The actual tasks are quite different - In normal mode, preparations for saving a new block are made, which is then saved: find the correct position on disk (maybe skipping to a new blk file), check for available disk space, update the blockfile info db, save the block. - during reindex, most of this is not necessary (the block is already on disk after all), only the blockfile info needs to rebuilt because reindex wiped the leveldb it's saved in. Using one function with many conditional statements for this leads to code that is hard to read / understand and bug-prone: - many code paths in `FindBlockPos` are conditional on `fKnown` or `!fKnown` - It's not really clear what actually needs to be done during reindex (we don't need to "save a block to disk" or "find a block pos" as the function names suggest) - logic that should be applied to only one of the two modes is sometimes applied to both (see first commit, or #27039) #24858 and #27039 were recent bugs directly related to the differences between reindexing and normal mode, and in both cases the simple fix took a long time to be reviewed and merged. This PR proposes to clean this code up by splitting out the reindex logic into a separate function (`UpdateBlockInfo`) which will be called directly from validation. As a result, `SaveBlockToDisk` and `FindBlockPos` only need to cover the non-reindex logic.

This introduces compliance issues with more strict clients. There are the major misbehaviors that I found: - returning non-200 HTTP codes for RPC errors like "Method not found" (this is not a server error or an HTTP error) - returning both `"error"` and `"result"` fields together in a response object. - different error-handling behavior for single and batched RPC requests (batches contain errors in the response but single requests will actually throw HTTP errors) https://github.com/bitcoin/bitcoin/pull/15495 added regression tests after a discussion in https://github.com/bitcoin/bitcoin/pull/15381 to kinda lock in our RPC behavior to preserve backwards compatibility. https://github.com/bitcoin/bitcoin/pull/12435 was an attempt to allow strict 2.0 compliance behind a flag, but was abandoned. The approach in this PR is not strict and preserves backwards compatibility in a familiar bitcoin-y way: all old behavior is preserved, but new rules are applied to clients that opt in. One of the rules in the [JSON RPC 2.0 spec](https://www.jsonrpc.org/specification#request_object) is that the kv pair `"jsonrpc": "2.0"` must be present in the request. Well, let's just use that to trigger strict 2.0 behavior! When that kv pair is included in a request object, the [response will adhere to strict JSON-RPC 2.0 rules](https://www.jsonrpc.org/specification#response_object), essentially: - always return HTTP 200 "OK" unless there really is a server error or malformed request - either return `"error"` OR `"result"` but never both - same behavior for single and batch requests If this is merged next steps can be: - Refactor bitcoin-cli to always use strict 2.0 - Refactor the python test framework to always use strict 2.0 for everything - Begin deprecation process for 1.0/1.1 behavior (?) If we can one day remove the old 1.0/1.1 behavior we can clean up the rpc code quite a bit.

For example, it is not possible to set a parameter controlling the transaction format and a parameter controlling the address format at the same time because one parameter will override the other. This limitation is inconvenient for multiprocess code since it is not possible to create just one type of stream and serialize any object to it. Instead it is necessary to create different streams for different object types, which requires extra boilerplate and makes using the new parameter fields a lot more awkward than the older version and type fields. Fix this problem by allowing an unlimited number of serialization stream parameters to be set, and allowing them to be requested by type. Later parameters will still override earlier parameters, but only if they have the same type. For an example of different ways multiple parameters can be set, see the new [`with_params_multi`](https://github.com/bitcoin/bitcoin/blob/40f505583f4edeb2859aeb70da20c6374d331a4f/src/test/serialize_tests.cpp#L394-L410) unit test. This change requires replacing the `stream.GetParams()` method with a `stream.GetParams<T>()` method in order for serialization code to retrieve the desired parameters. The change is more verbose, but probably a good thing for readability because previously it could be difficult to know what type the `GetParams()` method would return, and now it is more obvious. --- This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/issues/28722).

