Connecting to an SshSession may fail due to different reasons. Jsch for
example often throws an com.jcraft.jsch.JschException: verify: false.[1]
The issue is still not fixed in JSch 0.1.51.
In such a case it is worth retrying to connect. The number of connection
attempts can be configured using ssh_config parameter
"ConnectionAttempts" [2].
Don't retry if the user canceled authentication.

The current behavior of passing a TreeFilter to RevWalk has limited
usefulness, since the RevFilter derived from the TreeFilter is always
ANDed together with any other RevFilters. It is also tied fairly
tightly to the parent rewriting mechanism.
Make TreeRevFilter a generic RevFilter that matches modified paths
against any TreeFilter. This allows for more complex logic like
(modified this path OR authored by this person).
Leave the rewrite flag logic in this class, since it's closely tied to
the parent comparison code, but hidden behind a protected constructor.

If a client passes a multiline message as argument to ReflogWriter.log()
the Reflog gets corrupted and cannot be parsed. ReflogWriter.log() is
invoked implicitly from various commands such as StashCreate, Rebase and
many more. However the message is not always filtered for line feeds.
Such an example is the StashCreateOperation of EGit which passes
unchecked user input as commit message. If a multiline comment is pasted
to the stash create dialog, the reflog gets corrupted.
ReflogWriter now replaces line endings in log message with spaces.

The aim of this change is to place all commits of a branch on the same
lane and commits of other (side) branches on different lanes.
The algorithm treats first parents of a commit specially by placing them
on the same lane as the commit itself. When a commit is the first parent
of multiple children it could be placed on any of these children's
lanes. In this case it is placed on the longest child lane, as this is
usually the lane of the branch the commit actually was made on.
Other (non-first) parents are placed on new lanes. This creates a layout
that should make it easier to see branches and merges and follow linear
branch histories.
This differs from the previous approach, which sometimes plotted the
commits of a side branch on the same lane as the base branch commits and
further commits on the base branch appeared on a different lane.
This made the base branch appear as if it was the side branch and
the side branch appears to be the base branch.
In addition to lane assignment, also the plotting code changed to start
drawing a branch lane from the commit where it forks out. Previously it
started only when the first commit on the branch appeared.
Active lanes are continued with every commit that is processed.
Previously lanes were only continued when the next commit on the lane
was encountered. This could produce (temporarily) dangling commits if
the next commit on the lane was not processed yet.

Previously, setting any TreeFilter on a RevWalk triggered parent
rewriting, which in the current StartGenerator implementation ends up
buffering the entire commit history in memory. Aside from causing poor
performance on large histories, this does not match the default
behavior of `git rev-list`, which does not rewrite parent SHAs unless
asked to via --parents/--children.
Add a new method setRewriteParents() to RevWalk to disable this
behavior. Continue rewriting parents by default to maintain backwards
compatibility.

When blaming a merge commit with "Ignore whitespace changes" enabled,
don't discard blame candidates for other parents when we encounter a
parent that only has whitespace changes compared to the merge result.
The algorithm early prepares parents for blaming, removing the
appropriate blame regions from the list of regions still to blame. Only
at the end, the prepared blame candidates are submitted for blaming.
When looking at a non-first parent which only differs in whitespace to
the merge result, it submitted that parent, but only to blame it for the
(usually few) lines not already prepared to blame on other parents. Due
to an early return the blame candidates for the previous parents were
forgotten, leaving many lines unannotated.

Problem:
The BlameGenerator used the RevFlag SEEN to mark commits it had
already looked at (but not necessarily processed), to prevent
processing a commit multiple times. If a commit is a conflicting
merge that contains lines of the merge base, that have been deleted
in its first parent, either these lines or the lines untouched
since the merge base would not be blamed properly.
This happens for example if a file is modified on a main branch in an
earlier commit M and on a side branch in a later commit S. For this
example, M deletes some lines relative to the common base commit B,
and S modifies a subset of these lines, leaving some other of these
lines untouched.
Then side is merged into main, creating a conflict for these
lines. The merge resolution shall carry over some unmodified lines
from B that would otherwise be deleted by M. The route to blame
these lines is via S to B. They can't be blamed via M, as they
don't exist there anymore.
Q
|\
| \
| S
| |
M |
| /
|/
B
Blaming the merged file first blames via S, because that is the
most recent commit. Doing so, it also looks at B to blame the
unmodified lines of B carried over by S into the merge result. In the
course of this, B is submitted for later processing and marked SEEN.
Later M is blamed. It notices that its parent commit B has been
SEEN and aborts processing for M. B is blamed after that, but only
for the lines that survived via S.
As a result, only the lines contributed by S or by B via S are
blamed. All the other lines that were unchanges by both M and S,
which should have been blamed to B via M, are not blamed.
Solution:
Don't abort processing when encountering a SEEN commit. Rather add the
new region list of lines to be blamed to those of the already SEEN and
enqueued commit's region list. This way when the B commit of the
above example is processed, it will blame both the lines of M and S,
yielding a complete blame result.

the line breaks of the local file will be converted to LF for blaming.
This results in useful diffs and therefor in the desired blame

For autocrlf = input no conversion takes place to cope with CRLF line
breaks in the repository, in addition to the usual LF. For autocrlf =
true CRLF line breaks in the repo can't be supported without additional

Previously all HTTP communication was done with the help of
java.net.HttpUrlConnection. In order to make JGit usable in environments
where the direct usage of such connections is not allowed but where the
environment provides other means to get network connections an
abstraction for connections is introduced. The idea is that new
implementations of this interface will be introduced which will not use
java.net.HttpUrlConnection but use e.g.
org.apache.client.http.HttpClient to provide network connections.
One example: certain cloud infrastructures don't allow that components
in the cloud communicate directly with HttpUrlConnection. Instead they
provide services where a component can ask for a connection (given a
symbolic name for the destination) and where the infrastructure returns
a preconfigured org.apache.http.client.HttpClient. In order to allow
JGit to be running in such environments we need the abstraction
introduced in this commit.
