method: timestamp does not run when generates: path is missing

[tyro-jason]

my-task:
    desc: does useful things
    cmds:
      - echo "I ran yo"
    sources:
      - [insert some path to source files]
    generates:
      - [insert some path to generated file]
    method: timestamp  

• Task version: Task version: v3.26.0 (h1:NfYktTh/XXJUFtUFdle+BZFtvGlmhk4Q7YfoeOBLPlE=)
• Operating system: Darwin
• Experiments enabled: no

If i add method timestamp then the task is not run when the output is not there... (like after a clean operation)

I also experienced this issue using the latest version. Every condition is the same, except that I'm running this on Linux (Manjaro).

+1 to this.

@andreynering — could we consider adding a check to the IsUpToDate function to mark a task as outdated if any of the generates files are missing?

Any ideas how this would work with glob patterns (generate doesn't just have to be a list of explicit files).

Or, perhaps the file existence check can only work if you're using explicit list (non-glob) file specifications.

All of these have surprising (in a bad way) behavior, though the current behavior for the normal case is very broken.

Have fix for this just waiting for a review #2716
