Konrad Kügler c2fb432cde blame: Fix merges, where merge result differs only by whitespace
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.

Jean-Jacques Lafay 8b65a4e6c6 Fix push to repo with non-fetched refs
When JGit uses bitmaps (which is the case after a gc), the push command
doesn't go through the code where MissingObjectExceptions are caught
for remote objects not found locally.

Fixed by removing earlier non-locally-found remote objects.

This was seen withing gerrit, see:

Robin Rosenberg 36f58ef867 Fix ArrayIndexOutOfBoundsException in CreateBranchCommand
If remote name contains / or there was a branch directly under the
refs/remotes namespace (wrong) the computation of remote name and
suggested local branch name would fail. Fix this by looking at the
configured remotes. A ref under refs/remotes that does not match a
remote configuration is not considered a remote tracking branch anymore.

This patch does not fix all similar errors in EGit/JGit.

never be found.

On failures, try reloading the knonwn_hosts and retry the
connection, in addition to reloading the credentials.

When a commit is blamed for multiple lines of the result file the
command line interface prints the same text before each line in that
span.  Format these strings once and reuse them as the line prefix.

For long files (e.g. 2425 lines of ReceiveCommits.java in Gerrit)
this can save as much as 20ms during the output phase of the command
line blame program.

Shawn Pearce 6de12836d7 blame: Reduce running time ~4.5% by skipping common subtrees
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:

  real	0m13.387s  0m13.341s  0m13.443s
  user	0m15.410s  0m15.220s  0m15.350s

previously:

  real	0m14.085s  0m14.049s  0m13.968s
  user	0m15.730s  0m15.820s  0m15.770s

Shawn Pearce 52500d3264 blame: Micro optimize blob lookup in tree
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().

Konrad Kügler 551f3a0fa5 Blame correctly in the presence of conflicting merges
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.
