Pull Request Overview

This PR continues the incremental port of the TypeScript compiler with baseline test updates reflecting changes to output formatting, command-line invocation, and internal processing. The changes primarily update test baselines to match the new compiler's behavior patterns.

Key changes:

• Standardized test output formatting to use tsgo command instead of tsc
• Updated baseline outputs to include library references and diagnostic information
• Removed references to deprecated outFile option and related configuration errors

Seemingly still logical races or something; note the CI failure:

The CI is still racing, unfortunately; is there any way we could just not do the concurrency stuff and just make it slower but definitely correct?

[sheetalkamat]

i am looking at the race and checking whats the issue. I cant repro it on my windows laptop but looking at the log to see whats going on

[jakebailey]

Pretty shocked that this is how it used to work; was not aware this function was ever used outside services, and yet the old code did do this.

Is it actually necessary to collect info at this level of granularity? Would it be sufficient to just in the Program remember info from file loading to know file references or something?

[sheetalkamat]

Since this is a port, i would like to keep this as is and then we can revisit this part for better perf and understanding the scnearios. Its constrained to single function and should be easy to swap out to better logic later

[jakebailey]

Certainly, yes; I'm at least glad that this doesn't cause races.

Neat

Compare to tsc

• tsc first build, 8.8s
• tsc second build, 1.4s
• tsgo first build, 1.4s
• tsgo second build, 0.17s

So tsgo can quite literally do full incremental build skipping in the time it takes nodejs to start tsc.
