enabling dmesg log in libc library for golang sqlite repo

[Srinivas Pokala]

Hi  all,

I am working sqlite in pure go repo, where some of tcl test cases getting fail. In order to check read/write thing on libc library How to log dmesg information in libc functionality.

I have tried adding -tags=libc.dmesg to test go test  run command and adding dmesg("") API in Xread/Xwrite functions in libc library, I am not able to see dmesg logging in the /tmp/libc.log file. The file is generating and maintaining each run of testsuite time stamp.

Regards,

Srinivas

Hi Srinivas.

The golang-dev list is for the developers of Go. For other questions
please use the sqlite issue tracker or the golang-nuts mailing list,
thanks.

Wrt the tags, can you please show the exact command you have used?
I'll subsequently send you another off-list email with an example from
my computer once I get to it.

Hi Jan,

Thank's for the info, I have used  $ go test -timeout 24h -v -run Tcl  -Xtags=libc.dmesg -suite full 2>&1 | tee log-full .

In the sqlite library there are some of sysfault test cases which failing below is the error verbose
