2012-06-19TDB2: remove TDB1 compatibility.Rusty Russell1-234/+0
This rips out all the TDB1 compatibility from tdb2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-09-14tdb2: log allocation failures in tdb1 backend.Rusty Russell1-7/+17
The TDB2 tests are stricter about this; they want every error logged. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 670ba98f74b52df541d153eeab9d3310932e75cd)
2011-09-14tdb2: add tdb_attribute_tdb1_max_deadRusty Russell1-16/+13
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_chainlock et al. into tdb_chainlockRusty Russell1-3/+3
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 Russell1-295/+76
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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit c8c3b3568677e8b0105f84e4ab068c580faf4591)
2011-09-14tdb2: add TDB_ATTRIBUTE_TDB1_HASHSIZERusty Russell1-5/+22
This replaces the tdb1_open "hash_size" argument. It will only be valid when you call tdb_open() with O_CREAT in open_flags, and TDB_VERSION1 in tdb_flags. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 49475d68deecd0b31597ed6094229171d2699b11)
2011-09-14tdb2: make tdb1_open use attributes for logging, hash function.Rusty Russell1-17/+37
This brings it closer to tdb_open(), so we can unify more easily. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit a446f1d4d161d66bbb19ba2551cf6429a4865964)
2011-09-14tdb2: remove double-open detection for TDB1 databases.Rusty Russell1-38/+0
This is a percursor to unifying with tdb_open() from tdb2, which handles this itself. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 97224cbbe29e76522ec38d031c54b1cadce8ae03)
2011-09-14tdb2: merge tdb1_context into tdb_context.Rusty Russell1-35/+35
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/+1
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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 4dc29a338fadeac805b369b4b0851c02f1b152c7)
2011-09-14tdb2: Make TDB1 use the same tdb_hash() wrapper as TDB2Rusty Russell1-8/+3
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 Russell1-0/+2
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 Russell1-27/+38
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: add TDB_VERSION1 flag.Rusty Russell1-1/+1
This will be set for old TDBs; we can start distinguishing paths based on it now. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 2b50be90a23893a06e0f1436a31d18b97ad0e11d)
2011-09-14tdb2: Make TDB1 code use TDB2's open flags.Rusty Russell1-73/+14
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: approximate INCOMPATIBLE_HASH flag with tdb1_incompatible_hash()Rusty Russell1-23/+24
Rather than leak TDB_INCOMPATIBLE_HASH through to the TDB2 API, we make it that if they use the tdb1_incompatible_hash function as their hash, then we treat it as if they had specified the TDB_INCOMPATIBLE_HASH flag (ie. we mark the header so it's unusable by tdb < 1.2.6). This precludes the possibility of using TDB_INCOMPATIBLE_HASH with a custom hash function: that used to allow the user to ensure that old TDB versions couldn't open the TDB file (and recent ones check the header to ensure they're using the right hash). But that's a small loss. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 3004f7e89a5978064b4fb29c1027e6d0d39e9418)
2011-09-14tdb2: Make tdb1 share tdb_store flags, struct tdb_data and TDB_MAGIC_FOOD.Rusty Russell1-8/+8
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 Russell1-47/+51
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: remove TDB1 TDB_NO_FSYNC environment variable hack.Rusty Russell1-4/+0
The caller should do this: the SAMBA compatibility later does. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 75a6a6ad64156ef3b13493be2970ae3cb99ccf8b)
2011-09-14tdb2: get rid of TDB1 mark and nonblock functions.Rusty Russell1-2/+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 Russell1-4/+4
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 Russell1-112/+0
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/+609
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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 19e6c1a250ade1e7204ada17163294855585e825)
