Thank you for looking into this issue.

I am running jvm with jacocoagent which is creating this file but I ail to understand why file is getting corrupted.

-javaagent:/tmp/jacoco/jacocoagent.jar=destfile=/tmp/myproject_coverage/myprojectcoverage_${HOST}.exec,append=true,output=file,inclbootstrapclasses=true,inclnolocationclasses=true"

[Evgeny Mandrikov]

We can't tell you what causes corruption of file, because just snippet of your build.gradle is not enough to reproduce this. There are many potential reasons, listing some:

• something else performs access to this file, ignoring lock held by JaCoCo agent
• including case when multiple JaCoCo agents write to the same file, while filesystem doesn't properly support locking
• including case when JVM running one of such agents is not terminated gracefully but forcibly killed
• not forgetting the case of network filesystems
• including case of Docker volumes, which can cause troubles to certain types of file access - for example https://stackoverflow.com/questions/56066775/docker-container-cant-run-jacoco-agent-with-java-12#comment98799428_56066775
• maybe something else touches/write to this file
• disk is broken
• etc, etc

[rverm]

Thanks for the help! will check what is causing the issue.

[rverm]

The /tmp/abcuser/myprojectcoverage_.exec file which is getting created is too big in size with a lot of session entries which might be causing the corruption.

Is there a way I can limit .exec file size and when given size is reached create new  .exec file ?

(like loggers /tmp/abcuser/myprojectcoverage_1.exec /tmp/abcuser/myprojectcoverage_2.exec /tmp/abcuser/myprojectcoverage_3.exec and so on)

Hi,

JaCoCo writes exec files directly and does not use a logging framework for this. Therefore log configuration will not affect the way how JaCoCo exec files are written.

Hi,

some hints:

- The JaCoCo agent can be configured with append=false which will overwrite a existing exec files.

- For append=true new session dumps will simply be appended. There is no built-in option to rotate exec files

- You might adjust your launcher script to use a different filename for every launch (e.g. using a timestamp)

Regards,

The /tmp/abcuser/myprojectcoverage_.exec file which is getting created is too big in size with a lot of session entries which might be causing the corruption.

IMO this is very strange statement - how size can cause corruption?

unless if you are running out of space, but then how multiple files would help?

what is "too big" exactly?

 

Is there a way I can limit .exec file size and when given size is reached create new  .exec file ?

(like loggers /tmp/abcuser/myprojectcoverage_1.exec /tmp/abcuser/myprojectcoverage_2.exec /tmp/abcuser/myprojectcoverage_3.exec and so on)

In addition to what Marc said, let me point that all available options are documented - https://www.jacoco.org/jacoco/trunk/doc/

File size is almost ~8G. Will try to upload it here.

[Marc R. Hoffmann]

Oh no, please don't. We will not process this amount of data for you.

Instead explore the execfile locally with our command line utility execinfo. You will probably get an idea why it grows that big if you see the sessions and classes appended to the file.

:) I couldn't upload a 9GB file... 

Yes, I tried cli and find out multiple sessions entries with same classes appended to the .exec file.   Now I am  using append=false with jacocoagent this might resolve this issue.

You probably need a clear strategy when to dump execution data. A typical setup is:

1. Launch all services with JaCoCo agent attached
2. Execute all tests
3. Trigger exec dump for each service

Note that append=false can only be used when each service dumps to separate exec file. Otherwise data from other services will be overwritten.

hmm.. yes have 2 services started with jacoc agent attached and each dumping to separate exec files. 

And Myprojects has huge number of tests and each test when runs in regression start and stop services and dump data according to <host>.exec but now my worry is if 2 tests runs on same host only latest classes will be dump on exec file with append=false.

Is there a way to modify .exec file manually ?

If you dump data after every test case and if there is a huge number of them this explains why your exec files are growing.

Sure, if you use append=false the you will only see the coverage data from the last execution

A solution would be to merge exec data after every run with JaCoCo's merge functionality.

So what do you want to modify?

  Currently I am merging data after all tests finishes, I'll check how can I use this functionality to merge after each test.

So what do you want to modify? 

The 8GB file which I  have has  thousands of sessions entries with same classes. Would like to remove those duplicate sessions entries if i can.

This is exactly what JaCoCo merge does.
