color: consolidate cut-and-paste code This fixes a mild case of cut-and-paste code regarding failing to set terminal modes. This is evident in the win32 comment that is misplaced for the terminfo mode since cset ad6ad51cc0dd. Instead, we refactor this C&P into a small local function.

cmdutil.tryimportone: allow importing relative patches with --bypass

cmdutil.tryimportone: allow importing relative patches into the working dir This makes hg import --prefix dir/ (without bypass) work.

commands.import: accept a prefix option The --prefix option is meant to be relative to the root rather than the current working directory. This is for consistency with the rest of 'hg import' -- paths in patches are otherwise considered to be relative to the root. In upcoming patches we'll hook this option up to the patch functions. --exact with --prefix is currently disallowed because I can't really come up with sensible semantics for it, especially when only part of the patch is preserved.

test: make version based test-extensions failure more explanatory A buggy __version__ content (usually from setup.py's hg being unable to read the repo) can make this test fails in an obscure manner. We make the root of the failure more explicit.

subrepo: add status support for ignored and clean files in git subrepos

revlog: addgroup checks if incoming deltas add censored revs, sets flag bit A censored revision stored in a revlog should have the censored revlog index flag bit set. This implies we must know if a revision is censored before we add it to the revlog. When adding revisions from exchanged deltas, we would prefer to determine this flag without decoding every single full text. This change introduces a heuristic based on assumptions around the Mercurial delta format and filelog metadata. Since deltas which produce a censored revision must be full-replacement deltas, we can read the delta's first bytes to check the filelog metadata. Since "censored" is the alphabetically first filelog metadata key, censored filelog revisions have a well-known prefix we can look for. For more on the design and background of the censorship feature, see: http://mercurial.selenic.com/wiki/CensorPlan

patch.internalpatch: accept a prefix parameter

patch.patchbackend: accept a prefix parameter

repair: define explicit local variable, don't reuse a comprehension variable The node ID used in strip bundle names is currently taken as the last iterated value in a list comprehension found much earlier in the function. This change makes the node selection more explicit at the cost of redundancy.

commands.paths: use ui.paths to show paths We now have an API for representing a collection of paths. Use it.

ui: represent paths as classes Many have long wanted for paths to have expanded functionality and flexibility. In order to make that transition possible, we need to start representing paths as something more than simple strings. This patch introduces two classes: 1) "path" for representing a single path instance 2) "paths" for representing a collection of "paths" Since we don't like patches that introduce new code without any consumers, we convert ui.expandpath() to use the new APIs internally. Upcoming patches will start exposing "path" instances to consumers that currently interface with string paths. The new "paths" attribute of ui is populated from config data the first time it is accessed. Since it isn't updated when the configs are modified, this could lead to some inaccurate caching behavior. It shouldn't be an issue, as paths information is typically not accessed until command dispatch, which occurs after the repository config and extensions have been loaded. Time will tell if we need to refresh paths information when the underlying config changes.

color: omit terminfo/win32 warning if non-interactive (issue4543) It's pretty annoying to be getting this warning when already the colour extension has no hope of working. If there isn't a human on the other end to to see the colours, there probably isn't a human either who cares about this warning. More likely, some script somewhere is gonna get confused with the warning output. Of course, if we still want to see the warning for some reason, we can always set --config ui.interactive=True.

incoming: hide help about use of --bundle option by default Pulling from incoming bundle can cause trouble such as missing phase movement, bookmarks and largefiles transfer. Average user won't need this option.

patch.applydiff: accept a prefix parameter This is preparation for upcoming patches that will add support for applying a patch within a subdirectory.

patch._applydiff: accept a prefix parameter This is preparation for upcoming patches that will add support for applying a patch within a subdirectory. We normalize the prefix here because this is the main driver -- all code to apply patches is expected to go through here.

patch.makepatchmeta: accept a prefix parameter This is preparation for upcoming patches that will add support for applying a patch within a subdirectory.

patch.pathtransform: add a prefix parameter This is preparation for upcoming patches that will add support for applying a patch within a subdirectory. The prefix is applied after path components are stripped.

patch.pathtransform: add doctests In upcoming patches we're going to make this function more complex, so add some unit tests for it.

