There was a problem hiding this comment.
On Unix builds with host_env, passing a valid but blocking descriptor to signal.set_wakeup_fd() now omits the descriptor from the ValueError. PyPy's interp_signal.set_wakeup_fd and the pinned assertion in lib-python/3/test/test_signal.py:295-305 require the fd <n> must be in non-blocking mode; the fallback branch below still produces that message. Keep the original numeric fd available and interpolate it here so enabling host_env does not observably change the exception or fail that test.

github RustPython host_env crt_fd.rs Borrowed ftruncate invalid parameter handler
💡 Result:
In RustPython, the crt_fd.rs module—now located within the rustpython-host-env crate [1]—implements a C runtime file descriptor abstraction [2][3]. To handle potential crashes caused by the MSVC (Microsoft Visual C++) "invalid parameter handler" when using C runtime functions on Windows, RustPython employs a suppress_iph! macro [4]. When calling functions like ftruncate (often mapped to _chsize_s on Windows [5]) or _get_osfhandle [6], the code wraps these calls with suppress_iph! to prevent the default process crash that occurs when an invalid file descriptor is passed to these functions [4]. Regarding Borrowed types in crt_fd.rs: - The module defines a Borrowed<'_> type [5][2] that acts as an io-safe wrapper for file descriptors [5]. - In recent refactors, ftruncate has been updated to accept this Borrowed<'_> type directly [5], ensuring better integration with Rust's io-safety patterns. - Specifically, the implementation calls c::ftruncate (or the appropriate platform-specific equivalent) inside the suppress_iph! block to handle errors gracefully without triggering the global invalid parameter handler [5]. This architectural approach allows RustPython to maintain consistent file-handling logic across platforms while safely bridging to native Windows APIs [2][1].

Guard fd before constructing crt_fd::Borrowed.
ftruncate_retry is Unix-only, so the Windows CRT path does not apply here. Borrowed::borrow_raw accepts -1 under an unsafe contract; only try_borrow_raw rejects it. Use fd_borrow and convert the checked descriptor before calling the host API. crt_fd::ftruncate already wraps its C call with suppress_iph!.

On Unix host_env builds, this routes each raw OS interface name through the host helper's String result and then converts that string back to bytes. Linux permits interface names containing non-UTF-8 octets, so those names are either rejected or irreversibly replaced before fsdecode_filename_bytes can apply surrogateescape; if_nameindex() no longer round-trips with if_nametoindex(), and the analogous if_indextoname_checked(...).into_bytes() path has the same defect. Keep these Unix helper paths byte-preserving, as the prior libc implementation was.

Use a typed backend error for LZMA1 property validation.
At the pinned rustpython-common commit, encode_filter_properties returns Error::Lzma("Invalid or unsupported options") for invalid LZMA1 properties. This exact string match can fail after a dependency revision changes the wording. Expose a typed error for this case.

schannel Rust cert_context ValidUses valid_uses source CertGetEnhancedKeyUsage
💡 Result:
In the Rust schannel crate, the valid_uses method on CertContext [1][2] is a safe wrapper around the Windows API function CertGetEnhancedKeyUsage [1][3]. The valid_uses method returns a ValidUses enum [1][4], which abstracts the result of the Windows API call: - ValidUses::All: Indicates that the certificate is valid for all uses. This corresponds to the case where CertGetEnhancedKeyUsage returns a success code, but the underlying data indicates no specific restrictions (often determined by checking GetLastError for CRYPT_E_NOT_FOUND) [1][3]. - ValidUses::Oids(Vec<String>): Contains a list of Object Identifiers (OIDs) representing the specific enhanced key usages (EKUs) defined for the certificate [1][4]. Implementation Details: - The schannel crate calls CertGetEnhancedKeyUsage twice [1]. The first call is made with a null pointer to determine the required buffer size for the CTL_USAGE structure [1][3]. - After allocating a buffer of the required size, the second call retrieves the actual usage data [1]. - If the number of usage identifiers returned is zero, the code checks GetLastError [1]. If it is CRYPT_E_NOT_FOUND, it interprets the certificate as having ValidUses::All [1][3]. Otherwise, it proceeds to parse the OIDs into a vector of strings [1]. This design allows Rust developers to interact with Windows Enhanced Key Usage properties without manually managing the complex C-style memory allocation required by the CertGetEnhancedKeyUsage function [1][3].

