statichttprepo: update profile of __call__ in mock vfs object New code paths could fail because the old statichttprepo profile couldn't handle the usual parameters. Instead, reuse a more generic profile also used in readonlyvfs.

tests: avoid git diffstat singular/plural output difference 'git diff --stat' output changed with regard to the amount of changes/insertions/deletions shown. In older git versions (1.7.7.6), output was shown as: 2 files changed, 2 insertions(+), 1 deletions(-) In newer versions, output is shown as: 2 files changed, 2 insertions(+), 1 deletion(-) This patch uses a regex to handle both cases.

subrepo: add revert support without backup for git subrepos Previously, git subrepos did not support reverting. This change adds basic support for reverting when '--no-backup' is specified. A warning is given (and the current state is kept) when a revert is done without the '--no-backup' flag.

match: make 'always' and 'exact' functions, not classes There is no reason for classes 'always' and 'exact' not to be just functions that return instances the plain 'match' class.

share: implement shared bookmark functionality This does not cause any behavioral change unless a 'bookmarks.shared' marker file exists. A future change will add UI to create this file when a repository is shared.

debugindex: respect --debug flag to show full nodeids

localrepo.clone: add a way to override server preferuncompressed Without this patch, if the server sets preferuncompressed, there's no way for clients to override that and force a non-streaming clone. With this patch, we extend the meaning of --pull to also override preferuncompressed and force a non-streaming clone.

hg.clone: set 'stream' depending on whether --pull was requested or not In an upcoming patch we'll differentiate between the two in localrepo.

merge: perform case-collision checking on final set of actions When there are multiple common ancestors, we should check for case collisions only on the resulting actions after bid merge has run. To do this, move the code until after bid merge. Move it past _resolvetrivial() too, since that might update actions. If the remote changed a file and then reverted the change, while the local side deleted the file and created a new file with a name that case-folds like the old file, we should fail before this patch but not after. Although the changes to the actions caused by _forgetremoved() should have no effect on case collisions, move it after that, too, so the next person reading the code won't have to think about it. Moving it past these blocks of code takes it to the end of calculateupdates(), so let's even move it outside of the method, so we also check collisions in actions produced by extensions overriding the method.

spelling: fixes from proofreading of spell checker issues

tests: allow more flexibility in git diffstat output The output of 'git diff --stat' changed in git 1.7.10 and 1.7.11. To ensure the tests work with earlier versions of git as well, the output is now wrapped with a whitespace regex.

merge: move cd/dc prompts after largefiles prompts By moving the cd/dc prompts out of calculateupdates(), we let largefiles' overridecalculateupdates() so the unresolved values (i.e. 'cd' or 'dc' rather than 'g', 'r', 'a' and missing). This allows overridecalculateupdates() to ask the user whether to keep the normal file or the largefile before the user gets the cd/dc prompt. Whichever answer the user gives, we make overridecalculateupdates() replace 'cd' or 'dc' action, saving the user one annoying (and less clear) question.

addremove: automatically process a subrepository's subrepos Since addremove on the top of a directory tree will recursively handle sub directories, it should be the same with deep subrepos, once the user has explicitly asked to process a subrepo. This really only has an effect when a path that is a subrepo (or is in a subrepo) is given, since -S causes all subrepos to be processed already. An addremove without a path that crosses into a subrepo, will still not enter any subrepos, per backward compatibility rules.

addremove: support addremove with explicit paths in subrepos Git and svn subrepos are currently not supported.

addremove: add support for the -S flag Git and svn subrepos are currently not supported. It doesn't look like git or svn have these commands natively, so that's an area for a git or svn expert.

commit: propagate --addremove to subrepos if -S is specified (issue3759) The recursive addremove operation occurs completely before the first subrepo is committed. Only hg subrepos support the addremove operation at the moment- svn and git subrepos will warn and abort the commit.

subrepo: store the ui object in the base class This will be used in the next patch to print a warning from the base class. It seems better than having to explicitly pass it to a new method, since a lot of existing methods also require it.

commit: abort if --addremove is specified, but fails This will be required when subrepo support is added, in order to ensure consistent commits when a subrepo flavor doesn't support addremove.

addremove: warn when addremove fails to operate on a named path It looks like a bad path is the only mode of failure for addremove. This warning is probably useful for the standalone command, but more important for 'commit -A'. That command doesn't currently abort if the addremove fails, but it will be made to do so prior to adding subrepo support, since not all subrepos will support addremove. We could just abort here, but it looks like addremove has always silently ignored bad paths, except for the exit code.

scmutil: pass a matcher to scmutil.addremove() instead of a list of patterns This will make it easier to support subrepository operations.

