It isn't operative until somebody adds a `-S` or support for breaking paths on a subrepo boundary to the command anyway.\n\nThe real trap here is catching all of the subrepo references in the parent.  Say you have a repo that maps like this:\n\n    2 -> S1\n    1 -> S1\n\nIf you `hg fix -r 2` and it edits S1, that will cause parent rev 1 to be dangling.  I guess we could modify `.hgsubstate` in 1 too without running fixers there.  But what if 1 is already public?  The preflight checks will be extensive.

That makes it so that the revision in the\nparent can't be checked out, and the problem gets propagated on push.  Mercurial\nalready tries to defend against this sort of dangling reference by pushing *all*\nsubrepo revisions first.  This reuses the checks that trigger warnings in\n`hg verify` to bail on the push unless using `--force`.\n\nI thought about putting this on the server side, but at that point, all of the\ndata has been transferred, only to bail out.  Additionally, SCM Manager hosts\nsubrepos in a location that isn't nested in the parent, so normal subrepo code\nwould complain that the subrepo is missing when run on the server.\n\nBecause the push command pushes subrepos before calling this exchange code, a\nsubrepo will be pushed before the parent is verified.

For the most part I've been tackling this as a side project when I'm waiting on compiles.\n\nAs to doing individual files: that's well and good, and might be a viable approach for mypy. That said, my sense has been that mypy is faster and significantly less useful, since we don't get cross-file analysis of what's going on. I _think_ pytype gets faster as we add more annotations, so my rough thought thus far as been to try and get some subset of the codebase clean, transitively, and then try to start stamping some types on important functions and interfaces to constrain things. Where I'd _really_ like to get is to be able to migrate the `@command` decorators and friends to use strings instead of bytes, and be able to recommend typechecking as a way for extension authors to clean things up, but that'll take a while.","author":"durin42","id":"110437","dateCreated":"1574531296","dateModified":"1574531296"},{"type":"comment","comment":">>!

There are two traps for anybody dealing with this on Windows to be aware of:\n\n1. Running `.\/hg debuginstall` will still run py2, even if it was built with py3.

(I realize I could just edit $PATH, but it seems that the point of py.exe is to keep python.exe off of $PATH so that multiple installs can be managed.

Try the pytype invocation from the test at the end of the series and you'll see what I mean.\n\nOk, trying `pytype mercurial\/dagparser.py` I get a couple of those errors:\n```\nFile \"...\/mercurial\/dagparser.py\", line 172, in parsedag: Function bytestr.__init__ was called with the wrong arguments [wrong-arg-types]\n  Expected: (self, ints: Iterable[int])\n  Actually passed: (self, ints: str)\n```\n\nMy point was that we need to keep \"mercurial\/pycompat.py\" passing pytype before considering modules it depends on. Once the missing `type: ` is added and bytestr <-> _bytestr trick applied, it's okay but the error in dagparser.py persists...\nLooking closer at the error above, it mentions `bytestr.__init__`, not `__new__` (and there is in fact no type annotation for `__new__` in [typeshed](https:\/\/github.com\/python\/typeshed\/blob\/34d68ab0a2117a08fa221d3a10884f35cacf2cdc\/stdlib\/2and3\/builtins.pyi#L559)). So I suspect the \"Callable\" trick is not enough and we'd need a workaround similar to da925257 by @yuja .

If templates are embedded in the binary, how do users define their own custom versions of the build-in templates? We already have a permissions problem when the provided templates are read-only and the user can't edit them in place.

I was reminded that we have `hg cp --force` to \"forcibly copy over an existing managed file\". If you don't use that and try to copy onto an existing file, you'll get this hint: \"'hg copy --force' to replace the file by recording a copy\". It sounds like the plan was to allow you to copy a file onto an existing one to record it as a copy. We also have tests in `test-copy.t` showing the status of that.

