#### Summary of Changes
This PR implements the writer function for AccountMetaOptionalFields
in ByteBlockWriter::write_optional_fields().
#### Test Plan
Unit tests are included in this PR.
Tested in mnb w/ the prototype implementation of the tiered storage (#30626)
#### Summary of Changes
This PR introduces AccountMetaOptionalFields, the in-memory struct for
handling optional fields.
#### Test Plan
Unit tests are included in this PR.
Tested in mnb w/ the prototype implementation of the tiered storage (#30626).
* Makes Bank::load_program() return correct tombstones.
* Removes early TX failure caused by closed and invalid programs.
* Adjusts the feature gate of simplify_writable_program_account_check.
#### Problem
AccountMetaFlags and its fields are required to be public as the visibility of their get
functions generated by `bit_fields` are tied to the visibility of their fields, and the
get functions will later be used to support the TieredAccountMeta for AccountMeta.
#### Summary of Changes
Make AccountMetaFlags and its fields public
#### Summary of Changes
This PR adds raw_len() to ByteBlockWriter which returns
the length of the data after decoding. This information is needed
for the cold storage to keep track of the current size of the account
block after decompression.
#### Test Plan
Improved existing tests to verify the returned raw_len().
Tested in mnb w/ the prototype implementation of the tiered storage (https://github.com/solana-labs/solana/pull/30626)
`Arc` is already a reference internally, so it does not seem to be
beneficial to pass a reference to it. Just adds an extra layer of
indirection.
Functions that need to be able to increment `Arc` reference count need
to take `Arc<AtomicBool>`, but those that just want to read the
`AtomicBool` value can accept `&AtomicBool`, making them a bit more
generic.
This change focuses specifically on `Arc<AtomicBool>`. There are other
uses of `&Arc<T>` in the code base that could be converted in a similar
manner. But it would make the change even larger.
#### Summary of Changes
This PR implements AccountMetaFlags, which will later be used in
the tiered accounts storage to support optional fields.
#### Test Plan
Unit tests are included in this PR.
#### Summary of Changes
Support Lz4 in ByteBlockWriter.
#### Test Plan
Added test cases for Lz4.
Tested in mnb w/ the prototype implementation of the tiered storage (#30626)
The callstack updated in this PR passed an &Arc<...> down only to have
the bottom level clone the reference. Thus, we are giving shared
ownership so the reference is a bit redundant and arguably obscures the
intention to clone further down the callstack.
#### Summary of Changes
This PR includes the util structs for writing byte blocks, which will be used
by the TieredStorage writer (currently used in the prototype #30626).
The PR only includes the Raw encoding format. Will add more in subsequent PRs.
#### Test Plan
Tested in mnb with the prototype implementation of the tiered-storage (#30626)
Unit tests are also included in this PR.
#### Problem
AppendVec currently uses std::io::ErrorKind::Other for its own errors.
#### Summary of Changes
This PR introduces AppendVecError and has AppendVec use it.
#### Problem
The return error type -- io::Error used in reconstruct_single_storage()
isn't suitable to describe all possible errors inside the function such as
AccountsFileError.
#### Summary of Changes
This PR makes it return SnapshotError which can better handle
both AccountsFileError and io::Error.
#### Problem
Part of the snapshot-related code uses io::Error while other parts use SnapshotError.
#### Summary of Changes
As SnapshotError can be created from io::Error, this PR makes snapshot-related
code to use SnapshotError instead.
#### Problem
AccountsFile- and AppendVec-related code uses io::Error for their main error type. However, there're many errors under AccountsFile that don't belong to io::Error.
#### Summary of Changes
This PR introduces AccountsFileError and makes minimum changes to keep the PR small.
Subsequent changes related to this will be in separate PRs.

Counters can only report a single field; this adds an extra step to
debugging efforts to figure out the context for where/why the counted
event occurred. Use datapoints instead to subtmit some extra context.

This reverts commit 1ed9b3b2c8e84689a918beee7159f63c56500a96.
Within the contents of snapshot_utils::add_bank_snapshot(), metrics were
being reported in several datapoints and counters. This adds extra
overhead, and makes it harder to correlate fields that correspond to the
same snapshot.
