With this commit running blame on render_view_impl.cc[1] saves
about 644 ms over prior versions, reducing the time about 4.5%.
Large projects often contain strands of commits where no changes
are made to a particular subtree. Blame used to dive recursively
into these subtrees to look for the blob and check if its SHA-1
was changed. In chromium/src[1] only 20% of the commits modify
the content/renderer subtree relevant for the file.
The recursivePath is necessary to check for '/' and remember
if common subtree elimination should be attempted. When a file
lives within a subtree the extra cost to check for unmodified
subtrees saves time. However for files in the root tree the
extra work incurred by TreeWalk is not worthwhile and would
significantly increase overall running time.
Now typical running times from an otherwise idle desktop:

Avoid converting the raw mode to FileMode. This is an expensive
if-else-if sort of test to just check if the thing is a blob.
Instead test the bit mask directly, which is at least a few
instructions shorter.
The TreeWalk is already recursive and will auto-dive into any
subtrees found. isSubtree check is unnecessary, as is the loop,
as only one result will ever be returned by next().

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

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.

When working on a non-bare repository with a detached HEAD jgit's GC was

"refs/"

Previously, calling addAnnotatedTags() did not modify any state when
there were no annotated tags in the repository. This caused the code
to assume no addFoo() methods had been called, and fell back to the
default of adding refs/*. Instead, use null to indicate neither
addRefs() nor addAnnotatedTags() was called.
Add a test for this behavior.

Under certain circumstances isMergedInto() returned
false even though base is reachable from the tip.
This will hinder pushes and receives by falsely
detecting "non fast forward" merges.
o---o---o---o---o
/ \
/ o---o---A---o---M
/ /
---2---1-
if M (tip) was compared to 1 (base), the method
isMergedInto() could still return false, since
two mergeBases will be detected and the return
statement will only look at one of them:
return next() == base;
In most cases this would pass, but if "A" is
a commit with an old timestamp, the Generator
would walk down to "2" before completing the
walk pass "A" and first finding the other
merge base "1". In this case, the first call to
next() returns 2, which compared to base evaluates
as false.
This is fixed by iterating merge bases and
returning true if base is found among them.

Copying flags through a graph with deep side branches can cause
StackOverflowError. The recursive step to visit the 2nd parent of
a merge commit can overflow the stack if these are themselves very
deep histories with many branches.
Rewrite the loop to iterate up to 500 recursive steps deep before
unwinding the stack and running the remaining parts of the graph
using a dynamically allocated FIFORevQueue.
This approach still allows simple graphs that mostly merge short
lived topic branches into master to copy flags with no dynamic
memory allocation, relying only on temporary stack extensions.
Larger more complex graphs only pay the allocation penalities
if copying has to extend outwards "very far" in the graph, which
is unlikely for many coloring based algorithms.

Blaming with core.autocrlf set to 'true' - even for freshly checked out

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
annotations.
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
effort. In that case the whole local file will be blamed as being
locally modified.
