* Teach pg_upgrade to handle in-place tablespaces.Nathan Bossart6 days
| | | | | | | | | | | | | | | | | | | | Presently, pg_upgrade assumes that all non-default tablespaces don't move to different directories during upgrade. Unfortunately, this isn't true for in-place tablespaces, which move to the new cluster's pg_tblspc directory. This commit teaches pg_upgrade to handle in-place tablespaces by retrieving the tablespace directories for both the old and new clusters. In turn, we can relax the prohibition on non-default tablespaces for same-version upgrades, i.e., if all non-default tablespaces are in-place, pg_upgrade may proceed. This change is primarily intended to enable additional pg_upgrade testing with non-default tablespaces, as is done in 006_transfer_modes.pl.

* Use printf's %m format instead of strerror(errno) in more placesMichael Paquier2024-03-12
| | | | | | | | | | | | | | | | | Most callers of strerror() are removed from the backend code. The remaining callers require special handling with a saved errno from a previous system call. The frontend code still needs strerror() where error states need to be handled outside of fprintf. Note that pg_regress is not changed to use %m as the TAP output may clobber errno, since those functions call fprintf() and friends before evaluating the format string. Support for %m in src/port/snprintf.c has been added in d6c55de1f99a, hence all the stable branches currently supported include it.

* Remove trailing newlines in pg_upgrade's message strings.Tom Lane2022-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg_upgrade does not use common/logging.c, which is unfortunate but changing it to do so seems like more work than is justified. However, we really need to make it work more like common/logging.c in one respect: the latter expects supplied message strings to not end with a newline, instead adding one internally. As it stands, pg_upgrade's logging facilities expect a caller-supplied newline in some cases and not others, which is already an invitation to bugs, but the inconsistency with our other frontend code makes it worse. There are already several places with missing or extra newlines, and it's inevitable that there won't be more if we let this stand. Hence, run around and get rid of all trailing newlines in message strings, and add an Assert that there's not one, similar to the existing Assert in common/logging.c. Adjust the logging functions to supply a newline at the right places. (Some of these strings also have a *leading* newline, which would be a good thing to get rid of too; but this patch doesn't attempt that.) There are some consequent minor changes in output. The ones that aren't outright bug fixes are generally removal of extra blank lines that the original coding intentionally inserted. It didn't seem worth being bug-compatible with that.

* Remove redundant null pointer checks before pg_free()Peter Eisentraut2022-07-03
| | | | | | | | | | These are especially useless because the whole point of pg_free() was to do that very check before calling free(). pg_free() could be removed altogether, but I'm keeping it here to keep the API consistent.

* Factor out system call names from error messagesPeter Eisentraut2021-04-23
| | | | | | | | | | Instead, put them in via a format placeholder. This reduces the number of distinct translatable messages and also reduces the chances of typos during translation. We already did this for the system call arguments in a number of cases, so this is just the same thing taken a bit further.

* Make error handling in parallel pg_upgrade less bogus.Tom Lane2018-12-16
| | | | | | | | | | | | reap_child() basically ignored the possibility of either an error in waitpid() itself or a child process failure on signal. We don't really need to do more than report and crash hard, but proceeding as though nothing is wrong is definitely Not Acceptable. The error report for nonzero child exit status was pretty off-point, as well. Noted while fooling around with child-process failure detection logic elsewhere. It's been like this a long time, so back-patch to all supported branches.
* pg_upgrade: prevent check on live cluster from generating errorBruce Momjian2018-01-08
| | | | | | | | | | | Previously an inaccurate but harmless error was generated when running --check on a live server before reporting the servers as compatible. The fix is to split error reporting and exit control in the exec_prog() API. Reported-by: Daniel Westermann Backpatch-through: 10

* Remove useless duplicate inclusions of system header files.Tom Lane2017-02-25
| | | | | | | | | | | | | | | | c.h #includes a number of core libc header files, such as <stdio.h>. There's no point in re-including these after having read postgres.h, postgres_fe.h, or c.h; so remove code that did so. While at it, also fix some places that were ignoring our standard pattern of "include postgres[_fe].h, then system header files, then other Postgres header files". While there's not any great magic in doing it that way rather than system headers last, it's silly to have just a few files deviating from the general pattern. (But I didn't attempt to enforce this globally, only in files I was touching anyway.) I'd be the first to say that this is mostly compulsive neatnik-ism, but over time it might save enough compile cycles to be useful.
