Macro Definition Documentation

#define FALSE   0

uhh...

false

Definition at line 103 of file svn_types.h.

#define SVN__APR_STATUS_IS_ENOTDIR (   s)    APR_STATUS_IS_ENOTDIR(s)

On Windows, APR_STATUS_IS_ENOTDIR includes several kinds of invalid-pathname error but not ERROR_INVALID_NAME, so we include it.

We also include ERROR_DIRECTORY as that was not included in apr versions before 1.4.0 and this fix is not backported

Definition at line 215 of file svn_types.h.

#define SVN__APR_STATUS_IS_EPIPE (   s)    APR_STATUS_IS_EPIPE(s)

On Windows, APR_STATUS_IS_EPIPE does not include ERROR_NO_DATA error.

So we include it.

Definition at line 226 of file svn_types.h.

#define SVN_DEPRECATED

Macro used to mark deprecated functions.

Since
New in 1.6.

Definition at line 59 of file svn_types.h.

#define SVN_DEPTH_INFINITY_OR_EMPTY (   recurse)    ((recurse) ? svn_depth_infinity : svn_depth_empty)

Return svn_depth_infinity if boolean recurse is TRUE, else return svn_depth_empty.

Note
New code should never need to use this, it is called only from pre-depth APIs, for compatibility.
Since
New in 1.5.

Definition at line 525 of file svn_types.h.

#define SVN_DEPTH_INFINITY_OR_FILES (   recurse)    ((recurse) ? svn_depth_infinity : svn_depth_files)

Return svn_depth_infinity if boolean recurse is TRUE, else return svn_depth_files.

Note
New code should never need to use this, it is called only from pre-depth APIs, for compatibility.
Since
New in 1.5.

Definition at line 503 of file svn_types.h.

#define SVN_DEPTH_INFINITY_OR_IMMEDIATES (   recurse)    ((recurse) ? svn_depth_infinity : svn_depth_immediates)

Return svn_depth_infinity if boolean recurse is TRUE, else return svn_depth_immediates.

Note
New code should never need to use this, it is called only from pre-depth APIs, for compatibility.
Since
New in 1.5.

Definition at line 514 of file svn_types.h.

#define SVN_DEPTH_IS_RECURSIVE (   depth)    ((depth) == svn_depth_infinity || (depth) == svn_depth_unknown)

Return a recursion boolean based on depth.

Although much code has been converted to use depth, some code still takes a recurse boolean. In most cases, it makes sense to treat unknown or infinite depth as recursive, and any other depth as non-recursive (which in turn usually translates to svn_depth_files).

Definition at line 535 of file svn_types.h.

#define SVN_FILESIZE_T_FMT   APR_INT64_T_FMT

In printf()-style functions, format file sizes using this.

Definition at line 409 of file svn_types.h.

#define SVN_INVALID_FILESIZE   ((svn_filesize_t) -1)

The 'official' invalid file size constant.

Definition at line 406 of file svn_types.h.

#define SVN_LINENUM_MAX_VALUE   ULONG_MAX

The maximum value of an svn_linenum_t.

Since
New in 1.7.

Definition at line 1264 of file svn_types.h.

#define SVN_MAX_OBJECT_SIZE   (((apr_size_t) -1) / 2)

The maximum amount we can ever hold in memory.

Definition at line 1057 of file svn_types.h.

#define SVN_REVNUM_T_FMT   "ld"

Originally intended to be used in printf()-style functions to format revision numbers.

Deprecated due to incompatibilities with language translation tools (e.g. gettext).

New code should use a bare "%ld" format specifier for formatting revision numbers.

Deprecated:
Provided for backward compatibility with the 1.0 API.

Definition at line 398 of file svn_types.h.

#define SVN_STR_TO_REV (   str)    ((svn_revnum_t) atol(str))

Convert NULL-terminated C string str to a revision number.

Definition at line 371 of file svn_types.h.

#define SVN_STREAM_CHUNK_SIZE   102400

A buffer size that may be used when processing a stream of data.

Note
We don't use this constant any longer, since it is considered to be unnecessarily large.
Deprecated:
Provided for backwards compatibility with the 1.3 API.

Definition at line 1039 of file svn_types.h.

#define SVN_UNALIGNED_ACCESS_IS_OK   0

Indicate whether the current platform supports unaligned data access.

On the majority of machines running SVN (x86 / x64), unaligned access is much cheaper than repeated aligned access. Define this macro to 1 on those machines. Unaligned access on other machines (e.g. IA64) will trigger memory access faults or simply misbehave.

Note: Some platforms may only support unaligned access for integers (PowerPC). As a result this macro should only be used to determine if unaligned access is supported for integers.

Since
New in 1.7.

#define TRUE   1

uhh...

true

Definition at line 98 of file svn_types.h.

Typedef Documentation

typedef svn_error_t*(* svn_cancel_func_t)(void *cancel_baton)

A user defined callback that subversion will call with a user defined baton to see if the current operation should be continued.

