* fix(python): split PIP_TRUSTED_HOST by whitespace for multiple hosts
When PIP_TRUSTED_HOST contains multiple space-separated hostnames, the
whole string was passed as a single --trusted-host argument
(--trusted-host "host1 host2") rather than one flag per host. This
matches pip's documented PIP_TRUSTED_HOST convention by emitting a
separate --trusted-host for each host, mirroring the existing
pip_extra_index_url handling.
Fixes WIN-2077

* fix(python): use shell word-splitting for nsjail trusted-host args
Address review feedback: the previous tr/sed pipeline only split on
single spaces, diverging from the Rust split_whitespace() paths. Repeated
or leading/trailing spaces produced empty --trusted-host flags and
tab-separated hosts were not split. Use an unquoted for-loop over
$TRUSTED_HOST so the shell's own IFS word-splitting handles arbitrary
whitespace and skips empty fields, matching the non-nsjail paths.

* feat: add sandboxed docker v2 runtime via '# docker <image>'
Run a container image as a subprogram of the job's own nsjail sandbox:
extract the image rootfs with podman (rootless) and run it chrooted inside the
job's nsjail, so the container inherits the job's confinement and is safe under
nsjail / for untrusted code. Selected by '# docker <image>'; a bare '# docker'
keeps the v1 (dind) path untouched.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat: default to daemonless docker (drop dind from compose, allow docker on cloud)
docker-compose no longer ships the dind sidecar (v2 is daemonless: podman + nsjail
in the worker); removed the dind service, DOCKER_HOST env, depends_on and volume.
Removed the language-picker guard that blocked Docker scripts on the multi-tenant
platform, now that v2 makes docker safe to run sandboxed.

* feat: select sandboxed container via # sandbox <image>; add pull policy + size guards
- Surface moved from '# docker <image>' to '# sandbox <image>' (groups under the
sandbox annotation; '# docker' stays v1-only, '# sandbox' stays nsjail-bash).
- SANDBOX_IMAGE_PULL_POLICY (default 'newer') so moving tags don't go stale.
- SANDBOX_IMAGE_MAX_SIZE_MB rejects oversized images before extraction.
- SANDBOX_IMAGE_CACHE_MAX_MB best-effort LRU eviction of podman's image store.

* feat(sandbox): support # volume, honor nsjail tmp instance settings, v2 docker template
- Thread shared_mount into the sandbox container nsjail config so '# volume' mounts
(and the same-worker /tmp/shared folder) apply inside the container.
- Use resolve_nsjail_tmp_mount_block for the container's /tmp so it honors the same
nsjail_tmp_backing / nsjail_tmpfs_size_mb instance settings as other nsjail jobs.
- docker-compose comment + the editor's Docker template now use '# sandbox <image>'.

Convert SANDBOX_IMAGE_* from worker env vars to DB-backed instance settings
(sandbox_image_max_size_mb, sandbox_image_cache_max_mb, sandbox_image_pull_policy),
hot-reloaded via the same mechanism as nsjail_tmpfs_size_mb and configurable in

Two new instance settings:
- sandbox_image_default_registry: prepended to unqualified image refs (alpine ->
<registry>/alpine); fully-qualified refs untouched.
- sandbox_registry_auth: docker/podman auth.json blob written to a per-job authfile

authfile is created 0600 atomically (no world-readable window); add a
registry_qualified table test + a non-ASCII proto_str case.

* fix(sandbox): P0 — deliver image env via nsjail envar:, never the launcher process env
CI review (P0): the image's OCI Env (attacker-controlled keys+values) was applied to
the nsjail launcher process via .envs(), so a hostile image could set LD_PRELOAD/
LD_LIBRARY_PATH/LD_AUDIT on nsjail itself and execute code as the worker outside the
jail. Now the image env is rendered as proto-escaped 'envar:' directives (child-only)
and nsjail's process env carries only windmill-trusted keys (reserved vars + proxy).
Also: warn instead of silently bypassing the size guard on inspect failure; reset the
eviction guard via a Drop guard (no stuck flag on panic/early-return). +render_envars test.

* fix(sandbox): P0 symlink-write escape via rootfs script; P1 redact registry-auth logging
CI review:
- P0 (Codex): the body was written into the image-controlled rootfs as
.windmill_docker_main.sh via write_file (follows symlinks) — a hostile image could
plant that path as a symlink to a host file and capture the worker's write before
nsjail starts. Now the body is passed straight to 'sh -c <body> sh <args>'; no file
is written into the rootfs at all.
- P1 (Codex): sandbox_registry_auth flowed through the generic setting loader which
logs the value (raw auth.json credentials). Replaced with a secret-aware reload that
loads directly and logs only a redacted 'configured=' message.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(sandbox): redact sandbox_registry_auth in instance-settings write log too
The settings API also logs 'Set global setting <key> to <value>' via format_setting_value;
add sandbox_registry_auth to SENSITIVE_SETTINGS so the credential is redacted there as
well as on reload.
* fix(sandbox): don't silently disable cache eviction on podman images parse error
Re-review (cubic/Claude P2): serde_json::from_slice(...).unwrap_or_default() meant any
parse hiccup (e.g. podman omitting Size/Created via omitempty for a zero value, or
schema drift) silently degraded to an empty Vec and disabled eviction with no log.
Now Size/Created are #[serde(default)] (a missing omitempty key -> 0, not a whole-array
parse failure) and a real parse error warns + breaks instead of being swallowed.

