dirstate: add filecache support

scmutil: add join method to opener to construct path relative to base Useful when we only have the opener without the base path used when it was constructed.

filecache: refactor path join logic to a function New users of filecache use different names for the function used to compute the runtime path of the cached file. Users should subclass filecache and provide their own version of this function to call the appropriate join function on 'obj' (an instance of the class that its member function was decorated).

subrepo: fix for merge inconsistencies Merging ancestors with children is allowed if they are on different named branches. This did not work for subrepo merges before. To fix this inconsistency, the mergefunc() will now use the simple update path only if both versions are on the same named branch. If not, they get merged into a new changeset, just as if you did the merge from the subrepo's root directly.

bundlerepo: bundle repos should be non-publishing (issue3266) Bundle repo contains both the bundle content and the content of the repository used as a base. This create bugs with phases exchange because the "remote" repository claim to contains changeset it does not. The easiest way to fix this bug is to ensure a bundle repo as non publishing. This way changeset will be seen in the same phase than locally. This patch does not alter in which phase bundle revision are seen. For now they are seen as if an old client had add them on the remote: They inherit their phase from parent whatever the parent is. This is to be fixed in a later patch

bookmarks: restore python 2.4 compatibility Remove py25 'try except finally' clause.

bugzilla: stop XMLRPC requests from requesting gzipped responses Python 2.7 introduced support for gzip encoding in xmlrpclib.Transport. We do our own handling of responses, and don't currently support gzip encoding. So to run successfully under Python 2.7 with a web server configured to gzip encode, stop XMLRPC requests from announcing gzip encoding support.

setup: handle output from Apple's Xcode 4.3 better (issue3277) Apparently, it prints nothing at all if the user installed only the command-line tools. In that case, don't try to parse the empty output -- just assume they have Xcode >= 4.

graphlog: apply file filters --patch/--stat output When passing --patch/--stat, file filters have to be applied to generate the correct diff or stat output: - Without --follow, the static match object can be reused - With --follow, the files displayed at revision X are the ancestors of selected files at parent revision. To do this, we reproduce the ancestry calculations done by --follow, lazily. test-glog.t changes show that --patch output is not satisfying because renames are reported as copies. This can probably be fixed by: - Without --follow: compute files to display, look for renames sources and extend the matcher to include them. - With --follow: detect .path() transitions between parent/child filectx, filter them using the linked changectx .removed() field and extend fcache with them.

context: add followfirst arg to filectx and workingfilectx When _followfirst() revset was introduced it seemed to be the sole user of such an argument, so filectx.ancestors() was duplicated and modified instead. It now appears this argument could be used when computing the set of files to be considered when --patch or --stat are passed along with --follow FILE.

graphlog: fix --removed "hg log --removed FILE" does not return changesets where FILE was removed, but ones where FILE was changed and possibly removed. The flag is really here to disable walkchangerevs() fast path, which cannot see file removals by scanning filelogs.

test-glog: rewrite more tests using testlog() function

match: consider filesets as "anypats" Matt suggested this on IRC, I do not think the choice is obvious, but this one makes things simpler because while filesets are turned into a list of files into the match objects, it would more be difficult to tell invalid files passed in pats from those expanded from filesets.

graphlog: evaluate FILE/-I/-X filesets on the working dir This subtlety is not documented yet but: - pats/--include/--exclude filesets are evaluated against the working directory - --rev filesets are reevaluated against every revisions

log: restore cache used by --copies The {filelog -> linkrev -> copyfrom} cache was refactored and broken by: changeset: 10060:f780b1098efc user: Patrick Mezard <pmezard@gmail.com> date: Sun Dec 13 18:06:24 2009 +0100 summary: templatekw: change {file_copies} behaviour, add {file_copies_switch} With --copies, this cache is accessed for every touched file of every revision. Unfortunately it is recreated for every revision, which means filelogs are parsed again. This patch makes the cache global again for all revisions. A couple of indicative timings of "hg log --copies", before and after: hg: 44s / 5s mozilla --limit 10000: 3m51s / 2m32s mozilla: 23m46s / 12m23s I do not know any good tool to trace memory consumption of these runs for comparisons. Watching the full mozilla run in top, the process did not seem to misbehave.

