heptapod-ci: run the --pure test too These are usually rarely run by individual developper because they are slow. However it is important that they stay happy. Differential Revision: https://phab.mercurial-scm.org/D8016

heptapod-ci: run the normal test suite The usual tests should be run too. We skip the "tests-check*.t" one because their are already covered by another Ci step. Differential Revision: https://phab.mercurial-scm.org/D8015

heptapod-ci: also run the dedicated rust test for the rust code The Rust code has various standard rust test that are fast to run. So let's run them. Differential Revision: https://phab.mercurial-scm.org/D8014

heptapod-ci: run test with python3 too Python3 is the future^W present, it is important to run tests with it too. Differential Revision: https://phab.mercurial-scm.org/D8013

heptapod-ci: colorize output The run result are nicer to read with color. Differential Revision: https://phab.mercurial-scm.org/D8012

heptapod-ci: add a basic file to be able to run tests with heptapod Having this yaml file somewhere in the main mercurial repository makes it trivial for contributors using heptapod to run CI on their in-progress work. There are alot of different combination (python2/python3 pure/cext/rust/pypy) to be tested and making sure all of them are covered manually is cumbersome. Automatic CI runnig on draft really helps in that matters. We start small bu later changesets will add more step testing more of the variants. The series is targetted on stable to make it available to the widest amount of contribution possible. The definition of the docker files used for this are available here: https://dev.heptapod.net/octobus/ci-dockerfiles Differential Revision: https://phab.mercurial-scm.org/D8011

worker: manually buffer reads from pickle stream My previous fix (D8051, cb52e619c99e, which added Python's built-in buffering to the pickle stream) has the problem that the selector will ignore the buffer. When multiple pickled objects are read from the pipe into the buffer at once, only one object will be loaded. This can repeat until the buffer is full and delays the processing of completed items until the worker exits, at which point the pipe is always considered readable and all remaining items are processed. This changeset reverts D8051, removing the buffer again. Instead, on Python 3 only, we use a wrapper to modify the "read" provided to the Unpickler to behave more like a buffered read. We never read more bytes from the pipe than the Unpickler requests, so the selector behaves as expected. Also add a test case for "pickle data was truncated" issue. https://phab.mercurial-scm.org/D8051#119193 Differential Revision: https://phab.mercurial-scm.org/D8076

config: also respect HGRCSKIPREPO in the zeroconf extension Differential Revision: https://phab.mercurial-scm.org/D8075

config: also respect HGRCSKIPREPO in hgwebdir_mod Differential Revision: https://phab.mercurial-scm.org/D8074

config: also respect HGRCSKIPREPO in `dispatch._getlocal` For some reason, we are also reading the local config in that function. Differential Revision: https://phab.mercurial-scm.org/D8073

config: add a function in `rcutil` to abstract HGRCSKIPREPO We wil need to respect this environment variable in more place. Differential Revision: https://phab.mercurial-scm.org/D8072
