runner.Execute was not filtering ~/.pmg/bin from the environment
passed to child processes. This caused two bugs:
1. Sandboxed commands (bubblewrap) inherited the unfiltered PATH,
so child processes resolved package manager binaries to the shim
instead of the real binary, causing "file not found" errors.
2. Direct pmg invocations (pmg npm install) would spawn subprocess
that find the shim in PATH, causing infinite recursion (shim →
pmg → shim → pmg) until the system runs out of OS threads.
The proxy flow already filtered the environment via setupEnvForProxy
and FilterPMGFromEnv. This applies the same filtering to the
non-proxy execute path.
* feat: add FilterPMGFromPath utility for PATH shim recursion prevention
* feat: add FilterPMGFromEnv to filter PATH from env slices
* feat: filter ~/.pmg/bin from PATH in proxy subprocess env
* feat: add PathExport method to Shell interface for shim PATH integration
* feat: add ShimManager for PATH shim install/remove lifecycle
* feat: wire ShimManager into setup commands with --use-aliases fallback
* refactor: add DefaultShimConfig helper to reduce setup boilerplate
* fix: resolve real binary path to prevent shim double-invocation
exec.CommandContext resolves the binary using the current process PATH,
which still contains ~/.pmg/bin. This caused pmg to launch the shim
instead of the real package manager, resulting in a second pmg instance
with its own proxy — producing duplicate error messages and wasted work.
ResolveRealBinary searches a filtered PATH (without ~/.pmg/bin) to find
the real package manager binary before execution.
* fix: resolve real binary in runner.Execute and expand path resolution tests
Ensure guard mode and proxy skip paths also resolve through
ResolveRealBinary to prevent infinite shim recursion. Add table-driven
tests covering error cases, multi-binary PATH, and PATH restoration.
* fix: handle error return values from os.Setenv and file Close calls
Address errcheck lint failures: check os.Setenv returns in
ResolveRealBinary, and check f.Close/tempFile.Close in ShimManager.
* feat: auto-migrate shell aliases to PATH shims on setup install
When running `pmg setup install`, detect existing shell aliases and
automatically remove them before installing shims. Existing users
get a seamless migration with no extra flags or commands needed.
* fix: update E2E test to verify shim installation instead of alias RC file
Replace the .pmg.rc file check with assertions that ~/.pmg/bin/ exists
and contains executable shim scripts for npm and pip.

Replace the .pmg.rc file check with assertions that ~/.pmg/bin/ exists

* feat: install both aliases and shims for full coverage
Aliases win in interactive shells (including venvs), shims catch
non-interactive contexts (IDEs, CI, subprocesses). Remove --use-aliases
flag and migration logic since both are always installed together.
Update E2E to verify all shim scripts and alias RC file.
* feat: address review feedback for shim implementation
- Install both aliases and shims together for full coverage
- Move homeDir resolution into NewDefaultShimManager (internal concern)
- Add mutex to ResolveRealBinary to guard against concurrent PATH mutation
- Use filepath.SplitList for platform-correct PATH splitting
- Add ResolveRealBinary to runner.Execute and proxy flow to prevent
shim recursion in all execution paths
- Remove print side-effects from ShimManager.Remove
- Update E2E to verify all shim scripts and alias RC file
- Expand ResolveRealBinary tests with table-driven cases
* fix: restore errcheck handling and add concurrency test for ResolveRealBinary
- Restore proper defer with log.Warnf for PATH restoration in ResolveRealBinary
- Restore errcheck handling for f.Close() and tempFile.Close() in ShimManager
- Add explanatory comment for ResolveRealBinary call in proxy_flow
- Add TestResolveRealBinaryConcurrent to verify mutex guards concurrent access
* feat: skip shell integration on Windows with informative warning
On Windows, pmg setup install now writes only the config file and
prints a warning that shell aliases and PATH shims require WSL.

