20 | 2012-12-20 | strings | api | mesa | unknown | - | http://crbug.com/145525 | kbr: Caused by using a text-based language where there were mismatches between the shading language and API, and where compilers tried to be too clever. This was one of the early security bugs in WebGL. | ||
21 | 2012-04-19 | strings | parsing | angle | 78a351987686488741e1b972ba574b833cff2376 | link | none | Added a catch-rule for invalid numbers. | kbr: Caused by using a text-based language. Users tried to feed in numbers that exceeded value limits. | |
22 | 2012-04-13 | strings | preprocessor | angle | e63436b9ac1067efe2e83999b0bbdfe05adea4f3 | link | http://anglebug.com/178 | Handle hex int constant in preprocessor | kbr: This was an early bug in ANGLE's preprocessor. Having a "C-style" preprocessor is a disaster. Until Alok rewrote it it was a source of no end of security bugs. | |
23 | 2011-12-08 | strings | parsing | macos | none | - | http://crbug.com/90495 | none | kbr: Early bug caused by drivers using old versions of 3DLabs' compiler which didn't have all the bug fixes we ultimately put into ANGLE. The argument here is that using a text-based language inherently relies on a lot of string processing and this is a highly error prone operation. If the language is directly ingested by the browser, there will be attempts to make the variable names as close to the original shaders' versions, and these will directly lead to these buffer overflow errors. | |
24 | 2011-04-23 | strings | parsing | angle | fd747b861195a03df634a722a9cf3505dcd41253 | link | http://anglebug.com/144 | Implement shader identifier name mapping. | kbr: Caused by using a text-based language. Found that we ultimately had to map all user identifiers to alternate names in order to reliably translate shaders. | |
25 | 2011-01-29 | strings | parsing | angle | - | http://crbug.com/70718 | kbr: Caused squarely by using a text-based language. Multi-byte Unicode character had to be filtered out before handing shader to lower-level shader compiler. | |||
26 | 2010-07-21 | strings | parsing | angle | 613ef31a9f7c6f99b064df68894e0a9ba4857025 | link | none | Added checks for webgl_ and _webgl_ reserved identifiers. This currently only checks variable and function names. Struct names and field names will be added in the another CL. | kbr: Caused by using a text-based language. Needed to reserve identifiers so we had the ability to transform the shaders. | |
27 | 2010-07-15 | strings | api | chrome | f6d33f3627cbb380773957fe14fcedc3b4087f53 | link | none | Fixed bug with the way the command buffer code handled arrays of uniforms. | kbr: Caused by using a text-based language where the API required looking up the location of each individual uniform in the shader. We have had no end of bugs like these. These classes of bugs don't exist in SPIR-V since the names are optional and only used for debugging. | |

Would not exist in SPIR-V, where there is no scoping. | |

32 | 2014-01-03 | scoping | diagnostics | angle | 44cc79f67183d9bb36a9586c1a4219448453b9ed | link | http://crbug.com/330222 | Fix compiler crash. | kbr: Bug fix to allow compilation to continue after the first parse error. This wouldn't happen if using SPIR-V since we would just reject the shader upon the first error seen. | |

35 | 2012-08-22 | limits | typing | mesa | unknown | - | http://crbug.com/141901 | kbr: Caused by using a text-based language rather than something which declared its resources up front. Workaround required parsing the shader. This was in the days before we used ANGLE's shader translator everywhere. | ||
36 | 2012-07-09 | limits | parsing | angle | c022c3affcb88e1dd5b746c5db1d171feac0f081 | link | none | WebGL spec specifies maximum length of all types of tokens - not just identifier tokens. And it also means preprocessing-tokens, not compiler tokens. | kbr: Then there was a further bug in the above (d35efdf5). | |
37 | 2012-07-03 | limits | parsing | angle | d35efdf533eb45599d2ffa9dc0e781e2366488df | link | none | Restricted the length of identifiers (including #define directive) to 256, as required by webgl spec. | kbr: This restriction was specifically added because of bugs in underlying shader compilers. Would not exist in SPIR-V since identifier names would only be in debug info. | |