Often the root cause is no\navailability of spot instances in the given availability zone.\n\nThis commit teaches our CI system to recognize when a spot instance\nrequest has failed and to retry it.\n\nTo do this, we create a pair of new Lambda functions, \"spot instance\nrequest monitor\" and \"start job.\" The former is invoked periodically\nvia CloudWatch Event. It scans all jobs waiting on a spot instance\nrequest. If the spot instance request is cancelled, it calls into\nthe \"start job\" function, which simply calls an internal API for\ntrying to start a job given a job ID.\n\nOur strategy for retrying spot instance requests is to try to use\nthe \"next\" availability zone for the given region. We will cycle\nthrough availability zones until a spot instance request is\nacted on. In my testing, this always works. Although it could\ntake several minutes to cycle through all availability zones and\nfor an availability zone to have instance availability.\n\nThere are definitely other strategies we could try. For example,\nwe could try another AWS region. Or we could launch an on-demand\ninstance after N failures. Or we could launch a difference EC2\ninstance type - one with hopefully more availability. Or we could\nuse spot fleet requests (which allow launching from multiple\ninstance types). The easiest is probably to launch an on-demand\ninstance. But until we need this functionality, I'm inclined to\nnot build it, as I like the consistency of always using spot\ninstances.","testPlan":"","lineCount":"341","dependsOn":["6925"],"reviewers":[],"ccs":["mercurial-devel"],"actions":[{"type":"plan-changes","author":"indygreg","id":"104748","dateCreated":"1571280699","dateModified":"1571280699"},{"type":"update","diffId":"16723","author":"indygreg","id":"101639","dateCreated":"1569904860","dateModified":"1569904860"},{"type":"update","diffId":"16720","author":"indygreg","id":"101616","dateCreated":"1569902250","dateModified":"1569902250"}],"dateCreated":"1569902250","dateModified":"1571280700","status":"Changes Planned"},{"id":"6924","callsign":"HG","title":"ci: store job start parameters in DynamoDB","author":"indygreg","summary":"This makes it vastly easier to retry or retrigger a job,\nsince the instance launch state will be stored in the\ndatabase instead of in an ad-hoc SQS message.","testPlan":"","lineCount":"52","dependsOn":["6922"],"reviewers":[],"ccs":["mercurial-devel"],"actions":[{"type":"plan-changes","author":"indygreg","id":"104746","dateCreated":"1571280675","dateModified":"1571280675"},{"type":"update","diffId":"16718","author":"indygreg","id":"101600","dateCreated":"1569902245","dateModified":"1569902245"}],"dateCreated":"1569902245","dateModified":"1571280675","status":"Changes Planned"},{"id":"6922","callsign":null,"title":"ci: implement a \"try server\"","author":"indygreg","summary":"This commit implements a new CI component which allows privileged users\nto upload Mercurial bundles and have automation run against them.

It can be seen at\nhttps:\/\/ci.hg.gregoryszorc.com\/\n\nMercurial's existing CI infrastructure is under-loved. This commit\nimplements an in-repository CI system for Mercurial.\n\nMy main motiviation for doing this is that the transition to Python 3\nwill require a substantial investment in CI and I think this is a good\nopportunity to revisit how the project currently does CI. The existing\nCI system is rooted in CI technology from yesterday and I think we can\niterate faster going forward by implementing CI in the main repository\non top of infrastructure that anyone can stand up if they have a credit\ncard.\n\nEverything in the new CI system is built on top of AWS. There are no\npersistent EC2 instances: all compute is ephemeral in \"serverless\"\nLambda functions or performed on EC2 instances spun up to run\nindividual jobs.\n\nI rejected building on top of existing CI platforms like Azure Pipelines\nor GitHub Actions because a) support for Mercurial is poor b) they don't\nprovide enough CPU horsepower to run Mercurial's test harness quickly c)\nif you want to buy enough CPU horsepower to do so, you need to run\npersistent servers which end up sitting around idle most of the time,\naccruing large bills. Standing up a basic CI system built on top of\nsimple event triggers (such as database row insertions triggering the\nlaunch of an EC2 instance to run a job) is not a lot of lines of code,\nsurprisingly. And the benefits we get from containing the entire stack\nand having everything be open source can be substantial.\n\nThe code in this commit is currently running at\nhttps:\/\/ci.hg.gregoryszorc.com\/ and is running out of an AWS account\nI currently have chained up to my personal AWS account. That includes\nbilling: I'm currently running this out of my own pocket. I'm fine\nwith that for now. But we'll probably want to move account ownership\nand billing to the official Mercurial Project at some point. Although\nif you catch me in a generous mood, I may foot the bill semi-permanently.\nAlthough it would be great to get the 501(c)(3) tax status hooked up\nso I can write off the expense. That may mean transferring account\nownership to the Mercurial Project. We can discuss offline...\n\nA lot of functionality is very rough around the edges. And there's a\nlot that could be implemented. The web interface in particular is\nrather primitive (I'm not great at web development). But it gets the\njob done. I've already found the functionality very useful for tracking\ndown Python 3 issues.\n\nThis is a lot of code to review at once. I suggest starting by reading\nthe added README.rst. Most of the business logic lives in the Lambda\nfunctions in ci.py.

I don't think that's possible here, since the obsolete\nrevisions are explicitly excluded.  But maybe there are other reasons someone\nwouldn't want older revisions obsoleted.  The config name reflects the fact that\nI'm not sure if other things like import should get this too.\n\nI suspect that we could wrap a function deeper in the pull sequence to improve\nboth the code and the UX.  For example, when pulling an obsolete marker, it can\nprint out a warning that the working directory parent is obsolete, but that\ndoesn't happen here.  (It won't happen with this test.  It *should* without the\n`--bypass` option, but doesn't.)  It should also be possible to not have to\nquery the range of new revisions, and maybe it can be added to the existing\ntransaction.\n\n[1] https:\/\/bitbucket.org\/facebook\/hg-experimental\/src\/default\/hgext3rd\/pullcreatemarkers.py","testPlan":"","lineCount":"69","dependsOn":[],"reviewers":[],"ccs":["pulkit","sheehan","Kwan","mercurial-devel","marmoute"],"actions":[{"type":"inline","comment":"Right, and this is probably the typical case.

