a602f6fb7b test: index with an unclean restart after a reorg (Martin Zumsande)
01b95ac6f4 index: don't commit state in BaseIndex::Rewind (Martin Zumsande)
Pull request description:
The committed state of an index should never be ahead of the flushed chainstate.
Otherwise, in the case of an unclean shutdown, the blocks necessary to revert
from the prematurely committed state are not be available, which would corrupt the coinstatsindex in particular.
Instead, the index state will be committed with the next ChainStateFlushed notification.
Fixes#33208

3aef38f44b test: exercise index reorg assertion failure (furszy)
acf50233cd index: fix wrong assert of current_tip == m_best_block_index (Hao Xu)
Pull request description:
In BaseIndex::Sync(), pindex in `Rewind(pindex, pindex_next->pprev)` isn't always equal to m_best_block_index since m_best_block_index is updated every SYNC_LOCATOR_WRITE_INTERVAL seconds, during which multiple pindex update could happen. Thus the assert here is wrong.

Moves the file from `src/util` to `src/primitives`. Now that the
refactor is complete, Txid and Wtxid are fundamental types, so it
makes sense for them to reside in `src/primitives`.
These remaining miscellaneous changes were identified by commenting out
the `operator const uint256&` conversion and the `Compare(const uint256&)`
method from `transaction_identifier.h`.
In BaseIndex::Sync(), pindex in `Rewind(pindex, pindex_next->pprev)` isn't always
equal to m_best_block_index since m_best_block_index is updated every
SYNC_LOCATOR_WRITE_INTERVAL seconds, during which multiple pindex update could
happen. Thus the assert here is wrong.

- don't log function name
- take into account that GetName() always ends with " index"
- replace deprecated LogPrintf with LogInfo
- remove trailing \n
- adjusted log level where needed
There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).
So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.
Moved CBlockUndo disk read lookups from child index classes to
the base index class.
The goal is for child index classes to synchronize only through
events, without directly accessing the chain database.
This change will enable future parallel synchronization mechanisms,
reduce database access (when batched), and contribute toward the
goal of running indexes in a separate process (with no chain
database access).
Besides that, this commit also documents how NextSyncBlock() behaves.
It is not immediately clear this function could return the first
block after the fork point during a reorg.
Move ReadBlock code from CoinStatsIndex::CustomRewind to BaseIndex::Rewind
Move ReadUndo code from CoinStatsIndex::ReverseBlock to BaseIndex::Rewind
This commit does change behavior slightly. Since the new CustomRemove
methods only take a single block at a time instead of a range of
disconnected blocks, when they call CopyHeightIndexToHashIndex they will
now do an index seek for each removed block instead of only seeking once
to the height of the earliest removed block. Seeking instead of scanning
is a little worse for performance if there is a >1 block reorg, but
probably not noticeable unless the reorg is very deep.
We don't add or maintain these, and they are of little value, as
well as having the effect of polluting diffs.
They are also wrong, i.e DEFAULT_SCRIPTCHECK_THREADS is not in
validation.h.
This makes code more consistent and makes it easier to add compile-time checking to
enforce that format strings contain the right specifiers, because it stops
using Untranslated() to create the format string, so the Untranslated()
function will not need to get involved in formatting.

Instead of having a single NodeContext::shutdown member that is used both to
request shutdowns and check if they have been requested, use separate members
for each. Benefits of this change:
1. Should make code a little clearer and easier to search because it is easier
to see which parts of code are triggering shutdowns and which parts are just
checking to see if they were triggered.
2. Makes it possible for init.cpp to specify additional code to run when a
shutdown is requested, like signalling the m_tip_block_cv condition variable.
Motivation for this change was to remove hacky NodeContext argument and
m_tip_block_cv access from the StopRPC function, so StopRPC can just be
concerned with RPC functionality, not other node functionality.
a240e150e8 streams: remove AutoFile::Get() entirely (Pieter Wuille)
e624a9bef1 streams: cache file position within AutoFile (Pieter Wuille)
Pull request description:
Fixes#30833.
Instead of relying on frequent `ftell` calls (which appear to cause a significant slowdown on some systems) in XOR-enabled `AutoFile`s, cache the file position within `AutoFile` itself.

This ensures that the index does not miss any 'new block' signals
occurring in-between reading the 'next block' and setting 'm_synced'.
Because, if this were to happen, the ignored blocks would never be
indexed, thus stalling the index forever.
824f47294a node: Use log levels in noui_ThreadSafeMessageBox (TheCharlatan)
ddc7872c08 node: Make translations of fatal errors consistent (TheCharlatan)
Pull request description:
The extra `bilingual_str` argument of the fatal error notifications and `node::AbortNode()` is often unused and when used usually contains the same string as the message argument. It also seems to be confusing, since it is not consistently used for errors requiring user action. For example some assumeutxo fatal errors require the user to do something, but are not translated.
So simplify the fatal error and abort node interfaces by only passing a translated string. This slightly changes the fatal errors displayed to the user.

Also de-duplicate the abort error log since it is repeated in noui.cpp.
f65b0f6401 index: Move last_locator_write_time and logging to end of threadsync loop (Fabian Jahr)
Pull request description:
In the index sync thread, when initializing an index for the first time, stop callng BaseIndex::Commit when m_best_block_index is null, to avoid a spurious "failed to commit" error from that function. This error started happening in commit 7878f97bf1 from https://github.com/bitcoin/bitcoin/pull/25494 and was reported by pstratem in https://github.com/bitcoin/bitcoin/pull/26903 with an alternate fix.

Only NextSyncBlock requires cs_main lock. The
other function calls like Commit or Rewind will
lock or not cs_main internally when they need it.
Avoiding keeping cs_main locked when Commit() or
Rewind() write data to disk.
This fixes the log output when -logsourcelocations is used.
Also, instead of 'ERROR:', the log will now say '[error]', like other
errors logged with LogError.

Use SignalInterrupt object instead. There is a slight change in behavior here
because the previous StartShutdown code used to abort on failure and the
new code logs errors instead.
The legacy serialization was vulnerable to maleation and is fixed by
adopting the same serialization procedure as was already in use for
MuHash.
This also includes necessary test fixes where the hash_serialized2 was
hardcoded as well as correction of the regtest chainparams.

When using an assumedvalid chainstate, only process validationinterface
callbacks from the background chainstate within indexes. This ensures
that all indexes are built in-order.
Later, we can possibly designate indexes which can be built out of order
and continue their operation during snapshot use.
Once the background sync has completed, restart the indexes so that
they continue to index the now-validated snapshot chainstate.
