fix: fix registration of config item defaults Before this patch, because of the "(:<name>)?", all registered patterns would match and the default value would not be the one we thought we had registered (maybe it just took the default value for the first match?). This didn't matter because we didn't care about the default value; we used our own, intended default value in getfixers() anyway. We also have to look up each config item individually in order to not get developer warnings. Differential Revision: https://phab.mercurial-scm.org/D7082

rust-cpython: drop direct dependency on python(27|3)_sys We no longer use it.

rust-cpython: leverage upstreamed py_capsule_fn!() macro

rust-cpython: bump cpython crates to 0.3 Unblocks py_capsule_fn!().

rust-cpython: turn inline comments into non-doc comments

rust-cpython: fix signature of make_dirstate_tuple() Fortunately, the layout of PyObject {} is compatible with a C pointer, but we shouldn't rely on that. This also fixes the handling of NULL pointer.

rust-cpython: mark capsule function as unsafe

rust-cpython: add wrapper around decapsule_make_dirstate_tuple() There are a couple of safety issues. First, the returned function pointer must be unsafe. Second, its return value must be a raw pointer (i.e. python27_sys::PyObject), not a cpython::PyObject. The wrapper function will address these issues.

eol: don't fallback to use .hgeol from tip (BC) If no .hgeol were found in the current working directory, eol would fallback to use the one in tip. That could in some cases give very confusing or wrong behaviour when it applied wrong filters. It might be convenient to have plain 'clone' immediately apply 'native' encoding patterns in the cloned repo. But it is wrong to assume that this revision is tip, and even more wrong to also apply it when not cloning - for example when updating between history revisions. The encoding should always match the content of the current .hgeol . It should never use anything else.

eol: tweak test-eol-clone.t with better descriptions and logging Expose impact of changes coming next ...

eol: fix update - don't use and apply removed .hgeol patterns 'hg up -C' to revisions with different .hgeol patterns could leave dirty changes in the working directory. That could make deployment of new .hgeol filters tricky: they would "occasionally" apply also in branches where they shouldn't. Fixed by dropping all old patterns before applying new ones.

eol: cache needs update, also if it has same timestamp as the source Ignoring same timestamp could (in theory?) cause changes to not be detected. It might happen quite often that the cache is populated right after .hgeol has been updated and they thus have the same time stamp second. But we want correctness, and if it populates the cache so fast, then it can also not be a big problem to run it again next time when the timestamp has moved on.

eol: update isbinary filter to work without compat wrapper

localrepo: fix variable binding in handling of old filters The lambda was referencing oldfn in outer scope without binding the current value. If oldfn function were reassigned before use, wrong filters could be used. Fixed by having oldfn as named parameter default value of the lambda.

localrepo: debug log of filter name when filtering through a function

eol: test-eol-update.t coverage around update --clean using filters ... badly This will reveal problems and track their fixes.

copies: drop the findlimit logic We don't use the limit anymore so we should stop computing that limit. I did not bother measuring the potential performance gain. I am assuming that not running any code will be faster that doing some computation and not using the result.

pathcopies: give up any optimization based on `introrev` Between 8a0136f69027 and d98fb3f42f33, we sped up the search for the introduction revision during path copies. However, further checking show that finding the introduction revision is still expensive and that we are better off without it. So we simply drop it and only rely on the linkrev optimisation. I ran `perfpathcopies` on 6989 pair of revision in the pypy repository (`hg perfhelper-pathcopies`. The result is massively in favor of dropping this condition. The result of the copy tracing are unchanged. Attempt to use a smaller changes preserving linkrev usage were unsuccessful, it can return wrong result. The following changesets broke test-mv-cp-st-diff.t - if not f.isintroducedafter(limit): + if limit >= 0 and f.linkrev() < limit: return None Here are various numbers (before this changeset/after this changesets) source destination before after saved-time ratio worth cases e66f24650daf 695dfb0f493b 1.062843 1.246369 -0.183526 1.172675 c979853a3b6a 8d60fe293e79 1.036985 1.196414 -0.159429 1.153743 22349fa2fc33 fbb1c9fd86c0 0.879926 1.038682 -0.158756 1.180420 682b98f3e672 a4878080a536 0.909952 1.063801 -0.153849 1.169074 5adabc9b9848 920958a93997 0.993622 1.147452 -0.153830 1.154817 worse 1% dbfbfcf077e9 aea8f2fd3593 1.016595 1.082999 -0.066404 1.065320 worse 5% c95f1ced15f2 7d29d5e39734 0.453694 0.471156 -0.017462 1.038488 worse 10% 3e144ed1d5b7 2aef0e942480 0.035140 0.037535 -0.002395 1.068156 worse 25% 321fc60db035 801748ba582a 0.009267 0.009325 -0.000058 1.006259 median 2088ce763fc2 e6991321d78b 0.000665 0.000651 0.000014 0.978947 best 25% 915631a97de6 385b31354be6 0.040743 0.040363 0.000380 0.990673 best 10% ad495c36a765 19c10384d3e7 0.431658 0.411490 0.020168 0.953278 best 5% d13ae7d283ae 813c99f810ac 1.141404 1.075346 0.066058 0.942126 best 1% 81593cb4a496 99ae11866969 1.833297 0.063823 1.769474 0.034813 best cases c3b14617fbd7 743a0fcaa4eb 1101.811740 2.735970 1099.075770 0.002483 c3b14617fbd7 9ba6ab77fd29 1116.753953 2.800729 1113.953224 0.002508 058b99d6e81f 57e249b7a3ea 1246.128485 3.042762 1243.085723 0.002442 9a8c361aab49 0354a250d371 1253.111894 3.085796 1250.026098 0.002463 442dbbc53c68 3ec1002a818c 1261.786294 3.138607 1258.647687 0.002487 As one can see, the average case is not really impacted.

phabricator: add addremoved and addmodified functions These are relatively simple so add them together. As the name indicates, these add phabchange objects for removed and modified files to the phabdiff. Differential Revision: https://phab.mercurial-scm.org/D7049

phabricator: add the uploadfile function This is needed to be able to submit binary files such as images in commits (and also non-UTF-8 text files). One of the primary disadvantages of the current use of createrawdiff is that Phabricator simply drops any binary diffs included in the patch, but not the files, so if such a diff is then committed it corrupts any binary files in it.
