Wipe and reconstruct the instances' mods/ folder using the configured
ModPack for the case were the mods folder is shared with the master
server. This assumes the master server will check the mod checksums
before sending the start request.
Enforce the filename of uploaded mods match {name}_{version}.zip with
name and version taken from the zip file's info.json entry. This allows
it to be used as a unique key for the mod and solves part of the issues
with mods having different number of leading zeros in their version.
The Factorio Mod Portal uses and provides SHA1 hashes of mods, so it
makes sense to align the ModPack and ModInfo structures to sha1 by
renaming the genericly named hash property to sha1.
Add ModPack data type with corresponding storage on the master, messages
to create, update and delete them, as well as commands to invoke them.
The ModPack data type contains a list of mods with versions and optional
sha1 hashes, and mod settings to be used.
Add the ability to manage a set of mods to be shared by the master
server to the rest of the cluster. This implements storage, uploads,
downloads, deletetion, and listing details of mods but does not actually
do anything with the stored mods.
Add ability to move or copy saves between instances. For instances on
the same slave the saves are transferred with filesystem operations, for
instances on two different slaves the proxy stream interface is used to
send the save via the master server.
The interface provided by Winston is unusably slow for querying large
logs. Reimplement the log querying with both forwards and backwards
line reading and a simple file based index to skip files which do not
contain any lines matching the filter.
Add the roles and their permissions for the user the control connection
is connected as along with updates when these change. This enables the
web interface to know which permissions it has available to it.
Add optional limit to the number of log records to return in the
log query request to avoid having the web interface instance console
download the entire log for only to show a few hundred lines from it.
To make it possible to query the end of the log instead of just the
start add an order option as well.
The jsonwebtoken accept strings as input for secrets which is
nonsensical from a cryptographic standpoint as the algorithms all
operate on byte sequences. Worse still, strings are encoded into bytes
using UTF-8, which disallows certain sequences of bytes from appearing
and potentially weakening the cryptography.
For legacy reasons the master secret was encoded into base64 _and passed
as a string to jsonwebtoken_. This further weakened the crypto as the
bytes that can appear in base 64 is only 1/4 of the 256 possible values
for bytes. This could significantly weaken the cryptographic strength
of the tokens.
I have known of this issue for quite some time but has put off actually
fixing it for too long now. Since the master secret is already
documented as being in base 64, decode it as base 64 and pass it as a
byte Buffer to jsonwebtoken. This will ensure every byte value is
possible in the byte sequence passed to the jsonwebtoken crypto.
The impact of this change is unfortunately that all tokens will become
invalid and will have to be reissued.
Add a generate slave token button to the web interface and modify the
generateSlaveToken message and corresponding ctl command to have the
slave id be optional. The random id is the desired behavior when adding
a slave with the installer, as it'll ask for the token for the new slave
and deduce the id from the token.
Add link messages for listing saves and listening for changes to the
list of saves for instances along with a table in the instance view page
showing the save list for the instance and a list-saves command to ctl.
Provide the control link with the ability to subscribe to updates when
instance status and properties changes. This allows the web interface
to respond in real time to instance starts and stops that are triggered
from somewhere else.
