If a linked chunk update starts with a RemoveChunk update, then the
transaction may start with a SELECT query and be considered a read
transaction. Soon enough, it will be upgraded into a write transaction,
because of the next UPDATE/DELETE operations that happen thereafter. If
there's another write transaction already happening, this may result in
a SQLITE_BUSY error, according to
https://www.sqlite.org/lang_transaction.html#deferred_immediate_and_exclusive_transactions
One solution is to always start the transaction in immediate mode. This
may also fail with SQLITE_BUSY according to the documentation, but it's
unclear whether it will happen in general, since we're using WAL mode
too. Let's try it out.
This patch fixes an edge case where the member is alone in the room with
a service member. We already subtracted the number of service members
in the case we calculated the room summary ourselves, but we did not do
so when the server provided the room summary.
This lead to the room, instead of being called `Empty`, being called
`Foo and N others`.
Update the workaround for https://github.com/rust-lang/rust/issues/109717 to
avoid hardcoding the clang version; instead, run `clang -dumpversion` to figure
it out.
While we're there, use the `CC_x86_64-linux-android` env var, which should
point to clang, rather than relying on `ANDROID_NDK_HOME` to be set.
The `MemoryStore` implementation of the `StateStore` has grown into a
monster, with one lock per field. It's probably overkill, as individual
fields don't need fine-grained locks like this; after all, accesses to
the store shouldn't be reentrant in general.
Fixes#3720.
- rename RawLinkedChunk -> RawChunk
- rename RawChunk::id -> RawChunk::identifier
- precise that a `RawChunk` is mostly a `Chunk` with different
previous/next links.
And let the caller rebuild the linked chunk. This is slightly nicer in
that it allows us to display the raw representation of a reloaded linked
chunk, before checking its internal state is consistent; this will allow
for better debug of issues related to the linked chunk internal state.
No functional changes.
The `MediaFormat` reflects only the request that would be made to the homeserver.
There is no link between the format of the files stored in the media cache and their purpose in an event.
`MediaFormat::Tumbnail` means that we request a server-generated thumbnail of a file in the media repository.
Since the thumbnail is its own file in the media repository, it makes more sense to use `MediaFormat::File`.

By default, the event cache store will be disabled. If disabled, it will
clean all the events in the cache store; most of the time this will do
nothing, since the store will not even be filled with any event data, so
it would be cheap to do. If some data was filled in the cache store
before, then it would be cleared after the cache store has been
disabled.
This makes a less awkward API than the previous one, where `None` and
`Some(false)` carried different semantics.
This patch creates `ObservableItemsTransactionEntry` that mimics
`ObservableVectorTransactionEntry`. The differences are `set` is
renamed `replace`, and `remove` is unsafe (because I failed to update
`AllRemoteEvents` in this method due to the borrow checker).
