More about ADTs
by Peta, jo det �r jag ＠ Pike developers forum 04 May '04

04 May '04

I've made som changes and here is a new suggestion for a common interface of the new ADTs. Common API for new ADTs in Pike 1. Introduction This document describes a common platform for new ADTs in pike to stand on. The purpose of the platform is to make the new ADTs as flexible as possible and possible to use together with generic algorithms. The base of the platform is the Collection concept, being the base concepts of all the ADTs, and the Iterator concept making it possible to iterate over collections without knowing the underlying structure. Besides the two base concepts this document also describes a few sub-concepts that are related to the two base concepts according to the two figures below. Figur 1 Collection concepts Collection |-----------> Ordered Collection | | | |--------> Sequence | |--------> Ordered Set <------| | |--------> Ordered Map <--| | |----> Map --------------------------------------| | |----> Set ------------------------------------------| Figur 2 Interface concepts Iterator -------> Ordered Iterator 2. Collection concepts 2.1. Collection Collection is the base concept of all the ADTs. The reason it is called collection is that all the ADTs in the library is in some way a collection of items. To implement a collection the following methods must be implemented iterator _get_iterator() Return an iterator for this ADT positioned at the first item in the ADT. int _sizeof() Return the current size of the ADT. Return -1 if the size could not be decided or is truly unlimited. array _values() Return an array with the values in the ADT. int _has_value(mixed value) Returns 1 if value is in the value domain of collection, or 0 (zero) if not found int _equal(mixed coll) Decide if the collection coll and this collection contains the same elements, an if it is important, in the same order. string _sprintf(int conversion_type, mapping(string:int)|void params) Present the collection in a human readable way. For more information see _sprintf in the pike manual. int is_empty() Return 0 if the ADT do has elements. int max_size() Return the maximal size of the ADT if there is any, otherwise -1. void clear() Clear the ADT. iterator first() Return an iterator for this ADT positioned at the first item in the ADT, same as _get_iterator(). iterator last() Return an iterator for this ADT positioned at the last item in the ADT. 2.2. Set Set is a collection containing any number of items but only one of each item. It is a sub-concept of Collection and must thereby besides implementing the methods below also implements the methods in Collections. int '[](mixed item) Return 1 if the item could be found in the set, 0 if it couldn't int '[]=(mixed item, int exist) Add the item to the set if exist is true remove the item if exist is false. iterator get_iterator(mixed item) Get an iterator for this ADT positioned at the item or null if the item could not be found int insert(mixed item) Add the item to the set if it isn't a part of the set. Return true if the item was added, else false. mixed delete(mixed item) Remove the item from the set. If the item was removed it will be returned otherwise a 0 zero_type is returned. multiset cast("multiset") The set should at least be able to cast to a multiset, additional castings are optional. 2.3. Map A map is a data structure that allows you to associate a key with one or more values and then quickly retrieve those values using the key. To implement a Map the ADT must have all the methods in this concept and in the Collection concept. mixed '[](mixed key) Return the item associated with the key if it could be found, 0 if it couldn't mixed '[]=(mixed key, mixed item) If there is an item with the key key then the associated item will be overwritten with the supplied item. If there is no key in the map a new key-item pair will be added. iterator get_iterator(mixed key) Get an iterator for this ADT positioned at the key or null if the key could not be found. mixed insert(mixed key, mixed item) If the key doesn't exist or duplicates are allowed, associate the value with the key and return 0, otherwise don't modify the map and return the current value associated with the key. mixed delete(mixed key) Remove the pair with the key key. Return the keys value if it was removed, if the key could not be removed return zero_type. mapping cast("mapping") The map should at leas be able to cast to a mapping, additional castings are optional. 2.4. OrderedCollection An OrderedCollection is a collection that has indices that could be used to find the values and the indices are strictly ordered is some way. Any type could be used as an index if it satisfies a few rules. See Index for more information. There is also nothing that prevents the use of the values as indices as long as the value satisfies the rules for an Index. int _has_index(int index) Returns 1 if index is in the index domain of collection, or 0 (zero) if not found array _indices() Return an array with the indices of the collection. 