patch: rename pathstrip to pathtransform In upcoming patches we'll not just strip path components but also add new ones.

templatekw: forward _hybrid.get to raw values so that get(extras, key) works ef78450c8df6 implies that the primary goal is to allow "{get(extras, key)}", but it didn't work. I'm not sure if _hybrid should forward all unknown attributes to values, so only "get" is forwarded for now.

templater: implement _hybrid.__contains__ so that ifcontains can accept dict d8fb835376d1 is fine for "{revset()}", but "i.values()[0]" does not work if each item has more than one values such as "{bookmarks}". This fixes the problem by using list.__contains__ or dict.__contains__ appropriately.

templatekw: keep raw list or dict in _hybrid object This will allow us to handle bookmarks, extras and copies properly in "ifcontains()" and "get()".

templatekw: give name to lambda that constructs variables map of templater The constructed list is useless for "ifcontains()" and "get()". Instead, makemap() and raw dict will be passed to _hybrid object.

templatekw: convert list of key/value pairs to sortdict These sortdict objects will be passed to _hybrid later, which will allow us to handle them by "ifcontains()" and "get()" as expected.

sortdict: have update() accept either dict or iterable of key/value pairs Future patches will make the templater store a sorted dict in the _hybrid object. sortdict should be constructed from a sorted list.

record: allow editing new files (issue4304) While using the record extension to select changes, the user couldn't see the content of newly added files and had to select/reject them based on filename. The test is changed accordingly in two places.

localrepo: back out changeset b08af8f0ac01 Running the tags function filtered will lead to different results with different filter levels. This seems too dangerous to be done blindly as b08af8f0ac01 did.

test-shelve: be more lenient about whitespace (issue4124) When running on a slower systems (eg. MIPS buildd), the age of the shelf can be 10 seconds or more, resulting in the output alignment changing and thus a test failure. This patch makes the spacing be matched more leniently.

histedit: use better meta-variable names than VALUE in help text Before this change hg help histedit would use the default variable label: --commands VALUE ... -r --rev VALUE [+] With this change the text will be in the usual help text style and a bit more explanatory: --commands FILE ... -r --rev REV [+]

histedit: tweak --commands help text The rest of help messages for command arguments are simple phrases without any ending punctuation, so having this text be a complete sentence didn't really fit.

largefiles: report the source of copied/moved largefiles in status -C Previously, the source was silently skipped because the largefile was in the list of changed files, but the standin was in the copies dictionary. The source is only displayed if the changed file is a key in the copies dictionary.

test-commit-amend: add globs for Windows

lazymanifest: use a binary search to do an insertion This makes insertions log(n) plus some memmove() overhead, rather than doing an append followed by an n*log(n) sort. There's probably a lot of performance to be gained by adding a batch-add method, which could be smarter about the memmove()s performed. Includes a couple of extra tests that should help prevent bugs. Thanks to Martin for some significant pre-mail cleanup of this change.

context: don't sort manifest entries The manifest iterator is now pre-sorted, so we can skip this check.

manifest: use custom C implementation of lazymanifest This version is actually lazy, unlike the pure-python version. The latter could stand to be optimized if anyone actually wants to use it seriously. I put no work into it. Before any of my related changes on mozilla-central: perfmanifest tip ! wall 0.268805 comb 0.260000 user 0.260000 sys 0.000000 (best of 37) perftags ! result: 162 ! wall 0.007099 comb 0.000000 user 0.000000 sys 0.000000 (best of 401) perfstatus ! wall 0.415680 comb 0.420000 user 0.260000 sys 0.160000 (best of 24) hgperf export tip ! wall 0.142118 comb 0.140000 user 0.140000 sys 0.000000 (best of 67) after all of my changes on mozilla-central: ./hg: perfmanifest tip ! wall 0.232640 comb 0.230000 user 0.220000 sys 0.010000 (best of 43) perftags ! result: 162 ! wall 0.007057 comb 0.010000 user 0.000000 sys 0.010000 (best of 395) perfstatus ! wall 0.415503 comb 0.420000 user 0.280000 sys 0.140000 (best of 24) hgperf export tip ! wall 0.025096 comb 0.030000 user 0.030000 sys 0.000000 (best of 102) so it's no real change in performance on perf{manifest,tags,status}, but is a huge win on 'hgperf export tip'. There's a little performance work that could still be done here: fastdelta() could be done significantly more intelligently by using the internal state of the lazymanifest type in C, but that seems like good future work.

