== Mercurial 4.6 (2018-05-06) == [[Release4.6|Full release notes]] are available. This is a regularly-scheduled quarterly feature release. === New Features === ==== pullbundles ==== Pullbundles allow the server to answer client requests using pre-built bundles. This is different from the existing clonebundle feature: * pullbundles can be used for both the initial clone and later pull operations * pullbundles can be used incrementally, i.e. to cover the changes up to the start of the current month as one bundle and the remaining changes as second bundle * the bundle is transferred inline as part of the existing connection without a secondary server Pullbundles are only used for clients running Mercurial 4.6 as well. ==== push ==== If 'server.streamunbundle' option is enabled, the server will directly apply the changes send by the changes. This avoids potentially large temporary files on the server side. It can also prevent concurrent pushes. ==== notify extension ==== The 'maxdiffstat' option can be used to truncate long file lists similar to 'maxdiff' for the patch part of the email. ==== hgweb ==== hgweb now shows date and user for operations that resulted in obsolete commit(s). For unstable commits, it shows the exact reason why they are considered unstable. `Server:` header is now configurable using `web.server-header` option. ==== templates ==== A new template keyword 'reporoot' which shows the root directory of the current repository. A new template function 'mailmap' which maps author fields based on values in a .mailmap file. ==== Other notable features ==== * revset: parse error now shows a hint where the error occurred * templates: parse error now shows a hint where the error occured * forget: new '--dry-run' and '--interactive' flags * copyfile: preserve stat info (mtime, etc.) when doing copies/renames * bundle2 format is documented and can be found using 'hg help internals.bundle2' |

* Support for connecting to Mercurial servers older than 0.9.1 has been removed. * Working-directory commands now respect "-X PATTERN" no matter if PATTERN matches explicitly-specified FILEs. For example, "hg add foo -X foo" no longer add the file "foo". * Support for the experimental manifestv2 format has been removed, as it was never completed and failed to meet expectations. * '{' in output filename passed to archive/cat/export is taken as a start of a template expression. * The HTTP wire protocol server no longer accepts the "cmd" argument to control which command to run via HTTP POST bodies. The "cmd" argument must be specified on the URL query string. * Hgweb no longer reads form data in POST requests from multipart/form-data and application/x-www-form-urlencoded requests. Arguments should be specified as URL path components or in the query string in the URL instead. * Query string shorts in hgweb like "?cs=@" have been removed. Use URLs of the form "/:cmd" instead. * The HTTP client no longer accepts text/plain and application/hg-changegroup Content-Type values as a valid Mercurial command response. These should only be encountered on pre 1.0 Mercurial servers. === Performance Improvements === * 'hg manifest --all' is likely slower due to changing its implementation to respect storage interface boundaries. If you are impacted by this regression in a meaningful way, please make noise on the development mailing list and it can be dealt with. * 'hg diff' is much faster for larger repositories. 40% improvements have been reported. Other operations using diffs like hgweb also benefit. === Bug Fixes === * grep: fixes erroneous output of grep in forward order (Bts:issue3885) * dirstate: drop explicit files that shouldn't match (BC) (Bts:issue4679) * procutil: rewrite popen() as a subprocess.Popen wrapper (Bts:issue4746) (API) * bookmarks: test for exchanging long bookmark names (Bts:issue5165) * templater: drop symbols which should be overridden by new 'ctx' (Bts:issue5612) * clone: updates the help text for hg clone -{r,b} (Bts:issue5654) * bundle: updates the help text for hg bundle (Bts:issue5744) * histedit: make histedit's commands accept revsets (Bts:issue5746) * releasenotes: replace abort with warning while parsing (Bts:issue5775) * context: skip path conflicts by default when clearing unknown file (Bts:issue5776) * templatekw: switch most of showlist template keywords to new API (Bts:issue5779) * rebase: do not consider extincts for divergence detection (Bts:issue5782) * revert: use an exact matcher in interactive diff selection (Bts:issue5789) * subrepo: don't attempt to share remote sources (Bts:issue5793) * lfs: respect narrowmatcher when testing to add 'lfs' requirement (Bts:issue5794) * showconfig: allow multiple section.name selectors (Bts:issue5797) * annotate: do not poorly split lines at CR (Bts:issue5798) * convert: avoid closing ui.fout in subversion code (Bts:issue5807) * setdiscovery: back out changeset 5cfdf6137af8 (Bts:issue5809) * fsmonitor: layer on another hack in bser.c for os.stat() compat (Bts:issue5811) * notify: access the initial revision on an