Hi, The background is that I have an automated build/test system, but when a test fails, all that is saved is the test stdout/stderr, the build tree is destroyed regardless of the results.
When debugging test failures on systems that use dejagnu for tests, it is often useful to have the expect logs available to figure out what was the "spawn" output and why the "expect_pass" regexp did not match it. Usually, that information gets saved in the *.log files but is not usually printed to stdout (which can be done by using the "log_user 1" expect command.) While the *.log files are useful to troubleshoot the issue, to use them I need to have the build/test tree around. While I can include commands in my test script to look for *.log files (but all of them? no, I just want the runtest ones) and then use a glob, cat the files, etc. But then do I still keep the original test output? If I do, I get duplicated sessions, if I don't, I might be losing some information that is only printed there... So, being able to include the log_user output with the runtest stdout would be very interesting. There is, actually, a way to include the log_user output in stdout, and that is to increate verbosity to at least 3, since there is already a check for $verbose > 2 that does log_user 1. The main problem with that approach is that I find increasing verbosity is actually useful to debug *runtest* itself, while log_user output is useful to troubleshoot the tests being run by runtest. (Assuming I'm using a stable version of "runtest", I don't think I'll need to debug it that often, while I find myself debugging tests quite often.) So, I'm proposing adding a new option (--log_user is my suggestion, but feel free to pick something else) to allow enabling "log_user" expect output to stdout without the need to increase verbosity. Let me know if you have any comments about the patch.