Currently the main map in `TxOrphanage` is indexed by txid; we do not allow 2 transactions with the same txid into TxOrphanage. This means that if we receive a transaction and want to store it in orphanage, we'll fail to do so if a same-txid-different-witness version of the tx already exists in the orphanage. The existing orphanage entry can stay until it expires 20 minutes later, or until we find that it is invalid. This means an attacker can try to block/delay us accepting an orphan transaction by sending a mutated version of the child ahead of time. See included test. Prior to #28970, we don't rely on the orphanage for anything and it would be relatively difficult to guess what transaction will go to a node's orphanage. After the parent(s) are accepted, if anybody sends us the correct transaction, we'll end up accepting it. However, this is a bit more painful for 1p1c: it's easier for an attacker to tell when a tx is going to hit a node's orphanage, and we need to store the correct orphan + receive the parent before we'll consider the package. If we start out with a bad orphan, we can't evict it until we receive the parent + try the 1p1c, and then we'll need to download the real child, put it in orphanage, download the parent again, and then retry 1p1c.

Index by wtxid instead of txid to allow entries with the same txid but different witnesses in orphanage. This prevents an attacker from blocking a transaction from entering the orphanage by sending a mutated version of it.

58594c7040241f2312b0b8735a8baf0412674613 fuzz: txorphan tests fixups (Sergi Delgado Segura) Pull request description: Motivated by https://github.com/bitcoin/bitcoin/pull/28970#discussion_r1576401327 Adds the following fixups in txorphan fuzz tests: - Don't bond the output count of the created orphans to the number of available coins - Allow duplicate inputs but don't store duplicate outpoints Most significantly, this gets rid of the `duplicate_input` flag altogether, making the test easier to reason about. Notice how, under normal conditions, duplicate inputs would be caught by `MemPoolAccept::PreChecks`, however, no validations checks are run on the test before adding data to the orphanage (neither were they before this patch) ## Rationale The way the test is currently written, duplicate inputs are allowed based on a random flag (`duplicate_input`). If the flag is unset, upon selecting an outpoint as input for a new transaction, the input is popped to prevent re-selection and later re-added to the collection (once all inputs have been picked). However, the re-addition to the collection is performed independently of whether the flag was set or not. This means that, if the flag is set, the selected inputs are duplicated which in turn makes these inputs more likely to be re-picked in the following iteration of the loop. Additionally, both the input and output count of the transaction are bonded to the number of available outpoints. This makes sense for the former, but the latter shouldn't be.

Since C++20, we can force them to evaluate at compile time, turning all the miniscript type constants into actual compile-time constants.

Since network-adjusted time is now only used for warning/informational purposes, cleaning up the logic (building on @dergoegge's approach in #28956) should be quite straightforward and uncontroversial. The main changes are: - Previously, we would only calculate the time offset from the first 199 outbound peers that we connected to. This limitation is now removed, and we have a proper rolling calculation. I've reduced the set to 50 outbound peers, which seems plenty. - Previously, we would automatically use the network-adjusted time if the difference was < 70 mins, and warn the user if the difference was larger than that. Since there is no longer any automated time adjustment, I've changed the warning threshold to ~~20~~ 10 minutes (which is an arbitrary number). - Previously, a warning would only be raised once, and then never again until node restart. This behaviour is now updated to 1) warn to log for every new outbound peer for as long as we appear out of sync, 2) have the RPC warning toggled on/off whenever we go in/out of sync, and 3) have the GUI warn whenever we are out of sync (again), but limited to 1 messagebox per 60 minutes - no more globals - remove the `-maxtimeadjustment` startup arg Closes #4521 ACKs for top commit: sr-gi: Re-ACK [c6be144](https://github.com/bitcoin/bitcoin/pull/29623/commits/c6be144c4b774a03a8bcab5a165768cf81e9b06b) achow101: reACK c6be144c4b774a03a8bcab5a165768cf81e9b06b dergoegge: utACK c6be144c4b774a03a8bcab5a165768cf81e9b06b Tree-SHA512: 1063d639542e882186cdcea67d225ad1f97847f44253621a8c4b36c4d777e8f5cb0efe86bc279f01e819d33056ae4364c3300cc7400c087fb16c3f39b3e16b96

