[go-nuts] Re: godoc memory leak

[Agniva De Sarker]

Couple of questions:

1. What version of godoc and Go are you using ? What is your go env ?

2. You are using -index but not passing an index file. Any reason for that 
? godoc will load faster if you write an index beforehand and pass that.

3. I am guessing since you have set index_interval, you expect files to be 
added in your GOPATH. How many new files are getting added while godoc is 
running ?

4. Please show us the output by adding -v flag.

[go-nuts] godoc memory leak

[christopher.dang via golang-nuts]

Hi all,


I've been playing around with an internal godoc server and noticed that 
over long periods of time the memory growth is unbounded. The command I use 
to invoke godoc is *godoc -index=true -index_interval=15m 
-index_throttle=.30 -maxresults=0*. The following images below track the 
memory usage and change in memory usage over a 24 hour period on a 8 GiB 
machine. I've also attached a pdf with the data points I gathered during 
the experiment. Notice how the godoc process consumes 76% of memory by the 
end of the experiment. Is this indicative of a memory leak in the godoc 
source code or is this expected behavior?

Re: [go-nuts] Go GTK vs QT for Linux

[Tyler Compton]

I haven't personally used this library, but I'd think you'd only
need libgtk-3-dev and libappindicator3-dev at compile-time. You should be
able to get away with the smaller runtime packages libgtk-3-dev
and libappindicator3-1 once your application is built.

Re: [go-nuts] Bugs on switch

[Tyler Compton]

Andrew is right, but I'll also add that if you really do want fallthrough
semantics, you can use the "fallthrough" keyword:
https://play.golang.com/p/x2gBb905Hj0

Go opts to make the somewhat uncommon case of fallthrough explicit, and the
more common "break" case implicit. A bit surprising for new Go programmers
but it does allow for most switch statements to be quite a bit less verbose.

A couple of comments. Without  actually doing the work myself, I would say 
there should be a number of ways to do this using simple date math. This 
should be made easier since you are only concerned with days and not times. 
Creating and walking slices may work, but it seems clumsy and certainly 
inefficient. Also, you code mixes together the code that creates the sample 
data with the actual work all in main().  Refactoring the code to contain a 
function that takes the 4 dates and returns the overlap, and then using 
that function in main, with the sample data, would make it easier to read, 
understand, and refactor.

Not looking for a flame war, but I see this kind of post with some 
regularity in this group, usually with no complaints. I see how it could 
get out of hand, but at the current levels, I find these posts helpful, or 
at worst innocuous. So that's another perspective. Thanks Ali for the post.

Re: [go-nuts] Bugs on switch

[Andrew Klager]

I'm going to guess, based on the "break" statement in the final case, that
you expect each of the case statements without a break to fall through to
the nest case. Go does not work like that. By default, each case, whether
there's any action taken or not, breaks. Take a look at this to accomplish
what you're probably looking for: https://play.golang.org/p/0aXXjoshOk9

[go-nuts] Go GTK vs QT for Linux

[Subramanian Sridharan]

Hi guys

I've been fiddling around this  package 
which uses GTK bindings in Go to achieve systray functionality.
But it depends on *libgtk-3-dev *and* libappindicator3-dev *which amount to 
around 300 MB.

Have you guys come across any other package that implements GTK or QT 
binding in Go?

How do GTK and QT weight against each other with respect to Go?
