Google Go AppEngine在服务/测试时导入并冲突 [英] Google Go AppEngine imports and conflicts when serving / testing
问题描述
- 使用Go和Appengine。我试图
得到适当的单元测试工作时遇到问题。
- 我已经尝试了很多结构，但这里是我现在的样本：https://github.com/markhayden/SampleIssue
- 我正在运行
goapp serve或goapp test -v ./src/lib1，具体取决于我如何设置导入路径。
如果我使用src / lib1作为我的导入路径，然后 goapp serve 。我的应用程序启动并运行正常，但是当我运行测试时，出现以下故障：
src / lib1 / lib1.go： 5：2：在
/ Users / USERNAME / go_appengine / goroot / src / pkg / src / lib2（from $ GOROOT）中找不到软件包src / lib2
/ Users / markhayden / Projects / go / src / src / lib2（from $ GOPATH）
同样，如果我使用dummy / src / lib1作为我的路径，我的测试很开心并且运行良好，但是在 goapp serve 应用程序I现在得到：
2014/11/06 20:33:34 go-app-builder：解析输入失败：app文件lib1 .go与从GOPATH导入的相同文件冲突
已经摆弄各种不同的选项，弄清楚如何处理依赖关系并仍然有坚实的测试。也许它是一个appengine / golang的bug？或者我错过了什么？
任何帮助将非常感激。提前致谢！
根据第一条评论反馈更新了所有内容。我可以运行测试（就像我以前能够做的那样），但我仍然无法为应用程序提供服务。这是我运行 goapp serve

$ GOROOT =没有设置（根据docs，如果你不使用自定义目录，它不需要）
应用程序结构：
$ GOPATH / src / github.com / markhayden / SampleIssue /
- yaml
- / lib1
- lib1_test.go
- lib1.go
- / lib2
- lib2_test.go

）
Appengine与从GOPATH导入的相同文件冲突问题： / h2>
Appengine正在导入根目录下的东西（即app.yaml在哪里）。这将导致两个导入，其中一个在appengine扫描目录时导致，另一个导入时由源导入。
您有两种选择：
不要使用完整的导入路径使用appengine。
-
删除导入的源存储库部分。所以，而不是
github.com/blah/blah这将是blah / blah。
注意：有点吮吸，因为它使你的构建和软件appengine具体。通过使用构建约束，您可以使其更好一些。例如
+ build！appengine或
+ build！appengine包含/删除构建中的某些文件，具体取决于如果你的目标是appengine。
将您的模块/依赖关系（子文件夹）移动到一个独立的独立项目中以使其工作使用完整路径导入约定：
- 摆脱主项目中的所有目录/依赖项（其中
你的app.yaml是），这样appengine就无法扫描并找到它们。 - 将它们移动到另一个独立的项目（我做了SampleIssueDeps）
，没有app.yaml是不是子目录（例如
/ MarkHayden / SampleIssueDeps）。 然后，通过
完整路径导入拉出这些依赖关系。例如github.com/MarkHayden/SampleIssueDeps/lib1。 - 摆脱主项目中的所有目录/依赖项（其中
- Using Go and Appengine. I am running into issues when trying to get proper unit tests working.
- I have tried lots of structures but here is a sample of where I am now: https://github.com/markhayden/SampleIssue
- I am running into dependency issues in either
goapp serveorgoapp test -v ./src/lib1depending on how I have my import paths set.
摘要：对于appengine中的子文件夹包项目不包括导入路径的源存储库部分，或者只使用init（）的appengine并将所有其他代码移动到单独的项目中并使用像外部依赖项。
So I have spent the better part of two days trying to figure this one out and no matter what I do I can't get things straightened out. Here is what is going on:
If I use "src/lib1" for my import path and then goapp serve. My app boots and runs fine, but when I run tests I get the following failure:
src/lib1/lib1.go:5:2: cannot find package "src/lib2" in any of:
/Users/USERNAME/go_appengine/goroot/src/pkg/src/lib2 (from $GOROOT)
/Users/markhayden/Projects/go/src/src/lib2 (from $GOPATH)
Likewise, if I use "dummy/src/lib1" as my path, my tests are happy and run fine but upon goapp serve ing the app I now get:
2014/11/06 20:33:34 go-app-builder: Failed parsing input: app file lib1.go conflicts with same file imported from GOPATH
Have fiddled with all sorts of different options and can't figure out how to handle dependencies and still have solid testing. Maybe its a appengine / golang bug? Or am I missing something?
Any help would be very much appreciated. Thanks in advance!
Updated everything based on first comment feedback. I can run tests (as I was able to do before) but I still can not serve the app. Here is what I get when running goapp serve

2014/11/07 09:24:49 go-app-builder: Failed parsing input: app file lib2.go conflicts with same file imported from GOPATH
$GOPATH = /Users/markhayden/Projects/go
$GOROOT = not set (according to docs it doesnt need to be if you dont use a custom directory)
App Structure:
$GOPATH/src/github.com/markhayden/SampleIssue/
- app.yaml
- /lib1
- lib1_test.go
- lib1.go
- /lib2
- lib2_test.go
- lib2.go
- main_test.go
- main.go
In main.go:
import (
"fmt"
"github.com/markhayden/SampleIssue/lib1"
"net/http"
)
In lib1/lib1.go:
import (
"fmt"
"github.com/markhayden/SampleIssue/lib2"
)
Appengine "conflicts with same file imported from GOPATH" issue:
Appengine is importing things underneath the root directory (i.e. where the app.yaml is). This will cause two imports, one by appengine when it scans the directories, and a second by your source when it is explicitly imported.
You have two choices:
Don't use the full import path (for sub-folder packages) with appengine.
Remove the source repository part of import. So instead of "github.com/blah/blah" it would be "blah/blah".
Note: This kinda sucks as it makes your build and software appengine specific. You could make this a little better -maybe- by using build constraints. e.g.
+build !appengineor+build !appengineto include/remove certain files from the build depending on if you are targeting appengine.
Move your modules/dependencies (sub-folders) to a separate and independent project to make it work with the full path import convention:
- Get rid of all directories / dependencies in the main project (where your app.yaml is), so that appengine can't scan and find them.
- Move them to another independent project (I did SampleIssueDeps) with no app.yaml that is not a sub-directory (e.g. /MarkHayden/SampleIssueDeps).
- Then pull those dependencies via full path import. e.g. github.com/MarkHayden/SampleIssueDeps/lib1.
Summary: For sub-folder packages in an appengine project don't include the "source repository" part of the import path OR only use appengine to init() and move all of your other code to separate projects and use like external dependencies.
