Replace the links in NOTICE to the closed down Google Code
(code.google.com) with their Github counterparts where the projects
moved to.

Gitblit used to download dependencies upon first start. This has since
long been changed and everything is bundled with Gitblit now. So reflect
this in the design.mkd document, which still said they would be
downloaded.

Fix Moxie URL in build.xml (#1441)

Adjust other references to the old 'gitblit' organisation on Github to
point to the new 'gitblit-org' organisation.

Add support for Jenkins Git plugin access token,  fixes #1423

The update of JGit broke pushes to tickets. The ReceiveCommand now
requires all three arguments, oldId, newId and name, to be not null.
The ticket code handling pushes to tickets left name and old id as
null in certain cases. This is fixed by always providing values.

The merge step for using `pt` added the wrong text to the copy button.

Donated by @piradix

This fixes incorrect encodings in the _de language file which makes
the pages crash.

Adding style element `max-width:inherit` as suggested by @piradix, which
makes the access restriction icon be part of the URL box again.
This fixes #1437

This replaces clippy.sfw with Javascript for issue #1241

The `clippy.swf` Flash program is no longer needed and can be deleted.
The configuration property is now incorrectly named, but we keep the
name and update the documentation. Maybe it could be completely deleted
one day, when the clipboard.js solution is known to work and be universally
supported.

The ticket page also has some copy-to-clipboard buttons, which get
updated to work with JS instead of SWF.

This is not the ideal version, since the height is too low for the tooltip
used for the drop-down menus. Probably has something to do with the
container or something. But at least something is there now, even if
not the most beautiful.

Shockwave Flash is dead. But Gitblit still uses it to copy the repository
URLs to the clip board. Which doesn't work anymore since no browser uses
Flash anymore, so this has degraded disgracefully.

Instead, we can use JavaScript to copy directly to the clipboard, now
that there are APIs for it. So replace the use of clippy.swf on the
repository page with clipboard.js[1]. This right now only has the
functionality to copy to clipboard but now visual feedback, yet.

This addresses GH issue #1241.

Adding Ed25519 keys brings the problem that with the library currently
used, the PublicKey instance of that key is not serialisable. This
results in an exception when wicket tries to cache the UsersPage.
So change the SshKeysPanel so that the PublicKey object is removed
from the `SshKey` when the panel is detached. It can be regenerated from
the raw key data.

This updates Jetty to the latest 9.x version as of writing. The 9.x is
still running on Java 8. The update needs two code changes.

`SessionManager` was replaced with `SessionHandler`. This was documented
in the Jetty documentation.

Adding the `GitblitContext` to the `WebAppContext` will result in two
instances getting created, because the code was changed that prevents
instantiation the same listener class multiple times. (The second time
is when the web.xml is read.) Instead, it must be added to the servlet
handler of the `WebAppContext`. This results in properly adhering to the
changed internal startup flow.

Updating Jetty also resolves #1409.

Jetty 9.3 changed the `setHandler` on the ServletContextHandler to no
longer automatically detect SecurityHandler, SessionHandler, etc. It
simply passes on the setHandler request to the ContextHandler class
(with a warning logged). So make sure to explicitly use the method
`setSecurityHandler` to set the ContraintSecurityHandler responsible
for the http -> https redirection.

This branch mostly records the commit from PR #1253, so we have it in
the code base. The changes are immediately undone, because the update
to JGit version 4.8.0, as proposed in PR #1252, renders the whole
patching of JGit obsolete.

The update is done now, against reservations in that PR, because we
guess that potential issues have been found and fixed by now. JGit
is updated to the last version on the major version 4 line: 4.11.9.
Also, since upstream JGit is at v6 by now, more updates will have to
happen later on anyways.

To make the protection against illegal character sets complete, an
additional fix for Bugtraq is included, that protects against exceptions
from bugtraq should it encounter an `encoding` that cannot be handled.