- Replace nested policies map with flat skip_commands map in ProxyConfig
- Make skip_commands dependent on install_only being enabled
- Move proxy configuration docs from proxy.md to proxy-mode.md
- Update config template and tests for new schema
* feat: add ProxyConfig struct with per-PM skip_commands and legacy fallback
* feat: consolidate proxy config into structured section with backward compat
Replaces flat proxy_mode/proxy_install_only keys with a structured proxy
section supporting per-package-manager skip_commands. Legacy keys are
respected via fallback when user's config lacks the new proxy section.
Removes deprecated experimental_proxy_mode config and flag.
* fix: env var resolution for nested config keys and deduplicate skip command matching
- Add "." to "_" in Viper env key replacer so nested keys like
sandbox.enabled resolve from PMG_SANDBOX_ENABLED (was silently broken)
- Export IsFirstNonFlagArgInList and remove duplicate from proxy_flow.go
- Add table-driven tests for skip command matching with real-world cases
- Remove redundant env var test
* docs: update proxy configuration and env var documentation
Update config.md env var table to reflect new proxy.enabled and
proxy.install_only keys. Add proxy configuration section to proxy.md
covering config structure, per-PM skip commands, CLI flags, and env vars.
* fix: legacy fallback precedence
ConfigureSandbox was only triggered by IsInstallationCommand(), missing
update commands (npm update, pnpm update, etc.) that pull new versions
and run postinstall scripts. Use MayDownloadPackages() as the sandbox
signal so all package-downloading commands are sandboxed.

* feat: Show cooldown report for pinned version installs
When a user installs a package with an explicit version (e.g.
npm install foo@1.2.3) and that version falls within the dependency
cooldown window, the cooldown block is now recorded and shown in the
report. Previously, the report only appeared when ALL versions of a
package were in cooldown (remaining == 0), causing pinned version
installs to fail with a confusing "version not found" error from the
package manager instead of a clear cooldown explanation.
Introduces InterceptorContext to carry per-execution data (pinned
versions) from the CLI command through the interceptor layer, keeping
it separate from long-lived dependencies like the analyzer and cache.
* fix: Normalize PyPI pinned version keys for cooldown lookup
CLI-provided package names (e.g. Flask_Cors) don't match the
URL-parsed form (flask-cors). Normalize keys once at construction
time so cooldown lookups match correctly.
* fix: Handle dots in PyPI package name normalization per PEP 503
denormalizePyPIPackageName already documented [-_.] replacement but
only handled underscores. Now also replaces dots with hyphens so
names like zope.interface match the URL-parsed form zope-interface.
* refactor: Extract shared cooldown stats recording into helper
Deduplicate identical stats-recording blocks from npm_cooldown.go
and pypi_cooldown.go into recordCooldownStats in cooldown.go.
* fix: Distinguish explicit version pins from auto-resolved versions
PyPI parsers resolve all packages to concrete versions (even without
a user-specified constraint), so HasVersion() was always true. Add
IsExplicitVersion to PackageInstallTarget, set it only when the user
provided an explicit constraint. Use it in proxy_flow.go to avoid
false pinned-version cooldown reports.
* feat: Add proxy_install_only config to restrict proxy to download commands
Introduces proxy_install_only (default: false) which, when enabled,
skips the proxy for package manager commands that do not download
packages (e.g. npm ls, pip list), avoiding unnecessary MITM overhead.
- Add ProxyInstallOnly to Config and config template
- Add IsKnownDownloadCommand / MayDownloadPackages to ParsedCommand
- Add DownloadCommands to npm and pypi PM configs covering update,
ci, audit, dlx, exec, x, download, run and equivalents per PM
- Extract shared runner.Execute used by both proxy flow and guard
- Proxy flow short-circuits to runner.Execute for non-download commands
when proxy_install_only=true
* refactor: Inject CommandExecutor into guard to fix dependency direction
guard depended on internal/runner, which inverted the intended layer
hierarchy. Now guard defines a CommandExecutor function type and accepts
it as a constructor argument. internal/flows (the composition root)
creates the executor closure wrapping runner.Execute and injects it,
keeping guard free of internal/ dependencies.
* refactor: Invert proxy_install_only logic to use known non-download commands
Replace the DownloadCommands allowlist (opt-in, fail-open) with a
NonDownloadCommands denylist (opt-out, fail-safe). The proxy now runs
for all commands except those explicitly known to not download packages.
Unknown or future package manager subcommands default to running with
the proxy.
Includes script runners (run, start, test, stop, restart) that can spin
up local servers — setting proxy env vars on these breaks them without
providing any security benefit. Also covers removal commands and local
operations that never contact the registry.
* fix: Support PMG_* env vars regardless of config file state
AutomaticEnv only resolves env vars for keys Viper already knows about
via AllKeys(). When a key is absent from the config file (commented out,
new key added after last setup, or no config file at all), Viper had no
knowledge of it and silently skipped the env var.
Fix by registering all Config struct fields as Viper defaults via
reflection (using mapstructure tags) before reading the config file.
This ensures PMG_* env vars work in all cases.
Precedence: cobra flags > env vars > config file > defaults.
SetDefault is used (not Set) so env vars and config file can still
override the Go defaults freely.
Tests added covering all precedence levels including the key-absent-
from-config-file case that was the original bug report.
* fix: Only check first non-flag arg against NonDownloadCommands
Scanning all args caused false proxy bypasses when package names or
script arguments matched a NonDownloadCommands entry. For example:
- npm exec test → "test" matched, proxy incorrectly skipped
- npm update config → "config" matched, proxy skipped
- npm publish --tag version → "version" matched, proxy skipped
Fix by checking only the first non-flag argument (the subcommand).
If it is not in NonDownloadCommands we break immediately, so trailing
args never influence the classification. Applied to all four parsers:
npm, pip/pip3, uv, and poetry.
Regression tests added for the false positive cases.
* refactor: Replace reflection-based Viper defaults with embedded template
Load the embedded config template as the Viper base so all keys are
registered upfront, enabling PMG_* env vars to work regardless of
whether a key exists in the user's config file.
* fix: Restore trusted_packages template entry and revert DefaultConfig change
* docs: Document environment variable overrides for config keys
* update npm test cmd
* refactor: extract shared non-download command detection helper
Replaces duplicated first-non-flag-arg detection loops in npm.go and
pypi.go (pip + poetry parsers) with a shared isFirstNonFlagArgInList
helper in packagemanager.go.