As it\nstands now, this installation won't see that, but does see\n$HOME\/.local\/lib\/python2.7\/site-packages, and the bundled `pip` will install\nthere with `--user`.  It does seem like only seeing the second `--user` location\nwill get confusing, especially since the current behavior is that\n`pip install --user ...` just works for `pip` in PATH.\n\nThe prerequisite is to have python3 to run the script, and a working python2\nwith docutils installed to feed to the script.  (The latter is used to build and\ninstall the documentation for Mercurial without polluting the python distro to\nbe packaged, so maybe we can use python3 there.)\n\nThe general flow is to download, build and install OpenSSL off to the side, and\nthen use that to download, build and install Python to a separate staging area.\nThe certifi package is bundled for the root certificates.  I'm not an expert in\nwhat OpenSSL compilation options should be used, so if there's a way to tighten\nthings up, let me know.\n\nI don't like how the other packaging scripts assume an existing path on the\nsystem, so this uses the build directory to stage the Python and OpenSSL builds.\nThe existing system python installer stages in `build\/mercurial`, but this\nbuilds Mercurial into the staged python directory.  (That path includes version\ninfo, so it shouldn't be much to add python3 support and build both at the same\ntime.)  I also wasn't sure where to stash the downloads (they seem somewhat\nuseful to cache), so I stuffed them into the packages directory (which gets\nclobbered by `make clean`).\n\nTo distinguish from the system python installer (and with an eye towards\npython3), `-py2.7` is added after the Mercurial version to the file name.\nAltogether, this takes about 10 minutes to build on a 2018 Mac Mini.\n\nThere's additional followup work to do, in addition to the obvious py3 support-\nthe readme still mentions depending on system python, and this could probably be\ndriven by the makefile as a separate target.  It should be trivial to sign the\nbinaries and installer, and slightly less trivial to notarize the *.pkg, but\ndefinitely doable.  The files in the final *.pkg can be listed like so:\n\n    pkgutil --payload-files dist\/Mercurial-*.pkg\n\nLooking at that, there's probably a bunch of junk that can be removed:\n\n    - include\/\n    - distutils\/tests\/\n    - lib-tk\/test\/\n    - ctypes\/test\/,\n    - unittest\n    - test\n    - lib2to3\n    - idle\n    - pydoc\n\nI didn't see config options for that, and maybe it isn't worth it.

The primary usage scenario here is scripts (as explained in issue6014) -- regular users lived without this feature for years and didn't care (enough to file a bug) about getting all config options, or their default values, \/\/or\/\/ the experimental status (they could and still can read it in hg help config). `--registered` is needed for things like shell completions, and the output needs to be clear and parseable (and consistent with what regular showconfig shows).\n\nEven adding \"(default: x)\" to values already complicates the parsing process to get multiple config options in a script. Yeah, a script can get individual values one by one, but it can take ages because of the start-up time (again, this is important for interactive scripts like shell completions).\n\nLet's add a test to this patch that demonstrates that scripts can \/\/easily\/\/ use this new functionality. Something like `$ hg showconfig --registered -T '{name}={value}\\n' | egrep '^(color|diff)'`. Notice how this uses -T, which is recommended, but people writing scripts in the wild may not even use, and extra things in the output (i.e. anything other than just key and value) will trip their scripts up. Maaaybe if we put a strongly worded note in hg help showconfig about scripting and usage of -T, maybe then adding \"(EXPERIMENTAL)\" would make sense. But I think the current format of adding it to the key is weird and it would be better to add it to the end of the line, similar to what experimental CLI flags have in the output of `hg help -v command` (if at all, because, again, that is not how regular showconfig behaves and we do have both defaults and experimental statuses in hg help config).\n\nSorry for coming up with this new condition only now, but I thought everyone was already on the same page.","author":"av6","id":"99199","dateCreated":"1566624258","dateModified":"1566624258"},{"type":"reject","author":"av6","id":"99198","dateCreated":"1566624258","dateModified":"1566624258"},{"type":"comment","comment":">>!

I've thought of `hg push -B` as forcing the move of the bookmark, and `hg push -r` as not forcing a bookmark move, as that's how they behave (well, mostly).\nI don't know if this is a bug: the intended behavior of `push -B` is not explicitly documented, but it at least appears to be consistent with `hg pull -B`.\nBut if it wasn't for compatibility, the behavior you're trying to implement looks superior: it gives the ability to ensure that a push either moves a bookmark forward or fails, which is clearly useful. We have an extension that makes `hg push -r BOOKMARK` have such a behavior, but the fewer extensions the better.\n\nBut given compatibility constraints, this behavior probably needs to be gated by a config option.\n\nAbout more technical aspects, I have a couple of remarks:\n- the change of behavior would be clearer in the diff if you added the test in a first change, and updated the code in a second change\n- the check should probably live in some combination of `exchange.{_processcompared,_pushb2checkbookmarks}` instead (that's where the \"move forward\" logic for push is right now)\n- using `hg push -f` to overwrite the remote bookmark is not great, because -f forces several completely unrelated things (new heads, removes race checks about bookmarks, something about obsolescence markers and something about phases). No one wants to bypass all these at once. Dedicated force flags seems better, perhaps `hg push --force-bookmark BOOKMARK`, to replicate the current behavior of `hg push -B BOOKMARK`.","author":"valentin.gatienbaron","id":"99521","dateCreated":"1567374841","dateModified":"1567374841"},{"type":"comment","comment":"This is a potential fix for https:\/\/bz.mercurial-scm.org\/show_bug.cgi?id=6193\nThe actual validation is in `bundle2.handlebookmark`.\nThe rest of the changes are there to pass the `force` parameter.\nI've also made `force` available to hooks.

