Clojure 1.6 正式版发布，此版本更新内容如下： 1 兼容性和依赖关系1.1 JDK 版本更新Clojure now builds with Java SE 1.6 and emits bytecode requiring Java SE 1.6 instead of Java SE 1.5. [CLJ-1268] 1.2 ASM 库更新The embedded version of the ASM bytecode library has been upgraded to ASM 4.1. [CLJ-713] 1.3 提升 "Alpha" 特性The following features are no longer marked Alpha in Clojure: Watches - add-watch, remove-watch Transients - transient, persistent!, conj!, assoc!, dissoc!, pop!, disj! Exception data - ex-info, ex-data Promises - promise, deliver Records - defrecord Types - deftype Pretty-print tables - print-table
2 新特性和改进记录2.1 Java API2.2 Map destructuring extended to support namespaced keys
2.3 New "some" operations
2.4 Hashing Related tickets for dev and regressions: CLJ-1328Make several Clojure tests independent of ordering CLJ-1331Update primitive vectors to use Murmur3 hash CLJ-1335Update hash for empty PersistentList and LazySeq CLJ-1336Make hashing mixing functions available in Clojure CLJ-1338Make Murmur3 class public CLJ-1344Update mapHasheq to call Murmur3 algorithm CLJ-1348Add hash-ordered-coll and hash-unordered-coll CLJ-1355Restore cached hashCode for Symbol and (uncached) hashCode for Keyword CLJ-1365Add type hints for new collection hash functions
2.5 bitops2.6 clojure.test 3 功能增强3.1 PrintingCLJ-908Print metadata for functions when print-meta is true and remove errant space at beginning. CLJ-937pprint cl-format now supports E, F, and G formats for ratios.
3.2 错误信息CLJ-1248Include type information in reflection warning messages CLJ-1099If non-seq passed where seq is needed, error message now is an ExceptionInfo with the instance value, retrievable via ex-data. CLJ-1083Fix error message reporting for "munged" function names (like a->b). CLJ-1056Handle more cases and improve error message for errors in defprotocol definitions. CLJ-1102Better handling of exceptions with empty stack traces. CLJ-939Exceptions thrown in the top level ns form are reported without file or line number.
3.3 文档字符串CLJ-1164Fix typos in clojure.instant/validated and other internal instant functions. CLJ-1143Correct doc string for ns macro. CLJ-196Clarify value of file is undefined in the REPL. CLJ-1228Fix a number of spelling errors in namespace and doc strings. CLJ-835Update defmulti doc to clarify expectations for hierarchy argument. CLJ-1304Fix minor typos in documentation and comments CLJ-1302Mention that keys and vals order are consistent with seq order
3.4 性能CLJ-858Improve speed of STM by removing System.currentTimeMillis. CLJ-669clojure.java.io/do-copy: use java.nio for Files commitReduce overhead of protocol callsites by removing unneeded generated cache fields.
3.5 其他改进CLJ-908Make default-data-reader-fn set!-able in REPL, similar to data-readers. CLJ-783Make clojure.inspector/inspect-tree work on sets. CLJ-896Make browse-url aware of xdg-open. CLJ-1160Fix clojure.core.reducers/mapcat does not stop on reduced? values. CLJ-1121-> and ->> have been rewritten to work with a broader set of macros. CLJ-1105clojure.walk now supports records. CLJ-949Removed all unnecessary cases of sneakyThrow. CLJ-1238Allow EdnReader to read foo// (matches LispReader behavior). CLJ-1264Remove uses of _ as a var in the Java code (causes warning in Java 8). CLJ-394Add record? predicate. CLJ-1200ArraySeq dead code cleanup, ArraySeq_short support added. CLJ-1331Primitive vectors should implement hasheq and use new hash algorithm CLJ-1354Make APersistentVector.SubVector public so other collections can access CLJ-1353Make awt run headless during the build process
4 Bug 修复
CLJ-1018Make range consistently return infinite sequence of start with a step of 0. CLJ-863Make interleave return () on 0 args and identity on 1 args. CLJ-1072Update internal usages of the old metadata reader syntax to new syntax. CLJ-1193Make bigint and biginteger functions work on double values outside long range. CLJ-1154Make Compile.java flush but not close stdout so errors can be reported. CLJ-1161Remove bad version.properties from sources jar. CLJ-1175Fix invalid behavior of Delay/deref if an exception is thrown - exception will now be rethrown on subsequent calls and not enter a corrupted state. CLJ-1171Fix several issues with instance? to make it consistent when used with apply. CLJ-1202Protocol fns with dashes may get incorrectly compiled into field accesses. CLJ-850Add check to emit invokePrim with return type of double or long if type-hinted. CLJ-1177clojure.java.io URL to File coercion corrupts path containing UTF-8 characters. CLJ-1234Accept whitespace in Record and Type reader forms (similar to data literals). CLJ-1233Allow ** as a valid symbol name without triggering dynamic warnings. CLJ-1246Add support to clojure.reflect for classes with annotations. CLJ-1090Indirect function calls through Var instances fail to clear locals. CLJ-1076pprint tests fail on Windows, expecting \n. CLJ-766Make into-array work consistently with short-array and byte-array on bigger types. CLJ-1285Data structure invariants are violated after persistent operations when collision node created by transients. CLJ-1222Multiplication overflow issues around Long/MIN_VALUE CLJ-1118Inconsistent numeric comparison semantics between BigDecimals and other numerics CLJ-1125Clojure can leak memory in a servlet container when using dynamic bindings or STM transactions. CLJ-1082Subvecs of primitve vectors cannot be reduced CLJ-1301Case expressions use a mixture of hashCode and hasheq, potentially leading to missed case matches when these differ. CLJ-983proxy-super does not restore original binding if call throws exception CLJ-1176clojure.repl/source errors when read-eval bound to :unknown CLJ-935clojure.string/trim uses different definition of whitespace than triml and trimr CLJ-1058StackOverflowError on exception in reducef for PersistentHashMap fold CLJ-1328Fix some tests in the Clojure test suite to make their names unique and independent of hashing order CLJ-1339Empty primitive vectors throw NPE on .equals with non-vector sequential types CLJ-1363Field access via .- in reflective case does not work CLJ-944Compiler gives constant collections types which mismatch their runtime values CLJ-1387reduce-kv on large hash maps ignores reduced result
