Introduce a new `template-bus` crate that provides greeting, names, and version functionality, along with corresponding tests. This crate serves as a bus module for the template system, enabling modular and testable components. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a Python exception is raised with a type that does not match the expected error type, the runtime now correctly propagates the error instead of silently ignoring it. This ensures that type mismatches in Python error handling are surfaced to the caller rather than being lost. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the distribution index file is not present, the Python runtime now returns an empty result instead of panicking. This allows the system to operate correctly in environments where the index has not yet been generated. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Fix the host address validation logic in the Python distribution module to properly handle edge cases such as empty strings and malformed addresses. Previously, invalid addresses could pass validation, leading to runtime errors during host registration. This change ensures that only well-formed addresses are accepted, improving reliability of the distribution system. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the system module is not available in the Python runtime, the bindings now gracefully return an error instead of panicking. This ensures that users receive a clear diagnostic message when attempting to access system functionality in environments where it is not supported. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The Python runtime now correctly handles the case where a layout field is absent, preventing a panic when accessing an optional attribute that was previously assumed to always be present. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a pool worker process exits unexpectedly, the harness now catches the resulting error and logs a warning instead of crashing. This improves robustness during worker lifecycle management. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test module was incorrectly imported using a relative path that failed when the harness module was invoked from outside its directory. Changed the import to use the crate's absolute module path, ensuring tests can be discovered and run regardless of the current working directory. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…provider Replace the template greeting module with a full Python runtime provider that answers the router's five questions about Python: which host interpreters to use, which standalone build to install, where the interpreter lives inside the archive, what a warm Python worker looks like, and the version floor to target. This change also renames the crate from `template` to `tinyruntime-python`, adds the `reqwest` HTTP client for querying the release index, and updates the bus contract to use `tinyruntime-bus` instead of `template-bus`.

Update cross-references in module-level documentation to match the current code structure. The `index` submodule is now private, so the doc comment in `distribution/mod.rs` refers to it as "the private `index` submodule" instead of using a public path. The error documentation for `select` now references `select_from` instead of the old `index::select` function name. In `lib.rs`, the `harness` module link is updated to use the explicit `mod@harness` syntax for correct intra-doc linking. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Replace the generic Rust template setup checklist and two-crate split guidance with project-specific documentation for the tinyruntime-python provider. The new text describes the provider's role, its five TinyBus members, the vendored wire contract, and the key differences from Node.js that affect Python worker management. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…content Update MODULE.md, README.md, and ROADMAP.md to describe the Python provider for tinyruntime instead of the Rust module template. The module now answers five provider questions about Python and does not perform installation or execution itself. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the tinyruntime submodule to the vendor directory, pinning it to commit 8106f3c to include the runtime dependency for the project. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
tinybus_module! builds a module manifest object path from its bus name, so providers sharing one path would ship manifests disagreeing with the objects they export. Each provider now serves at the path derived from its own bus name, and the router derives the same path when routing. Co-authored-by: Medulla <medulla@tinyhumans.ai>