I started this with nothing more in mind than making the installer support more than 10.14.  But since it links against the system python, setting the MACOS_DEPLOYMENT_TARGET (or whatever it's called) errors out.  So I tried allowing PYTHON to be overridden in the makefile, so it could be pointed to the python.org install and go back to 10.9.  But @durin42 locked it into the system python in da1848f07c6a, and things just kinda snowballed from there.  He mentioned on IRC that a pyinstaller dependency wouldn't be great, and also maybe we don't want to be completely tied to PyOxidizer.  (I took it as don't preclude other methods, but maybe that needs to be clarified.)\n\n> Until PyOxidizer is ready, you may want to look into Beeware's Briefcase tool for packaging macOS applications.

Only works with Python 3.7+ at the moment now, though. The pre-built distributions on GitHub having a working Python install in them.

I'm not sure what it would take to support py2, but I'd rather everybody poured their effort in elsewhere at this point.  @durin42 mentioned on IRC that it's long past time to get off the system python, but the only real deadline is that it won't be in 10.16 a year from now.  Hopefully the codebase is still supporting py2 then, but maybe the py3 support is good enough that we don't need an official py2 installer?  End of py2 support doesn't seem like a big deal, unless some horrible TLS bug is found.\n\nI suppose a reasonable fix for supporting more OS versions is to spin up a 10.9 VM and build there.  I don't have one right now, but I do have a machine that is going to be setup to host various Mac VMs, and I don't have a problem building the installer on it if there's interest.","author":"mharbison72","id":"99265","dateCreated":"1566767478","dateModified":"1566767478"},{"type":"inline","comment":"We should be pinning versions and hashes when installing anything from the network.

It feels like it should work the same for any case where we move to a different commit without changing the working copy, such as uncommit, unamend, amend, fix (though we may want optimized code paths for some of them). So I took this patch and tried the most naive attempt at unifying the interactive version with the non-interactive version, namely to just drop the code for the interactive path (see patch below).

It's a lot of extra code to wrangle the data into creatediff form.

Also, to be really flexible it would require some way to refer to the p2 revision (i.e. you'd need to introduce an implicit or explicit reference to each of the p1 or p2 revisions). I think this would make the syntax for the most common use cases that I want to cover too complex. That being said, the proposed syntax leaves open the door for introducing such revset based filtering in the future if needed (although I think that a generic filter function would be more useful).\n\n@yuja  , I've sent an updated set of patches, following your recommendations. There are 2 patches now, since each includes its own tests. This means that the 3rd patch on the original patch set is no longer needed.

The two pipes in this example do not have the same meaning:\n\n```\no\n|\n|\n \\\n   o\n```\n\nEven if we had the unicode characters\/custom font needed to make this work, we would need at least 5 configurable variants of what is currently just a pipe. You would need hundreds of distinct characters to support all combinations of the 8 horizontal and diagonal edges in each character\/cell of the graph rendering. More than double that to support dashed lines. Maybe exclude some unused characters. It's hard to imagine making that easy to configure.\n\nYou can also imagine having the graphlog output optionally use only horizontal\/vertical edges so this can be done properly with box drawing characters. This is would complicate graphlog itself considerably, regardless of configuration.\n\nMeanwhile, this patch would be useful to some of our users, and it keeps the problems contained within the extension.","author":"hooper","id":"77628","dateCreated":"1540934965","dateModified":"1540934965"},{"type":"comment","comment":"hooper and I talked at the sprint, and they wrote up the following for why they feel we should keep this out of graphmod\/templatekw for now:\n\n> I don't think configurable graph log characters in core is a great idea right now, since it makes the empty promise that you can make logs look correct by using common fonts. E.g. the problem that pipe characters are used in several situations that just can't be handled well by one character.\n\nAs a specific example, there's no unicode line drawing characters that are fully-extended lines at 0 degrees (straight up) and 135 degrees (down to the right to the corner of the character box), so there will always be cases that can't really be represented \"perfectly\".\n\nI don't generally agree with this reasoning - limitations of unicode should not be a reason to require that we go through a separate extension like this.  The reasoning for the extension instead of just making the actual graph characters customizable was two-fold, if I remember correctly:\n\n1. there is currently some awkward code to handle extending one of the characters used to draw parent\/grandparent lines for a few lines and then switch to the other. (https:\/\/www.mercurial-scm.org\/repo\/hg\/file\/tip\/tests\/test-glog.t#l3041 shows this in action) - the code to implement this is not unicode safe (at least in python2)\n2. the current graphlog code does not currently have config knobs to control every character, I think. \n\n\nI think we should fix the code issue in #1 (I just sent D5112 for this), and then we can extended graphlog to have whatever character(s) we need, instead of attempting to do the replacements in an extension like we're currently doing?