Update JGit, and also update other dependencies where the 4.11 JGit
version uses newer versions than we do:
commond-codec updated to 1.9
commons-compress updated to 1.15
gson updated to 2.8.2

Catch all exceptions, and not just IOExceptions, from bugtraq formatter.
If an exception is caught, ignore the bugtraq handling of the commit
message and show the plain message. Way better then not showing anything
just because something broke in bugtraq.

Reading the encoding of a commit can result in a Unsupported- or
IllegalCharsetException. This happens when for whatever reason the
commit has an encoding recorded that the system doesn't understand.
Instead of completely failing, fallback to UTF-8.

Updating JGit fixed the issue that a commit in a repo with an unknown
character set throws an exception. This would crash the RepositoryManager.
The extra handling, which patches JGit classes during runtime is completely
removed.

Unknown encodings may cause gitblit to fail to start. This modification
injects a wrapper class in the JGit internal to fake a valid return value.

Leave the artefact until after the container has been built and tested.
In case the test fails the artefact can be still downloaded to analyse
what might have caused the container build or test to fail.

Fix conflict from earlier JGit update to 4.5
Add updated Eclipse and IntelliJ files.

Fix conflict in updated slf4j version.
Add updated Eclipse and IntelliJ files.

This brings back in a change that was implemented in a pull request
from 2017, but got lost in the chaos of multiple pull requests from
intermingling branches.

This does not only provide feedback when a SSH key cannot be parsed,
but it also does so in a way that the warning goes away when a correct
key is added. Admittedly, I have no idea how to properly do this with
a Wicket FeedbackMessage, all I could find on Google was highly
complicated.

Not only does this bring back (or really in) the fix for issue #1226,
but it also fixes #984.

Since it is a pest to get rid of a Wicket FeedbackMessage in an AJAX target,
change the code to use an extra label that can provide feedback if the
key could not be parsed or was empty.

if key is empty of can not be parsed, form did provide any feedback to
user before

The Github 'checkout' action was updated from v1 to v3. But the behaviour
changed between the two which broke this workflow.
The old action would clone other repositories not into the workspace
but parallel to the workspace. The new version does every clone/checkout
relative to the workspace. That means that where previously the
gitblit-docker repository would be cloned in parallel to the workspace
which is gitblit/gitblit, it is now cloned into the gitblit/gitblit
directory path.

So remove all the references to `../gitblit-docker`. The files are in
the current directory now.

Fix crash in Gitblit Authority for deleted users

When a user had a certificate, i.e. an entry in the Gitblit Authority
database, but the user was deleted from the Gitblit database, then the
Authority application crashes upon loading. This patch prevents the
crash. The deleted user is no longer shown in the Authority. But the
database entry still is kept. This should be improved to show deleted
users and give the possibility to delete them from the Authority's
database.

This fixes #1359

Update Guice version to 5.1.0

Update Guice to 5.1.0. This version is compatible with Java 17.
The gitblit patch of the servlet extension was ported to Guice 5.1.0,
too.
The update of Guice requires an update of the Guava version, too.
Thus Guava is updated to 27.0.1-jar.

Fix null pointer exception in FileSettings

Fix a null pointer access in the `toString` method for a freshly created
`FileSettings`.

Update workflows due to deprecations in actions

The `set-output` command was deprecated. The new way to set an output
parameter for a step is to echo to the file stored in `$GITHUB_OUTPUT`

Versions are updated for various actions that have a new version which
uses NodeJS 16.

One action has no updated version available yet:
`e1himself/goss-installation-action`
But an issue exists mentioning that it needs an update.

The workflow runs started issuing warnings because NodeJS 12 was
deprecated. Actions need to get updated to newer versions that use
NodeJS 16. This commit updates the `actions/checkout` and the
`actions/setup-java` actions to the latest version in the workflow that
builds on every push.

The new setup-java action requires the distribution to be specified,
since multiple JDK distributions are supported now. We chose Eclipse's
Temurin here which is the successor to AdoptOpenJDK, which we use for
development.

Build pull requests, just like we build on every push.
