Re: [Gallery-devel] Docs and stuff
From: Chris Kelly <ckdake@ck...> - 2006-09-28 23:52:08
Everyone definitely has their busy days/weeks/months/years. I know  
I'm certainly no exception (I think I can count the status emails  
I've sent on my toes). The new documentation proposals every time are  
certainly all useful but they are all different ways of doing things.  
None of them is perfect but none of them have seemed to be too wrong  
so far. I think someone just needs to take the ball and roll with it  
on one of them.  If there's not time for you to give it all of your  
time that's just how it is. If Michael or anyone wants to throw a few  
hundred hours at it, that would be great.

To clear one thing up for probably everyone, heres the deal with the  
tech-writers. In LV we "decided" (as if we hadn't decided  
before :) ):  We don't have them, we want them, someone should do  
something about this, lets make chris do it!  All I've done is ask  
around seeing if I could find a way to get some time from some people  
to do the actual writing of things and all I have is an e-mail  
commitment from some people to ask some students once we come up with  
something specific for them to do. So things are really almost the  
same as where they were last time. We need some structure to the docs  
so that we can figure out exactly what to get people to work on.  Is  
coming up with a task list for people something you have time for or  
should I start stalking others?

I guess we should cast to true if we don't succeed in getting the  
boolean version of that object.

I guess this is because com_object_cast() handler returns FAILURE:
See ext/com_dotnet/com_handlers.c, line 527, this is the line where it likely comes from.
And if the problem is in VariantChangeType() failing to convert the object to VT_BOOL, then it doesn't look like PHP problem.
I can't test it on Linux though, so this is just what I see in the sources.

Yes :-)
I just wanted to gauge whether it was a critical bug; it is (see my  
other mail regarding variants).

Re: [Gallery-devel] [PHP-QA] Bug in COM support in PHP 5.2.0 RC5
From: Wez Furlong <wez@ne...> - 2006-09-28 21:47:15
Tony,

Any idea why this is now an error?
Is something missing from the com extension?
If so, it needs to be fixed because one of the core features of the  
variant class is magically representing a variant bool, which can be  
interpreted as either true or false.

that check is redundant in PHP 5; if the object couldn't be created,  
an exception will be thrown.

Re: [Gallery-devel] [PHP-QA] Bug in COM support in PHP 5.2.0 RC5
From: Larry Menard <larry.menard@ro...> - 2006-09-28 21:15:15

   I originally found the problem like this:

  // Connect to database
  $dbc =3D new COM(...);

  // Check that it was successful
  if (! $dbc) { ...};

   We then reduced it to that one single line just for simplification.

From: Wez Furlong <wez@ne...> - 2006-09-28 20:49:33
com, variant and dotnet objects are all the same really.

The question is, why are you comparing them with bool in the first  
place?

--Wez.

[Gallery-devel] Bug in COM support in PHP 5.2.0 RC5
From: Larry Menard <larry.menard@ro...> - 2006-09-28 19:24:55
Attachments: Message as HTML
   Hi folks.

   I believe I've found a bug in PHP 5.2.0 RC5.  When I try to perform =
boolean operation against an object of type COM, I get an error that it =
cannot be converted to boolean.

   Simplest repro script:

  <?php
  $dbc =3D new COM ("WinNT://Domain";);
  var_dump(bool($dbc));
  ?>

   Error produced is:

  Catchable fatal error: Object of class com could not be converted to =
boolean

   On PHP 5.1.4 it returns:

  bool(true)

   My environment is Windows XP SP2.  Running "php -v" returns:

  PHP 5.2.0RC5-dev (cli) (built: Sep 22 2006 04:22:26)
  Copyright (c) 1997-2006 The PHP Group
  Zend Engine v2.2.0, Copyright (c) 1998-2006 Zend Technologies

   As this is Windows, I'm running precompiled binaries ao I can't test =
any source code changes, but I'd be happy to test new binaries if you =
wish.

   Thanks.

[Gallery-devel] Docs and stuff
From: Christian Mohn <h0bbel@p0...> - 2006-09-28 19:20:05
Attachments: smime.p7s
First of all, sorry for not sending status emails, nor really doing any work
on docs. The last few months has been incredibly busy at work and I really
don't have much energy left when I get home. That situation is unlikely to
change over the next couple of months too.

After reading the meetup notes after LV, I was a bit bummed out by reading
"Lack of documentation/organization-of-documentation negatively
differentiates Gallery from other projects". That really got to me, but I do
know it's true and I have not been doing a great job with it.

The more I think about the more I realize that I'm really not (at least not
currently) able to provide the documentation site the attention it needs. 
Every time we have discussed organization of the content I end up more
confused than before, and new angles/proposals are put forward every time. 

I do want to spend time on docs, and I do want to help in any way I can, but
perhaps someone else should take charge and get a good organizational
structure and roadmap settled? As long as I know what I'm doing, I would be
happy to help reorganize the contents. Perhaps we should use Michaels
"Documentation and support are two areas I'd be a good fit in" skills and
let him have a go at trying to head out the docs team, if he's interested.
If not, are there any other candidates or should we try to recruit someone
who could do it instead of me? Perhaps someone in the mediawiki organization
would bite, I don't know.

Also, I do feel kinda left out of the loop in the tech writers stuff. I
would have thought that I would have been involved in that, besides reading
about it in the LV meeting notes. Even if I'm doing a bad job of being in
charge of docs, I think I should have been asked about it at least. I would
have applauded it of course, so don't worry. Now, there, I said it. ;-)

Don't worry, I'm not angry, irritated or otherwise annoyed, I'm just
realizing realities here as you all have done way ahead of me anyway. I'm
not going anywhere either.

