VELOC_Route_file returns empty string during restart #5

Closed adammoody closed 4 years ago

adammoody commented 5 years ago

With the file-based method, during a restart, the app calls VELOC_Route_file to get the path to each of its checkpoints files. However, veloc currently returns "" in this case, due to a check as to whether the library is in an active checkpoint state.

[ERROR 804727076878] [.../src/lib/client.cpp:145:route_file] must call checkpoint_begin() first

We need to also enable this to work during restart, i.e. for the following sequence,

VELOC_Init()
VELOC_Restart_test()
VELOC_Restart_begin()
VELOC_Route_file()
VELOC_Restart_end()
