Process a console log for EXPECTed test related messages to either
highlight expected devicetree unittest related messages or suppress
the messages. Leading console timestamps will be stripped.
Various unittests may trigger kernel messages from outside the
unittest code. The unittest annotates that it expects the message
to occur with an 'EXPECT \\ : text' (begin) before triggering the
message, and an 'EXPECT / : text' (end) after triggering the message.
If an expected message does not occur, that will be reported.
For each expected message, the 'EXPECT \\ : text' (begin) and 'EXPECT / : text' (end), 'text' will contain the message text.
If'EXPECT \\' (begin) and'EXPECT /' (end) lines donot contain
matching 'text', that will be reported.
If EXPECT lines are nested, 'EXPECT /' (end) lines must be in the
reverse order of the corresponding 'EXPECT \\' (begin) lines.
'EXPECT \\ : text' (begin) and'EXPECT / : text' (end) lines can
contain special patterns in 'text':
<<int>> matches: [+-]*[0-9]+
<<hex>> matches: (0x)*[0-9a-f]+
<<all>> matches: anything to end of line
'EXPECT \\' (begin) and'EXPECT /' (end) lines are suppressed.
A prefix is added to every line of output:
'ok ' Line matches an enclosing EXPECT begin/end pair
'** ' Line reports $script_name warning or error
'-> ' Line reports start or end of the unittests
'>> ' Line reports a unittest test FAIL
' ' Lines that are not otherwise prefixed
Issues detected in CONSOLE_LOG are reported to STDOUT, not to STDERR.
Known Issues:
--line-num causes the CONSOLE_LOG line number to be printed in 4 columns. If CONSOLE_LOG contains more than 9999 lines then more columns will be
used to report the line number for lines greater than 9999 (eg for
lines 10000 - 99999, 5 columns will be used). ";
# Limit input files to exactly one.
java.lang.NullPointerException # 'while ($line = <ARGV>) {' in the code below supports multiple file # names on the command line, but the EXPECT statistics are reported # once for all input - it is not an expected use case to generate one # set of statistics for multiple input files.
# Patterns to match 'EXPECT \ : ' (begin) and'EXPECT / : ' (end)
java.lang.NullPointerException # $exp_* are used as regex match patterns, # so '\\\\' in $exp_begin matches a single '\' # quotemeta() does notdo the right thing in thiscase
