[BUG] too many processes spawned

[Jidehem]

Describe the bug The plugin can spawns to many Git processes, and the number of spawned processes is increasing until CPU limit is reached (~around 1000 processes on my machine)

To Reproduce Steps to reproduce the behavior:

1. Launch IntelliJ with the GitToolbox enabled
2. Open a complex project with around 10-15 different Git repositories
3. When checking in task manager, the number of tasks progressively increases up to 100% CPU is filled

Workaround Disable the GitToolbox plugin

Expected behavior The number of spawned processes should remain bounded and not exhaust machine's resources.

Plugin version 212.9.0

Note: the GitToolbox is not listed as I had to disable it in order to access the "About" menu...

Screenshots From Windows Task Manager: We can clearly see that the number of spawned processes is above 1000. Most of the commands are "Git for Windows". A lot of other processes are shells which are probably used to control "Git for Windows" (not visible on the screenshot)

Hi, could you check some of these processes to see what git command they are running ? With 15 repos I would not expect to see more than 50 but only when opening the project.

I've re-enabled the plugin and IntelliJ's sub-processes are always following the same tree structure

Using Process Explorer to get more infos, it appears that

• "C:\Program Files\JetBrains\IntelliJ IDEA 2018.2.5\bin\runnerw.exe" "C:\Program Files\Git\cmd\git.exe" -c credential.helper= -c core.quotepath=false -c log.showSignature=false tag -l --points-at 0604b96e103ed04ee913f43bf223c06f7feace39
  • \??\C:\WINDOWS\system32\conhost.exe 0x4
  • "C:\Program Files\Git\cmd\git.exe" -c credential.helper= -c core.quotepath=false -c log.showSignature=false tag -l --points-at 0604b96e103ed04ee913f43bf223c06f7feace39

Could you switch to EAP channel ? 212.9.5 should fix this

[Jidehem]

The issue seems to be fixed after updating to 212.9.5.