unfiltered repository (Bts:issue5821) * rebase: fix issue 5494 also with --collapse * date: fixed a bug in parsing months like 'Feb 2018', 'Apr 2018' * diffhelper: rename module to avoid conflicts with ancient C module (Bts:issue5846) * infinitepush: ensure fileindex bookmarks use '/' separators (Bts:issue5840) * import: fix crash on --exact check of empty commit (Bts:issue5702) * hgweb: reuse body file object when hgwebdir calls hgweb (Bts:issue5851) * debugcolor: fix crash by empty styles (Bts:issue5856) * hgweb: discard Content-Type header for 304 responses (Bts:issue5844) * hgweb: allow Content-Security-Policy header on 304 responses (Bts:issue5844) * paper: don't register click handlers with inline javascript (Bts:issue5812) * httppeer: detect redirect to URL without query string (Bts:issue5860) * filelog: don't crash on invalid copy metadata (Bts:issue5748) === New experimental features === Each release there are lot of new features added which are hidden under the EXPERIMENTAL tag as the behavior may change in future or the feature is not complete yet. The experimental features added in this cycle are: ==== narrow extension ==== Allows to create clones which fetch history data for only a subset of files. This experimental extension is now distributed with Mercurial. ==== remotenames extension ==== Shows `remotebookmarks` and `remotebranches` in the UI. This experimental extension is now distributed with Mercurial. ==== infinitepush extension ==== Allows to store some pushes in a remote blob store on the server and to serve commits from remote blob store. The revisions are stored on disk or in everstore, the metadata are stored in sql or on disk. This experimental extension is now distributed with Mercurial. ==== fix extension ==== Allows to rewrite file content in changesets or working copy. For example, automatically applying formatting fixes to modified lines of code. This experimental extension is now distributed with Mercurial. ==== lfs extension ==== An alternative to the largefiles extension, which uses the git-lfs protocol. This experimental extension is now distributed with Mercurial. |
* The infinitepush extension is believed to be unused, and will be deleted at the end of 2020 unless users contact mercurial-devel@mercurial-scm.org. * 'hg grep' now searches working copy file contents by default. We recognize this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior. |

* Content from mercurial.hgweb.protocol has been moved to mercurial.wireprotoserver. * Content from mercurial.sshserver has been moved into mercurial.wireprotoserver. * sshserver no longers looks for wire protocol command handlers in methods named `do_<command>`. Use `@wireproto.wireprotocommand` to declare wire protocol command handler functions. * Log-related utility functions has been renamed as follows: - cmdutil.loglimit -> logcmdutil.getlimit - cmdutil.diffordiffstat -> logcmdutil.diffordiffstat - cmdutil._changesetlabels -> logcmdutil.changesetlabels - cmdutil.changeset_printer -> logcmdutil.changesetprinter - cmdutil.jsonchangeset = logcmdutil.jsonchangeset - cmdutil.changeset_templater -> logcmdutil.changesettemplater - cmdutil.logtemplatespec -> logcmdutil.templatespec - cmdutil.makelogtemplater -> logcmdutil.maketemplater - cmdutil.show_changeset -> logcmdutil.changesetdisplayer - cmdutil.getlogrevs -> logcmdutil.getrevs - cmdutil.getloglinerangerevs -> logcmdutil.getlinerangerevs - cmdutil.displaygraph -> logcmdutil.displaygraph - cmdutil.graphlog -> logcmdutil.graphlog - cmdutil.checkunsupportedgraphflags -> logcmdutil.checkunsupportedgraphflags - cmdutil.graphrevs -> logcmdutil.graphrevs - cmdutil._makenofollowlogfilematcher -> logcmdutil._makenofollowfilematcher * The following deprecated methods have been removed from context, with replacements: - unstable() -> orphan() - bumped() -> phasedivergent() - divergent() -> contentdivergent() - troubled() -> isunstable() - troubles() -> instabilities() * The following deprecated methods have been removed from obsolete, with replacements: - _addprecursors() -> _addpredecessors() - obsstore.precursors -> obsstore.predecessors - allprecursors() -> obsutil.allprecursors() - allsuccessors() -> obsutil.allsuccessors() - marker() -> obsutil.marker - getmarkers() -> obsutil.getmarkers() - exclusivemarkers() -> obsutil.exclusivemarkers() - foreground() -> obsutil.foreground() - successorssets() -> obsutil.successorsset() - unstable() -> orphan() - bumped() -> phasedivergent() - divergent() -> contentdivergent() * The following deprecated methods have been removed from obsutil: `marker.precnode()` and `allprecursors()`. Use `marker.prednode()` and `allpredecessors()` instead. * `beginparentchange()` and `endparentchange()` have been replaced by the `parentchange` context manager. * The deprecated `localrepo.walk()` has been removed, and replaced by `repo[node].walk()`. * The following deprecated methods have been removed from bookmarks: `__setitem__()`, `__delitem__()`, `update()`, and `recordchange()`. Use `bookmarks.applychanges()` instead. * The `cmdutil._revertprefetch()` hook point for prefetching stored files has been replaced by the command agnostic `cmdutil._prefetchfiles()`. The new function takes a list of files, instead of a list of lists of files. * `sshpeer.sshpeer.