var-expand: Add support for conditionals %{if;value-a,op,value-b:true-value:false-value}

lib: Fix strcasecmp mistake in var-expand

lib: Fix whitespace in var-expand.c

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

global: Change string position/length from unsigned int to size_t Mainly to avoid truncating >4GB strings, which might potentially cause some security holes. Normally there are other limits, which prevent such excessive strings from being created in the first place. I'm sure this didn't find everything. Maybe everything could be found with compiler warnings. -Wconversion kind of does it, but it gives way too many unnecessary warnings. These were mainly found with: grep " = strlen" egrep "unsigned int.*(size|len)"

lib: Add generic hashing support to var-expand Enables use of %{H;rounds=<rounds>,truncate=<bits>,salt=<salt>:field} syntax in any variable expansion. H is any supported hash algorithm or pkcs5 for PKCS#5 PBKDF2 using SHA256.

lib: Do not consume {} inside %{}

lib: API change - var_expand_func_table.func() can now return error. None of the existing functions were changed to return errors (yet).

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

lib: var_expand() code cleanup - Moved short %v expansion to its own function.

lib: var-expand: Removed var_expand_table_build(). Replaced it with explicit table construction at the one place it was used. Clang -Wvargargs complained about passing a char argument to va_start().

lib: var_has_key() properly ignores key=='\0' now.

lib: var_get_key() didn't handle %{long_variables} correctly This also fixes var_has_key()'s long_key handling.

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

Remove t_malloc in favour of t_malloc_no0 Using either t_malloc_no0 or t_malloc0 makes it clear whether the allocated memory is zeroed or not.

lib: var_expand() now expands %{nonexistent} to UNSUPPORTED_VARIABLE_nonexistent Earlier it was expanded to "nonexistent}", which looked more like a bug. This change hopefully makes it clear enough to understand when a variable isn't supported.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

Remove now-unnecessary direct stdlib.h #includes.

Removed all invocations of strtoll() and friends.

lib: If var_expand_with_funcs() function returns NULL, it should be treated the same as "" The previous behavior was to return "%{foo:bar}" as "foo:bar}".

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

liblib: Added negative %variable lengths to count backwards from the end of the value. For example %0.-2 for "12345" returns "123". Patch by Norbert Weinhold / Open-Xchange.

Updated copyright notices to include year 2014.

var_expand(): Fixed initializing variable to %N

var_expand*(): Fixed %N to work the same with little and big endian CPUs. Also use 64bit integer to do the MOD from, which should give somewhat better value distribution than with 32bit.

var_expand(): Added %N, which is the same as %H except based on MD5. This gives a better distribution of values than %H.

Oops :) Update copyrights to 2013 without breaking all .c files.
