## Description

The ESourceWebdav extension tracks settings for accessing resources on a remote WebDAV server.

This class exists in libedataserver because we have several WebDAV-based backends. Each of these backends is free to use this class directly or subclass it with additional settings. Subclasses should override the extension name.

The SoupURI is parsed into components and distributed across several other built-in extensions such as ESourceAuthentication and ESourceSecurity.

Access the extension as follows:

    1
    2
    3
    4
    5
    #include <libedataserver/libedataserver.h>

    ESourceWebdav *extension;

    extension = e_source_get_extension (source, E_SOURCE_EXTENSION_WEBDAV_BACKEND);

## Details

### E_SOURCE_EXTENSION_WEBDAV_BACKEND

    #define E_SOURCE_EXTENSION_WEBDAV_BACKEND "WebDAV Backend"

Pass this extension name to `e_source_get_extension()` to access ESourceWebdav. This is also used as a group name in key files.

Since 3.6

### struct ESourceWebdav

    struct ESourceWebdav {
    	ESourceExtension parent;
    	ESourceWebdavPrivate *priv;
    };

Contains only private data that should be read and manipulated using the functions below.

Since 3.6

### struct ESourceWebdavClass

    struct ESourceWebdavClass {
    	ESourceExtensionClass parent_class;
    };

### e_source_webdav_get_avoid_ifmatch ()

    gboolean            e_source_webdav_get_avoid_ifmatch   (ESourceWebdav *extension);

This setting works around a bug in older Apache mod_dav versions.

### Note

We may deprecate this once Apache 2.2.8 or newer becomes sufficiently ubiquitous, or we figure out a way to detect and work around the bug automatically.

`extension` : | an ESourceWebdav
Returns : | whether the WebDAV server is known to exhibit the bug

Since 3.6

### e_source_webdav_set_avoid_ifmatch ()

    void                e_source_webdav_set_avoid_ifmatch   (ESourceWebdav *extension,
                                                             gboolean avoid_ifmatch);

This setting works around a bug in older Apache mod_dav versions.

### Note

We may deprecate this once Apache 2.2.8 or newer becomes sufficiently ubiquitous, or we figure out a way to detect and work around the bug automatically.

Updates the last known display name of a WebDAV resource, which may differ from the "display-name" property of the ESource to which `extension` belongs.

The internal copy of `display_name` is automatically stripped of leading and trailing whitespace. If the resulting string is empty, `NULL` is set instead.

The returned string should be freed with `g_free()` when no longer needed.

`extension` : | an ESourceWebdav
Returns : | the newly-allocated copy of "email-address"

Since 3.6

### e_source_webdav_set_email_address ()

    const gchar *       e_source_webdav_get_resource_query  (ESourceWebdav *extension);

Returns the URI query required to access a resource on a WebDAV server.

This is typically used when the "resource-path" points not to the resource itself but to a web program that generates the resource content on-the-fly. The "resource-query" holds the input values for the program.

`extension` : | an ESourceWebdav
Returns : | the query to access a WebDAV resource

Since 3.6

### e_source_webdav_dup_resource_query ()

    const gchar *       e_source_webdav_get_ssl_trust       (ESourceWebdav *extension);

Returns an SSL certificate trust for the `extension`. The value encodes three parameters, divided by a pipe '|', the first is users preference, can be one of "reject", "accept", "temporary-reject" and "temporary-accept". The second is a host name for which the trust was set. Finally the last is a SHA1 hash of the certificate. This is not meant to be changed by a caller, it is supposed to be manipulated with `e_source_webdav_prepare_ssl_trust_prompt()` and `e_source_webdav_store_ssl_trust_prompt()`.

`extension` : | an ESourceWebdav
Returns : | an SSL certificate trust for the `extension`

Since 3.8

Since 3.8

### e_source_webdav_dup_soup_uri ()

    SoupURI *           e_source_webdav_dup_soup_uri        (ESourceWebdav *extension);

This is a convenience function which returns a newly-allocated SoupURI, its contents assembled from the ESourceAuthentication extension, the ESourceSecurity extension, and `extension` itself. Free the returned SoupURI with `soup_uri_free()`.

`extension` : | an ESourceWebdav
Returns : | a newly-allocated SoupURI. [transfer full]

Since 3.6

### e_source_webdav_set_soup_uri ()

    void                e_source_webdav_set_soup_uri        (ESourceWebdav *extension,
                                                             SoupURI *soup_uri);

This is a convenience function which propagates the components of `uri` to the ESourceAuthentication extension, the ESourceSecurity extension, and `extension` itself. (The "fragment" component of `uri` is ignored.)

`extension` : | an ESourceWebdav
`soup_uri` : | a SoupURI

Since 3.6

### e_source_webdav_prepare_ssl_trust_prompt ()

    ETrustPromptResponse e_source_webdav_prepare_ssl_trust_prompt
                                                            (ESourceWebdav *extension,

Checks `messages`'s certificate against currently stored trust response and either returns what to do immediately, or returns E_TRUST_PROMPT_RESPONSE_UNKNOWN and populates `parameters` with necessary values for a trust prompt.

`extension` : | an ESourceWebdav
`message` : | a SoupMessage with SOUP_STATUS_SSL_FAILED status code
`registry` : | an ESourceRegistry, to use for parent lookups
`parameters` : | an ENamedParameters to be populated
Returns : | What to do with SSL connection, where E_TRUST_PROMPT_RESPONSE_UNKNOWN means 'ask a user, with populated parameters'. Note: The E_TRUST_PROMPT_RESPONSE_REJECT is returned on any errors, like the `message` not being with the SOUP_STATUS_SSL_FAILED status code, no certificate being stored in the `message` and so on.

Since 3.8

### e_source_webdav_prepare_ssl_trust_prompt_with_parent ()

    ETrustPromptResponse e_source_webdav_prepare_ssl_trust_prompt_with_parent
                                                            (ESourceWebdav *extension,

The same as `e_source_webdav_prepare_ssl_trust_prompt()`, only takes `parent_source` directly, instead of an ESourceRegistry.

See `e_source_webdav_prepare_ssl_trust_prompt()` for more details.