* Added progress bar for Update Plugin List step
* Mostly done with having DP support 3 different repositories (official,
   experimental and community).  Will have that done by tomorrow.
* Built 2.1.2 packages and pushed them to GMC.  GMC has a complete set
   of official and experimental packages.  Updated the
   gmc_repository.module to support them properly.
* Identified performance problem with new data cache pruning code

GMC:
* Enabled greylisting to cut down spam.  Seems to be working well so

   + New block setting for keyalbum to show keyword cloud
   + Option in exif/iptc module to set item title from iptc objectname
- Refactor thumbnail module to use 'thumbnail' operation instead of

[Gallery-devel] block parameters
From: Alan Harder <alan.harder@su...> - 2006-09-27 20:20:22
Hi all-
Came across an issue with Smarty, not sure what the right solution is.

We include blocks with code like:
{g->block type="module.BlockName" paramName="value"}
or
{g->block type=$block.0 params=$block.1}

In both cases the tpl for the block is included, with the given
parameters merged into all existing smarty variables.
This means the block tpl can access both: {$paramName} and {$user.userName}

Unfortunately it also means that theme tpl like this is interpreted
as block parameters:
{foreach from=$links item=link}..{/foreach}
{assign var="blocks" value="randomAlbum"}
{g->block type="imageblock.ImageBlock"}
This is the same as blocks= and link= inside the g->block.

Carbon theme happens to use a variable in album.tpl called "link",
so imageblocks on the album page create invalid links.
We can change this tpl to a different variable name, but it's
unfortunate that themes have to be careful not to use any variable
name that matches a parameter name for any block out there...

We could include the block tpl with only the given parameters,
but then the block can't access things like $user or $theme.item,
so that won't really work.

Perhaps we should cache the _tpl_vars at the start of fetch()
(before theme.tpl starts) and merge that cached value with given
params to use for block tpl.  Then anything from theme.tpl, album.tpl,
etc is not included.  Not sure how to achieve this though.

	- Alan

Re: [Gallery-devel] Patch GalleryDataCache for obsolete cache data

Maybe there is a third option;

3 extend a little so we can get a bit more performance without going into=
 the
advance mysql or changing a lot.
- Add COLUMN boolean isEmpty, default isEmpty to false
- Set isEmpty to true and value to NULL on the UPDATE in the cleanup
- Set isEmpty to false on putPageData calls

- Add INDEX [isEmpty, timestamp] to speed-up the cleanup code
We might want to include the userId in there as we need choice between gu=
est
and non-guest when cleaning.

This will limit the rows a lot more then we are currently doing and is mu=
ch
faster and easier to implement.

You're right, we might as well fix it the way we originally wanted.

I looked into the "index of length 1 on TEXT column" option a little =
more
closely.
- MySQL supports it out of the box
- PostgreSQL < 7.4 requires us to define a function first and then to =
use
that function in the CREATE INDEX command.
- PostgreSQL >=3D 7.4 needs a function call in the CREATE INDEX command.
- DB2 supports it through a Index-Extension. We first need to create =
such an
extension and then use it in the index command.
- MS SQL does not support this.
- Oracle supports it through a function-based index.
(- SQLite does not support it)

I don't like the fact that we use quite advanced SQL features in G2. It
complicates portability and maintainability.
In this case, we should look for simpler alternatives like
- Instead of indexing a substring of a TEXT column, rather add an =
additional
column that signals whether the value is NULL (boolean)
INDEX over [this column, timestamp] (in that priority order)

As to introducing a non-composite PK such that we can do a UPDATE =
limited to
e.g. 100 rows:
- The new PK column could be a hash over userid, timestamp + some random
number (we shouldn't hash the value for performance).
- Then we can apply the non-mysql fallback solution of SELECT with limit =
100
and then UPDATE with PK IN (...); for the other DBMS.

Bottom line:
There are 2 alternatives:
1. Just add an index such that the existing code works.
- INDEX over [timestamp, userId].

2. A lot changes to make it more efficient.
- Add COLUMN boolean isEmpty, default isEmpty to false
- Add INDEX [isEmpty, timestamp] to speed-up the cleanup code
- Set isEmpty to true and value to NULL on the UPDATE in the cleanup
function.
- Add COLUMN id char(32) with UNIQUE INDEX
- ON INSERT, generate id based on md5(timestamp + userId + rand(..))
- ON cleanup, use UPDATE + LIMIT for MySQL =E0 la GallerySession.
- ON cleanup, use SELECT + LIMIT, UPDATE WHERE id IN (...,...) for other
DBMS =A3 la GallerySession.

The second option would sure be more efficient, querying less rows etc.
Since the table has an ever-increasing cardinality, we should probably =
opt
for option 2.

Votes?

Not sure if the second option is required, might as well go for option =
one.

Hi,

If we are going to modify the table we might as well correct this problem=
 in a even better way.

add a id column and make it primary index.
make the currenty primary index a regular Unique index.
add a index to optimeze a select obsolete cachemap entries, this requires=
 a combined index on value limited to 1 size and timestamp. Is this possi=
ble limiting index on value, it is with mysql but is it with the other db=
's gallery 2 supports?

That way we can limite the update to ?100? rows per putPageData() like th=
e session cleaner.

Kind regards,
Michiel
