SVN提交后名称解析暂时性故障 [英] svn post-commit Temporary failure in name resolution

问题描述

首先，我SVN配置通过Apache DAV可访问。

然后，我有一个post-commit钩子，告诉詹金斯资源库已通过一个简单的wget命令更改持续集成服务器（并使其建立）：

 的/ opt / local / bin目录/ wget的（多选项）的https：//jenkins.domain.tld/subversion/$ {} UUID / notifyCommit转= $ REV＆GT; ＆GT; $ LOGFILE
 

脚本检查wget的收益code，然后回声一个错误信息并退出1（所以svn客户端知道提交失败）。

日志文件包含了故障后：

   -  2012-04-04 10：56：54-- HTTPS：//jenkins.domain.tld/subversion/4d729FFF-FFFF-4fb8-b8b5-be083cf6fe96/notifyCommit？ REV = 302
分辨率德jenkins.domain.tld（jenkins.domain.tld）...échec：名称解析暂时性故障。
wget的：不可能去résoudreL'住址DE L'套餐«jenkins.domain.tld»
 

主机 jenkins.domain.tld 已被添加到 / etc / hosts中，以确保该决议能够T失败，但我仍然有问题。

当然，我已经检查从CLI中提交后命令，和它的作品。

我添加此行后提交脚本：

 的/ usr / bin中/主机jenkins.domain.tld＆GT;＆GT; $ LOGFILE
 

和解析工作就好了... ...也许wget的问题。

刚刚更换的wget调用使用卷曲相当，同样的问题：

 卷曲：（6）无法解析主机'jenkins.domain.tld
 

解决方案

好吧，没有找到问题的起源，而是一个解决方案（pretty丑）：

  

更新：我解决它同时充分停止Apache，等待片刻，然后再次启动。但是，这并不能说明根本原因这种行为（因此没有令人满意的解决方案）。所以我离开这个开放的。

First, I have svn configured to be accessible via apache DAV.

Then I have a post-commit hook that tell jenkins continuous integration server that the repository has changed via a simple wget command (and make it build) :

/opt/local/bin/wget (many-options) https://jenkins.domain.tld/subversion/${UUID}/notifyCommit?rev=$REV >> $LOGFILE

The script checks wget return code, and then echos an error message and exit with 1 (so the svn client knows the commit failed).

The LOGFILE contains after a failure :

--2012-04-04 10:56:54--  https://jenkins.domain.tld/subversion/4d729FFF-FFFF-4fb8-b8b5-be083cf6fe96/notifyCommit?rev=302
Résolution de jenkins.domain.tld (jenkins.domain.tld)... échec: Temporary failure in name resolution.
wget : impossible de résoudre l'adresse de l'hôte «jenkins.domain.tld»

The host jenkins.domain.tld has been added to /etc/hosts to be sure that resolution can't fail, but I'm still having the issue.

Of course, I have checked the post-commit command from CLI, and it works.

I've added this line to the post-commit script :

/usr/bin/host jenkins.domain.tld >> $LOGFILE

And resolution works just fine... maybe a wget issue.

Just replaced wget call with a curl equivalent, same issue :

curl: (6) Couldn't resolve host 'jenkins.domain.tld'

解决方案

Ok, not found the issue origin, but a solution (pretty ugly) :

Update: I solved it meanwhile by fully stopping apache, waiting for a moment, then starting it again. But that doesn't explain the root cause for this behaviour (and thus there's no satisfying solution). So I leave this open.