__init__` now receives arguments describing an existing connection instead of creating a connection itself. * `sshpeer.sshpeer` renamed to `sshpeer.sshv1peer`. * `wireproto.pushres` and `wireproto.pusherr` now explicitly track stdio output. * `redirect()` and `restore()` have been removed from the wire protocol handler interface. Use `mayberedirectstdio()` instead. * The `_client()` method of the wire protocol handler interface has been renamed to `client()`. * Wire protocol command handlers now return a `wireprototypes.bytesresponse` instead of a raw bytes instance. Protocol handlers will continue handling bytes instances. However, any extensions wrapping wire protocol commands will need to handle the new type. * SSH protocol handler now advertises its name internally as "ssh-v1" instead of "ssh." * File prefetching is now handled by registering a callback with `scmutil.fileprefetchhooks`. * HTTP protocol handlers now advertises its internal name as "http-v1" instead of "http". * `context.basectx` no longer implements `__int__`. Context instances will no longer cast to ints. Consumers should call `ctx.rev()` instead. * `templatekw.showdict()` and `showlist()` are deprecated in favor of new `(context, mapping)` API. Switch the keyword function to new API and use `templatekw.compatdict()` and `compatlist()` instead. * `hgweb_mod.perms` and `wireproto.permissions` have been removed. Wire protocol commands should declare their required permissions in the `@wireprotocommand` decorator. * The WSGI request object no longer exposes a `form` attribute containing parsed query string data. Use the `qsparams` attribute instead. * `hgweb.hgweb_mod.permhooks` no longer take a `wsgirequest` instance as an argument. * hgweb `@webcommand` functions must use the new response object passed in via "web.res" to initiate sending of a response. The hgweb WSGI application will no longer start sending the response automatically. * Various helper functions in hgweb.webutil no longer accept a templater instance. Access the templater through the "web" argument instead. * Various functions in hgweb.webutil now take a modern request object instead of "wsgirequest". * `@webcommand` functions now only receive a single argument. The request and templater instances can be accessed via the "req" and "templater" attributes of the first argument. Note that the request object is different from previous Mercurial releases and consumers of the previous "req" 2nd argument will need updating to use the new API. * The old "wsgirequest" class for handling everything WSGI in hgweb has been replaced by separate request and response types. Various high-level functions in the hgweb WSGI applications now receive these new types as arguments instead of the old "wsgirequest" type. * The `render(mapping)` method of the templater has been renamed to `renderdefault(mapping)`. * `httppeer.httppeer.__init__` now takes additional arguments. Instances should be obtained by calling `httppeer.instance()` or `httppeer.makepeer()` instead. * The templater is no longer callable. Use `templater.generate(t, mapping)` instead of `templater(t, **pycompat.strkwargs(mapping))`. * `templatekw._showlist()` is deprecated in favor of `templateutil._showcompatlist()`, which takes `context` in place of `templ`. * Several generic string helper functions have been moved to utils.stringutil module. * The `util.Abort` alias has been removed. Use `error.Abort`. * `merge.update()` and `merge.applyupdates()` now return a class with named attributes instead of a tuple. Switch consumers to access elements by name instead of by offset. * Utility functions related to process/executable management have been moved to utils.procutil module. * localrepo.localrepository.featuresetupfuncs has been renamed to localrepo.featuresetupfuncs. * localrepo.localrepository.filterpats was renamed to localrepo.localrepository._filterpats. * Template filters should declare input data type and/or catch `AttributeError`, `ValueError`, `TypeError`, etc. as needed. See the doc of "registrar.templatefilters" for details. * "wireproto" module no longer re-exports various types used to define responses to wire protocol commands. Access these types from the "wireprototypes" module. * `filelog.parsemeta()` and `filelog.packmeta()` have been moved to the revlog module. * `procutil.popen()` no longer supports text mode I/O. * `hook.hook()` and `hook.runhooks()` may return a negative integer to denote that the process was killed by signal. * `filelog.filelog` is now a standalone class and doesn't inherit from revlog. Instead, it wraps a revlog instance at `self._revlog`. This change was made in an attempt to formalize storage APIs and prevent revlog implementation details leaking through to callers. * The `fp` argument is removed from `cmdutil.export()`. Use `cmdutil.exportfile()` instead. * `cmdutil.export()` takes a formatter as an argument. * `patch.extract()` is now a context manager. Callers no longer have to worry about deleting the temporary file it creates, as the file is tied to the lifetime of the context manager. * The wire protocol peer's `iterbatch()` for bulk executing commands has been removed. Use `peer.commandexecutor()` instead. == Mercurial 4.5.3 (2018-04-04) == This is a regularly-scheduled bugfix release. === Bug Fixes === * rebase: on abort, don't strip commits that didn't need to be rebased (Bts:issue5822) * hgweb: garbage collect on every request * amend: abort if unresolved merge conflicts found (Bts:issue5805) == Mercurial 4.5.1 / 4.5.2 (2018-03-06) == (4.5.2 was released immediately after 4.5.1 to fix a release oversight.) This is a regularly-scheduled bugfix release. === Security Fixes === All versions of Mercurial prior to 4.5.2 have vulnerabilities in the HTTP server that allow permissions bypass to: * Perform writes on repositories that should be read-only * Perform reads on repositories that shouldn't allow read access CVE-2018-1000132 has been assigned these vulnerabilities. The nature of the vulnerabilities is: 1. Wire protocol commands that didn't explicitly declare their permissions had no permissions checking done. The `web.{allow-pull, allow-push, deny_read, etc}` config options governing access control were never consulted when running these commands. This allowed permissions bypass for impacted commands. 1. The `batch` wire protocol command did not list its permission requirements nor did it enforce permissions on individual sub-commands. The implication of these vulnerabilities is that no permissions checking was performed on commands and this could lead to accessing data that `web.*` config options were supposed to prevent access to or modifying data (via wire protocol commands that can mutate data) without authorization. A Mercurial HTTP server in its default configuration is supposed to be read-only. However, a well-crafted `batch` command could invoke commands that perform writes. The `batch` write permissions bypass has been present since Mercurial 1.9. The flaw of not checking permissions for wire protocol commands that don't declare their needed permissions has been present since Mercurial 1.0. Assuming you are running a server without any custom commands provided by extensions, your exposure is unauthorized data access (if relying on the `web.*` config options to limit access) and unauthorized data mutation via the `batch` command. Server operators can detect unauthorized use of the `batch` command by looking for requests to URLs of the form `repo?cmd=batch` with arguments containing `pushkey` or `unbundle`. This may produce false positives. A more comprehensive check would decode the argument string and verify that `pushkey` or `unbundle` are command names (not values). The arguments specified via `x-hgarg-<N>` request headers can span multiple headers. So advanced attackers could hide the vulnerability by splitting a `pushkey` or `unbundle` string across multiple headers. So the only reliable way to detect if this vulnerability is being exploited is to decode these headers like Mercurial does. The format for specifying arguments is documented at https://www.mercurial-scm.org/repo/hg/file/4.5/mercurial/help/internals/wireprotocol.txt#l26. Python code for decoding headers is at https://www.mercurial-scm.org/repo/hg/file/4.5/mercurial/hgweb/protocol.py#l70. Mercurial 4.5.2 fixes these vulnerabilities by: * Performing permissions checking on all wire protocol commands, not just commands that list their permissions. * Checking permissions on sub-commands issued to the `batch` command. Wire protocol commands not declaring wire protocol permissions will be assumed to be read-write commands and a server in its default configuration (which only allows read-only access), will refuse to execute these commands. For package maintainers needing to backport the fixes, the relevant changesets from 4.5.2 are `2c647da851ed::2ecb0fc535b1`. These can be viewed online at e.g. https://www.mercurial-scm.org/repo/hg/rev/2ecb0fc535b1. The author of these commits has backports to 4.4 and 4.3 on a personal fork at https://hg.mozilla.org/users/gszorc_mozilla.com/hg. The backports for 4.4 are `a4843835c835::7cf827e5f8af` and for 4.3 are `db527ae12671::86f9a022ccb8`. To obtain these changesets, run e.g. `hg pull -r 7cf827e5f8af https://hg.mozilla.org/users/gszorc_mozilla.com/hg`. === Backwards Compatibility Changes === * The "batch" wire protocol command now enforces permissions of each invoked sub-command. Wire protocol commands must define their operation type or the "batch" command will assume they can write data and will prevent their execution on HTTP servers unless the HTTP request method is POST, the server is configured to allow pushes, and the (possibly authenticated) HTTP user is authorized to perform a push. * Wire protocol commands not defining their operation type in "wireproto.PERMISSIONS" are now assumed to be used for "push" operations and access control to run those commands is now enforced accordingly. === Bug Fixes === * fileset: don't abort when running copied() on a revision with a removed file * date: fix parsing months * setup: only allow Python 3 from a source checkout (Bts:issue5804) * annotate: do not poorly split lines at CR (Bts:issue5798) * subrepo: don't attempt to share remote sources (Bts:issue5793) * subrepo: activate clone pooling to enable sharing with remote URLs * changegroup: do not delta lfs revisions * revlog: do not use delta for lfs revisions * revlog: resolve lfs rawtext to vanilla rawtext before applying delta == Mercurial 4.5 (2018-02-01) == === New Features === ==== revert --interactive ==== The revert command now accepts the flag --interactive to allow reverting only some of the changes to the specified files. ==== Accessing hidden changesets ==== Set config option 'experimental.directaccess = True' to access hidden changesets from read only commands. ==== githelp extension ==== The `githelp` extension provides the `hg githelp` command. This command attempts to convert a `git` command to its Mercurial equivalent. The extension can be useful to Git users new to Mercurial. ==== Largefiles changes ==== * largefiles: add a 'debuglfput' command to put largefile into the store * largefiles: add support for 'largefiles://' url scheme * largefiles: allow to run 'debugupgraderepo' on repo with largefiles * largefiles: convert EOL of hgrc before appending to bytes IO * largefiles: explicitly set the source and sink types to 'hg' for lfconvert * largefiles: modernize how capabilities are added to the wire protocol === hgweb changes === hgweb now shows more information about commits: phase (if it's not public), obsolescence status (with a short explanation and links to the successors) and instabilities (e.g. orphan, phase-divergent or content-divergent). Client-side graph code has been simplified by delegating more work to the backend, so /graph page is now more in sync with /log page, visually and feature-wise. Unfortunately, this code change means that 3rd-party themes for 4.5+ are required to have `graphentry.tmpl` template available (copy it from the base theme if you don't use `%include` and then reference it in map file) and render entries in `graph.tmpl` -- look at one of the core themes to see what it needs to look like. JS functions that create graph vertices and edges are now available in `Graph.prototype`, making it possible to call the original functions from custom theme-specific functions if needed. Graph now shows different symbols for normal, branch-closing, obsolete and unstable commits, and marks currently checked out commit with a circle around its graph node. There's also now `json-graph` API endpoint that can be used for rendering commit graph in 3rd-party applications. ==== Other Changes ==== * When interactive revert is run against a revision other than the working directory parent, the diff shown is the diff to <em>apply</em> to the working directory, rather than the diff to <em>discard</em> from the working copy. This is in line with related user experiences with 'git' and appears to be less confusing with 'ui.interface=curses'. * Let 'hg rebase' avoid content-divergence by skipping obsolete changesets (and their descendants) when they are present in the rebase set along with one of their successors but none of their successors is in destination. * A new experimental config flag, 'rebase.experimental.inmemory', makes rebase perform an in-memory merge instead of doing it on-disk in the working copy. * The `HGPLAINEXCEPT` environment variable can now include `color` to allow automatic output colorization in otherwise automated environments. * A new unamend command in uncommit extension which undoes the effect of the amend command by creating a new changeset which was there before amend and moving the changes that were amended to the working directory. * A '--abort' flag to merge command to abort the ongoing merge. * An experimental flag '--rev' to 'hg branch' which can be used to change branch of changesets. * bundle2 read I/O significantly improved * bundle2 memory use significantly reduced during read * clonebundle: it is now possible to serve the clonebundle using a git-lfs compatible server. * templatefilters: add slashpath() to convert path separator to slash (Bts:issue5572) * A new experimental config flag, 'inline-color-diff', adds within-line color diff capacity * histedit: add support to output nodechanges using formatter to help with editor integrations === Backwards Compatibility Changes === * `log --follow-first -rREV`, which is deprecated, now follows the first parent of merge revisions from the specified `REV` just like `log --follow -rREV`. * `log --follow -rREV FILE..