Shahbaz updated SSHD-1042:
--------------------------
Description:
*This are the below commands which prevent the execution of process for the
user at instance level relating to permission of open, read, write, opendir,
readdir, remove, rename, makedir, removedir respectively.*
*SSH_FXP_OPEN*
*SSH_FXP_READ*
*SSH_FXP_WRITE*
*SSH_FXP_OPENDIR*
*SSH_FXP_READDIR*
*SSH_FXP_REMOVE*
*SSH_FXP_RENAME*
*SSH_FXP_MKDIR*
*SSH_FXP_RMDIR*
*But the command for* *SSH_FXP_READDIR is not executed as it directly closes
the connection. This connection is closed because while throwing the exception
it directly calls destroy method from filesystem. Is there any workaround to
inhibit its execution when we extend sftpsubsytem class where exception is
thrown.***
*While reading the directory when SH_FXP_READDIR is applied, the operation is
interrupted, as it evokes the destroy function to close the connection directly
when an IOException is thrown. The issue is how can we make sure the destroy
function is not called, when exception is thrown in a class which extends
SFTPSubsystem.*
*Below attached are the images which shows how destroy is invoked in both
maverick and apache case.*
