Breaking change between version 2.0.1 and version 2.0.2

When the FilteredAdapter interface was implemented (#25), another unrelated change was introduced. Unfortunately, this was a breaking change.

In particular, the CasbinRule format changed, a new field was added:

int id; //Fields reserved for compatibility with other adapters, and the primary key is automatically incremented.

Now, this is fine on its own since the implementation completely ignores it, but the expected casbin_rule table structure changes accordingly.

Since the query is as follows:

SELECT * FROM casbin_rule;

The id column is expected to be the first column and is implicitly skipped:

            while (rSet.next()) {
                CasbinRule line = new CasbinRule();
                for (int i = 1; i <= rData.getColumnCount(); i++) {
                    if (i == 2) {
                        line.ptype = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 3) {
                        line.v0 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 4) {
                        line.v1 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 5) {
                        line.v2 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 6) {
                        line.v3 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 7) {
                        line.v4 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    } else if (i == 8) {
                        line.v5 = rSet.getObject(i) == null ? "" : (String) rSet.getObject(i);
                    }
                }
                loadPolicyLine(line, model);
            }

However, this is breaking existing applications that have been using this Adapter from before version 2.0.2, since the casbin_rule table doesn't include the id column.

On the top of my head, I can think of 2 alternatives to resolve this:

You could rewrite the query to be:

SELECT ptype, v0, v1, v2, v3, v4, v5 FROM casbin_rule;

and you would shift the conditions on i back to start at 1.

Instead of using column indexes, you could use column names:

line.ptype = rSet.getObject("ptype") == null ? "" : (String) rSet.getObject("ptype");

maven central repository jar package missing

The jar package in maven central for 1.1.2 is missing.
https://repo.maven.apache.org/maven2/org/casbin/jdbc-adapter/

If you write the pom dependency as in the readme file, the project doesn't compile.

Broken connection not re-established.

I've got a jcasbin setup with a JDBC adapter connecting to postgres. Both the jcasbin setup and the postgres are running as containers in separate Kubernetes pods.
If the Postgres pod goes down and is restarted, the next call from the adapter fails with:

java.sql.BatchUpdateException: Batch entry 0 INSERT INTO casbin_rule (ptype,v0,v1,v2,v3,v4,v5) VALUES(*[SNIP]*) was aborted: An I/O error occurred while sending to the backend.  Call getNextException to see other errors in the batch.

After restarting the casbin setup, everything works as expected again. Could the error handling be changed so that the adapter attempts to reconnect in case of a closed connection, instead of immediately having an unrecoverable state?

Potential for partial/complete dataloss

Failure in the savePolicy function can lead to a complete loss of all data because savePolicy doesn't use transactions AND:

First drops the table
Recreates the table.
Executes a batch of inserts to save the policy.

If 1 succeed and a failure occurs anytime after it can lead to a partial or complete data loss.

It'd be much safer if it:

Started a transaction
Deleted everything in the table (not drop table, mysql doesn't support DML transactions)
Inserted the new policy.
Committed the transaction.

I actually don't see any usage of transactions in this Adapter, which is worrisome, but maybe I'm missing something?

2.0.2 not loading old data with jcasbin >1.10.2

Can we get a new release which includes #33 ?

Context:
Before jcasbin 1.10.2, the following code would load all policies currently stored in the DB:

this.jdbcAdapter = new JDBCAdapter(this.dataSourceFactory.createDataSource(props));
final Model model = CoreEnforcer.newModel(this.getResourceFileAsString("rbac_model.conf"));
this.enforcer = new Enforcer(model, this.jdbcAdapter);

With jcasbin 1.10.2 and up, existing policies are no longer loaded. This seems to be because of the isFiltered check introduced in casbin/jcasbin@c61a1ab . #33 sets the default value for isFiltered to false, which I assume will fix the issue.

