[go-nuts] SFTPGo 0.9.6 Released

[Nicola Murino]

Hi all,

I'm pleased to announce SFTPGo 0.9.6.

SFTPGo is a free and open source full featured and highly configurable SFTP 
server. It works on Linux, macOS and Windows.

Here are the main new features compared to 0.9.5 version:

- Keyboard interactive authentication. You can easily setup a customizable 
multi-factor authentication.
- Support for serving S3 Compatible Object Storage and Google Cloud Storage 
over SFTP/SCP.
- Integrated database schema migration. No more need to manually execute 
SQL scripts.
- Per user authentication methods. You can, for example, deny one or more 
authentication methods (password, public key, keyboard interactive) to one 
or more users.
- Virtual folders: directories outside the user home directory can be 
exposed as virtual folders.
- Dynamic user modification just before the login via external programs.
- Per user and per directory file extensions filters: files can be allowed 
or denied based on their extensions.
- Support for HAProxy PROXY protocol: you can proxy and/or load balance the 
SFTP/SCP service without losing the information about the client's address.
- Several bug fixes for SSH command parsing.
- Documentation should be less confused now.

You can find the full list of features and the documentation on the project 
page:

https://github.com/drakkan/sftpgo

Binary releases for Linux, macOS and Windows are available:

https://github.com/drakkan/sftpgo/releases

If you want to suggest a new feature or you find a bug please open an issue 
here:

Yours sincerely,
Nicola

Maybe I'm missing something, but isn't that the expected behavior for
any function that has a result of type error?  I don't see why we
would need a naming convention for that.

[go-nuts] Naming convention for "will return error if cannot be done"

[Alexander Mills]

I put the question on Quora:
https://www.quora.com/unanswered/In-Golang-mustdo-means-it-will-panic-if-it-cannot-be-done-Is-here-a-naming-convention-for-will-always-return-error-if-it-cannot-be-done

In Golang "mustdo" means it will panic() if it cannot be done. Is here a 
naming convention for "will always return error" if it cannot be done?

[go-nuts] Re: Changing source code in order code to be supported from older Golang versions e.g. Go 1.10

[Brian Candler]

I think the problem with compiling code written for go 1.14 with the 
compiler for go 1.10 is not so much the minor language features like number 
literals, but additions to the standard library which those applications 
may depend on.

This means you may need to backport parts of the standard library to go 
1.10 as well.

[Manlio Perillo]

Python has a similar policy about Windows support:
https://docs.python.org/dev/using/windows.html#supported-versions

The same for Rust:

[Jesper Louis Andersen]

While it isn't supported, it might be there are not that much work needed
to make 1.14 run on Windows XP. At least you should consider that path as
well in addition to program rewriting. It may be a simpler path.

To add:

Look up the concept of a circuit breaker and run it in reverse. Rate limit
your requests, and if the site takes too long to respond, or if it returns
a 429 or the like, you should trip the circuit breaker for a while to cool
down. Scraping can put a tremendous load on a web site and it is your duty
as the scraper to be careful. It is especially important in a language like
go, where you can easily make ten thousand requests to a website from a
single program.

Re: [go-nuts] Connection Refused while scraping the data

[Amnon Baron Cohen]

You might get better results if you at a www to the beginning of the 
hostname.

curl https://www.indeed.co.in/browsejobs/Engineering

does download a page

whereas curl https://indeed.co.in/browsejobs/Engineering
does give a connection refused error.
