branch name caching We rev branch cache is updated automatically. In these tests we use a trick to trigger rebuilds. We remove the branch head cache and run 'hg head' to cause a rebuild that also will populate the rev branch cache. revision branch cache is created when building the branch head cache $ rm -rf .hg/cache; hg head a -T '{rev}\n' 5 $ f --hexdump --size .hg/cache/rbc-* .hg/cache/rbc-names-v1: size=92 0000: 64 65 66 61 75 6c 74 00 61 00 62 00 63 00 61 20 |default.a.b.c.a | 0010: 62 72 61 6e 63 68 20 6e 61 6d 65 20 6d 75 63 68 |branch name much| 0020: 20 6c 6f 6e 67 65 72 20 74 68 61 6e 20 74 68 65 | longer than the| 0030: 20 64 65 66 61 75 6c 74 20 6a 75 73 74 69 66 69 | default justifi| 0040: 63 61 74 69 6f 6e 20 75 73 65 64 20 62 79 20 62 |cation used by b| 0050: 72 61 6e 63 68 65 73 00 6d 00 6d 64 |ranches.m.md| .hg/cache/rbc-revs-v1: size=160 0000: 19 70 9c 5a 00 00 00 00 dd 6b 44 0d 00 00 00 01 |.p.Z.....kD.....| 0010: 88 1f e2 b9 00 00 00 01 ac 22 03 33 00 00 00 02 |.........".3....| 0020: ae e3 9c d1 00 00 00 02 d8 cb c6 1d 00 00 00 01 |................| 0030: 58 97 36 a2 00 00 00 03 10 ff 58 95 00 00 00 04 |X.6.......X.....| 0040: ee bb 94 44 00 00 00 02 5f 40 61 bb 00 00 00 02 |...D...._@a.....| 0050: bf be 84 1b 00 00 00 02 d3 f1 63 45 80 00 00 02 |..........cE....| 0060: e3 d4 9c 05 80 00 00 02 e2 3b 55 05 00 00 00 02 |.........;U.....| 0070: f8 94 c2 56 80 00 00 03 f3 44 76 37 00 00 00 05 |...V.....Dv7....| 0080: a5 8c a5 d3 00 00 00 05 df 34 3b 0d 00 00 00 05 |.........4;.....| 0090: c9 14 c9 9f 00 00 00 06 cd 21 a8 0b 80 00 00 05 |.........!......| no errors when revbranchcache is not writable $ echo >> .hg/cache/rbc-revs-v1 $ mv .hg/cache/rbc-revs-v1 .hg/cache/rbc-revs-v1_ $ mkdir .hg/cache/rbc-revs-v1 $ rm -f .hg/cache/branch* && hg head a -T '{rev}\n' 5 $ rmdir .hg/cache/rbc-revs-v1 $ mv .hg/cache/rbc-revs-v1_ .hg/cache/rbc-revs-v1 no errors when wlock cannot be acquired #if unix-permissions $ mv .hg/cache/rbc-revs-v1 .hg/cache/rbc-revs-v1_ $ rm -f .hg/cache/branch* $ chmod 555 .hg $ hg head a -T '{rev}\n' 5 $ chmod 755 .hg $ mv .hg/cache/rbc-revs-v1_ .hg/cache/rbc-revs-v1 #endif recovery from invalid cache revs file with trailing data $ echo >> .hg/cache/rbc-revs-v1 $ rm -f .hg/cache/branch* && hg head a -T '{rev}\n' --debug 5 truncating cache/rbc-revs-v1 to 160 $ f --size .hg/cache/rbc-revs* .hg/cache/rbc-revs-v1: size=160 recovery from invalid cache file with partial last record $ mv .hg/cache/rbc-revs-v1 . $ f -qDB 119 rbc-revs-v1 > .hg/cache/rbc-revs-v1 $ f --size .hg/cache/rbc-revs* .hg/cache/rbc-revs-v1: size=119 $ rm -f .hg/cache/branch* && hg head a -T '{rev}\n' --debug 5 truncating cache/rbc-revs-v1 to 112 $ f --size .hg/cache/rbc-revs* .hg/cache/rbc-revs-v1: size=160 recovery from invalid cache file with missing record -
