Question

我正在使用otj-pg-embedded对嵌入式postgres数据库进行一些测试。尽管这些测试在本地运行良好，但是当由Gitlab-CI运行并带有非法状态异常时失败。 Gitlab CI可以构建它并运行不包含otj-pg嵌入式的测试。

我已经注释掉了大多数测试类，并指出了问题所在：

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gitlab-ci.yml

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

package:
  stage: build
  script:
    - ./gradlew assemble

test:
  stage: test
  script:
  - ./gradlew check

    reports:

任何帮助将不胜感激。

我在 MacOS M1 上使用嵌入式 postgres 运行测试时遇到了类似的问题：

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

我复制粘贴的命令并在 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

并且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.

initdb: removing contents of data directory "/var/folders/g_/jxzv9glj0p13njlzpr9xtcfm0000gn/T/pg-embedded-cbe6f5f8-24b2-4431-afec-6e7aeb1dbb5d-8656684715588054403/epg6904898061245880853"

然后我在 shell 上运行：

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

它奏效了。

Answer 2

对于Mac用户（尤其是新的BigSur），已经有一个issue可以解决此问题。

还没有一个确定的“修复程序”，但是我可以通过以下方式安装postgresql：

brew install postgresql

不确定是否同样适用于其他操作系统。

Answer 3

我在flyway / embedded-pg中遇到了同样的问题。似乎临时文件在某个时刻已损坏。重新启动将修复它（直到再次发生），或者您可以删除PG-*内的/tmp/embedded-pg/目录

使用嵌入式postgres的测试因非法状态异常而失败