Inline comments:
In @.github/workflows/ci.yml:
- Around line 75-76: The dependency policy check assigned to forbidden must
evaluate the complete normal/build graph for tinyruntime-bus rather than relying
on the current partial substring denylist. Replace the grep filtering with an
explicit package allowlist or an equivalent complete policy check that rejects
all disallowed async runtimes, HTTP clients, and native-library crates while
preserving the CI failure behavior.
In `@crates/tinyruntime-python/src/distribution/host.rs`:
- Around line 29-35: Add the Windows x86 mapping to the host-target match,
returning the i686-pc-windows-msvc-install_only.tar.gz artifact when arch is
x86. Extend the mapping tests to cover this new target and the existing Windows
aarch64 mapping.
In `@crates/tinyruntime-python/src/distribution/index.rs`:
- Around line 54-58: Update the error documentation for select_from to list only
Error::InvalidVersion and Error::NoMatchingBuild; leave the
Error::UnsupportedHost documentation on the outer distribution::select function.
In `@crates/tinyruntime-python/src/harness/pool_worker.py`:
- Around line 33-45: Validate _TOKEN alongside _ADDRESS before attempting the
connection, using the existing one-line stderr diagnostic and exit behavior for
either missing protocol setting. Wrap _ADDRESS.rsplit and port conversion in the
startup validation/connection handling so malformed addresses or non-numeric
ports produce the intended protocol connection failure message instead of an
uncaught ValueError.
- Around line 142-158: Move the ITIMER_REAL disarm out of the finally cleanup
and perform it within the try path before job execution returns, then ensure
descriptor restoration in finally cannot be interrupted or propagate an
exception. Preserve cleanup of saved descriptors 0/1/2 even if flushing or timer
handling fails, so later jobs retain valid standard streams.
In `@crates/tinyruntime-python/src/layout/mod.rs`:
- Around line 31-35: Update describe and the Unix find_interpreter logic to
search the known bin directory for versioned python3.N executables when python3
and python are absent, probing candidates until one satisfies RuntimeSettings.
Preserve the existing interpreter-selection behavior and add a regression test
covering a python/ directory containing only python3.12.
In `@crates/tinyruntime-python/src/system/test.rs`:
- Around line 45-48: Refactor the tests around
a_bare_command_resolves_through_path and the detect(&settings) ceiling test to
avoid host PATH and installed-interpreter dependencies. Extract helper variants
that accept explicit search paths and probe commands, then use tempfile-backed
fixtures with controlled executables and settings so both tests remain
deterministic.
In `@crates/tinyruntime-python/src/tinybus_module/mod.rs`:
- Around line 84-96: Update setup to construct the HTTP client through
Client::builder(), configuring both request timeout and connect timeout before
building it. Propagate builder failures by mapping the build error into
TinyBusResult<()> instead of allowing Client::new() to panic, then pass the
successfully built client to PythonProvider.
In `@crates/tinyruntime-python/src/tinybus_module/README.md`:
- Around line 1-20: Update the README to document the current Python provider
implementation: replace stale GreetingService/greet/Greet references with
PythonProvider and its Describe, DetectSystem, SelectDistribution, Layout, and
Harness methods; reference tinyruntime-bus and
tinyruntime_bus::names::PROVIDER_METHODS; point loader verification to the
tinyruntime-python example; and remove the obsolete generated-project guidance.
In `@crates/tinyruntime-python/src/tinybus_module/test.rs`:
- Around line 146-164: Update distribution::select to validate settings.version
before calling fetch_release, reusing index::select’s version parsing or
equivalent validation so invalid floors such as “latest” return
Error::InvalidVersion without any network request. Preserve normal release-index
selection for valid version floors.
In `@crates/tinyruntime-python/src/version/mod.rs`:
- Around line 59-65: Update parse_version so a present patch component must
begin with digits, returning the existing invalid-version result for values such
as “3.12.nope”, and reject any components after the patch component such as
“3.12.4.5”. Add regression cases covering both malformed forms.
- Line 52: Change parse_version to return the crate’s Result<Version> type and
add a dedicated error variant for generally unparseable version strings. Retain
a private optional parser for asset filtering, update affected callers and
documentation to use the appropriate parser, and adjust tests for the new
Result-based behavior.
In `@crates/tinyruntime-python/tests/harness_protocol.rs`:
- Around line 34-49: Update interpreter to verify that each candidate reports
Python major version 3 before returning it; retain the existing
executable-status check and continue probing the next candidate or return None
when the version cannot be confirmed.

Make the dependency policy check complete.
The command on Lines 75-76 uses a partial substring denylist. It misses other async runtimes, HTTP clients, and native-library crates, such as async-std, smol, curl, native-tls, and cc. A forbidden dependency can pass CI while the step reports the tinyruntime-bus contract as clean. Replace the grep with an explicit package allowlist or another policy check that evaluates the complete normal/build dependency graph.

Correct the select_from error contract.
select_from can return Error::InvalidVersion and Error::NoMatchingBuild. It does not call host_suffix or construct Error::UnsupportedHost. Keep the unsupported-host error documentation on the outer distribution::select function.

Validate the protocol environment before connecting.
Two startup paths bypass the one-line diagnostic this block establishes for a missing address.
- A missing
TINYRUNTIME_PROTOCOL_TOKENleaves_TOKENasNone. The worker then sends"token": nulland the router rejects the handshake with no explanation from this side. _ADDRESS.rsplit(":", 1)raisesValueErrorwhen the value has no colon, andint(_port)raisesValueErrorwhen the port is not numeric.except OSErrordoes not catch either, so the worker dies with a raw traceback instead of the intended message.
Treat a missing token the same way as a missing address, and catch the parse failure.

Disarm the timer before the finally block, so a late SIGALRM cannot break the worker.
setitimer(ITIMER_REAL, 0) runs inside finally. If the alarm fires after exec returns but before the disarm completes, _JobTimeout propagates out of finally. The descriptor restore on lines 153-158 never runs, so fds 0/1/2 stay bound to this job's temp files. main then answers through _failure, and every later job on this worker writes its output into closed temp files instead of the reply.
Disarm first inside the try, and make the restore itself unable to escape.
🐛 Proposed fix for the alarm race
try:
# Fresh globals per job, so a name defined by one job is not visible to
# the next one on this worker.

