[go-nuts] buffered io.ReaderAt

hi there, I know about bufio.Reader that provides a buffered version of an io.Reader. Has anybody written a buffered version of an io.ReaderAt ? I have this binary file format that implicitly forces decoders of said format to fetch data using ReadAt. In C/C++, that's OK because files are open

Re: [go-nuts] Re: Confusion about C++ calling go

another important tip: My c++ program forked to daemonlize. The golang-part is first called in the third child process(the standard daemonlize procedure forks twice). If I don't daemonlize my program, the go-gc won't hang.So strange. 在 2017年9月16日星期六 UTC+8下午4:31:25，wolfk...@gmail.com写道： > >

Re: [go-nuts] Re: Confusion about C++ calling go

I found golang gc will hang when started from a daemonlized c++ program. But fine if not daemonlized. 在 2017年9月13日星期三 UTC+8上午1:22:35，Ian Lance Taylor写道： > > On Tue, Sep 12, 2017 at 9:52 AM, > wrote: > > > > To be precise, I want to know if the garbage-collection thread

Hi, I released jsondoc a command line tool used to simplify creation of documentation of HTTP (REST) JSON APIs for projects written in Go. The input and/or output JSON structure for particular endpoints is obtained from named types from selected Go packages. The output of jsondoc is an HTML file

Does calling the cancel func on a context that is attached to a http.Request change the contents of the body to context cancellation? On Friday, 15 September 2017 18:15:25 UTC+1, Steven Lee wrote: > > Hello, > > I was wondering if anyone could help me with understanding the behaviour > of

Re: [go-nuts] buffered io.ReaderAt

ah! I thought I had scrutinized your repos for such a thing (you usually have quite the gems over there) but overlooked that one. thanks. sadly, the improvement wasn't impressive (probably a testimony to the performances of the linux filesystem layer...) copying the whole file's content into a

I think it's fine to ask questions about 32bit implementations of Go here. For Go specific things like interfacing with hardware https://gobot.io/ or https://periph.io/ may be better choices. On Sunday, 17 September 2017 06:21:45 UTC+10, Norbert Fuhs wrote: > > Hi, > > since I'm running Go on

Re: [go-nuts] Go on ARM 32bit and 64bit resources and groups

Is there anything specific you are looking for ? I extensively use go on pi and pretty much everything is very similar, i develop on my mac book and CI cluster deploys it. On non arm arch, its just as simple as setting up GOARCH and GOARM variables... thats all I have a whole build/ci stack as

[go-nuts] Re: context cancellation flake

Hi Steven, In case it's still unclear, you need to wrap both the "do request" + "read body" inside the same cancellation context. The "defer cancel" should encompass both of them, sort of atomically, so the idea is to take it out of your fetch, one level up.
