2023-10-06encoding/json: fix appendCompact escapingAlexander Yastrebov
CL 469555 changed Compact to use append instead of bytes.Buffer. appendCompact iterates over input src slice and performs escaping of certain characters. To optimize copying it does not copy characters one by one but keeps track of the start offset of the data to copy when it reaches next character to escape or the end of the input. This start offset may become greater than input character offset so copying of preceding data should check this condition. CL 469555 removed boundary checks for copying data preceding escaped characters and this change restores them.

2023-08-25encoding/json: modernize testsJoe Tsai
There are no changes to what is being tested. No test cases were removed or added. Changes made: * Use a local implementation of test case position marking. See #52751. * Use consistent names for all test tables and variables. * Generally speaking, follow modern Go style guide for tests. * Move global tables local to the test function if possible. * Make every table entry run in a distinct testing.T.Run. The purpose of this change is to make it easier to perform v1-to-v2 development where we want v2 to support close to bug-for-bug compatibility when running in v1 mode. Annotating each test case with the location of the test data makes it easier to jump directly to the test data itself and understand why this particular case is failing. Having every test case run in its own t.Run makes it easier to isolate a particular failing test and work on fixing the code until that test case starts to pass again. Unfortunately, many tests are annotated with an empty name. An empty name is better than nothing, since the testing framework auto assigns a numeric ID for duplicate names. It is not worth the trouble to give descriptive names to each of the thousands of test cases.

2023-08-23encoding/json: encode \b and \f as '\b' and '\f' in JSON stringsJoe Tsai
According to RFC 8259, there are exactly 5 control characters that have a shorter escape sequence than the generic \uXXXX format. Over the years, we added ad-hoc support for the short sequences: * https://go.dev/cl/4678046 supports \r and \n * https://go.dev/cl/162340043 supports \t This CL completes the set by supporting \b and \f. This may change the encoding of strings in relatively rare cases, but is a permissible change since the Go 1 compatibility document does not guarantee that "json" produces byte-for-byte identical outputs. In fact, we have made even more observable output changes in the past such as with https://go.dev/cl/30371 which changes the representation of many JSON numbers. This change is to prepare the path forward for a potential v2 "json" package, which has more consistent encoding of JSON strings.

2023-08-19encoding: optimize growth behavior in Encoding.AppendDecodeJoe Tsai
The Encoding.DecodedLen API only returns the maximum length of the expected decoded output, since it does not know about padding. Since we have the input, we can do better by computing the input length without padding, and then perform the DecodedLen calculation as if there were no padding. This avoids over-growing the destination slice if possible. Over-growth is still possible since the input may contain ignore characters like newlines and carriage returns, but those a rarely encountered in practice.

A negative rune (other than NoPadding) makes no semantic sense. Doing so relies on integer overflow of converting a rune to a byte and would thus be equivalent to passing the positive byte value of byte(padding). This may cause existing code to panic. An alternative is treat negative runes as equivalent to NoPadding. However, the code already panics to report erroneous padding values, so this is in line with the existing API.

2023-08-14encoding/json: declare hex as a constJes Cok
hex is in fact immutable, declare it as a const to avoid accidental modification, also for consistency with other packages.

2023-08-07all: add a few more godoc linksDaniel Martí
Over the past few months as I read the standard library's documentation I kept finding spots where godoc links would have helped me. I kept adding to a stash of changes to fix them up bit by bit. The stash has grown big enough by now, and we're nearing a release, so I think it's time to merge to avoid git conflicts or bit rot. Note that a few sentences are slightly reworded, since "implements the Fooer interface" can just be "implements [Fooer]" now that the link provides all the context needed to the user.

2023-06-27encoding: document that base32 and base64 do not use UTF-8Joe Tsai
The invention of base32 and base64 predates the invention of UTF-8 and was never meant to output valid UTF-8. By default, the output is always valid ASCII (and thus valid UTF-8) except when the user specifies an alphabet or padding value that is larger than '\x7f'. If that is done, then the exact byte symbol is used rather than the UTF-8 encoding.
