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)

largefiles: teach log to handle patterns Adding the standin to the patterns list was (possibly) harmless before, but was wrong, because the pattern list was already updated above that code. Now that patterns are handled, it was actually harmful. For example, in this test: $ hg log -G glob:**another* the adjusted pattern list would have been: ['glob:**another*', '.hglf/.', 'glob:.hglf/**another*'] which causes every largefile in the root to be matched. I'm not sure why 'glob:a*' picks up the rename of a -> b commit in test-log.t, but a simple 'a' doesn't. But it doesn't appear to be caused by the largefiles extension.

check-code: allow disabling msys path check

revset: extend fullreposet to make "null" revision magically appears in set As per fullreposet.__and__, it can omit the range check of rev. Therefore, "null" revision is accepted automagically. It seems this can fix many query results involving null symbol. Originally, the simplest "(null)" query did fail if there were hidden revisions. Tests are randomly chosen. fullreposet mimics the behavior of localrepo, where "null" revision is not listed but contained.

revset: duplicate spanset.__contains__ to fullreposet for modification 1d7a2771aa36 says we should avoid function calls in __contains__, so super(fullreposet, self).__contains__(rev) is not an option. Actually the super call doubled the benchmark result of trivial query: revisions: 0) 678f53865c68 (tip when I wrote this patch) 1) rev == node.nullrev or super(fullreposet, self).__contains__(rev) revset #0: tip:0 0) wall 0.008441 comb 0.010000 user 0.010000 sys 0.000000 (best of 282) 1) wall 0.016152 comb 0.010000 user 0.010000 sys 0.000000 (best of 146)

revset: have all() filter out null revision I'm not sure if "all()" should filter out "null", but "all()" is stated as 'the same as "0:tip"' (except that it doesn't reorder the subset, I think.) This patch is intended to avoid exposing a fullreposet to graphmod.dagwalker(), which would result in strange drawing in future version: | o changeset: 0:f8035bb17114 | user: test | date: Thu Jan 01 00:00:00 1970 +0000 | summary: add a caused by: parents = sorted(set([p.rev() for p in ctx.parents() if p.rev() in revs])) We cannot add "and p.rev() != nullrev" here because revs may actually include "null" revision.

revset: drop unnecessary calls of getall() with empty argument If x is None, getall(repo, subset, x) == subset.

graphlog: do not bypass commands.log so that -fr works Since 8b4b9ee6001a, opts dict can be modified in commands.log() before calling cmdutil.graphlog().

histedit: add a config allowing changing histedit rule line length limit Since many users are using terminals wider than 80 chars there should be an option to have longer lines in histedit editor. Even if the summary line is shorter than 80 chars after adding action line prefixes (like "pick 7c2fd3b9020c") it doesn't fit there anymore. Setting it to for example 110 would be a nice option to have.

dirstate: make sure rootdir ends with directory separator (issue4557) ntpath.join() of Python 2.7.9 does not work as expected if root is a UNC path to top of share. This patch doesn't take care of os.altsep, '/' on Windows, because root should be normalized by realpath().

i18n-de: fix a typo in the german translation

histedit: fix style of new error message - lowercase - no punctuation - brief - short node

Makefile: allow setting HGTESTFLAGS in shell environment for TESTFLAGS I keep wanting to run 'make tests', but I forget to set TESTFLAGS='-j 16' or whatever is reasonable for my machine. This lets me just set it once in my shell settings and forget it.

Makefile: introduce testpy-% target for testing with a specifc Python This makes it easy to do 'make testpy-2.4.6 TESTFLAGS="-j 16"' and the Makefile will build Python if needed and then run tests (with -j 16) with the resulting Python. You can set the environment variable HGPYTHONS to a nice location on your machine to cache the Python builds globally. If that's not set, it builds them inside build/pythons.

extdiff: expand tildes and variables in paths to user-supplied diff programs
