Name file of WAL segment was generated using the API of xlog_internal.h called XlogFileName, based on XLogSegNo and not XLogRecPtr as the previous code assumed. This leaded to backup incorrect, actually too many WAL files in the archive code path because the analysis was based on a name completely fucked up. This commit fixes at the same time an issue in search_next_wal where the function could loop for a too long amount of time, eating much CPU when looking for the next WAL file. Regression tests are passing cleanly with this patch.
pg_rman ======= pg_rman is a backup and recovery manager for PostgreSQL servers able to do incremental, archive and full backup as well as restore a cluster to a state defined by a given recovery target. It is designed to perform periodic backups of an existing PostgreSQL server, combined with WAL archives to provide a way to recover a server in case of failure of server because of a reason or another. Its incremental and archive backup facilities reduces the amount of data necessary to be taken between two consecutive backups. Download -------- The latest version of this software can be found on the project website at https://github.com/michaelpq/pg_rman. Installation ------------ Compiling pg_rman requires a PostgreSQL installation and can be done in two ways: 1. Put pg_rman project directory inside PostgreSQL source tree as contrib/pg_rman, and use "make" to compile or 2. Keep the project directory as-is and use the PGXS development infrastructure provided by a PostgreSQL installation to perform the compilation: "make USE_PGXS=1" In addition, you must have pg_config in $PATH. The current version of pg_rman is compatible with PostgreSQL 9.3 and upper versions. Platforms --------- pg_rman has been tested on Linux and Unix-based platforms. Documentation ------------- All the documentation is written and maintained in pg_rman.txt. Regression tests ---------------- The test suite of pg_rman is available in the code tree and can be launched in a way similar to common PostgreSQL extensions and modules: 1) "make check" or "make installcheck" if the project directory is located in PostgreSQL code tree. 2) "make installcheck" on an already installed server if project directory is kept as-is. License ------- pg_rman can be distributed under the PostgreSQL license. See COPYRIGHT file for more information.