graphlog: implement --follow-first log --graph --follow-first FILE cannot be compared with the regular version because it never worked: --follow-first is not taken in account in walkchangerevs() fast path and is explicitely bypassed in FILE case in walkchangerevs() nested iterate() function.

graphlog: implement --follow with file arguments

test-glog: test multiple --prune values

graphlog: restore FILE glob expansion on Windows On platforms not supporting shell expansion, scmutil.match() performs glob expansion on 'pats' arguments. But _matchfiles() revset calls match.match() directly, bypassing this behaviour. To avoid duplicating scmutil.match(), a secondary scmutil.matchandpats() is introduced returning both the match object and the expanded inputs. Note the expanded pats are also needed in the fast path, and will be used by --follow code path.

glog: restore multiple --rev test lost in rebasing

copies: remove checkdirs options This removes the undocumented merge.followdirs option, which has always been true.

log: fix --follow FILE ancestry calculation Currently, --follow FILE looks for a FILE filelog, scans it and collects linkrevs and renames, then filters them. The problem is the filelog scan does not start at FILE filenode in parent revision but at the last filelog revision. So: - Files not in the parent revision can be followed, the starting node is unexpected - Files in the parent revision can be followed from an incorrect starting node. This patch makes log --follow FILE fail if FILE is not in parent revision, and computes ancestors of the parent revision FILE filenode.

test-glog: extend a test before fixing --follow issues The changes add a lot of noise to the test output, I prefer to separate it from the changes which are to be introduced by --follow fixes.

graft: use proper revisions for copy detection (issue3265)

convert: fix typos in error messages

graphlog: paths/-I/-X handling requires a new revset The filtering logic of match objects cannot be reproduced with the existing revsets as it operates at changeset files level. A changeset touching "a" and "b" is matched by "-I a -X b" but not by "file(a) and not file(b)". To solve this, a new internal "_matchfiles(...)" revset is introduced. It works like "file(x)" but accepts more than one argument and its arguments are prefixed with "p:", "i:" and "x:" to be used as patterns, include patterns or exclude patterns respectively. The _matchfiles revset is kept private for now: - There are probably smarter ways to pass the arguments in a user-friendly way - A "rev:" argument is likely appear at some point to emulate log command behaviour with regard to filesets: they are evaluated for the parent revision and applied everywhere instead of being reevaluated for each revision.

graphlog: imitate log slowpath when inputs are explicit files

test-check-code-hg: fix xargs exit status on OSX When xargs subcommand invocation fails in a normal way, GNU xargs returns 123 and BSD one returns 1.

largefiles: respect store.createmode and avoid extra file copy Before, a tempfile was used to create a temp file was created with 600 permissions and the uploaded data was written into it. This file was then *copied* to .hg/largefiles/<hash>. We now simply use atomictempfile to write the data to a temp file with the right permissions and then rename that into place.

largefiles: respect store.createmode in basestore.get This replaces another use of tempfile with atomictempfile. The problem with tempfile is that it creates files with 600 permissions instead of respecting repo.store.createmode.

largefiles: use repo.store.createmode for new files in .hg/largefiles Before, the mode was copied from the file in the working copy. This is inconsistent with how Mercurial normally creates files inside the .hg folder. This can lead to a situation where you can read the files under .hg/store but not under .hg/largefiles and so a clone will fail if it needs to access a largefile.

graphlog: explicitely join multivalue parameters This will let use override the "join" value (and/or) depending on the option considered. The option revset arity is now deduced from the revset and the option value type, to simplify opt2revset definition.

test-glog.t: use printrevset extension to trace rewritten revsets Using "hg log -G --print-revset" prints the revset generated by graphlog and exits. This helps debugging and writing shorter tests. It has been suggested to handle these tests with doctests. I think the extension approach is better because: - It tests the actual parameter set passed to graphlog.revset(), not what we expect it to be. 'branch' and 'only-branch' are currently distinct options but nothing prevents fancyopts to grow a notion of option aliasing one day, where both options would be merged before reaching the command. - It can be used as debug output interleaved with real log calls. v2: - Use a test extension instead of a global deprecated new option

context: use 'changectx.dirs()' in 'walk()' for directory patterns this patch uses 'changectx.dirs()' instead of nested loop, to examine whether specified pattern is related to the context as a directory or not.
