Some error messages related to file handling are using the code path context to define their state. For example, 2PC-related errors are referring to "two-phase status files", or "relation mapping file" is used for catalog-to-filenode mapping, however those prove to be difficult to translate, and are not more helpful than just referring to the path of the file being worked on. So simplify all those error messages by just referring to files with their path used. In some cases, like the manipulation of WAL segments, the context is actually helpful so those are kept. Calls to the system function read() have also been rather inconsistent with their error handling sometimes not reporting the number of bytes read, and some other code paths trying to use an errno which has not been set. The in-core functions are using a more consistent pattern with this patch, which checks for both errno if set or if an inconsistent read is happening. So as to care about pluralization when reading an unexpected number of byte(s), "could not read: read %d of %zu" is used as error message, with %d field being the output result of read() and %zu the expected size. This simplifies the work of translators with less variations of the same message. Author: Michael Paquier Reviewed-by: Álvaro Herrera Discussion: https://postgr.es/m/20180520000522.GB1603@paquier.xyz
PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
