2012-07-18mw-to-git: check blank credential attributes via lengthLibravatar Jeff King1-1/+1
When writing a credential to git-credential, we omit fields that do not have a true value. This will skip empty or undefined fields (which we want), but will also accidentally skip usernames or passwords which happen to have a non-true value (e.g., "0"). Be more careful by checking for non-zero length. Signed-off-by: Jeff King <peff@peff.net> Acked-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-07-17git-remote-mediawiki: allow page names with a ':'Libravatar Matthieu Moy2-16/+53
Traditionnally, pages named Foo:Bar are page 'Bar' in namespace 'Foo'. However, it is also possible to call a page Foo:Bar if 'Foo' is not a namespace. In this case, the actual name of the page is 'Foo:Bar', in the main namespace. Since we can't tell with only the filename, query the wiki for a namespace 'Foo' in these cases, but deal with the case where no such namespace is found.

The only way to fetch new revisions from a wiki before this patch was to query each page for new revisions. This is good when tracking a small set of pages on a large wiki, but very inefficient when tracking many pages on a wiki with little activity.

install_wiki.sh allows the user to install a MediaWiki instance in a single shell command. Like "git instaweb", it configures and launches lighttpd without requiring root priviledges. To simplify database management, it uses SQLite, which doesn't require a running daemon, and allows reseting the database by simply replacing a single file. This allows install_wiki to also defines a function wiki_reset which clear all content of the previously created wiki, which will be very useful to run several indepenant tests on the same wiki.

2012-06-19completion: respect $GIT_DIRLibravatar SZEDER Gábor1-0/+3
The __gitdir() helper function finds out the path of the git repository by running 'git rev-parse --git-dir'. However, it has a shortcut first to avoid the overhead of running a git command in a subshell when the current directory is at the top of the work tree, i.e. when it contains a '.git' subdirectory. If the 'GIT_DIR' environment variable is set then it specifies the path to the git repository, and the autodetection of the '.git' directory is not necessary. However, $GIT_DIR is only taken into acocunt by 'git rev-parse --git-dir', and the check for the '.git' subdirectory is performed first, so it wins over the path given in $GIT_DIR. There are several completion (helper) functions that depend on __gitdir(), and when the above case triggers the completion script will do weird things, like offering refs, aliases, or stashes from a different repository, or displaying wrong or broken prompt, etc. So check first whether $GIT_DIR is set, and only proceed with checking the '.git' directory in the current directory if it isn't. 'git rev-parse' would also check whether the path in $GIT_DIR is a proper '.git' directory, i.e. 'HEAD', 'refs/', and 'objects/' are present and accessible, but we don't have to be that thorough for the bash prompt. And we've lived with an equally permissive check for '.git' in the current working directory for years anyway.

In git-blame-filter and git-blame-create-overlay we want to save (along with the values of point and mark) the current-buffer in scope when calling the functions. The idiom (save-excursion (set-buffer buf) ...) will correctly restore the correct buffer, but will not save the values of point and mark in buf (only in the buffer current when the save-excursion call is executed). The intention of these functions is to save the current buffer from the calling scope and the values of point and mark in the buffer they are modifying.

Commit 7f02f3d7 (completion: rename internal helpers _git and _gitk, 2012-05-19) renamed said functions to _main_git() and _main_gitk(), respectively. By convention the name of our git-completion-specific functions start with '_git' or '__git' prefix, so rename those functions once again to put them back into our "namespace". Use the two underscore prefix, because _git_main() could be mistaken for the completion function of the (not yet existing) 'git main' command.

2012-06-07Merge branch 'cr/persistent-https'Libravatar Junio C Hamano7-0/+860
A remote helper that acts as a proxy and caches ssl session for the https:// transport is added to the contrib/ area. By Colby Ranger * cr/persistent-https: Add persistent-https to contrib
2012-05-30Add persistent-https to contribLibravatar Colby Ranger7-0/+860
Git over HTTPS has a high request startup latency, since the SSL negotiation can take up to a second. In order to reduce this latency, connections should be left open to the Git server across requests (or invocations of the git commandline). Reduce SSL startup latency by running a daemon job that keeps connections open to a Git server. The daemon job (git-remote-persistent-https--proxy) is started on the first request through the client binary (git-remote-persistent-https) and remains running for 24 hours after the last request, or until a new daemon binary is placed in the PATH. The client determines the daemon's HTTP address by communicating over a UNIX socket with the daemon. From there, the rest of the Git protocol work is delegated to the "git-remote-http" binary, with the environment's http_proxy set to the daemon. Accessing /pub/scm/linux/kernel/git/torvalds/linux repository hosted at kernel.googlesource.com with "git ls-remote" over https:// and persistent-https:// 5 times shows that the first request takes about the same time (0.193s vs 0.208s---there is a slight set-up cost for the local proxy); as expected, the other four requests are much faster (~0.18s vs ~0.08s). Incidentally, this also has the benefit of HTTP keep-alive working across Git command invocations. Its common for servers to use a 5 minute keep-alive on an HTTP 1.1 connection. Git-over-HTTP commonly uses Transfer-Encoding: chunked on replies, so keep-alive will generally just work, even though a pack stream's length isn't known in advance. Because the helper is an external process holding that connection open, we also benefit from being able to reuse an existing TCP connection to the server. The same "git ls-remote" test against http:// vs persistent-https:// URL shows that the former takes ~0.09s while the first request for the latter is about 0.134s with set-up cost, and subsequent requests are ~0.065s, shaving around one RTT to the server.
