Added tag 5.2.2 for changeset b4c82b704180

py3: force bytestr conversion of "reason" in scmutil.callcatch() For instance, reason may be an InvalidURL as shown in added test.

rust-cpython: do not convert warning pattern to utf-8 bytes On Unix, both Rust Path and Mercurial expect a locale-dependent bytes, and we don't support Windows yet. Differential Revision: https://phab.mercurial-scm.org/D7614

rust-cpython: import utils::files::* function at module level IIRC, it's common in Rust to call functions with the module prefix. Differential Revision: https://phab.mercurial-scm.org/D7613

py3: send bytes from Rust-created warning patterns Python code expects bytes in both Python 2 and Python 3, so we should send bytes. Differential Revision: https://phab.mercurial-scm.org/D7612

py3: pass bytes to `configint` and `configbool` Both functions require bytes, even in Python 3. Differential Revision: https://phab.mercurial-scm.org/D7611

rust-threads: force Rayon to respect the worker count in config As per the inline comment, this is a workaround because Rust code does not yet know how to read config files. Differential Revision: https://phab.mercurial-scm.org/D7610

remotefilelog: remove the `ensurestart` usage The option does not seems to do what we want since it does not wait on the background process actually starting (eg: taking the lock). And the race have been dealt with another way anyway. This effectively back out changeset 2c74337e6483. Differential Revision: https://phab.mercurial-scm.org/D7590

remotefilelog: remove most of the debugwait* command in the tests Since we use a dedicated developer config, we do not need them anymore. Differential Revision: https://phab.mercurial-scm.org/D7589

remotefilelog: use the correct redirection in tests The test were using '2>%1' which just redirect stderr in the "%1" file. The intend was '2>&1' which redirect stderr on stdin. This impact tests because some commit were picking up this '%1' files. Differential Revision: https://phab.mercurial-scm.org/D7588

remotefilelog: remove most sleep in tests Now that we removed most of the races, we can remove the infamous sleeps. Differential Revision: https://phab.mercurial-scm.org/D7587

remotefilelog: have command wait for background task in the tests We leverage the feature introduced in the two previous commit to have the main command wait for the background task to be finished before returning. All test still pass and instability seems to have gone away. Most of the sleep and explicit wait are now useless and will be cleaned up in later changesets. Differential Revision: https://phab.mercurial-scm.org/D7586

remotefilelog: add a developer option to wait for background processes In order to block the main command on the subprocess exiting, we ensure the repo's ui object will call the subprocess.wait() method to ensure the top-level hg process doesn't exit until all background processes have also done so. Currently, in the tests, most operation spawning background process as followed by commands waiting for these operations to complete. However this waiting is racy. First because it seems like we can start waiting before the background operation actually start, in which case it is prematurely detected as "done". Second, because some commands may spawn multiple background operation for the same operation (eg: rebase can apparently trigger multiple prefetch). The current approach could be updated to maybe handle the first issue, but the second one will never be properly handled. In most case, we do not care that the bg process keep running after the command end. (Since we explicitly wait for them to end before doing anything else). So we add an option to wait on the background process before exiting the command. We'll put it in use in the next changeset. Differential Revision: https://phab.mercurial-scm.org/D7585

procutil: add a option to not fully detach background process When writing test, it is useful to make code pretending to spawn a fully detached process while still actually waiting for it to finish. We add the option to `procutil.runbgcommand`, to do so. We will use this in remote-filelog tests. Differential Revision: https://phab.mercurial-scm.org/D7584
