Apache HttpClient

HttpClient client = factory.getHttpClient(); //or any method to get a client instance
Credentials credentials = new UsernamePasswordCredentials(username, password);
client.getState().setCredentials(AuthScope.ANY, credentials);

HttpClient client = factory.getHttpClient(); //or any method to get a client instance

Git Annex

Posted on August 22, 2016August 22, 2016 by coder

What is Git Annex ?
git-annex is not a backup system. It may be a useful component of an archival system, or a way to deliver files to a backup system. For a backup system that uses git and that git-annex supports storing data in, see bup.git-annex is not a filesystem or Dropbox clone. However, the git-annex assistant is addressing some of the same needs in its own unique ways. (There is also a FUSE filesystem built on top of git-annex, called ShareBox.)

git-annex is not unison, but if you’re finding unison’s checksumming too slow, or its strict mirroring of everything to both places too limiting, then git-annex could be a useful alternative.

git-annex is also not a folder mirroring system like syncthing (although syncthing could be supported as a special remote) or gut, but it can be used to sync files such a way, with certain limitations (for example, it doesn’t like syncing .git directories so much).

git-annex is also not a distributed file system like Bittorrent or ipfs but both are supported as special remotes with more work in making git-annex more distributed underway.

git-annex is more than just a workaround for git scalability limitations that might eventually be fixed by efforts like git-bigfiles. In particular, git-annex’s location tracking allows having many repositories with a partial set of files, that are copied around as desired.

git-annex is not some flaky script that was quickly thrown together. I wrote it in Haskell because I wanted it to be solid and to compile down to a binary. And it has a fairly extensive test suite. (Don’t be fooled by “make test” only showing a few dozen test cases; each test involves checking dozens to hundreds of assertions.)

git-annex is not git-media, although they both approach the same problem from a similar direction. I only learned of git-media after writing git-annex, but I probably would have still written git-annex instead of using it. git-media uses git smudge filters (recently supported in git-annex as well; see unlocked files) and may be a tighter fit for certain situations. It lacks git-annex’s support for widely distributed storage, using only a single backend data store. It also does not support partial checkouts of file contents, like git-annex does.

git-annex is similarly not git-fat, which also uses git smudge filters, and also lacks git-annex’s widely distributed storage and partial checkouts.

Similarly, git-annex is not git-lfs, which also uses git smudge filters, and appears to lack git-annex’s widely distributed storage and partial checkouts.

git-annex is also not boar, although it shares many of its goals and characteristics. Boar implements its own version control system, rather than simply embracing and extending git. And while boar supports distributed clones of a repository, it does not support keeping different files in different clones of the same repository, which git-annex does, and is an important feature for large-scale archiving.

git-annex is not the Mercurial largefiles extension. Although mercurial and git have some of the same problems around large files, and both try to solve them in similar ways (standin files using mostly hashes of the real content).

* To install on debian :

Debian unstable and testing are usually fairly up to date, so this should be enough:

#Debian 7.0 "wheezy":

$sudo apt-get install git-annex
#

#Follow the instructions to enable backports.

$sudo apt-get -t wheezy-backports install git-annex
#Debian 6.0 "squeeze"

Follow the instructions to enable backports.

$sudo apt-get -t squeeze-backports install git-annex

Alice und Bob synchronisieren über SSH ihre Repositories.

Command Line :

git-annex Repo Alice
Alice erstellt sich in ihrem Verzeichnis annex eine git-annex Repository:

:~/annex$ git init
Initialized empty Git repository in /home/alice/annex/.git/
:~/annex$ git annex init "Alice"
init Alice ok
(Recording state in git...)
Sie fügt die Daten hinzu, die sie mit git-annex verwalten will:

:~/annex$ cp ~/Downloads/debhelper-slides.pdf .
:~/annex$ git annex add .
add debhelper-slides.pdf (checksum...) ok
(Recording state in git...)
:~/annex$ git commit -a -m "Added slides"
[master (root-commit) 761a810] Added slides
 1 file changed, 1 insertion(+)
 create mode 120000 debhelper-slides.pdf
Um sich mit Bob zu synchronisieren, fügt Sie dessen git-annex Repository als eine entferntes Repository hinzu:[3]

:~/annex$ git remote add bob ssh://bob@192.168.56.104/home/bob/annex
git-annex Repo Bob
Bob klont sich das vorhandene Repo von Alice und initialisiert sein git-annex Repository mit seinem Namen:

:~/annex$ git clone ssh://alice@192.168.56.1/home/alice/annex .

