test: split test-largefile.t in multiple file The `test-largefiles.t` unified test is significantly longer (about 30%) than any other tests in the mercurial test suite. As a result, its is alway the last test my test runner is waiting for at the end of a run. In practice, this means that `test-largefile.t` is wasting half a minute of my life every times I'm running the mercurial test suites. This probably mean more a few cumulated day by now. I've finally decided to split it up in multiple smaller tests to bring it back in reasonable length. This changeset extracts independent test cases in two files. One dedicated to wire protocole testing, and another one dedicated to all other tests that could be independently extracted. No test case were haltered in the making of this changeset. Various timing available below. All timing have been done on a with 90 jobs on a 64 cores machine. Similar result are shown on firefly (20 jobs on 12 core). General timing of the whole run -------------------------------- We see a 25% real time improvement for no significant cpu time impact. Before split: real 2m1.149s user 58m4.662s sys 11m28.563s After split: real 1m31.977s user 57m45.993s sys 11m33.634s Last test to finish (using run-test.py --time) ---------------------------------------------- test-largefile.t is now finishing at the same time than other slow tests. Before split: Time Test 119.280 test-largefiles.t 93.995 test-mq.t 89.897 test-subrepo.t 86.920 test-glog.t 85.508 test-rename-merge2.t 83.594 test-revset.t 79.824 test-keyword.t 78.077 test-mq-header-date.t After split: Time Test 90.414 test-mq.t 88.594 test-largefiles.t 85.363 test-subrepo.t 81.059 test-glog.t 78.927 test-rename-merge2.t 78.021 test-revset.t 77.777 test-command-template.t Timing of largefile test themself ----------------------------------- Running only tests prefixed with "test-largefiles". No significant change in cumulated time. Before: Time Test 58.673 test-largefiles.t 2.931 test-largefiles-cache.t 0.583 test-largefiles-small-disk.t After: Time Test 31.754 test-largefiles.t 17.460 test-largefiles-misc.t 8.888 test-largefiles-wireproto.t 2.864 test-largefiles-cache.t 0.580 test-largefiles-small-disk.t

mq: use the editor gotten by "getcommiteditor()" instead of "ui.edit()" (qrefresh/qfold) This patch also replaces "editor = False" by "editor = cmdutil.getcommiteditor()", because: - it allows to hook commit message determination easily, even in the case without "--edit" - it avoids regression (or additional care) around saving "last-message.txt", even if MQ's "newcommit()" changes its implementation logic from "localrepository.commit" to "localrepository.commitctx" with "memctx" in the future to save commit message into "last-messge.txt" with "memctx", "editor" should be valid function.

mq: fold the code paths to invoke editor into specific logic (qrefresh/qfold) This factoring simplifies the succeeding patch to switch from "ui.edit()" to "getcommiteditor()" for qrefresh/qfold.

mq: use the editor gotten by "getcommiteditor()" instead of "ui.edit()" (qnew) This patch also replaces "editor = False" by "editor = cmdutil.getcommiteditor()", because: - the latter allows to hook commit message determination easily, even in the case without "--edit" - the latter can avoid regression (or additional care) around saving "last-message.txt", even if MQ's "newcommit()" changes its implementation logic from "localrepository.commit" to "localrepository.commitctx" with "memctx" in the future to save commit message into "last-messge.txt" with "memctx", "editor" should be valid function.

mq: fold the code path to invoke editor into specific logic (qnew) This factoring simplifies the succeeding patch to switch from "ui.edit()" to "getcommiteditor()" for qnew.

cmdutil: enhance "getcommiteditor()" for specific usages in MQ This patch introduces "finishdesc" and "extramsg" arguments into "getcommiteditor()" for specific usages in MQ. "finishdesc" will be used to treat the commit message as "[mq]; patch-file-name" (default MQ commit message), if it is left as empty, instead of aborting commit process. "extramsg" will be used to show the line below: HG: Leave message empty to use default message instead of: HG: Leave message empty to abort commit
