+# BUG#39701: Mixed binlog format does not switch to row mode on LOAD_FILE
+#
+# DESCRIPTION
+#
+# Problem: when using load_file string function and mixed binlogging format
+# there was no switch to row based binlogging format. This leads
+# to scenarios on which the slave replicates the statement and it
+# will try to load the file from local file system, which in most
+# likely it will not exist.
+#
+# Solution:
+# Marking this function as unsafe for statement format, makes the
+# statement using it to be logged in row based format. As such, data
+# replicated from the master, becomes the content of the loaded file.
+# Consequently, the slave receives the necessary data to complete
+# the load_file instruction correctly.
+#
+# IMPLEMENTATION
+#
+# The test is implemented as follows:
+#
+# On Master,
+# i) write to file the desired content.
+# ii) create table and stored procedure with load_file
+# iii) stop slave
+# iii) execute load_file
+# iv) remove file
+#
+# On Slave,
+# v) start slave
+# vi) sync it with master so that it gets the updates from binlog (which
+# should have bin logged in row format).
+#
+# If the the binlog format does not change to row, then the assertion
+# done in the following step fails. This happens because tables differ
+# since the file does not exist anymore, meaning that when slave
+# attempts to execute LOAD_FILE statement it inserts NULL on table
+# instead of the same contents that the master loaded when it executed
+# the procedure (which was executed when file existed).
+#
+# vii) assert that the contents of master and slave
+# table are the same
