… phase the regex compilation was done lazily on first access but did not properly synchronize for being accessed by multiple watcher goroutines between the option of adding a mutex for something that (should) only ever happen once and removing the potential for a race, this seems like the better choice

look good, we can move this logic to startup |

* chore: bump go to 1.23 (air-verse#650) * docs: update banner (air-verse#651) * fix proxy retry loop (air-verse#635) This addresses two bugs: 1) The loop could exit with an error condition present and fail to inform the user. 2) On Windows 11, syscall.ECONNREFUSED is not returned. Instead we receive net.OpError with a message similar to: "unable to reach app: Get "http://localhost:7000/": dial tcp [::1]:7000: connectex: No connection could be made because the target machine actively refused it." The Fix: Since the retry loop is short; just 1 second maximum, we retry until no error happens. If an error does occur, we inform the user. * Use web page address when making request to reload proxy (air-verse#625) * Use web page address when making request to reload proxy Signed-off-by: Alexandra Fishova <[email protected]> * Create event source with just a path because browser can handle address on its own.

This PR should fix #668 #655 and #530
The regular expressions, that are used to determine if files should be excluded, are compiled lazily on first request. This causes different kinds of timing related problems, including panics because multiple goroutines will end up compiling the expressions, while other goroutines may return with data that isn't complete.
