A root is submitted +to `tm_uhrp` only after its entire closure validates, `/renew` extends every +object's GCS `customTime`, and bounded GC preserves deduplicated objects while +any session or advertised root still references them. Existing UHRP APIs and +bucket object layouts remain compatible. + This guide walks you through deploying **UHRP Storage Server** on Google Cloud Platform (GCP) with continuous delivery via GitHub Actions. When you finish, you’ll have: - A single‑region **Cloud Storage bucket** that stores all UHRP data. diff --git a/infra/uhrp-server-cloud-bucket/package-lock.json b/infra/uhrp-server-cloud-bucket/package-lock.json index 56826e5a7..d9abea00d 100644 --- a/infra/uhrp-server-cloud-bucket/package-lock.json +++ b/infra/uhrp-server-cloud-bucket/package-lock.json @@ -1,12 +1,12 @@ { "name": "@bsv/uhrp-storage-server", - "version": "0.2.34", + "version": "0.2.35", "lockfileVersion": 3, "requires": true, "packages": { "": { "name": "@bsv/uhrp-storage-server", - "version": "0.2.34", + "version": "0.2.35", "license": "SEE LICENSE IN LICENSE.txt", "dependencies": { "@bsv/auth-express-middleware": "^2.2.2", diff --git a/infra/uhrp-server-cloud-bucket/package.json b/infra/uhrp-server-cloud-bucket/package.json index 4832b19f3..8d4484b9b 100644 --- a/infra/uhrp-server-cloud-bucket/package.json +++ b/infra/uhrp-server-cloud-bucket/package.json @@ -1,6 +1,6 @@ { "name": "@bsv/uhrp-storage-server", - "version": "0.2.34", + "version": "0.2.35", "overrides": { "brace-expansion": "5.0.9", "gaxios": "7.3.0", diff --git a/infra/uhrp-server-cloud-bucket/secrets/.env.example b/infra/uhrp-server-cloud-bucket/secrets/.env.example index f65164da1..2b88f51d7 100644 --- a/infra/uhrp-server-cloud-bucket/secrets/.env.example +++ b/infra/uhrp-server-cloud-bucket/secrets/.env.example @@ -53,6 +53,15 @@ UHRP_KEEP_ALIVE_TIMEOUT_MS=5000 UHRP_SOCKET_TIMEOUT_MS=60000 UHRP_MAX_REQUESTS_PER_SOCKET=1000 +# BRC-167 CHIRP complete-host closure limits.

Resume files contain opaque host session capabilities and +should be protected like other authenticated client state. +Storage hosts must use HTTPS unless `allowInsecureHTTP` (or the CLI's +`--allow-insecure-http`) is selected explicitly for local development. + +## Compatibility and limits + +- `uhrp:` and existing `StorageUploader`, `StorageDownloader`, `/upload`, + `/put`, `/find`, `/list`, `/renew`, and `/cdn` contracts are unchanged. +- CHIRP never introduces `tm_chirp` or `ls_chirp`; root discovery remains + `tm_uhrp` / `ls_uhrp`. +- Default atomic downloads are limited to 512 MiB. Streaming, object count, + concurrency, retry, depth, response size, and cache sizes are bounded and + configurable. +- Object requests and UHRP resolution have bounded timeouts. Browser clients + inherit the browser network boundary; server-side consumers can provide a + `urlPolicy`, and the CLI rejects DNS results outside public address space by + default. `--allow-private-hosts` is an explicit local-development override. +- Resolution of a future chunking profile remains hash-, length-, and + `contentHash`-verified, while `profileCanonical` reports `false` until the + profile-specific construction is understood. +- `mediaType` is untrusted advisory metadata. CHIRP integrity is not author + authenticity or permission to execute content. + +The BRC-167 serialization is authoritative if package behavior and the +standard ever disagree. + +## License + +Open BSV License v6.
