From 7e5e2c73136bd59c5c2e2cc8601b98264be3fb01 Mon Sep 17 00:00:00 2001 From: therealaleph Date: Tue, 28 Apr 2026 03:15:26 +0300 Subject: [PATCH] ci(telegram): publish each release file individually to channel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New workflow + script that posts every artifact (Android APKs, Windows ZIP, macOS .app + CLI tarballs, Linux glibc + musl, OpenWRT, Raspbian) to the Telegram channel as separate sendDocument calls, each with a Persian caption naming the platform variant and a `#v` hashtag (e.g. `#v180`, `#v1810`, `#v200`) so users can find a specific release later via the channel's hashtag search. Files larger than 45 MB (the Bot API's effective ceiling after multipart + caption overhead) are split into byte chunks named `.part_aa`, `.part_ab`, ... and posted with reassembly instructions in the caption. For the v1.8.0 file set everything is ≤41 MB so the split path is defensive. Decoupled from `release.yml` so it can be re-triggered for any past tag via `workflow_dispatch` without rebuilding artifacts — downloads from the GitHub Release page directly via `gh release download`. Also auto-runs on each successful `release.yml` completion via `workflow_run`. Hard-codes the channel ID `-1003966234444` (one well-known channel, auditable in source). Reuses `secrets.TELEGRAM_BOT_TOKEN` which already has post permissions there.
