2024-09-04`result_view()`'s table's `close()` method need not be further wrapped.Nat Goodspeed
`LL.setdtor(desc, table, func)` eventually calls `func(table)`. So the `close()` method on the table returned by `result_view()` can be directly passed to `setdtor()`, instead of wrapped in a new anonymous function whose only job is to pass the table to it. Moreover, there's no need for the table returned by LLInventory.lua's `result()` function to lazily instantiate the `result_view()` for `categories` or `items`: neither `result_view` will fetch a slice unless asked. Just return `{categories=result_view(...), items=result_view(...), close=...}`. This dramatically simplifies the `result()` function. Since that table also defines a `close()` function, that too can be passed directly to `setdtor()` without being wrapped in a new anonymous function.
2024-09-04Instead of traversing all calling cards, pick a selected few.Nat Goodspeed
Make test_LLInventory.lua directly select from the calling_cards result set, instead of first copying all names to a separate array.
2024-09-03Use Lua result-set logic for "LLFloaterReg"s "getFloaterNames" op.Nat Goodspeed
This is the query that produced so many results that, before we lifted the infinite-loop interrupt limit, inspect(result) hit the limit and terminated.
2024-09-03Generalize Lua-side result-set machinery for other use cases.Nat Goodspeed
Change `result_view()` from a simple function to a callable table so we can add conventional/default functions to it: `result_view.fetch()` is a generic `fetch()` function suitable for use with `result_view()`, and `result_view.close()` is a variadic function that closes result sets for whichever keys are passed. This arises from the fact that any `LL::ResultSet` subclass is accessed generically through its base class, therefore we don't need distinct "getSlice" and "closeResult" operations for different `LLEventAPI` listeners. (It might make sense to relocate those operations to a new generic listener, but for now "LLInventory" works.) That lets `result_view()`'s caller omit the `fetch` parameter unless it requires special behavior. Omitting it uses the generic `result_view.fetch()` function. Moreover, every view returned by `result_view()` now contains a close() function that closes that view's result set. The table returned by LLInventory.lua's `result()` function has a `close()` method; that method can now call `result_view.close()` with the two keys of interest. That table's `__index()` metamethod can now leverage `result_view()`'s default `fetch` function.

At this point, inspect(landmarks) just returns "<userdata 1>".

2024-09-03result_view() now reuses same metatable instance for every table.Nat Goodspeed
2024-09-03Add test_result_view.lua; fix minor bugs in result_view.lua.Nat Goodspeed
2024-09-02Introduce result_view.lua, and use it in LLInventory.lua.Nat Goodspeed
result_view(key_length, fetch) returns a virtual view of a potentially-large C++ result set. Given the result-set key, its total length and a function fetch(key, start) => (slice, adjusted start), the read-only table returned by result_view() manages indexed access and table iteration over the entire result set, fetching a slice at a time as required. Change LLInventory to use result_view() instead of only ever fetching the first slice of a result set. TODO: This depends on the viewer's "LLInventory" listener returning the total result set length as well as the result set key. It does not yet return the length.
2024-08-31Give certain LLInventory queries an API based on result sets.Nat Goodspeed
Introduce abstract base class InvResultSet, derived from LLIntTracker so each instance has a unique int key. InvResultSet supports virtual getLength() and getSlice() operations. getSlice() returns an LLSD array limited to MAX_ITEM_LIMIT result set entries. It permits retrieving a "slice" of the contained result set starting at an arbitrary index. A sequence of getSlice() calls can eventually retrieve a whole result set. InvResultSet has subclasses CatResultSet containing cat_array_t, and ItemResultSet containing item_array_t. Each implements a virtual method that produces an LLSD map from a single array item. Make LLInventoryListener::getItemsInfo(), getDirectDescendants() and collectDescendantsIf() instantiate heap CatResultSet and ItemResultSet objects containing the resultant LLPointer arrays, and return their int keys for categories and items. Add LLInventoryListener::getSlice() and closeResult() methods that accept the int keys of result sets. getSlice() returns the requested LLSD array to its caller, while closeResult() is fire-and-forget. Because bulk data transfer is now performed by getSlice() rather than by collectDescendantsIf(), change the latter's "limit" default to unlimited. Allow the C++ code to collect an arbitrary number of LLPointer array entries, as long as getSlice() limits retrieval overhead. Spell "descendants" correctly, unlike the "descendents" spelling embedded in the rest of the viewer... sigh. Make the Lua module provide both spellings. Make MAX_ITEM_LIMIT a U32 instead of F32. In LLInventory.lua, store int result set keys from 'getItemsInfo', 'getDirectDescendants' and 'collectDescendantsIf' in a table with a close() function. The close() function invokes 'closeResult' with the bound int keys. Give that table an __index() metamethod that recognizes only 'categories' and 'items' keys: anything else returns nil. For either of the recognized keys, call 'getSlice' with the corresponding result set key to retrieve (the initial slice of) the actual result set. Cache that result. Lazy retrieval means that if the caller only cares about categories, or only about items, the other result set need never be retrieved at all. This is a first step: like the previous code, it still retrieves only up to the first 100 result set entries. But the C++ code now supports retrieval of additional slices, so extending result set retrieval is mostly Lua work. Finally, wrap the table-with-metamethod in an LL.setdtor() proxy whose destructor calls its close() method to tell LLInventoryListener to destroy the CatResultSet and ItemResultSet with the bound keys.

