Hi, Based on recent issues about UDF since the code was pushed for https://lists.01.org/pipermail/edk2-devel/2017-September/014360.html, I want to raise some questions kindly.
https://lists.01.org/pipermail/edk2-devel/2017-September/014409.html https://lists.01.org/pipermail/edk2-devel/2017-September/014518.html https://lists.01.org/pipermail/edk2-devel/2017-September/014542.html https://lists.01.org/pipermail/edk2-devel/2017-September/014489.html https://lists.01.org/pipermail/edk2-devel/2017-September/014551.html https://lists.01.org/pipermail/edk2-devel/2017-September/014560.html https://lists.01.org/pipermail/edk2-devel/2017-September/014649.html https://lists.01.org/pipermail/edk2-devel/2017-September/014694.html https://lists.01.org/pipermail/edk2-devel/2017-September/014695.html Is the code expected to be got upstream originally? (I may be a stupid question since the code has been gotten upstream, I just want to double confirm that as Paulo's reply below "I believed that it would never get upstream".) Is the code ready to be in master? Should it be in Staging branch first? Paulo, Could you help do more evaluation to the code as you said "I *do* know that the code really needs refactoring, documentation, etc"? I believe you are most familiar with the code and know its quality. :) BTW: More test seems need to be done before the code check in, for example, build with various tool chains, ECC scan for coding style, static tool scan, etc. That is what we(especially me) need to improve in future when developing and reviewing. Anyway, let's help keep improving UDF codes.

Nope. When doing my tests, I briefly looked at code how it's used and also added an ASSERT() to make sure it is never lesser than FilePosition. BTW, I *do* know that the code really needs refactoring, documentation, etc. -- I didnt do that before because I believed that it would never get upstream -- since its now -- I will look forward to that in my free time. Its 2:46am here so I should get some sleep :-) Thanks!
