You do not need an svn login if you have direct file access to the svn database. Somewhere on the server you have the root of the svn database, say directory /some/dir. It has subdirectories db, conf, hooks and locks. I am using SVN and have a repository on a remote machine. Sometimes, when working on my local machine I realize that I need to add some new files to the repo.

Subversion (SVN) is a version control software that allows users to download the very latest version of a branch, without having to wait for someone to get around to packaging it. Advantages to using Subversion include the latest version, vastly simplified updating, the ability to roll back an upgrade, the ability to create and submit patches.

See Subversion for more details; below are some quick directions for a couple common tasks.

• 1Using Subversion to download MediaWiki

Using Subversion to download MediaWiki

Prerequisites

You must have a Subversion client installed before you can use it. (Although you can theoretically download files without Subversion, this would mean tediously downloading each individual file manually.) The recommended software is the official Subversion client, available from the Subversion project page. Note that this client uses a command-line interface, which the instructions below use. Alternatively, you can get subversioning software with a graphical user interface such as TortoiseSVN.

Download

You can download from any branch and module (before MediaWiki 1.18.2) in MediaWiki SVN.

• Modules: The two modules important to web applications are phase3 (the main application) and extensions (extension code).
• Branches: Named release branches use the naming scheme REL$1_$2[_$3], where $1 is the MediaWiki version, $2 is a major version and $3 is a minor revision. For example, version 1.6.3 is branch REL1_6_3, the latest 1.6 is REL1_6, 1.5.8 is REL1_5_8, and the latest (untagged) would be HEAD.

To download from the latest 1.33 release (recommended), use Git, not Subversion. To get MediaWiki 1.18.1 (not recommended) enter the following command from the command-line in the directory you wish to download to:

Alternately, you can download the last development version left behind in subversion using the following command:

To get the latest skins directory (as of MediaWiki 1.18.1) including the Vector skin, use this line:

To check out an extension like Extension:TitleKey to your folder '$IP/extensions/TitleKey':

Using TortoiseSVN

TortoiseSVN is a convenient SVN client for Windows that integrates with Windows Explorer.

• Go to Windows Explorer (hit WIN+E or right-click on the Start button and click Explore), and create a new folder in a location of your choice. You may want to name it something like 'MediaWiki Repository.'
• Right click on that folder and TortoiseSVN -> Create repository here.
• Right click on that folder again and click SVN Checkout; DO NOT CLICK 'IMPORT'.
• For the 'URL of repository,' put http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3/
• The checkout directory should automatically populate to the mediawiki subfolder of your repository folder.
• Click OK.

Installing

Normal installation rules apply. However, for best results, use PHP 5.3.3 as an Apache module.

Upgrading and downgrading

Upgrading between releases with SVN is simple. If you have direct access to the command-line on the server, you can enter the commands below directly; alternatively, you can maintain a copy on a local machine and upload updated versions to the server.

To upgrade MediaWiki, simply use the command below in the root of the installation directory. Note that this will upgrade to the latest version of the current major version. If you are using MediaWiki 1.6, this will upgrade to any version 1.6.x, but not to 1.7:

To upgrade to another release branch (version 1.7 in the example below) or to switch between individually-selected version tags, you can use the 'switch' command (substituting the appropriate versions):

Don't forget to run maintenance/update.php every once in a while, especially if things start acting strangely.

Svn Repo Browser

Apache Subversion (often abbreviated SVN, after its command name svn) is a software versioning and revision control system distributed as open source under the Apache License.^[2] Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS).

The open source community has used Subversion widely: for example in projects such as Apache Software Foundation, Free Pascal, FreeBSD, GCC and SourceForge. CodePlex was previously a common host for Subversion repositories.

Subversion was created by CollabNet Inc. in 2000, and is now a top-level Apache project being built and used by a global community of contributors.

History[edit]

CollabNet founded the Subversion project in 2000 as an effort to write an open-source version-control system which operated much like CVS but which fixed the bugs and supplied some features missing in CVS.^[3] By 2001, Subversion had advanced sufficiently to host its own source code,^[3] and in February 2004, version 1.0 was released.^[4] In November 2009, Subversion was accepted into Apache Incubator: this marked the beginning of the process to become a standard top-level Apache project.^[5] It became a top-level Apache project on February 17, 2010.^[6]

Release dates are extracted from Apache Subversion's CHANGES file,^[19] which records all release history.

