1 mo: ribasushi: are you pro or con wrt the extended join conditions?
2 [18:22] ribasushi: totally pro, but con scalarrefs
3 [18:22] ribasushi: and I'm a horrible designer
4 [18:23] ribasushi: so I say "tell me what to write and I'll write it better than you would"
5 [18:23] mo: and what about a second hashref which is parsed like search()?
6 [18:24] ribasushi: mo: show me what you mean
7 [18:25] mst: join => { 'foo' => { -attrs => { ... } }
8 [18:25] mo: has_many(accessor => 'CLASS', { foreign,self stuff }, { 'me.foo' => { '>' => 'accessor.bla' } }
9 [18:26] mst: and -attrs can then override the rel's defaults
10 [18:26] ash: mo: there's already a 4th arg to rels
11 [18:26] mo: mst: where would you put that in the has_many call?
12 [18:26] mst: mo: that's for search() syntax
13 [18:26] mo: ok so add another method next to has_many
15 [18:27] mst: I'm talking about overriding the join stuff in search()
16 [18:27] mo: I'm talking about extended join conditions
17 [18:27] mst: I am aware of that. I'm saying "we should do this at the same time"
18 [18:27] pktm hat den Chatroom betreten.
19 [18:28] ribasushi: I'm talking about both - it should be just like attrs - specifiable both on relationship and on searches
20 [18:28] mo: mst: what would you propose?
21 [18:28] ribasushi: and overridable accordingly of course
22 [18:28] mo: syntax I mean
23 [18:28] mst: does SQL::Abstract have a { -ident => 'foo.bar' } yet?
24 [18:29] ribasushi: explain?
25 [18:29] pktm: How do I (efficently) select the complement of a relation? I have products and categories, and I want to know the products, that are not assigned to a specific category. So what is complement( $category->products() )?
27 [18:29] mst: pktm: you mean not assigned to category X
28 [18:29] mst: pktm: or not assigned to -any- category ?
29 [18:29] pktm: not assigned to category X
30 [18:29] robkinyon: mst: I think I have a solution
31 [18:30] robkinyon: it's completely backwards INcompatible
33 [18:30] ribasushi: robkinyon: not interested
34 [18:30] robkinyon: but it solves all problems
35 [18:30] robkinyon: (including world peace)
36 [18:30] mo: ribasushi++ # who cares about backwards compat
37 [18:31] robkinyon: why don't we just allow the full search() syntax?
38 [18:31] ribasushi: mo: I don't give a fuck frankly, I just want *my* code to work
39 [18:31] robkinyon: it's being used to build a search() anyways
40 [18:31] arcanez: mst++ # being done
41 [18:31] mst: robkinyon: that would be -exactly- my plan
42 [18:31] mo: robkinyon++
43 [18:31] mst: we add an extra relationship attribute
44 [18:31] mo: what about self and foreign?
45 [18:31] mst: that's a subref
46 [18:31] mst: that's supplied @_ of ($rs, $lhs_alias, $rhs_alias)
47 [18:32] mst: and is expected to return a chunk of search() params
48 [18:32] dhoss: arcanez: get your GSoC stuff figured out yet?
49 [18:32] robkinyon: and we implement the current code in terms of that?
50 [18:32] ribasushi: mst: *this* I love
51 [18:33] robkinyon: i can get behind this
52 [18:33] robkinyon: regardless of use-case need
53 [18:33] robkinyon: because this is a sane API
54 [18:33] mst: it eliminates the "deep finding of self/foreign in SQLA" problem
55 [18:33] mst: which was why I didn't want to do it before
56 [18:33] zamolxes hat den Chatroom verlassen. (Quit: leaving)
57 [18:33] mst: if the user wants to be clever, they get to handle that themselves
58 [18:33] robkinyon: it also eliminates the need for two SQL specification languages
59 [18:33] ribasushi: add_relationship receives two modes - either foreign./self. (for backcompat) or a regular search
60 [18:33] robkinyon: and standardizes on the one that we're actually working on
61 [18:33] ribasushi: and the helpers get adjusted to produce new code
62 [18:33] ribasushi: and then join_cond can override all that
63 [18:34] ribasushi: mst: that's what you mean?
