Standardize filter bar layout across admin pages to place search/filters
on left and action buttons on right within the same row, improving
visual consistency and space utilization.
Upstream accounts now use the standard APIKey type instead of a dedicated
upstream type. GetBaseURL() and new GetGeminiBaseURL() automatically append
/antigravity for Antigravity platform APIKey accounts, eliminating the need
for separate upstream forwarding methods.
- Remove ForwardUpstream, ForwardUpstreamGemini, testUpstreamConnection
- Remove upstream branch guards in Forward/ForwardGemini/TestConnection
- Add migration 052 to convert existing upstream accounts to apikey
- Update frontend CreateAccountModal to create apikey type
- Add unit tests for GetBaseURL and GetGeminiBaseURL
Replace manual header setting (Content-Type, anthropic-version, anthropic-beta)
with full client header passthrough in ForwardUpstream/ForwardUpstreamGemini.
Only authentication headers (Authorization, x-api-key) are overridden with
upstream account credentials. Hop-by-hop headers are excluded.
Add unit tests covering header passthrough, auth override, and hop-by-hop filtering.
- EditAccountModal: add Base URL / API Key fields for upstream type
- EditAccountModal: initialize editBaseUrl from credentials on upstream account open
- EditAccountModal: save upstream credentials (base_url, api_key) on submit
- CreateAccountModal: pass mixed_scheduling extra when creating upstream account
v0.1.74 merged upstream accounts into the OAuth path, causing requests
to hit the wrong protocol and endpoint. Add three upstream-specific
methods (testUpstreamConnection, ForwardUpstream, ForwardUpstreamGemini)
that use base_url + apiKey auth and passthrough the original body, while
reusing the existing response handling and error/retry logic.
- Change antigravitySmartRetryMaxAttempts from 3 to 1 to prevent
repeated rate limiting and long waits
- Clear sticky session binding (DeleteSessionAccountID) after smart
retry exhaustion, so subsequent requests don't hit the same
rate-limited account
- Add flow diagrams to Forward/ForwardGemini doc comments
- Add comprehensive unit tests covering:
- Sticky session cleared on retry failure (429, 503, network error)
- Sticky session NOT cleared on retry success
- Sticky session NOT cleared for non-sticky requests (empty hash)
- Sticky session NOT cleared on long delay path (handled by handler)
- Nil cache safety (no panic)
- MaxAttempts constant verification
- End-to-end retryLoop → switchError propagation with session clear
The digest chain fallback is only needed for Gemini endpoints, not
for the Anthropic Messages API path. Remove the handler integration
while keeping the reusable service/repository layer for future use.
The previous fallback (step 3) in GenerateSessionHash hashed system +
all messages together, producing a different hash each round as the
conversation grew ([a] -> [a,b] -> [a,b,c]). This made fallback sticky
sessions ineffective for multi-turn conversations.
Implement per-message Trie digest chain matching (reusing Gemini's Trie
infrastructure) so that the previous round's chain is always a prefix
of the current round's chain, enabling reliable session affinity.
Remove threshold-based waiting in both sticky session and antigravity
pre-check paths. When a model is rate-limited, immediately clear the
sticky session and switch accounts instead of waiting for short durations.
1. Frontend: replace hardcoded antigravityDefaultMappings with async
fetch from GET /admin/accounts/antigravity/default-model-mapping,
eliminating the duplicate data source that caused frontend/backend
mapping inconsistency.
2. Backend: convert handleSmartRetry and antigravityRetryLoop from
standalone functions to AntigravityGatewayService methods, enabling
Redis cache sync (updateAccountModelRateLimitInCache) after both
rate-limit write paths — long-delay branch and retry-exhausted branch.
- GetAccessToken: add upstream branch to read api_key from credentials
- shouldTriggerAntigravitySmartRetry: relax check from IsOAuth to Platform-based
- isModelSupportedByAccount/WithContext: replace IsAntigravityModelSupported
whitelist with mapAntigravityModel for unified scheduling/forwarding logic
- mapAntigravityModel: fix edge case where wildcard target equals request model
- Update tests for new behavior and add custom model_mapping test cases
Change formatTime() to include seconds (HH:MM:SS) instead of only
hours and minutes (HH:MM). This gives users more precise information
about when rate limits will reset.
The default fallback cooldown when rate limit reset time cannot be
parsed was 5 minutes, which is too aggressive and causes accounts
to be unnecessarily locked out. Reduce to 30 seconds for faster
recovery. Config override still works (unit remains minutes).
When extended thinking is enabled, Claude API requires max_tokens >
thinking.budget_tokens. If misconfigured, this auto-adjusts max_tokens
to budget_tokens + 1000 instead of returning a 400 error.
- Add ensureMaxTokensGreaterThanBudget helper function
- Extract Gemini25FlashThinkingBudgetLimit constant (24576)
- Log adjustment for debugging
Ensures consistent line endings for SQL migration files, Go source,
shell scripts, YAML configs, and Dockerfiles. Fixes checksum mismatches
on Windows where CRLF line endings cause migration hash differences.