site:learn.microsoft.com CertGetEnhancedKeyUsage dwFlags CERT_FIND_PROP_ONLY_ENHKEY_USAGE_FLAG CERT_FIND_EXT_ONLY_ENHKEY_USAGE_FLAG zero
💡 Result:
The CertGetEnhancedKeyUsage function in the Windows Cryptography API (CryptoAPI) uses the dwFlags parameter to determine whether it reports Enhanced Key Usage (EKU) information from a certificate's extensions, its extended properties, or both [1]. When dwFlags is set to zero, the function reports valid uses of a certificate based on both the EKU extension and the EKU extended property value [1]. In this case, the cUsageIdentifier member of the CERT_ENHKEY_USAGE structure will be set to the total number of valid uses determined by combining both sources [1]. The specific flags you mentioned serve to restrict the source of the EKU information: 1. CERT_FIND_EXT_ONLY_ENHKEY_USAGE_FLAG: When this flag is set, the function retrieves EKU information only from the certificate's extension [1]. 2. CERT_FIND_PROP_ONLY_ENHKEY_USAGE_FLAG: When this flag is set, the function retrieves EKU information only from the certificate's extended property value [1]. These flags are mutually exclusive in their purpose of filtering the source of the usage information, and setting either one prevents the default behavior of checking both [1].

site:learn.microsoft.com CertOpenSystemStoreW hProv 0 current user local machine store
💡 Result:
The CertOpenSystemStoreW function is a legacy, simplified API used to open common system certificate stores [1][2]. Regarding the parameters and behavior: 1. hProv Parameter: This parameter is not used in modern implementations and should always be set to 0 [1]. In older legacy environments (such as Windows XP or Windows Server 2003), it could accept a handle to a Cryptographic Service Provider (CSP); however, providing 0 is the standard practice to utilize the default provider [1]. 2. Current User vs. Local Machine: CertOpenSystemStoreW does not provide a parameter to specify whether the target store is in the current user or local machine registry location [1]. It is inherently limited in its scope. By default, CertOpenSystemStoreW typically opens the certificate store for the current user [3]. Because of this limitation, Microsoft recommends using the CertOpenStore function instead [1][4]. CertOpenStore allows for more granular control by using flags—such as CERT_SYSTEM_STORE_CURRENT_USER or CERT_SYSTEM_STORE_LOCAL_MACHINE—to explicitly define the store location [5]. In summary, for any application requiring specific control over whether the store is located in the local machine or current user hive, CertOpenStore is the required replacement for the deprecated CertOpenSystemStoreW [1].

Preserve the previous Windows certificate-store semantics.
rustpython_host_env::cert_store::enum_certificates reads both current-user and local-machine stores, while the replaced implementation reads only CERT_SYSTEM_STORE_LOCAL_MACHINE. enum_crls uses CertOpenSystemStoreW, which opens the current-user store. The host path also calls schannel::CertContext::valid_uses, which passes 0 to CertGetEnhancedKeyUsage and can combine property and extension EKUs; the previous code checked the property first and used the extension only when the property was absent. Preserve the local-machine-only scope and property-first EKU behavior, or update the dependency API and tests to define the intended change. set_default_verify_paths loads native roots separately, so these functions do not directly determine the default context trust set.

At the rustpython-host_env revision pinned by this repository, does rustpython_host_env::wmi provide exec_query_wide or another API that accepts UTF-16 units without rejecting unpaired surrogates?
💡 Result:
At the revision pinned by the repository (885cf5c2), the rustpython_host_env::wmi module does not provide an API named exec_query_wide, nor is there evidence of an API in that module specifically designed to accept UTF-16 units while allowing unpaired surrogates [1][2][3]. While RustPython has updated its Windows path handling to use WTF-8, which allows the preservation of unpaired surrogates [4], and has specific modules for WMI [1][2], the available information indicates that rustpython_host_env::wmi is a specialized module with limited functions, and no such wide-character query API was identified [3].

Validate fd before constructing crt_fd::Borrowed.
os.ftruncate and the descriptor form of os.truncate pass caller-controlled integers to ftruncate_retry. The host_env branch calls Borrowed::borrow_raw(fd) before crt_fd::ftruncate; for fd == -1, this bypasses fd_borrow, which returns EBADF through the normal Python OSError path. The unsafe constructor requires a valid descriptor, so this can violate its contract instead of producing the established error. Call fd_borrow(fd)? before the host wrapper and reuse the checked descriptor for retries.

On a free-threaded build, two threads sharing an LZMACompressor can read or write self.flushed outside the mutex that protects the backend: concurrent flushes can both pass this check, while a concurrent compress can pass it before flush finalizes the stream. PyPy's LZMACompressor.compress and flush perform the flag check/update inside self.lock; keep the flag in the same mutex-protected state so only one operation can observe and transition it.

