2011-09-14tdb2: don't continue if tdb1_find fails.Rusty Russell1-16/+37
The TDB1 code's tdb1_find() returns 0 on error; the callers should not assume that the error means that the entry wasn't found, but use last_error to determine it. This was found by looking at how long the failure path testing for test/run-10-simple-store.c was taking under valgrind, ie: valgrind -q ./run-10-simple-store --show-slowest This change dropped the time for that test from 53 seconds to 19 seconds.

2011-09-14tdb2: log allocation failures in tdb1 backend.Rusty Russell1-1/+3
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 stats to tdb1 backend.Rusty Russell1-5/+12
It's actually quite a good fit; we use compare_wrong_bucket for dead records, which is kind of correct (they should be in the free list). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit a3e4ebff2eb9dc2e386160b8acf77d70236f4def)
2011-09-14tdb2: increment seqnum on tdb_wipe_all in tdb1 backend.Rusty Russell1-0/+1

2011-09-14tdb2: log an error when calling tdb_store() on read-only TDB in tdb1 backend.Rusty Russell1-1/+3
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit b236a8dcc37bb864b632a2898a64f3c9bf75b4ac)
2011-09-14tdb2: make tdb1_null static.Rusty Russell1-4/+5
It's only used in two files, make it static in one and do it manually in the other. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 8571daf007f03a2888566dbaae8a5849ffba60f3)
2011-09-14tdb2: tdb_repackRusty Russell1-102/+0
Move the tdb1_repack() code into the core, make it general, rename to tdb_repack(). It's generic code: copy database into temporary, wipe it, copy back. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit e487983a4099b6f760056ff7182f2ff543e6da71)
2011-09-14tdb2: unify tdb1_parse_record into tdb_parse_recordRusty Russell1-25/+7
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 Russell1-8/+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_traverse into tdb_traverseRusty Russell1-2/+2
Switch on the TDB_VERSION1 flag; we now only do a tdb1_traverse_read on a read-only database, as there is no tdb2 equivalent. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit cc2d609dfca7192305ad477b8c2b52cfdc1aa9be)
2011-09-14tdb2: unify tdb1_store into tdb_storeRusty Russell1-0/+1
Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 2bba2a856a6cfdb93085b701557850bc1da99587)

2011-09-14tdb2: unify tdb1_fetch into tdb_fetchRusty Russell1-4/+5
Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 08c05da588018c6b76834e57b66d525546643708)
2011-09-14tdb2: unify tdb1_store into tdb_storeRusty Russell1-0/+3
Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 98c754ffe65bc335f66161d6cc8705d4ea2710ec)
2011-09-14tdb2: unify tdb1_open into tdb_openRusty Russell1-7/+7
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 Russell1-6/+6
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 Russell1-1/+1
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: merge tdb1_context into tdb_context.Rusty Russell1-45/+45
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 Russell1-2/+2
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 Russell1-6/+6
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 the tdb_file structure.Rusty Russell1-3/+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 Russell1-5/+5
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 Russell1-29/+29
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 Russell1-43/+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: get rid of TDB1 mark and nonblock functions.Rusty Russell1-1/+1
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 Russell1-13/+13
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 Russell1-78/+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/+993
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)
