2011-03-30Fix convert_string() to take a *converted_size arg. and return a bool.Jeremy Allison1-34/+40
Makes these interfaces much harder to misuse and easier to ensure error checking. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Wed Mar 30 23:59:37 CEST 2011 on sn-devel-104

2011-03-29charconv: Fix the slow-path character conversionsVolker Lendecke1-3/+3
This reverts a part of 0189087e257f. That one might have fixed the fast path, but it broke the slow path. convert_string_internal returns 0/-1 despite the size_t result type and the misleading comment. If you follow the path to smb_iconv and for example iconv_copy(), you will see that this routine returns 0 even after it copied something. How to check: Use German locale, and do an smbclient "allinfo" on a file modified in march (März in German). Notice the "ä". Before 0189087 this printed correctly, after 0189087 it cut off the fields after the M for März.

is configured. As discovered by David Disseldorp <ddiss@suse.de>, convert_string_talloc() doesn't always return consistent results for a zero length string. The API states an incoming string must *always* contain the terminating null, but unfotunately too much code expects passing in a zero source length to return a null terminated string, so at least ensure we return a correct null string in the required character set and return the correct length. Also ensure we cannot return a zero length for a converted string (we ensure that the returned buffer is always allocated and zero terminated anyway) as calling code depends on the fact that returning true from this function will *always* return a non-zero length (as it must include the terminating null). Jeremy. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Fri Mar 25 23:25:40 CET 2011 on sn-devel-104

2011-03-23s3-lib Remove the clobber_region() code.Andrew Bartlett1-68/+22
This code wrote to the full buffer in fstrcpy(), pstrcpy() and other fixed-length string manipulation functions. The hope of this code was to find out at run time if we were mixing up pstring and fstring etc, and to record where this came from. It has a runtime performance impact (particularly if compiled with --enable-developer). It is being removed because of the complexity it adds, and the distinct lack of bugs that this complexity has been credited in finding. The macro-based compile-time checking of string sizes remains. Andrew Bartlett
2011-03-14Fix bug #8005 - smbtorture4 BASE-TCONDEV fails when tested on SambaJeremy Allison1-2/+6
When pulling non-aligned ucs2 strings, we neglected to add in the pad byte to the buffer length we've eaten. This caused the device string in TCONX (which seems to be one of the few places that uses non-aligned ucs2 strings) to be incorrectly read. Volker please check. Jeremy.
2011-02-18lib/util/charset Add back setlocale(), but only when called from binariesAndrew Bartlett1-1/+1
When called from a library, we don't want to call this, as we may overwrite some of our calling program's context. Andrew Bartlett Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Fri Feb 18 09:29:35 CET 2011 on sn-devel-104
2011-02-18lib/util/charcnv Move iconv handle setup in commonAndrew Bartlett1-290/+12
We now use the struct smb_iconv_convenience at the core of all our iconv code, and use global_iconv_convenience for the callers that don't specify one. Andrew Bartlett

This file is always installed, and is only even required for the old, depricated mangle hash method. Andrew Bartlett
2011-02-18charset Remove use of {isupper,islower,toupper,tolower}_w functionsAndrew Bartlett1-1/+1
These now call the common _m functions that consider UTF16 code points. This removes the code which will make up a 'lame' table in memory, as this can just as correctly be handled by running the algorithm at runtime (which is to call toupper() and tolower() on characters < 128). When used, a top level waf build will always locate the correct table - in the build tree or outside - due to relinking the installed binary. Andrew Bartlett

2010-11-03s3:lib/charcnv: add next_codepoint_ext() that accepts input charset.Michael Adam1-11/+32
next_codepoint() takes as string in CH_UNIX encoding and returns the unicode codepoint of the next (possibly multibyte) character of the input string. The new next_codepoint_ext() function adds the encoding of the input string as a parameter. next_codepoint() now only calls next_codepoint_ext() with CH_UNIX als src_charset argument.

This removes calls to push_*_allocate() and pull_*_allocate(), as well as convert_string_allocate, as they are not in the common API To allow transition to a common charcnv in future, provide Samba4-like strupper functions in source3/lib/charcnv.c (the actual implementation remains distinct, but the API is now shared) Andrew Bartlett
2009-04-14Solve some of the conflict between Samba3 and Samba4 push_stringAndrew Bartlett1-5/+43
This renames push_string in Samba3 into push_string_base and push_string_check for the two different use cases. This should allow push_string to be imported from Samba4, using it's calling conventions.

old server. There was some code in pull_ucs2_base_talloc() to cope with this case which hadn't been added to pull_ascii_base_talloc(). The older Samba returns non unicode names which is why you are seeing this codepath being executed. Unify the logic in pull_ascii_base_talloc() and pull_ucs2_base_talloc(). Jeremy.
2008-08-12Fix bug 5686 - libsmbclient segfaults with more than one SMBCCTX.Jeremy Allison1-3/+3
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 8c630efd25cf17aff59448ca05c1b44a41964b16)
