| 6 """Archives or replays webpages and creates SKPs in a Google Storage location. |
| 7 |
| 8 To archive webpages and store SKP files (archives should be rarely updated): |
| 9 |
| 10 cd ../buildbot/slave/skia_slave_scripts |
| 11 python webpages_playback.py --dest_gsbase=gs://rmistry --record \ |
| 12 --page_sets=all --skia_tools=/home/default/trunk/out/Debug/ \ |
| 13 --browser_executable=/tmp/chromium/out/Release/chrome |
| 14 |
| 15 |
| 16 To replay archived webpages and re-generate SKP files (should be run whenever |
| 17 SkPicture.PICTURE_VERSION changes): |
| 18 |
| 19 cd ../buildbot/slave/skia_slave_scripts |
| 20 python webpages_playback.py --dest_gsbase=gs://rmistry \ |
| 21 --page_sets=all --skia_tools=/home/default/trunk/out/Debug/ \ |
| 22 --browser_executable=/tmp/chromium/out/Release/chrome |
| 23 |
| 24 |
| 25 Specify the --page_sets flag (default value is 'all') to pick a list of which |
| 26 webpages should be archived and/or replayed. Eg: |
| 27 |
| 28 --page_sets=page_sets/skia_yahooanswers_desktop.json,\ |
| 29 page_sets/skia_wikipedia_galaxynexus.json |
| 30 |
| 31 The --browser_executable flag should point to the browser binary you want to use |
| 32 to capture archives and/or capture SKP files. Majority of the time it should be |
| 33 a newly built chrome binary. |
| 34 |
| 35 The --upload_to_gs flag controls whether generated artifacts will be uploaded |
| 36 to Google Storage (default value is False if not specified). |
| 37 |
| 38 The --non-interactive flag controls whether the script will prompt the user |
| 39 (default value is False if not specified). |
| 40 |
| 41 The --skia_tools flag if specified will allow this script to run |
| 42 debugger, render_pictures, and render_pdfs on the captured |
| 43 SKP(s). The tools are run after all SKPs are succesfully captured to make sure |
| 44 they can be added to the buildbots with no breakages. |
| 45 To preview the captured SKP before proceeding to the next page_set specify both |
| 46 --skia_tools and --view_debugger_output. |
