Bump dalli from 3.2.8 to 5.0.4

[dependabot]

Bumps dalli from 3.2.8 to 5.0.4.

Changelog

Sourced from dalli's changelog.

5.0.4

Bug fixes:

• Fix string_fastpath flag collision with compression (#1099)

  • ValueSerializer::FLAG_UTF8 and ValueCompressor::FLAG_COMPRESSED were both 0x2, causing Dalli::UnmarshalError on any UTF-8 string written with string_fastpath: true when compression is enabled, and silent encoding corruption for binary strings
  • Introduces Dalli::Flags to centralise bit flag constants; UTF8 is reassigned to 0x4
  • Adds regression test covering short/long UTF-8, binary, and cross-client read scenarios
  • Thanks to Jean Boussier and Mikael Henriksson for the fix and regression test

• Fix client-level string_fastpath: true being silently ignored (#1101)

  • Dalli::Client.new(servers, string_fastpath: true) had no effect; the fast path was only taken when string_fastpath: true was passed as a per-request option on each set call
  • Per-request option continues to take precedence over the client-level setting in both directions

5.0.3

Performance:

• Eliminate double array allocation in Client#perform (#1093)
  • Changed method signature from perform(*all_args) with destructuring to perform(op, key, *args), letting Ruby decompose arguments directly without intermediate array allocations
  • Reduces benchmark time by ~39% across all Dalli operations (get, set, delete, etc.)
  • Thanks to Sam Obeid for this contribution

Features:

• Support connect_timeout: keyword argument with resolv-replace >= 0.2.0, which now correctly forwards keyword arguments through its TCPSocket patch (#1096)

• Add Dalli::Instrumentation.disable! to allow disabling OpenTelemetry instrumentation at runtime (#1088)

  • Also exposes Dalli::Instrumentation.tracer= for setting a custom tracer

5.0.2

Performance:

• Add single-server fast path for get_multi, set_multi, and delete_multi (#1077)
  • When only one memcached server is configured, bypass the Pipelined* machinery (IO.select, response buffering, server grouping) and issue all quiet meta requests inline followed by a noop terminator
  • get_multi shows ~1.5x improvement at 10 keys and ~1.75x at 100–500 keys compared to the PipelinedGetter path
  • Thanks to Dan Mayer (Shopify) for this contribution

Development:

• Add bin/benchmark_branch script for benchmarking against the current branch

5.0.1

Performance:

[larouxn]

If I remember correctly this upgrade is generally fine gem wise, it's the underlying memcached version we're using that is the source of incompatibility since Dalli 5 contains changes that makes it a requirement to be on memcached 1.6+, IIRC.
