PackInserter: Ensure objects are written at the end of the pack
ObjectInserter: Add warning about mixing read-back with writes
Change-Id: I308e7c1c6b72e8d4d9b5d0f4f51e9815fc92d7d7
When interleaving reads and writes from an unflushed pack, we forgot to
reset the file pointer back to the end of the file before writing more
new objects. This had at least two unfortunate effects:
* The pack data was potentially corrupt, since we could overwrite
previous portions of the file willy-nilly.
* The CountingOutputStream would report more bytes read than the size
of the file, which stored the wrong PackedObjectInfo, which would
cause EOFs during reading.
We already had a test in PackInserterTest which was supposed to catch
bugs like this, by interleaving reads and writes. Unfortunately, it
didn't catch the bug, since as an implementation detail we always read a
full buffer's worth of data from the file when inflating during
readback. If the size of the file was less than the offset of the object
we were reading back plus one buffer (8192 bytes), we would completely
accidentally end up back in the right place in the file.
So, add another test for this case where we read back a small object
positioned before a large object. Before the fix, this test exhibited
exactly the "Unexpected EOF" error reported at crbug.com/gerrit/7668.

Previously, Config was using the same method for both escaping and
parsing subsection names and config values. The goal was presumably code
savings, but unfortunately, these two pieces of the git config format
are simply different.
In git v2.15.1, Documentation/config.txt says the following about
subsection names:
"Subsection names are case sensitive and can contain any characters
except newline (doublequote `"` and backslash can be included by
escaping them as `\"` and `\\`, respectively). Section headers cannot
span multiple lines. Variables may belong directly to a section or to
a given subsection."
And, later in the same documentation section, about values:
"A line that defines a value can be continued to the next line by
ending it with a `\`; the backquote and the end-of-line are stripped.
Leading whitespaces after 'name =', the remainder of the line after
the first comment character '#' or ';', and trailing whitespaces of
the line are discarded unless they are enclosed in double quotes.
Internal whitespaces within the value are retained verbatim.
Inside double quotes, double quote `"` and backslash `\` characters
must be escaped: use `\"` for `"` and `\\` for `\`.
The following escape sequences (beside `\"` and `\\`) are recognized:
`\n` for newline character (NL), `\t` for horizontal tabulation (HT,
TAB) and `\b` for backspace (BS). Other char escape sequences
(including octal escape sequences) are invalid."
The main important differences are that subsection names have a limited
set of supported escape sequences, and do not support newlines at all,
either escaped or unescaped. Arguably, it would be easy to support
escaped newlines, but C git simply does not:
$ git config -f foo.config $'foo.bar\nbaz.quux' value
error: invalid key (newline): foo.bar
baz.quux
I468106ac was an attempt to fix one bug in escapeValue, around leading
whitespace, without having to rewrite the whole escaping/parsing code.
Unfortunately, because escapeValue was used for escaping subsection
names as well, this made it possible to write invalid config files, any
time Config#toText is called with a subsection name with trailing
whitespace, like {foo }.
Rather than pile hacks on top of hacks, fix it for real by largely
rewriting the escaping and parsing code.
In addition to fixing escape sequences, fix (and write tests for) a few
more issues in the old implementation:
* Now that we can properly parse it, always emit newlines as "\n" from
escapeValue, rather than the weird (but still supported) syntax with a
non-quoted trailing literal "\n\" before the newline. In addition to
producing more readable output and matching the behavior of C git,
this makes the escaping code much simpler.
* Disallow '\0' entirely within both subsection names and values, since
due to Unix command line argument conventions it is impossible to pass
such values to "git config".
* Properly preserve intra-value whitespace when parsing, rather than
collapsing it all to a single space.

When we are cloning we have no refs at all yet, and there cannot
(or at least should not) be any other thread doing something with
refs yet.
Locking loose refs is thus not needed, since there are no loose
refs yet and nothing should be trying to create them concurrently.
Let's skip the whole loose ref locking when we are cloning a repository.
As a result, JGit will write the refs directly to the packed-refs
file, and will not create the refs/remotes/ directories nor the
lock files underneath when cloning and packed refs are used. Since
no lock files are created, any problems on case-insensitive file
systems with tag or branch names that differ only in case are avoided
during cloning.
Detect if we are cloning based on the following heuristics:
* HEAD is a dangling symref
* There is no loose ref
* There is no packed-refs file
Note, however, that there may still be problems with such tag or
branch names later on. This is primarily a five-minutes-past-twelve
stop-gap measure to resolve the referenced bug, which affects the
Oxygen.2 release.

When running on NFS there was a chance that JGits LockFile
semantic is broken because File#createNewFile() may allow
multiple clients to create the same file in parallel. This
change provides a fix which is only used when the new config
option core.supportsAtomicCreateNewFile is set to false. The
default for this option is true. This option can only be set in the
global or the system config file. The repository config file is not
taken into account in this case.
If the config option core.supportsAtomicCreateNewFile is true
then File#createNewFile() is trusted and the behaviour doesn't
change.
But if core.supportsAtomicCreateNewFile is set to false then after
successful creation of the lock file a hardlink to that lock file is
created and the attribute nlink of the lock file is checked to be 2. If
multiple clients manage to create the same lock file nlink would be
greater than 2 showing the error.

the config file to java.net.Socket.setSoTimeout(). That

The missing conversion in Jsch means that the timeout is
set way too low, and if the server doesn't respond within
that very short time frame, Jsch kills the connection and
then throws an exception with a message such as "session is
down" or "timeout in waiting for rekeying process".
As a work-around, do the conversion to milliseconds in the
Jsch-facing Config interface of OpenSshConfig. That way Jsch
already gets these values as milliseconds.

