bundle2: make server.bundle2.stream default to True Support for bundle2 streaming clones has been shipped in Mercurial 4.5 (7eedbd5d4880), but was never activated by default. It's time to have more people use it. The new format allows streaming clones to transport cache (hooray for speed) and phaseroots (fixes phase-related issues). Changes in tests: bundle2 capabilities now have "stream=v2" (plus a '\n' as a separator) and therefore take 14 bytes more: "%0Astream%3Dv2". Tip for tests that have data encoded with CBOR: 0xd3 - 0xc5 = 14. $USUAL_BUNDLE2_CAPS$ replaces $USUAL_BUNDLE2_CAPS_SERVER$, which is the same thing, but without "stream=v2". Since streaming clones now also transfer caches, the reported byte and file counts are higher (e.g. 816 bytes in 9 files instead of 613 bytes in 4 files, a bit of --debug and manual math confirms that the caches take these extra 203 bytes in 5 files).

tests: split capabilities into separate lines while searching for "narrow" This test is interested only in capabilities that are related to narrow, so let's omit everything else. Makes it easier to update other capabilities (and "rev-branch-cache" is one of the usual patterns that are already present in tests/common-patterns.py anyway).

py3: resolve Unicode issues around `hg serve` on Windows 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.

run-tests: avoid os.getcwdb() on Windows 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.

run-tests: quote PYTHON when spawning a subprocess Same reason as 5abc47d4ca6b. This covers running *.py tests, as well as inline python blocks. I didn't hit the path around line 3079, but it seems correct to quote.

narrow: add test showing that local-to-local narrow clones don't work It turns out they've never actually worked: prior to some recent refactoring they just unintentionally followed the full-clone path, which we unintentionally relied on in a test at Google.

fastannotate: process files as they arrive 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

py3: make osenvironb a proxy for, instead of a copy of os.environ where needed 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.

memctx: simplify _manifest with new revlog nodeids 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.

context: remove unused overlayfilectx (API) It seems that this was maybe used in an extension but at this point nothing in lfs, hg-experimental, or any other cursory repo looked at has a reference to this class; so, for now, let's just remove it.

context: fix typo in workingcommitctx This was probably a copy pasta error in 745e3b485632. Refactoring memctx code exposed this bug.

filectx: fix return of renamed 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.

tests: glob over some quoting differences in test-narrow-widen-no-ellipsis.t

py3: byteify contrib/check-config.py The corresponding *.t still fails because of bytes (with a 'b' prefix) vs str printing, but no longer crashes. # skip-blame for b'' prefixing

tests: quote PYTHON usage Python3 defaults to installing under "Program Files".

py3: add a missing b'' for Windows I tried ./contrib/byteify-strings.py, but there were way too many changes (and most looked wrong). This was hit with test-check-interfaces.py. # skip-blame for b'' prefixes

log: make changesetformatter pass in changectx to formatter It wasn't necessary before, but user templates may have keywords that aren't filled in by the changesetformatter.

journal: use changesetformatter to properly nest list of commits in JSON Before, two separate JSON documents were interleaved. I chose the field name "changesets" over the option name "commits", since each entry is called a "changeset" in log templates.

journal: do not pass in repolookuperror string to template (BC) This doesn't look like data, but a warning message.

journal: inline formatted nodes and date into expression The variable name "str" was misleading since these values aren't always strings.

journal: unify template name for "nodes" (BC) This is a part of the name unification. https://www.mercurial-scm.org/wiki/GenericTemplatingPlan#Dictionary .. bc:: ``{oldhashes}`` and ``{newhashes}`` in journal template are renamed to ``{oldnodes}`` and ``{newnodes}`` respectively.

localrepo: extract resolving of opener options to standalone functions 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

localrepo: use boolean in opener options Not sure why we're using an integer for a flag value here. I'm pretty sure nothing relies on values being 1. While we're here, convert to a dict comprehension. Differential Revision: https://phab.mercurial-scm.org/D4575

localrepo: move store() from store module I want logic related to requirements handling to be in the localrepo module so it is all in one place. I would have loved to inline this logic. Unfortunately, statichttprepo also calls it. I didn't want to inline it twice. We could potentially refactor statichttppeer. But meh. Differential Revision: https://phab.mercurial-scm.org/D4574

localrepo: resolve store and cachevfs in makelocalrepository() 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

localrepo: document and test bug around opening shared repos 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

localrepo: move requirements reasonability testing to own function 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(). But I think having a line between basic membership testing and compatibility checking is more powerful as it will help differentiate between missing support and buggy behavior. Differential Revision: https://phab.mercurial-scm.org/D4571

