4 daysplist: fix inverted strcmp in string to boolean conversionGravatar Arpit Jain1-2/+2
plist_dict_get_bool() compared the string value with strcmp() but treated a non-zero return as a match. strcmp() returns 0 on equality, so the conditions were inverted: "true" produced 0, "false" produced 1, and any other string also produced 1. The error branch could never be reached, since it required both comparisons to return 0 at once. The result is that the API returns the opposite of the stored value for both valid boolean strings, and returns true for strings that are not booleans at all, instead of reporting the conversion error. Compare == 0 in both conditions: input before after true 0 1 false 1 0 not-a-bool 1 error TRUE 1 error (empty) 1 error Signed-off-by: Arpit Jain <arpitjain099@gmail.com>

4 daysbytearray: Handle realloc() failure in byte_array_grow()Gravatar Comtea048-2/+72
byte_array_grow() assigned the result of realloc() directly to ba->data and increased the capacity even if realloc() failed, so the following memcpy() in byte_array_append() wrote to NULL + len. On failure, free the old buffer and leave the byte array in a failed state (data == NULL), which byte_array_append() already ignores. The callers check for that state: - the writers (bin, xml, json, openstep and the text output formats) return PLIST_ERR_NO_MEM instead of handing out a NULL/truncated buffer - node_to_xml() base64-encodes <data> directly into the grown buffer, so it must bail out there (only guarded by assert() before) - the OpenStep parser returns PLIST_ERR_NO_MEM for <hex data> instead of silently returning truncated data Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
6 daysptrarray: Handle realloc() failure in ptr_array_insert()Gravatar Comtea044-12/+32
ptr_array_insert() assigned the result of realloc() directly to pa->pdata and bumped the capacity without checking for failure, so on out-of-memory the old buffer was leaked and the following store or memmove() wrote through a NULL pointer. Keep the old buffer on failure and return -1 from ptr_array_insert() and ptr_array_add(). The callers now handle the error: - the array lookup cache (plist.c) is dropped instead of silently going out of sync with the node list; lookups then fall back to walking the children, as they do before the cache exists - bplist parsing (used_indexes) and serialization (objects) return PLIST_ERR_NO_MEM; ignoring the error in parse_bin_node_at_index() would otherwise loop forever since the array never grows Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Avoid undefined behavior when serializing malformed PLIST_DATE values containing NaN, infinity, or values outside the Time64_T range. Add a shared helper for checked date conversion and use it across writer paths.

2026-03-22Add OpenStep coercion support for non-OpenStep plist typesGravatar Nikias Bassen5-35/+164
- Use PLIST_OPT_COERCE option to coerce PLIST_BOOLEAN, PLIST_DATE, PLIST_UID, and PLIST_NULL to OpenStep-compatible types (1 or 0, ISO 8601 strings, integers, and 'NULL' string) - Add plist_to_openstep_with_options() function to allow passing coercion option (and others) - Update plist_write_to_string() and plist_write_to_stream() accordingly

2026-02-25xplist: Enforce single root value inside <plist>Gravatar Sami Kortelainen5-17/+203
Ensure that XML property lists contain exactly one root value inside the <plist> element and reject any additional value nodes before </plist>. Add tests covering root value handling and nested CF$UID conversion behavior. Co-authored-by: Sami Kortelainen <sami.kortelainen@piceasoft.com> Co-authored-by: Nikias Bassen <nikias@gmx.li>
2026-02-22xplist: Convert nested {CF$UID:<int>} dicts to PLIST_UID safelyGravatar Sami Kortelainen2-32/+100
Convert single-entry { "CF$UID" : <integer> } dictionaries to PLIST_UID nodes when closing a dict in the XML parser. Refactor node cleanup logic: - Split plist_free_data() into internal _plist_free_data() - Introduce plist_free_children() to release child nodes separately - Update plist_set_element_val() to free children before changing container node types - Ensure PLIST_DICT hashtables do not free values (assert + force free_func = NULL) This avoids in-place container mutation issues and ensures child nodes and container metadata are released correctly before changing node type.

2026-02-12plist: make array and dict iterators opaqueGravatar Nikias Bassen2-41/+81
Introduce private iterator structs for plist_array_iter and plist_dict_iter, and fix *_next_item() to properly advance iterator state and handle malformed containers safely.

2026-02-10plist: Make plist copy and free implementations iterativeGravatar Nikias Bassen2-48/+211
Convert plist_free_node() and plist_copy_node() to iterative implementations. This avoids unbounded recursion and stack overflow when handling deeply nested plist data, while preserving existing semantics and caches.
2026-02-08plist: Handle node_attach/node_insert failuresGravatar Nikias Bassen1-43/+154
Update plist array and dict mutation helpers to check return values from node_attach() and node_insert(). This prevents cache corruption and allows new depth and cycle checks to be enforced correctly.
2026-02-08libcnary: Fix node_detach to fully clear parent relationshipGravatar Nikias Bassen1-1/+7
Ensure node_detach() clears child->parent after removal and handles missing children lists safely. This makes detached nodes reusable and allows correct rollback when reinserting nodes after failed inserts (e.g. depth-limit failures). Without this, detached nodes could remain logically parented, causing inconsistent state and preventing reinsertion.

2026-01-29xplist: Improve robustness of XML text parsing and value conversionGravatar Nikias Bassen2-72/+155
This change adds stricter validation for numeric and date nodes, including full-input consumption, overflow/range checks, and rejection of invalid floating-point values. Whitespace handling is clarified by explicitly trimming trailing XML whitespace for value nodes.

This removes the necessity for malloc failures and reduces overhead

2026-01-21jsmn: use size_t for token offsets and harden against overflowGravatar Nikias Bassen3-25/+59
Use size_t for token start/end offsets instead of int, replace the -1 sentinel with SIZE_MAX, and add a defensive guard against offset wraparound. This prevents overflow when parsing very large JSON inputs. This addresses issue #282. Credit to @ylwango613 for repporting.
2026-01-20plist: Fix heap overflow caused by incorrect PLIST_STRING length during copyGravatar Nikias Bassen1-3/+18
Credit to @LkkkLxy. Addresses #277.
2026-01-20plist: Reject insertion of plist nodes that already have a parentGravatar Nikias Bassen1-57/+74
Credit to @LkkkLxy for reporting (#276). libplist nodes are owned by exactly one container. Inserting the same plist_t into multiple dicts or arrays corrupts the tree structure and leads to use-after-free crashes during traversal or plist_free(). Add explicit parent checks to dict and array insertion APIs to reject nodes that already belong to another container. In debug builds, this fails loudly via assert() and optional diagnostics; in release builds, the operation safely no-ops. Callers that need to reuse values must create a copy using plist_copy() or explicitly detach the node before reinserting it.