However, sometimes there is a long chain on top, and in my case there was a separate commit upstream that fixed the typo I fixed when I amended `B` and it would be a little confusing to explain why someone's fix was \"lost\". \n\nI can see two distinct arguments in that description:\n  #  Someone else made a similar fix in an independent changeset, and you want to give them the priority.\n  #  There are many drafts stacked above it and you don't want to rewrite B.\n\n\nRegarding the first argument, the case is easily handled by \"rewinding\" your amend's change and restoring the diff provided by 'B'. The `hg rewind` command deal with this case well: `hg rewind --to B`. The use of `hg prune` in your example is wrong. By using prune, you signal that the full line of change in B' (B' and it predecessors B) is something that is unwanted. So you are not just dropping the change introduced in your amend, but the other associated change.\n\nRegarding the second argument, the one I interpret as it would create too many orphans.\nIt seems to be the consequence of the current Mercurial Project workflow where many unrelated drafts get stacked.\nThe point of the draft phase is to signal that a changeset is safe to be rewritten. In other words that the consequences of such rewriting are acceptable. If you get to the point where rewriting draft no longer feel safe you seem to have a workflow issue.\n\nFor the sake of the current argument, let's assume that the workflow would be fixed in a direction where B would be public. After your pull. In that case, B' would be \"phase-divergent\". Solving that phase-divergence will create a \u0394B changeset with just the fix (you amend change). Rebasing that \u0394B on top of the other fix will make it disappears, giving priority as you intended.\n\n> So I'd prefer to mark B as no longer obsolete. I know I can do that with `hg strip B'`, but that also strips `X`, which is probably not a big loss, but it's a weird side-effect.\n\nYou cannot really strip the obsmarkers between B and B' without stripping B' itself. If B' end up being visible again it's Evolve that would be lost introducing confusion too.\n\n> Perhaps all I'm asking for is a way of dropping the obsmarker between `B` and `B'`. I don't know what the best UI for that would be, though. For now, I guess I'll use `hg strip`.\n\nStripping obsmarkers (and changesets) gets tricky quickly as their might continue to exist elsewhere. [issue5267](https:\/\/bz.mercurial-scm.org\/show_bug.cgi?id=5267) is a good example. There is already a couple of ways to do it (hg strip or hg debugobsolete) but it is currently confined into advanced commands. Before smoothing special case that could benefit stripping (or equivalent feature), it is important to deal with the UI for the main use-case. The use-case that solves both local and distributed evolution with the same command set. We want this commands set to comes first as we know it will be necessary. We can add more advanced commands and concept to deal with stripping afterward.\n\n\nLet me clarify that last part: imagine two commands (or command set, or concepts):\n\n # Command-A handles cases for both local and distributed evolution,\n # Command-B only handles local evolution, but deal with a corner case a bit later.\n\n\nIf we introduce Command-A early, we can foster a good user experience that will be the same for local and distributed case. This makes the \"step\" to distributed usage simple and painless. The overall user experience and other commands will make sure they work smoothly with Command-A. Later, we can introduce Command-B that will deal with specialized cases were Command-A is lacking. Since Command-A is already covering the main use-cases well, Command-B can focus on dealing with the specialized cases only. Each command has clear responsibilities.\n\nOn the other hand, introducing Command-B first will create a user experience that does not cover all of the main use-cases. The later arrival of Command-A will introduce an overlap in responsibilities confusing to users. In addition, it will create a problematic step to move from the local experience to the distributed one. Users will have to \"forget\" their previous usage to be able to get the better of Mercurial, this will create more confusion.","author":"lothiraldan","id":"74342","dateCreated":"1539204897","dateModified":"1539204897"},{"type":"comment","comment":"Here's a case I just ran into where I would have liked to de-obsolete a commit:\n\n1.

We have submitted code recently to detect when an obsolete changeset is re-added, but again we don't know if it is accidentally or intentionally. The safe path here is to inform the user about suspicious situations and give them the tool to explicitly restore changesets they want to be restored.

