Re: [Wireshark-dev] Intermittent Builder Windows Petri Dish x64 failed (failed ctest) failures seriously annoying.

The failures don't appear to be limited to the test steps. Earlier we had the 
following cluster of failures:

x86 builder:

BranchBuild Step   StartStop
master 1680 ctest   08:38:1809:02:45
master-3.2  365 ctest   08:27:0208:55:58
master-3.0  133 WiX pkg 07:56:0408:16:38
master-2.6  221 NSIS pkg07:43:5908:05:01

x64 builder:

BranchBuild Step   StartStop
master 1604 ctest   08:22:5808:47:45
master-3.2  369 ctest   08:24:0908:48:15
master-3.0  322 NSIS pkg07:36:1407:57:08
master-2.6  212 WiX pkg 07:35:2307:59:54

Each builder is an EC2 instance at AWS, and the AWS console shows that the CPU 
on each instance was 100% during that time. The obvious fix is more and/or 
faster Windows builders), but I also noticed that tshark does more work than it 
should in many cases. If I open Process Monitor and set the filters

- Operation contains "Process Create"
- Path contains ""

and run test/test.py, procmon shows that we create 5573 process for 576 tests. 
For the decryption suite,  procmon shows 970 processes for 89 tests. Most of 
the created decryption processes are extcaps, which seems odd for those 
particular tests. If I rename the extcap directory, procmon shows that 97 
process are created and the suite runs much more quickly (50s vs 93s).

The tests are run all in parallel, and I'm not sure if the PD is a spot or
reserved instance which might affect available CPU cycles.

You're right, it's not the test I pointed out. However it worked fine
before, then I would check the host to see if it's suffering.

Re: [Wireshark-dev] Intermittent Builder Windows Petri Dish x64 failed (failed ctest) failures seriously annoying.

2020-07-02 Thread Dario Lombardo 
This looks to be the failing test

9: test_s_lt_2 (suite_dfilter.group_integer.case_integer) ... ok
 9/34 Test  #3: suite_decryption ...***Timeout 630.47 sec
test 12
  Start 12: suite_dfilter.group_membership

It fails for timeout. Looking at the code of the test itself it looks
very straight forward:

def test_s_lt_2(self, checkDFilterCount):
dfilter = "ntp.precision < 245"
checkDFilterCount(dfilter, 0)

Basically this test opens a file and checks that the number of
filtered packets is 0. Not a really hard test. Since the test fails
for timeout, and moreover intermittently, I would say that the builder
host is suffering. Can someone with shell access check if the host is
running fine?

The decryption test might need a bigger timeout, currently at 600 seconds:

9/34 Test  #3: suite_decryption ...***Timeout 630.47 sec

Hi,

We have intermittent false petri dish failures. Can someone with insight
into the tests have a look?

Best regards
