* YT-21233: Rewrite ConvertTo CPO using TagInvokearkady-e1ppa2024-11-085-0/+299
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Plan: 1) Remove `IAttributedDictionary` type from the public API. \+ 2) Remove `Set` method from public API in favor of `operator<<=`. \+ 3) Adopt `ConvertTo<T>` (or other name) CPO with proper extension into `NYT::NYson::ConvertTo` from `yt/core`. 4) Use CPO from (3) to eliminate direct dependency on `yt/core` of `Get/Find` methods from attributes API. 5) Adopt `ConvertToYsonString` (or other name) CPO with proper extension into `yt/core` customisations. 6) Use CPO from (5) to eliminate direct dependency on `yt/core` of `TErrorAttribute` ctor. 7) Swap attributes implementation to the one which doesn’t use `IAttributeDictionary`. 8) At this point `stripped_error*` can be moved to library/cpp/yt and so can recursively dependant on THROW macro methods `Get/Find/…`. 9) Adjust CPO’s to work with `std::string` instead of `TYsonString` assuming text format to be used (maybe `TString` for now). 10) Remove dep of `library/cpp/yt/error` on `yson` entirely. This pr addresses 3-4 steps of plan. Below is a brief explanation of design decisions. We want to have a concept which detects if there is a `ConvertTo` method and if true, try calling it. Templates can only perform unqualified name lookup and if we allow non-ADL overloads to be found, we would have dependency on inclusion order (if `ConvertTo` is included prior to our code, everything works fine, but if the order is reverse, templated dispatch would fail, but direct call would work just fine). That is why we adopt niebloids which first disable ADL lookup of the name `ConvertTo` by directing it to niebloid implemented via `TagInvoke` mechanism. TagInvoke design <https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1895r0.pdf> . TL;DR: we want to have behavior which is consistent with inclusion order. Key difference now is that `ConvertTo` works consistently in both manual calls and template function body calls and is no longer visible for ADL part of the unqualified name lookup commit_hash:32af641bd0af559bfe670c2ceb36721fb4afc2dd

* YT-20614: Change cross-cell copy format (in preparation for Sequoia)h0pless2024-07-081-0/+17
| | | | | | | | | | | | The new format is better optimized for VectorizedRead, which is needed in Sequoia. Previously, the output for the BeginCopy verb was a serialized subtree plus the list of opaque children. In a non-Sequoia world, that is useful and easy to work with. However, in Sequoia, a subtree might not be contained on the same cell, which makes it difficult to use the old data transfer format. Now it's a vector of nodes with clear separation between them. This change makes it easier to work with VectorizedRead since the conversion between BeginCopy return and VectorizedRead(BeginCopy) return is very straight-forward. Additionally, this change helps with copying from Cypress to Sequoia, since now it's much easier to process each node individually (which is needed for Sequoia to work and not clog up one cell). In the next PR, I'm planning on: 1. Making BeginCopy a read-request (removing snapshot locks). So the verb will only return meta-information about the requested nodes. 2. Adding a verb, executed before BeginCopy, where the locks would be taken and the general structure of the tree is returned. 017ec9971e8e0a611a7286ed748b6071cfc89048

* YT-21868: Refactor NYT::Formatarkady-e1ppa2024-06-071-0/+2
| | | | | | | | | | | | | | | | | | | | NYT::Format had several problems: 1. There are too many ways to enable printing of T. Not all are equally good. You could specialize TValueFormatter, you could write an overload of FormatValue, you could write an overload of ToString, you could write an overload of operator << for special stream or you could specialize the Out function. 2. If you attempt to print T which cannot be printed, you get a linker error without a proper source location which is very frustrating to work with. 3. There is no static analysis of format string performed even when it is possible. 4. If you write FormatValue overload, you still have to write ToString overload if you want to use this function (and people tend to use it quite a bit, since it is defined for util types and enums. This pr addresses these issues to some extent. Relevant changes: 1. The only way to support NYT::Format is to define the FormatValue overload. Otherwise, you get a compile-time error. 2. Format overloads have changed: Now you have two options for general use: ``` TString Format(TStaticFormat<TArgs...> fmt, TArgs&&... args); TString Format(TRuntimeFormat fmt, TArgs&&... args); ``` Either overload checks if TArg has a FormatValue overload. TStaticFormat performs a compile-time check of flags and the argument count. It binds to any string literal and constexpr string/string_view (and TStringBuf). TRuntimeFormat has to be mentioned explicitly. Otherwise, you will get a compile-time error for using runtime variable as a format. 3(!!!). Types which name begins with NYT:: have a specialization of ToString function which uses FormatValue. Thus, if you write class in namespace NYT and define FormatValue, you get ToString automatically. If your type is not from namespace enclosing NYT, you can just call NYT::ToString for the same effect. This limitation was caused by the fact, that we cannot review all of the external projects code which might inherit from stl classes or adopt some other questionable code practises which may completely break the dispatching mechanism of ToString due to the specialization (there were such cases). Proper documentation of this library will be added soon, so that this interaction is made known. This limitation might be lifted later 77beb68082e10aaf48be1842aad8aba63f26c1bd
