Please prepare tiny_tds gem for Ruby v3.0 on Windows

[ecentell-CPF]

Windows 10 Pro 2004

ERROR: Error installing tiny_tds:

tiny_tds-2.1.5-x64-mingw32 requires ruby version < 2.8.dev, >= 2.4, which is
incompatible with the current version, ruby 3.0.2p107

This is using the pre-compiled Windows gem on Rubygems.org

Please advise. Thanks!

@aharpervc Since you were so helpful last time, any chance you can assist in getting the right resources to comment on this? Thanks!

[ecentell-CPF]

Copying in anyone in the @ preview list (I apologize if you are copied and have no authority in this gem)...we rely on this gem and this is stopping our Ruby 3.0 upgrade. Is there any plans to upgrade compatibility? @metaskills @jeremyevans @ebryn @luislavena

[ecentell-CPF]

Devs that committed to this project...could anyone make any comments on this ticket or the proposed PR? @bvogelzang @aharpervc @wpolicarpo @larskanis

[ecentell-CPF]

Monthly Check in @metaskills @coderjoe @bvogelzang @aharpervc thanks!

[aharpervc]

It looks like @lambacck has started work on this over in #509. You could help this process along by investigating why that change has caused the CI job to fail, and the contributing your own commits/PR to fix it.

Since i have no working knowledge of AppVeyor I cannot contribute much to it. But looking at the log

error: '/var/cache/pacman/pkg/zstd-1.4.7-1-x86_64.pkg.tar.xz': invalid or corrupted package (PGP signature)
loading packages...
Command exited with code 1

It looks like the environment itself has issues. https://help.appveyor.com/discussions/problems/27815-build-failing-due-to-key-error and https://www.msys2.org/news/#2020-06-29-new-packagers

I figured it out thanks to stackoverflow posts, by looking at the freetds windows zipfile and the installed pacman package.

It's probably looking for the include folder headers at C:\Ruby31-x64\msys64\ucrt64\include
However it is at C:\Ruby31-x64\msys64\ucrt64\include\freetds
The .exe files interestingly are at C:\Ruby31-x64\msys64\ucrt64\bin and are found.

 gem install tiny_tds -- --with-freetds-include=C:\Ruby31-x64\msys64\ucrt64\include\freetds

I don't know how to fix that in the gem. I however confirmed that this workaround is working with Ruby+Devkit 3.1.2-1

How to make sure bundle install works:
bundle config build.tiny_tds --with-freetds-include=C:\Ruby31-x64\msys64\ucrt64\include\freetds

Which shell/terminal are you using?
Cygwin? Try cmd or powershell. The \ character is apparently being as escape character. Try doubling it and see what happens (\ instead ) or quotes.

with-freetds-include=C:Ruby31-x64msys64ucrt64includefreetds

[jmunnik]

When looking at https://rubygems.org/ it looks like ;

tiny_tds 2.1.5-x64-mingw32 -> REQUIRED RUBY VERSION: >= 2.4, < 2.8.DEV
tiny_tds 2.1.5 -> REQUIRED RUBY VERSION: >= 2.0.0

Does this work at all on ruby 3.x ?

@Largo or @ecentell-CPF I'm currently using Chef Infra Client, version 17.9.52 which is using ruby 3.x if I'm not mistaken.
What are the exact steps you took in order to resolve this ?

Beside the usual install I've also tried the following ;

1. I've download https://sourceforge.net/projects/freetdswindows/files/FreeTDS-1.00/FreeTDS-1.00-x86.zip/download
2. Extracted it in C:\freetds-1.00
3. and executed C:\opscode\chef\embedded\bin> gem install tiny_tds -- --with-freetds-include=C:\freetds-1.00 from the command line on the Windows Server 2022 server.

See below the output when installing normally and with the actions as mentioned above.

I installed Ruby+Devkit 3.1.2-1 (x64) but use MINGW64 bash as configured within Visual Studio Code's Terminal:

gem install never had a problem finding the sybdb library, only the headers; the dependencies are located at:

$ ls /c/Ruby31-x64/msys64/ucrt64/include/freetds/syb*
/c/Ruby31-x64/msys64/ucrt64/include/freetds/sybdb.h  /c/Ruby31-x64/msys64/ucrt64/include/freetds/syberror.h  /c/Ruby31-x64/msys64/ucrt64/include/freetds/sybfront.h
$ ls /c/Ruby31-x64/msys64/ucrt64/lib/*sybdb*
/c/Ruby31-x64/msys64/ucrt64/lib/libsybdb.a  /c/Ruby31-x64/msys64/ucrt64/lib/libsybdb.dll.a

Looking at extconf.rb the FREETDS_DIR environment variable is added directly to the list of directories searched:

tiny_tds/ext/tiny_tds/extconf.rb

Lines 39 to 41 in e3e79a0

	# Grab freetds environment variable for use by people on services like
	# Heroku who they can't easily use bundler config to set directories
	DIRS.unshift(ENV['FREETDS_DIR']) if ENV.has_key?('FREETDS_DIR')

With a bit of further fiddling (./include/freetds was appended automatically), the gem was successfully installed:

$ FREETDS_DIR=/c/Ruby31-x64/msys64/ucrt64 gem install tiny_tds

The .exe files interestingly are at C:\Ruby31-x64\msys64\ucrt64\bin and are found.

Can you please explain which *.exe files you mean exactly?

I have the problem (Win 11 with Ruby 3.1.3p185), that the build of the gems works fine. Even require 'tiny_tds' returns true, but when trying to establish a connection the error Adaptive Server connection failed (localhost) (TinyTds::Error) .

With Ruby 2.7.6p219 and tiny_tds 2.1.5-x64-mingw32 everything works fine.

As per #530 this is working in 3.0
