我正在使用otj-pg-embedded对一个嵌入式postgres数据库运行一些测试。虽然这些测试在本地运行良好,但在Gitlab-CI运行时失败,出现非法状态异常。GitlabCI构建了它,并运行了不包含otj-pg-embedded的测试。
我已经注解掉了测试类的大部分内容,并将问题定位到:

public static SingleInstancePostgresRule pg = EmbeddedPostgresRules.singleInstance();
import com.goldfinger.models.AuditLog;
import com.opentable.db.postgres.embedded.FlywayPreparer;
import com.opentable.db.postgres.junit.EmbeddedPostgresRules;
import com.opentable.db.postgres.junit.PreparedDbRule;
import org.junit.*;
import org.junit.runner.RunWith;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
public class SQLAuditRepositoryTest {

    private static SQLAuditRepository sqlAuditRepository;
    private static AuditLog auditLog_1;
    private static AuditLog auditLog_2;
    private static AuditLog auditLog_3;
    private static List<AuditLog> auditLogList;

    @ClassRule
        public static SingleInstancePostgresRule pg = EmbeddedPostgresRules.singleInstance();

    @Test
    public void simpleTest() {
        assert (2 == 2);
    }
}

这是堆栈跟踪:

java.lang.IllegalStateException: Process [/tmp/embedded-pg/PG-06e3a92a2edb6ddd6dbdf5602d0252ca/bin/initdb, -A, trust, -U, postgres, -D, /tmp/epg6584640257265165384, -E, UTF-8] failed

这是一个gitlab-ci.yml

image: java:latest
services:
  - postgres:latest
before_script:
  - export GRADLE_USER_HOME=`pwd`/.gradle

package:
  stage: build

任何帮助都将不胜感激。

如果升级到macOS 11.x+(升级到BigSur)后停止

对于Mac用户(特别是新的BigSur),已经有一个issue可以解决这个问题。
目前还没有一个明确的“修复”,但我已经通过安装postgresql的工作:

brew install postgresql

不确定是否同样适用于其他操作系统。

我在MacOS M1上运行嵌入式postgres测试时遇到过类似的问题:

java.lang.IllegalStateException: Process [/var/folders/g_/jxzv9glj0p13njlzpr9xtcfm0000gn/T/embedded-pg/PG-4f38c8a8b2500189835f8ec1b75de81b/bin/initdb, -A, trust, -U, postgres, -D, /var/folders/g_/jxzv9glj0p13njlzpr9xtcfm0000gn/T/pg-embedded-009358be-3e95-4dbe-aa7a-01a9008511cb-3277843270072134584/epg524445573999525527, -E, UTF-8] failed

我复制粘贴命令并在shell上运行它:

/var/folders/g_/jxzv9glj0p13njlzpr9xtcfm0000gn/T/embedded-pg/PG-4f38c8a8b2500189835f8ec1b75de81b/bin/initdb -A trust -U postgres -D /var/folders/g_/jxzv9glj0p13njlzpr9xtcfm0000gn/T/pg-embedded-009358be-3e95-4dbe-aa7a-01a9008511cb-3277843270072134584/epg524445573999525527 -E UTF-8

输出显示了一个提示:

Running bootstrap script ... 2021-02-17 08:18:21.008 WET [28692] FATAL:  could not create shared memory segment: Cannot allocate memory
2021-02-17 08:18:21.008 WET [28692] DETAIL:  Failed system call was shmget(key=5432001, size=56, 03600).
2021-02-17 08:18:21.008 WET [28692] HINT:  This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMALL parameter.  You might need to reconfigure the kernel with larger SHMALL.
    The PostgreSQL documentation contains more information about shared memory configuration.

然后我在贝壳上运行:

sudo sysctl kern.sysv.shmmax=104857600
sudo sysctl kern.sysv.shmall=25600

而且奏效了。

在macOS 12.1 Monterey中,我通过下载postgres二进制文件并让EmbeddedPostgres来解决这些问题,如我在这里所述

# download binaries, here for postgres 12.9
curl -O http://get.enterprisedb.com/postgresql/postgresql-12.9-1-osx-binaries.zip --output-dir /tmp/

# unzip it in /tmp/
unzip /tmp/postgresql-12.9-1-osx-binaries.zip -d /tmp/postgresql-12.9-1-osx-binaries/

然后在代码中:

import com.opentable.db.postgres.embedded.EmbeddedPostgres;
import java.io.File;

EmbeddedPostgres pg = EmbeddedPostgres
  .builder()
  .setPgDirectoryResolver(
     dir -> new File("/tmp/postgresql-12.9-1-osx-binaries/pgsql/"))
  .start();

我在flyway/embedded-pg上遇到过同样的问题。看起来临时文件在某个时候损坏了。重新启动会修复它(直到它再次发生)或者你可以删除/tmp/embedded-pg/目录中的PG-*

Windows用户可能会遇到类似的问题。我的情况是当尝试运行嵌入式postgres的集成测试时:
java.lang.IllegalStateException:进程[C:\用户...\应用程序数据\本地\临时\嵌入式页面\PG-02224 a4 f280160581 d2144 dec 70 deaf 8\bin\initdb.exe,-A,信任,-U,postgres,-D,C:\用户...\应用程序数据\本地\临时\epg 7146074401943849308,-E,UTF-8]失败
当尝试从终端运行此命令时,您将遇到类似以下的dll库问题:
加载共享库时出错:msvcr120.dll:无法打开共享目标文件:没有这样的文件或目录
要解决此问题,应安装Visual C++可再发行包for Visual Studio 2013。您可以从官方microsoft site中找到它
