AuthToken gains a regular expression, and IdentLine is changed so as it uses an AuthToken rather than tracking separately the ident user string used for the regex compilation and its generated regex_t. In the case of pg_ident.conf, a set of AuthTokens is built in the pre-parsing phase of the file, and an extra regular expression is compiled when building the list of IdentLines, after checking the sanity of the fields in a pre-parsed entry. The logic in charge of computing and executing regular expressions is now done in a new set of routines called respectively regcomp_auth_token() and regexec_auth_token() that are wrappers around pg_regcomp() and pg_regexec(), working on AuthTokens. While on it, this patch adds a routine able to free an AuthToken, free_auth_token(), to simplify a bit the logic around the requirement of using a specific free routine for computed regular expressions. Note that there are no functional or behavior changes introduced by this commit. The goal of this patch is to ease the use of regular expressions with more items of pg_hba.conf (user list, database list, potentially hostnames) where AuthTokens are used extensively. This will be tackled later in a separate patch. Author: Bertrand Drouvot, Michael Paquier Discussion: https://postgr.es/m/fff0d7c1-8ad4-76a1-9db3-0ab6ec338bf7@amazon.com |

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/.
