2007-12-18Add a in-memory cacheVolker Lendecke1-41/+23
This is a more general API that caches data with a LRU scheme. See include/cache.h. No comments yet, I'm still working on it. But Jeremy has given me a hint in one of his checkins that he would like to make use of this now. The idea is that we get rid of all our silly little caches and merge them all into one cache that we can then very easily trim, for example even with a smbcontrol message if someone decides memory is tight. The main user is the stat cache, this patch also converts the getwd cache. More caches to come. (This used to be commit 7a911b35713538d82001a3c9f34152e293fe1943)
2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-4/+4
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)

doing this because for the clustering the marshalling is needed in more than one place, so I wanted a decent routine to marshall a message_rec struct which was not there before. Tridge, this seems about the same speed as it used to be before, the librpc/ndr overhead in my tests was under the noise. Volker (This used to be commit eaefd00563173dfabb7716c5695ac0a2f7139bb6)

2003-07-27Allow the stat cache to better handle invalid multibyte strings, by usingAndrew Bartlett1-8/+25
strdup_upper(). This function may fail - and we can just drop out of using the cache in that case. (Rather than panicing). This also should get us closer to supporting all of the weird 'longer/shorter' on uppercase/lowercase. Andrew Bartlett (This used to be commit d4c9261725578231079ed83e8e6584f12bd1cc43)

VFS_ macros at system side. We currently have one clash with AIX and its VFS_LOCK. Compiled and tested -- no new functionality or code, just plain rename of macros for yet-unreleased VFS API version.

a pstrcpy/fstrcpy or at most a safe_strcpy(). These have the advantage of being compiler-verifiable. Get these out of the way, along with a rewrite of 'get_short_archi' in the spoolss client and server. (This pushes around const string pointers, rather than copied strings).

2000-11-21Fix for updating of print queues changed from a local box. Essentially,Jeremy Allison1-1/+1
this makes sure that the change messages sent to ourselves are handled synchronously w.r.t. other smb packets incoming. Jeremy. (This used to be commit 78a13074455618308d048d1c69f62e660988eb90)
2000-10-19Ok - this is a big patch - and it may break smbd a bit (althoughJeremy Allison1-1/+1
I hope not). If you encounter strange file-serving behavior after this patch then back it out. I analysed our stat() usage and realised we were doing approx. 3 stat calls per open, and 2 per getattr/setattr. This patch should fix all that. It causes the stat struct returned from unix_convert() (which now *must* be passed a valid SMB_STRUCT_STAT pointer) to be passed through into the open code. This should prevent the multiple stats that were being done so as not to violate layer encapsulation in the API's. Herb - if you could run a NetBench test with this code and do a padc/par syscall test and also run with the current 2.2.0 code and test the padc/par syscalls I'd appreciate it - you should find the number of stat calls reduced - not sure by how much. The patch depends on unix_convert() actually finding the file and returning a stat struct, or returning a zero'd out stat struct if the file didn't exist. I believe we can guarentee this to be the case - I just wasn't confident enough to make this an assertion before. Ok ok - I did write this whilst at the Miami conference..... sometimes you get a little free time at these things :-). Jeremy. (This used to be commit 66a5c05ec46b641224fbe01b30bd7e83571a2a1b)
2000-10-06Herb's warning fixes. Also the POSIX locking fix.Jeremy Allison1-27/+6
We now use our own vfs layer to do get/set acl calls (hurrah!). Jeremy. (This used to be commit dfe77c7046cbd65ee52aea7439f21503c1eac41d)
2000-10-06Restructuring of vfs layer to include a "this" pointer - can be an fsp orJeremy Allison1-1/+1
a conn struct depending on the call. We need this to have a clean NT ACL call interface. This will break any existing VFS libraries (that's why this is pre-release code). Andrew gets credit for this one :-) :-). In addition - added Herb's WITH_PROFILE changes - Herb - please examine the changes I've made to the smbd/reply.c code you added. The original code was very ugly and I have replaced it with a START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor. Please check this compiles ok with the --with-profile switch. Jeremy. (This used to be commit b07611f8159b0b3f42e7e02611be9f4d56de96f5)
