[PATCH] Get-locations - Finished (more or less)

From: Shlomi Fish <shlomif_at_iglu.org.il>
Date: 2004-04-24 09:20:18 CEST

Hi all!

This time this patch adds the ra_svn/svnserve support. I could really use your
help in reviewing the patch and eliminating potential bugs or things that
weren't done optimally.



Here's the log:
Adds an libsvn_fs layer function to efficiently trace the file historical
(and to a limited extent) location based on its peg revision+URL. Also adds
a callack that implements it to the RA vtable and bindings to it from
libsvn_ra_local, libsvn_ra_dav and libsvn_ra_svn. It also implements
the server-side handlers.

* build.conf
  Compile ra-get-past-location, which is a command line client for this
  functionality to facilitate testing.

* include/svn_fs.h
  Added the declaration of svn_fs_trace_node_locations().

* include/svn_ra.h
  Added the get_locations binding to the bottom of svn_ra_plugin_t.

* libsvn_fs/tree.c
  Added the definition of svn_fs_trace_node_locations with two
  accessory functions.

* libsvn_ra_local/ra_plugin.c
  Added the definition of svn_ra_local__get_locations, a binding
  to the RA vtable callback that handles the operation.
  Added it to the end of the libsvn_ra_local vtable.

* subversion/mod_dav_svn/log.c
  Added the definition of dav_svn__get_locations_report() which handles
  the <S:get-locations> report and response. It has a helper function

* subversion/mod_dav_svn/version.c
  (dav_svn_deliver_report): Added an appropriate case directive to
  handle the get-locations report.

* subversion/mod_dav_svn/dav_svn.h
  Added the declaration of dav_svn__get_locations_report().

* tests/libsvn_ra_local/get-past-location.c
  (new file): a simple standalone command line client that queries for
  the historical URLs at other revisions of a certain URL at a peg revision.

* tests/clients/cmdline/past_loc_tests.py
  (new file): a test suite to test the past revision functionality.

* subversion/libsvn_ra_svn/client.c
  Added the ra_svn_get_locations() handler, and added it to the plugin

* subversion/libsvn_ra_dav/ra_dav.h
  Added the new elements to the enum.
  Added the declaration of svn_ra_dav__get_locations().
  Added the declaration of svn_ra_dav__get_repos_root(). It is being
  made global because I need to use it outside its file.
* subversion/libsvn_ra_dav/session.c
  Made svn_ra_dav__get_repos_root() global instead of static.
  Added svn_ra_dav__get_locations to the ra_dav plugin's vtable.

* subversion/libsvn_ra_dav/fetch.c
  Added the definition of svn_ra_dav__get_locations() and helper functions
  , struct declarations and comments. This function implements the
  get_locations() handler() for ra_dav.

* subversion/svnserve/serve.c
  Added the get_locations() handler for the get-locations command.
  Added it to the main_command[] map.

(also here:

To do:

1. Get feedback on the places marked with "TODO" (in all caps) in the patch.
2. If there's a need, change the behaviour of the ra_dav handler to inform the
upper layer that the server does not support this operation and it should
trace the locations using the log instead. I can use sussman's input on this.
3. Remove the remaining cruft (cmds.gdb file, etc.) from the patch.
4. Forward-port to the latest revision. (currently against 9245).
5. Verify that all the tests run correctly with this patch.