So, combine the counters and multiple datapoints into a single
datapoint.
* Make load_program method of Bank public for use in ledger-tool
* Add an accessor method to get a reference to builtin_programs of Bank
* Add a parameter to Bank::load_program to control debugging_features
* AccountSharedData: make data_mut() private
This ensures that the inner Vec is never handed out. This is in
preparation of enforcing that the capacity of the inner vec never
shrinks, which is required for direct mapping.
* Adds the feature bpf_account_data_direct_mapping.
* Remaps EbpfError::AccessViolation into InstructionError::ReadonlyDataModified.
* WIP: Memory regions for each instruction account in create_vm().
* Fix serialization benches, run both copy and !copy variants
* rbpf-cli: fix build
* BorrowedAccount: ensure that account capacity is never reduced
Accounts can be directly mapped in address space. Their capacity can't
be reduced mid transaction as that would create holes in vm address
space that point to invalid host memory.
* bpf_load: run serialization tests for both copy and !copy account data
* bpf_loader: add Serializer::write_account
* fix lints
* BorrowedAccount: make_data_mut is host only
* Fix unused import warning
* Fix lints
* cpi: add explicit direct_mapping arg to update_(callee|caller)_account
* cpi: rename account_data_or_only_realloc_padding to serialized_data
* cpi: add CallerAccount::original_data_len comment
* cpi: add update_callee_account direct_mapping test
* cpi: add test_update_caller_account_data_direct_mapping and fix bug
We used to have a bug in zeroing data when shrinking account, where we zeroed
the spare account capacity but not the realloc padding.
* cpi: add tests for mutated readonly accounts
* cpi: update_caller_account doesn't need to change .serialized_data when direct_mapping is on
* cpi: update_caller_account: ensure that account capacity is always enough
Introduce a better way to ensure that account capacity never goes below what
might be mapped in memory regions.
* cpi: zero account capacity using the newly introduced BorrowedAccount::spare_data_capacity_mut()
Before we were using BorrowedAccount::get_data_mut() to get the base pointer to
the account data, then we were slicing the spare capacity from it. Calling
get_data_mut() doesn't work if an account has been closed tho, since the
current program doesn't own the account anymore and therefore get_data_mut()
errors out.
* bpf_loader: fix same lint for the umpteenth time
* bpf_loader: map AccessViolation to ReadonlyDataModified only for account region violations
* programs/sbf: realloc: add test for large write after realloc
Add a test that after a realloc does a large write that spans the
original account length and the realloc area. This ensures that memory
mapping works correctly across the boundary.
* programs/sbf: run test_program_sbf_realloc with both direct_mapping on and off
By default test banks test with all features on. This ensures we keep
testing the existing code until the new feature is enabled.
* bpf_loader: tweak memcmp syscall
Split the actual memcmp code in a separate function. Remove check
indexing the slices since the slices are guaranteed to have the correct
length by construction.
* bpf_loader: tweak the memset syscall
Use slice::fill, which is effectively memset.
* bpf_loader: syscalls: update mem syscalls to work with non contiguous memory
With direct mapping enabled, accounts can now span multiple memory
regions.
* fix lint, rebase mem_ops
* Implement CoW for writable accounts
* Fix CI
* Move CoW to the MemoryMapping level
* Update after rbpf API change
* Fix merge screwup
* Add create_vm macro. Fix benches.
* cpi: simplify update_caller_account
Simplify the logic to update a caller's memory region when a callee
causes an account data pointer to change (eg during CoW)
* benches/bpf_loader: move serialization out of create_vm bench
* benches/bpf_loader: don't copy accounts when direct mapping is on
* Fix review nits
* bpf_loader: mem_ops: handle u64 overflow in MemoryChunkIterator::new
When starting at u64::MAX, the chunk iterator would always return the
empty sequence (None on the first next()) call, instead of returning a
memory access violation.
Use checked instead of saturating arithmetic to detect the condition and
error out.
This commit also adds more tests around boundary conditions.
* Fix loader-v3 tests: data_mut => data_as_mut_slice
* Fix CI
* bpf_loader: fix tuner bench: account must be writable
With direct mapping on, invalid writes are caught early meaning the
tuner would fail on the first store and not consume the whole budget
like the benchmark expects.