On Windows host_env builds, opening an invalid or inaccessible certificate store now produces a message-only OSError; the analogous enum_crls branch below also discards the helper's error. The replaced implementation converted GetLastError() through os_error_win32_syscall2, so callers received the native error in .winerror and in the exception arguments. Preserve the captured Win32 error rather than synthesizing a generic exception.

There was a problem hiding this comment.
With the default Windows host_env path, a query beginning with SELECT but containing a lone surrogate now fails here with ValueError, because Python's WTF-8 string was intentionally converted to raw UTF-16 units and String::from_utf16 rejects an unpaired unit. The previous implementation, like CPython's BSTR path, passed those UTF-16 units through unchanged and let WMI determine the result, so this changes the accepted input and resulting exception. Keep a wide-string representation through the host helper instead of requiring valid Rust UTF-8.

`pyre_native::zlib` was 196 lines of `#[inline(never)]` forwarding to `rustpython_common::compression::zlib`, plus `InitError` / `DecompressError` enums copied variant-for-variant from it. Its stated purpose was to keep the engine outside the LLBC extraction, but `rustpython-common` is a git dependency, so Charon never enters it: the 849MB `pyre-interpreter.ullbc` carries 121 `rustpython_common` items, all `Foreign`, against 339 `pyre_native` items, all `Opaque`. `binascii`, `json`, `inet` and `encodings::cjk` are already consumed straight from the crate for that reason. `module/zlib` and `module/gc` now name the engine directly and pyre-native drops its `rustpython-common` dependency. `init_error` already matched the two `InitError` variants by name, so only `typeids_z_bytes` changed: it spelled its message through the adapter-only `into_message()`, which becomes the same match at the call site. `extract-llbc.py` gains a `compression` prefix, so the audit that refused a translated engine body through the `pyre_native` boundary now refuses it through the `rustpython_common` one.

`interp_zlib.py` wraps the `deflateInit` / `inflateInit` call in `compress` and `decompress` in `except ValueError` and re-raises it as `zlib.error` carrying a message of its own, while `Compress___new__` and `Decompress___new__` let the `ValueError` through. Routing both through the constructor mapping surfaced an invalid `wbits` from `zlib.compress`, and every invalid option from `zlib.decompress`, as `ValueError`. `oneshot_init_error` names the message each helper reports. The shared engine already special-cases an invalid level, so `zlib.compress(b"123", 10)` was unaffected; the snippet now also covers `zlib.compress(b"123", 6, 99)` and `zlib.decompress(b"123", -40)`, which the previous assertions missed.

RustPython #8638 publishes the engine `pyre-native/src/bz2.rs` held, with the same `Bz2Error`, `Compressor` and `Decompressor` surface, so `_bz2` changes its backend import and the native copy and the workspace `bzip2` dependency go away.

simnalamburt/xz-rs#21 is merged.

cargo metadata --locked failed in Charon/LLBC prepare because the rustpython-common lzma feature was enabled without locking its xz/xz-sys packages. Assisted-by: Claude
test_set_wakeup_fd_blocking asserts "the fd <n> must be in non-blocking mode". The host_env path dropped the descriptor. Assisted-by: Claude
Charon/LLBC extract failed because the #8655 surfaces do not provide FILTERS_MAX, is_flushed, if_nameindex_bytes, recvmsg_into, sendmsg, sendfile_no_offset, enum_certificates_local_machine, or exec_query_wide. Assisted-by: Claude
rustpython-common compiles compression::lzma only off those targets, so Charon/LLBC's wasm32 layout pass failed to resolve the backend import. Restore the xz-core engine in pyre-native for that cfg and adapt it to the shared API. Assisted-by: Claude
compression::lzma now compiles on every target. Pin rustpython to youknowone/RustPython@9c759878f (lzma-all-targets on top of #8655) and delete the pyre-native xz-core copy. Assisted-by: Claude
Move the git pin back to RustPython/RustPython at the #8664 merge. That also brings Ruff 0.16.5, so _ast convert and validate follow ThinVec, ExprCall.range_start, and DebugText accessors. Assisted-by: Claude
rustpython-ruff 0.16.5 (from #8664 / Ruff 0.16.5) declares rust-version 1.96. Charon's cargo is still 1.95.0-nightly, so extraction failed before rustc ran. Assisted-by: Claude
cargo metadata on windows-latest failed to clone rustpython-ruff 0.16.5: a flake8_builtins snapshot path exceeds MAX_PATH and libgit2 aborts with Filesystem (30). Use git.exe with core.longpaths for those jobs. Assisted-by: Claude
