Thomas Wolf 4d7a16257f Include full IssuerFingerprint in GPG signature
Update dependency to Bouncy Castle to 1.65.

Add the IssuerFingerprint as a hashed sub-packet in the signature. If
added unhashed, GPG ignores it.

Yunjie Li 913234e2ec PackBitmapIndex: Set distance threshold
Setting the distance threshold to 2000 in PackWriterBitmapPreparer to
reduce memory usage in garbage collection. When the threshold is 0, GC
for the msm repository would use about 37 GB memory to complete. After
setting it to 2000, GC can finish in 75 min with about 10 GB memory.

Yunjie Li 3aee92478c PackBitmapIndex: Not buffer inflated bitmap in BasePackBitmapIndex
Currently we're buffering the inflated bitmap entry in BasePackBitmapIndex
to optimize running time. However, this will use lots of memory during
the construction of the pack bitmap index file which may cause failure of
garbage collection.

The running time didn't increase significantly, if there's any increase,
after removing the buffering here. The report about usage of time/memory
will come in the next commit.

Yunjie Li e250482c7a PackBitmapIndex: Remove convertedBitmaps in the Remapper
The convertedBitmaps serves for time-optimization purpose. But it's
actually not saving time much but using lots of memory. So remove the
field here to save memory.

Currently the remapper class is only used in the construction of the
bitmap index file. And during the preparation of the file, we're only
getting bitmaps from the remapper when finding objects accessible from
a commit, so bitmap associated with each commit will only be fetched once
and thus the convertedBitmaps would hardly be read, which means that it's
not saving time.

Yunjie Li dcb0265436 PackBitmapIndex: Reduce memory usage in GC
Currently, the garbage collection is consistently failing for some large
repositories in the building bitmap phase, e.g.Linux-MSM project:
https://source.codeaurora.org/quic/la/kernel/msm-3.18

Historically, bitmap index creation happened in 3 phases:
1. Select the commits to which bitmaps should be attached.
2. Create all bitmaps for these commits, stored in uncompressed format
in the PackBitmapIndexBuilder.
3. Deltify the bitmaps and write them to disk.

We investigated the process. For phase 2 it's most efficient to create
bitmaps starting with oldest commit and moving to the newest commit,
because the newer commits are able to reuse the work for the old ones.
But for bitmap deltification in phase 3, it's better when a newer
commit's bitmap is the base, and the current disk format writes bitmaps
out for the newest commits first.

This change introduces a new collection to hold the deltified and
compressed representations of the bitmaps, keeping a smaller subset of
commits in the PackBitmapIndexBuilder to help make the bitmap index
creation more memory efficient.

And in this commit, we're setting DISTANCE_THRESHOLD to 0 in the
PackWriterBitmapPreparer, which means the garbage collection will not
have much behavoir change and will still use as much memory as before.

Yunjie Li 067d946090 PackBitmapIndex: Add AddToBitmapWithCacheFilter class
Add a new revwalk filter, AddToBitmapWithCachedFilter. This filter updates
a client-provided {@code BitmapBuilder} as a side effect of a revwalk.
Similar to {@code AddToBitmapFilter}, it short circuits the walk when it
encounters a commit which is included in the provided bitmap's BitmapIndex.
It also short circuits the walk if it encounters the client-provided
cached commit.

  ReceivePack: adding IterativeConnectivityChecker
  Moving transport/internal -> internal/transport
2020-05-11 17:40:20 -04:00
Demetr Starshov 9075beefb1 ReceivePack: adding IterativeConnectivityChecker
Introduce an IterativeConnectivityChecker which runs a connectivity
check with a filtered set of references, and falls back to using the
full set of advertised references.

It uses references during first check attempt:
- References that are ancestors of an incoming commits (e.g., pushing
a commit onto an existing branch or pushing a new branch based on
another branch)
- Additional list of references we know client can be interested in
(e.g. list of open changes for Gerrit)

We tested it inside Google and it improves connectivity for certain
topologies. For example connectivity counts for
chromium.googlesource.com/chromium/src:

percentile_50: 1923 (was: 22777)
percentile_90: 23272 (was: 353003)
percentile_99: 345522 (was: 353435)

This saved ~2 seconds on every push to this repository.

