INTERNAL ERROR: Package database is not sorted!!!

[andywolk]

reprepro multiple-versions-debian branch.
I started seeing The lock file './db/lockfile' already exists. There might be another instance with the error same database dir running. To avoid locking overhead, only one process but there is no other reprepro running at the same time.
This is what I found in the logs. Note
reprepro: archallflood.c:310: save_package_version: Assertion `false' failed.

Thanks for providing the config and db files. I can reproduce the issue with the given files. I wrote a small Python script to check order in the package database:

#!/usr/bin/python3

import apt_pkg
import bsddb3

subtables = [x.decode() for x in bsddb3.btopen("db/packagenames.db", "r").keys()]

for subtable in subtables:
    print("Processing db/packagenames.db '%s'..." % (subtable))

    db = bsddb3.db.DB()
    db.open("db/packagenames.db", subtable, bsddb3.db.DB_BTREE, bsddb3.db.DB_RDONLY)
    print(
        "%s has %i packages and %i package versions"
        % (subtable, len(set(db.keys())), len(db.values()))
    )

    prev_package = ""
    prev_version = ""

    for key, value in db.items():
        key = key.decode().strip("\0")
        value = value.decode().strip("\0")

        package, version = value.split("|")

        if key != package:
            print("Package name differs for key and value: '%s' mistmatches '%s'." % (key, value))

        if package == prev_package:
            # Check order of values
            if apt_pkg.version_compare(version, prev_version) < 0:
                print(
                    "Package version order is wrong for '%s': %s < %s"
                    % (package, version, prev_version)
                )

for subtable in subtables:
    print("Processing db/packages.db '%s'..." % (subtable))

    db = bsddb3.db.DB()
    db.open("db/packages.db", subtable, bsddb3.db.DB_BTREE, bsddb3.db.DB_RDONLY)

    prev_package = ""
    prev_version = ""

    for key in db.keys():
        key = key.decode().strip("\0")

        package, version = key.split("|")

        if package == prev_package:
            # Check order of values
            if apt_pkg.version_compare(version, prev_version) < 0:
                print(
                    "Package version order is wrong for '%s': %s < %s"
                    % (package, version, prev_version)
                )

But this script does not find any incorrect order.

reprepro flood buster started failing too.