I weary of it, because it's not a new argument, it's just blind devotion to the initial design without any attempt at reflection if we can do better.\n\n\nSince I joined Octobus, I've witnessed the exploration of all the remaining uncharted territories and solving of most of the resulting associated challenges. In particular, some important aspects of distributed evolution: instabilities resolutions and efficient obsmarkers exchanges have been solved and have working implementations used on a daily basis. We did alter the initial design when deemed so by new information from exploration or feedback of evolve users.\nDuring these developments, we did not find reasons to challenge the obsolescence core concepts. They, in fact, proved a useful help to build solutions to the distributed evolution challenges. To name a few of these progress and design changes: vocabulary renaming, the missing commands for history exploration and reviving, the new discovery protocol and more recently how to track fold in obsmarkers.\n\nIn a similar way, the numbers and types of distributed evolution users have grown and we had more and more opportunity to exchange with them. We base our plans on more than \"some people using it without complains\". They are a diverse and large corpus of people we have been talking to and studied their workflows. Here again, core concepts, in particular, the global state and instabilities are things that, practically helps teams to use distributed evolution workflows and newcomers to get a good grasp of it. Important behavior designed and tested in the past 5 years, like the exchange behavior, have been battle tested and real people rely on them in their day to day workflow.\n\nSo, it might seem like the same argument, but it is actually a stronger one. The data to back it kept growing in the past couple of years.\n\nIf you need more details, check our recent blog post about evolution: https:\/\/octobus.net\/blog\/2018-09-03-evolve-status-2018-08.html\n\n> I don't dispute that evolution as currently implemented is a good thing, but I feel like there's room for significant improvement while simultaneously simplifying the exchange algorithms. Care to try and convince me why I'm wrong, without anecdotal \"many people use this and haven't complained\" arguments?\n\n\nSure, the proposal in this PoC (\"unobsolete\" all re-added changesets) break basic distributed evolution workflow very quickly. Here are small examples among many. They display simple draft changesets roundtrips:\n\n- Example A:\n\n        - I am working on a repository with a changeset A that is present also on my default server\n        - I amend A into A'\n        - I pull from my default server, the server doesn't know yet that A has been rewritten into A'. A is sent by the server.\n        - A is hidden before the pull. Getting A to be visible again would be confusing for me as I would now have both A and A' \"alive\" at the same time.\n \n- Example B:\n\n        - I am working on a repository with a changeset A that is present also on my default server\n        - I amend A into A'\n        - One of my coworkers push a changeset B on top of A to the server\n        - I pull from my default server\n        - I receive both B and A, and I have all the needed information to stabilize B and continue my work. I don't want A to become \"unobsolete\" on pull.\n\nWe can provide other examples if needed.\n\nCould you give some details about the improvements that you suggest and that what kind of core changes they would require and their effects on distributed evolution?\n","author":"lothiraldan","id":"72403","dateCreated":"1538147960","dateModified":"1538147960"},{"type":"comment","comment":">>!

I had a couple of important things to get out of the way before I could turn my attention to this.\n\nI reached out to Ryan and he sent me the code he wrote at the 4.6 Sprint. I made it available here to support the discussion: https:\/\/phab.mercurial-scm.org\/D4479. The core differences in his approach are to filter out obsmarkers affecting the \"re-pulled\" nodes instead of \"stripping\" those markers. The main benefit is to avoid information loss. Stripping markers will break the evolution history, preventing user to benefit from it. Filtering markers out mean that the history will be fully restored if the affected changeset get obsolete again. It can be triggered by the same events.This is a pure implementation detail, having the same user-level effect than the behavior proposed in this Proof of Concept series.\n\nRegarding the implementation of this series, I feel like the current detection code needs to move at a higher level. Having changegroup aware of obsmarkers at such a low level seems wrong and can lead to consistency issues if the bundle contains  obsmarkers. An alternative approach would be to keep track of redundant incoming nodes during changegroup processing (on the transaction object as we are already doing for all new nodes), and process that list at the end of the transaction. We'll give a shot at such implementation, it is useful in other scenarios.\n\nTo take a step back, I'm wondering what's the end goal?

