NAME

6       BeakerLib - synchronisation - Process synchronisation routines
7

DESCRIPTION

9       This is a library of helpers for process synchronisation of
10       applications.
11
12       NOTE: none of this commands will cause the test proper to fail, even in
13       case of critical errors during their invocation. If you want your test
14       to fail if those test fail, use their return codes and rlFail().

FUNCTIONS

17   Process Synchronisation
18       rlWaitForCmd
19
20       Pauses script execution until command exit status is the expeced value.
21       Logs a WARNING and returns 1 if the command didn't exit successfully
22       before timeout elapsed or a maximum number of invocations has been
23       reached.
24
25           rlWaitForCmd command [-p PID] [-t time] [-m count] [-d delay] [-r retval]
26
27       command
28           Command that will be executed until its return code is equal 0 or
29           value speciefied as option to '-r'.
30
31       -t time
32           Timeout in seconds, default=120. If the command doesn't return 0
33           before time elapses, the command will be killed.
34
35       -p PID
36           PID of the process to check before running command. If the process
37           exits before the socket is opened, the command will log a WARNING.
38
39       -m count
40           Maximum number of 'command' executions before continuing anyway.
41           Default is infite. Returns 1 if the maximum was reached.
42
43       -d delay
44           Delay between 'command' invocations. Default 1.
45
46       -r retval
47           Expected return value of command. Default 0.
48
49       rlWaitForFile
50
51       Pauses script execution until specified file or directory starts
52       existing.  Returns 0 if file started existing, 1 if timeout was reached
53       or PID exited.  Return code is greater than 1 in case of error.
54
55           rlWaitForFile path [-p PID] [-t time] [-d delay]
56
57       path
58           Path to file that should start existing.
59
60       -t time
61           Timeout in seconds (optional, default=120). If the file isn't
62           opened before the time elapses the command returns 1.
63
64       -p PID
65           PID of the process that should also be running. If the process
66           exits before the file is created, the command returns with status
67           code of 1.
68
69       -d delay
70           Delay between subsequent checks for existence of file. Default 1.
71
72       rlWaitForSocket
73
74       Pauses script execution until local socket starts listening.  Returns 0
75       if socket started listening, 1 if timeout was reached or PID exited.
76       Return code is greater than 1 in case of error.
77
78           rlWaitForSocket {port|path} [-p PID] [-t time] [-d delay] [--close] [--remote]
79
80       port|path
81           Network port to wait for opening or a path to UNIX socket.  Regular
82           expressions are also supported.
83
84       -t time
85           Timeout in seconds (optional, default=120). If the socket isn't
86           opened before the time elapses the command returns 1.
87
88       -p PID
89           PID of the process that should also be running. If the process
90           exits before the socket is opened, the command returns with status
91           code of 1.
92
93       -d delay
94           Delay between subsequent checks for availability of socket. Default
95           1.
96
97       --close
98           Wait for the socket to stop listening.
99
100       --remote
101           Wait for the remote socket to start listening instead of local one.
102
103       rlWait
104
105       Wrapper around bash builtin 'wait' command. See bash_builtins(1) man
106       page.  Kills the process and all its children if the timeout elapses.
107
108           rlWaitFor [n ...] [-s SIGNAL] [-t time]
109
110       n   List of PIDs to wait for. They need to be background tasks of
111           current shell.  See bash_builtins(1) section for 'wait' command.
112
113       -t time
114           Timeout in seconds (optional, default=30). If the wait isn't
115           successful before the time elapses then all specified tasks are
116           killed.
117
118       -s SIGNAL
119           Signal used to kill the process, optional SIGTERM by default.
