Introduce a new operation, splice, which copies data from one SMBCFILE
to another. Implement this operation using FSCTL_SRV_COPYCHUNK_WRITE for
SMB2+ protocols and using read+write for older protocols. Since the
operation may be long running, it takes a callback which gets called
periodically to indicate progress to the application and given an
opportunity to stop it.

The performance of these is minimal (these days) and they can return
invalid results when used as part of applications that do not use
sys_fork().

The potential previous lp_load of $HOME/.smb/smb.conf might have failed
halfway through and might have left globals initialized in an unwanted state.
So we should make sure to clean up before loading the dyn_CONFIGFILE()
There is no reason this can't be a normal constant string in the
loadparm system, now that we have lp_set_cmdline() to handle overrides
correctly.

This previously set the workgroup, which is a different thing, but
would have been the default if no domain was specified). This more
clearly sets the information from the credentials file into the
matching field in the credentials structure.

When called from a library, we don't want to call this, as we may
overwrite some of our calling program's context.

Following the review of this patch series by Derrell Lipman, remove
the seperate storage of the debug_stderr variable from the
libsmbclient SMBC_internal_data context.
Andrew Bartlett
This isn't quite what you would expect from this interface, but actually
avoids some really nasty situations if you ever have more than one
libsmbclient context in a process.
In the real world, if you have asked for DEBUG() to stderr in one part
of the code, you will want it globally, even in a different thread
(which in the past would have rest everything to stdout again, at
least while starting up).
Andrew Bartlett
This change improves the setup_logging() API so that callers which
wish to set up logging to stderr can simply ask for it, rather than
directly modify the dbf global variable.
Andrew Bartlett
Disable this by setting the environment variable LIBSMBCLIENT_NO_CCACHE, which
has the advantage over an smb.conf option to be easily settable per
application.
Can we enable this by default? This would be a change in behaviour, but this
feature is just too cool for everyone to catch up in the apps.
The patch would be
In smbc_free_context libsmbclient just called free() on the string options
so it assumes the callers have malloced them before setting them via smbc_set
calls.
Change to corretly malloc/free string options to the library.
Jeremy
gencache_get/set/del/iterate call gencache_init() internally anyway. And we've
been very lazy calling gencache_shutdown, so this seems not really required.
- Begin converting init functions to use SMB_THREAD_ONCE. libsmbclient
module-wide initialization is now moved into a separate function and called
via SMB_THREAD_ONCE.
- libsmbclient counts users (contexts) so that it can release global resources
when the last context is closed. That count of contexts is now protected by
a mutex.
Derrell
callers pass in a struct user_auth_info * instead. This commit causes
smbc_set_credentials() to print out a message telling callers to use
smbc_set_credentials_with_fallback() instead, as smbc_set_credentials()
has a broken API (no SMBCCTX * pointer). No more global variables used
in the connection manager API for client dfs calls.
Jeremy.
- Use const in function signatures whenever appropriate, to help prevent
errant scribbling on users' buffers. smbc_set_credentials() always acted as
if its formal parameters were const char *, and changing the formal
declaration to specify that should not cause any change to the ABI. It is
still allowable to pass a writable buffer to a function which specifies that
it will not write to the buffer.
I'm making this change only in master.
Derrell
- Most of the time, we can determine from the file system we're connecting to
whether it supports case sensitivity. In those cases, we now set the
internal case sensitivity flag automatically. For those cases where the
request to retrieve file system attributes fails, we'll use the
user-specified option value.
Derrell
*** THIS COMMIT CAUSES A CHANGE OF DEFAULT BEHAVIOR IN libsmbclient!!! ***
- libsmbclient now calls cli_set_case_sensitive() for a new CLI. By default,
it requests case-sensitive, but the old behavior of case-insensitive can be
requested with smbc_setOptionCaseSensitive(context, False);
The change of behavior is considered a bug fix, as it was previously
possible to accidentally overwrite a file that had the same case-insensitive
name but a different case-sensitive name as a previously-existing file,
while creating a new file.
Derrell
version.h changes rather frequently. Since it is included via includes.h,
this means each C file will be a cache miss. This applies to the following
situations:
* When building a new package with a new Samba version
* building in a git branch after calling mkversion.sh
after a new commit (i.e. virtually always)
This patch improves the situation in the following way:
* remove inlude "version.h" from includes.h
* Use samba_version_string() instead of SAMBA_VERSION_STRING
in files that use no other macro from version.h instead of
SAMBA_VERSION_STRING.
* explicitly include "version.h" in those files that use more
macros from "version.h" than just SAMBA_VERSION_STRING.

Here is a patch to allow many subsystems to be re-initialized. The only
functional change I made was to remove the null context tracking, as the memory
allocated here is designed to be left for the complete lifetime of the program.
Freeing this early (when all smb contexts are destroyed) could crash other
users of talloc.
Jeremy.
(This used to be commit 8c630efd25)
Brian Sheehan provided a nice patch intended for the 3.0 code base. This
commit applies a similar patch for the 3.3 code base. It adds a new public
function to libsmbclient -- smbc_set_credentials() -- that may be called from
the authentication callback when DFS referrals are in use.
Derrell
(This used to be commit 888f922bd0)
During my initial plans for, and the subsequent discussion of a more
significant change to the API for libsmbclient, I had removed the
AuthDataWithContext usage, in favor of a more generalized planned interface.
When the API returned to its original state, I neglected to reinsert this
code.
Use of an authentication function with the context can be tested using
examples/libsmbclient/testbrowse -C
