Sporadic issues are difficult to analyze on the buildbots because sometimes a test fails, but when it runs again in verbose mode... it doesn't fail anymore. Typical example:
===============================
[ 99/356/1] test_smtplib
Re-running test test_smtplib in verbose mode
(...)
testTimeoutValue (test.test_smtplib.GeneralTests) ... ok
testBasic (test.test_smtplib.DebuggingServerTests) ... test test_smtplib failed -- multiple errors occurred; run in verbose mode for details
ok
testHELP (test.test_smtplib.DebuggingServerTests) ... ok
testNOOP (test.test_smtplib.DebuggingServerTests) ... ok
testNotImplemented (test.test_smtplib.DebuggingServerTests) ... ok
(...)
----------------------------------------------------------------------
Ran 32 tests in 23.664s
OK
===============================
I propose to always run the tests in verbose mode, write the output into a buffer, but only display the output on failure (or ignore the output on success).
Attached patch simplifies regrtest.py usage: replace 4 verbose levels (no verbose option, -v, -w, -W) by only 2 (no verbose option, -v). Always display the full output in case of an error (as we used -w before): no more "multiple error occured" without output trap, no more "oh, rerunning the test doesn't fail" trap. The -v option works as before (directly write the output in verbose mode).
regrtest is much more verbose than before in case of a failure, but I prefer too much information than no information when I try to debug something. If it is too much verbose by default, I can try to use 3 verbose levels (e.g. don't display the full output if only one test failed).
If the patch is accepted, the devguide should also be patched.

Another example (yesterday):
------
[355/356/2] test_subprocess
...
Re-running test test_subprocess in verbose mode
...
Ran 228 tests in 322.313s
OK (skipped=20)

New patch updated according to bitdancer's comment on IRC: only change the -W option. With the patch, -W only runs the test once but captures the output.
The main difference with my patch is that all output is written to stderr, even if the captured output was written into stdout. I don't want to capture stdout and stderr in two differents stream, I prefer to keep the original output order. In case of a failure, the output only concerns a failure.

I will not backport the change in Python 2.7, because regrtest already captures stdout (but not in verbose mode), and it checks that the output is empty.

Hmm. I thought Antoine got rid of the output checking when he added -j support. Well, he was the one who did it, anyway, so there may be a change set you could backport to get rid of the output checking if you want to backport this to 2.7.

One more time, commit messages using the present tense are ambiguous: when you write “runtest() truncates the StringIO stream before a new test“, it’s not clear at all whether you describe the previous, incorrect behavior or the new, fixed one. These phrasings are better:
“X used to do Y” (old behavior)
“X now does Z” (new)
“make X do Z” (new)

You can guess by reading the patch.

hg annotate doesn't display the changelog, only the commit number or

... or when looking at the issue tracker. Yes, one can probably figure out the intent by looking at the whole patch but it's kind of rude to force people to do that. That's what the commit message is there for: to give a brief, unambiguous summary of what the change is about.
