如何在阿尔卑斯山显示错误的细节

Question

我使用阿尔卑斯Linux3.9.3 x86_64

当我发布：

# apk upgrade

产出如下：

3 errors; 1973 MiB in 519 packages

我怎样才能得到关于这三个错误的详细信息？我尝试了--verbose标志，但是结果是一样的。

这些是我认为可行的解决办法：

apk -sv fix

-s (或--simulate)应该在不进行修复的情况下模拟修复，-v (或--verbose)应该显示更多细节，但两者都不起作用。

结果是：

# apk -sv fix
(1/3) Reinstalling fuse-common (3.2.6-r1)
(2/3) Reinstalling fuse-openrc (3.2.6-r1)
(3/3) Reinstalling xorgproto (2018.4-r0)
3 errors; 524 packages, 2845 dirs, 48016 files, 2002 MiB

但仍然没有细节，只是一个简短的总结。我想知道出了什么问题，我找不到任何原木之类的东西。

Answer 1

apk fix

此命令列出并修复错误。

Answer 2

我遇到了同样的问题，并试图阅读源代码，以找出显示错误细节的方法。不幸的是，我认为apk CLI是不可能的。

但是..。

在src/src.c#L 365-L 382中，输出中的数字错误似乎存储在变量errors中。例如，3 errors; 1973 MiB in 519 packages。

    if (errors)
        snprintf(buf, sizeof(buf), "%d error%s;", errors,
             errors > 1 ? "s" : "");
    else
        strcpy(buf, "OK:");
    if (apk_verbosity > 1) {
        apk_message("%s %d packages, %d dirs, %d files, %zu MiB",
                buf,
                db->installed.stats.packages,
                db->installed.stats.dirs,
                db->installed.stats.files,
                db->installed.stats.bytes / (1024 * 1024));
    } else {
        apk_message("%s %zu MiB in %d packages",
                buf,
                db->installed.stats.bytes / (1024 * 1024),
                db->installed.stats.packages);
    }

在src/src.c#L 333-L 352中，当ipkg (指已安装的包)的broken_files或broken_scripts被计算为true时，errors会增加。因此，我们有机会区分这一点。

    r = change->old_pkg &&
        (change->old_pkg->ipkg->broken_files ||
         change->old_pkg->ipkg->broken_script);
    if (print_change(db, change, prog.done.changes, prog.total.changes)) {
        prog.pkg = change->new_pkg;
        progress_cb(&prog, 0);

        if (!(apk_flags & APK_SIMULATE) &&
            ((change->old_pkg != change->new_pkg) ||
             (change->reinstall && pkg_available(db, change->new_pkg)))) {
            r = apk_db_install_pkg(db, change->old_pkg, change->new_pkg,
                           progress_cb, &prog) != 0;
        }
        if (r == 0 && change->new_pkg && change->new_pkg->ipkg)
            change->new_pkg->ipkg->repository_tag = change->new_repository_tag;
    }
    errors += r;

在src/database.c#L 874-L 885中读取代码后，它显示了一个存储已安装包信息的数据库文件，并且它有一个无证字符字段f，该字段表示我们想知道的错误类型。

    case 'f':
        for (r = 0; r < l.len; r++) {
            switch (l.ptr[r]) {
            case 'f': ipkg->broken_files = 1; break;
            case 's': ipkg->broken_script = 1; break;
            case 'x': ipkg->broken_xattr = 1; break;
            default:
                if (!(apk_force & APK_FORCE_OLD_APK))
                    goto old_apk_tools;
            }
        }
        break;
