relnotes: enable extension when running releasenotes command Last night, when I was working on different machine, the test worked, now on a different machine it does not. Looks like we should make sure releasenotes extension is loaded. Differential Revision: https://phab.mercurial-scm.org/D4425

narrow: rename getbundlechangegrouppart_nonellipsis function The function is renamed to getbundlechangegrouppart_widen as per suggestion in D4383. The motivation is such that we can evolve the function into a handler for new wire-protocol command. Differential Revision: https://phab.mercurial-scm.org/D4424

tests: rename test-narrow-widen-non-ellipsis to match current names The test is renamed to test-narrow-widen-no-ellipsis (note non -> no), to match with test-narrow-clone-no-ellipsis.t. Follows up on D4382. Differential Revision: https://phab.mercurial-scm.org/D4423

contrib: byteify perf.py file This is done using contrib/byteify-strings.py. There is just one extra change done to make sure lines don't get longer than 80 chars. # skip-blame because just b'' prefixes. Differential Revision: https://phab.mercurial-scm.org/D4422

tests: use {rev} instead of {node|short} and (glob) in narrow tests I think we used {node|short} because they were first written for only flat manifests and we didn't think to change the format when we started testing tree manifests. Differential Revision: https://phab.mercurial-scm.org/D4421

shortest: fix an off-by-1 when disambiguating against revnums Revision "5" is an unambiguous hex prefix in a repo with 5 revisions; it's only "4" and lower that are ambiguous. Differential Revision: https://phab.mercurial-scm.org/D4420

filemerge: fix an i18n comment typo

tests: add flat manifest case in test-narrow-widen-non-ellipsis.t We had this test with tree manifest only because the tests were broken and we were fixing them and maintaing two different cases of broken tests was bit hard. Now that things work fine, let's add the flat manifest case. The test shows that things work fine in both cases. Differential Revision: https://phab.mercurial-scm.org/D4385

narrow: update the narrowspecs to new ones after pulling when widening The ellipsis case updates the new narrowspecs at bundle2 handling code, and non-ellipsis widening didn't use to work and never set the new narrowpats. Previous pacth added server side logic for widening without ellipsis. This patch adds the missing repo.setnarrowpats() so that we set the new narrowpats after widening in non-ellipsis cases also. This makes widening with non-ellipsis case work but there are certain things which we can improve. Differential Revision: https://phab.mercurial-scm.org/D4384

narrow: add server logic to send cg while widening without ellipsis Before this patch, if you try to widen a narrow clone without ellipsis enabled, it will be broken and the exchange.pull() done by tracked command to widen the clone will be no-op because no custom logic exists for this and server sees that we have all csets and it says `no changes found`. The widening with ellipsis send KILL for existing changegroups and send new changegroups because of the change in ellipsis hash, but we can prevent that in non-ellipsis cases. This patch adds server side logic to send the changegroups for the changesets which are on the client again with filelogs and manifests for the new includes. This is a very starting implementation and we send changegroups and manifests too while we can prevent them. Following things can definitely be improved in the logic this patch adds: 1) Send just the filelogs and treemanifests 2) Send the filelogs only for the additions in the include I tried 1) here but the code is coupled tightly and the way I was able to do that was hacking into the changegroup generation code in a very dirty way, like adding conditionals and preventing the yield. This patch also adds a 'widen' kwarg to prevent other commands except widening to go through that codepath. The test changes demonstrate that the new implementation is correct and fixes things.