Although webcommands are currently using this\ndecorator, it does not behave as intended. Using the decorator\nshould record the name of the decorator in a `commands` dict,\nand when a request arrives to hgweb the correct function to\ncall should be resolved from that dict.\n\nIn the current implementation the command is added to the\ncommands dict, but when hgweb attempts to resolve the function\nwhile processing a request, it instead looks for an attribute\nwith the same name attached to the `webcommands` module. To\nsummarize, a command 'commandname' should be resolved from\n\n    `mercurial.hgweb.webcommands.commands['commandname']`\n\nbut is instead being resolved from\n\n    `mercurial.hgweb.webcommands.commandname`\n\nThe decorator appears to be working on the core webcommands\n(such as log, rev, file) however this is because those\ncommands are defined with the same name in the underlying\nPython function.\n\nThis commit changes hgweb_mod.py to resolve the function used\nfrom webcommands to come from the `commands` dict in the\n`webcommands` module. Due to the change in how webcommands\nare resolved, a `wrapwebcommand` function is also added, which\nwraps a webcommand by applying the wrapper as a partial function\nand overwrites the existing function in the `commands` dict.\n\nWrapped webcommands in shipped extensions and hgweb tests\nare changed to use the fixed decorator and `wrapwebcommand`\nfunction.","testPlan":"","lineCount":"48","dependsOn":[],"reviewers":[],"ccs":["foozy","indygreg","mercurial-devel"],"actions":[{"type":"comment","comment":"Sorry, I overlooked delivery error of reply to phabricator.\n\nThis is re-sending of the reply at Sat, 18 Aug 2018 15:18:10 +0900,\nwhich was cc-ed to mercurial-devel@mercurial-scm.org.\n\nAt Wed, 15 Aug 2018 19:00:51 +0000,\nsheehan (Connor Sheehan) wrote:\n[snip]\n> diff --git a\/mercurial\/hgweb\/hgweb_mod.py b\/mercurial\/hgweb\/hgweb_mod.py\n> --- a\/mercurial\/hgweb\/hgweb_mod.py\n> +++ b\/mercurial\/hgweb\/hgweb_mod.py\n> @@ -354,7 +354,7 @@\n>                  cmd = cmd[style + 1:]\n>  \n>              # avoid accepting e.g. style parameter as command\n> -            if util.safehasattr(webcommands, cmd):\n> +            if cmd in webcommands.commands:\n>                  req.qsparams['cmd'] = cmd\n>  \n>              if cmd == 'static':\n> @@ -416,15 +416,15 @@\n>  \n>                  res.headers['ETag'] = tag\n>  \n> -            if cmd not in webcommands.__all__:\n> +            if cmd not in webcommands.commands:\n>                  msg = 'no such method: %s' % cmd\n>                  raise ErrorResponse(HTTP_BAD_REQUEST, msg)\n>              else:\n>                  # Set some globals appropriate for web handlers.

How does that sound?\n> (@jeffpc I am not sure I explained this correctly, it will be great if you can chime in.)\n\nI don't really care about the actual string value, I just think it is a good storage design practice to have every on-disk structure contain a magic value of some sort.  (Beware, I have a storage background and therefore opinions about these things... ;) )  This makes it easier to do all sort of data recovery should the need arise.  E.g.,\n\n  - if you know that a random file (e.g., from lost+found) is a hg state file, you can ignore\/delete it and just reclone your repos\n  - hg can detect some corruption better, and depending on the state file regenerate it or error out\n  - hg developers can more easily sort out what's what when looking at buffers\/files\/etc.\n  - as an added bonus, the magic can be used for format versioning\n\n\nFWIW, the three major things that I consider essential to good on-disk structures:\n\n  # magic numbers - see above\n  # checksums - possibly two checksums: one for the header and one for the payload\n  # back-pointers - see below\n\nBack-pointers allow you to tie the file\/buffer into the bigger context - be it which state file it is, or which repository it belongs to.

All filesystem operations should take a `Path` instance to operate on. This is the only way to cleanly round trip filenames between the OS, the application, and back to the OS. That leaves us with the hard problem of normalizing Mercurial's storage representation of paths (bytes) with the operating system's. But this world is strictly better than today, where we lose path data from the OS because we use POSIX APIs.\n\nFWIW, Python 3 rewrote the I\/O layer to use Win32 APIs everywhere. Combined with the `pathlib` types, I'm pretty sure Python 3 can round trip paths on Windows. I also think Rust's path type(s) have OS-dependent functionality.","author":"indygreg","id":"43990","dateCreated":"1520534077","dateModified":"1520534077"},{"type":"comment","comment":">>!

The dirstate code is some of the most optimized code in Mercurial. There are some gnarly Python C hacks to make it fast. Some of those tricks involve using special system calls to walk directories to minimize the number of system calls. I'm not sure if the crate you imported has those optimizations. (I wouldn't be surprised either way.) I wouldn't worry too much about performance at this juncture. But I suspect we could make the Rust code another 50% faster with some tweaking. It would also be interesting to test on a larger repo, say https:\/\/hg.mozilla.org\/mozilla-unified. Also, I believe there are hooks in the dirstate code to use Watchman (fsmonitor). Those hooks are critical in order to achieve peak performance on large repositories.\n\nSince you seem to be proficient at writing lots of Rust code, if you are looking for another project, may I suggest porting `chg` to Rust?

PyPy obviously uses CFFI. I think the ideal outcome is we can write Rust that exposes a C API and use CFFI natively on PyPy and something like `cbindgen` + `Milksnake` to auto-generate a CPython extension that acts as a wrapper around the C API exposed by Rust. I'm not sure if anyone has invented this exact wheel yet. If not, it's probably faster to use `rust-cpython`.