Jack Wickham d69c0ef5bd Create parent directories when renaming a file in ApplyCommand
Before this change, applying a patch will fail if the destination directory
doesn't exist; after, the necessary parent directories are created.

If renaming the file fails, the directories won't be deleted, so this change
isn't atomic. However, ApplyCommand is already not atomic - if one hunk fails
to apply, other hunks still get applied - so I don't think that is a blocker.

Thomas Wolf 2640d38f14 FS.runInShell(): handle quoted filters and hooksPath containing blanks
Revert commit 2323d7a. Using $0 in the shell command call results in
the command string being taken literally. That was introduced to fix
a problem with backslashes, but is actually not correct.

First, the problem with backslashes occurred only on Win32/Cygwin,
and has been properly fixed in commit 6f268f8.

Second, this is used only for hooks (which don't have backslashes in
their names) and filter commands from the git config, where the user
is responsible for properly quoting or escaping such that the commands
work.

Third, using $0 actually breaks correctly quoted filter commands
like in the bug report. The shell really takes the command literally,
and then doesn't find the command because of quotes.

So revert this change.

At the same time there's a related problem with hooks. If the path to
the hook contains blanks, runInShell() would also fail to find the
hook. In this case, the command doesn't come from user input but is
just a Java File object with an absolute path containing blanks. (Can
occur if core.hooksPath points to such a path with blanks, or if the
repository has such a path.)

The path to the hook as obtained from the file system must be quoted.

Add a test for a hook path with a blank.

This reverts commit 2323d7a1ef.

Ivan Frade 7d3b6308fc ResolveMerger: Ignore merge conflicts if asked so
The recursive merge strategy builds a virtual ancestor merging
recursively the common bases (when more than one) between the
want-to-merge commits. While building this virtual ancestor, content
conflicts are ignored, but current code doesn't do so when a file is
removed.

This was spotted in [1], for example. Merging two commits to build the
virtual ancestor bumped into a conflict (modified in one side, deleted
in the other) that stopped the process.

Follow the "spec" and in case of conflict leave the unmerged content in
the index and working trees.

The error message for an Exception thrown by StartGenerator when given
both the TOPO flag and the TOPO_KEEP_BRANCH_TOGETHER flag mentions a
non-existent flag, TOPO_NON_INTERMIX. The error message was introduced
in commit e498d43.

Replace TOPO_NON_INTERMIX with TOPO_KEEP_BRANCH_TOGETHER in the error
message of an Exception thrown by the StartGenerator when the TOPO flag
is provided together with the TOPO_KEEP_BRANCH_TOGETHER flag.

Alex Spradlin e498d43186 RevWalk: new topo sort to not mix lines of history
The topological sort algorithm in TopoSortGenerator for RevWalk may mix
multiple lines of history, producing results that differ from C git's
git-log whose man page states: "Show no parents before all of its
children are shown, and avoid showing commits on multiple lines of
history intermixed." Lines of history are mixed because
TopoSortGenerator merely delays producing a commit until all of its
children have been produced; it does not immediately produce a commit
after its last child has been produced.

Therefore, add a new RevSort option called TOPO_KEEP_BRANCH_TOGETHER
with a new topo sort algorithm in TopoNonIntermixGenerator. In the
Generator, when the last child of a commit has been produced, unpop
that commit so that it will be returned upon the subsequent call to
next(). To avoid producing duplicates, mark commits that have not yet
been produced as TOPO_QUEUED so that when a commit is popped, it is
produced if and only if TOPO_QUEUED is set.

To support nesting with other generators that may produce the same
commit multiple times like DepthGenerator (for example, StartGenerator
does this), do not increment parent inDegree for the same child commit
more than once.

Commit b5e764abd2 modified the existing
TopoSortGenerator to avoid mixing lines of history, but it was reverted
in e40c38ab08 because the new behavior
caused problems for EGit users. This motivated adding a new Generator
for the new behavior.
