Since switching to SSA, the only remaining use for the Ullman field was in tracking whether or not an expression contained a function call. Give it a new name and encode it in our fancy new bitset field. Passes toolstash-check.

This gives accurate line numbers to inlined functions from another package. Previously AST nodes from another package would get the line number of the import statement for that package. The following benchmark results show how the size of package export data is impacted by this change.

The meaning of Version=1 was overloaded: it was reserved for file name symbols (to avoid conflicts with non-file name symbols), but was also used to mean "give me a fresh version number for this symbol." With the new inlining tree, the same file name symbol can appear in multiple entries, but each one would become a distinct symbol with its own version number. Now, we avoid duplicating symbols by using Version=0 for file name symbols and we avoid conflicts with other symbols by prefixing the symbol name with "gofile..".

Without this, literals keep their original source positions through inlining, which results in strange jumps in line numbers of inlined function bodies. By copying literals, inlining can update their source position like other nodes. Fixes #15453.

In order to generate accurate tracebacks, the runtime needs to know the inlined call stack for a given PC. This creates two tables per function for this purpose. The first table is the inlining tree (stored in the function's funcdata), which has a node containing the file, line, and function name for every inlined call. The second table is a PC-value table that maps each PC to a node in the inlining tree (or -1 if the PC is not the result of inlining). To give the appearance that inlining hasn't happened, the runtime also needs the original source position information of inlined AST nodes. Previously the compiler plastered over the line numbers of inlined AST nodes with the line number of the call. This meant that the PC-line table mapped each PC to line number of the outermost call in its inlined call stack, with no way to access the innermost line number. Now the compiler retains line numbers of inlined AST nodes and writes the innermost source position information to the PC-line and PC-file tables. Some tools and tests expect to see outermost line numbers, so we provide the OutermostLine function for displaying line info. To keep track of the inlined call stack for an AST node, we extend the src.PosBase type with an index into a global inlining tree. Every time the compiler inlines a call, it creates a node in the global inlining tree for the call, and writes its index to the PosBase of every inlined AST node. The parent of this node is the inlining tree index of the call. -1 signifies no parent. For each function, the compiler creates a local inlining tree and a PC-value table mapping each PC to an index in the local tree. These are written to an object file, which is read by the linker. The linker re-encodes these tables compactly by deduplicating function names and file names. This change increases the size of binaries by 4-5%. For example, this is how the go1 benchmark binary is impacted by this change: section old bytes new bytes delta .text 3.49M ± 0% 3.49M ± 0% +0.06% .rodata 1.12M ± 0% 1.21M ± 0% +8.21% .gopclntab 1.50M ± 0% 1.68M ± 0% +11.89% .debug_line 338k ± 0% 435k ± 0% +28.78% Total 9.21M ± 0% 9.58M ± 0% +4.01% Updates #19348.

Currently we scan the finalizers queue both during concurrent mark and during mark termination. This costs roughly 20ns per queued finalizer and about 1ns per unused finalizer queue slot (allocated queue length never decreases), which can drive up STW time if there are many finalizers. However, we only add finalizers to this queue during sweeping, which means that the second scan will never find anything new. Hence, we can fix this by simply not scanning the finalizers queue during mark termination. This brings the STW time under the 100µs goal even with 1,000,000 queued finalizers. Fixes #18869.

A value is "volatile" if it is a pointer to the argument region on stack which will be clobbered by function call. This is used to make sure the value is safe when inserting write barrier calls. The writebarrier pass can tell whether a value is such a pointer. Therefore no need to mark it when building SSA and thread this information through. Passes "toolstash -cmp" on std. Updates #17583.

This changes the decoder's behaviour when there is stray/extra data found after an image is decompressed (e.g., data sub-blocks after an LZW End of Information Code). Instead of raising an error, we silently skip over such data until we find the end of the image data marked by a Block Terminator. We skip at most one byte as sample problem GIFs exhibit this property. GIFs should not have and do not need such stray data (though the specification is arguably ambiguous). However GIFs with such properties have been seen in the wild. Fixes #16146 Change-Id: Ie7e69052bab5256b4834992304e6ca58e93c1879 Reviewed-on: https://go-review.googlesource.com/37258Reviewed-by:

p.m is accessed in WriteTo without holding p.mu. Move the access inside the critical section.

There's no good reason to exclude it and it only makes the code more complicated and less consistent. Having it in the list provides an easy way to detect if a package uses operations from package unsafe.

The old code may have reported different errors given an erroneous package depending on the order in which files were parsed concurrently. The new code always reports errors in "file order", independent of processing order. Also: - simplified parsing code and internal concurrency control - removed -seq flag which didn't really add useful functionality Change-Id: I18e24e630f458f2bc107a7b83926ae761d63c334 Reviewed-on: https://go-review.googlesource.com/37655Reviewed-by:

If I put a 10 millisecond sleep at testHookWaitResLoop, before the big select in (*persistConn).roundTrip, two flakes immediately started happening, TestTransportBodyReadError (#19231) and TestTransportPersistConnReadLoopEOF. The problem was that there are many ways for a RoundTrip call to fail (errors reading from Request.Body while writing the response, errors writing the response, errors reading the response due to server closes, errors due to servers sending malformed responses, cancelations, timeouts, etc.), and many of those failures then tear down the TCP connection, causing more failures, since there are always at least three goroutines involved (reading, writing, RoundTripping). Because the errors were communicated over buffered channels to a giant select, the error returned to the caller was a function of which random select case was called, which was why a 10ms delay before the select brought out so many bugs. (several fixed in my previous CLs the past few days). Instead, track the error explicitly in the transportRequest, guarded by a mutex. In addition, this CL now: * differentiates between the two ways writing a request can fail: the io.Copy reading from the Request.Body or the io.Copy writing to the network. A new io.Reader type notes read errors from the Request.Body. The read-from-body vs write-to-network errors are now prioritized differently. * unifies the two mapRoundTripErrorFromXXX methods into one mapRoundTripError method since their logic is now the same. * adds a (*Request).WithT(*testing.T) method in export_test.go, usable by tests, to call t.Logf at points during RoundTrip. This is disabled behind a constant except when debugging. * documents and deflakes TestClientRedirectContext I've tested this CL with high -count values, with/without -race, with/without delays before the select, etc. So far it seems robust. Fixes #19231 (TestTransportBodyReadError flake) Updates #14203 (source of errors unclear; they're now tracked more) Updates #15935 (document Transport errors more; at least understood more now) Change-Id: I3cccc3607f369724b5344763e35ad2b7ea415738 Reviewed-on: https://go-review.googlesource.com/37495 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

Using GetClientCertificate with the http client is currently completely broken because inside the transport we clone the tls.Config and pass it off to the tls.Client. Since tls.Config.Clone() does not pass forward the GetClientCertificate field, GetClientCertificate is ignored in this context.