` now follows file history across copies and renames. * transaction: register summary callbacks only at start of transaction * hgweb's graph view no longer supports browsers that lack <canvas> support * hgweb: only include graph-related data in jsdata variable on /graph pages * graphlog: add another graph node type, unstable, using character `*` * remove: print message for each file in verbose mode only while using '-A' === Bug Fixes === * Bookmark, whose name is longer than 255, can again be exchanged again between 4.4+ client and servers (Bts:issue5165) * The convert extension works with bzr < 2.6.0 again (Bts:issue5733) * Mercurial will now attempt to use hardlinks on NTFS on Windows (Bts:issue4580) * The revset `x^::` is now correctly parsed as `(x^)::` instead of being an error (Bts:issue5764) * Setting the diff.noprefix configuration option no longer breaks the `--stat` flag on `hg diff` (Bts:issue5759) * `hg outgoing` now honors `:pushurl` paths from hgrc (Bts:issue5365) * log: translate column labels at once (Bts:issue5750) * patch: improve heuristics to not take the word `diff` as header (Bts:issue1879) * templater: look up symbols/resources as if they were separated (Bts:issue5699) * http and ssh: support for emitting extra debug logs about requests as they happen === API Changes === * `bundlerepo.bundlerepository.bundle` and `bundlerepo.bundlerepository.bundlefile` are now prefixed with an underscore. * Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos. * dirstate no longer provides a 'dirs()' method. To test for the existence of a directory in the dirstate, use 'dirstate.hasdir(dirname)'. * mapping does not contain all template resources. use context.resource() in template functions. * `text=False|True` option is dropped from the vfs interface because of Python 3 compatibility issue. Use `util.tonativeeol/fromnativeeol()` to convert EOL manually. * `wireproto.streamres.__init__` no longer accepts a `reader` argument. Use the `gen` argument instead. * exchange.getbundlechunks() now returns a 2-tuple instead of just an iterator. * bundle2 parts are no longer seekable by default * memfilectx: the changectx argument is now mandatory in constructor == Mercurial 4.4.2 (2017-12-01) == This is a regularly-scheduled bugfix release. === Notable changes === ==== Stricter command option parsing ==== Mercurial can now optionally parse "early" options (`-R/--repository`, `--cwd`, `--config`, `--debugger`, and `--profile`) more strictly, for more secure integration with tools that invoke 'hg' commands. Setting `HGPLAIN=+strictflags` will parse these options more strictly, which prevents them from being injected as arguments to other flags. === Bug fixes === * 'hg amend' now correctly handles deleted and removed files, as well as subrepos. (Bts:issue5732, Bts:issue5677) * largefiles now correctly handles dropped standin files when updating largefiles. * Fixed an issue with deleting symlinks to directories when ui.origbackuppath is set. (Bts:issue5731) === Performance improvements === * Improved performance in path conflict checking introduced in Mercurial 4.4. (Bts:issue5716) == Mercurial 4.4.1 (2017-11-07) == === Notable changes === * Git and Subversion subrepos have been disabled by default to mitigate a potential security risk if files overlapping with a subrepo managed to be committed to a repository. * Subrepos are now more paranoid about symlink traversal. * The share extension handles drive letters on Windows better. It is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked in to the repository in Mercurial 4.4 and earlier. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically. == Mercurial 4.4 (2017-11-01) == === Notable changes === ==== Control whitespace settings for annotation on hgweb ==== /annotate URLs on hgweb now accept query string arguments to influence how whitespace changes impact results. The arguments "ignorews," "ignorewsamount," "ignorewseol," and "ignoreblanklines" now have the same meaning as their [annotate] config section counterparts. Any provided setting overrides the server default. HTML checkboxes have been added to the paper and gitweb themes to expose current whitespace settings and to easily modify the current view. ==== Fast, heuristic copy-tracing ==== A new fast heuristic algorithm for copytracing which assumes that the files moves are either: 1. renames in the same directory 1. moves in other directories with same names You can use this algorithm by setting 'experimental.copytrace=heuristics'. This setting performs full copytracing if both source and destination branches contains non-public changesets only. ==== Other changes ==== * Estimated time is more accurate with non-linear progress * "hg status -v" can now show unfinished state. For example, when in an unfinished rebase state, "hg status -v" might show: {{{ # The repository is in an unfinished *rebase* state. # No unresolved merge conflicts. # To continue: hg rebase --continue # To abort: hg rebase --abort }}} * Added '--ignore-space-at-eol' diff option to ignore whitespace differences at line endings. * show: use consistent node length in views * show: decrease minimum displayed hash length from 5 to 4 * A new uncommit extension which provides 'hg uncommit' using which one