2020-08-27Fix vfs2 pipe behavior when splicing to a non-pipe.Dean Deng
Fixes *.sh Java runtime tests, where splice()-ing from a pipe to /dev/zero would not actually empty the pipe. There was no guarantee that the data would actually be consumed on a splice operation unless the output file's implementation of Write/PWrite actually called VFSPipeFD.CopyIn. Now, whatever bytes are "written" are consumed regardless of whether CopyIn is called or not. Furthermore, the number of bytes in the IOSequence for reads is now capped at the amount of data actually available. Before, splicing to /dev/zero would always return the requested splice size without taking the actual available data into account. This change also refactors the case where an input file is spliced into an output pipe so that it follows a similar pattern, which is arguably cleaner anyway. Updates #3576.

2020-08-27Improve type safety for socket optionsGhanan Gowripalan
The existing implementation for {G,S}etSockOpt take arguments of an empty interface type which all types (implicitly) implement; any type may be passed to the functions. This change introduces marker interfaces for socket options that may be set or queried which socket option types implement to ensure that invalid types are caught at compile time. Different interfaces are used to allow the compiler to enforce read-only or set-only socket options. Fixes #3714. RELNOTES: n/a PiperOrigin-RevId: 328832161

2020-08-27Add function to get error from a tcpip.EndpointGhanan Gowripalan
In an upcoming CL, socket option types are made to implement a marker interface with pointer receivers. Since this results in calling methods of an interface with a pointer, we incur an allocation when attempting to get an Endpoint's last error with the current implementation. When calling the method of an interface, the compiler is unable to determine what the interface implementation does with the pointer (since calling a method on an interface uses virtual dispatch at runtime so the compiler does not know what the interface method will do) so it allocates on the heap to be safe incase an implementation continues to hold the pointer after the functioon returns (the reference escapes the scope of the object). In the example below, the compiler does not know what b.foo does with the reference to a it allocates a on the heap as the reference to a may escape the scope of a. ``` var a int var b someInterface b.foo(&a) ``` This change removes the opportunity for that allocation.

2020-08-26Make flag propagation automaticFabricio Voznika
Use reflection and tags to provide automatic conversion from Config to flags. This makes adding new flags less error-prone, skips flags using default values (easier to read), and makes tests correctly use default flag values for test Configs. Updates #3494 PiperOrigin-RevId: 328662070