Currently, unless RequestPolicy#ANY is used, UploadPack rejects all
non-commit "want" lines unless they were advertized. This is fine,
except when "uploadpack.allowreachablesha1inwant" is true
(corresponding to RequestPolicy#REACHABLE_COMMIT), in which case one
would expect that "want"-ing anything reachable would work.
(There is no restriction that "want" lines must only contain commits -
it is allowed for refs to directly point to trees and blobs, and
requesting for them using "want" lines works.)
This commit has been written to avoid performance regressions as much
as possible. In the usual (and currently working) case where the only
unadvertized things requested are commits, we do a standard RevWalk in
order to avoid incurring the cost of loading bitmaps. However, if
unadvertized non-commits are requested, bitmaps are used instead, and
if there are no bitmaps, a WantNotValidException is thrown (as is
currently done).

Make PackWriterBitmapWriter class public and move it to a more central
location, in preparation for its use by another class (in a subsequent
commit).
One of its inner static classes, AddUnseenToBitmapFilter, previously
package-private, is also used directly in its former package. Therefore,
AddUnseenToBitmapFilter and its sibling class have been moved to an
internal package instead.

JSch unconditionally overrides the user name given in the connection
URI by the one found in ~/.ssh/config (if that does specify one for
the used host). If the SSH config file has a different user name,
we'll end up using the wrong name, which typically results in an
authentication failure or in Eclipse/EGit asking for a password for
the wrong user.
Unfortunately there is no way to prevent or circumvent this Jsch
behavior up front; it occurs already in the Session constructor at
com.jcraft.jsch.Session() and the Session.applyConfig() method. And
while there is a Session.setUserName() that would enable us to correct
this, that latter method has package visibility only.
So resort to reflection to invoke that setUserName() method to ensure
that Jsch uses the user name from the URI, if there is one.

JGit's delta handling code requires the target to be a single byte
array. Any attempt to inflate a delta larger than fits in the 2GiB
limit will fail with some form of array index exceptions. Check for
this overflow early and abort pack parsing.

* stable-4.9:
PackInserter: Implement newReader()
Move some strings from DfsText to JGitText
FileRepository: Add pack-based inserter implementation
ObjectDirectory: Factor a method to close open pack handles
ObjectDirectory: Remove last modified check in insertPack
Change-Id: Ifc9ed6f5d8336bc978818a64eae122bceb933e5d
Applications that use ObjectInserters to create lots of individual
objects may prefer to avoid cluttering up the object directory with
loose objects. Add a specialized inserter implementation that produces a
single pack file no matter how many objects. This inserter is loosely
based on the existing DfsInserter implementation, but is simpler since
we don't need to buffer blocks in memory before writing to storage.
An alternative for such applications would be to write out the loose
objects and then repack just those objects later. This operation is not
currently supported with the GC class, which always repacks existing
packs when compacting loose objects. This in turn requires more
CPU-intensive reachability checks and extra I/O to copy objects from old
packs to new packs.
So, the choice was between implementing a new variant of repack, or not
writing loose objects in the first place. The latter approach is likely
less code overall, and avoids unnecessary I/O at runtime.
The current implementation does not yet support newReader() for reading
back objects.

GC explicitly handles the case where a new pack has the same name as an
existing pack due to it containing the exact same set of objects. In
this case, the pack passed to insertPack will have the same name as an
existing pack, but it will also almost certainly have a later mtime than
the existing pack.
The loop in insertPack tried to short-circuit when inserting a new pack,
to avoid walking more of the pack list than necessary. Unfortunately,
this means it will never get to the check for an identical name,
resulting in a duplicate entry for the same PackFile in the pack list.
Remove the short-circuit so that insertPack does not insert a duplicate
entry.

There is a possibility of hitting NPE on a logger if it is not the first
statically initialized member. For example, if another static
initializer creates an instance of its class and the logger is used
from the constructor.

So far we follow OSGi semantic versioning [1] which says the following:
"A change in the second (minor) part of the version signals that the
change is backward compatible with consumers of the API package but not
with the providers of that API. That is, when the API package goes from
version 1.5 to 1.6 it is no longer compatible with a provider of that
API but consumers of that API are backward compatible with that API
package."
The change Ib5fbf17bdaf727bc5d0e106ce88f2620d9f87a6f broke EMF Compare
which subclasses ResolveMerger since we added a new parameter to the
protected ResolveMerger.processEntry() method. According to the above
cited OSGi semantic versioning this is ok, implementers should expect
that they break on minor version changes of the API they implement.
This change reintroduces the old processEntry() method in order to help
avoid breakage for existing EMF Compare versions which expect breakage
also for the implementer case only for major version change (in this
case from JGit 4.x to 5.x).

This makes detection of binaries exact for ResolveMerger and
DiffFormatter: they will classify files as binary regardless of where
the '\0' occurs in the text.