can uncommit part or all of the changeset. This command undoes the effect of a local commit, returning the affected files to their uncommitted state. * 'hg clone --uncompressed' uses clone bundles when possible * 'hg annotate --skip' now prints a '*' on lines with skipped revisions * New 'commands.update.check' feature to adjust constraints on when 'hg update' will allow updates with a dirty working copy. * Add an experimental -L/--line-range FILE,FROMLINE:TOLINE option to 'hg log' command to follow the history of files by line range. In combination with -p/--patch option, only diff hunks within specified line range will be displayed. Feedback, especially on UX aspects, is welcome. * Print warning when fsmonitor isn't being used on a large repository === Backwards Compatibility Changes === * The config option for copytrace 'experimental.disablecopytrace' is now replaced with 'experimental.copytrace' which defaults to 'on'. If you need to turn off copytracing, add '[experimental] copytrace = off' to your config. * 'hg clone --stream' should now be used instead of --uncompressed. --uncompressed is marked as deprecated and is an alias for --stream. There is no schedule for elimination of --uncompressed. * The 'experimental.updatecheck' name for the new 'commands.update.check' feature is now deprecated, and will be removed after this release. * Mercurial subrepositories are now shared instead of cloned when the parent repository is shared. This prevents dangling subrepository references in the share source. Previously shared repositories with cloned subrepositories will continue to function unchanged. * Push no longer triggers a pushkey hook when updating phases. Use the new 'txnclose-phase' and 'txnclose-phase' hooks instead. (Applies when both server and client use version 4.4 or above). === Bug Fixes === * Core rebase algorithm has been rewritten to be more robust (Bts:issue5578, Bts:issue5630) * Creating a share of a repository with a Mercurial subrepository will now share the subrepository (Bts:issue5675) === Performance Improvements === * improved performance when many aliases are defined === API Changes === ==== remove peer.batch() ==== Replace with peer.iterbatch(). ==== Other Changes ==== * @peer.batchable can no longer emit local values * @peer.batchable functions must now yield exactly 2 values * Rename attributes on sshpeer to reflect peer API * peer.peerrepository has been removed. Use repository.peer abstract base class to represent a peer repository. * revset.stringset() now takes 'order' as the last argument. == Mercurial 4.3.3 (2017-10-01) == * Prevent crashes when clearing progress bar. (Bts:issue5684) * rebase: move bookmarks with --keep (Bts:issue5682) == Mercurial 4.3.2 (2017-09-18) == * restore compatibility with older versions of Python 2.7 by not using a bytearray with struct.unpack_from() * restore mingw compatibility for setup.py * hgwebdir: read 'web.template' untrusted (plugs potential security issue) * repair: preserve phase when not using generaldelta (Bts:issue5678) * ssh: fix flakey ssh errors on BSD systems * restore error handling behavior around certain I/O errors; the regressed behavior could result in transactions not being properly rolled back if stdio handles encountered errors (Bts:issue5658) * templatekw: choose {latesttag} by len(changes), not date (Bts:issue5659) * record: fix revert -i for lines without newline (Bts:issue5651) * mq: create non-lossy patches, also with custom global diff configuration == Mercurial 4.3 / 4.3.1 (2017-08-10) == (4.3.1 was released immediately after 4.3 to fix a release oversight.) An [[Release4.3|overview of new features]] available. This is a regularly-scheduled quarterly feature release. === Notable changes === * experimental amend extension providing the amend command * experimental sparse extension * Support for Python 2.6 has been dropped. * Bundles created by the strip extension now store phase information. It will be restored when unbundling. * The strip extension now removes relevant obsmarkers. If a backup requested (the default), the obsmarkers are stored in the backup bundle and will be restored when unbundling. * `hg show work` (from the experimental `show` extension) now displays more info * `hg show stack` is a new view for the current, in-progress changeset and others around it * Mitigation for two security vulnerabilities === CVE-2017-1000115 === Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository. === CVE-2017-1000116 === Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed. == Mercurial 4.2.3 (2017-08-10) == This was an out-of-cycle backport of security fixes from 4.3 for users stuck on Python 2.6. == Mercurial 4.2.2 (2017-07-05) == This is a regularly-scheduled bugfix release. * largefiles: avoid a crash when archiving a subrepo with largefiles disabled * rebase: also test abort from pretxnclose error * rebase: backed out changes 2519994d25ca and cf8ad0e6c0e4 (Bts:issue5610) * rebase: reinforce testing around precommit hook interrupting a rebase == Mercurial 4.2.1 (2017-6-4) == This