|---|
| 28 | <dt>Faster initial startup</dt> |
|---|
| 29 | <dd>To achieve faster startup times - required for example by |
|---|
| 30 | Google App Engine which restarts the servlet regularly - |
|---|
| 31 | ABCL now delays reflection calls associated function-class |
|---|
| 32 | resolution by resolving functions upon their first call.</dd> |
|---|
| 33 | <dt>Portable FASLs</dt> |
|---|
| 34 | <dd>As part of a fixed bug, ABCL now has portable fasls: all |
|---|
| 35 | fasls use UTF-8 as their encoding, instead of the system dependent |
|---|
| 36 | default encoding. This should help easy deployment and deployment |
|---|
| 37 | to Google App Engine. Because of this change, the FASL version |
|---|
| 38 | number has increased to 35.</dd> |
|---|
| 39 | <dt>Faster special variable lookup</dt> |
|---|
| 40 | <dd>As part of the continued search for performance improvements |
|---|
| 41 | has the lookup mechanism for special variable value lookup been |
|---|
| 42 | changed. Part of this change is the introduction of an API to |
|---|
| 43 | record unbinding marks for unwinding later on.</dd> |
|---|
| 44 | <dt>Improved reliability with exceptions</dt> |
|---|
| 45 | <dd>Out-of-memory or Stack-overflow conditions can be handled |
|---|
| 46 | programatically by binding handlers for them in handler-bind. |
|---|
| 47 | In addition, program execution used to continue on caught but |
|---|
| 48 | unhandled generic (Throwable) exceptions. This is no longer |
|---|
| 49 | the case: only specific exceptions get caught, or the generic |
|---|
| 50 | exception is handled, preventing execution from 'just' continuing.</dd> |
|---|
| 51 | <dt>Fixed memory leak with functions-with-documentation</dt> |
|---|
| 52 | <dd>Functions with documentation going out of scope because of |
|---|
| 53 | being unused were incorrectly not GC-ed. This has now been resolved.</dd> |
