* fix(media): track cleanup ownership per path
Add explicit cleanup policy handling to MediaStore and count refs by path before deleting the underlying file. This prevents cleanup from removing shared files until the final ref is gone.
Refs #1886
* fix(tools): keep send_file refs forget-only
Mark send_file media registrations as forget-only so cleanup drops the ref without deleting the original workspace file.
Refs #1886
* fix(channels): declare managed media cleanup policy
Explicitly mark downloaded and managed channel media as delete-on-cleanup so media ownership is visible at each registration site.

io.ReadAll errors were silently discarded with `body, _ := io.ReadAll(...)`,
which could cause empty or partial data to be used for JSON unmarshaling
or error messages. This adds proper error checks for all instances.
The previous dedupe map rotation logic completely cleared the map when it reached max size, causing an 'amnesia cliff' where immediately arriving duplicates of just-forgotten messages would be processed.
This change replaces that with a MessageDeduplicator struct that uses a circular queue (ring buffer) to track insertions. When the limit is reached, it only evicts the absolute oldest message from the map, completely resolving the cliff issue.
This also cleans up the WeCom Bot and App webhook handlers by encapsulating the mutex and map state.
When the dedupe map rotates, the previous logic entirely cleared the map, meaning the message that triggered the rotation was immediately forgotten and could be duplicated immediately.
This change seeds the new map with the current message to prevent that. Also adds a defensive nil check.
Match rotation semantics to prior behavior by fully resetting the dedupe map
once the size limit is exceeded, and add focused tests for duplicate detection
and boundary rotation behavior.
Centralize dedupe map access behind a mutex-safe helper and use it in both
WeCom bot and WeCom app channels to eliminate concurrent map access races while
preserving current dedupe behavior.
- Introduced WeCom AIBot channel configuration in config.go with relevant fields.
- Implemented WeCom AIBot channel factory registration in init.go.
- Created unit tests for WeCom AIBot channel functionalities including initialization, start/stop behavior, webhook path handling, message encryption/decryption, and signature generation.
- Set default values for WeCom AIBot configuration in defaults.go.
* fix(tools): close resp.Body on retry cancel and cache http.Client instances
Fix resp.Body leak in DoRequestWithRetry where req.Body (request) was
incorrectly closed instead of resp.Body (response) on context cancel.
Cache http.Client on web search/fetch provider structs and channel
adapters (WeCom, LINE) to avoid per-call allocation overhead.
* fix(channels): preserve original http client timeouts for LINE and WeCom
Split LINE single 60s client into infoClient (10s) for bot info lookups
and apiClient (30s) for messaging API calls. Lower WeCom cached client
base timeout from 60s to 30s (matching uploadMedia), and ensure it is
always >= the configured ReplyTimeout so the per-request context
deadline remains the effective limit.
* refactor(tools): extract timeout consts and deduplicate WebFetchTool constructors
Address PR review feedback from xiaket:
- Define searchTimeout, perplexityTimeout, fetchTimeout, defaultMaxChars,
and maxRedirects as package-level consts instead of magic numbers.
- Remove misleading "No proxy" comment in NewWebFetchTool.
- Deduplicate NewWebFetchTool by delegating to NewWebFetchToolWithProxy.
* test(utils): add context cancellation test for DoRequestWithRetry
Verify that resp.Body is properly closed when the context is canceled
during retry sleep, covering the C8 resp.Body leak fix.
* fix(utils): close resp in test to satisfy bodyclose linter
* fix(utils): eliminate flakiness in context cancellation retry test
Synchronize cancellation using an onRoundTrip callback from the
transport wrapper instead of a timing-based context timeout. This
ensures the first client.Do completes before cancel fires, so
cancellation always hits during sleepWithCtx.
Cancel the constructor-created context before overwriting in Start()
to prevent the original cancel function from becoming unreachable.
Move len(processedMsgs) check inside the write lock to eliminate a
data race, and re-insert the current msgID after map reset to prevent
duplicate processing of the in-flight message.
Applies to both WeComBotChannel and WeComAppChannel.
The ctx field was only set in Start(), so tests calling handleMessageCallback
without Start() caused a nil pointer dereference in MessageBus.PublishInbound.
The HTTP request context is canceled as soon as the handler returns the
response, causing PublishInbound to fail with "context canceled" when
processMessage runs asynchronously in a goroutine. Use the channel's
long-lived context (c.ctx) instead.
Port changes that were applied to the old pkg/channels/*.go files on main
to their new locations in channel subpackages:
- telegram: precompile regex, var transcribedText, GetModelName()
- discord: var transcribedText declaration
- onebot: resp.Body.Close(), "canceled" spelling, remove empty line
- slack: named return values in parseSlackChatID
- wecom: remove sendMarkdownMessage dead code
- whatsapp: resp.Body.Close() after Dial
- gateway/helpers: remove unused errors import
Introduce SenderInfo struct and pkg/identity package to standardize user
identification across all channels. Each channel now constructs structured
sender info (platform, platformID, canonicalID, username, displayName)
instead of ad-hoc string IDs. Allow-list matching supports all legacy
formats (numeric ID, @username, id|username) plus the new canonical
"platform:id" format. Session key resolution also handles canonical
peerIDs for backward-compatible identity link matching.
