Presumably we're going to want to use CreateProcessW(), and possibly get rid of pycompat.getcwd() here (which maps to the DeprecationWarning causing os.getcwdb()) to use os.getcwd() directly. But this was a minimal change to get rid of some stacktraces in test-run-tests.t.

Any call to this issues a DeprecationWarning about the Windows bytes API being deprecated. There are a handful of these calls in core, but test-run-tests.t was littered with these, as it's printed everytime run-tests.py is launched. I'm not sure what the long term strategy for Unicode on Windows in the test runner is, but this seems no worse than the current conversion strategy.

peer.commandexecutor()'s context manager waits for all responses to arrive in its __exit__() method. We want to process the results as they arrive, so we should do that inside the context manager scope. Note that the futures' result() methods have been replaced to make sure that the command executor's sendcommands() method is called when the first future's result is requested, so we don't need to do that. A minor side-effect is that we can no longer easily tell when the server has started sending us responses, so that long statement was lost. Differential Revision: https://phab.mercurial-scm.org/D4666

Without this, TESTDIR and a few other variables weren't defined in the *.t test. I didn't bother implementing all of the view functions for simplicity. All that is actually used is __{get,set}item__(), get() and pop(), but the rest seems easy enough to add for futureproofing.

This was originally written before we had modifiednodeid and addednodeid, so we had to get the parents of the context, the data from the function, and then hash that. This is much more simple now and helps refactor more code later.

How is this not blowing up everywhere? It seems that filelog.renamed has always returned False (incorrectly a boolean) instead of the assumed None. Tracing through history, you need to skip over my move of code in 2013 by annotating from 896193a9cab4^ and you can see the original code is from 2007 (180a3eee4b75) and that ab9fa7a85dd9 broke this by assuming renamed was a bool (instead of None). Refactoring memctx code later exposed this bug.

Requirements and config options are converted into a dict which is available to the store vfs to consult. This is how storage options are communicated from the repo layer to the storage layer. Currently, we do that option resolution in a private method on the repo instance. And there is a single method doing that resolution. Opener options are logically specific to the storage backend they apply to. And, opener options may wish to influence how the repo object/type is constructed. So it makes sense to have more granular storage option resolution that occurs before the repo object is instantiated. This commit extracts the code for resolving opener options into new module-level functions. These functions are run before the repo instance is constructed. As part of the code move, we split the option resolution into generic and revlog-specific options. After this commit, we no longer add revlog-specific options to repos that don't have a revlog requirement. Some of these opener options and associated config options might make sense on alternate storage backends. We can always reuse config options and opener option names for other backends. But we shouldn't be passing opener options to storage backends that won't recognize them. I haven't done it here, but after this commit it should be possible for store backends to validate the set of opener options it receives. Because localrepository.openerreqs is no longer used after this commit, it has been removed. I'm not super thrilled about the code outside of localrepo that is adding requirements and updating opener options. We'll probably want to create a more formal API for that use case that constructs a new repo instance and poisons the old repo object. But this was a pre-existing issue and can be dealt with later. I have little doubt it will cause me troubles as I continue to refactor how repository objects are instantiated. .. api:: ``localrepository.openerreqs`` has been removed. Override ``localrepo.resolvestorevfsoptions()`` to add custom opener options. .. api:: ``localrepository._applyopenerreqs()`` has been removed. Use ``localrepo.resolvestorevfsoptions()`` to add custom opener options. Differential Revision: https://phab.mercurial-scm.org/D4576

This is mostly a code move and refactor. One change is that we now explicitly look for requirements indicating a share is being used rather than blindly try to read from .hg/sharedpath. Requirements *should* be all that is necessary to dictate high-level behavior and I'm not sure why the previous code was doing what it was. The previous code has been in place since 87d1fd40f57e (authored in 2009). And the commit immediately after that (971e38a9344b) introduced ``hg.share()`` and always wrote the ``shared`` requirement. And as far as I can tell, every revision of ``hg.share()`` since has written either the ``shared`` or ``relshared`` requirement. So I'm pretty sure we don't need to maintain BC by always looking for and honoring the ``.hg/sharedpath`` file even if a requirement isn't present. .. bc:: A repository will no longer use shared storage if it has a ``.hg/sharedpath`` file but no entry in ``.hg/requires`` saying it is shared. This change should not have any end-user impact, as all shared repos should have a ``.hg/requires`` file indicating this. Differential Revision: https://phab.mercurial-scm.org/D4573

As part of refactoring this code, I realized that we don't validate the requirements of a shared repository. This commit documents that next to the requirements validation code and adds a test demonstrating the buggy behavior. I'm not sure if I'll fix this. But it is definitely a bug that users could encounter, as LFS, narrow, and potentially other extensions dynamically add requirements on first use. One part of this I'm not sure about is how to handle loading the .hg/hgrc of the shared repo. We need to do that in order to load extensions. But we don't want that repo's hgrc to overwrite the current repo's. Differential Revision: https://phab.mercurial-scm.org/D4572

Just because we know how to handle each listed requirement doesn't mean that set of requirements is reasonable. This commit introduces an extension-wrappable function to validate that a set of requirements makes sense. We could combine this with ensurerequirementsrecognized().

