Rather than going through writeHeader, which attempts to handle all formats, implement writePAXHeader, which only has an understanding of the PAX format. In PAX, the USTAR header is filled out in a best-effort manner. Thus, we change logic of formatString and formatOctal to try their best to output something (possibly truncated) in the event of an error. The new implementation of PAX headers causes several tests to fail. An investigation into the new output reveals that the new behavior is correct, while the tests had actually locked in incorrect behavior before. A dump of the differences is listed below (-before, +after): << writer-big.tar >> This change is due to fact that we changed the Header.Devminor to force the tar.Writer to choose the GNU format over the PAX one. The ability to control the output is an open issue (see #18710). - 00000150 00 30 30 30 30 30 30 30 00 00 00 00 00 00 00 00 |.0000000........| + 00000150 00 ff ff ff ff ff ff ff ff 00 00 00 00 00 00 00 |................| << writer-big-long.tar>> The previous logic generated the GNU magic values for a PAX file.

The tests for error scenarios were done by manually checking error strings. Improved them by checking the actual error type instead of just the string. Printing the actual error in case of failure instead of a generic string. Also added a new scenario with both an invalid byte and an invalid length string to verify that the length is checked first before doing any computation.

Errors returned by Reader contain the line where the Reader originally encountered the error. This can be suboptimal since that line does not always correspond with the line the current record/field started at. This can easily happen with LazyQuotes as seen in #19019, but also happens for example when a quoted fields has no closing quote and the parser hits EOF before it finds another quote. When this happens finding the erroneous field can be somewhat complicated and time consuming, and in most cases it would be better to report the line where the record started. This change updates Reader to keep track of the line on which a record begins and uses it for errors instead of the current line, making it easier to find errors. Although a user-visible change, this should have no impact on existing code, since most users don't explicitly work with the line in the error and probably already expect the new behaviour.

All the BSDs and Solaris support the utimensat syscall, but Darwin doesn't. Account for that by adding the //sys lines not to syscall_bsd.go but the individual OS's syscall_*.go files and implement utimensat on Darwin as just returning ENOSYS, such that UtimesNano will fall back to use utimes as it currently does unconditionally. This also adds the previously missing utimensat syscall number for FreeBSD and Dragonfly.

Currently we only support finding symbols in the VDSO using the old DT_HASH. These days everything uses DT_GNU_HASH instead. To keep up with the times and future-proof against DT_HASH disappearing from the VDSO in the future, this commit adds support for DT_GNU_HASH and prefers it over DT_HASH. Tested by making sure it found a DT_GNU_HASH section and all of the expected symbols in it, and then disabling the DT_GNU_HASH path and making sure the old DT_HASH path still found all of the symbols. Fixes #19649.

Increases performance of FieldsFunc by recording the start and end of the fields in an array. The first 32 fields are saved in a pre-allocated array on the stack. This avoids the old behavior of iterating over the input string two times but uses more allocations when more than 32 fields are encountered. Additionally code for handling non-ASCII containing strings from Fields is removed and replaced by a call to the new faster FieldsFunc function. Overall this still leads to a slowdown for Fields on non-ASCII strings while speeding up Fields in general. name old time/op new time/op delta Fields/ASCII/16 116ns ± 5% 115ns ± 5% ~ (p=0.480 n=10+10) Fields/ASCII/256 765ns ± 1% 761ns ± 2% ~ (p=0.171 n=10+10) Fields/ASCII/4096 12.5µs ± 1% 12.7µs ± 1% +1.82% (p=0.000 n=10+10) Fields/ASCII/65536 226µs ± 1% 226µs ± 2% ~ (p=0.739 n=10+10) Fields/ASCII/1048576 5.12ms ± 1% 5.12ms ± 1% ~ (p=0.696 n=8+10) Fields/Mixed/16 172ns ± 1% 233ns ± 1% +35.90% (p=0.000 n=9+10) Fields/Mixed/256 1.18µs ± 2% 2.45µs ± 1% +107.47% (p=0.000 n=10+10) Fields/Mixed/4096 20.3µs ± 1% 43.1µs ± 2% +112.41% (p=0.000 n=10+10) Fields/Mixed/65536 364µs ± 1% 704µs ± 1% +93.56% (p=0.000 n=9+10) Fields/Mixed/1048576 7.07ms ± 2% 13.34ms ± 4% +88.83% (p=0.000 n=10+10) FieldsFunc/ASCII/16 274ns ± 1% 188ns ± 3% -31.44% (p=0.000 n=10+10) FieldsFunc/ASCII/256 3.69µs ± 1% 2.06µs ± 2% -44.26% (p=0.000 n=10+10) FieldsFunc/ASCII/4096 59.9µs ± 1% 35.3µs ± 2% -41.10% (p=0.000 n=10+10) FieldsFunc/ASCII/65536 958µs ± 1% 567µs ± 1% -40.82% (p=0.000 n=10+9) FieldsFunc/ASCII/1048576 16.3ms ± 2% 11.0ms ± 3% -32.52% (p=0.000 n=10+10) FieldsFunc/Mixed/16 309ns ± 1% 213ns ± 0% -30.98% (p=0.000 n=10+6) FieldsFunc/Mixed/256 3.83µs ± 1% 2.14µs ± 1% -44.01% (p=0.000 n=10+10) FieldsFunc/Mixed/4096 66.2µs ± 2% 37.8µs ± 1% -42.85% (p=0.000 n=10+10) FieldsFunc/Mixed/65536 1.09ms ± 1% 0.63ms ± 1% -42.73% (p=0.000 n=10+10) FieldsFunc/Mixed/1048576 18.6ms ± 3% 12.0ms ± 2% -35.50% (p=0.000 n=10+10) Fixes #17856 Fixes #19789 Change-Id: I9f5a560e534566fd81963651f342c8f44cfb0469 Reviewed-on: https://go-review.googlesource.com/42810Reviewed-by:

Rather than going through the complicated logic of writeHeader, implement a writeUSTARHeader that only knows about the USTAR format. This makes the logic much easier to reason about since you only need to be concerned about USTAR and not all the subtle differences between USTAR, PAX, and GNU. We seperate out the logic in writeUSTARHeader into templateV7Plus and writeRawHeader since the planned implementations of writePAXHeader and writeGNUHeader will use them.

The dieFromSignal runtime function attempts to forward crashing signals to a signal handler registered before the runtime was initialized, if any. However, on Darwin, a special signal handler trampoline is invoked, even for non-Go signal handlers. Clear the crashing signal's handlingSig entry to ensure sigtramp forwards the signal. Fixes the darwin/386 builder.

According to http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_key_create.html, pthread_key_create return an error number which is greater than or equal to 0. I don't know the scenario that pthread_setspecific would fail, but also don't know the future. Add some error handlings just in case.

$ go tool -h says: For more about each tool command, see 'go tool command -h'. but it was suggested to change the suggestion to say: see 'go doc command' In #18313. That would work for every tool except dist, which has no doc.go. This change adds a doc.go file to cmd/dist.

Currently all trace slices get shifted to start at time 0. This makes it very difficult to find specific points in time unless they fall in the first slice. For example, right now when you click "View trace (6.005646218s-8.155419698s)" on the trace tool's main page, the trace view puts the first event in that slice at time 0. If you're looking for something that happened at time 7s, you have to look at time 0.9943537s in the trace view. And if you want to subtract times taken from different slices, you have to figure out what those time really correspond to. Fix this by telling the trace viewer not to shift the times when it imports the trace. In the above example, this makes the view of that second trace slice start at time 6.005646218s, so you don't have to do any gymnastics to find or calculate times in later slices.

This updates the HTML served for the trace viewer to follow the latest revision of the example from the upstream tracing project. The main thing this adds is CSS for the trace viewer (which was actually in the example at the originally referenced revision, so I'm not sure why it got dropped). In particular, this expands the trace viewer to use the entire browser client area, which fixes several problems with the current page: 1. The details pane gets cut off at a strange place and can get a scroll bar even if there's plenty of room below it on the page. This fixes the bottom of the details pane to the bottom of the window. 2. If the track view is very tall (lots of procs), there's no way to view the top tracks and the details pane at the same time. This fixes this problem by limiting the height of the track view to something less than the height of the window so it gets a scroll bar of its own if necessary. 3. Dragging the divider between the track pane and the details pane actually moves the bottom of the details pane without moving the divider. Fixing the height of the trace viewer fixes this problem.

_main has an early check to verify if a binary is statically or dynamically linked that depends on R0 being zero. R0 is not guaranteed to be zero at that point and this was breaking Go on Alpine for ppc64le.
