svn_stream_t - SVN::Stream¶

You can use native perl io handles (including io globs) as svn_stream_t in subversion functions. Returned svn_stream_t are also translated into perl io handles, so you could access them with regular print, read, etc.

Note that some functions take a stream to read from or write to, but do not close the stream while still holding the reference to the io handle. In this case the handle won't be destroyed properly. You should always set up the correct default pool before calling such functions.

svn_pool_t - SVN::Pool¶

The perl bindings significantly simplify the usage of pools, while still being manually adjustable.

For functions requiring a pool as the last argument (which are, almost all of the subversion functions), the pool argument is optional. The default pool is used if it is omitted. When "SVN::Core" is loaded, it creates a new default pool, which is also available from "SVN::Core->gpool".

For callback functions providing a pool to your subroutine, you could also use $pool->default to make it the default pool in the scope.

Methods

new([$parent])

Create a new pool. The pool is a root pool if $parent is not supplied.

new_default([$parent])

Create a new pool. The pool is a root pool if $parent is not supplied. Set the new pool as default pool.

new_default_sub

Create a new subpool of the current default pool, and set the resulting pool as new default pool.

clear

Clear the pool.

DESTROY

Destroy the pool. If the pool was the default pool, restore the previous default pool. This is normally called automatically when the SVN::Pool object is no longer used and destroyed by the perl garbage collector.

svn_error_t - SVN::Error¶

By default the perl bindings handle exceptions for you. The default handler automatically croaks with an appropriate error message. This is likely sufficient for simple scripts, but more complex usage may demand handling of errors.

You can override the default exception handler by changing the $SVN::Error::handler variable. This variable holds a reference to a perl sub that should be called whenever an error is returned by a svn function. This sub will be passed a svn_error_t object. Its return value is ignored.

If you set the $SVN::Error::handler to undef then each call will return an svn_error_t object as its first return in the case of an error, followed by the normal return values. If there is no error then a svn_error_t will not be returned and only the normal return values will be returned. When using this mode you should be careful only to call functions in array context. For example: my ($ci) = $ctx->mkdir('http://svn/foo'); In this case $ci will be an svn_error_t object if an error occurs and a svn_client_commit_info object otherwise. If you leave the parenthesis off around $ci (scalar context) it will be the commit_info object, which in the case of an error will be undef.

If you plan on using explicit exception handling, understanding the exception handling system the C API uses is helpful. You can find information on it in the HACKING file and the API documentation. Looking at the implementation of SVN::Error::croak_on_error and SVN::Error::expanded_message may be helpful as well.

$svn_error_t->apr_err()

APR error value, possibly SVN_ custom error.

$svn_error_t->message()

Details from producer of error.

$svn_error_t->child()

svn_error_t object of the error that's wrapped.

$svn_error_t->pool()

The pool holding this error and any child errors it wraps.

$svn_error_t->file()

Source file where the error originated.

$svn_error_t->line()

Source line where the error originated.

SVN::Error::strerror($apr_status_t)

Returns the english description of the status code.

$svn_error_t->strerror()

Returns the english description of the apr_err status code set on the $svn_error_t. This is short for: SVN::Error::strerror($svn_error_t->apr_err());

SVN::Error::create($apr_err, $child, $message);

Returns a new svn_error_t object with the error status specified in $apr_err, the child as $child, and error message of $message.

SVN::Error::quick_wrap($child, $new_msg); or $child->quick_wrap($new_msg);

A quick n' easy way to create a wrappered exception with your own message before throwing it up the stack.

$child is the svn_error_t object you want to wrap and $new_msg is the new error string you want to set.

SVN::Error::compose($chain, $new_error); or $chain->compose($new_error);

Add new_err to the end of $chain's chain of errors.

The $new_err chain will be copied into $chain's pool and destroyed, so $new_err itself becomes invalid after this function.

SVN::Error::clear($svn_error_t); or $svn_error_t->clear();

Free the memory used by $svn_error_t, as well as all ancestors and descendants of $svn_error_t.

You must call this on every svn_error_t object you get or you will leak memory.

SVN::Error::expanded_message($svn_error_t) or $svn_error_t->expanded_message()

Returns the error message by tracing through the svn_error_t object and its children and concatenating the error messages. This is how the internal exception handlers get their error messages.

SVN::Error::is_error($value)

Returns true if value is of type svn_error. Returns false if value is anything else or undefined. This is useful for seeing if a call has returned an error.

SVN::Error::croak_on_error

Default error handler. It takes an svn_error_t and extracts the error messages from it and croaks with those messages.

It can be used in two ways. The first is detailed above as setting it as the automatic exception handler via setting $SVN::Error::handler.

The second is if you have $SVN::Error::handler set to undef as a wrapper for calls you want to croak on when there is an error, but you don't want to write an explicit error handler. For example:

my $rev = SVN::Error::croak_on_error($ctx->checkout($url,$path,'HEAD',1));

If there is no error then croak_on_error will return the arguments passed to it unchanged.

SVN::Error::confess_on_error

The same as croak_on_error except it will give a more detailed stack backtrace, including internal calls within the implementation of the perl bindings. This is useful when you are doing development work on the bindings themselves.

SVN::Error::ignore_error

This is useful for wrapping around calls which you wish to ignore any potential error. It checks to see if the first parameter is an error and if it is it clears it. It then returns all the other parameters.

Source path of copy, or "undef" if there isn't any previous revision history.

$lcp->copyfrom_rev()

Source revision of copy, or $SVN::Core::INVALID_REVNUM if there is no previous history.

svn_log_changed_path2_t¶

An object to represent a path that changed for a log entry.

$lcp->action()

'A'dd, 'D'elete, 'R'eplace, 'M'odify

$lcp->copyfrom_rev()

Source revision of copy, or $SVN::Core::INVALID_REVNUM if there is no previous history.

$lcp->node_kind()

The type of the node, a $SVN::Node enum; may be $SVN::Node::unknown.

svn_node_kind_t - SVN::Node¶

An enum of the following constants:

$SVN::Node::none, $SVN::Node::file, $SVN::Node::dir, $SVN::Node::unknown.

svn_tristate_t - SVN::Tristate¶

An enum of the following constants:

$SVN::Tristate::true, $SVN::Tristate::false, $SVN::Tristate::unknown

Note that these true/false values have nothing to do with Perl's concept of truth. In fact, each constant would evaluate to true in a boolean context.

svn_depth_t - SVN::Depth¶

An enum of the following constants:

$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 anyhwere in the client-side (Wc/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 files 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.

svn_opt_revision_t¶

A revision, specified in one of "SVN::Core::opt_revision_*" ways.

$rev->kind()
