[JBoss JIRA] Created: (ISPN-907) SSL access to Hot Rod

by Galder Zamarreño (JIRA)

SSL access to Hot Rod --------------------- Key: ISPN-907 URL: https://issues.jboss.org/browse/ISPN-907 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 5.0.0.BETA1, 5.0.0.Final Investigate and integrate Adrian's patch for Hot Rod server so that it can accessed via SSL. Email from Adrian: "While I remember heres a patch to add ssl for infinispan clients. I did it a couple of weeks ago, but I dont know when Ill have time to finish it off/polish it. It was based on head a few weeks ago, but I dont remember which version. :-( The horrible part is the way I had to modify all the parameter lists. It could really do with passing some config object instead. I dont know how to make "git diff" include new uncommitted files so Ive attached them seperately. See the test for how to use it, but it is basically set the config properties (with the relevant infinispan package prefixes) use_ssl=true key_store_file_name=jks file containing our key key_store_password=secret trust_store_file_name=jks file containing public keys we trust for authentication trust_store_password=another-secret Optionally you can get the server to authenticate the client as well need_client_auth=true which means the server will need a trust store. I've also left it so if you dont set the properties it will use the default implementations. But this doesnt work out of the box unless you enable the "anon" alogorithms on the server, they aren't enabled by default. Those dont authenticate, they just encrypt the traffic. The main thing left to do would be change the test to get maven to generate the key/trust store in a well defined place in "target". Other comments: * The code on the serrver will also work for other protocols as well, e.g. memcached if the client supports ssl * The ssl context construction is pretty similar in the client/server and could probably be shared if I knew where to put shared stuff in the codebase. :-) * There is some commented out bits where I think the client/server should really be adding socket timeouts. Otherwise network drops/splits could cause the connection to hang forever. There should at least be a connection timeout on the socket construction, if you dont want to implement a full blown ping to continually test the connection rather than just ping on start - which doesnt run until after the connection timeout is needed. * I had to modify the system property handling so you can have a default of "null". I only did this for Strings, might not be relevant for others? * Why doesnt the client side do system property replacement like the server? * Theres a lot of places in the code doing InputStream is = openStream(); useIt(is); but never close the stream. While this is probably ok in infinispans use cases it is not good practice to leave files open for the gc to close - that could take a while to happen and you are hogging system resources. Either useIt() should close the stream or the code should be InputStream is = openStream(); try { useIt(is); } finally { is.close(); } Feel free to post whatever parts of this message you like in the infinispan forum. :-)" -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-820) Resolve {@link} links in configuration reference

by Galder Zamarreño (JIRA)

Resolve {@link} links in configuration reference ------------------------------------------------- Key: ISPN-820 URL: https://jira.jboss.org/browse/ISPN-820 Project: Infinispan Issue Type: Feature Request Reporter: Galder Zamarreño Assignee: Vladimir Blagojevic Fix For: 5.0.0.BETA1 Currently configuration reference documentation does not resolve {@link} links. It'd be nice if it'd point to the javadoc of the corresponding class if available! Examples: - Fully qualified class name of a class that looks up a reference to a {@link javax.transaction.TransactionManager}. The default provided is capable of locating the default TransactionManager in most popular Java EE systems, using a JNDI lookup. (Javadoc) - Fully qualified name of the class that the configured {@link org.infinispan.marshall.Externalizer} can marshall/unmarshall. Establishing the link between type marshalled and {@link org.infinispan.marshall.Externalizer} implementations enables users to provide their own marshalling mechanisms even for classes which they cannot modify or extend.

[JBoss JIRA] Created: (ISPN-767) Make deadlock detection run over multiple caches

by Mircea Markus (JIRA)

Make deadlock detection run over multiple caches ------------------------------------------------ Key: ISPN-767 URL: https://jira.jboss.org/browse/ISPN-767 Project: Infinispan Issue Type: Feature Request Reporter: Mircea Markus Assignee: Manik Surtani Fix For: 5.2.0.Final right now deadlock detection runs on a per cache basis. Eg. following deadlock won't be detected: - N1,N2 two nodes, A and B are cache running on each of them. tx1 running on N1: N1.A.put(k1); N1.B.put(k2) tx2 running in N2: N2.B.put(k2); N2.A.put(k1) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-924) Support Atomic arithmetic operations in the API

by Erik Salter (JIRA)

