When a https connection could not be established because the SSL
handshake was unsuccessful, TransportHttp would unconditionally
throw a TransportException.
Other https clients like web browsers or also some SVN clients
handle this more gracefully. If there's a problem with the server
certificate, they inform the user and give him a possibility to
connect to the server all the same.
In git, this would correspond to dynamically setting http.sslVerify
to false for the server.
Implement this using the CredentialsProvider to inform and ask the
user. We offer three choices:
1. skip SSL verification for the current git operation, or
2. skip SSL verification for the server always from now on for
requests originating from the current repository, or
3. always skip SSL verification for the server from now on.
For (1), we just suppress SSL verification for the current instance of
TransportHttp.
For (2), we store a http.<uri>.sslVerify = false setting for the
original URI in the repo config.
For (3), we store the http.<uri>.sslVerify setting in the git user
config.
Adapt the SmartClientSmartServerSslTest such that it uses this
mechanism instead of setting http.sslVerify up front.
Improve SimpleHttpServer to enable setting it up also with HTTPS
support in anticipation of an EGit SWTbot UI test verifying that
cloning via HTTPS from a server that has a certificate that doesn't
validate pops up the correct dialog, and that cloning subsequently
proceeds successfully if the user decides to skip SSL verification.

Git has a rather elaborate mechanism to specify HTTP configuration
options per URL, based on pattern matching the URL against "http"
subsection names.[1] The URLs used for this matching are always the
original URLs; redirected URLs do not participate.
* Scheme and host must match exactly case-insensitively.
* An optional user name must match exactly.
* Ports must match exactly after default ports have been filled in.
* The path of a subsection, if any, must match a segment prefix of
the path of the URL.
* Matches with user name take precedence over equal-length path
matches without, but longer path matches are preferred over
shorter matches with user name.
Implement this for JGit. Factor out the HttpConfig from TransportHttp
and implement the matching and override mechanism.
The set of supported settings is still the same; JGit currently
supports only followRedirects, postBuffer, and sslVerify, plus the
JGit-specific maxRedirects key.
Add tests for path normalization and prefix matching only on segment
separators, and use the new mechanism in SmartClientSmartServerSslTest
to disable sslVerify selectively for only the test server URLs.
Compare also bug 374703 and bug 465492. With this commit it would be
possible to set sslVerify to false for only the git server using a
self-signed certificate instead of having to switch it off globally
via http.sslVerify.

With atomic ref updates using packed refs, JGit did not fire a
RefsChangedEvent. This resulted in a user-visible regression in
EGit: the UI would not update after a "Fetch from upstream...".
Presumably it would also make Gerrit miss out on ref changes?
Strengthen the BatchRefUpdateTest by also asserting the expected
number of RefsChangedEvents, and ensure modCnt is incremented in
RefDirectory.commitPackedRefs() when refs really changed (as opposed
to some internal housekeeping operation, such as packing loose refs).

An application can choose to invoke setAdvertisedRefs multiple times,
for example several AdvertiseRefsHook installed in a chain. Each of
these invocations populates the advertisedHaves collection with the
unique set of ObjectIds.
This can lead to a server over-advertising with ".have" lines if the
first hook pushes in a lot of references, and the second hook filters
this to a subset. ReceivePack will advertise the unique objects from
the first hook using ".have" lines, which may lead to a huge
advertisement sent to the client.
This can also contribute to a very slow connectivity check after the
pack is parsed as ReceivePack calls markUninteresting on every commit
in advertisedHaves. This may require expanding a lot of subtrees to
mark all trees as uninteresting as well. On a very big repository
this can lead to a many-second stall.
Clear the advertisedHaves collection any time the refs are updated.
Add a test to verify the correct set of objects was sent.

If a ReftableConfig has been supplied by the caller, write out a
reftable as a sibling of the the GC pack, alongside the heads.
To bootstrap from a non-reftable system, the refs are read from the
DfsRefDatabase if no GC reftables are present. Its assumed the
references are fully current, and do not need to be merged with any
other reftables. Any non-GC reftables will be pruned at the end of
the GC cycle, just like any packs that were replaced.
If a GC reftable is present, all existing reftables are compacted, and
references from DfsRefDatabase are only used to seed the packer. Its
assumed these are consistent with each other.

Don't convert a lot of ObjectId to String stored in generic

Instead rely on "this" from the FsckPackParser to lookup information

Hence revert the save action "Convert control statement bodies to

the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.

Some repositories can have a policy that do not accept certain blobs. To
check if the incoming pack file contains such blobs, ObjectChecker can
be used. However, this ObjectChecker is not called by PackParser if the
blob is stored as a whole. This is because the object can be so large
that it doesn't fit in memory.
This change introduces BlobObjectChecker. This interface takes chunks of
a blob instead of the entire object. ObjectChecker can optionally return
a BlobObjectChecker. This won't change existing ObjectChecker
implementation; existing implementation continues to receive deltified
blob objects only.

Path pattern matching for attribute rules is different than matching
for excluded files.
The first difference concerns patterns without slashes. For
gitattributes those must match on the last component only, not on
any earlier segment. This is true also for directory-only patterns.
The second difference concerns directory-only patterns. Those also
must not match on a prefix or segment except the last one. They do
not apply recursively to all files beneath.
And third, matches only on a prefix must match for gitattributes
only if the last matcher was "/**".
Add a new parameter for such path matching to IMatcher.matches() and
pass it through as appropriate (false for gitignore, true for
gitattributes). As far as gitignore is concerned, there is no change.
New tests have been added, and some existing attribute matching tests
have been fixed since they operated on wrong assumptions.

Make the handling of typed values somewhat configurable by using
a separate converter. The default converter is the same as before;
just the implementations of the getters were moved. They also still
raise IllegalArgumentException on invalid values as before.
The converter can be set globally via Config.setTypedConfigGetter(),
which EGit can use in its core Activator to plug in a variant that
catches the IllegalArgumentException, logs the problem, and then
returns the default value.
In this way the behavior for other users of the JGit library is
unchanged, while EGit can deal gracefully with invalid git configs.

Ensure the Jsch instance used knows about ~/.ssh/config. This
enables Jsch to honor more user configurations (see
com.jcraft.jsch.Session.applyConfig()), in particular also the
UserKnownHostsFile configuration, or additional identities given
via multiple IdentityFile entries.
Turn JGit's OpenSshConfig into a full parser that can be a
Jsch-compliant ConfigRepository. This avoids a few bugs
in Jsch's OpenSSHConfig and keeps the JGit-facing interface
unchanged. At the same time we can supply a JGit OpenSshConfig
instance as a ConfigRepository to Jsch. And since they'll both
work from the same object, we can also be sure that the parsing
behavior is identical.
The parser does not handle the "Match" and "Include" keys, and it
doesn't do %-token substitutions (yet).
Note that Jsch doesn't handle multi-valued UserKnownHostFile
entries as known by modern OpenSSH.[1]