manifest: split manifestdict into high-level and low-level logic The low-level logic type (_lazymanifest) matches the behavior of the C implementation introduced in a5f1bccd. A future patch will use that when available.

manifest: do parsing inside manifestdict contstructor This shape to the code will make using a C implementation of the manifest storage easier.

manifest: move parsing functions up in file These functions are about to change signature and be hidden inside the manifestdict constructor. Doing the code motion now as an isolated change to make things easier to review.

dispatch: offer suggestions of similar-named commands When suggestions are available, we show those suggestions instead of showing some help output.

dispatch: offer near-edit-distance suggestions for {file,rev}set functions Before this patch, when I have a brain fart and type `hg log -r 'add(foo)'`, hg exits and just says add isn't a function, leading me to the help page for revset to figure out how to spell the function. With this patch, it suggests 'adds' as a function I might have meant.

test-revset: add tests for missing function output An upcoming change will slightly alter behavior here. Adding the test now so the output change stands out in the later changeset.

revset: use UnknownIdentifier where appropriate

fileset: use UnknownIdentifier where appropriate

error: add a new UnknownIdentifier error type This will be used by the revset and fileset code to communicate more specific errors to higher levels so that we might be able to offer suggestions about what function might have been similar.

log: display closing-branch nodes as "_" (BC) In plain `hg log` there is no indication that a commit closes a branch. You can use hg log --debug, but this is too verbose. A simple idea copied from thg and other graphical viewers is to display the node for a closing-branch commit as a horizontal line. I think this technically is a BC if we consider the graphlog to be part of the stdout API, but I really can't imagine who the hell is parsing the graphlog to determine information about commits.

manifest: move pure parsing code out of pure This lets us transition more smoothly.

manifest.c: new extension code to lazily parse manifests This lets us iterate manifests in order, but do a _lot_ less work in the common case when we only care about a few manifest entries. Many thanks to Mike Edgar for reviewing this in advance of it going out to the list, which caught many things I missed. This version of the patch includes C89 fixes from Sean Farley and many correctness/efficiency cleanups from Martin von Zweigbergk. Thanks to both!

workingctx: use normal dirs() instead of dirstate.dirs() The workingctx class was using dirstate.dirs() as it's implementation. The sparse extension maintains a pruned down version of the dirstate, so this resulted in the workingctx reporting an incorrect listing of directories during merge calculations (it was detecting directory renames when it shouldn't have). The fix is to use the default implementation, which uses workingctx._manifest, which unions the manifest with the dirstate to produce the correct overall picture. This also produces more accurate output since it will no longer return directories that have been entirely deleted in the dirstate. Tests will be added to the sparse extension to detect regressions for this.

subrepo: only fetch unknown files from git when explicitly requested

subrepo: always return scmutil.status() from gitsubrepo.status() This was accidentally left out of c95db3208a33.

subrepo: explicitly request clean and unknown files in status for git's add No behavior changes here since gitsubrepo.status() doesn't currently populate clean, and ignores whether unknown files were actually requested. But this is in line with other calls to status, and should avoid future surprises.

largefiles: handle logging from outside the repo It's probably possible to refactor so that the 'if m._cwd' check isn't necessary, but the False case is the typical case (i.e. run from the root of the repo), and simpler to read. An exact path to a largefile from outside the repo was previously ignored. match.rel('.hglf') will handle figuring out both the correct '../' length to the standin directory if inside the repo, or path/to/repo from outside, at the cost of a pconvert() to keep the patterns using '/' on Windows.

largefiles: don't prefix standin patterns with '.hglf' when logging When logging '.hglf/foo', the pattern list was being transformed from ['.hglf/foo'] into ['.hglf/foo', '.hglf/.hglf/foo']. Aside from the pathological case of somebody getting a directory named '.hglf' created inside the standing directory, the old code shouldn't have had any bad effects. (amended by mpm to sort patterns for test stability and not upset check-code)
