[PHP-DEV] Need some ZE2 functions exported.
im trying to do some namespace related experimentation but im getting the
following link errors :
i18n_util.obj : error LNK2001: unresolved external symbol
_zend_init_namespace
i18n_util.obj : error LNK2001: unresolved external symbol
_zend_initialize_class_data
i18n_util.obj : error LNK2001: unresolved external symbol
_zend_do_inheritance
i18n_util.obj : error LNK2001: unresolved external symbol
_zend_register_functions
any chance of exporting the offenders here ? here's precisely the code im
using (modified from marcus):
/* {{{ register_interface */
/* You will have to alloc the pce before the call and namespace_entry must
be valid */
zend_class_entry* register_class(zend_namespace *namespace_entry,
zend_class_entry *parent_ce,
char *class_name,
zend_function_entry *functions
TSRMLS_DC)
{
int name_length = strlen(class_name);
char *lowercase_name = zend_strndup(class_name, name_length);

[PHP-DEV] Possible leak in zend_llist ?
hi,
im reviewing the source code of zend_llist.c and it appears there may be an
inconsistency in the way deletions are handled which may cause leaks.
in particular the macro DEL_LLIST_ELEMENT only releases memory for a node
if a destructor is specified for the zend_llist, whereas memory is always
allocated for the node when an insert is performed.
this macro is used only in zend_llist_apply_with_del and
zend_llist_del_element. note that
no other code in the file assumes that the destructor function is
responsible for the deallocation of the _node_
compare DEL_LLIST_ELEMENT (snippet)
if ((l)-dtor) {\
(l)-dtor((current)-data);\
pefree((current), (l)-persistent);\
}\
with zend_llist_destroy
if (l-dtor) {
l-dtor(current-data);
}
pefree(current, l-persistent);

i've noticed that in ZE2 that object autodestruction (ala zend_objects_store_call_destructors) happens _after_ a module's RSHUTDOWN, which causes some interesting lifetime management issues in an extension im writing. in particular, the Zend objects wrap some in-memory structures from a library which handles its own cleanup (the cleanup function is called in RSHUTDOWN). forgive me if this reveals my ignorance of engine internals, but shouldnt the object destruction sequence precede a module's request shutdown ? l0t3k -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

I have always wondered, how do you pronounce L0t3k? actually low-tech. most days i dream of woodworking g Seriously, if you are duplicating Metabase's effort, but in C, why not work with the Manuel Lemos then? This will fix any speed issues that Metabase has, and you will get his feedback. the DB abstraction problem is a much larger one, which Manuel (and yourself) have been struggling against with serious handicaps. for instance, one of the reasons Manuel had to put so much work into Metabase is that the original extension writers did not provide metadata which is readily available from the database itself, or the metadata supplied is inconsistent across back-ends. the current database extensions were written as needed, so there was no over-arching and unifiying design. im attempting to consolidate and refactor the code in the existing extensions into a framework which makes driver development much easier and a lot more flexible. the upshot is that features can be implemented in the core that are immediately available across DB backends (like disconnected resultsets, resultset serialization, and XML import/export which is nearly done). in addition, features like connection management can be handled consistently across supported backends. Many db abstraction classes I have seen are skewed towards mysql/postgresql, so prove to be useless when migrating to mssql or oracle. ive done quite a lot of legwork on this, and i think i have a framework which accomodates everything from MySQL to Oracle. i did MySQL first because 1) the API is simple 2) i needed to quickly write a driver to test some basic design decisions (navigation and bulk-fetching). Manuel really knows a lot about databases and can teach everyone a lot about these issues. Or if you or anyone else would like to port ADOdb to a C extension, let me know. i actually wrote to Manuel about this last summer, but he was (justifiably) skeptical about the doability of the project and the prospects of its adoption, given its scope and the fact that most people were comfortably either using the base extensions, or something like Metabase, PEAR or ADODB. instead of long discussions, i decided to wait until i had something tangible to demonstrate. im very near to that point right now. note that i dont think that Metabase or ADOdb will necessarily go away if this extension works out. there are things that you and Manuel do that i think belong in user-space and not in an extension. for instance your sequence emulation code modifies the DB schema, which crosses the line of an access layer. also Manuel's schema abstraction and transformation is another example. i only really care at this point about data and metadata acess abstraction. what it means though, is that your PHP code will be considerably smaller and faster ( i think i can eliminate the need for at least 65% of Metabase's code). l0t3k -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