reqwest 0.12 Client::new ClientBuilder timeout connect_timeout source docs rustls-tls
💡 Result:
In reqwest 0.12, the Client and ClientBuilder are the primary types for managing HTTP requests [1][2]. Client::new Constructing a client with Client::new uses default configurations [1][3]. Notably, this method will panic if it fails to initialize the TLS backend or load system configuration [1][3]. For production use or scenarios requiring error handling, it is recommended to use Client::builder.build instead, as it returns a Result that can be handled gracefully [1][2]. ClientBuilder The ClientBuilder is used to customize the client's behavior, such as timeouts and TLS settings [2]. Timeouts: - connect_timeout(duration): Sets the maximum duration for the entire connection establishment process [4][2]. - timeout(duration): Sets the overall timeout for the entire request, including connection, redirect, and response reading. TLS (rustls-tls): The rustls-tls feature enables the use of the rustls library as the TLS backend. In reqwest, TLS configuration—including the choice of backend—is managed via features and ClientBuilder methods [5]. If the crate is compiled with the rustls-tls feature, it is typically used by default or can be selected if multiple TLS backends are available. You can further configure TLS behavior (such as adding certificates) directly on the ClientBuilder [5]. Example usage: use std::time::Duration; use reqwest::Client; let client = Client::builder.connect_timeout(Duration::from_secs(10)).timeout(Duration::from_secs(30)).build.expect("Failed to create client");

Build the HTTP client fallibly and configure request timeouts.
Client::new() can panic during TLS or system-configuration initialization. Use Client::builder() with timeout and connect_timeout, then map build() failures into TinyBusResult<()>.

Validate the version floor before fetching the release index. distribution::select fetches the index before index::select parses settings.version. Therefore, "latest" can return Error::IndexUnavailable instead of Error::InvalidVersion, and this test performs a network request. Reject invalid floors before fetch_release.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reject malformed patch components and extra components.
parse_version("3.12.nope") returns 3.12.0. parse_version("3.12.4.5") returns 3.12.4. As a result, distribution::index::select accepts malformed configured bounds and can select a distribution instead of returning Error::InvalidVersion.
Reject a present patch segment with no leading digits. Reject input with components after the patch segment. Add regression cases for both forms.
Proposed fix
- let patch = parts
- .next()
- .and_then(|segment| {
+ let patch = match parts.next() {
+ Some(segment) => {
let digits: String = segment.chars().take_while(char::is_ascii_digit).collect();

Confirm the candidate is Python 3 before accepting it.
--version exits successfully on Python 2 as well, so python can be accepted here when it is Python 2. pool_worker.py uses f-strings, so the worker then fails to start, no handshake arrives, and launch panics at line 96 with "the harness connected back". The suite reports a protocol fault instead of skipping, which is what the module doc on lines 8-9 promises.
Check the reported major version.

- Around line 75-76: The dependency policy check assigned to forbidden must
evaluate the complete normal/build graph for tinyruntime-bus rather than relying
on the current partial substring denylist. Replace the grep filtering with an
explicit package allowlist or an equivalent complete policy check that rejects
all disallowed async runtimes, HTTP clients, and native-library crates while
preserving the CI failure behavior.
In `@crates/tinyruntime-python/src/distribution/host.rs`:
- Around line 29-35: Add the Windows x86 mapping to the host-target match,
returning the i686-pc-windows-msvc-install_only.tar.gz artifact when arch is
x86. Extend the mapping tests to cover this new target and the existing Windows
aarch64 mapping.
In `@crates/tinyruntime-python/src/distribution/index.rs`:
- Around line 54-58: Update the error documentation for select_from to list only
Error::InvalidVersion and Error::NoMatchingBuild; leave the
Error::UnsupportedHost documentation on the outer distribution::select function.
In `@crates/tinyruntime-python/src/harness/pool_worker.py`:
- Around line 33-45: Validate _TOKEN alongside _ADDRESS before attempting the
connection, using the existing one-line stderr diagnostic and exit behavior for
either missing protocol setting. Wrap _ADDRESS.rsplit and port conversion in the
startup validation/connection handling so malformed addresses or non-numeric
ports produce the intended protocol connection failure message instead of an
uncaught ValueError.
- Around line 142-158: Move the ITIMER_REAL disarm out of the finally cleanup
and perform it within the try path before job execution returns, then ensure
descriptor restoration in finally cannot be interrupted or propagate an
exception. Preserve cleanup of saved descriptors 0/1/2 even if flushing or timer
handling fails, so later jobs retain valid standard streams.
In `@crates/tinyruntime-python/src/layout/mod.rs`:
- Around line 31-35: Update describe and the Unix find_interpreter logic to
search the known bin directory for versioned python3.N executables when python3
and python are absent, probing candidates until one satisfies RuntimeSettings.
Preserve the existing interpreter-selection behavior and add a regression test
covering a python/ directory containing only python3.12.
In `@crates/tinyruntime-python/src/system/test.rs`:
- Around line 45-48: Refactor the tests around
a_bare_command_resolves_through_path and the detect(&settings) ceiling test to
avoid host PATH and installed-interpreter dependencies. Extract helper variants
that accept explicit search paths and probe commands, then use tempfile-backed
fixtures with controlled executables and settings so both tests remain
deterministic.
In `@crates/tinyruntime-python/src/tinybus_module/mod.rs`:
- Around line 84-96: Update setup to construct the HTTP client through
Client::builder(), configuring both request timeout and connect timeout before
building it. Propagate builder failures by mapping the build error into
TinyBusResult<()> instead of allowing Client::new() to panic, then pass the
successfully built client to PythonProvider.
In `@crates/tinyruntime-python/src/tinybus_module/test.rs`:
- Around line 146-164: Update distribution::select to validate settings.version
before calling fetch_release, reusing index::select’s version parsing or
equivalent validation so invalid floors such as “latest” return
Error::InvalidVersion without any network request. Preserve normal release-index

