SubGit Java堆空间

Question

While running SubGit I'm finding that the default Heap Size isn't adjustable, as I'm basically running:

subgit install foo.git

With the settings contained therein.

When checking the max heapsize with jmap -heap {pid} I can see 5022Mb allocated - while I have 20Gb allocated to the VM.

Same is true with java -XX:+PrintFlagsFinal -version | grep HeapSize java -XX:+PrintFlagsFinal -version | grep HeapSize leading me to believe that Subgit is using the default Java Heap value.

As I'm in a VM, I need to adjust this dynamically.

Is there a way to set SubGit heap size directly when launching the application? Or is there a way to update the default Java value?

Cheers

SubGit daemon's settings indeed cat be set in the configuration file by using "javaOptions" configuration options as Petr has mentioned. For example, for 512MB heap:

[daemon]
javaOptions = "-noverify -client -Djava.awt.headless=true -Djna.nosys=true -Xmx512m"

To add more memory to SubGit standalone executable (not daemon), edit SubGit launching script and change EXTRA_JVM_ARGUMENTS line, like:

EXTRA_JVM_ARGUMENTS="-Dsun.io.useCanonCaches=false -Djava.awt.headless=true -Djna.nosys=true -Dsvnkit.http.methods=Digest,Basic,NTLM,Negotiate -Xmx512m"
