Adjust all struct dirent creations (again), this time to use offsetof().

The dirent struct is not packed, so offsetof(dirent, d_name) != sizeof(dirent).
Thus in order not to waste the alignment bytes (which are significant,
on x86_64 at least, sizeof(dirent)==32, but offsetof(...)=26.)

This is also the most portable way to handle things, and should
work just fine in cross-platform code that has a non-zero-sized d_name.

file_systems & Tracker: Do not assume sizeof(dirent) contains 1 byte for the name.

At present, it does, but that is an oddity we have preserved from BeOS
that the next commit is going to remove. (This commit thus wastes 1 byte
without the following one.)

Most changes are pretty straightforward: only a +1 is needed,
and a few removed from sizing calculations. Some filesystems like UDF
originally passed back the length with the \0 included, so they have
been adjusted further. UFS2 had some other sizing problems which are also
corrected in this commit.

block_cache: Change signature of *_etc() functions

* This allows file systems to retrieve the actual error code on a
failure, and report it to the user.
* All affected file systems have been adjusted to the API change.
This is a binary incompatible change.

bfs: keep valid dirent->d_reclen in case of bad name

BFS: Use MAX_INDEX_KEY_LENGTH for queries.

* INODE_FILE_NAME_LENGTH makes no sense here, even though this change
is not supposed to actually change anything besides the naming.

BFS: Removed match empty string logic.

* This produces more reliable query results no matter which index
gets chosen to run the query.
* This fixes the final part of #13254.

bfs: Handle type 'TIME' as int32 in queries.

* This fixes ticket #6734.

bfs: Query parser needs to filter out escape char.

* When escaping operator/quote characters, the character was properly
ignored. However, the escape char was left in the string which
altered the query.
* This fixes bug #10976.

bfs: Minor cleanup.

* Added helper methods for operator/equation characters.

Coding style cleanup, no functional change.

bfs: Always check if NodeGetter succeeded.

* There were quite a few cases that just assumed that the disk access
would succeed.
* This also fixes bug #12962.

bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.

bfs: removed kernel_cpp.h's new operator.

* This fixes bug #9715 from the POV of BFS, ie. the new operator seems
to call the constructor on a NULL object on failure.

Fixed warning when compiled with DEBUG=1 but an empty D().

Move B_MIME_STRING_TYPE to <TypeConstants.h>

Add a private B_ATTR_CHANGE_NOTIFICATION flag to the open query syscall to tell the query to send notifications when an entry attribute changed and the entry stays in the query. Previously you only get created and removed messages, now you can also get updated messages. Only implement it for bfs.
Fix copy right.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39131 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the query code again to send B_ENTRY_REMOVED/B_ENTRY_CREATED
notifications if an inode in a query result was moved/renamed - this time all
the information is correct, though.
* While I did not introduce B_ENTRY_MOVED for queries yet, this should make
adding it very simple (left as an excercise for the reader ;-))

one or two remove messages were generated, as the query code produces
remove/create notifications on renames. Will check next if that also happens
on BeOS, as it doesn't really make much sense.

mail.

failed to evaluate, the whole term was ignored. Also, if the left term got

Only queries non-indexed attributes if the B_QUERY_NON_INDEXED flag was
passed during construction of the Query.
Only live queries are now registered with the BVolume (for now - since Be's kernel
doesn't free queries when an app has crashed, we might want to have a work-around
for that one day [or just a new kernel :)]).

The empty string ("", length 0) will now be replaced with ("", length 1) in
queries, to let the BPlusTree::Find() method search for it (there can't be
any keys in the tree with length 0).
That means that the query 'META:url=""' will now return all files where the
attribute "META:url" is present but empty.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2401 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed the bug in the query code: B_MIME_STRING_TYPE was not correctly
translated into B_STRING_TYPE for the key comparison (it was translated
but not saved under the new type).
compareKeys() will now return -1 if it didn't know the type to compare.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2121 a95241bf-73f2-0310-859d-f6bbb57e9c96

Equation::Match() unlocked the small data section too soon (the contents
could be changed before or during the comparison).

Only queries non-indexed attributes if the B_QUERY_NON_INDEXED flag was
passed during construction of the Query.
Only live queries are now registered with the BVolume (for now - since Be's kernel
doesn't free queries when an app has crashed, we might want to have a work-around
for that one day [or just a new kernel :)]).
Small cleanups.

The empty string ("", length 0) will now be replaced with ("", length 1) in
queries, to let the BPlusTree::Find() method search for it (there can't be
any keys in the tree with length 0).
That means that the query 'META:url=""' will now return all files where the
attribute "META:url" is present but empty.

Fixed the bug in the query code: B_MIME_STRING_TYPE was not correctly
translated into B_STRING_TYPE for the key comparison (it was translated
but not saved under the new type).
compareKeys() will now return -1 if it didn't know the type to compare.

Now uses Inode::GetName() where appropriate.
Fixed a bigger race condition when matching against the name index.

Equation::Match() unlocked the small data section too soon (the contents
could be changed before or during the comparison).
Some style changes.

Added private non-implemented copy constructor and assignment operators
for many classes for the sake of completeness.
Added a Transaction::IsStarted() method to not let it look like as if the
transaction is started more than once.
Changes made after suggestions from Mike Nordell, again :-)

Fixed the dirent.d_reclen calculation - define KEEP_WRONG_DIRENT_RECLEN to
enable the old and compatible behaviour (on BeOS R5, all available file
systems seem to do that wrong).
