage/failure reporting, it just prevents the common usage pattern from masking the underlying error message.
* reading from a socket that gave some data we weren't looking for and
then closed.
* read from a socket that stays open and never sends data.
* reading from a socket that sends data but not the data we're looking
for.