Features[edit]

• Commits as true atomic operations (interrupted commit operations in CVS would cause repository inconsistency or corruption).
• Renamed/copied/moved/removed files retain full revision history.
• The system maintains versioning for directories, renames, and file metadata (but not for timestamps). Users can move and/or copy entire directory-trees very quickly, while retaining full revision history.
• Versioning of symbolic links.
• Native support for binary files, with space-efficient binary-diff storage.
• Apache HTTP Server as network server, WebDAV/Delta-V for protocol. There is also an independent server process called svnserve that uses a custom protocol over TCP/IP.
• Branching is a cheap operation, independent of file size (though Subversion itself does not distinguish between a branch and a directory)
• Natively client–server, layeredlibrary design.
• Client/server protocol sends diffs in both directions.
• Costs proportional to change size, not to data size.
• Parsable output, including XML log output.
• open source licensed – Apache License since the 1.7 release; prior versions use a derivative of the Apache Software License 1.1.
• Internationalized program messages.
• File locking for unmergeable files ('reserved checkouts').
• Path-based authorization.
• Language bindings for C#, PHP, Python, Perl, Ruby, and Java.
• Full MIME support – users can view or change the MIME type of each file, with the software knowing which MIME types can have their differences from previous versions shown.
• Merge tracking – Merges between branches will be tracked, this allows automatic merging between branches without telling Subversion what does and does not need to be merged.
• Changelists to organize commits into commit groups.

Repository types[edit]

Subversion offers two types of repository storage.

Berkeley DB (deprecated^[20])[edit]

The original development of Subversion used the Berkeley DB package.Subversion has some limitations with Berkeley DB usage when a program that accesses the database crashes or terminates forcibly. No data loss or corruption occurs, but the repository remains offline while Berkeley DB replays the journal and cleans up any outstanding locks. The safest way to use Subversion with a Berkeley DB repository involves a single server-process running as one user (instead of through a shared filesystem).^[21]

FSFS[edit]

In 2004, a new storage subsystem was developed and named FSFS.It works faster than the Berkeley DB backend on directories with a large number of files and takes less disk space,due to less logging.^[21]

Beginning with Subversion 1.2, FSFS became the default data store for new repositories.

The etymology of 'FSFS' is based on Subversion's use of the term 'filesystem' for its repository storage system.FSFS stores its contents directly within the operating system's filesystem, rather than a structured system like Berkeley DB.Thus, it is a '[Subversion] FileSystem atop the FileSystem'.

FSX[edit]

A new file system, called FSX, is under development to remove some limitations of FSFS. As of Version 1.9, it was not considered production-ready.^[22]

Repository access[edit]

Access to Subversion repositories can take place by:

1. Local filesystem or network filesystem,^[23] accessed by client directly. This mode uses the file:///path access scheme.
2. WebDAV/Delta-V (over http or https) using the mod_dav_svn module for Apache 2. This mode uses the http://host/path access scheme or https://host/path for secure connections using ssl.
3. Custom 'svn' protocol (default port 3690), using plain text or over TCP/IP. This mode uses either the svn://host/path access scheme for unencrypted transport or svn+ssh://host/path scheme for tunneling over ssh.

All three means can access both FSFS and Berkeley DB repositories.

Any 1.x version of a client can work with any 1.x server. Newer clients and servers have additional features and performance capabilities, but have fallback support for older clients/servers.^[24]

Layers[edit]

Internally, a Subversion system comprises several libraries arranged as layers. Each performs a specific task and allows developers to create their own tools at the desired level of complexity and specificity.

Fs

The lowest level; it implements the versioned filesystem which stores the user data.

Repos

Concerned with the repository built up around the filesystem. It has many helper functions and handles the various 'hooks' that a repository may have, e.g., scripts that run when an action is performed. Together, Fs and Repos constitute the 'filesystem interface'.

mod_dav_svn

Provides WebDAV/Delta-V access through Apache 2.

Ra

Handles 'repository access', both local and remote. From this point on, repositories are referred to using URLs, e.g.

• file:///path/ for local access,
• http://host/path/ or https://host/path/ for WebDAV access, or
• svn://host/path/ or svn+ssh://host/path/ for the SVN protocol.

Client, Wc

The highest level. It abstracts repository access and provides common client tasks, such as authenticating users or comparing versions. Subversion clients use the Wc library to manage the local working copy.

Filesystem[edit]

One can view the Subversion filesystem as 'two-dimensional'.^[25] Two coordinates are used to unambiguously address filesystem items:

• Path (regular path of Unix-like OS filesystem)
• Revision

Each revision in a Subversion filesystem has its own root, which is used to access contents at that revision. Files are stored as links to the most recent change; thus a Subversion repository is quite compact. The system consumes storage space proportional to the number of changes made, not to the number of revisions.

