COPR fedoraproject.org 构建器拒绝下载我的 .spec 文件中指定的源

Question

我在https://copr.fedoraproject.org 中有一个包构建。我的spec for rpkg is here。构建失败并出现以下问题

Generated rpkg config:
[rpkg]
preprocess_spec = True

[git]
anon_clone_url = https://github.com/%(repo_path)s

[lookaside]
download_url = https://${git_props:remote_netloc}/repo/pkgs/%(repo_path)s/%(filename)s/%(hashtype)s/%(hash)s/%(filename)s

在我的机器上，运行rpkg srpm 成功。

我四处搜索，在我看来，如果 COPR 是通过 https 分发的，那么 COPR 应该愿意下载源代码，我的就是这样。

我可以以某种方式对我的源使用后备缓存功能吗？

Answer 1

通常，通过 https 下载 qpid-proton 文件可以在 Copr 中工作。如果在某处的 rpm 宏中定义了%_disable_source_fetch 0，则它由 rpmbuild（由 rpkg 调用）完成。

问题是spec file 中的一行是：%undefine _disable_source_fetch，它会为给定的规范文件禁用此行为。

Answer 2

您的构建在git_dir_pack 上失败（rpkg-util，又名rpkg 失败）。这发生在rpmbuild 进程甚至开始之前。

A few weeks ago 我们将 Copr 构建器迁移到 Fedora 35， 因此也适用于 rpkg-util v3。随意看看how to fix similar issues。 或者联系rpkg-util upstream 寻求指导。

Answer 3

问题是源文件显然必须从后备缓存中下载。所以，让我们自己创造一个。或者至少，外貌之一。

首先，将所需的源存档下载到您的计算机，到 git repo checkout 目录，然后使用 rpkg 进行“离线上传”

wget https://www.apache.org/dist/qpid/proton/0.37.0/qpid-proton-0.37.0.tar.gz
rpkg upload --offline qpid-proton-0.37.0.tar.gz

这将创建 sources 文件。将其提交给回购。撤消对.gitignore 的编辑，这也是这样做的。 （如果该 rpkg 命令失败，只要创建了 sources 文件，就忽略它。）

使用以下内容创建新文件rpkg.conf，并将其提交到 repo。

[lookaside]
download_url = https://www.apache.org/dist/qpid/proton/0.37.0/%(filename)s

现在推动它并在 COPR 中构建它。

（不要对下面打印的明显错误的download_url 感到困惑；我们在 repo 目录中的rpkg.conf 覆盖了它。）