tests: fix a typo in test-walkrepos.py

merge: extract _resolvetrivial() function We would eventually like to move the resolution of modify/delete and delete/modify conflicts to the resolve phase. However, we don't want to move the checks for identical content that were added in 902554884335 (merge: before cd/dc prompt, check that changed side really changed, 2014-12-01). Let's instead move these out to a new _resolvetrivial() function that processes the actions from manifestmerge() and replaces any false cd/dc conflicts. The function will also provide a natural place for us to later add code for resolving false 'm' conflicts.

largefiles: start by finding files of interest Instead of iterating over 'g' action, first find the set of all files that are largefiles in p1. Then iterate over these files. This prepares for considering actions other than 'g'.

largefiles: rewrite merge code using dictionary with entry per file In overridecalculateupdates(), we currently only deal with conflicts that result in a 'g' action for either the largefile or a standin. We will soon want to deal cases with 'cd' and 'dc' actions here. It will be easier to reason about such cases if we rewrite it using a dict from filename to action. A side-effect of this change is that the output can only have one action per file (which should be a good change). Before this change, when one of the tests in test-issue3084 received this input (the 'a' in the input was a result of 'cd' conflict resolved in favor of the modified file): 'g': [('.hglf/f', ('',), 'remote created')], 'a': [('f', None, 'prompt keep')], and the user chose to keep the local largefile, it produced this output: 'g': [('.hglf/f', ('',), 'remote created')], 'r': [('f', None, 'replaced by standin')], 'a': [('f', None, 'prompt keep')], Although 'a' actions are processed after 'r' actions by recordupdates(), it still worked because 'a' actions have no effect on merges (only on updates). After this change, the output is: 'g': [('.hglf/f', ('',), 'remote created')], 'r': [('f', None, 'replaced by standin')], Similarly, there are several tests in test-largefiles-update that get inputs like: 'a': [('.hglf/large2', None, 'prompt keep')], 'g': [('large2', ('',), 'remote created')], and when the user chooses to keep the local largefile, they produce this output: 'a': [('.hglf/large2', None, 'prompt keep'), ('.hglf/large2', None, 'keep standin')], 'lfmr': [('large2', None, 'forget non-standin largefile')], In this case, it was not a merge but an update, so the 'a' action does have an effect. However, since dirstate.add() is idempotent, it still has no obserable effect. After this change, the output is: 'a': [('.hglf/large2', None, 'keep standin')], 'lfmr': [('large2', None, 'forget non-standin largefile')],

largefiles: put same 'action' object back in 'newglist' The items we put in 'newglist' are always the same as what we found in actions['g'], so let's just put the same item into the list instead of creating a new one.

largefiles: don't unnecessarily sort merge action lists The action lists returned from calculateupdates() (in merge.py) are not required to be sorted. In fact, since they result from iteration over the unordered manifest, they are unlikely to be sorted. Moreover, some of the lists are appended to after they are returned from manifestmerge(). The lists are instead sorted in applyupdates(). Therefore, let's not sort the lists generated in largefiles' overridecalculateupdates().

merge: don't treat 'diverge' and 'renamedelete' like actions See earlier patch for motivation.

merge: move dr/rd warning messages out of applyupdates() As preparation for making 'dr' and 'rd' actions no longer actions, move the reporting from applyupdates() to its caller update(). This way we won't have to pass additonal arguments to applyupdates() when they are no longer actions. Also, the warnings are equally unrelated to applyupdates() as they are to recordupdates(), as they don't result in any changes to either the working copy or the dirstate. See earlier patch for additional motivation.

merge: don't report progress for dr/rd actions It is easier to reason about certain algorithms in terms of a file->action mapping than the current action->list-of-files. Bid merge is already written this way (but with a list of actions per file), and largefiles' overridecalculateupdates() will also benefit. However, that requires us to have at most one action per file. That requirement is currently violated by 'dr' (divergent rename) and 'rd' (rename and delete) actions, which can exist for the same file as some other action. These actions are only used for displaying warnings to the user; they don't change anything in the working copy or the dirstate. In this way, they are similar to the 'k' (keep) action. However, they are even less action-like than 'k' is: 'k' at least describes what to do with the file ("do nothing"), while 'dr' and 'rd' or only annotations for files for which there may exist other, "real" actions. As a first step towards separating these acitons out, stop including them in the progress output, just like we already exclude the 'k' action.

subrepo: add partial diff support for git subrepos So far, git subrepositories were silently ignored for diffs. This patch adds support for git subrepositories, with the remark that --include and --exclude are not supported. If --include or --exclude are used, the subrepo is ignored.
