Changes to 1.38.3:
- This is mainly a bug release fix. In addition, the multiple drive
reservation algorithm has been rewritten.
-- Implement load balancing code.
+- In addition, the method of handling waiting for tapes to be
+ mounted and the mount messages has been modified.
+ (the above two items are a potential source of problems).
+- Simplify code in askdir.c that waits for creating an appendable
+ volume so that it can handle multiple returns from the wait code.
+- Modify the wait code to permit multiple returns.
+- Return a zero when "autochanger drives" is called and
+ it is not an autochanger.
+- Make rewind_dev() a method taking a DCR as an argument.
+ This permits closing and reopening the drive if the
+ rewind fails as happens if the drive was loaded while the
+ file descriptor was open. This refreshes the file descriptor.
+- Remove the ST_OPENED flag and always rely on fd < 0 for knowing
+ if the device is open or not. This should eliminate
+ Arnos problem.
+- Return error if reserve cannot find at least one suitable device.
+- Make wait_for_sysop() return correct state information.
+- Fix Win32 state file problem. write was not using compat
+ code. This should fix bug #500.
+- Modify gui on command to set only GUI mode and not batch.
+- Modify .messages command to always print messages regardless
+ of the mode.
+- If GUI mode is on, suppress automatic printing of
+ You have messages.
+- Modify restore command in wx-console to set gui on and to use
+ only .messages instead of messages. Hopefully this fixes bug
+ #514.
+- Implement load balancing code with multiple drive autochangers.
- Rewrite reservation algorithm again. Rename variables to be
more logical, add HEARTBEAT with Director, allow cancel of
jobs stuck in reservation, add last resourt any_drive.
