So that if execute() is used within a forked process and if that process
is terminated prematurely, the log will show what the execute'd command
was doing
Always pass exactly one argument to sleep(1) since the BSD sleep (used
on OSX) does not sum its arguments like GNU sleep(1)
Perform more stringent checking on various timeout parameters to ensure
they are well-formed decimal floats
Remove the subshell parentheses around the command invoked using fork(),
so that the forked command inherits the file descriptors. This allows
it to be used like "fork some command < input".
When in a the finalise part of a test (possibly as a result of a
failure or error), make sure that shell backtraces do not list the
test case functions that failed, since they have already been
reported in a backtrace at the point of failure
Replace forkKillAll with fork_terminate_all
Replace forkWaitAll with fork_wait_all
Add fork_terminate and fork_wait functions
Introduce fork labels '%<alphanumeric>' as arguments to all fork
functions
Treat a forked process exit status 143 (killed with SIGTERM) as a
failure or error -- it happens when a forked process is terminated
using fork_terminate or fork_terminate_all
Add -h|--hexdump option to tfw_cat() and fix faulty logic in tfw_cat()
-v option wof files not ending in \n (newline)
Add TFWSTDOUT and TFWSTDERR env vars set by execute() with absolute
path names of files containing stdout and stderr respectively (as an
alternative to using replayStdout() and replayStderr()).
Default timeout is 60 seconds, can be overridden by --timeout=N on command-line
or by TFW_EXECUTE_TIMEOUT var or by --timeout option to execute() primitive
Cull timeout sleep processes created by wait_until() primitive
The 'includeTests' function failed if /bin/bash was not available or not
the same as the Bash used to run the top test script. This failed on
Solaris, where /usr/bin/bash is too old, and a privately-built Bash must
be used to run the test scripts.
New tfw_quieten() is similar to tfw_nolog(), but only silences the chatty log
output for asserts and other actions that succeed. Failures are still logged.
New tfw_multicolumn() encapsulates an awk(1) script to format a list into
columns that fit into $COLUMNS width.
Improve exit status handling for test ERROR and FAIL conditions.
The non-deterministic bug of "job %N terminated without result" is now fixed.
The cause was that Bash job numbers are allocated as max(current job numbers) +
1, so if the most recent job exited was not harvested before the next job was
started, then the job number would get re-used, deleting the un-harvested job's
result file.
SIGINT (ctrl-C interrupt) handling has been improved for the -j (parallel) and
non-parallel cases.
Test case execution in the non-parallel case is faster, by fixing a bug that
waited for a one-second timeout before starting each test job.
Now that tests can be included from other scripts, there is a possibility of
test name collision, so the main loop logic now uses the test sequence number
instead of the name internally to identify the test.
Support the --line option for assertGrep, assertStdoutGrep and assertStderrGrep
primitives to select a line or range of lines to which the grep will be
applied.
If supplied, the finally_TestCaseName() function, otherwise the finally()
function, is called after the test_TestCaseName() function terminates (with any
result). An assertion failure in the finally() function causes the test to
FAIL, but execution continues. So it is like teardown() but produces FAIL not
ERROR. Useful for clean-up that must be performed as part of the system under
test.
