- rABC21a1e99e684d: [alias-server] Prevent reentrency in handleBlockConnected
Review new unit test
npm test
Note: this unit test is something of a stub right now. It will matter more when we are actually updating and changing the database. This is where we will be able to actually verify no reentrancy.

remove debug logging

| 66 ↗ | (On Diff #39639) | Yes, this is a debug log so I could check if the dependency was even working. More important to check this when we have actual async stuff happening in the loop where reentrancy would have an impact. Removed. |
| apps/alias-server/test/chronikWsHandlerTests.js | ||
| 191 ↗ | (On Diff #39639) | For now, this still doesn't really matter. Both loops will still return the correct info. Later on this test will be expanded to include database reads and writes, so that reentrancy would return a different value if it occured. |
