📝 Walkthrough

Walkthrough

The TTS Dockerfile now obtains FFmpeg and ffprobe from a pinned multi-architecture registry image. It validates both binaries and applies connection and total timeout limits to Piper and voice asset downloads.

Changes

TTS container asset setup

Layer / File(s)	Summary
Container asset acquisition and validation Web/Resgrid.Web.Tts/Dockerfile	The build copies FFmpeg and ffprobe from the pinned registry stage, makes them executable, and validates them with version commands. Piper and voice downloads now use connection and total-timeout limits.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to b6d7e

The Docker image build can spend roughly an hour retrying failed downloads, and non-amd64 builds may use an incompatible Piper archive. The PR is mergeable with explicit owner follow-up to bound download retries and select the correct architecture.

Select Piper by $TARGETARCH or restrict the image to linux/amd64.

Piper provides piper_amd64.tar.gz, piper_arm64.tar.gz, and piper_armv7.tar.gz, but line 59 always downloads the AMD64 archive. The fallback at line 65 also uses an x86_64 path.

curl official documentation --retry-max-time total time initial transfer retry semantics

💡 Result:

The --retry-max-time option in curl is used to set a total time limit, in seconds, during which curl is permitted to perform retries [1][2]. Its semantics and interaction with other options are summarized below: Retry Timer Mechanics: The retry timer begins before the first transfer attempt [1][3]. The --retry-max-time value acts as a ceiling for the duration of the entire retry process [2][3]. Before starting any new retry attempt, curl checks if the elapsed time since the beginning of the initial attempt has exceeded this limit [4]. If the timer has reached or exceeded this limit, curl stops retrying and gives up [1][3]. Interaction with Transfer Duration: The --retry-max-time option only limits the time spent waiting for and initiating retries [2][3]. If a transfer attempt has already started and is currently in progress, it is permitted to complete even if its duration causes the total time to exceed the --retry-max-time limit [1][4]. To strictly limit the duration of each individual transfer attempt, you should use the --max-time option [5][1]. Inclusion of Wait Times: The retry timer includes both the time spent on actual transfer attempts and the time spent sleeping between attempts (e.g., due to the default exponential backoff or the --retry-delay option) [4]. Relationship with --retry: The --retry option defines the maximum number of times curl will retry a failed transfer [5][2]. The process will terminate when either the maximum number of retries defined by --retry is reached, or the duration defined by --retry-max-time has elapsed, whichever happens first [2]. If --retry-max-time is set to zero (the default), there is no time limit on retries [1][3].

Limit retry time for every curl download.

Add --retry-max-time 600 to the Piper archive, voice model, and metadata downloads. Keep --max-time 600 because it limits each transfer attempt; --retry-max-time limits the retry period. Without it, six attempts can allow one download to run for about 3,600 seconds.