#9393 added `--compile-bytecode` to the uv pip install run inside the
python download nsjail. uv spawns a Python interpreter that compiles .py
files with parallelism scaling to the host CPU count, opening many file
descriptors at once. The download nsjail capped `rlimit_nofile` at 64,
which is exhausted on high-core machines, failing every install with
"Failed to bytecode-compile ... Too many open files (os error 24)".
Low-core VMs never hit the cap, so this surfaced only as a regression on
larger workers after upgrading.
Raise `rlimit_nofile` to 10000, matching the runtime configs
(run.python3 / run.ansible) that already use that value.
Fixes WIN-2009

Python jobs under nsjail experience slow imports (~465ms for `import
requests`) because dependency directories are mounted read-only. Without
pre-compiled `.pyc` files, Python recompiles `.py` source to bytecode
in-memory on every import in every fresh nsjail process, paying the cost
repeatedly.
Add `--compile-bytecode` to both `uv pip install` invocations (the
Rust-driven install in python_executor.rs and the nsjail
download_deps.py.sh script) so `.pyc` files are generated at install
time and available at runtime even through read-only mounts. The files
are included in both the local cache and S3 piptar uploads.
The flag is supported by the uv version (0.9.24+) shipped in the
Dockerfile. The existing `__pycache__` skip only filters top-level dirs
for dedup logic, not subdirs within packages, so there is no conflict.

* feat(nsjail): optional disk-backed /tmp via instance setting
* test(nsjail): unit-test tmp mount resolver and narrow visibility
* refactor(nsjail): switch tmp backing to select + conditional UI
* ui(nsjail): make tmpfs the visible default in /tmp backing select
* fix(nsjail): refuse preexisting jail_tmp to block symlink escape
* fix(nsjail): allow jail_tmp reuse on sequential nsjail calls
Codex flagged that python/ruby/rust executors invoke nsjail twice per
job_dir (install then run). The previous resolver treated any preexisting
jail_tmp as hostile and silently fell back to tmpfs on the second call,
so disk-backed mode never reached the main script run for those langs.
Use symlink_metadata().is_dir() to distinguish a real directory left by
an earlier call in the same job_dir (safe to reuse) from a symlink or
other entity (still refused, as the codebase-tar escape requires).
Also loosen the frontend visibility predicate: only hide nsjail settings
when job_isolation is explicitly 'none' or 'unshare', so deployments
that enable nsjail via DISABLE_NSJAIL=false with no DB setting can
still see the controls.
* feat(nsjail): make tmpfs size configurable via instance setting
Adds a new `nsjail_tmpfs_size_mb` instance setting that overrides the
size of the `/tmp` tmpfs mount inside the nsjail sandbox across all
languages. When unset, the existing per-language defaults (500MB or
800MB) continue to apply, so no behavior change for existing
deployments.
The setting is exposed under Settings → Jobs and is read at job
execution time, so changes take effect on the next job without a
restart.

* refactor(nsjail): unify default tmpfs size to 800MB
Previously each executor passed its own per-language default (500MB or

behavior is consistent across languages.

The download.ruby config render runs inside a sync closure passed to

feature. Resolve the size once before the closure and capture the

* docs(nsjail): rename resolver to *_bytes and clarify fallback
Addresses CI review feedback:
- Rename `resolve_nsjail_tmpfs_size` to `resolve_nsjail_tmpfs_size_bytes`
so the returned unit is unambiguous at the call site (cubic P2).
- Fix the `NSJAIL_TMPFS_SIZE_MB` doc comment that still said "per-language
default" — there is no per-language fallback anymore, all unset
values resolve to the unified 800MB `DEFAULT_NSJAIL_TMPFS_SIZE_BYTES`
(codex/pi P2).
- Expand the resolver doc to call out that `Some(0)` and negative values
also fall back, since the match arm is `Some(mb) if mb > 0`.
No behavior change.

