Filename bug with automated tests

[J. Max Mena]

As discussed earlier, I'm writing up a ticket to document some strange behavior I was seeing with our machine that's running the automated tests regularly.

As is now, here's what the crontab looks like:

#Run the Daily Automated Tests
0 19 * * * /home/xpra/bin/runautomatedtests.sh
#Run the TC Tests
30 0 * * * /home/xpra/bin/runtctests.sh
#Run the Bandwidth Tests
30 4 * * * /home/xpra/bin/runbandwidthtests.sh
#Update Xpra daily after running the tests
0 9 * * * /home/xpra/bin/updatexpra.sh

(Among a few other commented out scripts that are no longer enabled)

Here's what the top of runautomatedtests.sh looks like:

#!/bin/bash
export PATH=/usr/bin:/usr/sbin:/bin:/sbin
export DISPLAY=:0
date="$(date +%Y%m%d%k%M)"
~/tests/xpra/test_measure_perf.py config_just_av ~/tests/xpra/data/automated/av_${date}_2_1.csv 1 2 2>&1 | tee ~/tests/xpra/data/automated/logs/av_${date}_2_1.log

And this one works correctly - every morning it runs all the tests and everything outputs correctly. The problematic one was runbandwidthtests.sh and runtctests.sh.

Here's the top of runbandwidthtests.sh:

#!/bin/bash
#Init variables
export PATH=/usr/bin:/usr/sbin:/bin:/sbin
export DISPLAY=:0
#export PYTHONPATH=/usr/lib/python2.7
date="$(date +%Y%m%d%k%M)"

#Turn on mild bandwidth limits - start with 50mbits
sudo tc qdisc add dev lo root netem rate 50mbit

#Run the test
~/tests/xpra/test_measure_perf.py config_just_av ~/tests/xpra/data/automated/av_${date}_2_1_50mbit.csv 1 2 2>&1 | tee ~/tests/xpra/data/automated/logs/av_${date}_2_1_50mbit.log

And here's the top of runtctests.sh:

#!/bin/bash
#Init variables
export PATH=/usr/bin:/usr/sbin:/bin:/sbin
export DISPLAY=:0
date="$(date +%Y%m%d%k%M)"

#Turn on light TC
sudo tc qdisc add dev lo root netem delay 25ms 10ms 25%

#Run the tests
~/tests/xpra/test_measure_perf.py config_just_av ~/tests/xpra/data/automated/av_${date}_2_1_lighttc.csv 1 2 2>&1 | tee ~/tests/xpra/data/automated/logs/av_${date}_2_1_lighttc.log
~/tests/xpra/test_measure_perf.py config_just_glx ~/tests/xpra/data/automated/glx_${date}_2_1_lighttc.csv 1 2 2>&1 | tee  ~/tests/xpra/data/automated/logs/glx_${date}_2_1_lighttc.log
~/tests/xpra/test_measure_perf.py config_just_x11 ~/tests/xpra/data/automated/x11_${date}_2_1_lighttc.csv 1 2 2>&1 | tee  ~/tests/xpra/data/automated/logs/x11_${date}_2_1_lighttc.log

And for some odd reason the last two don't output their files correctly - I end up with a file with no file ending that has the pattern prefix_date with the rest of the filename argument as one of the start commands. For reference, here's a snippet from the file av_20180408:

"png (vlc sound visual - None - None - unthrottled - via tcp)", "xpra", "2.3", "2.3", "030_2_2_bareedgeofwifi.csv 2 2", "Unversioned directory", "png", -1, -1, "llvmpipe (LLVM 4.0, 256 bits)", "vlc sound visual", 120, 1523189767.45, "8x Intel Xeon CPU E3-1230 v3 @ 3.30GHz", "x86_64", "4.14.4-200.fc26.x86_64", "X.Org X Server 1.19.3", "llvmpipe (LLVM 4.0, 256 bits)", "unknown", "1024x768", , , "tcp", 0, 0, 0, 81, 5230, 154, 5172974, 24, 14140132, 36414063, 45567324, 0, 884, 0, 4947850, 0, "", "", "", "", 44.0, 5.3, 14, 1181, 118, 57.3, 9.6, 7, 1429, 97, 12, 42, 76, , , , , , , , , , , , , 0, 15, 34, , , , , , 

This file is clearly a .CSV, and the first part contains 030_2_2_bareedgeofwifi.csv 2 2, which should not be in the arguments.

So this is what I'm seeing. As a workaround I changed the date variable to not include the time, and only the date:

date="$(date +%Y%m%d)"

Looks like a case of missing quotes. I'm sure smo can help you there.

Personally, I would use something like:

pushd ~/tests/xpra
./test_measure_perf.py config_just_av "./data/automated/av_${date}_2_1_lighttc.csv"
popd

Also, if you are adding tc rules in a script, you should ensure you remove them at the end using an exit trap.
If somehow they don't get removed, this could really badly skew the other results.

[J. Max Mena]

I'm gonna intercept this one from Smo - I implemented the changes you suggested:

• Exit trap for TC rules

• Quotes around .CSV output filename

• pushd/popd functionality

That has completely solved this issue. I'm gonna go ahead and close this ticket as fixed.

[Antoine Martin]

We never got the fixed script..
