2007-10-10r3056: added a id -> pointer data structure (a type of radix tree). This isAndrew Tridgell1-17/+11
an extremely efficient way of mapping from an integer handle (such as an open file handle) to a pointer (such as the structure containing the open file information). The code is taken from lib/idr.c in the 2.6 Linux kernel, and is very fast and space efficient. By using talloc it even has auto cleanup. This commit converts the handling of open file handles and open directory search handles to use the idtree routines. In combination with talloc destructors, this simplifies the structure handling in the pvfs backend a lot. For example, we no longer need to keep a linked list of open directory searches at all, and we no longer need to do linear scans of the list of open files on most operations. The end result is that the pvfs code is now extremely scalable. You can have 10s of thousands of open files and open searches and the code still runs very fast. I have also added a small optimisation into the file close path, to avoid looking in the byte range locking database if we know that there are no locks outstanding.

2007-10-10r3031: added support for lock cancelation, which effectively just triggers ↵Andrew Tridgell1-0/+4
an early lock timeout added support for more of the bizarre special lock offset semantics of w2k3 (This used to be commit d5bfc910b1200fb283e26572dc57fcf93652fd32)
2007-10-10r3012: added initial support for byte range locking in the posix vfs. This isAndrew Tridgell1-6/+15
enough for us to pass locktest, but does not yet support lock timeouts and some of the other esoteric features. (This used to be commit 58a92abd88f190bc60894a68e0528e95ae33fe39)
2007-10-10r2941: added pvfs_flush() implementation to the posix backendAndrew Tridgell1-0/+1
(This used to be commit dac00ef3b0d0f8467367d7b6ff77db7b63a042cc)
2007-10-10r2928: - fixed the handling of reserved names (rejecting them with ↵Andrew Tridgell1-2/+0
ACCESS_DENIED) - don't check for '.' specially in checking for legal names. Longhorn doesn't do this any more, and its a real pain. Longhorn allows for filenames ending in '.', and with as many '.' elements as you like. (This used to be commit 0a475175c53016bfa5b8246819676ddcd8b66feb)
2007-10-10r2927: imported the hash2 name mangling code from Samba3 into Samba4, butAndrew Tridgell1-0/+28
heavily modified to suit the Samba4 architecture. Samba4 with posix backend now passes the BASE-MANGLE test (This used to be commit ed52d69e8a065b6a8df2fb73c89be67acfdbca65)
2007-10-10r2751: this is a new ntvfs design which tries to solve:Stefan Metzmacher1-2/+0
- the stacking of modules - finding the modules private data - hide the ntvfs details from the calling layer - I set NTVFS_INTERFACE_VERSION 0 till we are closer to release (because we need to solve some async problems with the module stacking) metze (This used to be commit 3ff03b5cb21bb79afdd3b1609be9635f6688a539)
2007-10-10r2660: - converted the libcli/raw/ library to use talloc_increase_ref_count()Andrew Tridgell1-0/+8
rather than manual reference counts - properly support SMBexit in the cifs and posix backends - added a logoff method to all backends With these changes the RAW-CONTEXT test now passes against the posix backend (This used to be commit c315d6ac1cc40546fde1474702a6d66d07ee13c8)
2007-10-10r2561: completely redid the ntvfs module chaining code, You can now do ↵Andrew Tridgell1-0/+2
something like: ntvfs handler = nbench posix and the nbench pass-thru module will be called before the posix module. The chaining logic is now much saner, and less racy, with each level in the chain getting its own private pointer rather than relying on save/restore logic in the pass-thru module. The only pass-thru module we have at the moment is the nbench one (which records all traffic in a nbench compatibe format), but I plan on soon writing a "unixuid" pass-thru module that will implement the setegid()/setgroups()/seteuid() logic for standard posix uid handling. This separation of the posix backend from the uid handling should simplify the code, and make development easier. I also modified the nbench module so it can do multiple chaining, so if you want to you can do: ntvfs module = nbench nbench posix and it will save 2 copies of the log file in /tmp. This is really only useful for testing at the moment until we have more than one pass-thru module. (This used to be commit f84c0af35cb54c8fdc4933afefc18fa4c062aae4)
2007-10-10r2469: complete overhaul of the old-style RAW_SEARCH_ calls (the OS/2 andAndrew Tridgell1-1/+1
original core level calls). The old code was completely wrong in many respects. also fixed the EA_SIZE level in the server extended the RAW-SEARCH test suite to test the new code properly (This used to be commit 71480271ad84b57fcdde264a54bb2408cf783255)
2007-10-10r2436: the second big lump of posix vfs code.Andrew Tridgell1-19/+31
this is still just a skeleton, and many of the functions are just based on the simple vfs backend, they are there to allow me to run smbtorture tests against the real parts of the posix backend. (This used to be commit f2fa7fe565e89360dba3bb5434d3a6a36f398348)
2007-10-10r2404: the first large lump of posix vfs stuff.Andrew Tridgell1-1/+84
this is still very much a skeleton (with many limbs missing too!). I am committing this early to get some feedback on the approach taken. (This used to be commit 40d5cae5ebbfe328e193eadb685df6a370730299)
2007-10-10r2251: forgot to add vfs_posix.h in my last commitAndrew Tridgell1-0/+27
note that this is just a skeleton so far. More to come soon. (This used to be commit efc8850b9aa9348f5f7c4b342aa76dab1635e7d4)
