[ruby/openssl] Expand tabs in C source files

2025-12-04T17:46:59+00:00

Since around 2018, we have been using spaces for indentation for newly
added code[1]. The mixed use of tabs and spaces has repeatedly confused
new contributors who configured their editors to use a different tab
size than 8. Since git blame can now skip specific commits, ruby/ruby
did a mass reformatting of tabs in 2022[2]. Do the same in ruby/openssl.

While at it, fix a few indentation issues, mainly in switch-case labels
and in ossl_ssl_session.c, which used doubled indentation size.

This patch contains white-space changes only. git diff -w output should
be empty.

[ruby/openssl] Remove dummy declarations for mOSSL and eOSSLError

2025-11-29T17:05:19+00:00

These declarations were added to every source file because older
versions of RDoc did not resolve ancestor tree across files. Since
RDoc 6.9.0 supports this, this workaround is no longer needed.

[ruby/openssl] pkey: rename ossl_pkey_new() to ossl_pkey_wrap()

2025-07-27T12:17:25+00:00

Among functions named ossl_*_new(), ossl_pkey_new() is now the only one
that takes ownership of the passed OpenSSL object instead of making a
copy or incrementing its reference counter. Rename it to make this
behavior easier to understand.

[ruby/openssl] Require OpenSSL 1.1.0 or later

2025-01-20T17:12:57+00:00

Drop support for OpenSSL 1.0.2. It has reached upstream EOL in 2019-12.

Most distributions that shipped with OpenSSL 1.0.2 have also reached
EOL, or provide a newer version in the package repository:

 - RHEL 7 (EOL 2024-06)
 - Ubuntu 16.04 LTS (EOL 2021-04)
 - Amazon Linux 2 (EOL 2026-06, but OpenSSL 1.1.1 can be installed via
   the openssl11{,-devel} package)

[ruby/openssl] engine: remove constants for ENGINE_METHOD_BN_MOD_EXP{,_CRT}

2025-01-20T17:12:55+00:00

These macros do not exist in OpenSSL 0.9.7 or later, which was released
in 2002.

[ruby/openssl] engine: remove mention of LibreSSL from OpenSSL::Engine

2025-01-14T12:38:17+00:00

These paths are only reachable when it is compiled against OpenSSL.
LibreSSL 3.9 does not support ENGINE and defines OPENSSL_NO_ENGINE.

[ruby/openssl] Fix references to the license text

2024-06-08T10:59:17+00:00

Update the references to the file "LICENCE" with "COPYING".

The file LICENCE doesn't exist in ruby/ruby nor ruby/openssl. This has
been always the case since OpenSSL for Ruby 2 was merged to the ruby
tree as a standard library in 2003.

In OpenSSL for Ruby 2's CVS repository[1], the LICENCE file contained
an old version of the Ruby License, identical to the COPYING file that
was in Ruby's tree at that time (r4128[2]).

[ruby/openssl] Implement Write Barrier for all OpenSSL types

2023-06-18T16:57:09+00:00

The vast majority have no reference so it's just a matter of setting the flags.

For the couple exception, they have very little references so it's
easy.

[ruby/openssl] engine: disable OpenSSL::Engine on OpenSSL 3.0

2021-12-20T14:42:03+00:00

The entire ENGINE API is deprecated in OpenSSL 3.0 in favor of the new
"Provider" concept.

OpenSSL::Engine will not be defined when compiled with OpenSSL 3.0.
We would need a way to interact with providers from Ruby programs, but
since the concept is completely different from the ENGINE API, it will
not be through the current OpenSSL::Engine interface.
