repoview: do not include filter name in name of proxy class The type object is shared across all filters. I'll add __repr__() instead.

rewriteutil: use precheck() in uncommit and amend commands Differential Revision: https://phab.mercurial-scm.org/D1526

rewriteutil: add a precheck function to check if revs can be rewritten The precheck function is intended to be used before we start rewritting changesets. Differential Revision: https://phab.mercurial-scm.org/D1503

rewriteutil: add utility function to check if we can create new unstable cset This patch adds a new file which will contain utility functions related to rewritting changesets. It also adds a utility function to check if the rewritting operation creates new unstable changesets and are we allowed to create them. This rewriteutil.py introduced in this patch and the utility functions added in the upcoming patches exists in the evolve extension are being ported from there.

test-run-tests: do not rebuild hg in the test d600bda4 and fc0f3ed0 added code to call `$PYTHON run-tests.py ...`. That will rebuild hg, is slow and could have other crashes from setup.py, like: Unable to find a working hg binary to extract the version from the repository tags Therefore use `run-tests.py -l` instead.

remotenames: consider existing data while storing newer data Previously reviewed as D1357. Differential Revision: https://phab.mercurial-scm.org/D1551

remotenames: add functions to read remotenames data from .hg/remotenames/ This patch functions which can be used to read remotenames data from .hg/remotenames/. The logic for the function which reads the remotenames file is taken from the remotenames extension. Previously reviewed as D940. Differential Revision: https://phab.mercurial-scm.org/D1550

remotenames: add test showing overwriting on remotenames data The current storage logic every time overwrites the existing data with the new data. This patch adds test to demonstrate that. To fix this, we need to add logic to read existing remotenames data and merge with existing data which will be added in upcoming changesets. Previously reviewed as D1356. Differential Revision: https://phab.mercurial-scm.org/D1549

remotenames: add functionality to store remotenames under .hg/hgremotenames/ This patch moves the functionality from remotenames extension to store remotenames to core. Storage format used by remotenames extension: A single file `.hg/remotenames` with an entry in each line where each line is of format: `node nametype remotepath/name` where nametype is either 'bookmarks' or 'branches'. This was not the best way to store data, so while moving to core the storage format was changed but yet not the final format. The storage format used by core after this patch will be: * A file for each type of name i.e. bookmarks and branches in .hg/remotenames/ directory * A version number on the top of the file. The version for current format is 0. * An entry in each line where each line is of the format `node\0remotepath\0name` The logic to sync with existing remotenames file and saving journals and other related things will be moved to core in next patches incrementally. Thanks to Ryan, Augie and Durham for suggestions on storage format. Previously reviewed as D939. Differential Revision: https://phab.mercurial-scm.org/D1548

remotenames: move function to pull remotenames from the remoterepo to core This patch is the first patch of the series moving functionality from hgremotenames extension to core. There are lot of functionality in the extension which in the end enables us to store branch heads and bookmarks location on a server from which we are pulling or cloning from. This will help us in creating a better bookmark workflow where we can show user that a certain server has this bookmarks at this node. It will also introduce namespaces related to remote bookmarks and remote branches. This patch moves the functionality to pull branches and bookmarks from a server from which we are pulling to core behind config option `experimental.remotenames`. This patch adds a test which helps us to analyse whether things are working or not. We are currently writing things to ui, we will write information to files in upcoming patches.

test: fix bad replace for fixing pure-only build When we replaced the patterns, glob was removed on the fixed line, it was a mistake and caused the pure-only build to fails. Differential Revision: https://phab.mercurial-scm.org/D1592

test: fix common-pattern for pure variant The $USUAL_COMPRESSIONS$ value that was taken was not compatible with the pure variant systems as zlib seems to not be available in these case. Differential Revision: https://phab.mercurial-scm.org/D1562

tests: add a substitution for EADDRINUSE/WSAEADDRINUSE messages I suspect some more of these are globbed out, so this is a bit of future proofing.

tests: add a substitution for ECONNRESET/WSAECONNRESET messages

tests: add a substitution for ENOTDIR/ERROR_PATH_NOT_FOUND messages

tests: add a substitution for ENOENT/ERROR_FILE_NOT_FOUND messages Automatic replacement seems better than trying to figure out a check-code rule. I didn't bother looking to see why the error message and file name is reversed in the annotate and histedit tests, based on Windows or not. I originally had this as a list of tuples, conditional on the platform. But there are a couple of 'No such file or directory' messages emitted by Mercurial itself, so unconditional is required for stability. There are also several variants of what I assume is 'connection refused' and 'unknown host' in test-clone.t and test-clonebundles.t for Docker, FreeBSD jails, etc. Yes, these are handled by (re) tags, but maybe it would be better to capture those strings in order to avoid whack-a-mole in future tests. All of this points to using a dictionary containing one or more strings-to-be-replaced values.

