* Add additional checks for size_t overflowsDerek Mauro2024-03-141-2/+5
| | | | | | | | | This change mainly affects 32-bit platforms. Similar to 4618865caf8596742a9fd7c28a70a46b5e277794, check for size_t overflow in all places where string result sizes are precomputed before allocation. PiperOrigin-RevId: 615792028 Change-Id: I71c774c5ef2c2978bd812c70e9bab36d266b7c90
* Be more consistent in the documentation and variable declarations for base64 ↵Abseil Team2023-03-161-0/+23
| | | | | | | | | | | escaping vs unescaping: * Move table documenting escaping conversions to be next to the internal escaping code that implements it. Mention it from the internal _un_escaping code (which reverses it) too. * Centralize the two arrays which map from normal chars to escaped chars (k(WebSafe)Base64Chars), and make bidirectional documentation links between them and their reverse (unescaping) maps (kUn(WebSafe)Base64). * Remove redundant list of escaping/unescaping methods in the public escaping.cc.
