* log: Do not pad too long values * log: gofmt
docs: change http to https on links in log/README.md
* log: fix formatting of big.Int The implementation of formatLogfmtBigInt had two issues: it crashed when the number was actually large enough to hit the big integer case, and modified the big.Int while formatting it. * log: don't call FormatLogfmtInt64 for int16 * log: separate from decimals back, not front Co-authored-by: Péter Szilágyi <[email protected]>
This modifies the order of Lock() defer Unlock() to follow the more typically used pattern.
* log: allow tabs in log messages This fixes a regression where panic reports in RPC handlers were quoted because they contain tab characters. * Update format.go
Add usage examples

These changes improves the performance of the non-coloured terminal formatting, _quite a lot_. ``` name old time/op new time/op delta TerminalHandler-8 10.2µs ±15% 5.4µs ± 9% -47.02% (p=0.008 n=5+5) name old alloc/op new alloc/op delta TerminalHandler-8 2.17kB ± 0% 0.40kB ± 0% -81.46% (p=0.008 n=5+5) name old allocs/op new allocs/op delta TerminalHandler-8 33.0 ± 0% 5.0 ± 0% -84.85% (p=0.008 n=5+5) ``` I tried to _somewhat_ organize the commits, but the it might still be a bit chaotic. Some core insights: - The function `terminalHandler.Handl` uses a mutex, and writes all output immediately to 'upstream'. Thus, it can reuse a scratch-buffer every time. - This buffer can be propagated internally, making all the internal formatters either write directly to it, - OR, make use of the `tmp := buf.AvailableBuffer()` in some cases, where a byte buffer "extra capacity" can be temporarily used. - The `slog` package uses `Attr` by value. It makes sense to minimize operating on them, since iterating / collecting into a new slice, iterating again etc causes copy-on-heap. Better to operate on them only once. - If we want to do padding, it's better to copy from a constant `space`-buffer than to invoke `bytes.Repeat` every single time.
…m#28622) This change - Removes interface `log.Format`, - Removes method `log.FormatFunc`, - unexports `TerminalHandler.TerminalFormat` formatting methods (renamed to `TerminalHandler.format`) - removes the notion of `log.Lazy` values The lazy handler was useful in the old log package, since it could defer the evaluation of costly attributes until later in the log pipeline: thus, if the logging was done at 'Trace', we could skip evaluation if logging only was set to 'Info'. With the move to slog, this way of deferring evaluation is no longer needed, since slog introduced 'Enabled': the caller can thus do the evaluate-or-not decision at the callsite, which is much more straight-forward than dealing with lazy reflect-based evaluation. Also, lazy evaluation would not work with 'native' slog, as in, these two statements would be evaluated differently: ```golang log.Info("foo", "my lazy", lazyObj) slog.Info("foo", "my lazy", lazyObj) ```
slog.SetDefault has undesirable side effects. It also sets the default logger destination, for example. So we should not call it by default in init.
