packaging: rename hgrc.d to defaultrc for Windows config files next to the exe The code and the help still says that it will read hgrc.d next to the executable. But this directory needs to exist to read the resource based config files. Otherwise even `hg version` errors out: $ /c/Program\ Files/Mercurial/hg.exe version Traceback (most recent call last): File "hg", line 43, in <module> File "mercurial\dispatch.pyc", line 110, in run File "mercurial\dispatch.pyc", line 226, in dispatch File "mercurial\ui.pyc", line 308, in load File "mercurial\rcutil.pyc", line 99, in rccomponents File "mercurial\rcutil.pyc", line 69, in default_rc_resources File "mercurial\utils\resourceutil.pyc", line 84, in contents WindowsError: [Error 3] The system cannot find the path specified: 'c:\\Program Files\\mercurial\\defaultrc\\*.*' Differential Revision: https://phab.mercurial-scm.org/D7981

merge: don't call update hook when using in-memory context I'm pretty sure many hook implementors will assume that they can inspect the working copy and/or dirstate parents when the hook is called, so I don't think we should call the hook when using an in-memory context. The new behavior matches that of the preupdate hook. Differential Revision: https://phab.mercurial-scm.org/D7898

python-zstandard: blacken at 80 characters I made this change upstream and it will make it into the next release of python-zstandard.

tests: move non-collapse test out of test-rebase-collapse The test case was added in 76630fbbf4fa (test-rebase-collapse: Add test for rebase regression introduced in 12309c09d19a, 2012-01-23). I think `hg rebase --collapse` was involved in either the regression or in the fix that caused the regression, but the test that was added doesn't use `--collapse`, so it doesn't seem to belong in test-rebase-collapse.t. The test case is about copies, so I moved it to test-rebase-rename.t. Differential Revision: https://phab.mercurial-scm.org/D7968

rust-node: binary Node ID and conversion utilities The choice of type makes sure that a `Node` has the exact wanted size. We'll use a different type for prefixes. Added dependency: hexadecimal conversion relies on the `hex` crate. The fact that sooner or later Mercurial is going to need to change its hash sizes has been taken strongly in consideration: - the hash length is a constant, but that is not directly exposed to callers. Changing the value of that constant is the only thing to do to change the hash length (even in unit tests) - the code could be adapted to support several sizes of hashes, if that turned out to be useful. To that effect, only the size of a given `Node` is exposed in the public API. - callers not involved in initial computation, I/O and FFI are able to operate without a priori assumptions on the hash size. The traits `FromHex` and `ToHex` have not been directly implemented, so that the doc-comments explaining these restrictions would stay really visible in `cargo doc` Differential Revision: https://phab.mercurial-scm.org/D7788

rust-nodemap: building blocks for nodetree structures This is similar to `nodetreenode` in `revlog.c`. We give it a higher level feeling for ease of handling in Rust context and provide tools for tests and debugging. The encoding choice is dictated by our ultimate goal in this series, that is to make an append-only persistent version of `nodetree`: the 0th Block must be adressed from other Blocks.

lfs: move the initialization of the upload request into the try block This (almost) guarantees that the file is closed in the case of an exception. The one hole is if the `seek(SEEK_END)`/`tell()`/`seek(0)` sequence fails. But that's going to go away when subclassing `httpconnection.httpsendfile` to fix the worker problem, so I'm not going to worry too much. (And that class appears to have the same problem.)

lfs: drop an unnecessary r'' prefix No longer necessary since the source transformer was removed. # skip-blame for changing string prefixes Differential Revision: https://phab.mercurial-scm.org/D7958

lfs: explicitly close the file handle for the blob being uploaded The previous code relied on reading the blob fully to close it. The obvious problem is if an error occurs before that point. But there is also a problem when using workers where the data may need to be re-read, which can't happen once it is closed. This eliminates the surprising behavior before attempting to fix the worker problem. Differential Revision: https://phab.mercurial-scm.org/D7957

lfs: drop the unused progressbar code in the `filewithprogress` class This has been unused since f98fac24b757, which added worker based transfers for concurrency, shifting the progressbar maintenance to the single thread waiting on the worker to complete. Since the name no longer fits, rename the class. Differential Revision: https://phab.mercurial-scm.org/D7956

rust-utils: add Rust implementation of Python's "os.path.splitdrive" I also wrote the NT version although I didn't mean to at first, so I thought I would keep it, so that any further effort to get the Rust code working on Windows is a little easier.

cext: change two more vars to Py_ssize_t in manifest.c D7913 fixed a compiler warning with a signedness conflict in a ternary operator by changing the types of some variables to be Py_ssize_t instead of size_t or int. That commit missed these two cases since they aren't warned about (at least on my compiler). Both of these variables are produced by operations on variables that are themselves Py_ssize_t now/already, so they should keep the same type.

phabricator: use .arcconfig for `phabricator.url` if not set locally This setting is also per repo; see the previous commit for details. The existing `conduit_uri` setting is the previous name of `phabricator.uri`[1] and while it could easily be queried before the latter for compatibility, the config in this repo has '/api' appended. That's already done in `callconduit()`, which would clearly end up giving the wrong result. It looks like the path of the URL is now ignored in user configs[2], so add the modern setting without it to this repo's .arcconfig. Sadly, we still need to have contributors configure `auth.hg.phabtoken` (and therefore `auth.hg.prefix` to link it to `phabricator.url`) in order to submit patches, but at least now it's localized to a single section.

phabricator: use .arcconfig for the callsign if not set locally (issue6243) This makes things easier for people working with more than one repository because this file can be committed to each repository. The bug report asks to read <repo>/.arcrc, but AFAICT, that file lives in ~/ and holds the credentials. And we already track an .arcconfig file. Any callsign set globally is still used if that is all that is present, but .arcconfig will override it if available. The idea behind letting the local hgrc override .arcconfig is that the developer may need to do testing against another server, and not dirty the working directory. Originally I was going to just try to read the callsign in `getrepophid()` if it wasn't present in the hg config. That works fine, but I think it also makes sense to read the URL from this file too. That would have worked less well because `readurltoken()` doesn't have access to the repo object to know where to find the file. Supplimenting the config mechanism is less magical because it reports the source and value of the properties used, and it doesn't need to read the file twice. Invalid hgrc files generally cause the program to abort. I only flagged it as a warning here because it's not our config file, not crucial to the whole program operating, and really shouldn't be corrupt in the typical case where it is checked into the repo.

config: add a function to insert non-file based, but overridable settings This will be used in the next patch. Until relatively recently (473510bf0575), there was no official way for extensions to inject per-repo config data, so it probably makes sense that `ui.setconfig()` items are sticky, and not affected by loading more config files. But that makes it cumbersome if the extension wants to allow the data it might add to be overridden by any data in the local hgrc file. The only thing I could get to work was to load the local hgrc first, and then check if the source for the config item that should be overridden was *not* the local hgrc file name. But that's brittle because in addition to the file name, the source contains the line number, there are the usual '\' vs '/' platform differences, etc. Differential Revision: https://phab.mercurial-scm.org/D7933
