Core PBX routines.
Definition in file pbx.c.
#define EXT_DATA_SIZE 8192 |
The speed of extension handling will likely be among the most importantaspects of this PBX. The switching scheme as it exists right now isn't terribly bad (it's O(N+M), where N is the # of extensions and M is the avg # of priorities, but a constant search time here would be great ;-)
A new algorithm to do searching based on a 'compiled' pattern tree is introduced here, and shows a fairly flat (constant) search time, even for over 10000 patterns.
Also, using a hash table for context/priority name lookup can help prevent the find_extension routines from absorbing exponential cpu cycles as the number of contexts/priorities grow. I've previously tested find_extension with red-black trees, which have O(log2(n)) speed. Right now, I'm using hash tables, which do searches (ideally) in O(1) time. While these techniques do not yield much speed in small dialplans, they are worth the trouble in large dialplans.

Main interface to add extensions to the list for out context.
Add an extension to an extension context, this time with an ast_context *.
We sort extensions in order of matching preference, so that we can stop the search as soon as we find a suitable match. This ordering also takes care of wildcards such as '.' (meaning "one or more of any character") and '!' (which is 'earlymatch', meaning "zero or more of any character" but also impacts the return value from CANMATCH and EARLYMATCH.
The extension match rules defined in the devmeeting 2006.05.05 are quite simple: WE SELECT THE LONGEST MATCH. In detail, "longest" means the number of matched characters in the extension. In case of ties (e.g. _XXX and 333) in the length of a pattern, we give priority to entries with the smallest cardinality (e.g, [5-9] comes before [2-8] before the former has only 5 elements, while the latter has 7, etc. In case of same cardinality, the first element in the range counts. If we still have a tie, any final '!' will make this as a possibly less specific pattern.
EBUSY - can't lock EEXIST - extension with the same priority exist and no replace is set

helper functions to sort extension patterns in the desired way, so that more specific patterns appear first.
The function compares individual characters (or sets of), returning an int where bits 0-7 are the ASCII code of the first char in the set, bits 8-15 are the number of characters in the set, and bits 16-20 are for special cases. This way more specific patterns (smaller character sets) appear first. Wildcards have a special value, so that we can directly compare them to sets by subtracting the two values. In particular: 0x001xx one character, character set starting with xx 0x0yyxx yy characters, character set starting with xx 0x18000 '.' (one or more of anything) 0x28000 '!' (zero or more of anything) 0x30000 NUL (end of string) 0x40000 error in set. The pointer to the string is advanced according to needs. NOTES:

The return value depends on the action:
E_MATCH, E_CANMATCH, E_MATCHMORE require a real match, and return 0 on failure, -1 on match; E_FINDLABEL maps the label to a priority, and returns the priority on success, ... XXX E_SPAWN, spawn an application,
0 | on success. |
-1 | on failure. |

int pbx_set_autofallthrough | ( | int | newval | ) |
Set "autofallthrough" flag, if newval is <0, does not actually set. If set to 1, sets to auto fall through. If newval set to 0, sets to no auto fall through (reads extension instead). Returns previous value.
int pbx_set_extenpatternmatchnew | ( | int | newval | ) |
Set "extenpatternmatchnew" flag, if newval is <0, does not actually set. If set to 1, sets to use the new Trie-based pattern matcher. If newval set to 0, sets to use the old linear-search algorithm. Returns previous value.
void pbx_set_overrideswitch | ( | const char * | newval | ) |
Set "overrideswitch" field. If set and of nonzero length, all contexts will be tried directly through the named switch prior to any other matching within that context.
