* Fix pointer/int cast warnings on 64-bit WindowsNick Wellnhofer2017-10-091-1/+1
| | | | | | | | | | | On 64-bit Windows, `long` is 32 bits wide and can't hold a pointer. Switch to ptrdiff_t instead which should be the same size as a pointer on every somewhat sane platform without requiring C99 types like intptr_t. Fixes bug 788312. Thanks to J. Peter Mugaas for the report and initial patch.
* Fix cast-align warningsNick Wellnhofer2017-06-171-1/+1
| | | | | | | | | | | | | - Suppress warnings in xmlmemory.c by casting to 'void *'. - Remove unneeded cast in xmlschemas.c that caused a macro precedence error. - Add dummy fields to short structs in xmlschemas.c. This increases the size of the structs, but I can't see a better solution without using C11's _Alignof operator. There are still a couple of cast-align warnings in encoding.c. These are legitimate portability issues that can't be fixed without reworking the conversion functions.
* Fix copy-paste errors in error messagesNick Wellnhofer2017-06-111-3/+3

* Check for integer overflow in memory debug codeNick Wellnhofer2017-06-061-0/+21
| | | | | | Fixes bug 783026. Thanks to Pranjal Jumde for the report.
* Unsigned addition may overflow in xmlMallocAtomicLoc()David Kilzer2016-05-231-2/+10
| | | | | | | | | | | | | For https://bugzilla.gnome.org/show_bug.cgi?id=764616 This code is used only if turning memory allocation debug in configure with --with-mem-debug, which should never happen in real life, so not a serious issue. * xmlmemory.c: (MAX_SIZE_T): Macro to define maximum value of size_t. (xmlMallocAtomicLoc): Add bounds check. Fix description and use the correct function name in another error message.
* xmlMemUsed is not thread-safeMartin von Gagern2015-04-131-2/+12

This fixed some random errors on the Threads regression tests. * encoding.c, include/libxml/encoding.h: Enhanced the handling of UTF-16, UTF-16LE and UTF-16BE encodings. Now UTF-16 output is handled internally by default, with proper BOM and UTF-16LE encoding. Native UTF-16LE and UTF-16BE encoding will not generate BOM on output, and will be automatically recognized on input. * test/utf16lebom.xml, test/utf16bebom.xml, result/utf16?ebom*: added regression tests for above.
