1. etcp_on_down: add down_link param — log the specific lost link + remaining
Connection DOWN — link 192.168.40.247:2122 lost, remaining: [::1]:6669, [::2]:9970
Connection DOWN — closing, links: ... (for reinit/close)
2. etcp_on_link_down: pass the triggering link through to etcp_on_down
3. etcp_update_log_name: always check registry for node_name
(n_5a1b... → SM-A525F when name is available in registry)
Add helper functions server_type_str() and nat_type_str() to convert
CFG_SERVER_TYPE_* and NAT_TYPE_* codes to readable names.
Now: Add Socket type=PUBLIC instead of type=1
self-detect check: type=PUBLIC nat=UNKNOWN instead of type=1 nat_type=0
etcp_update_log_name: if name is empty, look up peer_node_id in topo_node_registry
and use node_name (e.g. 'SM-A525F') instead of empty or generic name.
Result: [45C2->03D3 [SM-A525F]] instead of [45C2->03D3 []]
- etcp_on_up: list up-link addresses after connection summary
- etcp_on_down: show all link addresses that were lost
- Link UP (server/client): add addr=X
- Connection established: add addr=X
- Link closed: add addr=X before traffic stats
- Link down (keepalive timeout): add addr=X
Now: [conn] Link 1 UP (server, mtu=1600, addr=192.168.40.247:2122)
- member_sync apply_items: empty payload is normal sync completion, not error
- topo_node_sqlite node_load: no addresses is normal for stub/seed nodes
- conn_mgr_core: node skipped when not in routing (normal for nodes w/o addrs)
- topo_group send_nodeinfo: downgrade ERROR→WARN in DEBUG category
- db_sync INIT_RESP: protocol details belong in DEBUG, not INFO
cm_invite_fail and cm_handle_invite_info_resp: always close invite's NCD
handle before freeing the invite struct. Previously the NCD close was
skipped when nq->handle != NULL (success path never closed it at all),
leaving cm_invite_ncd_callback registered with a dangling pointer.
On subsequent NCD DOWN event the stale callback caused SIGSEGV.
utun_instance_create() allocated with u_calloc (zeroed) but never
set etcp_connect_timeout_tb. utun_instance_create_from_config() had it
at line 371, but utun_instance_create (used by chatgui) was missing.
Timer with tb=0 fires instantly → CLOSE sent before handshake completes.
Diagnostics confirmed: value_tb=0, tb=0, delta_tb=0 on Windows chatgui.
- block_availability: status column (0=processing, 1=completed)
- md_ba_complete_block(): DELETE old + check exists + INSERT new id
- BLOCK_PROCESSING subcmd (0x10) — INSERT with new id, no REPLACE/IGNORE
- BLOCK_RELAY_FULL subcmd (0x11) — redirect when source/relay at capacity
- relay_block_ctx: downstream forwarding from chunk file
- md_file_load: per-file source download limit (max_downloads_per_file)
- RELAY_FULL from source node when at capacity
- relay_full handler: retry existing peers, not just new ones
- sync.md: full documentation
5 new tests in test_media_delivery_download:
- conn_cb starts only first block (backpressure)
- conn_cb with multiple peers
- BLOCK_DONE triggers next block relay from same peer
- assembly after all blocks validated
- peer with more blocks than dl (OOB fix verification)
md_dl_conn_cb made non-static for test visibility
md_dl_send added NULL guard for test instances without routing
media_download.h: added conn_cb extern declaration
- md_dl_send_block_req now takes explicit block_id (not peer-local index
into dl->block_ids) — fixes OOB 'aaaaaaaa...' garbage block_id
- conn_cb sends only first unstarted block per peer (backpressure)
- BLOCK_DONE success triggers next block from same peer
- conn_mgr handles stored in peer->cm_handle, closed on assembly/cancel
chat_core_attachment_download: use sqlite3_column_text for null-term
on_msg_inserted: copy data to local null-term buf before strstr
Both caused b64_decode to misread body from garbage memory
setVoiceMessageRoles now checks for '*' marker, translates URL-safe
base64 (-_ → +/) and decodes to restore original display data.
Fixes attachment filenames and voice waveform for new messages.
* prefix prepended in on_media_registered before b64 data
on_msg_inserted, chat_core_attachment_download, get_messages_json
only attempt b64_decode when prefix starts with '*' marker
Android: file picker → pending preview bar (name+size+X) →
combined send with text; cache copy, save dialog for downloads
Desktop: attach stores pending, preview bar before send,
combined with text in onSendClicked
C: attachment_sender.c — include filename in msg data for display
- _compute_bucket_hash: SELECT protocol, write proto byte
- _member_get_items: SELECT protocol, write proto byte
- _member_apply_items: consume proto byte in skip calculation
- topo_node_sqlite_channel_peers_all: SELECT protocol, write proto byte
All 5 writers and 5 readers now consistently include protocol byte.
- stcp_server_create: support AF_INET and AF_INET6 V6ONLY=1 (no dual-stack)
- Add listen_family to stcp_link_config
- init_sockets: return error (not partial) on any bind failure
- add chat_core_sync_my_addresses() call at chatgui startup
- collect_my_addrs: add proto byte (1=UDP, 2=TCP) to binary format
- chat_sync.c JOIN/WELCOME/PEER_UPSERT: read proto byte, write protocol column
- member_sync.c: read proto byte, dynamic protocol bind
- topo_node.c: debug logs for nodeinfo changed detection
- node_config.cpp: type=public for all servers
- Replace instance->stcp_server (single pointer) with stcp_servers linked list
- Add stcp_server_list_add/destroy_all/count API in stcp_link.h/c
- Fix port extraction for both AF_INET and AF_INET6 in init_sockets
- Filter out 0.0.0.0 and [::] addresses in chat_profile.c TCP address sync
- Add type=public to servers in node_config.cpp saveFull()
- conn_mgr_core.c: убрана запись node_name из cm_handle_invite_info_resp
- topo_node_sqlite.c: name в nodes не перезаписывается пустой строкой
- android_jni_bridge.c: bridge_get_node_name читает peers_<ch>.userinfo если nodes.name пуст
