end of file error #7

Closed eunsungc closed 8 years ago

eunsungc commented 8 years ago

After adding xdd execution results, errors occur from time to time. Trying to figure out where the bug is: 1) receiver side? 2) sender side?

eunsungc commented 8 years ago

It turns out that bug is on the sender side. Tests: globus-url-copy ftp: to file: --> error globus-url-copy file: to ftp: --> no error

From globus_gridftp_server_control.h

/**

This type indicates to the library in what direction a user data object
can be used for transfer. STOR is for receiving data, RETR is for
sending data, and BI is for either direction. When connecting a data
object the user will use pass in one of these 3 values. see

No error when non-threaded version server is running.

eunsungc commented 8 years ago

Due to assert failure in globus_i_gfs_data_request_send() function.
