3 | | -# Overview |
4 | | -Pk-vcs-git is lightweight library for execute basic Git VCS operations (merge, branch create etc). It uses [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) exposing IVCS implementation for Git repositories and [JGit](https://eclipse.org/jgit/) as framework to work with Git repositories. |
5 | | -Features: |
6 | | -- Branch create and remove |
7 | | -- Branch merge with result return (success or list of conflicted files) |
8 | | -- Branch commits messages list |
9 | | -- Summarized diff between branches |
10 | | -- Branches list |
11 | | -- File content getting and setting |
12 | | -- File create and remove |
13 | | - |
14 | | -# Terms |
15 | | -- Workspace Home |
16 | | - - Home folder of all folders used by vcs-related operations. See [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) for details |
17 | | -- Repository Workspace |
18 | | - - Folder for LWC folders related to Repository of one type. See [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) for details |
19 | | -- Locked Working Copy, LWC |
20 | | - - Folder where vcs-related operations are executed. Provides thread- and process-safe repository of working folders. See [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) for details |
21 | | -- Test Repository |
22 | | - - Git repository which is used to execute functional tests |
23 | | - - File-based repository is used |
24 | | - - Generates new before and deletes after each test |
25 | | - - Named randomly (uuid is used) |

27 | | -# Using pk-vcs-git |
28 | | -- Add github-hosted pk-vcs-git and pk-vcs-api projects as maven dependencies using [jitpack.io](https://jitpack.io/). As an example, add following to gradle.build file: |
29 | | - ```gradle |
30 | | - allprojects { |
31 | | - repositories { |
32 | | - maven { url "https://jitpack.io" } |
33 | | - } |
34 | | - } |
35 | | - |
36 | | - dependencies { |
37 | | - // versioning: master-SNAPSHOT (lastest build, unstable), + (lastest release, stable) or certain version (e.g. 1.1) |
38 | | - compile 'com.github.ProjectKaiser:pk-vcs-git:+' |
39 | | - compile 'com.github.ProjectKaiser:pk-vcs-api:+' |
40 | | - } |
41 | | - ``` |
42 | | - Or download release jars from https://github.com/ProjectKaiser/pk-vcs-git/releases, https://github.com/ProjectKaiser/pk-vcs-api/releases |
43 | | -- Create Workspace Home instance providing path to any folder as Workspace Home folder path. This folder will contain repositories folders (if different vcs or repositories are used) |
44 | | -```java |
45 | | - public static final String WORKSPACE_DIR = System.getProperty("java.io.tmpdir") + "git-workspaces"; |
46 | | - ... |
47 | | - IVCSWorkspace workspace = new VCSWorkspace(WORKSPACE_DIR); |
48 | | - ... |
49 | | -``` |
50 | | -- Obtain Repository Workspace from Workspace Home providing a certain Repository's url. The obtained Repository Workspace will represent a folder within Workspace Home dir which will contain all Working Copies relating to the provided VCS Repository |
51 | | -```java |
52 | | - String repoUrl = "https://github.com/ProjectKaiser/pk-vcs-api"; |
53 | | - IVCSRepositoryWorkspace repoWorkspace = workspace.getVCSRepositoryWorkspace(repoUrl); |
54 | | -``` |
55 | | -- Create `GitVCS` instance providing Repository Workspace |
56 | | -```java |
57 | | - IVCS vcs = new GitVCS(repoWorkspace); |
58 | | -``` |
59 | | -- Use methods of `IVCS` interface. See [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) for details |
60 | | -- Use `vcs.setProxy()` and `vcs.setCredentials()` if necessary |
61 | | - |
62 | | -# Implementation details |
63 | | -- [JGit](https://eclipse.org/jgit/) is used as framework to work with Git repositories |
64 | | -- [Github](https://github.com/) is used as hosting of a Test Repository |
65 | | -- LWC is obtained for each vcs operation. |
66 | | -- `getLocalGit(IVCSLockedWorkingCopy wc)` method is used to create a Git implementation to execute vcs operations within `wc` Working Copy |
67 | | - - If provided LWC is empty then current Test Repository is cloned into this LWC, otherwise just Git object is created |
68 | | -- If `IVCS.setProxy()` is called then provided proxy is used for each url which contains `repoUrl` |
69 | | - |
70 | | -# Functional testing |
71 | | -- New local file-based Test Repository is created before each test and deletes automatically after each test |
72 | | -- To execute tests just run GitVCSTest class as JUnit test. Tests from VCSAbstractTest class will be executed. See [pk-vcs-test](https://github.com/ProjectKaiser/pk-vcs-test) for details |
73 | | -- Run `gradle test` to execute tests |
74 | | - |
75 | | -# Limitations |
76 | | -- Commit messages can not be attached to branch create and delete operations because Git does not exposes these operations as separate commits |