64 [18:34] mst: sub { my ($rs, $self, $foreign) = @_; { "${self}.foo" => { '>', "${foreign}.bar" } }; }
65 [18:34] nigel hat den Chatroom verlassen. (Quit: nigel)
66 [18:34] mst: add_relationship can DWIm based on if it gets a hashref or a subref in the join position
67 [18:34] robkinyon: what about \{ ... } ?
68 [18:34] mst: robkinyon: stop. think.
69 [18:34] robkinyon: if it receives HREFREF, then it's just a search() args?
70 [18:34] mo: what about an object
71 [18:35] robkinyon: and that maps closely in terms of how things work right now to pass through
74 [18:36] mst: we can't just provide raw search args
75 [18:36] mst: otherwise we have to recurse the full SQLA tree to substitute aliases
76 [18:36] mst: which is a horrible job
77 [18:36] mst: part of the reason for SQLA2 is to have somewhere we can do non horrible AQT comprehensions
78 [18:36] mst: hence: subref
79 [18:36] ribasushi: hear hear
80 [18:36] mst: which delegates the problem to the user
81 [18:36] arcanez: dhoss: plan to work on it once I watch a rather subdued mst
83 [18:37] dhoss: subdued mst? that's not fun...
84 [18:37] robkinyon: subref it is
85 [18:37] mst: we don't need to modify the helpers though
87 [18:37] arcanez: his dbix::class talk, wasn't it at 8am?
88 [18:37] mst: resolve_join should switch to generating basic SQLA
89 [18:37] mst: the only reason it ever didn't
90 [18:37] mst: was SQLA had no way to represent identifiers on the RHS
91 [18:37] mst: and the subref should just return SQLA
92 [18:38] fade hat den Chatroom verlassen. (Quit: Leaving.)
93 [18:38] ribasushi: these are implementation details which do not matter much
94 [18:39] ribasushi: sqla does not support FROM at all, it is all done in Hacks anyway
95 [18:39] ribasushi: talking about 1.5 of course
96 [18:39] robkinyon: so, we agreed on a design?
97 [18:40] solar_ant hat den Chatroom betreten.
98 [18:40] mst: robkinyon: right, but this cleanup
99 [18:40] mst: ribasushi:

101 [18:40] Psyche^ hat den Chatroom betreten.
102 [18:40] mst: we didn't yet becaue ldami pointed out, quite rightly, that the DBIC interface was inconsistent

105 [18:40] Psyche^ heißt jetzt Patterner.
106 [18:40] ribasushi: mst: of course, I do try to isolate chunks as I go
107 [18:41] robkinyon: which means that ash and i better beat up SQLA2 quickly
108 [18:41] ribasushi: but anyway - can someone type up an actual example for me
109 [18:41] ribasushi: one for add_relationship
110 [18:41] ribasushi: and one for search()
111 [18:41] ribasushi: something I can turn into a test (or if someone submits an is_same_sql test - that'd be golden)
112 [18:41] robkinyon: search() doesn't change here, does it?
113 [18:41] ribasushi: sigh
114 [18:42] ribasushi: of course it does - there's no point to do it otherwise
115 [18:42] robkinyon: i thought the point was to unfuck add_relationship()?
116 [18:42] ribasushi: i.e. not "changes" but supports an extra attribute
117 [18:42] robkinyon: no ....
118 [18:42] robkinyon: mst?
119 [18:42] purl: i guess mst is wrong it is a hard way to write handles => qr/.*/ or a young whippersnapper from nigel's exalted position or planning to port the world to moose or working on serializable meta with another approach or simply a wanker or a bot or really a peach or a blunt or faster than light or a bitter betty or ~13 times better than sex
120 [18:42] ribasushi: robkinyon: how do you supply bind values to a join if you set it on the relationship in stone
121 [18:43] robkinyon: Scalar::Alias?
