datasette 1.0a29

⋅

Release: datasette 1.0a29

  • New TokenRestrictions.abbreviated(datasette) utility method for creating "_r" dictionaries. #2695
  • Table headers and column options are now visible even if a table contains zero rows. #2701
  • Fixed bug with display of column actions dialog on Mobile Safari. #2708
  • Fixed bug where tests could crash with a segfault due to a race condition between Datasette.close() and Database.close(). #2709

That segfault bug was gnarly. I added a mechanism to Datasette recently that would automatically close connections at the end of each test, but it turned out that introduced a race condition where an in-flight query could sometimes be executing in a thread against a connection while it was being closed. I ended up solving that by having Codex CLI (with GPT-5.5 xhigh) create a minimal Dockerfile that recreated the bug.