(Recording state in git...)
Er fügt ebenfalls Alice als Remote hinzu:

:~/annex$ git remote add alice ssh://alice@192.168.56.1/home/alice/annex
Alice und Bob synchronisieren sich
Alice und Bob können auf ihrer Seite über

git annex sync
ihre Repos aktualisieren und Neuerungen zum Partner pushen:

ok
Folgender find-Befehl listet gebrochene symbolische Links auf:

:~/annex$ find -L . -type l
./git-pkg-2011.pdf
Durch ein git annex get von Alice, kann er auch den Datei-Inhalt erhalten:

git-annex Repo Alice

Alice erstellt sich in ihrem Verzeichnis annex eine git-annex Repository:

:~/annex$ git init

Initialized empty Git repository in /home/alice/annex/.git/

:~/annex$ git annex init "Alice"

init Alice ok

(Recording state in git...)

Sie fügt die Daten hinzu, die sie mit git-annex verwalten will:

:~/annex$ cp ~/Downloads/debhelper-slides.pdf .

:~/annex$ git annex add .

add debhelper-slides.pdf (checksum...) ok

(Recording state in git...)

:~/annex$ git commit -a -m "Added slides"

[master (root-commit) 761a810] Added slides

1 file changed, 1 insertion(+)

create mode 120000 debhelper-slides.pdf

Um sich mit Bob zu synchronisieren, fügt Sie dessen git-annex Repository als eine entferntes Repository hinzu:[3]

:~/annex$ git remote add bob ssh://bob@192.168.56.104/home/bob/annex

git-annex Repo Bob

Bob klont sich das vorhandene Repo von Alice und initialisiert sein git-annex Repository mit seinem Namen:

:~/annex$ git clone ssh://alice@192.168.56.1/home/alice/annex .

Cloning into '.'...

Receiving objects: 100% (13/13), done.

Resolving deltas: 100% (2/2), done.

:~/annex$ git annex init "Bob"

init Bob ok

(Recording state in git...)

Er fügt ebenfalls Alice als Remote hinzu:

:~/annex$ git remote add alice ssh://alice@192.168.56.1/home/alice/annex

Alice und Bob synchronisieren sich

Alice und Bob können auf ihrer Seite über

git annex sync

ihre Repos aktualisieren und Neuerungen zum Partner pushen:

:~/annex$ git annex sync bob

commit

pull bob

* [new branch] git-annex -> synced/git-annex

* [new branch] master -> synced/master

Hat Alice neue Dateien hinzugefügt, erhält Bob im ersten Schritt nur einen gebrochenen symbolischen Link, ohne die eigentlichen Daten der Datei:

:~/annex$ git annex sync alice

(merging synced/git-annex origin/git-annex into git-annex...)

commit

pull alice

From ssh://192.168.56.1/home/alice/annex

* [new branch] git-annex -> alice/git-annex

* [new branch] master -> alice/master

* [new branch] synced/master -> alice/synced/master

Folgender find-Befehl listet gebrochene symbolische Links auf:

:~/annex$ find -L . -type l

./git-pkg-2011.pdf

Durch ein git annex get von Alice, kann er auch den Datei-Inhalt erhalten:

:~/annex$ git annex get .

get debhelper-slides.pdf (from alice...)

Wenn Bob synchronisiert hat ist die Datei inkl. Inhalt bei ihm angelangt. Ohne git annex copy hätte Bob wieder nur einen gebrochenen symbolischen Link vorgefunden:

:~/annex$ git annex sync

commit

pull origin

:~/annex$ ls

Da Alice die Datei kopiert, befindet sie sich nun bei Alice und Bob:

:~/annex$ git annex whereis .

Example Git Remote :

Examples

Add a new remote, fetch, and check out a branch from it

$ git remote
origin
$ git branch -r
  origin/HEAD -> origin/master
  origin/master
$ git remote add staging git://git.kernel.org/.../gregkh/staging.git
$ git remote
origin
staging
$ git fetch staging
...
From git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
 * [new branch]      master     -> staging/master
 * [new branch]      staging-linus -> staging/staging-linus
 * [new branch]      staging-next -> staging/staging-next
$ git branch -r
  origin/HEAD -> origin/master
  origin/master
  staging/master
  staging/staging-linus
  staging/staging-next
$ git checkout -b staging staging/master
...
Imitate git clone but track only selected branches

$ mkdir project.git
$ cd project.git
$ git init
$ git remote add -f -t master -m master origin git://example.com/git.git/
$ git merge origin
