MAGIK (PROGRAMMING LANGUAGE)
•
•
•
•
•
Still the primary programming environment
Excellent backward language compatibility (> 99%)
Code compiled to Java VM
Noticeably faster
Integration with Java
libraries
© Globema 2015. All rights reserved.
16
DATABASE (VMDS)
• No functional changes
Practically 100% backward compatible
• Faster access
API read even 4x times faster in some scenarios
• Same communication protocol
Improvements planned after 5.0 release
• Concurrent access for 4.x and 5.0 clients
© Globema 2015. All rights reserved.
17
USER INTERFACE
• New set of UI elements – SWIFT
New icons, different modern look
Emulation of “old” components from version 4.x
4.3
• No 100% backward compatibility
Most of the code works without changes
• Whole user interface needs review
5.0
Large number of small changes
© Globema 2015. All rights reserved.
18
USER INTERFACE - CHALLENGES
• Emulation is not perfect
Documentation does not clearly describe all differences
How to find the missing 1%
• Keyboard handling
Different notifications
Some shortcuts do not work
• Performance
© Globema 2015. All rights reserved.
19
THREADING
• Threads are different in Smallworld 5
Native Java threads
Pre-emptive thread switching
• Basic conversion well-documented
• Issues
UI synchronization
Some features are missing
In one case significant application re-design was needed
© Globema 2015. All rights reserved.
20
TRIVIA
• Magik images are gone
closed image
open image
 compile code into jars
 use database contexts
• Conversion of icons .ico  .png
• Keep Smallworld 5.0 directory locally
Disable localisation products if possible (to be fixed in 5.1)
• perform()
Do not redefine perform() method in Magik
Even a single re-definition can seriously degrade DB write performance
© Globema 2015. All rights reserved.
21
DEVELOPMENT ENVIRONMENT
• MDT – limited experience
Difficult to change developers’ habits
• Emacs
Not officially supported – but still works!
Including class browser
• Native Java diagnostic tools (performance, memory)
• Developer tools not available in 5.0
© Globema 2015. All rights reserved.
22
OTHER CHANGES
• Documentation and context help
Based on HTML 5
Context help delivered with application
Documentation available on-line on GE servers
• Google Maps and StreetView
Built in the application
Address search
StreetView integrated with other tools (e.g. trail)

24
LNI – version 5.0

25
LNI - RESULTS
• Product upgraded, tested and released
• Much more changes than initially anticipated
We have started early – platform was not stable at that time
UI changes and threading
Unexpectedly large number of small changes/corrections
A number of performance issues identified together with GE
Platform performance improved

27
NETWORK VIEWER FOR DH.GIS
• NV to replace a legacy web application
• New features available in NV 5.0.1
Printing improvements
Large internals
• Partial upgrade of DH.GIS application
Data model and API level only
No changes in application-level Magik code between NV 4.3.2 and 5.0.1
Migration of some low-level modules needed
© Globema 2015. All rights reserved.
28
PNI MODULES
• PRM, ONA, CATV Design
Products upgraded and
released on 5.0
Next release on 5.1 – Q2 2016
• Upgrade experience like with LNI
Few new core issues encountered (fixed fonts, keyboard handling)
More heavy use of threads  more work needed
• Products to be maintained on PNI 4.3
© Globema 2015. All rights reserved.
29
SMALLWORLD 5.1
• Faster start-up
• Bug fixes
• Minimal functional changes
Same data model
Upgrade 4.x  5.1 as easy as (or easier than) 4.x  5.0
• Development tools are back

HOW TO START?
• Difficult to assess upgrade
costs
• Upgrade in stages
• Client application upgrade

32
HOW TO START?
• Difficult to assess upgrade
costs
Primary areas – UI and threading
• Upgrade in stages
Start with the low-hanging fruit
Database-level and API should be easy
NV/NIG/GSS may be a good candidate
Can run simultaneously with 4.x clients
• Client application upgrade

SUMMARY
• Mature/proven platform (Java VM)
• Excellent Magik compatibility
• Minimal changes to the architecture
Ease of migration
• UI changes
Needs review and fixes
• Performance
Possible to achieve decent performance, but it needs work
