In CL 206757 I added a log.Printf to identify when GOROOT is not read-only. However, it interacts badly with test sharding in the builders: the log is repeated for every shard. Since the log statement isn't particularly high-value, just remove it.

Some, but not all, architectures mix in OS-provided random seeds when initializing the fastrand state. The others have TODOs saying we need to do the same. Lift that logic up in the architecture-independent part, and use memhash to mix the seed instead of a simple addition. Previously, dumping the fastrand state at initialization would yield something like the following on linux-amd64, where the values in the first column do not change between runs (as thread IDs are sequential and always start at 0), and the values in the second column, while changing every run, are pretty correlated: first run: 0x0 0x44d82f1c 0x5f356495 0x44f339de 0xbe6ac92a 0x44f91cd8 0x1da02dbf 0x44fd91bc 0x7cd59254 0x44fee8a4 0xdc0af6e9 0x4547a1e0 0x3b405b7e 0x474c76fc 0x9a75c013 0x475309dc 0xf9ab24a8 0x4bffd075 second run: 0x0 0xa63fc3eb 0x5f356495 0xa6648dc2 0xbe6ac92a 0xa66c1c59 0x1da02dbf 0xa671bce8 0x7cd59254 0xa70e8287 0xdc0af6e9 0xa7129d2e 0x3b405b7e 0xa7379e2d 0x9a75c013 0xa7e4c64c 0xf9ab24a8 0xa7ecce07 With this change, we get initial states that appear to be much more unpredictable, both within the same run as well as between runs: 0x11bddad7 0x97241c63 0x553dacc6 0x2bcd8523 0x62c01085 0x16413d92 0x6f40e9e6 0x7a138de6 0xa4898053 0x70d816f0 0x5ca5b433 0x188a395b 0x62778ca9 0xd462c3b5 0xd6e160e4 0xac9b4bd 0xb9571d65 0x597a981d Change-Id: Ib22c530157d74200df0083f830e0408fd4aaea58 Reviewed-on: https://go-review.googlesource.com/c/go/+/203439 Run-TryBot: Keith Randall <khr@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

We use the typedValue map to prevent showing typed variables and constants from appearing in the VARIABLES/CONSTANTS section because they will be anyways shown in the TYPES section for that type. However, when a type is unexported, but the variable is exported, then unconditionally setting it to true in the map suppresses it from being shown in the VARIABLES section. Thus, we set the variable or constant in the typedValue map only when the type name is exported.

TLS 1.3, which requires RSA-PSS, is now enabled without a GODEBUG opt-out, and with the introduction of Certificate.SupportedSignatureAlgorithms (#28660) there is a programmatic way to avoid RSA-PSS (disable TLS 1.3 with MaxVersion and use that field to specify only PKCS#1 v1.5 SignatureSchemes). This effectively reverts 0b3a57b5, although following CL 205061 all of the signing-side logic is conveniently centralized in signatureSchemesForCertificate.

Now that we have a full implementation of the logic to check certificate compatibility, we can let applications just list multiple chains in Certificates (for example, an RSA and an ECDSA one) and choose the most appropriate automatically. NameToCertificate only maps each name to one chain, so simply deprecate it, and while at it simplify its implementation by not stripping trailing dots from the SNI (which is specified not to have any, see RFC 6066, Section 3) and by not supporting multi-level wildcards, which are not a thing in the WebPKI (and in crypto/x509). The performance of SupportsCertificate without Leaf is poor, but doesn't affect current users. For now document that, and address it properly in the next cycle. See #35504. While cleaning up the Certificates/GetCertificate/GetConfigForClient behavior, also support leaving Certificates/GetCertificate nil if GetConfigForClient is set, and send unrecognized_name when there are no available certificates.

This refactors a lot of the certificate support logic to make it cleaner and reusable where possible. These changes will make the following CLs much simpler. In particular, the heavily overloaded pickSignatureAlgorithm is gone. That function used to cover both signing and verifying side, would work both for pre-signature_algorithms TLS 1.0/1.1 and TLS 1.2, and returned sigalg, type and hash. Now, TLS 1.0/1.1 and 1.2 are differentiated at the caller, as they have effectively completely different logic. TLS 1.0/1.1 simply use legacyTypeAndHashFromPublicKey as they employ a fixed hash function and signature algorithm for each public key type. TLS 1.2 is instead routed through selectSignatureScheme (on the signing side) or isSupportedSignatureAlgorithm (on the verifying side) and typeAndHashFromSignatureScheme, like TLS 1.3. On the signing side, signatureSchemesForCertificate was already version aware (for PKCS#1 v1.5 vs PSS support), so selectSignatureScheme just had to learn the Section 7.4.1.4.1 defaults for a missing signature_algorithms to replace pickSignatureAlgorithm. On the verifying side, pickSignatureAlgorithm was also checking the public key type, while isSupportedSignatureAlgorithm + typeAndHashFromSignatureScheme are not, but that check was redundant with the one in verifyHandshakeSignature. There should be no major change in behavior so far. A few minor changes came from the refactor: we now correctly require signature_algorithms in TLS 1.3 when using a certificate; we won't use Ed25519 in TLS 1.2 if the client didn't send signature_algorithms; and we don't send ec_points_format in the ServerHello (a compatibility measure) if we are not doing ECDHE anyway because there are no mutually supported curves. The tests also got simpler because they test simpler functions. The caller logic switching between TLS 1.0/1.1 and 1.2 is tested by the transcript tests.

This CL is based on work started by Joe Tsai in CL 94855. It's rebased on top of the latest master branch, and addresses various code review comments and findings from attempting to use the original CL in practice. The testing package documents a naming convention for examples so that documentation tools can associate them with: • a package (Example or Example_suffix) • a function F (ExampleF or ExampleF_suffix) • a type T (ExampleT or ExampleT_suffix) • a method T.M (ExampleT_M or ExampleT_M_suffix) This naming convention is in widespread use and enforced via existing go vet checks. This change adds first-class support for classifying examples to go/doc, the package responsible for computing package documentation from Go AST. There isn't a way to supply test files to New that works well. External test files may have a package name with "_test" suffix, so ast.NewPackage may end up using the wrong package name if given test files. A workaround is to add test files to *ast.Package.Files after it is returned from ast.NewPackage: pkg, _ := ast.NewPackage(fset, goFiles, ...) for name, f := range testGoFiles { pkg.Files[name] = f } p := doc.New(pkg, ...) But that is not a good API. After nearly 8 years, a new entry-point is added to the go/doc package, the function NewFromFiles. It accepts a Go package in the form of a list of parsed Go files (including _test.go files) and an import path. The caller is responsible with filtering out files based on build constraints, as was the case before with New. NewFromFiles computes package documentation from .go files, extracts examples from _test.go files and classifies them. Examples fields are added to Package, Type, and Func. They are documented to only be populated with examples found in _test.go files provided to NewFromFiles. The new behavior is: 1. NewFromFiles computes package documentation from provided parsed .go files. It extracts examples from _test.go files. 2. It assigns each Example to corresponding Package, Type, or Func. 3. It sets the Suffix field in each example to the suffix. 4. Malformed examples are skipped. This change implements behavior that matches the current behavior of existing godoc-like tools, and will enable them to rely on the logic in go/doc instead of reimplementing it themselves.