statichttprepo: use new functions for requirements validation 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. Differential Revision: https://phab.mercurial-scm.org/D4570

localrepo: validate supported requirements in makelocalrepository() This should be a glorified code move. I did take the opportunity to refactor things. We now have a separate function for gathering requirements and one for validating them. I also mode cosmetic changes to the code, such as not using abbreviations and using a set instead of list to model missing requirements. Differential Revision: https://phab.mercurial-scm.org/D4569

localrepo: read requirements file in makelocalrepository() 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

localrepo: check for .hg/ directory in makelocalrepository() As part of this, we move the check to before .hg/hgrc is loaded, as it makes sense to check for the directory before attempting to open a file in it. Differential Revision: https://phab.mercurial-scm.org/D4567

localrepo: load extensions in makelocalrepository() 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

localrepo: copy ui in makelocalrepository() We will want to load the .hg/hgrc file from makelocalrepository() so we can consult its options as part of deriving the repository type. This means we need to create our ui instance copy in that function. Differential Revision: https://phab.mercurial-scm.org/D4565

localrepo: move some vfs initialization out of __init__ 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. Differential Revision: https://phab.mercurial-scm.org/D4564

localrepo: create new function for instantiating a local repo object 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

transaction: make entries a private attribute (API) 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.

narrow: don't send the changelog information when widening without ellipses When we widen anon-ellipses narrow copy, the server sends the changelog information of all the changesets. The code was copied from ellipses case and in ellipses cases, it's required to send the new changelog data. But in non-ellipses cases, we don't need to send the changelog data as we will have all the changesets locally. Before this patch, there was a overhead of ~8-10 mins on each widening call because of all the changelog information being pulled and being applied. After this patch, we no more pull the changelog information. So this patch can save ~5 mins on Mozilla repo on each widening and more on repos which have more changesets. When we apply an empty changelog from changegroup, there is a devel-warn. This patch kind of hacks to silence that devel-warn. Differential Revision: https://phab.mercurial-scm.org/D4639

changegroup: add functionality to skip adding changelog data to changegroup In narrow extension, when we have a non-ellipses narrow working copy and we extend it, we pull all the changelog data again and the client tries to reapply all that changelog data. While downloading millions of changeset data is still not very expensive but applying them on the client side is very expensive and takes ~10 minutes. These 10 minutes are added to every `hg tracked --addinclude <>` call and extending a narrow copy becomes very slow. This patch adds a new changelog argument to cgpacker.generate() fn. If the changelog argument is set to False, we won't yield the changelog data. We still have to iterate over the deltas returned by _generatechangelog() because that's a generator and builds the data for clstate variable which is required for calculating manifests and filelogs.