* feat: Add dependency cooldown for npm packages
Strip recently-published package versions from npm registry metadata
responses so npm's resolver naturally falls back to older versions.
Overrides the Accept header to force full packument responses (which
include the "time" field needed for publish-date checks).
Reports cooldown blocks only when all versions are stripped (remaining == 0),
matching npm's --min-release-age behavior for silent fallback.
* fix: Report oldest version in cooldown block (shortest wait)
When all versions are blocked by cooldown, report the oldest version
since it exits the cooldown window first — giving the user the
shortest wait time instead of the longest.
* fix: Handle resp.Body.Close error return for errcheck linter
* test: Add dependency cooldown assertions to template config tests
* fix: config template for dependency cooldown
* fix: Prevent npm from caching cooldown-stripped metadata responses
* fix: Restore body on ReadAll failure and log Close errors in response modifier
* fix: Close response body before replacing to prevent connection leak
* fix: Correct daysLeft ceiling math and update ContentLength on error recovery
* fix: Clear Status on status code change and update ContentLength in modifier error path
* refactor: address review comments on dependency cooldown PR
- Make NpmCooldownHandler and constructor package-private
- Pass cooldown days as parameter instead of reading config internally
- Convert standalone functions to methods on npmCooldownHandler
- Set Accept-Encoding: identity to prevent gzip responses breaking JSON parsing
- Return 503 with descriptive message when upstream body read fails
* fix: log errors in stripCooldownVersions instead of swallowing them
* fix: Config preserve fallback defaults
* fix: Code review fixes
* fix: correct cooldown tip to show wait time instead of incorrect trusted_packages advice
* fix: prevent integer overflow in cooldown duration calculation with large days values
* refactor: deduplicate CooldownBlock into internal/models, fix misleading variable names
- Move CooldownBlock struct to internal/models to eliminate duplication
between proxy/interceptors and internal/ui packages
- Simplify proxy_flow.go by using direct assignment instead of field copy
- Rename latestStripped/latestDate to oldestVer/oldestDate for clarity

When users have HTTP_PROXY/HTTPS_PROXY set in their shell (e.g. corporate
proxy), PMG's upstream transport routes all traffic through that external
proxy — including requests to localhost/127.0.0.1. The external proxy
cannot reach the user's loopback, causing EFAULT/ConnectionRefused errors.
This adds loopback bypass in two places:
- Proxy upstream transport skips external proxy for localhost/127.0.0.1/::1
- Child process env gets NO_PROXY so proxy-aware libs (axios) skip PMG's
proxy for loopback addresses
Fixes#193

The spinner goroutine was writing carriage-return + status text to
os.Stdout every 100ms. In the non-interactive TTY path, the child
process also writes directly to os.Stdout, causing both writers to
race on the same file descriptor. The \r emitted by the spinner
resets the cursor to column 0 mid-line, corrupting and truncating
the child process output.
Fix by writing all spinner/status output to os.Stderr, which is the
standard Unix convention for diagnostic and status messages. This is
also consistent with how progress.go and ShowWarning already behave.
