26009fa434f2595ded075145fd322dc85dc6d518 braney Tue Sep 8 08:57:37 2026 -0700 ts: give each ticket sandbox its own trackDb cache Every user's CGIs write their trackDb cache into one shared cacheTrackDbDir. That is wrong for a park in two ways. The cached image is a shared-memory dump whose layout is tied to TRACKDB_VERSION in the binaries that wrote it, so a park built from a branch that touches the cache shares a directory with the live sandbox and with everybody else. And the writer leaves a name.txt beside each image and opens it with mustOpen, so whoever wrote it first owns the file and the next writer's CGI dies on a permission error - after the image itself has landed, so the next request succeeds and the failure reads as intermittent. Each ticket now gets NNNNN/trackDbCache inside its own sandbox. Unlike the udc cache this is derived from the code rather than data, so it is treated the opposite way: freeze clears it, since the binaries it belongs to have just been replaced, remove takes it with the sandbox, and conf retrofits it onto an instance frozen before this existed. refs #37867 diff --git src/utils/ts/ts src/utils/ts/ts index 54daf528004..3170ba94d5c 100755 --- src/utils/ts/ts +++ src/utils/ts/ts @@ -1,492 +1,521 @@ #!/bin/bash # # ts - "ticket sandbox": park a UCSC Genome Browser Redmine ticket as its own # frozen browser instance on hgwdev. refs #37867 # # A per-ticket Apache instance, owned by the developer, bound to a loopback high # port, reached by an ssh tunnel (yours or a colleague's - all hgwdev users # share the loopback, so anyone with an hgwdev account can tunnel in).
