In some newer Linux distros, systemd forces all mount namespaces to be shared, starting at /. This disables the CLONE_NEWNS flag in unshare(2) and clone(2). While this problem is most commonly seen on systems with systemd, it can happen anywhere, due to how Linux namespaces now work. Hence, to create a private mount namespace, it is not sufficient to just set CLONE_NEWS; you have to call mount(2) to change the behavior of namespaces, i.e. mount("none", "/", NULL, MS_REC|MS_PRIVATE, NULL) This is tested and working and we can now correctly start child process with private namespaces on Linux distros that use systemd. The new test works correctly on Ubuntu 16.04.2 LTS. It fails if I comment out the new Mount, and succeeds otherwise. In each case it correctly cleans up after itself.

We want to merge a load and op into a single instruction l = LOAD ptr mem y = OP x l into y = OPload x ptr mem However, all of our OPload instructions require that y uses the same register as x. If x is needed past this instruction, then we must copy x somewhere else, losing the whole benefit of merging the instructions in the first place. Disable this optimization if x is live past the OP. Also disable this optimization if the OP is in a deeper loop than the load.

This greatly improves the latency of starting a child process when the Go process is using a lot of memory. Even though the kernel uses copy-on-write, preparation for that can take up to several 100ms under certain conditions. All other goroutines are suspended while starting a subprocess so this latency directly affects total throughput. With CLONE_VM the child process shares the same memory with the parent process. On its own this would lead to conflicting use of the same memory, so CLONE_VFORK is used to suspend the parent process until the child releases the memory when switching to to the new program binary via the exec syscall. When the parent process continues to run, one has to consider the changes to memory that the child process did, namely the return address of the syscall function needs to be restored from a register. A simple benchmark has shown a difference in latency of 16ms vs. 0.5ms at 10GB memory usage. However, much higher latencies of several 100ms have been observed in real world scenarios.

The DefaultServeMux included in net/http uses a map to store routes, but iterates all keys for every request to allow longer paths. This change checks the map for an exact match first. To check performance was better, BenchmarkServeMux has been added - this adds >100 routes and checks the matches.

This change adds position information for { and } braces in the source. There's a 1.9% increase in memory use for syntax.Nodes, which is negligible relative to overall compiler memory consumption. Parsing the std library (using syntax package only) and memory consumption before this change (fastest of 5 runs): $ go test -run StdLib -fast parsed 1516827 lines (3392 files) in 780.612335ms (1943124 lines/s) allocated 379.903Mb (486.673Mb/s) After this change (fastest of 5 runs): $ go test -run StdLib -fast parsed 1517022 lines (3394 files) in 793.487886ms (1911840 lines/s) allocated 387.086Mb (267B/line, 487.828Mb/s) While not an exact apples-to-apples comparison (the syntax package has changed and is also parsed), the overall impact is small. Also: Small improvements to nodes_test.go. Change-Id: Ib8a7f90bbe79de33d83684e33b1bf8dbc32e644a Reviewed-on: https://go-review.googlesource.com/38435Reviewed-by: -
