- Feature: Added `--security-config-path` option to zenserver to configure security settings
- Expects a path to a .json file
- Default is an empty path resulting in no extra security settings and legacy behavior
- Current support is a top level filter of incoming http requests restricted to the `password` type
- `password` type will check the `Authorization` header and match it to the selected authorization strategy
- Currently the security settings is very basic and configured to a fixed username+password at startup

"http" {
"root": {
"filter": {
"type": "password",

"password": {

"password": "<password>"

* Comma-separated logger specification now correctly deals with commas
* `GetSystemMetrics` properly accounts for cores
* cpr response formatter passes arguments in the right order
* `HttpServerRequest::SetLogRequest` can be used to selectively log HTTP requests

requests (#753)
* add IHttpRequestFilter to allow server implementation to filter/reject requests
|

mode (#745)
* only check file size for requested range in asio TransmitFileAsync in debug mode
* only do Transmit file for whole files

Run Windows service as an interactive session, so we correctly respond to RequestApplicationExit when requested to stop by the service manager

* implemented chunking for TransmitFile path, to ensure payloads exceeding the TransmitFile API limit of 4GB can be handled
* also fixes similar issue with memory path

* make sure we properly convert command line args for zenserver as well
* make sure we *add* wildcards/excludes in addition to defaults

This change primarily introduces improved logic for dealing with sending data from file references.
This is intended to reduce the amount of memory-mapping we end up doing when sending data from files. Windows now uses `TransmitFile` to send file data more efficiently using kernel-side I/O, but Linux/Mac basically behaves as before since they don't offer any true async file I/O support via asio. This should be implemented separately using a background I/O thread pool.
This PR also includes improved memory management for http/asio with reduced allocation counts, and a fix for a potential use-after-free in very high load scenarios.

* changed some logging string so they don't get caught in CI logging

this change adds OTEL tracing to a few places
* Top-level application lifecycle (config/init/cleanup, main loop)
* http.sys requests
it also brings some otlptrace optimizations and dynamic configuration of tracing. OTLP tracing is currently always disabled
|
| |
|
|
| |
* refactored `HttpServer` so all subclass member functions are proctected, to make it easier to extend base functionality
* added API service, can be used to enumerate registered endpoints (at `/api`). Currently only very basic information is provided
|
| |
|
| |
* implement --dedicated option on asio http server
|

|

this change makes it possible to use zenserver on hosts where IPv6 has been disabled

effective concurrency in zenserver can be limited via the `--corelimit=<N>` option on the command line. Any value passed in here will be used instead of the return value from `std::thread::hardware_concurrency()` if it is lower.
* added --corelimit option to zenserver
* made sure thread pools are configured lazily and not during global init
* added log output indicating effective and HW concurrency
* added change log entry
* removed debug logging from ZenEntryPoint::Run()
also removed main thread naming on Linux since it makes the output from `top` and similar tools confusing (it shows `main` instead of `zenserver`)

- Change BadAlloc exceptions in GC to warnings
- Add explict ASSERT exception catch in http plugin request processing
- Make exceptions handled in http request processing to warnings

* clean up trace command line options
explicitly shut down worker pools
* some additional startup trace scopes
|
| |
|
|
|
| |
* extend log on failed httpsys response
* fix formatting for "Desired port is in use, retrying"
* add warning log if port is remapped
|
| |
|
|

* Suppress progress report callback if oplog import detects oplog with zero ops
* output error code when catching system errors

This change adds more instrumentation for memory tracking, so that as little as possible comes through as Unknown in Insights analysis.

- Improvement: Add file and line to ASSERT exceptions
- Improvement: Catch call stack when throwing assert exceptions and log/output call stack at important places to provide more context to caller

this change adds support for tracing http payloads when using the asio path. This was already supported when using the `--http=plugin` path and this change moves some code into a shared class for reuse.

- Shared memory for zenserver state may hang around after all zenserver processes exit - make sure we find a valid entry in `zen up` before bailing
- Httpasio add retry for desired port
- Httpasio only call listen() once
- Httpasio explicitly close acceptor sockets
|
| | |
|
| |
|
| |
- Bugfix: Implement two listening sockets in ASIO (ipv4+ipv6) when either we start with `--http-forceloopback` or we resort to that mode because of a failure to bind to the "any" address
|

|
|

* added log level control/query to LoggerRef
* added debug logging to http plugin implementation
* added GetDebugName() to transport plugin interfaces
* added debug name to log output
|
| |
|
|
| |
* New option for zenserver - `--http-forceloopback` which forces opening of the server http server using loopback (local) connection (UE-199776)
* add fallback to local connection for asio if we get access denied on public port

this change aims to hide logging internals from client code, in order to make it easier to extend and take more control over the logging process in the future.
As a bonus side effect, the generated code is much tighter (net delta around 2.5% on the resulting executable which includes lots of thirdparty code) and should take less time to compile and link.
Client usage via macros is pretty much unchanged. The main exposure client code had to spdlog internals before was the use of custom loggers per subsystem, where it would be common to have `spdlog::logger` references to keep a reference to a logger within a class. This is now replaced by `zen::LoggerRef` which currently simply encapsulates an actual `spdlog::logger` instance, but this is intended to be an implementation detail which will change in the future.
The way the change works is that we now handle any formatting of log messages in the zencore logging subsystem instead of relying on `spdlog` to manage this. We use the `fmt` library to do the formatting which means the client usage is identical to using `spdlog`. The formatted message is then forwarded onto any sinks etc which are still implememted via `spdlog`.

separating the http server implementations into a directory and moved diagsvcs into zenserver since it's somewhat hard-coded for it