* docs(nsjail): explain why per-file /etc resolver binds are load-bearing
The explicit /etc/hosts, /etc/resolv.conf and /etc/hostname binds look
like removable duplication of the read-only /etc bind above them. They
are not: on Kubernetes those files are separate kubelet bind-mounts on
top of /etc and nsjail's read-only remount is non-recursive, so without
these shadow binds they stay writable and a job can persist cross-tenant
DNS poisoning for the pod lifetime. Comment guards against a future
"dedup cleanup" silently reintroducing the vulnerability.

* fix: unsuspend and fail parent when WAC child push fails
Previously if a child push failed mid-batch, the parent remained
suspended with suspend = num_steps but fewer children, hanging until
the 14-day timeout. Now the push loop catches errors and unsuspends
the parent before returning the error.
Also adds source hash validation: if the script content changes between
replays, the job fails with a clear error instead of silently feeding
stale checkpoint data into wrong steps.

* test: add exhaustive edge case tests for WAC v2 SDK
fix: make TS task wrapper non-async to fix unawaited task flush
The async wrapper caused microtask-based thenable auto-resolution that
fired .then() and threw StepSuspend before _flushPending() could capture
unawaited steps — making the flush mechanism completely broken. Now the
thenable is returned directly without async wrapping. Backward compatible
with v1 (all code paths still return awaitables).
Tests added (59 TS + 66 Python) covering: full sequential lifecycle,
step after parallel, parallel after parallel, conditional on step result,
empty/single-task workflows, 10+ steps, falsy value preservation, inline
steps, mixed step/task, unawaited flush, child mode with parallel,
key determinism, large parallel groups, and complex mixed patterns.

* fix: atomic checkpoint updates to prevent parallel child race condition
Replace read-modify-write pattern in handle_wac_child_completion with
atomic SQL operations:
- completed_steps merged via jsonb_set(... || jsonb_build_object(...))
so concurrent children on different workers don't overwrite each other
- suspend counter decremented atomically with RETURNING to determine
"all done" condition (instead of checking completed_steps in memory)
- suspend_until cleared in the same atomic decrement statement
Before this fix, two parallel children completing simultaneously could
both load the same checkpoint, each add their step, and save — the
second write would overwrite the first, silently losing a child result
and leaving the parent suspended forever.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: cancel already-pushed children on partial WAC dispatch failure
When pushing child jobs sequentially, if pushing child N fails, children
1..N-1 are already running. Previously the error handler only unsuspended
the parent, leaving orphaned children that would complete and corrupt the
checkpoint state (decrementing suspend on an already-unsuspended parent,
potentially causing duplicate step execution on re-run).
Now on partial failure:
1. Cancel all already-pushed children (prevents them from completing
and corrupting checkpoint state)
2. Clear pending_steps from checkpoint (so parent doesn't think
children are outstanding on re-run)
3. Then unsuspend parent (so the error propagates)

* fix: skip WAC duration write and child check for non-WAC parents
The duration write to workflow_as_code_status was running for every
non-flow child with a parent (error handlers, success handlers,
run_script children), even though it was only intended for WAC jobs.
Add WHERE workflow_as_code_status IS NOT NULL to skip non-WAC parents
entirely. Piggyback RETURNING pending_steps.job_ids on the same query
so WAC v2 child completion needs zero extra DB round-trips on the
success path.

* fix: seed child checkpoint in same transaction as push
The child checkpoint insert was happening before the child job was
pushed, violating the FK constraint on v2_job_status. Move it into

* fix: set running=false when WAC parent suspends for child dispatch
The parent job kept running=true after suspending, so workers wouldn't
pick it up when children completed and suspend reached 0. The parent
only advanced when the zombie job detector reset it (~90s). Now the
dispatch suspend sets running=false so the parent is immediately
eligible for pickup.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: WAC parent suspend/unsuspend lifecycle
Keep running=true when suspending the parent so the normal pull query
(WHERE running=false) never picks it up. Keep suspend_until non-null
when decrementing suspend to 0 so the suspended pull query
(WHERE suspend_until IS NOT NULL AND suspend<=0) picks it up.
Previously: setting running=false caused infinite restart loops because
the normal pull query has no suspend check and would immediately re-pick
the parent. Clearing suspend_until on the last child prevented the
suspended pull from ever seeing it, requiring the 90s zombie detector.

