We reset global buffer only if its pos != 0. We ought to do it always, but queue it only if pos != 0. This is a latent bug. Currently it does not fire because whenever we create a global buffer, we increment pos.

Change it to "invalid pointer found on stack" to emphasize that it's a pointer on the stack that's invalid. Updates #16948.

The maximum input plaintext for GCM is 64GiB - 64. Since the GCM interface is one-shot, it's very hard to hit this in Go (one would need a 64GiB buffer in memory), but we should still enforce this limit. Thanks to Quan Nguyen for pointing it out.

RFC 2616, section 14.10 says: >>> HTTP/1.1 proxies MUST parse the Connection header field before a message is forwarded and, for each connection-token in this field, remove any header field(s) from the message with the same name as the connection-token. Connection options are signaled by the presence of a connection-token in the Connection header field, not by any corresponding additional header field(s), since the additional header field may not be sent if there are no parameters associated with that connection option. <<< The same requirement was included in RFC 7230, section 6.1.

While it was previously explicitly documented that "the default Source" is safe for concurrent use, a careless reader can interpret that as meaning "the implementation of the Source interface created by functions in this package" rather than "the default shared Source used by top-level functions". Be explicit that the Source returned by NewSource is not safe for use by multiple goroutines. Fixes #3611.

In Go 1.0, the Config struct consisted only of exported fields. In Go 1.1, it started to grow private, uncopyable fields (sync.Once, sync.Mutex, etc). Ever since, people have been writing their own private Config.Clone methods, or risking it and doing a language-level shallow copy and copying the unexported sync variables. Clean this up and export the Config.clone method as Config.Clone. This matches the convention of Template.Clone from text/template and html/template at least.

The tar.Reader guarantees stickiness of errors. Ensuring this property means that the methods of Reader need to be consistent about whose responsibility it is to actually ensure that errors are sticky. In this CL, we make it only the responsibility of the exported methods (Next and Read) to store tr.err. All other methods just return the error as is. As part of this change, we also check the error value of mergePAX (and test that it properly detects invalid PAX files). Since the value of mergePAX was never used before, we change it such that it always returns ErrHeader instead of strconv.SyntaxError. This keeps it consistent with other usages of strconv in the same tar package.

Instead of saving all pragmas and processing them after parsing is finished, process them immediately during scanning like the current lexer does. This is a bit unfortunate because it means we can't use syntax.ParseFile to concurrently parse files yet, but it fixes how we report syntax errors in the presence of //line pragmas. While here, add a bunch more gcCompat entries to syntax/parser.go to get "go build -toolexec='toolstash -cmp' std cmd" passing. There are still a few remaining cases only triggered building unit tests, but this seems like a nice checkpoint.

Major reorganization of the crc32 code: - The arch-specific files now implement a well-defined interface (documented in crc32.go). They no longer have the responsibility of initializing and falling back to a non-accelerated implementation; instead, that happens in the higher level code. - The non-accelerated algorithms are moved to a separate file with no dependencies on other code. - The "cutoff" optimization for slicing-by-8 is moved inside the algorithm itself (as opposed to every callsite). Tests are significantly improved: - direct tests for the non-accelerated algorithms. - "cross-check" tests for arch-specific implementations (all archs). - tests for misaligned buffers for both IEEE and Castagnoli. Fixes #16909. Change-Id: I9b6dd83b7a57cd615eae901c0a6d61c6b8091c74 Reviewed-on: https://go-review.googlesource.com/27935Reviewed-by:

cmd/go links mingwex and mingw32 libraries to every package it builds. This breaks when 2 different packages call same gcc standard library function pow. gcc linker appends pow implementation to the compiled package, and names that function "pow". But when these 2 compiled packages are linked together into the final executable, linker complains, because it finds two "pow" functions with the same name. This CL stops linking of mingwex and mingw32 during package build - that leaves pow function reference unresolved. pow reference gets resolved as final executable is built, by having both internal and external linker use mingwex and mingw32 libraries.

The goal for these examples is to show how to mirror the functionality of the sha256sum Unix utility, a common checksumming tool, using the Go standard library. Add a newline at the end of the input, so users will get the same output if they type `echo 'hello world' | sha256sum`, since the builtin shell echo appends a newline by default. Also use hex output (instead of the shorter base64) since this is the default output encoding for shasum/sha256sum.