Support FilteredAdapter interface

See details at: https://github.com/casbin/jcasbin/search?q=FilteredAdapter

This is a customer requirement from our Gitter: https://gitter.im/casbin/Lobby

Takes 2 hrs to load 4L Policy records

I have been trying the JDBC adapter for jcasbin. While trying to insert approx 4L records for policy it took more than 2 hours
The code that I used was as follows

public static void main(String[] a) throws Exception {

JDBCAdapter a1 = new JDBCAdapter(driver, url, username, password);
Enforcer e = new Enforcer("C:\\temp\\jcasbin_try\\model.conf", a1);

long start = System.currentTimeMillis();
System.out.println("Starting at " + new Date());
for (int object = 101; object <= 20000; object++) {
	for (int identity = 1; identity <= 20; identity++) {
		e.addPolicy("rdt00"+identity, "PlannerObject_"+object, "read");
	}
}
long end = System.currentTimeMillis();
System.out.println("Ending addPolicy at " + new Date() + " total Time : " + (end - start));

e.savePolicy();
System.out.println("Ending savePolicy at " + new Date() + " total Time : " + (System.currentTimeMillis() - end));
}

`casbin_sequence` is generated even when `casbin_rule` table is made beforehand using `GenerationType.IDENTITY`

I implicitly created casbin_rule table with Id generation type as IDENTITY. But it created casbin_sequence which wasn't required and happened because of
case "PostgreSQL": sql = renderActualSql("CREATE SEQUENCE IF NOT EXISTS CASBIN_SEQUENCE START 1;");

in JDBCBaseAdapter.java .
It should only be executed when the table doesn't exist otherwise the generation of sequence is redundant.

Question: Table structure for storing policy in database.

Hi,
I need to store my policy in database. I will be using postgresql.
So do I need to have a specific table structure or It can be custom?

For example I want to store this policy

p, nsm_role, /national_sales, *
p, rsm_role, /regional_sales, *
p, asm_role, /area_sales, *


g, nsm_role, rsm_role
g, rsm_role, asm_role

g, nsm_user, nsm_role
g, nsm_user, admin_role
g, rsm_user, rsm_role
g, asm_user, asm_role

From seeing the codebase it seems there should be columns like p_type, v1, v2, v3 etc.
But what does this mean, can you explain please?

Can I have multiple tables like user_roles_table for g mapping and policy_table for p mapping?

Thanks

Transaction not closed and database locks not released

Description

When using jdbc-adapter v2.2.0 or v2.2.1 with PostgreSQL, the database connection is easy to stuck in "idle in transaction" status: the transaction is not closed and locks also not released.

Especially when deploying multiple instances using redis-watcher, other instances' operation is likely to fail due to cannot get database lock.

To Reproduce

Create enforcer with JDBCAdapter and RedisWatcher

String modelPath = "path/to/model";
JDBCAdapter adapter = new JDBCAdapter(databaseDriver, databaseUrl, databaseUsername, databasePassword);
SyncedEnforcer enforcer = new SyncedEnforcer(modelPath, adapter);

RedisWatcher watcher = new RedisWatcher(redisHost, redisPort, redisChannel, 5000, redisPassword);
enforcer.setWatcher(watcher);

Call any API that add/remove policies, e.g. enforcer.addNamedPolicy()
Check the database status, the connection is in "idle in transaction" status and holding some locks.

Root Cause

In v2.2.0 and v2.2.1, auto-commit is set to false in method addPolicies and removePolicies, and never set back to ture after the operation is finished.

So, after the policies were modified, the enforcer received update notice from the watcher and calls adapter's loadPolicy method, which will hang the transaction due to auto-commit = false.

Fix

I prepared a fix, please review: #50

feature: JDBCAdapter doesn't implement the UpdatableAdapter interface

What I do:
Calling enforcer.updatePolicy(oldPolicyParams, newPolicyParams); to execute and save policy changes.

What to expect:
Persist policy changes to the database.

What we get:
Policy changes were not persisted to the database.

Requirement:
It is hoped that JDBCAdapter will implement the UpdatableAdapter interface.

What is UpdatableAdapter?

