EventStoreDB v5 Fail to run after using sudo

Asked 2020-Oct-27 at 11:42

I normally run eventstore with eventstore --run-projections=System but trying to run queries, macos throw a security complain: “libjs1.dylib” cannot be opened because the developer cannot be verified.

So I ran sudo eventstore --run-projections=System. This did not fix the issue. I wen to system preferences > security > general and gave access to libjs1.dylib and the Query ran and returned no value.

I realized all the data from event store was gone.

I though maybe it becase sudo? I ran without sudo and now I get this error:

Have you checked the docs? https://developers.eventstore.com/server/5.0.9/server/server/default-directories.html#macos

The data isn't gone, but the database path for the root user won't match the path for the regular user, so your database has been created elsewhere.

Here is the docs note:

On macOS you will get permissions error if you run eventstore without sudo. We advise changing the configuration file and change the Db option to a place where you have access as the normal user.

When running with sudo, the database is located at /var/lib/eventstore. I suspect then when you run it without sudo, the database was places under /usr/local/Caskroom/eventstore/5.0.8/EventStore-OSS-MacOS-macOS-v5.0.8 somewhere.

Honestly, I avoid running EventStoreDB on macOS from the cask and use Docker instead. It's more predictable, doesn't have issues and allows you to run different versions without issues.

APM Go Agent isn't Sending Data to the APM Server

Since you didn't mention it above: did you instrument a Go application? The Elastic APM Go "Agent" is a package which you use to instrument your application source code. It is not an independent process, but runs within your application.

So, first (if you haven't already) instrument your application. See https://www.elastic.co/guide/en/apm/agent/go/current/getting-started.html#instrumenting-source

Here's an example web server using Echo, and the apmechov4 instrumentation module:

Analyzing the stack trace, it looks you are attempting to allocate a far-too-large slice here: db_template.XCludeList.getAllCombinationComplex()

Using TCL: Sqlite syntax error when creating table in memory temp table

ANSWER

Answered 2018-Sep-22 at 17:42

Temporary tables go into the temporary database (which is named temp). While that database is stored in a disk file, the file is not actually written to until the cache overflows (because the temporary database is not required to be durable through a crash).

If you want to put the table into some other database, do not use CREATE TEMP TABLE but the normal CREATE TABLE.

The key is that since you only have a reference to the SearchOpts struct in your function, you can't move out of it.