- Add approval/sleep resume injection to Python executor
- Fix TS SDK concurrency_limit mapping (was reading wrong property)
- Namespace error marker as __wmill_error to avoid user data collision
- Wrap child completion SQL in transaction for atomicity
- Decrement suspend even when step key is missing (prevents hang)
- Expand TASK_RE to handle export const, let, var, generics
- Validate step key uniqueness before dispatch
- Log warning on checkpoint deserialization failure
- Remove unimplemented delete_after_use from SDKs
- Add TaskError exception class to Python SDK with diagnostic context
- Fix extra positional args handling and add functools.wraps
- Improve getParamNames to handle typed/destructured params

* fix: auto-heal corrupted python runtime cache on remote workers
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Revert "fix: auto-heal corrupted python runtime cache on remote workers"
This reverts commit 0ea013a554.
* feat: make WINDMILL_DIR configurable via environment variable
Allow users to configure the base directory for Windmill's tmp/cache files
via the WINDMILL_DIR env var (default: /tmp/windmill). This fixes Python
runtime cache corruption on RHEL systems where systemd-tmpfiles-clean
removes files from /tmp.
Converts TMP_DIR (renamed to WINDMILL_DIR) and all derived cache directory
constants from compile-time const &str (concatcp!) to runtime lazy_static
String values.

* fix: restore Windows /tmp path translation in go and bun executors
The Windows path translation replaces /tmp with the Windows temp dir
(e.g. C:\tmp) before normalizing slashes. Without this, the default
WINDMILL_DIR=/tmp/windmill produces paths without a drive letter on
Windows.

* fix(python): fix uv can't find ssl certificates
- Add `PY_NATIVE_CERT` flag, forces UV to use native tls
- Rename `PIP_INDEX_CERT` to `PY_INDEX_CERT`
- Rename `PIP_TRUSTED_HOST` to `PY_TRUSTED_HOST`
For backwards compatibility PIP* variables are still accessible
* feat(python): add `custom_wheels` directory to PYTHONPATH
Add global directory by path `<CACHE_DIR>/python_xyz/custom_wheels`
For example for scripts running python 3.11, in every execution
`<CACHE_DIR>/python_311/custom_wheels` will be accessible and all wheels placed there could be imported and used.
This is usefull for preinstalling wheels before runtime
* Make it work with Nsjail
* Rework and make custom_wheels optional
* Remove `create_dir_all` from imports
* Use sync version of metadata
* Rename `custom_wheels` to `global-site-packages`
* feat: Handle `pip install` by `uv`
Dirty and untested, but already something working
* Integrate with NSJAIL and prepare fallbacks
* Refactor fallback
no_uv disable compile and install
where no_uv_install and no_uv_compile are a bit more specific
* Remove `--disable-pip-version-check`
Reason:
warning: pip's `--disable-pip-version-check` has no effect
* Fix backend compilation error
* Pip fallback overwrite UV's cache
* Initially refactor cache (No S3)
* Support S3
* Remove unused import
* Handle flags for NSJAIL
* Return deleted flag
* Remove verbose mode and enable link-mode=copy
* Granural migration of lockfiles
Before i realized we dont need it :)
* Initial draft (not-working)
* Add fallback
* Fix bug preventing uv from installing deps
'\n' - Love it
* Add verbosity indicator
* Iterate on feature
- Added instance python version
- Rework logic

* bun: Migrate to bun.lock
(In backwards compatible way)
Read more: https://bun.sh/blog/bun-lock-text-lockfile
* Clean up
* More clean up
* Mount bun.lock to jailed process
* Revert solution with Mutex
* Implement valid.windmill logic
* Remove unused import
* valid.windmill -> .valid.windmill
Just like .lock
* Dont delete wheels if cancelled/failed
Now we dont clean up requirement folder if it was failed.
This way we can fully utilize uv's flock system.
Also if we left wheel dir, but it was partially filled (resulting to invalid wheel)
we use --reinstall flag in order to overwrite any content of wheels
* Add comment
* Add --reinstall to nsjail
* Add csharp stuff and merge after the rewrite
* Add csharp, boilerplate + minimal execution
* Add initial parser
* Frontend + wasm export of the tree sitter parser
* Arg spread and use cache
* More types and req parsing
* Add logo
* Parse async and void to fit the wrapper to the main sig
* Csharp editor resource and var buttons
* Lockfile generation
* Add default parsing using serde_json::from_str
* Update init code for c#
* Nsjail for c#
* Remove c_variadic feature
* Remove unused imports
* Add c_variadic only for wasm32 assembly
* Fix c# test
* Add dotnet to the images
* Update dockerfiles
* Update dockerfile again
* Touch Dockerfile

* Add opt mount in nsjail
* Update ee repo ref
* Add csharp to backend image for tests
* Add setting to set nuget package
* Windows compatibility
* Disable csharp test
* ADd feature flag
* feat: Handle `pip install` by `uv`
Dirty and untested, but already something working

* Update docker-image.yml
* Add --link-mode=copy and remove -v
* Fix NSJAIL INDEX_URL
* Fix flock and windows
* Update python_executor.rs
* Remove line from Dockerfile
We dont need it and to trigger build
* fixing for windows
* Dont pin python to specific version
* Change TMP for windows
* Revert docker-image.yml
* Disable UV for ansible
Will be enabled later.
Needs proper testing and its better to split onto 2 PRs with first modifying python and second ansible