The Subversion filesystem uses transactions to keep changes atomic. A transaction operates on a specified revision of the filesystem, not necessarily the latest. The transaction has its own root, on which changes are made. It is then either committed and becomes the latest revision, or is aborted. The transaction is actually a long-lived filesystem object; a client does not need to commit or abort a transaction itself, rather it can also begin a transaction, exit, and then can re-open the transaction and continue using it. Potentially, multiple clients can access the same transaction and work together on an atomic change, though no existing clients expose this capability.

Properties[edit]

One important feature of the Subversion filesystem is properties: simple name=value pairs of text. Most properties occur on filesystem entries (i.e., files and directories). These are versioned just like other changes to the filesystem. The Subversion client reserves the 'svn:' prefix for built-in properties, but other names can be used to define custom properties.

svn:executable

Makes a file on Unix-hosted working copies executable, when supported by the filesystem.

svn:mime-type

Stores the Internet media type ('MIME type') of a file. Affects the handling of diffs and merging.

svn:ignore

A list of filename patterns to ignore in a directory. Similar to CVS's .cvsignore file.

svn:keywords

A list of keywords to substitute into a file when changes are made. The file itself must also reference the keywords as $keyword$ or $keyword:...$. This is used to maintain certain information (e.g., author, date of last change, revision number) in a file without human intervention.
The keyword substitution mechanism originates from RCS and from CVS.^[26]

svn:eol-style

Makes the client convert end-of-line characters in text files. Used when the working copy is needed with a specific EOL style. 'native' is commonly used, so that EOLs match the user's OS EOL style. Repositories may require this property on all files to prevent inconsistent line endings, which can cause a problem in itself.

svn:externals

Allows parts of other repositories to be automatically checked out into a subdirectory.

svn:needs-lock

Specifies that a file is to be checked out with file permissions set to read-only. This is designed for use with the locking mechanism. The read-only permission reminds one to obtain a lock before modifying the file: obtaining a lock makes the file writable, and releasing the lock makes it read-only again. Locks are only enforced during a commit operation. Locks can be used without setting this property. However, that is not recommended, because it introduces the risk of someone modifying a locked file; they will only discover it has been locked when their commit fails.

svn:special

This property is not meant to be set or modified directly by users. As of 2010 it is only used for having symbolic links in the repository. When a symbolic link is added to the repository, a file containing the link target is created with this property set. When a Unix-like system checks out this file, the client converts it to a symbolic link.

svn:mergeinfo

Used to track merge data (revision numbers) in Subversion 1.5 (or later). This property is automatically maintained by the merge command, and it is not recommended to change its value manually.^[27]

Subversion also uses properties on revisions themselves. Like the above properties on filesystem entries, the names are completely arbitrary, with the Subversion client using certain properties prefixed with 'svn:'. However, these properties are not versioned, and they can be changed later if allowed by a pre-revprop-change hook.^[28]

svn:date

The date and time stamp of a revision.

svn:author

The name of the user that submitted the change(s).

svn:log

The user-supplied description of the change(s).

Branching and tagging[edit]

Subversion uses the inter-file branching model from Perforce^[29] to implement branches and tagging. A branch is a separate line of development.^[30] Tagging refers to labeling the repository at a certain point in time so that it can be easily found in the future. In Subversion, the only difference between branches and tags is how they are used.

A new branch or tag is set up by using the 'svn copy' command, which should be used in place of the native operating system mechanism. The copied directory is linked to the original in the repository to preserve its history, and the copy takes very little extra space in the repository.

All the versions in each branch maintain the history of the file up to the point of the copy, plus any changes made since. One can 'merge' changes back into the trunk or between branches.

Limitations and problems[edit]

A known problem in Subversion affects the implementation of the file and directory rename operation. As of 2014, Subversion implements the renaming of files and directories as a 'copy' to the new name followed by a 'delete' of the old name. Only the names change, all data relating to the edit history remains the same, and Subversion will still use the old name in older revisions of the 'tree'. However, Subversion may become confused when a move conflicts with edits made elsewhere,^[31] both for regular commits and when merging branches.^[32] The Subversion 1.5 release addressed some of these scenarios while others remained problematic.^[33] The Subversion 1.8 release addressed some of these problems by making moves a first-class operation on the client, but it is still treated as copy+delete in the repository.^[34]

