2025-07-08cmd/go: disable support for multiple vcs in one moduleRoland Shoemaker
Removes the somewhat redundant vcs.FromDir, "allowNesting" argument, which was always enabled, and disallow multiple VCS metadata folders being present in a single directory. This makes VCS injection attacks much more difficult. Also adds a GODEBUG, allowmultiplevcs, which re-enables this behavior. Thanks to RyotaK (https://ryotak.net) of GMO Flatt Security Inc for reporting this issue.

2025-05-21runtime/trace: add the flight recorderCarlos Amedee
This change adds the flight recorder to the trace package. Flight recording is a technique in which trace data is kept in a circular buffer and can be flushed upon request. The implementation will be added in follow-up CLs. The flight recorder has already been implemented inside of the golang.org/x/exp/trace package. This copies the current implementation and modifies it to work within the runtime/trace package. The changes include: This adds the ability for multiple consumers (both the execution tracer and the flight recorder) to subscribe to tracing events. This change allows us to add multiple consumers without making major modifications to the runtime. Future optimizations are planned for this functionality. This removes the use of byte readers from the process that parses and processes the trace batches. This modifies the flight recorder to not parse out the trace clock frequency, since that requires knowledge of the format that's unfortunate to encode in yet another place. Right now, the trace clock frequency is considered stable for the lifetime of the program, so just grab it directly from the runtime. This change adds an in-band end-of-generation signal to the internal implementation of runtime.ReadTrace. The internal implementation is exported via linkname to runtime/trace, so the flight recorder can identify exactly when a generation has ended. This signal is also useful for ensuring that subscribers to runtime trace data always see complete generations, by starting or stopping data streaming only at generation boundaries.

Previously the common Config.mutualVersion() code prioritized the selected version based on the provided peerVersions being sent in peer preference order. Instead we would prefer to see TLS 1.3 used whenever it is supported, even if the peer would prefer an older protocol version. This commit updates mutualVersions() to implement this policy change. Our new behaviour matches the behaviour of other TLS stacks, notably BoringSSL, and so also allows enabling the IgnoreClientVersionOrder BoGo test that we otherwise must skip.

2025-05-21runtime: use cgroup CPU limit to set GOMAXPROCSMichael Pratt
This CL adds two related features enabled by default via compatibility GODEBUGs containermaxprocs and updatemaxprocs. On Linux, containermaxprocs makes the Go runtime consider cgroup CPU bandwidth limits (quota/period) when setting GOMAXPROCS. If the cgroup limit is lower than the number of logical CPUs available, then the cgroup limit takes precedence. On all OSes, updatemaxprocs makes the Go runtime periodically recalculate the default GOMAXPROCS value and update GOMAXPROCS if it has changed. If GOMAXPROCS is set manually, this update does not occur. This is intended primarily to detect changes to cgroup limits, but it applies on all OSes because the CPU affinity mask can change as well. The runtime only considers the limit in the leaf cgroup (the one that actually contains the process), caching the CPU limit file descriptor(s), which are periodically reread for updates. This is a small departure from the original proposed design. It will not consider limits of parent cgroups (which may be lower than the leaf), and it will not detection cgroup migration after process start. We can consider changing this in the future, but the simpler approach is less invasive; less risk to packages that have some awareness of runtime internals. e.g., if the runtime periodically opens new files during execution, file descriptor leak detection is difficult to implement in a stable way.

Currently, the `source` method in `slog.Record` is not accessible to custom handlers, requiring developers to re-implement logic for retrieving source location information.

2025-05-05net,os: support converting between *os.File and net.Conn on Windowsqmuntal
The runtime poller and os.NewFile recently gained support for disassociating the handle from the runtime poller IOCP (see CL 664455). This was the main blocker for allowing the conversion between *os.File and net.Conn. Implementing the conversion is now trivial. The only remaining work, implemented in this CL, is improving os.NewFile to also support socket handles and updating some build tags so that Windows can share almost the same net's File implementation as Unix. There is one important limitation, though: the duplicated socket handle returned by the various File methods in the net package is not usable on other process. If someone needs to pass a socket handle to another process, they should manually call the WSADuplicateSocket Windows API passing the process ID of the target process. Fixes #9503. Fixes #10350. Updates #19098.

2025-04-18regexp/syntax: recognize category aliases like \p{Letter}Russ Cox
The Unicode specification defines aliases for some of the general category names. For example the category "L" has alias "Letter". The regexp package supports \p{L} but not \p{Letter}, because there was nothing in the Unicode tables that lets regexp know about Letter. Now that package unicode provides CategoryAliases (see #70780), we can use it to provide \p{Letter} as well. This is the only feature missing from making package regexp suitable for use in a JSON-API Schema implementation. (The official test suite includes usage of aliases like \p{Letter} instead of \p{L}.) For better conformity with Unicode TR18, also accept case-insensitive matches for names and ignore underscores, hyphens, and spaces; and add Any, ASCII, and Assigned. Fixes #70781.

2025-04-04os: support overlapped IO with NewFileqmuntal
The runtime/poll package has just gained support for overlapped IO, see CL 660595 and CL 661955. The only remaining piece was making it visible to user code via os.NewFile. Some of the poll.FD.Init responsibility has been moved to os.NewFile to avoid unnecessary syscalls for the common case of using os.Open, os.Create, os.OpenFile, and os.Pipe, where we know that the file is not opened for overlapped IO. Some internal/poll tests have been moved to the os package to exercise public APIs rather than internal ones. The os.NewFile function definition has been moved into an OS-agnostic file to avoid having duplicated documentation and ensure that the caller is aware of its behavior across all platforms. Closes #19098.
