| 30 | ## Features |
|---|
| 31 | |
|---|
| 32 | * Make LispStackFrame.UNAVAILABLE_ARG a singleton object, |
|---|
| 33 | and lazily create the little used portions of the Lisp stack. |
|---|
| 34 | |
|---|
| 35 | Aggressively cache and control the use of memory by the underlying |
|---|
| 36 | Lisp stack frame representation by introducing the private |
|---|
| 37 | LispThread.StackFrame and LispThread.StackSegments classes. |
|---|
| 38 | |
|---|
| 39 | Contributed by Dmitry Nadezhin. |
|---|
| 40 | |
|---|
| 41 | LispStackFrame object are allocated on every |
|---|
| 42 | LispThread.execute(...) . However, they are seldom [accessed] |
|---|
| 43 | ([... verify via] inspect[tion of the] stack trace). This patch |
|---|
| 44 | delays allocation of LispStackFrame? objects until they are |
|---|
| 45 | requested. Raw information about stack frames is stored in |
|---|
| 46 | stack. Stack is an Object[] array (more precisely a list of [...]4 |
|---|
| 47 | [Mib] Object[] arrays). |
|---|
| 48 | |
|---|
| 49 | ME: We are going to need a way to try to less agressively grab 4Mib |
|---|
| 50 | chunks in low memory situations. |
|---|
| 51 | |
|---|
| 52 | Memory profiling of ABCL shows that the classes with largest |
|---|
| 53 | allocation count are org.armedbear.lisp.LispStackFrame and |
|---|
| 54 | org.armedbear.lisp.LispStackFrame.UnavailableArgument. |

|---|
| 60 | |
|---|
| 61 | * ASDF 3.0.1.94 shipped with the implementation |
|---|
| 62 | |
|---|
| 63 | * per function call stack and memory exception handler in CL:COMPILE |
|---|
| 64 | |
|---|
| 65 | Inline calls to jrun-exception-protected (used by handler-bind to |
|---|
| 66 | catch out of memory conditions). This commit saves generation |
|---|
| 67 | roughly 50 cls files. |
|---|
| 68 | |
|---|
| 69 | [r14552]: http://abcl.org/trac/changeset/14552 |
|---|
| 70 | |
|---|
| 71 | * SYS:SHA256 audited |
|---|
| 72 | |
|---|
| 73 | The functionality if the SYS:SHA256 algorithim has been audited for |
|---|
| 74 | use on inputs of single for files with recently shipping ORCL Java 7 |
|---|
| 75 | implementations (through jdk-1.7.0_51). |
|---|
| 76 | |
|---|
| 77 | [r14582]: http://abcl.org/trac/changeset/14582 |
|---|
| 78 | |
|---|
| 79 | * Connect to NetBeans controlled JDWP via SLIME |
|---|
| 80 | |
|---|
| 81 | The Netbeans IDE configuration now includes a way to connect to |
|---|
| 82 | the running-under-jdb ABCL via SLIME. One needs a version of |
|---|
| 83 | SLIME able to be loaded from its 'swank.asd' definition. |
|---|
| 84 | |
|---|
| 85 | * Install 'abcl.jar' and 'abcl-contrib.jar' locally as Maven artifacts |
|---|
| 86 | |
|---|
| 87 | The Ant `abcl.mvn.install` target now installs build artifacts |
|---|
| 88 | into the local Maven repository (Olof-Joachim Frahm) |
|---|
| 89 | |
|---|
| 90 | [r14579]: http://abcl.org/trac/changeset/14606 |
|---|
| 91 | |
|---|
| 92 | ## Compatibility |
|---|
| 93 | |
|---|
| 94 | * CL:DIRECTORY |
|---|
| 95 | |
|---|
| 96 | The implementation specific :RESOLVE-SYMLINKS argument to the ANSI |
|---|
| 97 | DIRECTORY function has been changed to nil. This implements |
|---|
| 98 | behavior closer to SBCL and guarantees that a DIRECTORY operation |
|---|
| 99 | will not signal a file error. |

|---|
| 103 | |
|---|
| 104 | ## Fixes |
|---|
| 105 | |
|---|
| 106 | * Fix CL:SLEEP for intervals less than a millisecond. |
|---|
| 107 | |
|---|
| 108 | For intervals less than or equal to a nanosecond, including an |
|---|
| 109 | interval of zero, the current thread merely yields execution to |
|---|
| 110 | other threads. |

|---|
| 122 | |
|---|
| 123 | #### abcl-asdf |
|---|
| 124 | |
|---|
| 125 | * Now working with both Maven 3.0.x and 3.1.x. Thanks to Anton for |
|---|
| 126 | the help! |
|---|
| 127 | |
|---|
| 128 | [ticket-328]: http://abcl.org/trac/ticket/328 |
|---|
| 129 | |
|---|
| 130 | * cache Maven dependency resolution to avoid repeated lookups. |
|---|
| 131 | |
|---|
| 132 | Instead of calling ABCL-ASDF:RESOLVE in both the ASDF COMPILE-OP |
|---|
| 133 | and LOAD-OP, we now cache the result of invocation in COMPILE-OP |
|---|
| 134 | and add this value in the LOAD-OP phase. Contributed by Cyrus |
|---|
| 135 | Harmon. |

| 138 | |
|---|
| 139 | #### jna |
|---|
| 140 | |
|---|
| 141 | Now references jna-4.0.0. Some incompatibility with CFFI ([in |
|---|
| 142 | progress with fixing upstream][cffi-easye]). |
