Problem matcher with type "shell" randomly fails to match on Linux when the terminal is not "reused" #111068
Description
- VSCode Version: 1.52.0-insider (also repros with 1.51.0)
- OS Version: Ubuntu 20 (via Windows/WSL)
Steps to Reproduce:
- You may need to install gcc (sudo apt-get install gcc).
- Open folder.
- Create a test.c file with
int main(void) {
int i;
&printf("Hello");
&printf("Hello");
&printf("Hello");
return 0;
}
- Create a tasks.json with
{
"version": "2.0.0",
"tasks": [
{
"label": "build",
"type": "shell",
"command": "/usr/bin/gcc",
"args": [
"-Wall",
"${workspaceFolder}/test.c",
"-o",
"helloWorld"
],
"problemMatcher": {
"owner": "cpp",
"source": "gcc",
"fileLocation": [
"autoDetect",
"${workspaceFolder}"
],
"pattern": {
"regexp": "^(.*?):(\\d+):(\\d*):?\\s+(?:fatal\\s+)?(warning|error):\\s+(.*)$",
"file": 1,
"line": 2,
"column": 3,
"severity": 4,
"message": 5
}
},
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
If you're on VS Code non-Insiders, you'll need to save and Reload Window due to a bug that's fixed in Insiders.
4. Use Configure Default Build Task (I didn't originally think this was required because the tasks.json was already marked as isDefault).
5. Ctrl+Shift+B (Run Build Task).
6. You can repeat the repro via enter a key in the Terminal window and using Ctrl+Shift+B again (or doing a Reload Window, which is slower). Another alternative to repeat the repro is to use Ctrl+Shift+B quickly 2 times in a row (one time won't work).
Bug: The problem matcher gives random results 0-5.
Note: Screenshot uses test2.c instead of test.c (it doesn't matter).
Does this issue occur when all extensions are disabled?: Yes
Repros with the C/C++ disabled or enabled. With the C/C++ extension disabled with the "cppbuild" task, the bug repros still and also doesn't require step 6 to "reset" the repro (i.e. you can just use Ctrl+Shift+B repeatedly).
