Issues when loading as dynamic module on macOS

[nemphys]

I just compiled the module as a dynamic module on macOS (nginx 1.19.7 installed via Homebrew) and when I add the load_module directive in nginx.conf and start the server, the error log gets flooded with the following errors (with high CPU utilization):

2021/02/28 11:05:10 [alert] 42874#0: worker process 49555 exited on signal 11
2021/02/28 11:05:10 [alert] 42874#0: cache manager process 49558 exited on signal 11

Turning on debug logging produces the following (repeatedly):

Any ideas?

[nemphys]

I just realised that my issue is the same as issue #39 (outstanding since 2019), so I guess it will never be solved (project seems to be abandoned?)
I tried building v1.3 and at least it seems to work (no streams support).

@nemphys can you show the ./configure parameters, I will try to reproduce the issue first

Any news on this one?

[waster]

The same issue for me trying to load dynamic module after compiling it with nginx 1.21.0-1~focal package from official repository on Ubuntu 20.04. Even with a sample minimal config:

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    access_log  /var/log/nginx/access.log;
}

[Lax]

This should be fixed by PR #66. Same root cause as #57/#42/#39: the combined HTTP+stream .so referenced stream symbols not available on all nginx builds. The module is now restructured into separate .so files:

• ngx_http_accounting_module.so — HTTP only, no stream symbols needed
• ngx_stream_accounting_module.so — Stream only (requires ngx_stream_get_variable_index exported)

For macOS / Homebrew builds:

./configure ... --add-dynamic-module=/path/to/traffic-accounting-nginx-module
make modules

Please rebuild and test with the latest code.

[Lax]

Fixed by separate HTTP/stream module builds (same root cause as #57). The HTTP module .so can now be loaded on any nginx without requiring stream symbol exports.