is a regularly-scheduled bugfix release. * `hg graft` now works when grafting across merges that were problematic before ([[https://www.mercurial-scm.org/repo/hg-stable/rev/b4e1e30528c7|b4e1e30528c7]]). * A race condition in `hg status` was partially fixed (Bts:issue5584). * The message about deprecated SHA-1 hashes in the [hostfingerprints] config section now references the correct syntax for replacing them with SHA-256 hashes (Bts:issue5559). == Mercurial 4.2 (2017-5-2) == An [[Release4.2|overview of new features]] available. This is a regularly-scheduled quarterly feature release. === Notable changes === * Pager support has been moved into core and is now enabled by default. This is now controlled with the ui.paginate setting. * Note that in 4.2-rc, the ui.paginate option was named pager.enable. The old name has been dropped in the final release. If you had turned pagination off using pager.enable=False, please update your config. * Color support has also been moved into core and is now enabled by default (the ui.color setting now defaults to 'auto'). * The new experimental 'show' extension provides a way to view various information about your repository in an ergonomic way. It is deliberately designed for human consumption and not for scripting, so it doesn't carry the same [[CompatibilityRules|backward compatibility guarantees]] as other commands. See 'hg help -e show' for more information. * Mercurial now requires `setuptools` on Windows. === commands === * Pager support has been added to the 'log', 'diff', 'branches', 'files', 'status', 'summary', and 'tags' commands, as well as the '--patch', '--list', and '--stat' options of hg shelve. * bisect: set a blockedtag when running the check command * bookmarks: check HG_PENDING strictly * branches: populate all template keywords in formatter * commandserver: handle backlog before exiting * commandserver: prevent unlinking socket twice * commit: optionally strip quotes from commit template (BC) * diff: add --binary option for git mode diffs * help: add pointer how to narrow list of resolved/unresolved files (Bts:issue5469) * pager: advertise the config option in the default hgrc * pager: avoid shell=True on subprocess.Popen for better errors (Bts:issue5491) * pager: don't terminate with extreme prejudice on SIGPIPE (BC) * pager: exit cleanly on SIGPIPE (BC) * pager: improve support for various flavors of 'more' on Windows * pager: use less as a fallback on Unix * pull: abort pull --update if config requires destination (Bts:issue5528) * serve: add support for Mercurial subrepositories * status: handle more node indicators in buildstatus * status: support commands.status.relative config * update: accept --merge to allow merging across topo branches (Bts:issue5125) * verify: fix length check |
* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future. * 'mercurial.hg.updatetotally' is now more thorough about checking its 'updatecheck' keyword argument. Previously invalid values would have used the configured default updatecheck method, but now will raise ValueError. * 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'. === commands === * amend: add option to update to the current user * amend: enable support for closing the branch * amend: enable support for using the secret phase * bookmarks: actual fix for race condition deleting bookmark * bookmarks: remove changectx() method from bmstore (API) * branchmap: explicitly warm+write all subsets of the branchmap caches * import: add debug messages when parsing data from patch header * import: read X-Mercurial-Node email header to determine nodeid * log: populate keywords if specified in custom -Tjson(...) or -Tcbor(...) * merge: replace magic strings with NAMED_CONSTANTS (API) * push: support config option to require revs be specified when running push |

25.1. Backwards Compatibility Changes
* The infinitepush extension is believed to be unused, and will be deleted at
the end of 2020 unless users contact mercurial-devel@mercurial-scm.org.
* 'hg grep' now searches working copy file contents by default. We recognize
- this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior.
25.2. API Changes
* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from
- a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future.
* 'mercurial.hg.updatetotally' is now more thorough about checking its
- 'updatecheck' keyword argument. Previously invalid values would have used
the configured default updatecheck method, but now will raise ValueError.
* 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking
- up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.
25.3. commands

- bookmarks: actual fix for race condition deleting bookmark
- bookmarks: remove changectx() method from bmstore (API)
- branchmap: explicitly warm+write all subsets of the branchmap caches
- import: add debug messages when parsing data from patch header
- import: read X-Mercurial-Node email header to determine nodeid

- push: support config option to require revs be specified when running push
