ogx-client 1.2.5 AsyncOgxClient api_key base_url Authorization header
💡 Result:
In the ogx-client Python SDK (specifically versions 1.1.4 and later, which include the 1.2.5 release), the AsyncOgxClient is used for asynchronous operations [1]. Authentication and Configuration The client automatically manages the Authorization header using an API key [1]. API Key: When you provide an api_key, the client automatically sets an Authorization: Bearer <api_key> header [1][2]. You can provide this in two ways: 1. Constructor argument: AsyncOgxClient(api_key="your-api-key") [1][3] 2. Environment variable: Set the OGX_CLIENT_API_KEY environment variable [1][3]. Constructor arguments take precedence over environment variables [1][2]. Base URL: You can configure the server endpoint using the base_url parameter [1]. 1. Constructor argument: AsyncOgxClient(base_url="http://your-server:port") [1][3] 2. Environment variable: Set the OGX_CLIENT_BASE_URL environment variable [1][3]. Example Usage import asyncio from ogx_client import AsyncOgxClient async def main: # The client will use OGX_CLIENT_API_KEY and OGX_CLIENT_BASE_URL # from the environment if not provided explicitly async with AsyncOgxClient( api_key="your-api-key", base_url="http://localhost:8321") as client: models = await client.models.list if name == "main": asyncio.run(main) Key Implementation Details - Precedence: Explicit constructor arguments > environment variables > default values [2]. - Authorization: If an api_key is provided, it sets the Authorization: Bearer header [1]. This takes precedence over any Authorization header manually included in default_headers or custom headers [2]. - Migration Note: In versions 1.1.4 and later, the library streamlined how configuration is handled compared to older versions [1]. Avoid using the older configuration patterns if you are on 1.2.5 [1].

…lementation) Author the behave scenarios for conversation compaction from the design document alone, ahead of the step definitions (LCORE-2230), so the test shape follows the intended behaviour rather than the implementation. The scenarios observe compaction strictly from outside the deployed stack — e2e steps never touch src/ (docs/testing/e2e_testing.md, "Choosing the Test Layer") — which leaves exactly the surfaces the design exposes over HTTP: - context_status on /v1/query responses: "full" while compaction never triggers, "summarized" once a three-turn conversation crosses the configured threshold (R7, driven by R1/R9 configuration). - The assistant still recalls a fact stated before the summary. - The Conversations API keeps serving every user query after compaction (R6). - /v1/streaming_query emits a compaction event before the first token and carries context_status in its end event (R12, R7). - enabled: false is a full off-switch: context_status stays "full" past the threshold. Buffer semantics, additive summarization, the summarization model and prompt, tiktoken estimation and per-conversation blocking are internal and belong to the integration layer (LCORE-1574). Fixtures: lightspeed-stack-compaction.yaml and lightspeed-stack-compaction-disabled.yaml per mode, derived from the mode's base configuration. They register a deliberately small context window for the CI model (openai/gpt-4o-mini: 2000 tokens) and a 10% threshold above a 100-token floor, so three turns cross the trigger; the real provider window is untouched, this only drives the local estimate. The window key is model-specific, so the scenarios that need it carry @openai-only, the same gating the unified-mode boot scenarios use on the providers matrix. tests/e2e/test_list.txt gains the feature; behave --dry-run parses it with the nine new step patterns reported as undefined and every other step matched.
…ature to three scenarios Review rework of the conversation-compaction feature file. Scenarios. The six scenarios collapse into three. The base-config "full" scenario duplicated the disabled one and is gone. The "summarized", "recall" and "history" scenarios exercised the same three turns and are now one scenario; the streaming and disabled scenarios stay separate because they observe different surfaces (the SSE stream, the off switch). Deterministic trigger. The old scenarios relied on three ordinary queries adding up to the threshold, so the crossing turn depended on response length. Now the first two turns ask the model to reply with "OK" only and each plants one fact, and the third query is a fixed 248-token paragraph that crosses the 200-token threshold on its own (2000-token window, ratio 0.1, floor 100). With buffer_turns 1 nothing can be summarized before the third turn, so context_status is asserted "full" on turns one and two and "summarized" on turn three. The third query also asks for both facts: turn one is in the summary, turn two is the verbatim buffer, so one answer covers summary recall and buffer recall. Fixtures. The pii-redaction shield is dropped: it cost tokens on every turn and its \d+ rule would have rewritten the cluster name the recall assertion looks for. context_windows now lists every provider/model pair the e2e workflows run (openai, azure, google-vertex, watsonx, aws-bedrock) instead of only openai, and the @openai-only tags go away with it. The vLLM runs take their model id from an env var and context_windows keys are not env-substituted, so they are not listed. Skip. The feature is tagged @Skip at feature level until LCORE-2230 lands the nine step definitions; Konflux runs the whole test list and would fail on undefined steps. The description drops the R-references. Rebased onto main after the OGX rename: the server-mode fixtures now read the OGX host from E2E_OGX_HOSTNAME like the base fixture does.
…eature Implements the step patterns the LCORE-1673 feature file left undefined, observing compaction from outside the deployed stack only: the context_status field on query responses, the compaction event and the end event's context_status on the native stream, and the user queries the Conversations API keeps serving after compaction. Nothing here imports or runs anything under src/; the internals are integration tests (LCORE-1574). The feature loses its @Skip tag and @cfg_compaction joins the "other" GitHub shard and the Makefile's default tag expression, so the scenarios run in CI from this change on. One gate step, "the active model has a registered context window", skips a scenario when the active provider/model has no entry under inference.context_windows in the copied lightspeed-stack.yaml. The provider workflows run the whole test list, and the vLLM-backed runs (rhaiis, rhelai) take their model id from an env var that mapping keys cannot pick up, so without the gate those runs would wait for a "summarized" status that can never arrive.

Description
Implements LCORE-2230: the step definitions for
conversation-compaction.feature(LCORE-1673, #2611; this PR is stacked on that branch and carries its commits), plus the CI wiring. After this lands the three compaction scenarios go from skipped to executing.Five patterns in

The vLLM-backed runs take their model id from an env var, andcontext_windowskeys are not env-substituted, so those runs have no window entry, the trigger never fires and asummarizedassertion could never pass. The gate resolves the fixture source path the same wayconfigure_servicedoes (not the repo-root copy, which Prow never writes because the config goes into a ConfigMap) and skips viacontext.scenario.skip, the same pattern the shield steps use in library mode.CI: the feature loses its
