#/packages/acs-lang/tcl/lang-catalog-procs.tcl ad_library { <p> Routines for importing/exporting messages from/to XML message catalog files. Every OpenACS package has one message catalog file for each locale (language and region) that its UI supports. Importing of messages means reading the messages from XML catalog files and storing them in the database. Exporting of messages refers to the opposite process. The key procedures in this library are: </p> <p> <ul> <li>lang::catalog::import - Import all catalog files on the system into the database. Can be restricted to only import from one package and only certain locales.</li> <li>lang::catalog::import_from_file - Import from a single catalog file</li> <li>lang::catalog::export - Export all messages in the database to catalog files. Can be restricted to only export from one package and only certain locales.</li> <li>lang::catalog::export_to_file - Export messages to a single file</li> </ul> </p> @creation-date 10 September 2000 @author Jeff Davis @author Peter Marklund (peter@collaboraid.biz) @author Lars Pind (lars@collaboraid.biz) @cvs-id $Id: lang-catalog-procs.tcl,v 1.63 2024/10/08 13:35:13 antoniop Exp $ } namespace eval lang::catalog {} ################## # # Helper procs # ################## ad_proc -private lang::catalog::default_charset_if_unsupported { charset } { Will return the system default charset and issue a warning in the log file if the given charset is not supported by tcl.

The first such sync point is the initial import of a message. After that, any export of messages to the filesystem will be a sync point. Also, after an upgrade, a large number of the resulting messages in the db will be identical to those in the file (the file messages take precedence on conflict) and those messages will also be sync points.

We will distinguish all the different permutations of each of the three messages existing or not, and all permutations of the messages being different from each other. We don't distinguish how two messages are different, only whether they are different or not.

Differ (conflicting change): upgrade_action=delete, conflict_p=t 7. No difference (no conflicting change): upgrade_action=delete, conflict_p=f - File and db message (message added in both db and file): 8.
