acme: increase timer resolution to 10ms We ran for a long time with 10ms kernel resolution, so 10ms user space resolution here should be fine. Some systems actually provide 1ms sleeps, which makes this polling use a bit more cpu than we'd like. Since the timers are for user-visible things, 10ms should still be far from noticeable. Reduces acme's cpu usage on Macs when plumber is missing (and plumbproc is sleeping waiting for it to appear). LGTM=aram, r R=r, aram https://codereview.appspot.com/99570043

undo CL 69070045 / 8539a916d98a This breaks ^C in win windows, as expected. People use ^C, win expects and handles ^C, so I don't think we can just take it away. I've noticed that it is broken but assumed my ssh was screwed up. If you want to make WindowsKey+C,X,V do the operations, by analogy with command+C,X,V on Mac, that's fine with me. ««« original CL description acme: copy/cut/paste with ctl+c,x,v LGTM=rsc R=rsc CC=plan9port.codebot https://codereview.appspot.com/69070045 »»» TBR=rsc CC=burns.ethan, r https://codereview.appspot.com/96410045

acme: add log file in acme root directory Reading /mnt/acme/log reports a log of window create, put, and delete events, as they happen. It blocks until the next event is available. Example log output: 8 new /Users/rsc/foo.go 8 put /Users/rsc/foo.go 8 del /Users/rsc/foo.go This lets acme-aware programs react to file writes, for example compiling code, running a test, or updating an import block.

acme: use buffered i/o to write file Bakul Shah has observed corrupted files being written when acme writes over osxfuse to sshfs to a remote file system. In one example we examined, acme is writing an 0xf03-byte file in two system calls, first an 0x806-byte write and then a 0x6fd-byte write. (0x806 is BUFSIZE/sizeof(Rune); this file has no multibyte UTF-8.) What actually ends up happening is that an 0x806-byte file is written: 0x000-0x6fd contains what should be 0x806-0xf03 0x6fd-0x7fa contains zeros 0x7fa-0x806 contains what should be 0x7fa-0x806 (correct!) The theory is that fuse or sshfs or perhaps the remote file server is mishandling the unaligned writes. acme does not seem to be at fault. Using bio here will make the writes align to 8K boundaries, avoiding the bugs in whatever underlying piece is broken. TBR=r https://codereview.appspot.com/89550043