The new code in localrepo for requirements gathering and validation is more robust than scmutil.readrequires(). Let's port statichttprepo to it. Since scmutil.readrequires() is no longer used, it has been removed. It is possible extensions were monkeypatching this to supplement the set of supported requirements. But the proper way to do that is to register a featuresetupfuncs. I'm comfortable forcing the API break because featuresetupfuncs is more robust and has been supported for a while. .. api:: ``scmutil.readrequires()`` has been removed. Use ``localrepo.featuresetupfuncs`` to register new repository requirements. Use ``localrepo.ensurerequirementsrecognized()`` to validate them.

Previously, scmutil.readrequires() loaded the requirements file and validated its content against what was supported. Requirements translate to repository features and are critical to our plans to dynamically create local repository types. So, we must load them in makelocalrepository() before a repository instance is constructed. This commit moves the reading of the .hg/requires file to makelocalrepository(). Because scmutil.readrequires() was performing I/O and validation, we inlined the validation into localrepository.__init__ and removed scmutil.readrequires(). I plan to remove scmutil.readrequires() in a future commit (we can't do it now because statichttprepo uses it). Differential Revision: https://phab.mercurial-scm.org/D4568

Behavior does change subtly. First, we now load the hgrc before optionally setting up the vfs ward. That's fine: the vfs ward is for debugging and we know we won't hit it when reading .hg/hgrc. If the loaded extension were performing repo/vfs I/O, then we'd be worried. But extensions don't have access to the repo object that loaded them when they are loaded. Unless they are doing stack walking as part of module loading (which would be crazy), they shouldn't have access to the repo that incurred their load. Second, we now load extensions outside of the try..except IOError block. Previously, if loading an extension raised IOError, it would be silently ignored. I'm pretty sure the IOError is there for missing .hgrc files and should never have been ignored for issues loading extensions. I don't think this matters in reality because extension loading traps I/O errors. Differential Revision: https://phab.mercurial-scm.org/D4566

In order to make repository types more dynamic, we'll need to move the logic for determining repository behavior out of localrepository.__init__ so we can influence behavior before the type is instantiated. This commit starts that process by moving working directory and .hg/ vfs initialization to our new standalone function for instantiating local repositories. Aside from API changes, behavior should be fully backwards compatible. .. api:: localrepository.__init__ now does less work and accepts new args Use ``hg.repository()``, ``localrepo.instance()``, or ``localrepo.makelocalrepository()`` to obtain a new local repository instance instead of calling the ``localrepository`` constructor directly.

Today, there is a single local repository class - localrepository. Its __init__ is responsible for loading the .hg/requires file and taking different actions depending on what is present. In addition, extensions may define a "reposetup" function that monkeypatches constructed repository instances, often by implementing a derived type and changing the __class__ of the repo instance. Work around alternate storage backends and partial clone has made it clear to me that shoehorning all this logic into __init__ and operating on an existing instance is too convoluted. For example, localrepository assumes revlog storage and swapping in non-revlog storage requires overriding e.g. file() to return something that isn't a revlog. I've authored various patches that either: a) teach various methods (like file()) about different states and taking the appropriate code path at run-time b) create methods/attributes/callables used for instantiating things and populating these in __init__ "a" incurs run-time performance penalties and makes code more complicated since various functions have a bunch of "if storage is X" branches. "b" makes localrepository quickly explode in complexity. My plan for tackling this problem is to make the local repository type more dynamic. Instead of a static localrepository class/type that supports all of the local repository configurations (revlogs vs other, revlogs with ellipsis, revlog v1 versus revlog v2, etc), we'll dynamically construct a type providing the implementations that are needed for the repository on disk, derived from the .hg/requires file and configuration options. The constructed repository type will be specialized and methods won't need to be taught about different implementations nor overloaded. We may also leverage this functionality for building types that don't implement all attributes. For example, the "intents" feature allows commands to declare that they are read only. By dynamically constructing a repository type, we could return a repository instance with no attributes related to mutating the repository. This could include things like a "changelog" property implementation that doesn't check whether it needs to invalidate the hidden revisions set on every access. This commit establishes a function for building a local repository instance. Future commits will start moving functionality from localrepository.__init__ to this function. Then we'll start dynamically changing the returned type depending on options that are present. This change may seem radical. But it should be fully compatible with the reposetup() model - at least for now. Differential Revision: https://phab.mercurial-scm.org/D4563

This attribute is tracking changes to append-only files. It is an implementation detail and should not be exposed as part of the public interface. But code in repair was accessing it, so it seemingly does belong as part of the public API. But that code in repair is making assumptions about how storage works and is grossly wrong when alternate storage backends are in play. We'll need some kind of "strip" API at the storage layer that knows how to handle things in a storage-agnostic manner. I don't think accessing a private attribute on the transaction is any worse than what this code is already doing. So I'm fine with violating the abstraction for transactions. And with this change, all per-instance attributes on transaction have been made private except for "changes" and "hookargs." Both are used by multiple consumers and look like they need to be part of the public interface. .. api:: Various attributes of ``transaction.transaction`` are now ``_`` prefixed to indicate they shouldn't be used by external consumers.
