* http-push.c: remove duplicated codeJunio C Hamano2008-06-08
| | | | | | | | | | | | | | | | An earlier commit aa1dbc9 (Update http-push functionality, 2006-03-07) borrowed some code from rev-list.c. This copy and paste made sense back then, because mark_edges_uninteresting(), and its helper mark_edge_parents_uninteresting(), accessed a file scope static variable "revs" in rev-list.c, and http-push.c did not have nor care about such a variable. But these days they are already properly libified and live in list-objects.c and they take "revs" as as an argument. Make use of them and lose 20 or so lines.

* Make walker.fetch_ref() take a struct ref.Daniel Barkalow2008-04-26
| | | | | | | | | | | | | | | | This simplifies a few things, makes a few things slightly more complicated, but, more importantly, allows that, when struct ref can represent a symref, http_fetch_ref() can return one. Incidentally makes the string that http_fetch_ref() gets include "refs/" (if appropriate), because that's how the name field of struct ref works. As far as I can tell, the usage in walker:interpret_target() wouldn't have worked previously, if it ever would have been used, which it wouldn't (since the fetch process uses the hash instead of the name of the ref there).

| * Set proxy override with http_init()Mike Hommey2008-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In transport.c, proxy setting (the one from the remote conf) was set through curl_easy_setopt() call, while http.c already does the same with the http.proxy setting. We now just use this infrastructure instead, and make http_init() now take the struct remote as argument so that it can take the http_proxy setting from there, and any other property that would be added later. At the same time, we make get_http_walker() take a struct remote argument too, and pass it to http_init(), which makes remote defined proxy be used for more than get_refs_via_curl(). We leave out http-fetch and http-push, which don't use remotes for the moment, purposefully.

* | | Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

* http-push: clarify the reason of error from the initial PROPFIND requestJunio C Hamano2008-01-20
| | | | | | | | | | | | | | | | | | The first thing http-push does is a PROPFIND to see if the other end supports locking. The failure message we give is always reported as "no DAV locking support at the remote repository", regardless of the reason why we ended up not finding the locking support on the other end. This moves the code to report "no DAV locking support" down the codepath so that the message is issued only when we successfully get a response to PROPFIND and the other end say it does not support locking. Other failures, such as connectivity glitches and credential mismatches, have their own error message issued and we will not issue "no DAV locking" error (we do not even know if the remote end supports it).

| | | | | | | | | | | | | | Failing instead of silently not updating remote refs makes the things clearer for the user when trying to push on a repository while another person do (or while a dandling locks are waiting for a 10 minutes timeout). When silently not updating remote refs, the user does not even know that git has pushed the objects but leaved the refs as they were before (e.g. a new bunch of commits on branch "master" is uploaded, however the branch by itsel still points on the previous head commit).

* http-push: fix webdav lock leak.Grégoire Barbier2008-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Releasing webdav lock even if push fails because of bad (or no) reference on command line. To reproduce the issue that this patch fixes, prepare a test repository availlable over http+webdav, say at http://myhost/myrepo.git/ Then: $ git clone http://myhost/myrepo.git/ $ cd myrepo $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ Finally, you look at the web server logs, and will find one LOCK query and no UNLOCK query, of course the second one will be in 423 return code instead of 200: 1.2.3.4 - gb [19/Jan/2008:14:24:56 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 200 465 (...) 1.2.3.4 - gb [19/Jan/2008:14:25:10 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 423 363 With this patch, there would have be two UNLOCKs in addition of the LOCKs From the user's point of view: - If you realize that you should have typed e.g. "git push http master" instead of "git push http", you will have to wait for 10 minutes for the lock to expire by its own. - Furthermore, if somebody else is dumb enough to type "git push http" while you need to push "master" branch, then you'll need too to wait for 10 minutes too.