2.5. Sequence A sequence is a sub-concept of an Ordered Collection. It is a linear collection that allows index-based access and automatically expands to accommodate new elements. A vector is a good example. mixed '[](int ind) Return the item at index ind in the sequence. Throw an error if ind is out of range. mixed '[]=(int ind, mixed item) Set the index ind to be item. Throw an error if ind is out of range int _search(mixed item, void|int start) Return the index of the first item in the sequence with the index start or higher that match the item item. -1 if no object was found. Throw an error if start is out of range. void insert(index ind, mixed item) Insert an item in the sequence at the index ind. The size of the sequence is increased by one and the items at index and above have their indices increases by one. Throw an error if ind is out of range. int(0..1) delete(mixed item) Remove the first value that are equal to item from the sequence. Return 1 if a item was removed, otherwise 0; void add(mixed item) Add the object item as fast as possible to the sequence. int delete_at(int ind) Remove the item at the index ind. The size of the sequence is decreased by one and the items above ind have their indices decreases by one. Return 0 if the removal failed. Throw an error if ind is out of range. iterator get_iterator(int ind) Get an iterator for this ADT positioned at the index ind. Throw an error if ind is out of range. array cast("array") The sequence should at least be able to cast to an array, additional castings are optional. 2.6. OrderedMap An OrderedMap is a map where the keys are orderable and the iterator belonging to an OrderedMap will traverse the values in that order. 2.7. OrderedSet An OrderedSet is a set were the values are orderable and the iterator belonging to an OrderedSet will traverse the values in that order. 3. Iterator concepts 3.1. Iterator The iterator concept does not differ much from the present day iterator. Only a few new methods are added to make it possible to step backwards and compare iterators. int(01) '!() Should return 0 (zero) when not at end of collection, and 1 at end of collection void '+=(int n) Should advance the specified number of steps iterator '-=(int n) Move the iterator n steps backwards int '==(iterator iter) Return true if the two iterators is pointing to the same object. Throw an error if the two iterators belong to different collections. mixed index() Should return the current index. mixed value() Should return the current value int has_previous() Return true if the iterator can move one step backwards. int has_next() Return true if the iterator can move one step forwards. It have the same use as '!(). collection get_collection() Return the collection this iterator iterates over. Optional void set_value(mixed value) Set the value of this iterator. This method should only be available if it is possible to set the value via an iterator. Optional void add(mixed value) Add a new item to the collection after the item the iterator currently is pointing at. This method should only be available if it is possible to add entries via the iterator Optional mixed remove() Remove the item the iterator currently is pointing at and move to the next item. This method should only be available if it is possible to remove entries via the iterator 3.2. OrderedIterator An OrderedIterator is an iterator working on an OrderedCollection. It has two characteristics, first it traverse the collection in the same order each time it is traversed, if the there hasn't been any changes in the collection, beginning with the item with the lowest index and ending with the item with the highest index. Secondly it is possibly to say that an iterator is less then or greater then another iterator. int(0..1) '<(OrderedIterator iter) Return 1 if iter is positioned after this iterator, otherwise 0. Throw an error if the two iterators belong to different collections. Int(0..1) '>(OrderedIterator iter) Return 1 if iter is positioned before this iterator otherwise 0. Throw an error if the two iterators belong to different collections. 4. Index If a type could be used as an index in an OrderedCollection then it must be possible to use the following operations on it. '== If the two indexes a and b is equal it should return 1 otherwise 0. The following rules must also be satisfied. a == a must be true a == b implies b == a !(a == b) implies a != b a == b and b == c implies a == c '< If the index a is ordered lower than b it should return 1 otherwise 0. The following rules must also be satisfied. a < a must be false a < b implies !(b < a) a < b implies (b > a) a < b and b < c implies a < c '> If the index a is ordered higher than b it should return 1 otherwise 0. The following rules must also be satisfied. a > a must be false a > b implies !(b > a) a > b implies b < a a > b and b > c implies a > c