There is currently an effort underway to merge Metabase with PEAR DB. I have just commited the first code into the pear cvs (package is called MDB for now). The merge is still not complete. But the idea was that this merged DB abstraction layer could down the road be ported to C ... the sooner the better. ive downloaded alreay. i keep track of development of PEAR::DB, Metabase and ADOdb. In terms of how to abstract things, its quite obvious that Metabase is very far ahead (is there even something similar in other languages?). So I guess Metabase, or MDB when its ready, will be the best place to turn to if you seek this knowledge for a C Extension. the abstraction work is primarily done, the blob spec is the main thing pending. the hard part now is producing a set of test drivers.

[PHP-DEV] Advice on design issues (long)...
im looking for opinions on two OOP related design issues for code im targeting to PHP5. (1) im writing (actually porting) a DateTime class which matches the functionality of the Java Date class. it actually does much more, and that's the issue. in looking at the Javadocs reference page for Date, a lot of what i have scheduled for my class has been deprecated in Date for various reasons. in specific, display formatting, parsing and interval math are moved into other classes. what do you think about having this functionality in one class or splitting. i agree somewhat in a separation of concerns, but one reason i tend not to like Java for web development is the fact that there can be too many classes involved in getting basic things accomplished. (2) im working on a database access abstraction, again inspired by Java and JDBC (MySQL driver is written and works, BTW). in Java you have the Resultset.getXXX methods which gets the value of a given column as a particular type. Java of course is strongly typed, whereas PHP is not. Is it useful to implement the getXXX methods natively. i lean toward it primarily because 1) folks coming from Java will be right at home 2) sometimes you need to enforce a particular return type coming from a column 3) Metabase does it for portability, and although it can be done in PHP, its more efficient to do it in the extension. On the downside there is the issue of bloat.

It would be implemented something like the user-mode session module

and register it as a wrapper using a new user-space function called
file_register_wrapper(string $protocol, string $classname).
file_register_wrapper would fail if the wrapper is already registered.
The php_stream_open_wrapper function would create an instance of the
class and then call it's methods when the equivalent methods in
the php_stream_ops structure are called.
This would allow some really cool things, like defining a custom
protocol and then passing that custom URL around to all sorts of
PHP functions (fopen(), copy(), extension functions that use wrappers)
and have them handle it without even noticing that it's implemented
in PHP code.
Comments please!

Klaus, anything zval * put in a symboltable is automatically managed. Currently it looks to me, that I don't need to free zvals which I have exported to a symbol table, because PHP already frees the zval on module shutdown. Is that correct? Or do I need to remove the zval from the symbol table and then free the zval manually? How it is done correctly? -- Bye, K http://www.ailis.de/~k/ [A735 47EC D87B 1F15 C1E9 53D3 AA03 6173 A723 E391] (Finger [EMAIL PROTECTED] to get public key) -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] Re: Get object name
you can do this only with a not-so nice hack. essentially you have to
manually search the active symbol table stack for a zval * which equals your
variable. zend_hash_find wont help you, since you're doing a reverse
lookup. so the process is something like (totally OTTOMH)
HashTable *table = EG(active_symbol_table);
char *name_im_looking_for = NULL;
while (table !name_im_looking_for) {
if (name_im_looking_for = find_name(table, zval
*zval_ptr_im_looking_for)) break;
table = get_prev_symbol_table(); /* you're on your own here - i have
no idea how to do this*/
}
static char *find_name(HashTable * table, zval *zval_ptr_im_looking_for)
{
zval **entry;
zend_hash_internal_pointer_reset(table);
while (zend_hash_get_current_data( hash, (void**)entry) == SUCCESS) {
if (*entry = zval_ptr_im_looking_for) {
char *string_key;
ulong num_key, key_len;
if (HASH_KEY_IS_STRING ==
zend_hash_get_current_key_ex(hash, string_key, key_len, num_key, 0,
NULL)) {
return string_key:

Subject: Get object name
Hi,
I need to acces the name of an object in a class method written in C. How
can
I do this? Example:
I have the following PHP code
$Test=new CMyClass();
$Test-print_obj_name();
and I have the following print_obj_name()-method written in C:
ZEND_NAMED_FUNCTION(cmyclass_print_obj_name) {
zend_printf(%s\n,doSomethingMagic());
}
How can I do the doSomethingMagic() part so my method prints the object
name
(Test)? I can access the CLASS name with
getThis()-value.obj.ce-name
but I need the variable name of the class instance (Test in this case).
How
can I do this?

Bug description: use of references in arguments with defaults
I would like to be able to define a function with a
referenced argument as well as give it a default value.
function foo($bar = NULL) {}
So, what will it reference, you ask? Nothing. I just want
the argument to be optional, but to reference if there is
an argument supplied. So, it's less of a default that's
needed for references, more the ability to have the
argument be optional.
This would make me so happy.

Re: [PHP-DEV] Re: Bug #13700: Database Abstraction API
Manuel, part of the effort to write an abstraction layer is to factor out common code and patterns and move this into a common base so that higher level development becomes easier. a good example of this is persistent connections handling, which is handled almost identically in all the db extensions. another example is code implementing the different varieties of fetching (fetch_array et al). At the PHP level there are common patterns of use which may be aided by support at lower levels. bulk fetches and resultset iteration to construct markup and resultset caching are examples. in addition there are features which when implemented at a core level, creates value which is automatically available to users of each backend. while they can be implemented in PHP itself, but make better sense as core functionality from a performance standpoint. also, there is functionality not covered by the existing APIs, hence unavailable totally to PHP ( eg fetching multiple resultsets from the same query ). in other words, i dont see the development of an abstraction layer in C and PHP as competing propositions. the C layer just allows PHP developers to be more productive and focus on higher levels of application development. the current PHP abstractions fill the need not only of functionality, but of code/work style and aesthetic preference. that need will persist whatever happens at engine level. One of the biggest pluses of PHP is that implementation of new functionality is magnitudes faster than in C. if a necessary feature is needed, we dont have to depend on the release cycle of PHP to have it included in a distribution. things in this business happens too quickly. and on a personal/ideological level, many of the features included in Metabase belong at the engine level (not that theyre not necessary). for instance, i think anything touching automatic schema modification or generation should absolutely be in user-space. use of PHP or standard extensions should not automatically impose a methodology on a user. i like the work you did with Metabase and think that the work being done on a new extension will make your work easier by being able to focus more on portability issues, which is Metabase's strength (imo) and which should be dealt with in PHP. l0t3k Manuel Lemos [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: [PHP-DEV] For Wez : Stream Abstraction over a String
Andrei, Perhaps I'm missing something, but can you explain how this is better than what we have now? the power of abstraction g i'll give you an example of why i want it. im working on resultset caching in a DB astraction layer, and im giving the user the option of saving to XML or a more compact format. i'd like to give the user options as to how and where the data is stored. if the user has file system access and wants to do it that way, then fine. if however, they want to use the session mechanism and stick it into a zval string, then its gravy. the point is to allow for flexibility. in any case, its a pain to have to write two sets of code to write to a 'proper' stream (file or sockets) , and to write another set of routines to store to a string. with a unified approach, you get the flexibility you need all for free. l0t3k Andrei Zmievski [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

[PHP-DEV] For Wez : Stream Abstraction over a String
Wez,
im not sure if you had planned to do so, but it would be ultra nice to
have a stream implemented over an expandable string (for instance wrapping
Sascha's smart-strings). its one of the niceties i like in Delphi - you can
do something like this :
InitialString := 'This is some data';
str := TStringStream.Create(InitialString);
str.Write(hello, sizeof('hello'));
fileStream := TFileStream.Create('license.txt',fmOpenRead);
str.CopyFrom( fileStream, fileStream.Size );
fileStream.free;
output := str.DataString;
writeln( output );
etc.
this would be helpful for an extension im working on. i'd rather have only
one 'logical' way of generating output, as opposed to having two separate
methods for files and strings.
