Magnus Hagander	76129e7f14	Include more status information in walsender results ... Add the current xlog insert location to the response of IDENTIFY_SYSTEM, and adds result sets containing start and stop location of backups to BASE_BACKUP responses.	15 years ago
Heikki Linnakangas	997b48ed96	Support multiple concurrent pg_basebackup backups. ... With this patch, pg_basebackup doesn't write a backup_label file in the data directory, so it doesn't interfere with a pg_start/stop_backup() based backup anymore. backup_label is still included in the backup, but it is injected directly into the tar stream.

Magnus Hagander	507069de6d	Add option to include WAL in base backup ... When included, this makes the base backup a complete working "clone" of the initial database, ready to have a postmaster started against it without the need to set up any log archiving or similar.

Magnus Hagander	966d4f52c2	Typo fix for MemSet size. ... Fujii Masao	15 years ago
Magnus Hagander	e5487f65fd	Make walsender options order-independent ... While doing this, also move base backup options into a struct instead of increasing the number of parameters to multiple functions for each new option.	15 years ago
Magnus Hagander	048d148fe6	Add pg_basebackup tool for streaming base backups ... This tool makes it possible to do the pg_start_backup/ copy files/pg_stop_backup step in a single command. There are still some steps to be done before this is a complete backup solution, such as the ability to stream the required WAL logs, but it's still usable, and could do with some buildfarm coverage. In passing, make the checkpoint request optionally fast instead of hardcoding it. Magnus Hagander, reviewed by Fujii Masao and Dimitri Fontaine	15 years ago
Magnus Hagander	3866ff6149	Enumerate available tablespaces after starting the backup ... This closes a race condition where if a tablespace was created after the enumeration happened but before the do_pg_start_backup() was called, the backup would be incomplete. Now that it's done while we are in backup mode, WAL replay will recreate it during restore. Noted by Heikki.	15 years ago
Magnus Hagander	fcd810c69a	Use a lexer and grammar for parsing walsender commands ... Makes it easier to parse mainly the BASE_BACKUP command with it's options, and avoids having to manually deal with quoted identifiers in the label (previously broken), and makes it easier to add new commands and options in the future. In passing, refactor the case statement in the walsender to put each command in it's own function.	15 years ago
Magnus Hagander	688423d004	Exit from base backups when shutdown is requested ... When the exit waits until the whole backup completes, it may take a very long time. In passing, add back an error check in the main loop so we detect clients that disconnect much earlier if the backup is large.	15 years ago
Magnus Hagander	4c8e20f815	Track walsender state in shared memory and expose in pg_stat_replication	15 years ago
Magnus Hagander	47a5f3e9da	Add missing function prototype, for consistency	15 years ago
Tom Lane	e6dce4e439	Adjust basebackup.c to suppress compiler warnings. ... Some versions of gcc complain about "variable `tablespaces' might be clobbered by `longjmp' or `vfork'" with the original coding. Fix by moving the PG_TRY block into a separate subroutine.	15 years ago
Magnus Hagander	2e36343f82	Set process title to indicate base backup is running	15 years ago
Heikki Linnakangas	dc1305ce5f	Leave temporary files out of streaming base backups.	15 years ago
Magnus Hagander	0eb59c4591	Backend support for streaming base backups ... Add BASE_BACKUP command to walsender, allowing it to stream a base backup to the client (in tar format). The syntax is still far from ideal, that will be fixed in the switch to use a proper grammar for walsender. No client included yet, will come as a separate commit.
