sshpeer: set a blockedtag when starting ssh So that the data is readable.

revert: always display hunks reversed when reverting to parent When reverting to the parent of working directory, operation is "discard" so we want hunks to be presented in the same order as the diff (i.e. "reversed"). So we do not query the experimental.revertalternateinteractivemode option in this case and always set "reversehunks" to True.

fileset: add a 'status(...)' predicate to control evaluation context Same as 'revs', this predicate does not select files but switches the evaluation context. This allow to match file according arbitrary status call. We can now express the same query as 'hg status'. The API (two 'revsingle' class) have been picked instead of a single 'revs' revset for multiple reasons: * it is less confusing to express * it allow to express more query (eg: backward status, cross branch status)

fileset: allow to specify a basectx for status This will be used for a predicates that defines the status range of a match.

fileset: add revs(revs, fileset) to evaluate set in working directory Unlike other functions, "revs()" does not select files but switches the evaluation context. This allow to match file with property in another revision that the one currently evaluated. This changeset is based on work from Yuya Nishihara.

fileset: add function to switch revision where fileset will be evaluated If the subset isn't filtered yet, i.e. if fullmatchctx, the new subset is recalculated from scratch. Otherwise, it is narrowed by the existing subset.

fileset: extract function that builds status tuple only if necessary This function will be used to recalculate status when mctx.ctx is switched.

fileset: build initial subset in fullmatchctx class

fileset: extract function that builds initial subset from ctx or status This function will be used to recalculate subset when mctx.ctx is switched.

fileset: add class to host special handling of initial subset Future patches will add a function to switch mctx.ctx object so that we can forcibly evaluate a fileset expression in a specified revision. For example, new "revs()" function will be used to match predicate agains another revision $ hg revert 'set:revs(42, added())' fullmatchctx class is similar to revset.fullreposet. It will allow us to recalculate the subset only if it is not filtered yet.

patchbomb: add config knob to generate flags by template (issue5354) This can be used to flag patches by branch or topic automatically. Flags optionally given by --flag option are exported as {flags} template keyword, so you can add --flag V2.

patchbomb: pass around ui and revs that are needed for flag template See the next patch for why.

patchbomb: build patch texts by _getpatchmsgs() Now _getpatchmsgs() knows revision numbers, which allows us to generate flags by applying a template to changectx objects.

patchbomb: drop internal option for pbranch extension (API) I want to move _getpatches() to _getpatchmsgs() to make sure each patch text is tied with the corresponding revision number. This helps adding templater support. IIRC, the pbranch extension doesn't work with the recent Mercurial versions, so the removal of this option wouldn't hurt.

patchbomb: factor out function that builds a prefix string to patch subject I'll add templating support.

formatter: add argument to change output file of non-plain formatter This allows us to build data not written to the console. That would be doable by ui.pushbuffer()/popbuffer(), but changing the file object seems cleaner.

schemes: move re construction to module-level and python3-ify This makes the schemes extension load correctly in Python 3.

dispatch: cope with sys.version being unicode on Python 3

dispatch: allow testedwith to be bytes or str

ui: fix ui.traceback on Python 3

ui: fix opts labeling on ui.warn et al for Python 3 This is a step towards fixing extension load warnings on Python 3. Note that I suspect there are still some bugs in this area and that things like color won't work, but the code at least executes and prints text to the console correctly now.

config: add sanity assert that files are opened as binary This helps with some debugging in Python 3, and shouldn't hurt anything in Python 2. The unusual construction using getattr is done so that StringIO/BytesIO instances can be used as well as real files.

update: for "noconflict" updates, print "conflicting changes" on conflict With experimental.updatecheck=noconflict, if the update is aborted because of conlicts, "uncommitted changes" is not quite accurate. Let's use "conflicting changes" instead. Also fix the hint to recomment --clean, not --merge, since that's what we do for other failed updates.

tests: fix test-update-branches to remove non-conflicting file I was clearly very sloppy when I wrote the test case for experimental.updatecheck=noconflict. The test case that checks that one can move between commits with a removed file was deleting a file that was modified between the source and target commits, which resulted in a "change/delete" conflict. Since that is a conlict, the update correctly failed. Let's fix the test by removing a file that is not modified between the two commits.

branches: populate all template keywords in formatter This is a usage example of fm.context().

