Connection/Subscription does not error
When a connection goes away we do not get an error for nats-sub example.
subscribe should have a "block" option
So it never ends the block, keeps hearing for new messages.
I can't see how to use creds file
I suspect that the feature is not implemented in Crystal lang
Crystal 0.31.0+, 0.32.0+ compatibility
- A patch is required for new modulo function/method.
The patch is provided by @Tails in commit Tails@d0e6cf5.
An addition ofrequire "big"is also required in nuid.cr.
Further patching is required for connection.cr, see daliborfilus@616e96a.
- Crystal 0.31.0 introduced many changes to Channel, removing Channel::Buffered in the process.
(https://crystal-lang.org/api/0.31.0/Channel.html)
The new implementation doesn't have #empty? method, which is used heavily in connection.cr.
If calls to@flush#empty?are removed, the connection deadlocks:
Unhandled exception: Attempt to lock a mutex recursively (deadlock) (Exception)
from /usr/share/crystal/src/mutex.cr:44:21 in 'lock'
from lib/nats/src/nats/connection.cr:132:5 in 'flush_outbound'
from lib/nats/src/nats/connection.cr:376:9 in 'close'
Can be seen via nats-pub binary:
$ ./bin/nats-pub -s localhost subject test
Published [subject] : 'test'
Error running at_exit handler: Attempt to lock a mutex recursively (deadlock)
I can't find any replacement for this, as far I can see.
TLS with self-signed certificate
Hello,
I have NATS server setup using a self-signed certificate.
When I try to connect to my cluster, I get the following error:
Unhandled exception: SSL_connect: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed (OpenSSL::SSL::Error)
from ../../../../../usr/local/Cellar/crystal/0.35.1_1/src/openssl/ssl/socket.cr:34:11 in 'initialize'

from ../../../../../usr/local/Cellar/crystal/0.35.1_1/src/crystal/main.cr:114:3 in 'main'
How do I correctly specify TLS options?
How can I deal with "slow consumer error" with this lib?
I want to detect the slow consumer state inside the subscription and resubscribe
