* Fix compiler warning on CygwinPeter Eisentraut2020-03-24
| | | | | bf68b79e50e3359accc85c94fa23cc03abb9350a introduced an unused variable compiler warning on Cygwin.
* Unify several ways to tracking backend typePeter Eisentraut2020-03-13
| | | | | | | | | | | | | | Add a new global variable MyBackendType that uses the same BackendType enum that was previously only used by the stats collector. That way several duplicate ways of checking what type a particular process is can be simplified. Since it's no longer just for stats, move to miscinit.c and rename existing functions to match the expanded purpose.

* Refactor ps_status.c APIPeter Eisentraut2020-03-11
| | | | | | | | | | | | | | | | | | | | | | The init_ps_display() arguments were mostly lies by now, so to match typical usage, just use one argument and let the caller assemble it from multiple sources if necessary. The only user of the additional arguments is BackendInitialize(), which was already doing string assembly on the caller side anyway. Remove the second argument of set_ps_display() ("force") and just handle that in init_ps_display() internally. BackendInitialize() also used to set the initial status as "authentication", but that was very far from where authentication actually happened. So now it's set to "initializing" and then "authentication" just before the actual call to ClientAuthentication().

* Make the order of the header file includes consistent in backend modules.Amit Kapila2019-11-12
| | | | | | | | | | | Similar to commits 7e735035f2 and dddf4cdc33, this commit makes the order of header file inclusion consistent for backend modules. In the passing, removed a couple of duplicate inclusions.

* Phase 2 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change pg_bsd_indent to follow upstream rules for placement of comments to the right of code, and remove pgindent hack that caused comments following #endif to not obey the general rule. Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using the published version of pg_bsd_indent, but a hacked-up version that tried to minimize the amount of movement of comments to the right of code. The situation of interest is where such a comment has to be moved to the right of its default placement at column 33 because there's code there. BSD indent has always moved right in units of tab stops in such cases --- but in the previous incarnation, indent was working in 8-space tab stops, while now it knows we use 4-space tabs. So the net result is that in about half the cases, such comments are placed one tab stop left of before. This is better all around: it leaves more room on the line for comment text, and it means that in such cases the comment uniformly starts at the next 4-space tab stop after the code, rather than sometimes one and sometimes two tabs after. Also, ensure that comments following #endif are indented the same as comments following other preprocessor commands such as #else. That inconsistency turns out to have been self-inflicted damage from a poorly-thought-through post-indent "fixup" in pgindent. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Refer to OS X as "macOS", except for the port name which is still "darwin".Tom Lane2016-09-25
| | | | | | | | | | | | | | | | | | 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?
* Fix a bunch of places that called malloc and friends with no NULL check.Tom Lane2016-08-30
| | | | | | | | | | | | | | | Where possible, use palloc or pg_malloc instead; otherwise, insert explicit NULL checks. Generally speaking, these are places where an actual OOM is quite unlikely, either because they're in client programs that don't allocate all that much, or they're very early in process startup so that we'd likely have had a fork() failure instead. Hence, no back-patch, even though this is nominally a bug fix. Michael Paquier, with some adjustments by me Discussion: <CAB7nPqRu07Ot6iht9i9KRfYLpDaF2ZuUv5y_+72uP23ZAGysRg@mail.gmail.com>

* Add cluster_name GUC which is included in process titles if set.Andres Freund2014-06-29
| | | | | | | | | | | | | | | | | | When running several postgres clusters on one OS instance it's often inconveniently hard to identify which "postgres" process belongs to which postgres instance. Add the cluster_name GUC, whose value will be included as part of the process titles if set. With that processes can more easily identified using tools like 'ps'. To avoid problems with encoding mismatches between postgresql.conf, consoles, and individual databases replace non-ASCII chars in the name with question marks. The length is limited to NAMEDATALEN to make it less likely to truncate important information at the end of the status. Thomas Munro, with some adjustments by me and review by a host of people.
* Remove Alpha and Tru64 support.Andres Freund2014-06-28
| | | | | | | | | | | | | Support for running postgres on Alpha hasn't been tested for a long while. Due to Alpha's uniquely lax cache coherency model it's a hard to develop for platform (especially blindly!) and thought to be unlikely to currently work correctly. As Alpha is the only supported architecture for Tru64 drop support for it as well. Tru64's support has ended 2012 and it has been in maintenance-only mode for much longer. Also remove stray references to __ksr__ and ultrix defines.

* Pad the ps_status display with nulls, not blanks, on Darwin.Tom Lane2010-09-04

* Change ps_status.c to explicitly track the current logical length of ps_buffer.Tom Lane2010-05-27
| | | | | | | | | | | This saves cycles in get_ps_display() on many popular platforms, and more importantly ensures that get_ps_display() will correctly return an empty string if init_ps_display() hasn't been called yet. Per trouble report from Ray Stell, in which log_line_prefix %i produced junk early in backend startup. Back-patch to 8.0. 7.4 doesn't have %i and its version of get_ps_display() makes no pretense of avoiding pad junk anyhow.

* Repair an error introduced by log_line_prefix patch: it is not acceptableTom Lane2005-11-05
| | | | | | | | | | | to assume that the string pointer passed to set_ps_display is good forever. There's no need to anyway since ps_status.c itself saves the string, and we already had an API (get_ps_display) to return it. I believe this explains Jim Nasby's report of intermittent crashes in elog.c when %i format code is in use in log_line_prefix. While at it, repair a previously unnoticed problem: on some platforms such as Darwin, the string returned by get_ps_display was blank-padded to the maximum length, meaning that lock.c's attempt to append " waiting" to it never worked.

This patch adds this functionality, in a bit of a crufty way. It creates a kernel Event object with the name of what would be in the title. This can be viewed using for example Process Explorer. It's been very handy for me during both debugging and using. I haven't figured a better way, but perhaps someone has one that's less crufty? If not, here is at least a working patch :-) Magnus Hagander