setup: only write some autogenerated files if they change Without this change, setup.py always writes some files on every invocation. This prevents some builds from being a no-op when they should. And, since times can sneak into generated .pyc files, this prevents file content from being deterministic between builds. As part of the refactor, we treat file content as bytes. The only potential regression from this would be if some tool is looking at mtimes of the changed files to determine if further action should be taken. But I don't think anything critically important is keyed off the mtimes of these specific files. Differential Revision: https://phab.mercurial-scm.org/D1580

fancyopts: fix handling of "--" value in earlygetopt()

fancyopts: use getopt.gnu_getopt() The issue described in the docstring has been fixed since Python 20ab2260dc93, which is in 2.7. https://hg.python.org/cpython/rev/20ab2260dc93 https://bugs.python.org/issue4458 This fixes the handling of '--' value.

dispatch: replace _earlygetopt(strip=True) with new parser The execution order in cmdalias.__init__() is adjusted to set stripped args to self.givenargs, which is no longer updated in place.

dispatch: replace _earlyreq*() with new fancyopts-based parser

dispatch: alias --repo to --repository while parsing early options This prepares for replacing old _early*opt() functions. My initial attempt was to extend options table to support 'repository|repo' syntax. It worked, but seemed too invasive. So I decided to add an optional argument to fancyopts() instead. This also changes the nevernegate dict to be keyed by a canonical_name, not by an option-name for clarity.

spartan: render changesets server-side on /graph page

paper: render changesets server-side on /graph page

hgweb: only include graph-related data in jsdata variable on /graph pages (BC) Historically, client-side graph code was not only rendering the graph itself, but it was also adding all of the changeset information to the page as well. It meant that JavaScript code needed to construct valid HTML as a string (although proper escaping was done server-side). It wasn't too clunky, even though it meant that a lot of server-side things were duplicated client-side for no good reason, but the worst thing about it was the data format it used. It was somewhat future-proof, but not human-friendly, because it was just a tuple: it was possible to append things to it (as was done in e.g. 270f57d35525), but you'd then have to remember the indices and reading the resulting JS code wasn't easy, because cur[8] is not descriptive at all. So what would need to happen for graph to have more features, such as more changeset information or a different vertex style (branch-closing, obsolete)? First you'd need to take some property, process it (e.g. escape and pass through templatefilters function, and mind the encoding too), append it to jsdata and remember its index, then go add nearly identical JavaScript code to 4 different hgweb themes that use jsdata to render HTML, and finally try and forget how brittle it all felt. Oh yeah, and the indices go to double digits if we add 2 more items, say phase and obsolescence, and there are more to come. Rendering vertex in a different style would need another property (say, character "o", "_", or "x"), except if you want to be backwards-compatible, it would need to go after tags and bookmarks, and that just doesn't feel right. So here I'm trying to fix both the duplication of code and the data format: - changesets will be rendered by hgweb templates the same way as changelog and other such pages, so jsdata won't need any information that's not needed for rendering the graph itself - jsdata will be a dict, or an Object in JS, which is a lot nicer to humans and is a lot more future-proof in the long run, because it doesn't use numeric indices What about hgweb themes? Obviously, this will break all hgweb themes that render graph in JavaScript, including 3rd-party custom ones. But this will also reduce the size of client-side code and make it more uniform, so that it can be shared across hgweb themes, further reducing its size. The next few patches demonstrate that it's not hard to adapt a theme to these changes. And in a later series, I'm planning to move duplicate JS code from */graph.tmpl to mercurial.js and leave only 4 lines of code embedded in those <script> elements, and even that would be just to allow redefining graph.vertex function. So adapting a custom 3rd-party theme to these changes would mean: - creating or copying graphnode.tmpl and adding it to the map file (if a theme doesn't already use __base__) - modifying one line in graph.tmpl and simply removing the bigger part of JavaScript code from there Making these changes in this patch and not updating every hgweb theme that uses jsdata at the same time is a bit of a cheat to make this series more manageable: /graph pages that use jsdata are broken by this patch, but since there are no tests that would detect this, bisect works fine; and themes are updated separately, in the next 4 patches of this series to ease reviewing.
