[go-nuts] Re: Concurrent access to map

Hello, Once you have written out your values to the map, you can read them concurrently and safely. If you need to write again to it (insert or delete), then you must ensure it is done safely. Note that, from what I can see in tip, in 1.9 there will be a safe concurrent map:

Re: [go-nuts] Re: Why does gofmt by default use an 8 space indent?

The indent character is tab, whose width is your decision. That's in large part why the indent character is tab: to let you choose how much to indent. -rob On Mon, May 15, 2017 at 8:05 PM, wrote: > Because it warns you that you're probably nesting too deep and should

[go-nuts] Concurrent access to map

Hi, I am aware of golang map is not safe for concurrent access, especially when there is at least one writer. However, I want to know that if the map has been pre-populated, and different coroutines access (read/write) different key/value pair, is it safe to do so? There is no deletion or

[go-nuts] Re: Why does gofmt by default use an 8 space indent?

Because it warns you that you're probably nesting too deep and should consider breaking them into smaller functions. It's more of a coding practice, not some language standards. Read #1 from https://www.kernel.org/doc/html/v4.10/process/coding-style.html. On Friday, March 7, 2014 at 10:01:19

[go-nuts] Re: Is it ok to separate Open and Close logic?

Is there any reason that Cleanup(f) should be called within DoingStuff()? (A reason that maybe is not visible in your example but might become obvious in a more complex scenario?) Otherwise you could just call `defer Cleanup(file)` in DoStuff() with exactly the same result, and you are back

[go-nuts] [go/loader] write a conf to load faster a program ?

Hi, I wrote this func to load a program, its faster but it has drawbacks about error managements. It might hide some messages. the first time i ran this function, without a special typechecker error handler, I felt overwhelmed by the amount of errors generated. in this func s is an import path,

[go-nuts] Re: Is it ok to separate Open and Close logic?

In this kind of scenario, I recommend a (type) wrapper for *File Rework the code as: type Doer *File func NewDoer(f string) (Doer, err) { file, err := os.Open(f) // ... } func (d Doer) Close() error { return d.Close() } Everything else being the same, your caller can then expect

Don't wait. Write it yourself. Seriously, if my solution does most of what you want, but it's not quite right, it's very easy to change it. Just hack the templates. Regards Simon On Mon, May 15, 2017 at 4:41 PM, Tong Sun wrote: > Quite agree with the following. > >

Hi, Yes, this is correct, it generates epub files in versions 20/30. But it is an initial version, you really can gernerate the epubs and open in iBooks and Adobe. But it is has a long way to evolve yet. The example can be found at

Hi I am back with update. There is most certainly was memory leak connected with openCv. I don't know where is the problem yet. I can confirm this, because I have run test while mocking openCv out, there were no leaks of the type that was desbribed before. RSS was constant. Except there was
