[jira] Created: (VELOCITY-514) Rendering a template with inline
macro concurrently causes VM error : Null AST
Rendering a template with inline macro concurrently causes VM error : Null AST
------------------------------------------------------------------------------
Key: VELOCITY-514
URL: https://issues.apache.org/jira/browse/VELOCITY-514
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.4
Reporter: Sam Chang
If a template with inline macro is rendered concurrently it prints the following errors in the log:
ERROR [velocity] VM #myInlineMacro: error : too few arguments to macro. Wanted 3 got 0
ERROR [velocity] VM error : myInlineMacro. Null AST
and where the expected output of the inline macro is, it has the string values of the arguments passed to the macro in brackets
eg:
#myInlineMacro('Arg1' 'arg2' 'arg3')
gives the following on above error
(Arg1 arg2 arg3)

-------------------------------------------------
This smells like VELOCITY-24. I'm scared that you claim to be able to reproduce this with beta1 and beta2, because the fix should already be in beta2. I can see nothing in between beta2 and the release that actually fixes this.

Put this on the "need to verify" stack for 1.5.1/1.6. If it is bogus, good. If it is not, fix it in the next release.

Replication of this thread does not require tons of threads fighting each other.
The same thing happens (at least, with 1.4) when you define a recursive macro.

This might be fixed in Velocity 1.5-- we fixed a number of subtle bugs around concurrency and error reporting. There's a beta out, and a full release expected in a couple days. Would you mind downloading the 1.5 beta and see if this issue still exists?

[jira] Updated: (VELOCITY-514) Rendering a template with inline

Posted by "Sam Chang (JIRA)" <de...@velocity.apache.org>.
[ https://issues.apache.org/jira/browse/VELOCITY-514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sam Chang updated VELOCITY-514:
-------------------------------
Attachment: nullAST.log
macroSlammer.jar
Attached macroSlammer.jar which reproduces the errors by queuing up multiple threads to render from a velocity template file.
Also attached nullAST.log with the errors
Requirements:
Java 1.5
Multiple CPU's
To run:
java -jar macroSlammer.jar
This will create velocity.log which contains the error. You may need to run it several times to reproduce.
(I found it to be reproduceable atleast 1 in 2 tries)

Norbert Pomaroli commented on VELOCITY-514:
-------------------------------------------
We also can reproduce this bug with both velocity-1.4 and velocity-1.5.
I attached a simple test case with a recursive macro (see the two comments above).
Our test environment:
- Intel(R) Core(TM)2 Duo CPU based platform
- SMP linux kernel (2.6.24)
- Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_06-b05, mixed mode)
Maybe you need to run the test multiple times to reproduce the bug.

[jira] Updated: (VELOCITY-514) Rendering a template with inline

Posted by "Sam Chang (JIRA)" <de...@velocity.apache.org>.
[ https://issues.apache.org/jira/browse/VELOCITY-514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sam Chang updated VELOCITY-514:
-------------------------------
Attachment: slammer.vm
macroSlammer-1.5.jar
macroSlammer-1.4.jar
The previously attached jar did not run independantly.
Added macroSlammer-1.4.jar which uses velocity 1.4 with correct dependency and macroSlammer-1.5.jar using velocity 1.5 beta 2. You will also need slammer.vm in the same directory to run.
It does appear to be fixed (or reoccur less often) in velocity 1.5 beta 2.
cheers,
Sam

Ok, so this _is_ VELOCITY-24 . The fix went in between beta-1 and beta-2 and if he can not reproduce it with beta-2, then it is good. Resolving it for good.
