[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

by Galder Zamarreño (JIRA)

Add ability to retrieve cache names remotely in Hot Rod ------------------------------------------------------- Key: ISPN-984 URL: https://issues.jboss.org/browse/ISPN-984 Project: Infinispan Issue Type: Feature Request Components: Cache Server Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 5.0.0.Final A new operation would be needed to retrieve all cache names that are configured and running. A new version of the protocol would need to be set up to deal with the new operation. -- This message is automatically generated by 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] (ISPN-1808) Make InfiniSpan passivation faster

by Johann Burkard (JIRA)

Johann Burkard created ISPN-1808: ------------------------------------ Summary: Make InfiniSpan passivation faster Key: ISPN-1808 URL: https://issues.jboss.org/browse/ISPN-1808 Project: Infinispan Issue Type: Enhancement Components: Loaders and Stores, Marshalling Affects Versions: 5.1.0.FINAL, 5.1.0.CR4 Reporter: Johann Burkard Assignee: Galder Zamarreño While InfiniSpan is very fast in-memory, once passivation is turned on, things get slow for me. On my i5-2400 with a Crucial C300 SSD, it takes about 11 ms to passivate a 2964 B value. This comes down to a write speed of 250 to 300 KB/s. The disk can write up to 180 MB/s so it's not the bottleneck. Clearly, passivation should be faster than that. Profiling with YourKit shows most of the hot spots are centered around {{FileCacheStore}}, the JBoss Marshalling library and various bucket and {{ImmortalCacheEntry}} methods. Locking also seems to play a role. Here's a screenshot: !http://i.imgur.com/LzkPw.png! To make profiling easier for you, I've taken my test case and turned it into a small Maven project. Simply running {{mvn install}} should run the test, ready for profiling. Of course, it could also be that my configuration is suboptimal. However, in my experiments, many configurations were unusable (hitting the file handle limit), which is not a good thing. The project is available at http://johannburkard.de/resources/Johann/infinispan-performance.zip I've also found one or two other things I think are more costly than they would need to be In {{FileCacheStore}} {code} byte[] buffer = new byte[streamBufferSize]; ... fileInStream = new FileInputStream(file); ... bis = new BufferedInputStream(fileInStream); ... bytesRead = bis.read(buffer, 0, streamBufferSize); {code} wrapping the {{FileInputStream}} in a {{BufferedInputStream}} is unnecessary because you already have a buffer in {{byte[] buffer}}. I think I have seen this before in InfiniSpan, so you might want to check for occurrences of {{BufferedInputStream}} or {{BufferedOutputStream}}. Another one {code} if (bytes.length == 0) { // Short circuit if (f.exists()) f.delete(); return; } {code} {{f.exists()}} is essentially a syscall. Just calling {{f.delete()}} is enough. {code} if (!root.exists()) { if (!root.mkdirs()) { log.problemsCreatingDirectory(root); } } if (!root.exists()) { throw new ConfigurationException("Directory " + root.getAbsolutePath() + " does not exist and cannot be created!"); } {code} This could also be shortened to {code} if (!root.mkdirs()) { throw new ConfigurationException("Directory " + root.getAbsolutePath() + " does not exist and cannot be created!"); } {code} -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1001) Should handle 3-way (or more) merges

by Manik Surtani (JIRA)

Should handle 3-way (or more) merges ------------------------------------ Key: ISPN-1001 URL: https://issues.jboss.org/browse/ISPN-1001 Project: Infinispan Issue Type: Feature Request Components: Distributed Cache Affects Versions: 4.2.0.Final Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.0.0.BETA2, 5.0.0.FINAL The current fix for handling merge views (ISPN-923) only handles to 2-way merges reliably.
