2022-10-14Replace the sorted array of GUC variables with a hash table.Tom Lane
This gets rid of bsearch() in favor of hashed lookup. The main advantage is that it becomes far cheaper to add new GUCs, since we needn't re-sort the pointer array. Adding N new GUCs had been O(N^2 log N), but now it's closer to O(N). We need to sort only in SHOW ALL and equivalent functions, which are hopefully not performance-critical to anybody. Also, merge GetNumConfigOptions() into get_guc_variables(), because in a world where the set of GUCs isn't fairly static you really want to consider those two results as tied together not independent.

2018-07-11Rethink how to get float.h in old Windows API for isnan/isinfAlvaro Herrera
We include <float.h> in every place that needs isnan(), because MSVC used to require it. However, since MSVC 2013 that's no longer necessary (cf. commit cec8394b5ccd), so we can retire the inclusion to a version-specific stanza in win32_port.h, where it doesn't need to pollute random .c files. The header is of course still needed in a few places for other reasons. I (Álvaro) removed float.h from a few more files than in Emre's original patch. This doesn't break the build in my system, but we'll see what the buildfarm has to say about it all.

2017-06-21Phase 3 of pgindent updates.Tom Lane
Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. 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.

2015-08-15Don't use 'bool' as a struct member name in help_config.c.Andres Freund
Doing so doesn't work if bool is a macro rather than a typedef. Although c.h spends some effort to support configurations where bool is a preexisting macro, help_config.c has existed this way since 2003 (b700a6), and there have not been any reports of problems. Backpatch anyway since this is as riskless as it gets. Discussion: [email protected] Backpatch: 9.0-master

2012-06-25Unify calling conventions for postgres/postmaster sub-main functionsPeter Eisentraut
There was a wild mix of calling conventions: Some were declared to return void and didn't return, some returned an int exit code, some claimed to return an exit code, which the callers checked, but actually never returned, and so on. Now all of these functions are declared to return void and decorated with attribute noreturn and don't return. That's easiest, and most code already worked that way.

2004-06-02Fix breakage from GUC-extension-variables patch.Tom Lane
2004-05-26The patch adresses the TODO list item "Allow external interfaces toBruce Momjian
extend the GUC variable set". Plugin modules like the pl<lang> modules needs a way to declare configuration parameters. The postmaster has no knowledge of such modules when it reads the postgresql.conf file. Rather than allowing totally unknown configuration parameters, the concept of a variable "class" is introduced. Variables that belongs to a declared classes will create a placeholder value of string type and will not generate an error. When a module is loaded, it will declare variables for such a class and make those variables "consume" any placeholders that has been defined. Finally, the module will generate warnings for unrecognized placeholders defined for its class. More detail: The design is outlined after the suggestions made by Tom Lane and Joe Conway in this thread: http://archives.postgresql.org/pgsql-hackers/2004-02/msg00229.php A new string variable 'custom_variable_classes' is introduced. This variable is a comma separated string of identifiers. Each identifier denots a 'class' that will allow its members to be added without error. This variable must be defined in postmaster.conf. The lexer (guc_file.l) is changed so that it can accept a qualified name in the form <ID>.<ID> as the name of a variable. I also changed so that the 'custom_variable_classes', if found, is added first of all variables in order to remove the order of declaration issue. The guc_variables table is made more dynamic. It is originally created with 20% slack and can grow dynamically. A capacity is introduced to avoid resizing every time a new variable is added. guc_variables and num_guc_variables becomes static (hidden). The GucInfoMain now uses the new function get_guc_variables() and GetNumConfigOptions instead or using the guc_variables directly. The find_option() function, when passed a missing name, will check if the name is qualified. If the name is qualified and if the qualifier denotes a class included in the 'custom_variable_classes', a placeholder variable will be created. Such a placeholder will not participate in a list operation but will otherwise function as a normal string variable. Define<type>GucVariable() functions will be added, one for each variable type. They are inteded to be used by add-on modules like the pl<lang> mappings. Example: extern void DefineCustomBoolVariable( const char* name, const char* short_desc, const char* long_desc, bool* valueAddr, GucContext context, GucBoolAssignHook assign_hook, GucShowHook show_hook); (I created typedefs for the assign-hook and show-hook functions). A call to these functions will define a new GUC-variable. If a placeholder exists it will be replaced but it's value will be used in place of the default value. The valueAddr is assumed ot point at a default value when the define function is called. The only constraint that is imposed on a Custom variable is that its name is qualified. Finally, a function: void EmittWarningsOnPlacholders(const char* className) was added. This function should be called when a module has completed its variable definitions. At that time, no placeholders should remain for the class that the module uses. If they do, elog(INFO, ...) messages will be issued to inform the user that unrecognized variables are present.
