New Revision: 1807225
URL: http://svn.apache.org/viewvc?rev=1807225&view=rev
Log:
Begin adding support for multiple working copy formats.
Instead of supporting just one format, introduce a current formaat
(the default for new working copies) and a lowest supported format,
and change the way new working copies are created: instead of the
base schema defining the current format, it defines the lowest
supporting format and a series of format updates are performed
to bring it to the current shape.
* subversion/libsvn_wc/wc.h
(SVN_WC__VERSION): Bump to 32.
(SVN_WC__SUPPORTED_VERSION): New; set to 31, the 1.8/1.9 format.
(SVN_WC__COMPRESSED_PRISTINES): NEw; set to 32.
(svn_wc__upgrade_sdb): Add parameter target_format.
(svn_wc__update_schema): New prototype.
* subversion/libsvn_wc/wc_db_private.h
(VERIFY_USABLE_WCROOT): Check the range of supported formats.
* subversion/libsvn_wc/wc_db.c
(init_db): Add parameter wcroot_abspath.
Update the schema to the current format.
(create_db): Update the call to init_db.
(svn_wc__db_bump_format): Update the call to svn_wc__upgrade_sdb.
* subversion/libsvn_wc/wc_db_wcroot.c
(svn_wc__db_pdh_create_wcroot): Allow the range of supported formats.
* subversion/libsvn_wc/lock.c
(open_single): Allow the range of supported formats.
* subversion/libsvn_wc/upgrade.c: Include svn_version.h.
(bump_to_32): New private function.
(svn_wc__version_string_from_format): Add new mappings.
(svn_wc__upgrade_sdb): Extract the schema-update part into ...
(svn_wc__update_schema): ... here.
(svn_wc__update_schema): Implement.
* subversion/libsvn_wc/wc-metadata.sql
(STMT_CREATE_SCHEMA): Set base format to SVN_WC__SUPPORTED_FORMAT.
(STMT_BUMP_TO_32): Update the user_version.
