There are some long loops and sleeps in unit tests, it will cost a
very long time to run all unit tests, especially run in TSAN mode.
This patch speed up unit tests by shortening long loops and sleeps,
on my environment all unit tests finished in 1 minite. It's useful
to do basic functional unit tests.
You can switch to run in this mode by adding a new environment variable
'DORIS_ALLOW_SLOW_TESTS'. For example, you can set:
export DORIS_ALLOW_SLOW_TESTS=1
and also you can disable it by setting:
export DORIS_ALLOW_SLOW_TESTS=0
Use static local variable instead of create it every calls.
Time cost of the new added unit benchmark test could reduce
from about 60 seconds to 10 seconds.
The parameter 'part' of parse_url function does not support lower case, and parse protocol not right.
And This function does not support parse 'port'.
This PR tries to make parse_url function case insensitive and support parse 'port'.
