* pattern: Merge identical branchesNick Wellnhofer2023-02-211-16/+6
| | | | Fixes #479.
* Remove explicit integer castsNick Wellnhofer2022-09-011-2/+2
| | | | | | | | | | | | | | | | | | | | Remove explicit integer casts as final operation - in assignments - when passing arguments - when returning values Remove casts - to the same type - from certain range-bound values The main motivation is that these explicit casts don't change the result of operations and only render UBSan's implicit-conversion checks useless. Removing these casts allows UBSan to detect cases where truncation or sign-changes occur unexpectedly. Document some explicit casts as truncating and add a few missing ones.
* Remove DOCBparserNick Wellnhofer2022-03-041-12/+0
| | | | | | | This code has been broken and deprecated since version 2.6.0, released in 2003. Because of a bug in commit 961b535c, DOCBparser.c was never compiled since 2012. I couldn't find a Debian package using any of its symbols, so it seems safe to remove this module.
* Remove elfgcchack.hNick Wellnhofer2022-02-201-2/+0
| | | | | The same optimization can be enabled with -fno-semantic-interposition since GCC 5. clang has always used this option by default.
* Large batch of typo fixesJared Yanovich2019-09-301-4/+4
| | | | Closes #109.
* Fix call stack overflow in xmlFreePatternNick Wellnhofer2019-04-251-3/+6
| | | | | | | | Since xmlFreePattern tried to free the next pattern recursively, its behavior is identical to xmlFreePatternList. Make it call xmlFreePatternList to avoid call stack overflows. Found by OSS-Fuzz.
* Fix memory leak in pattern error pathNick Wellnhofer2017-05-271-0/+1
| | | | Found with libFuzzer and ASan.
* Big space and tab cleanupDaniel Veillard2012-09-111-89/+89
| | | | Remove all space before tabs and space and tabs at end of lines.

* Fix -Wempty-body warning from clangNico Weber2012-03-051-1/+2
| | | | | | clang recently grew a warning on `for (...);`. This patch fixes all two instances of this pattern in libxml. The changes don't modify the code semantic.

| | | | | | | | | | | | | | | | | | | | | | | | | | * xpath.c: Applied patch from Rob Richards, fixing a potential memory leak in xmlXPathTryStreamCompile(), when a list of namespaces was assigned to the XPath compilation context; here a new namespace list was created and passed to xmlPatterncompile(); but this list was not freed afterwards. Additionally we avoid now in xmlXPathTryStreamCompile() to compile the expression, if it has a colon - indicating prefixed name tests - and no namespace list was given. The streaming XPath mechanism needs a namespace list at compilation time (unlike normal XPath, where we can bind namespace names to prefixes at execution time). * pattern.c: Enhanced to use a string dict for local-names, ns-prefixes and and namespace-names. Fixed xmlStreamPushInternal() not to use string-pointer comparison if a dict is available; this won't work, since one does not know it the given strings originate from the same dict - and they normally don't do, since e.g. namespaces are hold on xmlNs->href. I think this would be worth an investigation: if we can add a @doc field to xmlNs and put the @href in to a additionan namespace dict hold in xmlDoc. Daniel will surely not like this idea :-) But evaluation of tons of elements/attributes in namespaces with xmlStrEqual() isn't the way we should go forever.

* Fixed bug #322928, reported by Erich Schubert: The bug was in pattern.c,Kasimier T. Buchcik2006-01-051-55/+239
| | | | | | | | | | | | | * pattern.c xpath.c include/libxml/pattern.h: Fixed bug #322928, reported by Erich Schubert: The bug was in pattern.c, which is used for a tiny subset of xpath expression which can be evaluated in an optimized way. The doc-node was never considered when evaluating "//" expressions. Additionally, we fixed resolution to nodes of any type in pattern.c; i.e. a "//." didn't work yet, as it did select only element-nodes. Due to this issue the pushing of nodes in xpath.c needed to be adjusted as well.
* Fixed a potential memory leak in xmlSchemaCheckCSelectorXPath() when anKasimier T. Buchcik2005-10-191-14/+170
| | | | | | | | | | | | | * xmlschemas.c: Fixed a potential memory leak in xmlSchemaCheckCSelectorXPath() when an internal error occurs. Fixed setting of ctxt->err to the given error code in the parsing error functions. * pattern.c: Added internal xmlCompileIDCXPathPath() as a starting point for IDC XPath compilation; this and some other tiny changes fixes issues regarding whitespace in the expressions and IDC selector/field relevant restrictions of the subset of XPath. Fixed a missing blocking of attributes in xmlStreamPushInternal().
* Silenced intel compiler warnings (reported by Kjartan Maraas, bugKasimier T. Buchcik2005-10-171-4/+2
| | | | | | | | | | | * tree.c pattern.c: Silenced intel compiler warnings (reported by Kjartan Maraas, bug #318517). * xmlschemas.c: The above changes in pattern.c revealed an inconsistency wrt IDCs: we now _only_ pop XPath states, if we really pushed them beforehand; this was previously not checked for the case when we discover an element node to be invalid wrt the content model. Fixed segfault in xmlSchemaGetEffectiveValueConstraint().
* Fixed some identity-constraint issues: Restructured IDC node-tablesKasimier T. Buchcik2005-10-141-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | * xmlschemas.c: Fixed some identity-constraint issues: Restructured IDC node-tables Allowed IDCs to resolve also to nodes of complex type with simple content. Added check for keyrefs with references to keyrefs. IDC target-nodes were interferring with IDC node-tables, since they used one list of entries only. I separated this one big list into 3 lists: 1 for IDC node-table entries, 1 for _duplicates_ of IDC node-table entries and 1 for IDC target-nodes. More code, but cleaner and it works at last. Keyrefs will fail to resolve to duplicate key/unique entries. I thought this was already working this way, but it didn't. The wording of the definition for [node table] in the spec can lead to a scenario, where keyrefs resolve perfectly, even if the relevant key-sequences of the referenced key/unique have duplicates in the subtree. Currently only Saxon 8.5.1 is dissallowing resolution to duplicate entries correctly - we will follow Saxon here. Removed some intel compiler warnings (reported by Kjartan Maraas, bug #318517). * pattern.c: Fixed an IDC-XPath problem when resolving to attributes.
