Instead, there is a single Cast opcode, that takes the affinity as a parameter. Currently we just call a function when we need to cast. This PR fixes the compat file, implements the cast opcode, and in at least one instance, when explicitly using the CAST keyword, uses that opcode instead of a function in the generated bytecode. --- COMPAT.md | 6 +----- core/translate/expr.rs | 25 ++++++------------------- core/vdbe/execute.rs | 25 +++++++++++++++++++++++++ core/vdbe/explain.rs | 9 +++++++++ core/vdbe/insn.rs | 7 +++++++ 5 files changed, 48 insertions(+), 24 deletions(-) diff --git a/COMPAT.md b/COMPAT.md index a436e80ef..2cd183ced 100644 --- a/COMPAT.md +++ b/COMPAT.md @@ -427,6 +427,7 @@ Modifiers: | BitOr | Yes | | | Blob | Yes | | | BeginSubrtn | Yes | | +| Cast | Yes | | | Checkpoint | Yes | | | Clear | No | | | Close | Yes | | @@ -554,11 +555,6 @@ Modifiers: | String8 | Yes | | | Subtract | Yes | | | TableLock | No | | -| ToBlob | No | | -| ToInt | No | | -| ToNumeric | No | | -| ToReal | No | | -| ToText | No | | | Trace | No | | | Transaction | Yes | | | VBegin | No | | diff --git a/core/translate/expr.rs b/core/translate/expr.rs index 2d7cdc26b..59cd4945a 100644 --- a/core/translate/expr.rs +++ b/core/translate/expr.rs @@ -8,7 +8,7 @@ use super::plan::TableReferences;

Wait for commit dependencies, which we don't even track yet... + ** Excerpt from what's a commit dependency and how it's tracked in the original paper: + ** """ + A transaction T1 has a commit dependency on another transaction + T2, if T1 is allowed to commit only if T2 commits. If T2 aborts, + T1 must also abort, so cascading aborts are possible. T1 acquires a + commit dependency either by speculatively reading or speculatively ignoring a version, + instead of waiting for T2 to commit. + We implement commit dependencies by a register-and-report + approach: T1 registers its dependency with T2 and T2 informs T1 + when it has committed or aborted. Each transaction T contains a + counter, CommitDepCounter, that counts how many unresolved + commit dependencies it still has. A transaction cannot commit + until this counter is zero. In addition, T has a Boolean variable + AbortNow that other transactions can set to tell T to abort. Each + transaction T also has a set, CommitDepSet, that stores transaction IDs + of the transactions that depend on T. + To take a commit dependency on a transaction T2, T1 increments + its CommitDepCounter and adds its transaction ID to T2’s CommitDepSet. + When T2 has committed, it locates each transaction in + its CommitDepSet and decrements their CommitDepCounter. If + T2 aborted, it tells the dependent transactions to also abort by + setting their AbortNow flags. If a dependent transaction is not + found, this means that it has already aborted. + Note that a transaction with commit dependencies may not have to + wait at all - the dependencies may have been resolved before it is + ready to commit. Commit dependencies consolidate all waits into + a single wait and postpone the wait to just before commit. + Some transactions may have to wait before commit. + Waiting raises a concern of deadlocks. + However, deadlocks cannot occur because an older transaction never + waits on a younger transaction. In + a wait-for graph the direction of edges would always be from a + younger transaction (higher end timestamp) to an older transaction + (lower end timestamp) so cycles are impossible. + """ + ** If you're wondering when a speculative read happens, here you go: + ** Case 1: speculative read of TB: + """ + If transaction TB is in the Preparing state, it has acquired an end + timestamp TS which will be V’s begin timestamp if TB commits. + A safe approach in this situation would be to have transaction T + wait until transaction TB commits. However, we want to avoid all + blocking during normal processing so instead we continue with + the visibility test and, if the test returns true, allow T to + speculatively read V. Transaction T acquires a commit dependency on + TB, restricting the serialization order of the two transactions. That + is, T is allowed to commit only if TB commits. + """ + ** Case 2: speculative ignore of TE: + """ + If TE’s state is Preparing, it has an end timestamp TS that will become + the end timestamp of V if TE does commit. If TS is greater than the read + time RT, it is obvious that V will be visible if TE commits. If TE + aborts, V will still be visible, because any transaction that updates + V after TE has aborted will obtain an end timestamp greater than + TS. If TS is less than RT, we have a more complicated situation: + if TE commits, V will not be visible to T but if TE aborts, it will + be visible. We could handle this by forcing T to wait until TE + commits or aborts but we want to avoid all blocking during normal processing. + Instead we allow T to speculatively ignore V and + proceed with its processing.

