QUESTION
Following up with How do I check the size of a Go project?
The conclusion was:
in order to get a true sense of how much extra weight importing certain packages, one has to look at all of the pkg's sub-dependencies as well.
That's totally understandable. My question is,
Is there anyway that I can know how much space each component is taking in my compiled binary, the Go runtime, the dependencies and sub-dependencies packages, and my own code.
I vaguely remember reading something like this before (when go enhanced its linker maybe).
If there has never been such discussion before, then is there any way the go or even c linker can look into the my compiled binary, and reveal something that I can further parse myself?
ANSWER
Answered 2022-Jan-19 at 21:17The binary will contain debug symbols which we can use to figure out how many space each package takes up.
I wrote a basic program to do this since I don't know of any tool that does this:
QUESTION
Looking for a way to store a turtle length of stay in the model after they have left the model. My model runs for several months and a few thousand turtles enter, undergo process then leave the area. It's complicate model (it's a hybrid DES and ABM) so I've tried to reproduce the simple bit below.
Turtles will be created at every tick and given a random length of stay but will only be able to begin process when they move to the right area (area-name) and when their time is up they leave the area. Their time-in-system reflects the wait for the area and the length-of-stay which I want to save once they're complete. If I leave them in the model it starts to break down after a couple of months and I suspect this is because the model has too many turtles still in the system for calculation and is inefficient.
...ANSWER
Answered 2021-Oct-20 at 10:11You should create a list storing the values of turtles that left.
Isolating only the code that is relevant for this purpose, it would be something like:

QUESTION
In below Go function I am getting error when I tried to run build command to generate pb.go file. panic: interface conversion: interface {} is []uint8, not *validator.FieldValidator github.com/mygithub/myproject/plugin.getFieldValidatorIfAny(0xc0001d4b60, 0x5b5020)
Any suggestion on how to resolve this
...ANSWER
Answered 2021-Aug-27 at 16:13Per https://beta.pkg.go.dev/github.com/golang/protobuf/proto#GetExtension (emphasis mine):
If the descriptor is type complete (i.e., ExtensionDesc.ExtensionType is non-nil), then GetExtension parses the encoded field and returns a Go value of the specified type. If the field is not present, then the default value is returned (if one is specified), otherwise ErrMissingExtension is reported.
If the descriptor is type incomplete (i.e., ExtensionDesc.ExtensionType is nil), then GetExtension returns the raw encoded bytes for the extension field.
So, here it appears that validator.E_Field
is “type incomplete”. You may need to add a dependency on the package that defines the extension so that its type will be registered — perhaps by using import _ "example.com/some/proto"
to link it in to your binary.
QUESTION
This is a kind of want-to-know itch. Many questions here ask how to replace the default Django homepage (e.g. ). I understand that issue. What I'm curious to know is how the default page is rendered when a new project is created (i.e., in debug mode). Even though my question is not as directly practical as knowing how to replace the default homepage, I have the feeling that if I figure it out, I may understand how Django works a bit better.
I would expect it to be in the default urls.py file, but the only entry by default in urlpatterns
of urls.py is path('admin/', admin.site.urls)
. My first naive expectation would be an entry in urlpatterns that you could remove or comment out. Since there's nothing there besides admin/
, I'm guessing there's some other built-in app or middleware that specifies the default homepage, but I don't know where to look.
Here's my progress in understanding this so far:
- Commenting out
DEBUG=True
in settings.py causes the default homepage to no longer appear. - I've seen this documentation about how Django processes requests, which mentions middleware that can set the urlconf attribute on a request that changes the default,
ROOT_URLCONF
.
So far Django has been pretty straightforward, but this seems like something magical, so I'm trying to figure out what's going on behind the scenes.
I appreciate the help!
...ANSWER
Answered 2021-Aug-27 at 04:22The relevant code is here. Django basically has a special case for when no matching URL is found in the URL configuration, and the requested path is /
, and there is only one entry in the URL configuration.
In that case it loads a default_urlconf
which renders that welcome template in place of a regular 404 response.
This is called from inside the technical_404_response
function, which is only called when DEBUG=True
.

QUESTION
I'm not a golang developer but currently I have to fix code on it, so sorry in advance if I accidentally not understand some basic Go's concept ;) I have a third party protobuf
contract which I have to use and on which I don't have influence. I'm not able to provide actual example of the contract, so I've made similar example project on Github which has the same problem.
In short: there is a deeply nested structure of proto
documents where some of them import others:
ANSWER
Answered 2021-Aug-14 at 20:18This is more some pointers rather than a definitive answer. If I find some time tomorrow, I'll repro this to give you a definitive answer.
It is challenging. Protobufs has to find a solution for each language's package management and Go's (while IMO improved) is somewhat compounded with recent addition of Modules.
My approach my with code is to have a separate repo for the protos and generated code. If the protos change, the code is regenerated. I can either reference the generated module (!) or regenerate myself. This model keeps the protos as the definitive "source" with the timesaver of "cached" generated sources. But I'm my own 3rd-party library maintainer in this config.
So:
- Modules are manifest locally as a directory tree whose root contains
go.mod
andgo.sum
and subsidirectories representing packages. - When you generate the code for the 3rd-party protos, I think it would be best to create this under their own module, either as a standalone directory or as a vendored subdirectory.
- This module should be named to reference the 3rd party and can be created with
go mod init
and should contain the output ofprotoc
- Modules are usually pulled from a proxy or repo but you can circumvent this (since the 3rd party isn't hosting the generated code for you) by manually adding a
replace
to thego mod
redirecting from the module path to a local path. - From your error, this should solve the missing module issue and with a subdirectory e.g.
company
containing that generated code, should resolve the package too.