See https://github.com/bitcoin/bitcoin/issues/27463 for overall package relay tracking. Rationale: This is "non-robust 1-parent-1-child package relay" which is immediately useful. - Relaying 1-parent-1-child CPFP when mempool min feerate is high would be a subset of all package relay use cases, but a pretty significant improvement over what we have today, where such transactions don't propagate at all. [1] - Today, a miner can run this with a normal/small maxmempool to get revenue from 1p1c CPFP'd transactions without losing out on the ones with parents below mempool minimum feerate. - The majority of this code is useful for building more featureful/robust package relay e.g. see the code in #27742. The first 2 commits are followups from #29619: - https://github.com/bitcoin/bitcoin/pull/29619#discussion_r1523094034 - https://github.com/bitcoin/bitcoin/pull/29619#discussion_r1519819257 Q: What makes this short of a more full package relay feature? (1) it only supports packages in which 1 of the parents needs to be CPFP'd by the child. That includes 1-parent-1-child packages and situations in which the other parents already pay for themselves (and are thus in mempool already when the package is submitted). More general package relay is a future improvement that requires more engineering in mempool and validation - see #27463. (2) We rely on having kept the child in orphanage, and don't make any attempt to protect it while we wait to receive the parent. If we are experiencing a lot of orphanage churn (e.g. an adversary is purposefully sending us a lot of transactions with missing inputs), we will fail to submit packages. This limitation has been around for 12+ years, see #27742 which adds a token bucket scheme for protecting package-related orphans at a limited rate per peer. (3) Our orphan-handling logic is somewhat opportunistic; we don't make much effort to resolve an orphan beyond asking the child's sender for the parents. This means we may miss packages if the first sender fails to give us the parent (intentionally or unintentionally). To make this more robust, we need receiver-side logic to retry orphan resolution with multiple peers. This is also an existing problem which has a proposed solution in #28031.

Especially in RPCs with a large number of parameters, this can be quite helpful. Example usage: ```cpp const auto action{self.Arg<std::string>("action")}; ``` Most of the LoC is adding test coverage and documentation updates. No behaviour change. An alternative approach to #27788 with significantly less overhaul.

It's very hard to randomly construct a transaction that would be the parent of an existing orphanage tx. For functions like AddChildrenToWorkSet and GetChildren that take orphan parents, use a tx that was previously constructed.

2024-04-25refactor: Drop util::Result operator=Ryan Ofsky
`util::Result` objects are aggregates that can hold multiple fields with different information. Currently Result objects can only hold a success value of an arbitrary type or a single bilingual_str error message. In followup PR https://github.com/bitcoin/bitcoin/pull/25722, Result objects may be able to hold both success and failure values of different types, plus error and warning messages. Having a Result::operator= assignment operator that completely erases all existing Result information before assigning new information is potentially dangerous in this case. For example, code that looks like it is assigning a warning value could erase previously-assigned success or failure values. Conversely, code that looks like it is just assigning a success or failure value could erase previously assigned error and warning messages. To prevent potential bugs like this, disable Result::operator= assignment operator. It is possible in the future we may want to re-enable operator= in limited cases (such as when implicit conversions are not used) or add a Replace() or Reset() method that mimicks default operator= behavior. Followup PR https://github.com/bitcoin/bitcoin/pull/25722 also adds a Result::Update() method providing another way to update an existing Result object.

Libevent shows many of the same symptoms, few maintainers and slow releases. While libevent can not be removed completely over night we should start removing it’s usage where it's possible, ideally with the end goal to removing it completely. This is a pretty easy win in that direction. The [`evhttp_uridecode` function from libevent](https://github.com/libevent/libevent/blob/e0a4574ba2cbcdb64bb2b593e72be7f7f4010746/http.c#L3542) we were using in `urlDecode` could be easily emulated in fewer LOC. This also ports the [applicable test vectors over from libevent](https://github.com/libevent/libevent/blob/master/test/regress_http.c#L3430).

2024-04-24common: Don't terminate on null character in UrlDecodeFabian Jahr
The previous behavior was the result of casting the result returned from the libevent function evhttp_uridecode to std:string but this was probably not intended.