It is generally useful to have Rust that isn't bound to Python because it will facilitate reuse outside of Python contexts. For example, someone could implement a Mercurial wire protocol server in pure Rust without needing to worry about Python. Of course, we're likely to encounter areas where we really want tight coupling in order to achieve optimal performance in Python. So we may have to design APIs on the pure Rust side to facilitate CPython use. I'm OK with that.\n\nAs for how many crates to have, I don't have super strong opinions. I could see us putting every little component\/subsystem in its own crate. I could also see us putting everything in one large crate. I don't think it is worth deciding at this early juncture. API design and ability to be reused outside its originally intended purpose is the important property to strive for. I think that has more to do with how the code is authored rather than which crates things are in.\n\nA missing piece of this patch is the build system and module loader integration. We have a \/\/module policy\/\/ that dictates which implementation of a Python module we use. We probably want to introduce a `rust` policy that uses Rust-based modules where available and falls back to the `cext` modules\/policy if a Rust module isn't available. We also need to figure out how to integrate Rust into `setup.py`. But I think the build system bit can be deferred until we're actually ready to ship Rust, which is still a bit of ways off. I'm happy for the workflow to be \/\/run cargo in order to load Rust modules\/\/ for the time being. But if you can implement `Makefile` and\/or `setup.py` integration to build these Rust extensions, that would be awesome.","author":"indygreg","id":"34484","dateCreated":"1517947275","dateModified":"1517947275"},{"type":"comment","comment":"I am open to the three-crates plan.

The remotefilelog extensions - which\nimplements various aspects of partial clone - adds a handful of\nwire protocol commands:\n\ngetflogheads\n   Obtain heads of a filelog\ngetfile\n   Obtain data for an individual file revision\ngetfiles\n   Batch version of getfile\ngetpackv1\n   Obtain a \"pack file\" containing index and data on multiple\n   files\n\n(among others)\n\nRecently, the wire protocol has gained support for \"obtain repository\ndata\" in the form of overloading the \"getbundle\" wire protocol\ncommand. This is arguaby OK in the context of \"all data is attached\nto bundles\" and \"bundles are a self-contained representation of\ncomplete repository data.\" But partial clone invalidates these\nassumptions because in a partial clone world, we no longer can assume\nthings like \"the client has all the base revisions.\"\n\nIn a partial clone world, we'll need wire protocol commands that allow\nclients to obtain specific pieces of data with vastly different\naccess patterns. For example, a client may want to obtain \"index\"\ndata but keep the fulltext data on the server. Or vice-versa. Or a\nclient may wish to fetch all revisions of a specific file but only\nthe latest revision of another. These access patterns will be\ndifficult to shoehorn into single, powerful commands (like\n\"getbundle\"). Even if we could, doing that isn't wise from a server\nimplementation perspective because it makes implementing scalable\nservers hard. We want server-side commands to be small and simple\nso alternate server implementations can come into existence more\neasily.\n\nThis is one reason why the frame-based wire protocol I'm implementing\nsupports command pipelining and out-of-order responses. This\nproperty will enable clients performing complex operations to send\ncommand streams containing dozens or even hundreds of small command\nrequests to servers.\n\nAnyway, this commit implements an experimental wire protocol command\nfor \"get files data.\" Essentially, you give it a changeset revision\nyou are interested in and it spits back all the files and their data\nin that revision, as fulltexts.\n\nThis command is just one way a server could emit data for files.\nA variation of this command that accepts specific file paths and nodes\nwhose data is to be retrieved would also be useful. And I imagine we'll\neventually implement that. It would also be useful to emit index\ndata. Or have each file blob be individually compressed. (Right now\ncompression is performed on the whole stream because that's how the\nwire protocol currently works - but I have plans to evolve the frame\nbased protocol to do new and novel things here.)\n\nI'm not even sure this variation of the wire protocol command is a\ngood one to have! One reason I want to start with this command is\nthat it seems like a useful primitive. For example, with this\ncommand, one could build a client that is able to realize a working\ndirectory from a single wire protocol request: you can literally\nstream the response to this command and turn the data into files on\nthe filesystem with minimal stream processing!\n\nAs implemented, this command is effectively a benchmark of revlog\nreading and\/or compression. On the mozilla-unified repository when\noperating on revision c488b8d0e074efb490ebca32db68eb77871bfd2f (a\nrecent revision of mozilla-central, the head of Firefox development),\nmy i7-6700K yields the following:\n\n* no compression: 1478MB;  ~94s wall; ~56s CPU\n* zstd level 3:    343MB;  ~97s wall; ~57s CPU\n* zlib level 6:    367MB; ~116s wall; ~74s CPU\n\nFor comparison, `hg bundle --base null -r c488b8d0e0 -t zstd-v2`\n(which approximates what `hg clone -r` would be doing on the server)\nyields:\n\n  1397MB; ~624s wall; ~225s CPU\n\nOf course, these are vastly different operations. But this does\ndemonstrate that if your use case of version control is \"check out\nrevision X\" and you were previously relying on `hg clone` [without\nstream clone bundles] to do that, this wire protocol command\nis overall much more efficient on servers. It's worth noting that\nthe use case of version control for many automated systems *is*\n\"check out revision X.\" So I think providing a clone mode that can\nrealize a working copy as fast as possible is a worthwhile feature\nto have!","testPlan":"","lineCount":"335","dependsOn":[],"reviewers":[],"ccs":["mercurial-devel"],"actions":[{"type":"comment","comment":"This needs rebasing.
