* Run the agent as a Windows service.
This commit contains the boilerplate code for running the agent as a
Windows service.
We start the agent's main as a separate thread, although this is not
strictly required based on my experiments. We need similar logic for
calling netdata's exit function when someone wants to stop the agent.
However, at this point we need to resolve the issue of gaps when
running the agent as a service. It seems that sleeping for one second
with `sleep(1)`, actually sleeps for 2 to 4 seconds on my setup.
Once we resolve this, the work that remains concerns packaging: ie.
installing the binaries at the proper places so that the relevant
DLLs are found.
To test this PR you need to:
- Build the agent: ./packaging/utils/compile-on-windows.sh
- Install the files: `ninja -C build/ install`
- Copy the main binary: `cp ./build/netdata /usr/bin/`
- (Only once) Create the netdata service: `sc.exe config Netdata binPath="C:\msys64\usr\bin\netdata"`
- Start the service: `sc.exe start Netdata`
A couple notes:
- The health and the spawn client have been disabled for the time
being. They will be re-enabled once we finish the agent-as-service
issue and the packaging.
- Last time I checked, the agent crashes after a while when using
dbengine. In order to have something that works correctly, you
should specify memory-mode ram in your netdata.conf.
* Add windows version for sleep_usec_with_now
* Split install prefix from runtime prefix
These paths are always the same for non-Windows
systems. On Windows, RFS is the top-level
installation path.
With the current setup, Netdata will be installed
at C:\msys64\opt\netdata at packaging time. However,
the layout of the application means that when the
agent starts, it'll look as if everything was installed
at /.
* Do not use mold linker on Windows.
* Use modern UI for installer.
* Make the service delayed-auto
* Use mutexes instead of spinlocks.
* Update service handling logic.
* Add proper ifdefs for spinlock implementation.
* Initialize analytics spinlock
* Add a macro to build the agent as regular cli tool.
* Add makensis dependency
* Let installer know it's installing Netdata.
* Disable pluginsd on Windows
When pluginsd is enabled, the agent freezes approximately
20% of the time during startup.
* Add service description.
* Return pthread_join result
* Print tag when we fail to join a thread.
* Do not use mutexes instead of spinlocks.
* Assorted changes to service/main code.
* Rework service functions.
With the current implementation we are not getting any
MUTEX_LOCK errors and thread joining succeeds.
The only case where joining fails is the parallel initialization
of dbengine threads, which we can easily avoid by serializing
the initialization step.
* Rework main functions
This will allow someone to run the agent either as a service
or as a command-line tool.
* Change runtime prefix only when building for packaging.
* Install binaries and dlls.
* Make netdata claiming through UI work correctly.
* Fix netdata path
* Fix Coverity scan CI.
- Bail early in the script if the system isn’t 64-bit x86 Linux, since
it doesn’t actually work elsewhere.
- If a specific version of the Coverity tools was not specified, use
whatever version we end up with instead of failing. This means that
the CI will _just work_ instead of needing to be updated every few
months because the Coverity team does not understand the concept of
providing properly versioned download links.
* Fix typo.
* Explicitly disable logsmanagement plugin on known-broken environments.
Also, just disable it by default, because we don’t really support it.
* Fix logic for disabling logs management plugin.