formatter: add support for changeset templating Some formatter-based commands provide fields that are identical to the ones defined in templatekw, but we had to specify them manually to support all changeset-based template keywords. This patch adds fm.context() that populates all templatekw. These keywords are available only in template output, so we still need to set important keywords via fm.data() if they should be available in e.g. JSON output. Currently fm.context() takes only 'ctx' argument. It will eventually be extended to take 'fctx' to support file-based keywords (e.g. {path}) seen in hgweb.

templatekw: move defaulttmpl constant from changeset_templater These templates are used when rendering inner lists of some template keywords, so it makes sense to define them in templatekw. This allows us to reuse them to create a templateformatter knowing changectx.

formatter: drop filters argument from maketemplater() It's unused now. I want to keep the high-level API simple.

templater: port formatnode filter from changeset_templater This slightly reduces the difference between changeset_templater and formatter, and helps extending formatter to support changeset templating. New formatnode() is not a template filter, but a function since a filter cannot access to ui. And it's marked as DEPRECATED since I think it exists only for compatibility reasons.

update: allow setting default update check to "noconflict" The new value allows update (linear or not) as long as they don't result in file merges. I'm hoping that this value can some day become the default.

update: add experimental config for default way of handling dirty wdir This allows the user to set e.g. experimental.updatecheck=abort to abort update if the working directory is dirty, but still be able to override the behavior with e.g. --merge when needed. I considered adding a --mergelinear option to get back the old behavior even when experimental.updatecheck=abort is set, but I couldn't see why anyone would prefer that over --merge. The default is read in hg.updatetotally(), which means it also applies to "hg pull -u" and "hg unbundle -u".

update: accept --merge to allow merging across topo branches (issue5125)

merge: combine the "merge" cases in docstring table

merge: combine "dirty" cases in docstring table

merge: clarify non-linear default updates in docstring table Non-linear updates won't happen by default, regardless of -c/-C.

merge: combine the two "can't happen" cases in docstring table

merge: move "incompatible options" case first in docstring table

merge: make "linear" an input in docstring table Instead of having two ouputs, it seem simpler to have an addition input. This will allow further simplification.

merge: drop redundant column in docstring table The "same" and "cross" columns now have the same values, so let's combine them into "non-linear".

merge: drop obsolete non-linear cases from docstring table Since 6b1fc09c699a (update: change default destination to tipmost descendant (issue4673) (BC), 2016-02-02), non-linear updates can no longer happen if the user doesn't specify a destination, so we can drop these case from the table in the docstring of merge.update().

revert: move code dealing with deletions closer together

ui: fix configlist on Python 3 Since we're working on bytestrings, we have to use [offset:offset+1] to get consistent behavior on Python 2 and 3. I've only tested the _parse_plain closure, not the _parse_quote one, but I have no real reason to expect the latter to be broken since the fixes were fairly mechanical.

config: pass some optional args as keywords This makes it a little more obvious that self.read is being passed as include, which took me a moment to figure out.

config: load included config files in binary mode I guess we've been getting lucky that this works in Python 2. This fixes loading included config files in Python 3 (it used to fail on the "somebody set up us the BOM" check.)

manifest: remove _repo from manifestctx objects We were storing the repo on the manifestctx objects so that they could access the manifestlog via repo.manifestlog, which would refresh the structure if it became out of date. This caused probems however when we want to have multiple manifest logs in memory at once, like when transitioning to tree manifest from flat manifests, since a tree manifest would try to access sub-trees via repo.manifestlog[node], which was the flat manifest. The solution is to just not store the repo, and instead store the manifestlog that created this context. This removes the invalidation when the in memory manifestlog becomes out of date, but people should probably not be keeping ctx's around that long anyway.

phases: remove experimental.nativephaseskillswitch The native code has been used for a long time. Therefore drop the experimental config option.

manifest: allow specifying the revlog filename Previously we had hardcoded the manifest filename to be 00manifest.i. In our external treemanifest extension, we want to allow writing a treemanifest side by side with a flat manifest, so we need to be able to store the root revisions at a different location (in our extension we use 00manifesttree.i). This patches moves the revlog name to a parameter so we can adjust it.

py3: drop unrequired code from __init__.py Once we are using pycompat.open(), we don't need this hack to convert the second argument to unicodes. So removing this.