If the operation should continue, the function should return SVN_NO_ERROR, if not, it should return SVN_ERR_CANCELLED.

Definition at line 1098 of file svn_types.h.

typedef svn_error_t*(* svn_commit_callback2_t)(const svn_commit_info_t *commit_info, void *baton, apr_pool_t *pool)

Callback function type for commits.

When a commit succeeds, an instance of this is invoked with the commit_info, along with the baton closure. pool can be used for temporary allocations.

Since
New in 1.4.

Definition at line 1014 of file svn_types.h.

typedef svn_error_t*(* svn_commit_callback_t)(svn_revnum_t new_revision, const char *date, const char *author, void *baton)

Same as svn_commit_callback2_t, but uses individual data elements instead of the svn_commit_info_t structure.

Deprecated:
Provided for backward compatibility with the 1.3 API.

Definition at line 1024 of file svn_types.h.

All information about a commit.

Note
Objects of this type should always be created using the svn_create_commit_info() function.
Since
New in 1.3.
typedef enum svn_depth_t svn_depth_t

The concept of depth for directories.

Note
This is similar to, but not exactly the same as, the WebDAV and LDAP concepts of depth.
Since
New in 1.5.
typedef struct svn_dirent_t svn_dirent_t

A general subversion directory entry.

Note
To allow for extending the svn_dirent_t structure in future releases, always use svn_dirent_create() to allocate the stucture.
Since
New in 1.6.
typedef struct svn_error_t svn_error_t

Subversion error object.

Defined here, rather than in svn_error.h, to avoid a recursive #include situation.

typedef apr_int64_t svn_filesize_t

The size of a file in the Subversion FS.

Definition at line 403 of file svn_types.h.

typedef unsigned long svn_linenum_t

A line number, such as in a file or a stream.

Since
New in 1.7.

Definition at line 1258 of file svn_types.h.

typedef struct svn_lock_t svn_lock_t

A lock object, for client & server to share.

A lock represents the exclusive right to add, delete, or modify a path. A lock is created in a repository, wholly controlled by the repository. A "lock-token" is the lock's UUID, and can be used to learn more about a lock's fields, and or/make use of the lock. Because a lock is immutable, a client is free to not only cache the lock-token, but the lock's fields too, for convenience.

Note that the 'is_dav_comment' field is wholly ignored by every library except for mod_dav_svn. The field isn't even marshalled over the network to the client. Assuming lock structures are created with apr_pcalloc(), a default value of 0 is universally safe.

Note
in the current implementation, only files are lockable.
Since
New in 1.2.

A structure to represent a path that changed for a log entry.

Note
To allow for extending the svn_log_changed_path2_t structure in future releases, always use svn_log_changed_path2_create() to allocate the structure.
Since
New in 1.6.

A structure to represent a path that changed for a log entry.

Same as the first three fields of svn_log_changed_path2_t.

Deprecated:
Provided for backward compatibility with the 1.5 API.
typedef svn_error_t*(* svn_log_entry_receiver_t)(void *baton, svn_log_entry_t *log_entry, apr_pool_t *pool)

The callback invoked by log message loopers, such as svn_ra_plugin_t.get_log() and svn_repos_get_logs().

This function is invoked once on each log message, in the order determined by the caller (see above-mentioned functions).

baton is what you think it is, and log_entry contains relevant information for the log message. Any of log_entry->author, log_entry->date, or log_entry->message may be NULL.

If log_entry->date is neither NULL nor the empty string, it was generated by svn_time_to_cstring() and can be converted to apr_time_t with svn_time_from_cstring().

If log_entry->changed_paths is non-NULL, then it contains as keys every path committed in log_entry->revision; the values are (svn_log_changed_path_t *) structures.

If log_entry->has_children is TRUE, the message will be followed immediately by any number of merged revisions (child messages), which are terminated by an invocation with SVN_INVALID_REVNUM. This usage may be recursive.

Use pool for temporary allocation. If the caller is iterating over log messages, invoking this receiver on each, we recommend the standard pool loop recipe: create a subpool, pass it as pool to each call, clear it after each iteration, destroy it after the loop is done. (For allocation that must last beyond the lifetime of a given receiver call, use a pool in baton.)

Since
New in 1.5.

Definition at line 984 of file svn_types.h.

A structure to represent all the information about a particular log entry.

Note
To allow for extending the svn_log_entry_t structure in future releases, always use svn_log_entry_create() to allocate the structure.
Since
New in 1.5.
typedef svn_error_t*(* svn_log_message_receiver_t)(void *baton, apr_hash_t *changed_paths, svn_revnum_t revision, const char *author, const char *date,const char *message, apr_pool_t *pool)

Similar to svn_log_entry_receiver_t, except this uses separate parameters for each part of the log entry.

Deprecated:
Provided for backward compatibility with the 1.4 API.

Definition at line 995 of file svn_types.h.

