[LTP] Test case float_trigo Reading dsin error

[LTP] Test case float_trigo Reading dsin error

[fixed-term.Islam.Tammam]

I have faced recently an issue with an imx6 target which is running 
kernel version "3.14" for the below tests:

float_bessel
float_exp_log
float_power
float_trigo

these tests are failing and giving an error of thread termination "No 
such file or directory". Please find a log below. any reason why that 
happened and how can this be solved ?

target:/opt/ltp/testcases/bin# ./float_trigo
float_trigo 1 TPASS : Test passed
float_trigo 1 TFAIL : main.c:292: thread 100 (sin) terminated
unsuccessfully 0 errors/0 loops
FAIL: sin: reading dsin, No such file or directory
float_trigo 2 TFAIL : main.c:292: thread 101 (sin) terminated

unsuccessfully 0 errors/0 loops
FAIL: tan: reading dtan, No such file or directory
float_trigo 41 TFAIL : main.c:41: Test failed

I have no idea why the generation of files such asin, atan, acos works 
but doesn't work for dsin and dtan ?

Looks like it starts to fail in the middle of the test, that is really
strange. Have you checked that gensin and gentan binaries are working
fine (create non-empty rsin and dsin as well as rtan and dtan
files)?

[LTP] Test case float_trigo Reading dsin error

[fixed-term.Islam.Tammam]

Hi Cyril,
what is the format of dsin and dtan files ? i.e how do they look like 
since they are binaries i have no clue for creating them.

i just had a look at the link here
https://github.com/linux-test-project/ltp/tree/master/testcases/misc/math/float/trigo

to be able to generate the data files "manually" , but such data files 
shall be generated automatically when running the ./float_trigo test 
cases itself. do you have an idea how so that happens ? and what is the 
destination directory of the generated files , since i checked 
/opt/ltp/testcases/bin but didn't find any data files generated there.

No idea either, you would have to look into the source code that
prepares these in trigo/gen*.c

Looking into the source code the generators are called from main.c which
executes line composed as: ("cd %s; %s/%s %s", datadir, bin_path,
GENERATOR, bin_path) and the generators create files in $CWD and unless
there is a -D parameter passed to the test the datadir defaults to ".".
The runtest/math file does cd $LTPROOT/testcases/bin before it executes
the test so I guess that by default these files end up in the
/opt/ltp/testcases/bin/ directory. But all of that code is quite messy
so I may be as well wrong.