Support Atomic arithmetic operations in the API ----------------------------------------------- Key: ISPN-924 URL: https://issues.jboss.org/browse/ISPN-924 Project: Infinispan Issue Type: Feature Request Reporter: Erik Salter Assignee: Manik Surtani It would be useful if Infinispan supported cluster-wide atomic operations for java.lang.Number types in the API -- similar to the AtomicX API in Java. Right now, to cobble this functionality, we'd need to do something like: - Start a tx - Single-lock a key - Get and increment - Commit - And, of course, handle the cache exceptions =) -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-445) Ensure that locks time out

by Phil vd (JIRA)

Ensure that locks time out -------------------------- Key: ISPN-445 URL: https://jira.jboss.org/browse/ISPN-445 Project: Infinispan Issue Type: Feature Request Components: Locking and Concurrency Reporter: Phil vd Assignee: Manik Surtani When a lock is acquired, no mechanism ensure that it is reclaimed later. So if for whatever reason the thread owning the lock is stuck in an endless loop or waiting for some resource, the entry is locked. This kind of situation could happen in cache stores trying to contact a remote storage. The risk is quite high that other entries may be locked as well if you use lock stripping (default : TRUE) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-627) Provision to get Cache from CacheManager, without starting the Cache

by Girish Adat (JIRA)

Provision to get Cache from CacheManager, without starting the Cache -------------------------------------------------------------------- Key: ISPN-627 URL: https://jira.jboss.org/browse/ISPN-627 Project: Infinispan Issue Type: Feature Request Components: Core API Affects Versions: 4.0.0.Final Reporter: Girish Adat Assignee: Manik Surtani Provision to getCache() from CacheManager, without starting the cache. This is for achieving scenarios like adding cache-listeners before starting the cache for first time. Adding a method getCache(String cacheName, boolean start) will work for the requirement. Also, any change in cache level configuration can be made programmatically by the client application, if this method is implemented. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-755) Provide API documentation for scala components within the distribution

by Richard Achmatowicz (JIRA)

Provide API documentation for scala components within the distribution ---------------------------------------------------------------------- Key: ISPN-755 URL: https://jira.jboss.org/browse/ISPN-755 Project: Infinispan Issue Type: Feature Request Affects Versions: 4.1.0.Final Reporter: Richard Achmatowicz Assignee: Manik Surtani Infinispan makes use of the Scala language to implement server modules for client-server communication. At present, these modules do not have any API documentation, which means that application developers must browse through the source code in order to find out which classes are available and what their interfaces are. Scala has the ability to produce scaladoc documentation, but this is not compatible with javadoc. It appears that there is no method at present to incorporate scala API information into existing javadoc documentation. The task of this issue is to investigate and implement a viable way to incorporate API information for the scala classes into the Infinispan distribution. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-604) Re-design CacheStore transactions

by Mircea Markus (JIRA)

Re-design CacheStore transactions ---------------------------------- Key: ISPN-604 URL: https://jira.jboss.org/browse/ISPN-604 Project: Infinispan Issue Type: Feature Request Components: Loaders and Stores, Transactions Affects Versions: 4.1.0.CR2, 4.0.0.Final Reporter: Mircea Markus Assignee: Mircea Markus Fix For: 5.0.0.Final Current(4.1.x) transaction implementation in CacheStores is brocken in several ways: 1st problem. - AbstractCacheStore.prepare: public void prepare(List<? extends Modification> mods, GlobalTransaction tx, boolean isOnePhase) throws CacheLoaderException { if (isOnePhase) { applyModifications(mods); } else { transactions.put(tx, mods); } } If this is 1PC we apply the modifications in the prepare phase - we should do it in the commit phase (as JTA does it). 2nd problem. This currently exhibits during commit/rollback with JdbcXyzCacheStore, but it is rather a more general cache store issue. When using a TransactionManager, during TM.commit AbstractCacheStore.commit is being called internally which tries to apply all the modifications that happened during that transaction. Within the scope of AbstractCacheStore.commit, JdbcStore obtains a connection from a DataSource and tries to write the modifications on that connection. Now if the DataSource is managed (e.g. by an A.S.) on the DS.getConnection call the A.S. would try to enlist the connection with the ongoing transaction by calling Transaction.enlistResource(XAResource xaRes) [1] This method fails with an IllegalStateException, because the transaction's status is preparing (see javax.transaction.Transaction.enlistResource). Suggested fix: - the modifications should be registered to the transaction as they happen(vs. during prepare/commit as it happens now) - this requires API changes in CacheStore, e.g. void store(InternalCacheEntry entry) should become void store(InternalCacheEntry entry, GlobalTransaction gtx) (gtx would be null if this is not a transactional call). [1] This behavior is specified by the JDBC 2.0 Standard Extension API, chapter 7 - distributed transaction -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