As of 2013, Subversion lacks some repository-administration and management features. For instance, someone may wish to edit the repository to permanently remove all historical records of certain data. Subversion does not have built-in support to achieve this simply.^[35]

Subversion stores additional copies of data on the local machine, which can become an issue with very large projects or files, or if developers work on multiple branches simultaneously. In versions prior to 1.7 these .svn directories on the client side could become corrupted by ill-advised user activity like global search/replace operations.^[36] Starting with version 1.7 Subversion uses a single centralized .svn folder per working area.^[37]

Subversion does not store the modification times of files. As such, a file checked out of a Subversion repository will have the 'current' date (instead of the modification time in the repository), and a file checked into the repository will have the date of the check-in (instead of the modification time of the file being checked in). This might not always be what is wanted.^[38]To mitigate this, third-party tools exist that allow for preserving modification time and other filesystem meta-data.^[39][40]However, giving checked out files a current date is important as well — this is how tools like make(1) will take notice of a changed file for rebuilding it.

Subversion uses a centralized revision control model. Ben Collins-Sussman, one of the designers of Subversion, believes a centralised model would help prevent 'insecure programmers' from hiding their work from other team members.^[41] Some users of version control systems see the centralised model as detrimental; famously, Linus Torvalds attacked Subversion's model and its developers.^[42]

Subversion often does not deal well with the filename normalization performed by the HFS+ filesystem. This can cause problems when files with accented characters in their names are added to the repository on a non-HFS+ filesystem and the repository is then used with HFS+.^[43]

Subversion tags and branches[edit]

Revision numbers are difficult to remember in any version-control system. For this reason, most systems offer symbolic tags as user-friendly references to them. Subversion does not have such a feature and what its documentation recommends to use instead is very different in nature. Instead of implementing tags as references to points in history, Subversion recommends making snapshot copies into a well-known subdirectory ('tags/') in the space of the repository tree. Only a few predefined references are available: HEAD, BASE, PREV and COMMITTED.

This history-to-space projection has multiple issues:

1. When a snapshot is taken, the system does not assign any special meaning to the name of the tag/snapshot. This is the difference between a copy and a reference. The revision is recorded and the snapshot can be accessed by URL. This makes some operations less convenient and others impossible. For instance, a naïve svn diff -r tag1:tag2 myfile does not work; it is slightly more complicated than that to achieve, requiring the user to know and input URL/paths to the snapshots instead of just the names: svn diff <URL-TO-TAG1>/myfile <URL-TO-TAG2>/myfile. Other operations like for instance svn log -r tag1:tag2 myfile are just impossible.

2. When two (ideally independent) object types live in the repository tree, a 'fight to the top' can ensue. In other words, it is often difficult to decide at which level to create the 'tags/' subdirectory:

3. Tags, by their conventional definition are both read-only and light-weight, on the repository and client. Subversion copies are not read-only, and while they are light-weight on the repository, they are incredibly heavy-weight on the client.

To address such issues, posters on the Subversion mailing lists have suggested a new feature called 'labels' or 'aliases'.^{[44][full citation needed]}SVN labels would more closely resemble the 'tags' of other systems such as CVS or Git. The fact that Subversion has global revision numbers opens the way to a very simple label → revision implementation. Yet as of 2013, no progress has been made and symbolic tags are not in the list of the most wanted features.^[45]

Development and implementation[edit]

CollabNet has continued its involvement with Subversion, but the project runs as an independent open source community. In November 2009, the project was accepted into the Apache Incubator, aiming to become part of the Apache Software Foundation's efforts.^[46] Since March 2010, the project is formally known as Apache Subversion, being a part of the Apache Top-Level Projects.^[47]

In October 2009, WANdisco announced the hiring of core Subversion committers as the company moved to become a major corporate sponsor of the project. This included Hyrum Wright, president of the Subversion Corporation and release manager for the Subversion project since early 2008, who joined the company to lead its open source team.^[48]

The Subversion open-source community does not provide binaries, but potential users can download binaries from volunteers.^[49] While the Subversion project does not include an official graphical user interface (GUI) for use with Subversion, third parties have developed a number of different GUIs, along with a wide variety of additional ancillary software.

Convert Svn Repo To Git

Work announced in 2009 included SubversionJ (a Java API) and implementation of the Obliterate command, similar to that provided by Perforce. Both of these enhancements were sponsored by WANdisco.^[50]

The Subversion committers normally have at least one or two new features under active development at any one time. The 1.7 release of Subversion in October 2011 included a streamlined HTTP transport to improve performance and a rewritten working-copy library.^[51]
