templatefilters: add filter to convert date to local date (issue1674) Issue1674 suggests the localdate filter be applied as default to log, but this patch only introduces the filter, not the changed default behaviour.

url: use CONNECT for HTTPS connections through HTTP proxy (issue967) urllib2 and httplib does not support using CONNECT proxy requests, but only regular requests over the proxy. This does not work with HTTPS requests as they typically require that the client issues a CONNECT to the proxy to give a direct connection to the remote HTTPS server. This is solved by duplicating some of the httplib functionality and tying it together with the keepalive library such that a HTTPS connection that need to be proxied can be proxied by letting a connection be established to the proxy server and then subsequently performing the normal request to the specified server through the proxy server. As it stands, the code also purports to support HTTPS proxies, i.e. proxies that you connect to using SSL. These are extremely rare and nothing is done to ensure that CONNECT requests can be made to these as that would require multiple SSL handshakes. This use case is also not supported by most other contemporary web tools like curl and Firefox3.

tests: add tests for new pre-push logic (issue736) Co-contributor: Henrik Stuart <henrik.stuart@edlund.dk>

named branches: improve pre-push logic (issue736) Each named branch is considered separately, and the push is allowed if no new branch heads are created for any named branch to be pushed. Due to some tests's use of --debug, their output will change after this addition. This has been fixed as well. Co-contributor: Henrik Stuart <henrik.stuart@edlund.dk>

named branches: client branchmap wire protocol support (issue736) Co-contributor: Sune Foldager <cryo@cyanite.org>

named branches: server branchmap wire protocol support (issue736) The repository command, 'branchmap', returns a dictionary, branchname -> [branchheads], and will be implemented for localrepo, httprepo and sshrepo. The following wire format is used for returning data: branchname1 branch1head2 branch1head2 ... branchname2 ... ... Branch names are URL encoded to escape white space, and branch heads are sent as hex encoded node ids. All branches and all their heads are sent. The background and motivation for this command is the desire for a richer named branch semantics when pushing changesets. The details are explained in the original proposal which is included below. 1. BACKGROUND The algorithm currently implemented in Mercurial only considers the graph theoretical heads when determining whether new heads are created, rather than using the branch heads as a count (the algorithm considers a branch head effectively closed when it is merged into another branch or a new named branch is started from that point onward). Our particular problem with the algorithm is that we'd like to see the following case working without forcing a push: Upsteam has: (0:dev) ---- (1:dev) \ `--- (2:stable) Someone merges stable into dev: (0:dev) ---- (1:dev) ------(3:dev) \ / `--- (2:stable) --------´ This can be pushed without --force (as it should). Now someone else does some coding on stable (a bug fix, say): (0:dev) ---- (1:dev) ------(3:dev) \ / `--- (2:stable) ---------´---------(4:stable) This time we need --force to push. We allow this to be pushed without using --force by getting all the remote branch heads (by extending the wire protocol with a new function). We would, furthermore, also prefer if it is impossible to push a new branch without --force (or a later --newbranch option so --force isn't shoe-horned into too many disparate functions, if need be), except of course in the case where the remote repository is empty. This is what our patches accomplish. 2. ALTERNATIVES We have, of course, considered some alternatives to reconstructing enough information to decide whether we are creating new remote branch heads, before we added the new wire protocol command. 2.1. LOOKUP ON REMOTE The main alternative is to use the information from remote.heads() and remote.lookup() to try to reconstruct enough graph information to decide whether we are creating new heads. This is not adequate as illustrated below. Remember that each lookup is typically a request-response pair over SSH or HTTP(S). If we have a simple repository at the remote end like this: (0:dev) ---- (1:dev) ---- (3:stable) \ `--- (2:dev) then remote.heads() will yield [2, 3]. Assume we have nodes [0, 1, 2] locally and want to create a new node, 4:dev, as a descendant from (1:dev), which should be OK as 1:dev is a branch head. If we do remote.lookup('dev') we will get [2]. Thus, we can get information about whether a branch exists on the remote server or not, but this does not solve our problem of figuring out whether we are creating new heads or not. Pushing 4:dev ought to be OK, since after the push, we still only have two heads on branch a. Using remote.lookup() and remote.heads() is thus not adequate to consistently decide whether we are creating new remote heads (e.g. in this situation the latter would never return 1:dev). 2.2. USING INCOMING TO RECONSTRUCT THE GRAPH An alternative would be to use information equivalent to hg incoming to get the full remote graph in addition to the local graph. To do this, we would have to get a changegroup(subset) bundle representing the remote end (which may be a substantial amount of data), getting the branch heads from an instantiated bundlerepository, deleting the bundle, and finally, we can compute the prepush logic. While this is backwards compatible, it will cause a possibly substantial slowdown of the push command as it first needs to pull in all changes. 3. FURTHER ARGUMENTS IN FAVOUR OF THE BRANCHMAP WIRE-PROTOCOL EXTENSION Currently, the commands incoming and pull, work based on the tip of a given branch if used with "-r branchname", making it hard to get all revisions of a certain branch only (if it has multiple heads). This can be solved by requesting the remote's branchheads and letting the revisions to be used with the command be these heads. This can be done by extending the commands with a new option, e.g.: hg pull -b branchname which will be turned into the equivalent of: hg pull -r branchhead1 -r branchhead2 -r branchhead3 We have a simple follow-up patch that can do this ready as well (although not submitted yet as it is pending the acceptance of the branch patch). 4. WRAP-UP We generally find that the branchmap wire protocol extension can provide better named branch support to Mercurial. Currently, some things, like the initial push scenario in this mail, are fairly counter-intuitive, and the more often you have to force push, the more it is likely you will get a lot of spurious and unnecessary merge nodes. Also, restricting incoming and pull to all changes on a branch rather than changes on the tip-most head would be a sensible extension to making named branches a first class citizen in Mercurial. Currently, named branches sometimes feel like a late-coming unwanted step-child. We have run it in a production environment for a while, with fewer multiple heads occurring in our repositories and fewer confused users as a result. Also, it fixes the long-standing issue 736.

inotify: Removing the unnecessary "inotifyserver" class variable.

inotify: set a flag so a failed inotify query doesn't get repeated. If, for some reason, we can't get the inotify server to start, it's better to disable inotify queries for the instance to avoid trying over and over to start the server, which takes time. Just fall back on repo.status()

inotify: introduce debuginotify, which lists which paths are under watch

inotify: put STAT-specific query answer generation part in its own method

inotify: change protocol so that different query types can be supported.

inotify: Separate query sending logic from Server starting. Use a decorator around the public statusquery method of Client: start_server(query_to_server): try: query_to_server() except QueryFailed: [error recovery, inotify Server (re)starting] query_to_server() This way, introducing a new xxxquery Client method is easy: one has only to code the protocol part of xxxquery, ignoring errors, and decorating it using start_server to handle server recovery and (re)starts

inotify: modular architecture for inotify clients Put the socket init, query generation and response analysis in a more generic client class.

setup: add missing newline in warning

setup: read .hg_archival.txt for version info (issue1670) Previously, setup.py was enhanced to identify the Mercurial version from either .hg/ or mercurial/__version__.py. When archives are created using 'hg archive' or via hgweb, neither of those options are available. However, there is a .hg_archival.txt file in the root of the archive that has the information. This patch enhances setup.py to identify the Mercurial version from the .hg_archival.txt file when there is no .hg/ or mercurial/__version__.py available.

setup.py: subprocess instead of os.popen, sys.stderr.write instead of print Also check that .hg is a directory.
