Detailed Description

commit action.

This is a bit hairy in that the order in which we process files (sorted by inode, not in the directory structure) is not allowed for a subversion editor.

We have to read the complete tree, get the changes and store what we want to do, and send these changes in a second run.

Committing two revisions at once

Handling identical files; using hardlinks; creating two revisions on commit.

There are some use-cases where we'd like to store the data only a single time in the repository, so that multiple files are seen as identical:

typedef svn_error_t*(* change_any_prop_t)(void *baton, const char *name, const svn_string_t *value, apr_pool_t *pool)

Function Documentation

svn_error_t* ci___base_dirs ( char *  current_missing,
const svn_delta_editor_t *  editor,
struct estat root,
void *  dir_baton 
)

Creates base directories from missing_path_utf8, if necessary, and calls ci__directory().

current_missing points into missing_path_utf8_len, to the current path spec; editor, root and dir_baton are as in ci__directory().

As the number of directories created this way is normally 0, and for typical non-zero use I'd believe about 3 or 4 levels (maximum), we don't use an extra recursion pool here.

int ci___send_user_props ( void *  baton,
struct estat sts,
change_any_prop_t  function,
int  store_encoder,
apr_pool_t *  pool 
)

Send the user-defined properties.

The property table is left cleaned up, ie. any deletions that were ordered by the user have been done -- no properties with prp__prop_will_be_removed() will be here.

If store_encoder is set, sts->decoder gets set from the value of the commit-pipe.

auto-props from groupings are sent, too.

Here is the caller graph for this function:

svn_error_t* ci___set_props ( void *  baton,

Send the meta-data-properties for baton.

We hope that group/user names are ASCII; the names of "our" properties are known, and contain no characters above \x80.

We get the function passed, because subversion has different property setters for files and directories.

If props is not NULL, we return the properties' handle.

Removes the flags saying that this entry was copied, recursively.

Does stop on new copy-bases.

Is needed because a simple "cp -a" wouldn't even go down into the child-entries - there's nothing to do there!

Callback for successfull commits.

This is the only place that gets the new revision number told.

svn_ra.h does not tell whether these strings are really UTF8. I think they must be ASCII, except if someone uses non-ASCII-user names ... which nobody does.

The main commit function.

It does as much setup as possible before traversing the tree - to find errors (no network, etc.) as soon as possible.

The message file gets opened here to verify its existence, and to get a handle to it. If we're doing chdir()s later we don't mind; the open handle let's us read when we need it. And the contents are cached only as long as necessary.