122 [18:44] robkinyon: Scalar::Defer
123 [18:44] purl: i heard Scalar::Defer was one of them, is a nice module, does nice stuff
124 [18:44] ribasushi: robkinyon: Rainbow::Pony ?
125 [18:44] ribasushi: be practical
126 [18:44] arcanez: "are we fucked" "no because we didn't get to the pub in time to pull"
127 [18:44] arcanez: hahahahaha
128 [18:44] purl: LOLCON 5 reached.
129 [18:44] robkinyon: ribasushi: Scalar::Defer is practical
130 [18:45] robkinyon: at least mst has thought so in the past
131 [18:45] mst: I like Data::Thunk better but nothingmuch is convinced it can't be 100% fixed and won't explain why well enough for me to try and prove him wrong
132 [18:45] robkinyon: ribasushi: the point is that we want to defer resolution of the bindvars
133 [18:46] mst: that's easy
134 [18:46] robkinyon: that way, it becomes purely an add_relationship problem
135 [18:46] mst: no rob, it doesn't
136 [18:46] robkinyon: and search() is unaffected
137 [18:46] mst: searhch needs extending as well
138 [18:46] robkinyon: to do what?
139 [18:46] mst: { join => { 'foo' => { -attrs => { join_args => [ 3 ] } } }
140 [18:47] arcanez: mst: who's writing HashMap for moose?
141 [18:47] ribasushi: mst: how about overrides on the spot? or that's too much foo?
142 [18:47] ribasushi: I mean search to override the entire relship construction, only self. foreign. remain static
143 [18:48] robkinyon: either way, have fun
144 [18:48] • robkinyon & # errands
145 [18:48] ribasushi: or hell - join without a relationship altogether
146 [18:48] ribasushi: as in the case of self-join to figure out "last row"
147 [18:48] mst: has_many('foo', $f_class, sub { my ($rs, $self, $foreign, $arg) = @_; { "${self}.id" => "${foreign}.bar_id", "${foreign}.weight" => { '>', $arg } }, ...);
148 [18:48] mst: so you get
149 [18:48] ribasushi: mst: I get that part
150 [18:48] mst: LEFT JOIN foo ON me.id = foo.bar_id AND foo.weight > 3
151 [18:49] ribasushi: I'm saying how do you feel about search ({}, { join => { a definition that is not a relationship, but which will produce a join nevertheless } });
152 [18:50] ribasushi: example here: http://lists.scsys.co.uk/pipermail/dbix-class/2009-June/008095.html
153 [18:50] ribasushi: I don't need anything from the right side, I just need the join to limit the left side properly
154 [18:51] mst: anonymous joins will discourage re-use and completely fuck us introspection wise
155 [18:51] mst: I don't want to do that yet
156 [18:51] mst: we -will-
157 [18:51] ribasushi: fair enough
158 [18:51] mst: but I don't want to add too much stuff at once
159 [18:51] ribasushi: mst++ #conservatism
160 [18:53] mst: mo: so, you up for writing tests for this?
161 [18:54] mo: I think David Ihnen is up to it, I was just trying to bring this to _your_ attention
162 [18:54] ribasushi: except david ihnen is not reading this
163 [18:55] mo: so you have to convince him by mail
164 [18:55] mst: mo: so write up the conversation to an outline
165 [18:55] mst: and reply to the list saying "if somebody writes spec tests we can make it happen"
166 [18:55] mst: you don't have to be me to shout well volunteered
167 [18:55] mst: you just have to look them in the eye and have them believe you already know they'll say yes
168 [18:56] mo: I didn't get that add_relationship part
169 [18:56] mo: does it even matter?
171 [18:57] mst: without the add_relationship part none of this will work at all
172 [18:57] mo: but is it required for the tests?
174 [18:57] mst: how can you write tests for something that can't work?
175 [18:57] mo: so I have to call add_relationship in my test?
177 [18:57] mst: what the fuck are you talking about?
178 [18:57] mo: has_many calls add_relationship right?
179 [18:57] mst: this is the DBIC test suite
