* Remove dead USE_OWN_COMPOSE-protected codeRan Benita2016-10-192-174/+0
| | | | | | | | | | | | The build doesn't provide any way to define this option. It also refers to files (imComp.h) and functions (e.g. XimCompInitTables(), XimCompProcessSym()) which are not found anywhere, and the ordinary Compose implementation in xim doesn't use any of it.

* Don't try so hard to find a matching font with the given encodingJon TURNEY2016-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | See http://sourceware.org/bugzilla/show_bug.cgi?id=10948 Currently, if the locale is UTF-8, no CJK fonts are installed, and someone does XCreateFontSet() with a font name of "*", we end up asking the server to list the (non-existent) fonts 11 times for each CJK encoding, which can take a while. A * wildcard can match multiple components in a XLFD name in XListFonts(), so there's no need to try adding more than one to get a match. We do try once with a leading '*-' in case the fontname isn't a full well-formed XLFD name, maybe even that isn't needed?

* Fix overflow checks in _XkbReadKeySyms when key_sym_map is already createdAlan Coopersmith2016-10-191-5/+4
| | | | | | | | | | | | | | | | | | | | We were checking to make sure that the largest keysym value was within the range of the allocated buffer, but checking against different limits in the not-yet-allocated vs. the already-allocated branches. The check should be the same in both, and reflect the size used for the allocation, which is based on the maximum key code value, so we move it to be a common check, before we branch, instead of duplicating in each branch. map->key_sym_map is an array of XkbSymMapRec structs, [0..max_key_code] map->syms is the array for which num_syms is recorded, hence is not the right value to check for ensuring our key_sym_map accesses are in range.

| | | | | | | | | | | | | This function performs operations on a region, and when finished, checks to see if it should compact the rectangle list. If the number of rectangles for which memory is allocated in the list is more than twice the number used, it tries to shrink. realloc() should not fail in this case, but if it does, might as well keep the correct value for the number of allocated rectangles, so we don't try to grow it unnecessarily later if adding to the region.

* lcfile: skip over any null entries in args listAlan Coopersmith2016-10-191-20/+15
| | | | | | | | | | | | | | | | | | Previous code seemed to assume that printf("%s", NULL) would result in a 0-length string, not "(null)" or similar, but since there's no point looking for files in "(null)/filepath...", instead we just skip over NULL entries in search paths when generating file names. In the *DirName() functions, this effectively just moves the "bail on NULL in arg[i]" check up from the later code that assigned it to targetdir and then bailed if that was NULL. Not sure how there ever could be a NULL in arg[i], given the current implementation of XlcParsePath, but it's easy enough to check once and reject up front instead of on every reference.

* XIM: Fix race on focus change: set 'FABRICATED' only when keyev filters in ↵Egbert Eich2016-10-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | place. When synthesized key events are sent on commit XIM sets the 'fabricated' flag so that the keypress handler knows that these were not real events. This also happens when committing due to the loss of focus. However in this case the keypress/release filters which consume and unset this flag are no longer in the filter chain. So the flag is erronously set when a real keyboard event is received after focus has been regained. So the first event is wrongly treated as a fabricated key in the keypress handler which will at the same time reset the flag so the second key event is treated correctly. This fix only sets the flag when at least one of the keyboard filters is in place. How to reproduce this bug: run scim, choose a Japanese input method start two instances of xterm: start typing in one xterm (this should pop up an IM window). Without comitting (hitting 'enter') move focus to the other xterm, then move focus back. Start typing again. The first character will be committed immediately without popping up an input window. With this fix this behavior is gone. See also: https://bugzilla.novell.com/show_bug.cgi?id=239698 Signed-off-by: Egbert Eich <eich@freedesktop.org> Backported-to-NX-by: Ulrich Sibiller <uli42@gmx.de>

Adjust _XGetRequest() (called by the GetReqExtra macro) to double-check the requested length and invalidate "req" when this happens. Users of GetReqExtra passing lengths greater than the Xlib buffer size (normally 16K) must check "req" and fail gracefully instead of crashing. Any callers of GetReqExtra that do not check "req" for NULL will experience this change, in the pathological case, as a NULL dereference instead of a buffer overflow. This is an improvement, but the documentation for GetReqExtra has been updated to reflect the need to check the value of "req" after the call.