'before' is 9db85644, and does not include that example commit's improvements. diff --git: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 1.327 s +- 0.051 s | 1.296 s +- 0.009 s | 97.7% m-u | | x | 1.310 s +- 0.020 s | 1.295 s +- 0.015 s | 98.9% m-u | x | | 1.295 s +- 0.018 s | 1.296 s +- 0.007 s | 100.1% m-u | x | x | 83.5 ms +- 0.8 ms | 84.1 ms +- 0.8 ms | 100.7% l-d-r | | | 205.1 ms +- 3.5 ms | 205.0 ms +- 3.8 ms | 100.0% l-d-r | | x | 194.2 ms +- 5.6 ms | 192.3 ms +- 4.3 ms | 99.0% l-d-r | x | | 99.1 ms +- 2.2 ms | 97.8 ms +- 0.9 ms | 98.7% l-d-r | x | x | 66.2 ms +- 1.0 ms | 67.2 ms +- 2.7 ms | 101.5% diff -c . --git: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 233.9 ms +- 1.9 ms | 235.6 ms +- 5.1 ms | 100.7% m-u | | x | 151.4 ms +- 1.2 ms | 152.2 ms +- 2.0 ms | 100.5% m-u | x | | 234.8 ms +- 2.7 ms | 235.0 ms +- 2.7 ms | 100.1% m-u | x | x | 127.8 ms +- 2.1 ms | 126.0 ms +- 1.1 ms | 98.6% l-d-r | | | 82.5 ms +- 1.6 ms | 82.3 ms +- 2.0 ms | 99.8% l-d-r | | x | 3.742 s +- 0.017 s | 3.819 s +- 0.208 s | 102.1% l-d-r | x | | 84.4 ms +- 1.5 ms | 83.2 ms +- 1.0 ms | 98.6% l-d-r | x | x | 751.2 ms +- 5.0 ms | 755.8 ms +- 12.9 ms | 100.6% rebase -r . --keep -d .^^: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 5.519 s +- 0.038 s | 5.526 s +- 0.057 s | 100.1% m-u | | x | 5.588 s +- 0.048 s | 5.607 s +- 0.061 s | 100.3% m-u | x | | 5.520 s +- 0.044 s | 5.546 s +- 0.059 s | 100.5% m-u | x | x | 586.6 ms +- 12.8 ms | 554.9 ms +- 21.2 ms | 94.6% <-- l-d-r | | | 629.8 ms +- 5.5 ms | 627.4 ms +- 6.6 ms | 99.6% l-d-r | | x | 6.165 s +- 0.058 s | 6.255 s +- 0.303 s | 101.5% l-d-r | x | | 270.2 ms +- 2.3 ms | 271.4 ms +- 2.7 ms | 100.4% l-d-r | x | x | 4.700 s +- 0.025 s | 1.651 s +- 0.016 s | 35.1% <-- status --change . --copies: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 215.4 ms +- 2.3 ms | 216.5 ms +- 4.2 ms | 100.5% m-u | | x | 132.9 ms +- 1.2 ms | 132.0 ms +- 1.4 ms | 99.3% m-u | x | | 217.0 ms +- 1.9 ms | 215.4 ms +- 1.9 ms | 99.3% m-u | x | x | 108.6 ms +- 1.0 ms | 108.2 ms +- 1.5 ms | 99.6% l-d-r | | | 80.0 ms +- 1.3 ms | 80.5 ms +- 1.1 ms | 100.6% l-d-r | | x | 3.916 s +- 0.187 s | 3.966 s +- 0.236 s | 101.3% l-d-r | x | | 84.4 ms +- 3.1 ms | 83.9 ms +- 1.1 ms | 99.4% l-d-r | x | x | 758.0 ms +- 8.2 ms | 753.5 ms +- 5.0 ms | 99.4% status --copies: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 1.905 s +- 0.025 s | 1.910 s +- 0.044 s | 100.3% m-u | | x | 1.892 s +- 0.009 s | 1.895 s +- 0.012 s | 100.2% m-u | x | | 1.891 s +- 0.012 s | 1.902 s +- 0.018 s | 100.6% m-u | x | x | 93.3 ms +- 0.9 ms | 93.4 ms +- 0.8 ms | 100.1% l-d-r | | | 570.7 ms +- 7.8 ms | 571.9 ms +- 18.5 ms | 100.2% l-d-r | | x | 561.5 ms +- 5.2 ms | 562.9 ms +- 6.1 ms | 100.2% l-d-r | x | | 171.7 ms +- 2.6 ms | 171.9 ms +- 1.2 ms | 100.1% l-d-r | x | x | 142.7 ms +- 2.0 ms | 140.3 ms +- 1.0 ms | 98.3% update $rev^; ~/src/hg/hg{hg}/hg update $rev: repo | N | T | before (mean +- stdev) | after (mean +- stdev) | % of before ------+---+---+------------------------+-----------------------+------------ m-u | | | 3.126 s +- 0.016 s | 3.128 s +- 0.015 s | 100.1% m-u | | x | 3.014 s +- 0.068 s | 3.008 s +- 0.031 s | 99.8% m-u | x | | 3.143 s +- 0.037 s | 3.184 s +- 0.086 s | 101.3% m-u | x | x | 308.0 ms +- 1.8 ms | 308.1 ms +- 5.7 ms | 100.0% l-d-r | | | 430.8 ms +- 4.5 ms | 436.4 ms +- 8.7 ms | 101.3% l-d-r | | x | 9.676 s +- 0.127 s | 9.945 s +- 0.272 s | 102.8% l-d-r | x | | 254.2 ms +- 3.3 ms | 255.7 ms +- 3.1 ms | 100.6% l-d-r | x | x | 1.571 s +- 0.030 s | 1.555 s +- 0.014 s | 99.0% Differential Revision: https://phab.mercurial-scm.org/D4606

narrow: use diffmatcher to send only new filelogs in non-ellipses widening Before this patch, when we widen a non-ellipses narrow clone, we downloads all the filelogs matching the resulting new matcher. This is same as the ellipses case but can be improved because, we don't pull new csets in non-ellipses cases, we can only download the new added files instead of downloading all the files which matches the new matcher. So, we only download files which matches the new matcher but does not matches the old matcher. There exists a match.differencematcher() which is used here. This will lead to significant amount of speedup in extending a non-ellipses narrow copy on large repos because we will download and process only the new required filelogs. The tests changes demonstrate that we are downloading now less files. Thanks to Augie for pointing that functionality of differencematcher exists in core.
