Surprisingly, this simple mistake wasn't caught by the tests OR valgrind under Linux, but on FreeBSD made one of the tests crash (behaviour n23), and it did appear under valgrind on that platform.

This patch changes the definitions to match the appropriate data type, and adds checks for some cases where we need to do so in Python (e.g. we convert to (signed) long long and use it as an (unsigned) off_t).

After applying the new transaction, we need to free it; however, jtrans_free() assumes op->buf points to a different place than op->pdata, and attempts to free both. Thus, to prevent a double free in the hand-crafted transaction, we need to set one of them to NULL. However, we currently set both to NULL, effectively leaking the memory used to store it. This patch fixes that bug, by simply removing one of the two assignments.

This broke the Python build, but went unnoticed because in all my repositories I had (purely by chance) a shared library in the libjio directory. This commit fixes this by making it look in the appropriate place, and also making libjio/Makefile to create a link to the library with the soname, so the Python interpreter can find the library (we don't need to install it because ldconfig will take care of creating it).

On 64-bit platforms that mismatch caused trouble, but luckily nothing that could cause corruption, since the resulting values were given to malloc(), which would fail. This issue came up when running the behaviour tests in Fedora 13. The patch fixes this by telling PyArg_ParseTuple() we are giving it a long instead of an int.

That was needed for writev(). However, existing instances of s# were not converted, and caused subtle but worrying memory corruption. This patch fixes that by using ssize_t in the appropriate places.

Transactions that were being committed when we set the flag are not a problem because they affect different portions of the file. This protects from the following scenario: - Commit data X to a range A-B: - Write the transaction 1 to the journal - Write the data to the file - Attempt to remove the journal file: fail - Commit data Y to a range A-B: success - Crash - jfsck(): - Finds transaction 1, writes data X to the file which corrupts things because data Y is the one that should be there. We also return -2 in those cases, which means the user should abort immediately, but this measure can help to prevent problems when the user is not careful or can't stop further commits.

Where in the second comparison we know it's safe because rv is >= 0. We could add a cast, but it would just make the code uglier for no real reason.

The fundamental reason for this change is to put the number of operations contained in the transaction at the end. That will allow us to write operations as they are added to the transaction, instead of waiting until commit time, which can improve performance on some operation-intensive workloads. Other changes include the addition of a much needed version number (which will hopefully keep the library backwards compatible in case of future disk format changes), a more robust checksum algorithm, and defined endianness of the stored data for portability purporses.

This patch lets the kernel know that using posix_fadvise(), so it can take actions based on that. Because posix_fadvise() was included in SUSv3 and so far we've relied just on SUSv2, we introduce a new header, compat.h, to provide a stub for that function so the library can be built in systems that do not implement it.

Otherwise, if we use a larger data type, we might get garbage because it will assume it's the size of an int. We had some cases when that could happen, and this patch gets rid of them.

While at it, also pass the flags when linking, because there may be relevant flags. We should use LDFLAGS for this, tho; but for now we'll take the simpler approach.
