| 1 Prerequisites | |
| 2 ============= | |
| 3 | |
| 4 You can use your Ubuntu box (>= 8.04. 9.10 is recommended) to test OTS library. | |
| 5 | |
| 6 First, install TrueType and OpenType fonts to the Ubuntu box as many as | |
| 7 possible. | |
| 8 | |
| 9 % sudo apt-get install ttf-.*[^0]$ | |
| 10 | |
| 11 Then, put malicious TrueType fonts on `~/malicious/`. For details, please check | |
| 12 http://code.google.com/p/chromium/issues/detail?id=27139#c2. Currently access | |
| 13 to the issue is limited to chromium-security team members for security reasons. | |
| 14 | |
| 15 % cd | |
| 16 % tar xjf ~/ttf-testsuite.tar.bz2 | |
| 17 | |
| 18 Test | |
| 19 ==== | |
| 20 | |
| 21 In order to verify that: | |
| 22 | |
| 23 1. OTS does not reject these unmalicious fonts. | |
| 24 2. and transcoded fonts OTS generates can be loaded by a system font renderer (F
reeType2). | |
| 25 | |
| 26 Run `test_unmalicious_fonts.sh` script: | |
| 27 | |
| 28 % cd /path/to/ots/tests | |
| 29 % ./test_unmalicious_fonts.sh | |
| 30 ............................................... (verify that no FAIL: is di
splayed) | |
| 31 | |
| 32 Then in order to verify that: | |
| 33 | |
| 34 1. OTS can reject malicious fonts | |
| 35 2. or transcoded fonts generated by OTS do not crash a system font renderer (Fre
eType2). | |
| 36 | |
| 37 Run `test_malicious_fonts.sh` script: | |
| 38 | |
| 39 % cd /path/to/ots/tests | |
| 40 % ./test_malicious_fonts.sh | |
| 41 ............................................... (verify that no FAIL: is di
splayed) | |
| 42 | |
| 43 Command line tools | |
| 44 ================== | |
| 45 | |
| 46 We have some command line tools for tests. To build them: | |
| 47 | |
| 48 - On Linux: | |
| 49 | |
| 50 % gyp --depth=. -f make ots-standalone.gyp | |
| 51 % make | |
| 52 (tool is located at build/Default directory) | |
| 53 | |
| 54 - On Windows (VC++ is needed): | |
| 55 | |
| 56 % gyp --depth=. -f msvs ots-standalone.gyp | |
| 57 % devenv.exe /build Default ots-standalone.sln /project idempotent.vcpro
j | |
| 58 (tool is located at Default directory) | |
| 59 | |
| 60 - On Mac (XCode is needed): | |
| 61 | |
| 62 % gyp --depth=. -f xcode ots-standalone.gyp | |
| 63 % xcodebuild -configuration Default -project ots-standalone.xcodeproj -t
arget All | |
| 64 (tool is located at build/Default directory) | |
| 65 | |
| 66 You can use `idempotent` tool to check whether a font will be rejected or not. | |
| 67 You can also use `ot-sanitise` tool to get sanitised font (it is available on | |
| 68 Linux for now). See README file in the test directory for more details. | |