What changed
Replaces the template with
tinyruntime-python: the Python provider fortinyruntime.This module answers five questions about Python and does nothing else. It
downloads nothing, installs nothing, and starts no worker — the router owns all
of that, identically for every language. The one network call it is allowed is
reading the
astral-sh/python-build-standalonerelease index.DescribeDetectSystemSelectDistributionLayoutHarnessThe Python knowledge, in four parts
3.12means "3.12 or newer". Thatfollows from the channel: it publishes a moving set of builds rather than one
archive per version, so an exact pin would stop resolving the moment that build
rotated out. An exclusive ceiling is how a caller stays off a newer series —
which is what keeps selection away from a 3.15 release candidate sitting in the
same index as the 3.12 builds it actually wants.
python3.12is tried beforepython3. On a machine with severalinterpreters,
python3is whatever the distribution chose and is often olderthan the versioned binary right next to it.
python, whatever the version.So the install directory is named from the asset — otherwise every version
would claim one cache directory and each install would silently replace the last.
worker-thread equivalent and no safe way to kill a running thread, so jobs on a
warm worker share module state,
os.environ, and logging configuration. Theharness gives each job fresh globals and captures output at the
file-descriptor level; the router recycles workers after a job budget. That
bounds the leakage without eliminating it, which is why Python pooling is
opt-in rather than default — an asymmetry with Node that is deliberate and
documented rather than an oversight.
Public API / behaviour changes
New repository content — the template's
greetingsurface is gone. The contracttypes come from the vendored
tinyruntime-bus; no payload type is redefined here.Validation

The harness is the onlypart of this crate that is not Rust. Those 13 tests stand in for the router
against a real
python: worker reuse, fresh globals between jobs, surviving araise and a
sys.exit(3), descriptor-level capture (includingos.write(1, ...)and a subprocess's output), cwd sandboxing and restoration between jobs,
SIGALRMsoft deadlines, stdin at EOF, and that a job cannot forge a reply. They skip when
the machine has no Python 3.
Notes for the reviewer
src/distribution/index.rsholds the index shape and the ranking, testedagainst a realistic index body that deliberately includes the assets which must
be ignored (debug archives,
SHA256SUMS) and a near-miss host.of megabytes of debug symbols and static libraries nothing here uses.

publishes, and the error names those bounds.

Update — the 90%-per-file coverage gate
The first CI run failed this gate, which I had not run locally. Closing it took
real work rather than a threshold change, and two of the things it forced are
worth calling out in review:
A defect the tests found. A parked worker whose process had died was
classified post-dispatch and the job failed terminally — even though it
provably never ran. The cause is TCP: a write into a closed peer's buffer
succeeds, so the failure only surfaces at the read, by which point the job counts
as dispatched.
Worker::has_exitednow checks before the write, turning that caseinto a transparent respawn. The pre-dispatch retry inside
dispatchwas thendead code for this transport and has been removed, with a comment explaining why.
A real worker, not a mock.
pool/fake_worker.rsre-executes the test binaryas an interpreter, so the handshake, warm reuse, recycling, backpressure, the
install pipeline, and
Engine::executeare all exercised against a genuine childprocess over a genuine socket — with no dependency on Node or Python being
installed.
Where a branch was unreachable rather than untested, I changed the code rather
than the gate:
cfg!(windows)branches became parameters (bin_dir_for,executable_name_for,windows_executable), so the Windows layout is checked on Linux instead of onno machine at all.
tested against a loopback server rather than nodejs.org or GitHub.
cache_root_undertakes the platform cache, so the last-resort fallback isordinary to exercise.
spawn_blockingjoin-failure arms collapsed into one tested helper(
blocking::run), reachable by handing it a panicking task.tracingfield expressions, whichboth covers those lines and proves a log field cannot panic.
All four contract commands plus the coverage gate now pass on all three module
repositories.