2024-08-29Support next(), pairs(), ipairs() for LL.setdtor() table proxies.Nat Goodspeed
Replace the global next(), pairs() and ipairs() functions with a C++ function that drills down through layers of setdtor() proxy objects and then forwards the updated arguments to the original global function. Add a Luau __iter() metamethod to setdtor() proxy objects that, like other proxy metamethods, drills down to the underlying _target object. __iter() recognizes the case of a _target table which itself has a __iter() metamethod. Also add __idiv() metamethod to support integer division. Add tests for proxy // division, next(proxy), next(proxy, key), pairs(proxy), ipairs(proxy) and 'for k, v in proxy'. Also test the case where the table wrapped in the proxy has an __iter() metamethod of its own.
2024-08-28Prevent erroneous assignment to LL.setdtor() proxy._target field.Nat Goodspeed
Trim redundant output from test_setdtor.lua.
2024-08-28Add `LL.setdtor()` function to add a "destructor" to any Lua object.Nat Goodspeed
`setdtor('description', object, function)` returns a proxy userdata object referencing object and function. When the proxy is garbage-collected, or at the end of the script, its destructor calls `function(object)`. The original object may be retrieved as `proxy._target`, e.g. to pass it to the `table` library. The proxy also has a metatable with metamethods supporting arithmetic operations, string concatenation, length and table indexing. For other operations, retrieve `proxy._target`. (But don't assign to `proxy._target`. It will appear to work, in that subsequent references to `proxy._target` will retrieve the replacement object -- however, the destructor will still call `function(original object)`.) Fix bugs in `lua_setfieldv()`, `lua_rawgetfield()` and `lua_rawsetfield()`. Add C++ functions `lua_destroyuserdata()` to explicitly destroy a `lua_emplace<T>()` userdata object, plus `lua_destroybounduserdata()`. The latter can bind such a userdata object as an upvalue to pass to `LL.atexit()`. Make `LL.help()` and `LL.leaphelp()` help text include the `LL.` prefix.

2024-08-23Look for lazy UI submodules in a require/UI subdirectory.Nat Goodspeed
This way encourages "UI = require 'UI'; UI.Floater" instead of just "Floater = require 'Floater'". Moreover, now we don't need UI to maintain a list of allowed submodules; that's effected by membership in the subdirectory.
2024-08-23Allow UI to have lazily-loaded submodules.Nat Goodspeed
Equip UI with an __index metamethod. When someone references an unknown key/field in UI, require() that module and cache it for future reference. Add util.setmetamethods() as a way to find or create a metatable on a specified table containing specified metamethods. Exercise the new functionality by referencing UI.popup in test_popup.lua.

2024-08-05Fix a couple problems with "LLPanelLogin" listener (thanks Maxim!).Nat Goodspeed
Convert plain grid (e.g. "agni") to domain form (e.g. "util.agni.lindenlab.com"). Fix a typo in `savedLogins()`: "login_list", not "login.list". login.lua now returns a table with two functions: `login.login()` and `login.savedLogins()`. Defend Lua caller against trying to engage login features too late in startup sequence: in addition to waiting for "STATE_LOGIN_WAIT", produce an error if `startup.state()` is beyond that state. Since by then `LLPanelLogin` is destroyed, `leap.request("LLPanelLogin", ...)` would get no response, causing the calling Lua script to hang until viewer shutdown.
2024-08-02Add 'LLPanelLogin' 'login', 'savedLogins' operations.Nat Goodspeed
'login' accepts optional 'username', 'slurl', 'grid'. 'savedLogins' returns the list of saved usernames in both display form and internal form. Make LLPanelLogin::getUserName() accept (const LLPointer<LLCredential>&). There's a whole separate discussion pending as to whether const LLPointer<T> should provide access to non-const T methods. Similarly, make LLCredential::getIdentifier() a const method. These two changes enable read-only access to credentials. Make LLPanelLogin methods capture and reuse LLGridManager::instance() as appropriate. Add require/login.lua and test_login.lua.
