| Description: |
| This library is used to decompress and analyze .RAR and other related files that |
| have been downloaded by the user to check their Safe Browsing reputation. It is |
| only for Chromium on desktop. |
| |
| Warning: |
| Please note that changes have been made to this library to terminate the current |
| process in which this library is running, when it encounters some error |
| conditions. This is acceptable for Chromium because the library executes inside |
| a sandbox, but may not apply more broadly. |
| |
| Notable changes from upstream: |
| - Use CHROMIUM_UNRAR macro to guard Chromium-specific changes. |
| - Rewrite WinNT() in isnt.cpp to use the new Windows APIs. |
| - Replace exceptions with terminating the current process. Guarded with the |
| macro UNRAR_NO_EXCEPTIONS. |
| - Pass a file handle to the rar file, instead of trying to open the rar file |
| inside the unrar library code. This is done because the unrar library code |
| operates inside a sandbox, so it doesn't have the permissions to open files. |
| - Remove some static initializers. |
| - Pass a file handle to a temporary file with write permission, so the archive |
| can be extracted inside the sandbox for analysis. |
| - Fix a bug with NOVOLUME implementation (https://crbug.com/949787). This |
| should be temporary, until the fix can be pulled from upstream. |
| - More static initializers removed. |
| - Changes to support building in -std=c++20 mode. |
| - Cherry-picked https://github.com/aawc/unrar/pull/35 |
| - Fix alignment errors reported by UBSan by disabling ALLOW_MISALIGNED. |
| - Fix unportable include name. |
| - Replace functions that call user32.dll and gdi32.dll on Windows, to avoid |
| loading them under win32k lockdown sandbox. |
| |
| All these changes are included in one patch file (chromium_changes.patch) |
