2023-10-23bcachefs: Add iter_flags arg to bch2_btree_delete_range()Kent Overstreet1-5/+7
Will be used by the new snapshot tests, to pass in BTREE_ITER_ALL_SNAPSHOTS. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: bch2_trans_update() is now __must_checkKent Overstreet1-2/+2
With snapshots, bch2_trans_update() has to check if we need a whitout, which can cause a transaction restart, so this is important now. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Fix unit & perf tests for snapshotsKent Overstreet1-29/+32
This finishes updating the unit & perf tests for snapshots - btrees that use snapshots now always require the snapshot field of the start position to be a valid snapshot ID. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: btree_pathKent Overstreet1-92/+97
This splits btree_iter into two components: btree_iter is now the externally visible componont, and it points to a btree_path which is now reference counted. This means we no longer have to clone iterators up front if they might be mutated - btree_path can be shared by multiple iterators, and cloned if an iterator would mutate a shared btree_path. This will help us use iterators more efficiently, as well as slimming down the main long lived state in btree_trans, and significantly cleans up the logic for iterator lifetimes.

2023-10-23bcachefs: Fix 32 bit build failuresBrett Holman1-4/+4
This fix replaces multiple 64 bit divisions with do_div() equivalents. Signed-off-by: Brett Holman <bholman.devel@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Fixes for unit testsKent Overstreet1-7/+11
The unit tests hadn't been updated for various recent btree changes - this patch makes them work again. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Improve iter->should_be_lockedKent Overstreet1-8/+8
Adding iter->should_be_locked introduced a regression where it ended up not being set on the iterator passed to bch2_btree_update_start(), which is definitely not what we want. This patch requires it to be set when calling bch2_trans_update(), and adds various fixups to make that happen. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Kill __btree_delete_at()Kent Overstreet1-3/+6
With trans->updates2 gone, we can now drop this helper and use bch2_btree_delete_at() instead. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Check for errors from bch2_trans_update()Kent Overstreet1-1/+1
Upcoming refactoring is going to change bch2_trans_update() to start returning transaction restarts. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Add a perf test for multiple updates per commitKent Overstreet1-0/+37

2023-10-23bcachefs: Start using bpos.snapshot fieldKent Overstreet1-0/+1
This patch starts treating the bpos.snapshot field like part of the key in the btree code: * bpos_successor() and bpos_predecessor() now include the snapshot field * Keys in btrees that will be using snapshots (extents, inodes, dirents and xattrs) now always have their snapshot field set to U32_MAX The btree iterator code gets a new flag, BTREE_ITER_ALL_SNAPSHOTS, that determines whether we're iterating over keys in all snapshots or not - internally, this controlls whether bkey_(successor|predecessor) increment/decrement the snapshot field, or only the higher bits of the key. We add a new member to struct btree_iter, iter->snapshot: when BTREE_ITER_ALL_SNAPSHOTS is not set, iter->pos.snapshot should always equal iter->snapshot, which will be 0 for btrees that don't use snapshots, and alsways U32_MAX for btrees that will use snapshots (until we enable snapshot creation). This patch also introduces a new metadata version number, and compat code for reading from/writing to older versions - this isn't a forced upgrade (yet).

2023-10-23bcachefs: Require all btree iterators to be freedKent Overstreet1-6/+22
We keep running into occasional bugs with btree transaction iterators overflowing - this will make those bugs more visible. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Rename BTREE_ID enums for consistency with other enumsKent Overstreet1-25/+25

2023-10-23bcachefs: Fix rand_delete() testKent Overstreet1-4/+3
When we didn't find a key to delete we were getting a null ptr deref. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add error handling to unit & perf testsKent Overstreet1-84/+165
This way, these tests can be used with tests that inject IO errors and shut down the filesystem. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Some btree iterator improvementsKent Overstreet1-19/+27

2023-10-23bcachefs: Kill TRANS_RESET_MEM|TRANS_RESET_ITERSKent Overstreet1-17/+56
All iterators should be released now with bch2_trans_iter_put(), so TRANS_RESET_ITERS shouldn't be needed anymore, and TRANS_RESET_MEM is always used. Also convert more code to __bch2_trans_do().

2023-10-23bcachefs: Split out btree_trigger_flagsKent Overstreet1-5/+5
The trigger flags really belong with individual btree_insert_entries, not the transaction commit flags - this splits out those flags and unifies them with the BCH_BUCKET_MARK flags. Todo - split out btree_trigger.c from buckets.c Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
