bookmarks: clear active bookmark on non-linear update

convert: unescape Perforce-escaped special characters in filenames

convert: allow customizing git remote prefix Previously all git remotes were created as "remote/foo". This patch adds a configuration option for deciding what the prefix should be. This is useful if you want the bookmarks to be "origin/foo" like they are in git, or if you're integrating with the remotenames extension and don't want the local remote/foo bookmarks to overlap with the remote foo bookmarks.

help: rewrite template examples to not use shell escaping Though they work fine even on cmd.exe, these examples could lead to misguided understanding about the template syntax.

templater: unify "string" and "rawstring" "rawstring" was introduced by 5ab28a2e9962, but it's no longer necessary because c1975809a6b5 and fd5bc660c9f0 changed the way of processing string literals. This patch moves string decoding to the parsing phase as it was before: ('rawstring', s) -> ('string', s) ('string', s) -> ('string', s.decode('string-escape'))

templater: remove processing of "string" literals from tokenizer They are processed as "template" strings now.

templater: introduce one-pass parsing of nested template strings Instead of re-parsing quoted strings as templates, the tokenizer can delegate the parsing of nested template strings to the parser. It has two benefits: 1. syntax errors can be reported with absolute positions 2. nested template can use quotes just like shell: "{"{rev}"}" It doesn't sound nice that the tokenizer recurses into the parser. We could instead make the tokenize itself recursive, but it would be much more complicated because we would have to adjust binding strengths carefully and put dummy infix operators to concatenate template fragments. Now "string" token without r"" never appears. It will be removed by the next patch.

templater: check existence of closing brace of template string

templater: extract function that parses template string It will be called recursively to parse nested template strings.

templater: respect stop position while parsing template string It has no effect now because stop is len(tmpl).

hgweb: provide links to branches, tags and bookmarks by name (paper and coal) It's sometimes handy to, say, have a url always point to branch head, not just at the current branch head by node hash. Previously, this was only possible by manually editing url and replacing node hash with branch/tag/bookmark name. It wasn't very convenient, or easy - in case the name contained special characters that needed to be urlencoded. Let's have /branches, /tags and /bookmarks pages in paper and coal style provide links both to symbolic revisions and to node hashes. This feature was wished for in issue3594.

templates: introduce revescape filter for escaping symbolic revisions There needs to be a way to escape symbolic revisions containing forward slashes, but urlescape filter doesn't escape slashes at all (in fact, it is used in places where forward slashes must be preserved). The filter considers @ to be safe just for bookmarks like @ and @default to look good in urls.

hgweb: allow symbolic revisions with forward slashes in urls It's possible to have a branch/tag/bookmark with all kinds of special characters, such as {}/\!?. While not very conveniently, symbolic revisions with such characters work from command line if user correctly quotes the characters. These characters also work in hgweb, when they are properly encoded, with one exception: '/' (forward slash, urlencoded as '%2F'), which was getting decoded before hgweb could parse it as a part of PATH_INFO. Because of that, hgweb was seeing it as any other forward slash, that is, as just another url parts separator. For example, if user wanted to see the content of dir/file at bookmark 'feature/eggs', url could be: '/file/feature%2Feggs/dir/file'. But hgweb tried to find a revision 'feature' and get contents of 'eggs/dir/file'. To fix this, let's assume forward slashes are doubly-urlencoded (%252F), so CGI/WSGI server decodes it into %2F. Then we can decode %2F in the revision part of the url into an actual '/' character. Making hgweb produce such urls will be done in the next 2 patches.

convert: ignore case changes in vieworder for Perforce Perforce sometimes mixes the case resulting in files being ignored.

convert: if getting a file from Perforce fails try to get it one more time When converting a particularly large Perforce changelist (especially with some big files), it is very likely to run into an intermittent network issue (e.g. WSAECONNRESET or WSAETIMEDOUT) getting one of the files, which will result in the entire changelist converting being aborted. Which can be quite unfortunate since you might have waited hours getting all other files. To mitigate this let's attempt to get the file one more time, escalating original exception if that attempt fails.

shelve: keep old backups if timestamp can't decide exact order of them Before this patch, backups to be discarded are decided by steps below at 'hg unshelve' or so: 1. list '(st_mtime, filename)' tuples of each backups up 2. sort list of these tuples, and 3. discard backups other than 'maxbackups' ones at the end of list This doesn't work well in the case below: - "sort by name" order differs from actual backup-ing order, and - some of backups have same timestamp For example, 'test-shelve.t' satisfies the former condition: - 'default-01' < 'default-1' in "sort by name" order - 'default-1' < 'default-01' in actual backup-ing order Then, 'default-01' is discarded instead of 'default-1' unexpectedly, if they have same timestamp. This failure appears occasionally, because the most important condition "same timestamp" is timing critical. To avoid such unexpected discarding, this patch keeps old backups if timestamp can't decide exact order of them. Timestamp of the border backup (= the oldest one of recent 'maxbackups' ones) as 'bordermtime' is used to examine whether timestamp can decide exact order of backups.

subrepo: use vfs.dirname instead of os.path.dirname This patch uses "wvfs of the parent repository" ('pwvfs') instead of 'wvfs' of own repository, because 'self._path' is the path to this subrepository as seen from the parent repository.

vfs: add dirname

subrepo: use vfs.basename instead of os.path.basename

vfs: add basename

subrepo: use repo.pathto instead of util.pathto to simplify invocation This centralization into 'repo.pathto()' should reduce the cost of vfs migration around 'getcwd()' and so on in the future.

subrepo: prefetch ctx.repo() for efficiency and centralization 'subrepo.state()' refers same 'ctx.repo()' in many places and times.

revset: rename getkwargs() to getargsdict() This function was added recently at 48919d246a47, but its name was misleading because it processes both positional and keyword arguments.

revset: work around x:y range where x or y is wdir() All revisions must be contiguous in spanset, so we need the special case for the wdir revision.
