publishing: unconditionally trust publishing flag Unfortunately, there are currently no tests for this behavior because we lack a good way of testing trust.

publishing: use new helper method

publishing: add helper method to localrepo

revset: make use of natively-computed set for 'draft()' and 'secret()' If the computation of a set for each phase (done in C) is available, we use it directly instead of applying a simple filter. This give a massive speed-up in the vast majority of cases. On my mercurial repo with about 15000 out of 40000 draft changesets: revset: draft() plain min first last 0) 0.011201 0.019950 0.009844 0.000074 1) 0.000284 2% 0.000312 1% 0.000314 3% 0.000315 x4.3 Bad performance for "last" come from the handling of the 15000 elements set (memory allocation, filtering hidden changesets (99% of it) etc. compared to applying the filter only on a handfuld of revisions (the first draft changesets being close of tip). This is not seen as an issue since: * Timing is still pretty good and in line with all the other one, * Current user of Vanilla Mercurial will not have 1/3 of their repo draft, This bad effect disappears when phase's set is smaller. (about 200 secrets): revset: secret() plain min first last 0) 0.011181 0.022228 0.010851 0.000452 1) 0.000058 0% 0.000084 0% 0.000087 0% 0.000087 19%

revset: refactor the non-public phase code Code for draft and secret are the same. We'll make it more complex to take advantages of the set recomputed in C, so we first refactor the code to only have one place to update (and make sure all behave properly). We do not refactor the 'public()' code because it does not have a natively computed set.

revset: translate node directly with changelog in 'head' Using 'repo[X]' is much slower because it creates a 'changectx' object and goes though multiple layers of code to do so. It is also error prone if there is tags, bookmarks, branch or other names that could map to a node hash and take precedence (user are wicked). This provides a significant performance boost on repository with a lot of heads. Benchmark result for a repo with 1181 heads. revset: head() plain min last reverse 0) 0.014853 0.014371 0.014350 0.015161 1) 0.001402 9% 0.000975 6% 0.000874 6% 0.001415 9% revset: head() - public() plain min last reverse 0) 0.015121 0.014420 0.014560 0.015028 1) 0.001674 11% 0.001109 7% 0.000980 6% 0.001693 11% revset: draft() and head() plain min last reverse 0) 0.015976 0.014490 0.014214 0.015892 1) 0.002335 14% 0.001018 7% 0.000887 6% 0.002340 14% The speed up is visible even when other more costly revset are in use revset: head() and author("mpm") plain min last reverse 0) 0.105419 0.090046 0.017169 0.108180 1) 0.090721 86% 0.077602 86% 0.003556 20% 0.093324 86%
