dirstate.status: assign members one by one instead of unpacking the tuple With this patch, hg status and hg diff regain their previous speed. The following tests are run against a working copy with over 270,000 files. Here, 'before' means without this or the previous patch applied. Note that in this case `hg perfstatus` isn't representative since it doesn't take dirstate parsing time into account. $ time hg status # best of 5 before: 2.03s user 1.25s system 99% cpu 3.290 total after: 2.01s user 1.25s system 99% cpu 3.261 total $ time hg diff # best of 5 before: 1.32s user 0.78s system 99% cpu 2.105 total after: 1.27s user 0.79s system 99% cpu 2.066 total
