1.11 中的 fastmath 出错

在 Clojure 由
编辑 由

当使用 Clojure 1.11 编译（通过 athos/clj-check）一些使用 org.clojure/math.combinatorics 的代码时，我遇到了以下异常。相同的代码使用 Clojure 1.10.3 编译时没有任何警告或错误。

这是预期的吗？

相关代码在这里：这里，可以通过在 deps.edn 中切换 Clojure 版本为 1.10.3 和 1.11.0，然后在命令行中执行 clj -M:check 来展示这个问题。

此外，这是在 OpenJDK 运行时环境 Temurin-17.0.2+8（构建 17.0.2+8）的 macOS 12.3（64位 Intel）上发生的，如果有帮助请告知。

更简单的但足以重现的示例

clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.11.0"} clojure2d/clojure2d {:mvn/version "1.4.3"}}}'

;; then
(require '[clojure2d.core :as c2d] :verbose)

产生

user=> (require '[clojure2d.core :as c2d])

更新到最新的 fastmath 版本似乎解决了绝对值碰撞问题。

clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.11.0"} clojure2d/clojure2d {:mvn/version "1.4.3"} generateme/fastmath {:mvn/version "2.1.6"}}}'

通常情况下，如果库中已经存在相同功能的函数，仅在核心库中添加新功能只会产生警告而不会报错。我认为这与fastmath.protocols声明了一个abs函数和fastmath.core中进行的变量交换有关。我目前还不能完全理解这些操作的序列，但最近在fastmath中添加的核心排除似乎避免了这个问题。

因此，在此处添加一个更具体的fastmath版本就足够修复这个问题了，但clojure2d也应该更新。

为clojure2d添加了问题：[https://github.com/Clojure2D/clojure2d/issues/19](https://github.com/Clojure2D/clojure2d/issues/19)

谢谢！在我等待Clojure2D更新的时候，我会强制使用新的fastmath版本。

完成了！已经发布了Fastmath 2.1.8和Clojure2d 1.4.4。

感谢大家的调查。确实，我忽视了更新原始数学路径的排除列表。这已经在fastmath 2.1.8和Clojure2d 1.4.4中修复了。

$ clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.11.0"} clojure2d/clojure2d {:mvn/version "1.4.4"}}}'

在 Clojure 1.10.3 中，以下命令会得到什么结果？

clj -Sforce -M:check

只想确保您在比较时没有使用缓存的类路径。这几乎好像有点依赖性问题。

此外，请发布以下内容

clj -X:deps tree :aliases ‘[:check]’

（您需要较新的 CLI 才能实现这一点）

绝对确定这不是本地缓存问题，因为当我第一次听到这个问题时，项目升级到 Clojure 1.11 后，GitHub Action 失败了。

[edit] 确定 `clj -Sforce -M:check` 返回相同的错误。 以及 `clj -X:deps tree :aliases '[:check]'` 的输出

clj-check 会无条件加载可能已经加载过的代码，这可能导致这种行为。可能切换 clojure 版本会改变加载顺序。

理想情况下，clj-check 应该使用 require 而不是 load（因为它已经从命名空间开始），以避免任何类型的重复加载。

Fastmath 进行了一些操作（https://github.com/generateme/fastmath/blob/master/src/fastmath/core.clj#L1364），这会使它对重复加载非常敏感。

由
我注意到在 fastmath 中的 `vars-to-exclude` 不包括 `abs`，而 `abs` 现在在 1.11 版本的 clojure.core 中已存在。