Question/Bug: savePolicy fails with NPE for ACL model

Hello,

I am new to JCasbin, so apolologies if this is a rookie mistake.

Executing this code

String s = """
                # Request definition
                [request_definition]
                r = sub, obj, act
                                
                # Policy definition
                [policy_definition]
                p = sub, obj, act
                                
                # Policy effect
                [policy_effect]
                e = some(where (p.eft == allow))
                                
                # Matchers
                [matchers]
                m = r.sub == p.sub && r.obj == p.obj && r.act == p.act
                """;

Model model = newModel(s);
InitialContext context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup(DB_ALIAS);
Adapter adapter = new JDBCAdapter(dataSource);
Enforcer e = new Enforcer(model, adapter);
e.addPolicy("foo", "bar", "read");
e.savePolicy();

fails with a NPE

The NPE occurs at https://github.com/jcasbin/jdbc-adapter/blob/master/src/main/java/org/casbin/adapter/JDBCBaseAdapter.java#L299
because model.model.get("g") is null.

Shouldn't the code handle the different authorization model types? (the model above is the default ACL model).
Or am I missing something?

Load policies is slow

org.casbin.jcasbin.persist.JDBCBaseAdapter has loadPolicy method to fetch data from db.
Then it iterates over the rows and for each of the row it calls loadPolicyLine -> Helper.loadPolicyLine.

Inside helper there is:

    public static void loadPolicyLine(String line, Model model) {
        if (!"".equals(line)) {
            if (line.charAt(0) != '#') {
                String[] tokens = Util.splitCommaDelimited(line);
                String key = tokens[0];
                String sec = key.substring(0, 1);
                Assertion ast = (Assertion)((Map)model.model.get(sec)).get(key);
                ast.policy.add(Arrays.asList(Arrays.copyOfRange(tokens, 1, tokens.length)));

                for(int i = 0; i < ast.policy.size(); ++i) {
                    ast.policyIndex.put(((List)ast.policy.get(i)).toString(), i);
                }

            }
        }
    }

one more row loop.
so for the db rows it will iterate like this:

1 1 1 ... n
  2 2     2
     3     3
            ...
            n

why do you need this internal for loop?
it can be changed to:

    public static void loadPolicyLine(String line, Model model) {
        if (!"".equals(line)) {
            if (line.charAt(0) != '#') {
                String[] tokens = Util.splitCommaDelimited(line);
                String key = tokens[0];
                String sec = key.substring(0, 1);
                Assertion ast = (Assertion)((Map)model.model.get(sec)).get(key);

                List<String> nPolicy = Arrays.asList(Arrays.copyOfRange(tokens, 1, tokens.length))
                ast.policy.add(nPolicy);
                ast.policyIndex.put(policy.toString(), ast.policy.size() - 1);
            }
        }
    }

so no loop, faster load. what is the reason of it? Or maybe i missed something?

v1.1.2 bug

code: "?rewriteBatchedStatements=true".
It should be like this:

if url.contains("?"){
    url = url + "&rewriteBatchedStatements=true";
}else {

}

Connection is closed

when using DataSource to initialize the JDBC adapter to use Jcasbin, it's OK at first several hours.
However, when it takes long enough, problem happens. It cannot connect to Database, I try to solve the problem according the log hint., I tried:

set spring.datasource.hikari.validationTimeout = 300000 for application
add &autoReconnect=true to jdbcUrl
but it doesn't works at all.

🚨 The automated release from the `master` branch failed. 🚨

I recommend you give this issue a high priority, so other packages depending on you can benefit from your bug fixes and new features again.

You can find below the list of errors reported by semantic-release. Each one of them has to be resolved in order to automatically publish your package. I’m sure you can fix this 💪.

Errors are usually caused by a misconfiguration or an authentication problem. With each error reported below you will find explanation and guidance to help you to resolve it.

If you are not sure how to resolve this, here are some links that can help you:

If those don’t help, or if this issue is reporting something you think isn’t right, you can always ask the humans behind semantic-release.