SDL
by David Hedbor ＠ Pike developers forum 04 May '04

04 May '04

I have now implemented and checked in SDL.Surface->set_pixel and get_pixel methods. Note that they do no boundary checking so if you write outside the surface... Well, go figure. I could add it but I'd rather avoid any checks I can for performance reasons...

ADD_FUNCTION() macro on pike 7.5 ?
by Xavier Beaudouin 31 Mar '04

31 Mar '04

Hello there, Does ADD_FUNCTION macro still works outside the program scope on the module level in a Pike C module (not in a cmod) ? We have currently issues in our Caudium C module... and it seems that the following code has stopped to work : main.c /* ... */ void pike_module_init( void ) { /* some other add_function_constant() */ add_function_constant( "http_date", f_http_date, "function(int|void:string)", 0); /* */ init_external_module(); /* */ } in external.c we have : void init_external_module (void) { ADD_FUNCTION("whatever",f_whatever, tFunc(tVoid, tInt), 0); } Before (on 7.2 and in 7.4) it has used to work, but today on Pike 7.5 it has suddenlt stopped to work... Is this normal ? /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader.

Calendar question
by David Gourdelier 30 Mar '04

30 Mar '04

Hi again, It seems to me that the autodoc of the Calendar module is incorrect or there is a problem in the Calendar.Time* classes. The doc say you can use Calendar.TimeRange("unix", int unixtime) but when I try with either pike 7.5 or 7.2, I have: > Calendar.TimeRange("unix", time()); Calling undefined function. ISO.TimeRange: TimeRange()->create_unixtime_default(1080599245) /usr/local/pike/7.2.504/lib/modules/Calendar.pmod/TimeRanges.pmod:81: TimeRange()->create("unix",1080599245) ISO: ISO->TimeRange() -:1: ___Foo4711() > Calendar.TimeRange("unix", time()); Calling undefined function. ISO.TimeRange: TimeRange()->create_unixtime_default(1080599068) /usr/local/pike/7.5.23/lib/modules/Calendar.pmod/TimeRanges.pmod:78: TimeRange()->create("unix",1080599068) /usr/local/pike/7.5.23/lib/modules/Calendar.pmod/TimeRanges.pmod:11: ISO->TimeRange() HilfeInput:1: HilfeInput()->___HilfeWrapper() There is the same problem with Calendar.Time.TimeofDay. When looking at the code it seems indeed that the create_unixtime_default function is not defined in either TimeRange nor TimeofDay classes but defined in clases that inherited these one. So I wonder if the doc lie or if the code is wrong ? I also changed the doc for http://pike.ida.liu.se/generated/manual/modref/ex/predef_3A_3A/Calendar/Tim…, replacing "unixtime" by "unix". / David

Changelog and newsletter
by Bill Welliver 30 Mar '04

30 Mar '04

Okay folks, here's the deal: I'll volunteer to periodically (4-6 times a year should developments dictate) put together a Pike Update. As I see it, things that would be worthwhile in such a production might include: Pike development updates (what's happening, what the plan is) Pike Tips Usage Articles Conference Information Pike-based application updates and information etc. In order to do this, I need some help. I know that there is at least a little resistance to the idea, but having a changelog updated as changes get made would really help me (and other potentially interested parties) figure out what is going on. The reasons I think that a changelog is necessary and beneficial include: 1. A new "feature" or change may involve 5 - 10 or more cvs checkins, the log entries of which may not hint at the actual change being made. 2. Sometimes, even those of us who might follow the changes religously might have trouble figuring out what's going on, or the significance of that change 3. Waiting until a release is made to find out what's happening, while dramatic, is really a bit of a problem from a planning perspective: people _using_ the software should really know what's changing as it happens. 4. Having an awareness of a change lets people plan for it when it's released 5. Allows interested parties to test and (heaven forbid) document the change, possibly helping you, the developer out. I know that there are some people who feel that this is just extra work. To those, I say that someone is making the entry at the end, why not take a few seconds and describe the change (and take credit for it) when it's added. Not every checkin will prompt an entry, only those that complete a change or addition. If there's any doubt about whether a change merits inclusion, err on the side of over documenting and include it. An example of a few changelog entries I have made that represent a few hours of work on my part: - SSL3 client can now present certificates to a server; server can request and validate a client certificate chain presented. (Bill Welliver) - SSL3 module now checks presented certificate chains for validity by examining effectivity, issuers, and completeness of certification chain. (Bill Welliver) - Added method Tools.X509.verify_certificate_chain() that can verify the validity of a chain of X509 certificates. (Bill Welliver) This took me a total of 2 minutes to do, and might have taken less if the work were fresh in my mind. The third entry was one I included that would probably be cut from a release change log, but is certainly not wasted space. I'd like to see a policy added for 7.7 that says if you check in a completed new or changed feature (module, major work, language behavior, etc), you add a brief entry describing what you've done. Any thoughts? Who can make this happen? If anyone has any comments or would like examples of what I envision, please feel free to contact me. Thanks, Bill

Looking for translators
by David Gourdelier 29 Mar '04

29 Mar '04

Hi, The Camas team is looking for translators willing to translate the next Camas release in the language you know. For now the languages for which we have an up to date translations are: . English . French . Spanish . Polish And thus the Camas team is looking for anyone who knows a language except these. Mainly we are looking for: . German . Italian * . Swedish * . Finish * . Czech * . Dutch * . Estonian * . Hungarian * . Portuguese * . Russian The languages with a * are languages for which the translation is not up to date for this release. The translation is very easy and it'll require you only a text editor and a few minutes. If you are willing to translate, just send an email to me and I'll send you a file that you'll just need to translate and send me back. Thank you for your help. Best regards. -- David Gourdelier

pike -t
by David Gourdelier 28 Mar '04

28 Mar '04

Hi, I have a strange problem with pike -t in 7.5 and Caudium. When I start Caudium with -t, I have the following error at compile time: /usr/local/pike/7.5.23/lib/modules/Protocols.pmod/HTTP.pmod/Session.pike:1005 Error: Cannot inherit program which is not fully compiled yet. The strange thing is that it doesn't happen if I do pike -t -e 'Protocols.HTTP.Session;' for example. There is a backtrace attached to this mail and as you can see the error is generated from Pike itself (compile_error). Do you have any ideas ? Thank you for your help. / David Gourdelier