If T2 aborts, - T1 must also abort, so cascading aborts are possible. T1 acquires a - commit dependency either by speculatively reading or speculatively ignoring a version, - instead of waiting for T2 to commit. - We implement commit dependencies by a register-and-report - approach: T1 registers its dependency with T2 and T2 informs T1 - when it has committed or aborted. Each transaction T contains a - counter, CommitDepCounter, that counts how many unresolved - commit dependencies it still has. A transaction cannot commit - until this counter is zero. In addition, T has a Boolean variable - AbortNow that other transactions can set to tell T to abort. Each - transaction T also has a set, CommitDepSet, that stores transaction IDs - of the transactions that depend on T. - To take a commit dependency on a transaction T2, T1 increments - its CommitDepCounter and adds its transaction ID to T2’s CommitDepSet. - When T2 has committed, it locates each transaction in - its CommitDepSet and decrements their CommitDepCounter. If - T2 aborted, it tells the dependent transactions to also abort by - setting their AbortNow flags. If a dependent transaction is not - found, this means that it has already aborted. - Note that a transaction with commit dependencies may not have to - wait at all - the dependencies may have been resolved before it is - ready to commit. Commit dependencies consolidate all waits into - a single wait and postpone the wait to just before commit. - Some transactions may have to wait before commit. - Waiting raises a concern of deadlocks. - However, deadlocks cannot occur because an older transaction never - waits on a younger transaction. In - a wait-for graph the direction of edges would always be from a - younger transaction (higher end timestamp) to an older transaction - (lower end timestamp) so cycles are impossible. - """ - ** If you're wondering when a speculative read happens, here you go: - ** Case 1: speculative read of TB: - """ - If transaction TB is in the Preparing state, it has acquired an end - timestamp TS which will be V’s begin timestamp if TB commits. - A safe approach in this situation would be to have transaction T - wait until transaction TB commits. However, we want to avoid all - blocking during normal processing so instead we continue with - the visibility test and, if the test returns true, allow T to - speculatively read V. Transaction T acquires a commit dependency on - TB, restricting the serialization order of the two transactions. That - is, T is allowed to commit only if TB commits. - """ - ** Case 2: speculative ignore of TE: - """ - If TE’s state is Preparing, it has an end timestamp TS that will become - the end timestamp of V if TE does commit. If TS is greater than the read - time RT, it is obvious that V will be visible if TE commits. If TE - aborts, V will still be visible, because any transaction that updates - V after TE has aborted will obtain an end timestamp greater than - TS. If TS is less than RT, we have a more complicated situation: - if TE commits, V will not be visible to T but if TE aborts, it will - be visible. We could handle this by forcing T to wait until TE - commits or aborts but we want to avoid all blocking during normal processing. - Instead we allow T to speculatively ignore V and - proceed with its processing.

There are two points that must be highlighted: 1. There is a `StateTransition` trait implemented like: ```rust pub trait StateTransition { type State; type Context; fn transition<'a>(&mut self, context: &Self::Context) -> Result; fn finalize<'a>(&mut self, context: &Self::Context) -> Result<()>; fn is_finalized(&self) -> bool; } ``` where there exists `transition` which tries to move state forward, and `finalize` which marks the state machine as "finalized" so that **no other call to finalize will forward the state and it will panic instead. 2. Before, we would store the state of a state machine inside the callee's struct, but I'm proposing we do something different where the callee will return the state machine and the caller will be responsible of advancing it. This way we don't need to track many reset operations in case of failures or rollbacks, and instead we could simply drop a state machine and all other nested state machines will drop in a cascade. ---
