Updating each call in place broke when there were multiple cgo calls used as arguments to another cgo call where some required rewriting. Instead, rewrite calls to strings via the existing mangling mechanism, and only substitute the top level call in place.

For many build systems, modular static analysis is most conveniently implemented by saving analysis facts (which are analogous to export data) in an additional section in the archive file, similar to __PKGDEF. See golang.org/x/tools/go/analysis for an overview. Because such sections are not object files, the linker must not attempt to link them. This change causes the linker to skip special sections whose name does not end with .o (and is short enough not to be truncated).

Follow CL 146020 and enable RemoveAll based on Unlinkat and Openat on freebsd. Since the layout of syscall.Stat_t changes in FreeBSD 12, Fstatat needs a compatibility wrapper akin to Fstatat in x/sys/unix. See CL 138595 and CL 136816 for details.

readContinuedLineSlice intends to buffer a continued line of text, where a continued line can continue through newlines so long as the next line begins with a space or tab. The current optimization is to not try to buffer and build a line if we immediately see that the next line begins with an ASCII character. This adds avoiding copying the line if we see that the next line is \n or \r\n as well. Notably, headers always end in \r\n\r\n. In the general, well formatted header case, we can now avoid ever allocating textproto.Reader's internal reusable buf.

Divide the "empty" slot state into two, "emptyOne" and "emptyRest". emptyOne means just that slot is empty. emptyRest means all subsequent slots in that bucket are empty and the overflow pointer is nil. When scanning a bucket, we can often stop at emptyRest, reducing the total work we have to do. (This is similar to how tombstones work in open addressing.) Ideally on delete we have to figure out whether to zero the slot with an emptyOne or emptyRest marker. For now, we choose the safe but non-optimal choice. (Fix in subsequent CL?) This is a simpler CL than some others we've tried, including my CL sequence 11835[5-8] and Ilya's CL 115616.

I am working on a TLS server program, which issues new TLS certificates on demand. The new certificates will be added into tls.Config.Certificates. BuildNameToCertificate will be called to refresh the name table afterwards. This change will reduce some workload on existing certificates. Note that you can’t modify the Certificates field (or call BuildNameToCertificate) on a Config in use by a Server. You can however modify an unused Config that gets cloned in GetConfigForClient with appropriate locking.

On unix systems, long enough path names will fail when performing syscalls like `Lstat`. The current RemoveAll uses several of these syscalls, and so will fail for long paths. This can be risky, as it can let users "hide" files from the system or otherwise make long enough paths for programs to fail. By using `Unlinkat` and `Openat` syscalls instead, RemoveAll is safer on unix systems. Initially implemented for linux, darwin, dragonfly, netbsd and openbsd. Not yet implemented on freebsd due to fstatat 64-bit inode compatibility issues. Fixes #27029 Co-authored-by:

For moves >8,<16 bytes, do a move using non-overlapping loads/stores if it would require no more instructions. This helps a bit with the case when the move is from a static constant, because then the code to materialize the value being moved is smaller.

This lets []byte->string conversions which are used as arguments to strings.IndexByte and friends have their backing store allocated on the stack. It only prevents allocation when the string is small enough (32 bytes), so it isn't perfect. But reusing the []byte backing store directly requires a bunch more compiler analysis (see #2205 and related issues). Fixes #25864.

This change scavenges the largest spans before growing the heap for physical pages to "make up" for the newly-mapped space which, presumably, will be touched. In theory, this approach to scavenging helps reduce the RSS of an application by marking fragments in memory as reclaimable to the OS more eagerly than before. In practice this may not necessarily be true, depending on how sysUnused is implemented for each platform. Fixes #14045.

Currently, we mark a whole span as sysUsed before trimming, but this unnecessarily tells the OS that the trimmed section from the span is used when it may have been scavenged, if s was scavenged. Overall, this just makes invocations of sysUsed a little more fine-grained. It does come with the caveat that now heap_released needs to be managed a little more carefully in allocSpanLocked. In this case, we choose to (like before this change) negate any effect the span has on heap_released before trimming, then add it back if the trimmed part is scavengable. For #14045.