Mergeinfo representing a merge of a range of revisions.

Since
New in 1.5

The various types of nodes in the Subversion filesystem.

typedef long int svn_revnum_t

About Special Files in Subversion.

Subversion denotes files that cannot be portably created or modified as "special" files (svn_node_special). It stores these files in the repository as a plain text file with the svn:special property set. The file contents contain: a platform-specific type string, a space character, then any information necessary to create the file on a supported platform. For example, if a symbolic link were being represented, the repository file would have the following contents:

"link /path/to/link/target"

Where 'link' is the identifier string showing that this special file should be a symbolic link and '/path/to/link/target' is the destination of the symbolic link.

Special files are stored in the text-base exactly as they are stored in the repository. The platform specific files are created in the working copy at EOL/keyword translation time using svn_subst_copy_and_translate2(). If the current platform does not support a specific special file type, the file is copied into the working copy as it is seen in the repository. Because of this, users of other platforms can still view and modify the special files, even if they do not have their unique properties.

New types of special files can be added by:

  1. Implementing a platform-dependent routine to create a uniquely named special file and one to read the special file in libsvn_subr/io.c.
  2. Creating a new textual name similar to SVN_SUBST__SPECIAL_LINK_STR in libsvn_subr/subst.c.
  3. Handling the translation/detranslation case for the new type in create_special_file and detranslate_special_file, using the routines from 1.A revision number.

Generic three-state property to represent an unknown value for values that are just like booleans.

The values have been set deliberately to make tristates disjoint from svn_boolean_t.

Note
It is unsafe to use apr_pcalloc() to allocate these, since '0' is not a valid value.

Enumeration Type Documentation

The concept of depth for directories.

Note
This is similar to, but not exactly the same as, the WebDAV and LDAP concepts of depth.
Since
New in 1.5.
Enumerator
svn_depth_unknown 

Depth undetermined or ignored.

In some contexts, this means the client should choose an appropriate default depth. The server will generally treat it as svn_depth_infinity.

svn_depth_exclude 

Exclude (i.e., don't descend into) directory D.

Note
In Subversion 1.5, svn_depth_exclude is not supported anywhere in the client-side (libsvn_wc/libsvn_client/etc) code; it is only supported as an argument to set_path functions in the ra and repos reporters. (This will enable future versions of Subversion to run updates, etc, against 1.5 servers with proper svn_depth_exclude behavior, once we get a chance to implement client-side support for svn_depth_exclude.)
svn_depth_empty 

Just the named directory D, no entries.

Updates will not pull in any files or subdirectories not already present.

svn_depth_files 

D + its file children, but not subdirs.

Updates will pull in any files not already present, but not subdirectories.

svn_depth_immediates 

D + immediate children (D and its entries).

Updates will pull in any files or subdirectories not already present; those subdirectories' this_dir entries will have depth-empty.

svn_depth_infinity 

D + all descendants (full recursion from D).

Updates will pull in any files or subdirectories not already present; those subdirectories' this_dir entries will have depth-infinity. Equivalent to the pre-1.5 default update behavior.

Since
New in 1.4.
svn_commit_info_t* svn_create_commit_info ( apr_pool_t *  pool)

Allocate an object of type svn_commit_info_t in pool and return it.

The revision field of the new struct is set to SVN_INVALID_REVNUM. All other fields are initialized to NULL.

Note
Any object of the type svn_commit_info_t should be created using this function. This is to provide for extending the svn_commit_info_t in the future.
Since
New in 1.3.
svn_depth_t svn_depth_from_word ( const char *  word)

Return the appropriate depth for depth_str.

word is as returned from svn_depth_to_word(). If depth_str does not represent a recognized depth, return svn_depth_unknown.

Since
New in 1.5.
const char* svn_depth_to_word ( svn_depth_t  depth)

Return a constant string expressing depth as an English word, e.g., "infinity", "immediates", etc.

To allow for extending the svn_log_changed_path2_t structure in future releases, this function should always be used to allocate the structure.
Since
New in 1.6.
svn_log_changed_path2_t* svn_log_changed_path2_dup ( const svn_log_changed_path2_t changed_path,
apr_pool_t *  pool 
)

svn_error_t* svn_mime_type_validate ( const char *  mime_type,
apr_pool_t *  pool 
)

Validate mime_type.

If mime_type does not contain a "/", or ends with non-alphanumeric data, return SVN_ERR_BAD_MIME_TYPE, else return success.

Use pool only to find error allocation.

Goal: to match both "foo/bar" and "foo/bar; charset=blah", without being too strict about it, but to disallow mime types that have quotes, newlines, or other garbage on the end, such as might be unsafe in an HTTP header.

svn_node_kind_t svn_node_kind_from_word ( const char *  word)

Return the appropriate node_kind for word.

word is as returned from svn_node_kind_to_word(). If word does not represent a recognized kind or is NULL, return svn_node_unknown.
