  Fix issue 24040: Hide compose spinner on failed message send #39922

• I Found Two Bugs in Zulip. The Maintainers Had Filed Both Two Weeks Earlier.
  1 project | dev.to | 7 Aug 2026

  Issue #39650. Opened June 30, by the maintainers themselves: a systematic audit of the Slack import path, roughly a dozen items, confirmed and triaged. My two discoveries were on that list, described more precisely than I would have described them. I was two weeks late to my own findings.

• This Bug Has Never Fired in Production. I Fixed It Anyway
  1 project | dev.to | 5 Aug 2026

  TL;DR: get_batched_export_message_data() in Zulip's Teams importer yielded a batch list, then cleared and refilled the same object for the next batch. Safe for the current lazy consumer, silently destructive for any consumer that retains batches (starting with list(...)). My fix (zulip/zulip#39814) hands ownership of each yielded list to the consumer, plus a regression test that materializes the generator and fails on the old code with a concrete data-loss assertion: 24 != 29.

• The Bug That Crashes Your Import Is the Lucky One
  1 project | dev.to | 31 Jul 2026

  TL;DR: Zulip's Slack importer used float(message["ts"]) unguarded, both as a sort key and as date_sent. One message with a missing or malformed ts aborted the entire import; a non-finite value like "NaN" did not even raise, it silently broke the sort. My fix (zulip/zulip#39813) skips such messages with a warning and requires ts to parse to a finite float via math.isfinite. The regression test fails with KeyError: 'ts' on the old code.

• Ask HN: Who is hiring? (June 2026)
  11 projects | news.ycombinator.com | 1 Jun 2026

  Zulip is building the world’s best collaboration platform, and we’re committed to keeping it 100% open source. Zulip is the only modern team chat app designed for both live and asynchronous conversations. Our product serves as the communication hub for businesses, open-source projects, educators and communities around the world.

  We’re looking for a senior backend/infrastructure engineer to join our small core team and build, operate, and scale Zulip — both as we run it on Zulip Cloud, and as thousands of self-hosters run it themselves. The Senior Backend/Infrastructure Engineer will work across backend features, performance, and infrastructure; review code from both staff and open-source contributors; and share responsibility for keeping Zulip Cloud production healthy. You will also have the opportunity to provide technical direction and mentorship to the team.

  Zulip product lead here -- I'm not aware of anything in this space that used to work and no longer does.

  There's long been a way to make Zulip channels searchable with zulip-archive (https://github.com/zulip/zulip-archive), and that continues to be available.

  Making the app-native web-public channels accessible to search engines is a big technical project, tracked as https://github.com/zulip/zulip/issues/21881.

• Building a Zulip Style Collaborative Chat App with Next.js and Velt
  2 projects | dev.to | 5 May 2026

  Zulip’s design solves a problem most chat tools struggle with: conversations getting messy over time.

• How to Self-Host Zulip with Docker Compose
  1 project | dev.to | 15 Mar 2026

  Zulip is a self-hosted team chat platform built around topic-based threading. Every message belongs to a stream (like a channel) and a topic within that stream, so conversations stay organized even when dozens happen in parallel. This is fundamentally different from Slack and Teams where channels are a single chronological feed that becomes unreadable at scale. Zulip replaces Slack, Microsoft Teams, and Discord for teams that value async communication. It is fully open source (Apache 2.0), used by hundreds of open-source projects including the Lean theorem prover community and FOSS contributors who need structured discussion across time zones.
