2011-09-14tdb2: catch errors in tdb1_needs_recovery()Rusty Russell1-1/+1
The tdb1 backend simply returns "true" if there's an error determining if a tdb needs recovery. But this leads failtest down a rabbit hole; it's better to return the error at this case (and makes for better for diagnostics, since they will come from the first fault, not later in tdb1_transaction_recover().

2011-09-14tdb2: add tdb_attribute_tdb1_max_deadRusty Russell1-1/+0
This allows us to simulate the old "volatile" flag for tdb1. It's not necessary for tdb2. As this is the last function in tdb1.h, we remove that file. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit b8e64e9346793164651a36eccb3c205077e5c91b)
2011-09-14tdb2: unify tdb1_parse_record into tdb_parse_recordRusty Russell1-5/+6
Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 3352e4e947777d4a90a2dd4f3037e1e494231b25)
2011-09-14tdb2: unify tdb1_chainlock et al. into tdb_chainlockRusty Russell1-2/+0
Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit ceb2f3eacbad917ee990afbc3dd800bfb0607887)
2011-09-14tdb2: unify tdb1_open into tdb_openRusty Russell1-3/+0
Finally, we gut tdb1_open() to the tdb1-specific parts, and call it from tdb_open if they specify the TDB_VERSION1 flag or the version is a TDB1. We also unify tdb_close(), based on the TDB_VERSION1 flag. Note that tdb_open(TDB_VERSION1) will fail on an existing tdb if it's a TDB2.

2011-09-14tdb2: merge tdb1_context into tdb_context.Rusty Russell1-155/+47
Finally, we split out the tdb2-specific parts of tdb_context, and put them into a "tdb2" sub-struct; the tdb1 parts go into a "tdb1" sub-struct. We get rido of tdb1_context and use tdb_context everywhere. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit bbeb528e74c0e234e1f724ac8d54be404cfc6f9a)
2011-09-14tdb2: use tdb->flags & TDB_RDONLY instead of tdb->read_only for TDB1 code.Rusty Russell1-1/+0
There's also a semantic change here: for tdb1, being read-only meant no locking, and it was an error to try to lock a r/o database. For TDB2, you'd need to specify TDB_NOLOCK, which suppresses locking silently.

2011-09-14tdb2: Make TDB1 use the same tdb_hash() wrapper as TDB2Rusty Russell1-2/+9
This means converting the tdb1 inbuilt hash functions to the tdb2-style, so they return 64 bit. We truncate to 32 bit everywhere but in tdb_check() which needs to do so explicitly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 3e46dde21261966941469a6c75e1b45cd2d26324)
2011-09-14tdb2: make tdb1 use same low-level lock functions.Rusty Russell1-3/+39
This means they will use the TDB_ATTRIBUTE_FLOCK functions, and get automatic reopen support. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit fbad02b680b6cbc33ae305ae1cbcdead4eedc7b1)
2011-09-14tdb2: Make tdb1 use the tdb_file structure.Rusty Russell1-14/+3
Because tdb2 allows multiple opens of the same TDB, we separate out the file information from the struct tdb_context. Do the same for tdb1. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 60210a73ec08a7b34ba637ad19e6749cf6dc1952)
2011-09-14tdb2: Make TDB1 code use TDB2's open flags.Rusty Russell1-1/+1
This means getting rid of TDB_VOLATILE (perhaps we should use an attribute for that?), TDB_INCOMPATIBLE_HASH (use the tdb_attribute_hash for that) and TDB_CLEAR_IF_FIRST (use the tdb_attribute_openhook for that). We also get rid of TDB_DISALLOW_NESTING: that's the default for TDB2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 22d0e0dc59fc9d7e0046fec6971ef478c2d604fd)
2011-09-14tdb2: Make tdb1 share tdb_store flags, struct tdb_data and TDB_MAGIC_FOOD.Rusty Russell1-19/+10
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 8a47d50d72ea62e378dc92b150c92c1317c73fa3)
2011-09-14tdb2: make TDB1 code use tdb2's TDB_ERROR and tdb_logerr()Rusty Russell1-11/+23
To do this, we make sure that the first few fields of tdb1_context and tdb_context are the same. This sweep also fixes up a few paths where we weren't setting tdb->ecode before our old logging function. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 919937354a331bb964564a11b5a5b80403ff8db9)
2011-09-14tdb2: make tdb1 headers include tdb2 headers.Rusty Russell1-29/+3
They're about to start sharing TDB2's definitions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 1e3138a0ad0c184d2ca49ce7bc47173eb2fe67bd)
2011-09-14tdb2: get rid of TDB1 mark and nonblock functions.Rusty Russell1-5/+2
We do this using hooks in tdb2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 444fade529f68eb2b0aebbc8de442478c5c6f916)
2011-09-14tdb2: remove _PUBLIC_ in tdb1 functions.Rusty Russell1-5/+0
They'll all be accessed via the tdb2 API. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 39f55294799c6443c0ad7bef09f1c113cf89d295)
2011-09-14tdb2: Remove unused tdb1 functions.Rusty Russell1-6/+3
We're going to use TDB2's API, so some TDB1 APIs are obviously unnecessary. We also get rid of USE_RIGHT_MERGES and TRACE code. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit b929638e3cfe629285af3ecd0813e03eaeaa1133)
2011-09-14tdb2: import TDB1 code.Rusty Russell1-0/+294
We import the entire codebase, putting a "tdb1_" prefix on the files and changing the "tdb_" prefix to "tdb1_" everywhere. The next patches will gradually merge it with the TDB2 code where necessary.
