We weren't terribly consistent about whether to call Apple's OS "OS X"
or "Mac OS X", and the former is probably confusing to people who aren't
Apple users. Now that Apple has rebranded it "macOS", follow their lead
to establish a consistent naming pattern. Also, avoid the use of the
ancient project name "Darwin", except as the port code name which does not
seem desirable to change. (In short, this patch touches documentation and
comments, but no actual code.)
I didn't touch contrib/start-scripts/osx/, either. I suspect those are
obsolete and due for a rewrite, anyway.
I dithered about whether to apply this edit to old release notes, but
those were responsible for quite a lot of the inconsistencies, so I ended
up changing them too. Anyway, Apple's being ahistorical about this,
so why shouldn't we be?
Somebody added pg_replication_origin, pg_replication_origin_status and
pg_replication_slots to catalogs.sgml without a whole lot of concern for
either alphabetical order or the difference between a table and a view.
Clean up the mess.
Back-patch to 9.5, not so much because this is critical as because if
I don't it will result in a cross-branch divergence in release-9.5.sgml,
which would be a maintenance hazard.
Also fill in the previously empty "major enhancements" list. YMMV as to
which items should make the cut, but it's past time we had something more
than a placeholder here.
(I meant to get this done before beta2 was wrapped, but got distracted by
PDF build problems. Better late than never.)
Per discussion, the original name was a bit misleading, and
PQsslAttributeNames() seems more apropos. It's not quite too late to
change this in 9.5, so let's change it while we can.
Also, make sure that the pointer array is const, not only the pointed-to
strings.
Minor documentation wordsmithing while at it.
Lars Kanis, slight adjustments by me
Fix some brain fade in commit a2dabf0e1dda93c8: erroneous variable names
in docs, rearrangements that made sentences less clear not more so,
undocumented and poorly-chosen-anyway API behaviors of subroutines,
bad grammar in error messages, copy-and-paste faults.
Albe Laurenz and Tom Lane
Although commit 79af9a1d2 was initially applied to HEAD only, we later
back-patched the change into all branches (commits 6bbf75192 et al).
So it's not a new behavior in 9.5 and should not be release-noted here.
1) Add sgml comments referencing commits. This is useful to search for
missing items etc.
The comments containing the commit notes are an excerpt from:
git log --date=short \
--pretty='format:%cd [%h] %<(8,trunc)%cN: %<(48,trunc)%s%n%n%w(,4,4)%b%n' \
$(git merge-base origin/master upstream/REL9_4_STABLE)..origin/master
2) Improve a handful of existing notes
3) Add missing entries about a couple features.
4) Add a bunch of straight-forward FIXMEs
Minor corrections and clarifications. Notably, for stuff that got moved
out of contrib, make sure it's documented somewhere other than "Additional
Modules".
I'm sure these need more work, but that's all I have time for today.
As first committed, this view reported on the file contents as they were
at the last SIGHUP event. That's not as useful as reporting on the current
contents, and what's more, it didn't work right on Windows unless the
current session had serviced at least one SIGHUP. Therefore, arrange to
re-read the files when pg_show_all_settings() is called. This requires
only minor refactoring so that we can pass changeVal = false to
set_config_option() so that it won't actually apply any changes locally.
In addition, add error reporting so that errors that would prevent the
configuration files from being loaded, or would prevent individual settings
from being applied, are visible directly in the view. This makes the view
usable for pre-testing whether edits made in the config files will have the
desired effect, before one actually issues a SIGHUP.
I also added an "applied" column so that it's easy to identify entries that
are superseded by later entries; this was the main use-case for the original
design, but it seemed unnecessarily hard to use for that.
Also fix a 9.4.1 regression that allowed multiple entries for a
PGC_POSTMASTER variable to cause bogus complaints in the postmaster log.
(The issue here was that commit bf007a27ac unintentionally reverted
3e3f65973a, which suppressed any duplicate entries within
ParseConfigFp. However, since the original coding of the pg_file_settings
view depended on such suppression *not* happening, we couldn't have fixed
this issue now without first doing something with pg_file_settings.
Now we suppress duplicates by marking them "ignored" within
ProcessConfigFileInternal, which doesn't hide them in the view.)
Lesser changes include:
Drive the view directly off the ConfigVariable list, instead of making a
basically-equivalent second copy of the data. There's no longer any need
to hang onto the data permanently, anyway.
Convert show_all_file_settings() to do its work in one call and return a
tuplestore; this avoids risks associated with assuming that the GUC state
will hold still over the course of query execution. (I think there were
probably latent bugs here, though you might need something like a cursor
on the view to expose them.)
Arrange to run SIGHUP processing in a short-lived memory context, to
forestall process-lifespan memory leaks. (There is one known leak in this
code, in ProcessConfigDirectory; it seems minor enough to not be worth
back-patching a specific fix for.)
Remove mistaken assignment to ConfigFileLineno that caused line counting
after an include_dir directive to be completely wrong.
Add missed failure check in AlterSystemSetConfigFile(). We don't really
expect ParseConfigFp() to fail, but that's not an excuse for not checking.
