Hi David,
Thanks for looking at this!
Please review this updated webrev. The fix is the same but the
webrev contains a new test instead of modifying an existing test:
http://cr.openjdk.java.net/~hseigel/bug_8215398.2/webrev/
The logging implementation does not handle single quotes as
expected. For example, if the TestQuotedLogOutputs.java test is
changed to use single quotes instead of double quotes, it will fail,
even on Linux, because the single quotes are included as part of the
file name. They are not stripped off. That is why "java
-Xlog:safepoint=trace:'d:\safepointtrace.txt' -version" fails.
Perhaps a new bug is needed to change logging's handling of single
quotes? It's a bit surprising that this issue hasn't already been
reported.
Thanks, Harold

Hi,
Please review this small change to fix JDK-8215398. The fix works
by not treating ':' as a delimiter in a -Xlog... option string if
it is following by a '\' and preceded by either a single character
or the text 'file='. The fix is for Windows only.
Open Webrev:
http://cr.openjdk.java.net/~hseigel/bug_8215398/webrev/index.html
I think I can follow the fix.
But I'm a bit concerned about the test. AFAICS the test thought it
was already testing this case - albeit with the path quoted:
42 // Ensure log files can be specified with full path.
43 // On windows, this means that the file name will contain
44 // a colon ('C:\log.txt' for example), which is used to
45 // separate -Xlog: options
(-Xlog:tags:filename:decorators).
46 // Try to log to a file in our current directory, using
its absolute path.
47 String baseName = "test file.log";
48 Path filePath = Paths.get(baseName).toAbsolutePath();
49 String fileName = filePath.toString();
50 File file = filePath.toFile();
...
65 String[] validOutputs = new String[] {
66 quote + fileName + quote,
67 "file=" + quote + fileName + quote,
68 quote + fileName + quote + ":",
69 quote + fileName + quote + "::"
70 };
But even quoted if I specify the drive designator in the path, it
fails! Here's a local attempt at this:
D:\ade> apps\Java\jdk-11\fastdebug\bin\java
-Xlog:safepoint=trace:'d:\safepointtrace.txt' -version
[0.014s][error][logging] Invalid decorator '\safepointtrace.txt''.
Invalid -Xlog option
'-Xlog:safepoint=trace:'d:\safepointtrace.txt'', see error log for
details.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
So AFAICS the test can't possibly have been testing what it thought
it was testing! ???
I'm also not sure about just adding some unquoted variants to the
existing TestQuotedLogOutputs without renaming the test and updating
the @summary
Thanks,
David
JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8215398
The fix was regression tested by running Mach5 tiers 1 and 2 tests
and builds on Linux-x64, Windows, and Mac OS X, running tiers 3-5
tests on Linux-x64, running JCK-12 Lang and VM tests on Linux-x64,
and by hand on Windows.
Thanks, Harol
