| * http-push.c: use a faux remote to pass to http_initAmos King2009-03-19
| | | | | | | | | | | | | | | | | | | | | | This patch allows http_push to use http authentication via prompts. You may notice that there is a remote struct that only contains the url from the repo struct. This struct is a temporary fix for a larger issue, but gets http authentication via prompts out the door, and keeps users from having to store passwords in plain text files.

| * use a hash of the lock token as the suffix for PUT/MOVETay Ray Chuan2009-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After 753bc91 ("Remove the requirement opaquelocktoken uri scheme"), lock tokens are in the URI forms in which they are received from the server, eg. 'opaquelocktoken:', 'urn:uuid:'. However, "start_put" (and consequently "start_move"), which attempts to create a unique temporary file using the UUID of the lock token, inadvertently uses the lock token in its URI form. These file operations on the server may not be successful (specifically, in Windows), due to the colon ':' character from the URI form of the lock token in the file path. This patch uses a hash of the lock token instead, guaranteeing only "safe" characters (a-f, 0-9) are used in the file path. The token's hash is generated when the lock token is received from the server in handle_new_lock_ctx, minimizing the number of times of hashing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code is very inconsistent about which signals are caught for doing cleanup of temporary files and lock files. Some callsites checked only SIGINT, while others checked a variety of death-dealing signals. This patch factors out those signals to a single function, and then calls it everywhere. For some sites, that means this is a simple clean up. For others, it is an improvement in that they will now properly clean themselves up after a larger variety of signals.

However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.

This patch provides a new function ("get_dav_token_headers") that creates these header, saving methods from allocating memory, and from issuing a "curl_slist_append()" call. The temporary string storage given to curl_slist_append() is freed much earlier than the previous code with this patch, but this change is safe, because curl_slist_append() keeps a copy of the given string. In part, this patch also addresses the fact that commit 753bc91 (Remove the requirement opaquelocktoken uri scheme) did not update memory allocations for DAV-related headers.

By leaving the '/' in place, we can avoid this additional step. Incidentally, at least one version of Curl (7.16.3) does not resend credentials when it follows a 301 redirect, so this commit also fixes a bug. Original patch by Tay Ray Chuan <rctay89@gmail.com>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The program calls remote_ls() to get list of files from the server over HTTP; handle_remote_ls_ctx() is used to parse its response to populate "struct remote_ls_ctx" that is returned from remote_ls(). The handle_remote_ls_ctx() function assumed that the server returns a local path in href field, but RFC 4918 (14.7) demand of support full URI (e.g. "http://localhost:8080/repo.git"). This resulted in push failure (e.g. git-http-push issues a PROPFIND request to "/repo.git/alhost:8080/repo.git/refs/" to the server). Signed-off-by: Kirill A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The program flow of pushing over http is: - call lock_remote() to issue a DAV_LOCK request to the server to lock info/refs and branch refs being pushed into; handle_new_lock_ctx() is used to parse its response to populate "struct remote_lock" that is returned from lock_remote(); - send objects; - call unlock_remote() to drop the lock. The handle_new_lock_ctx() function assumed that the server will use a lock token in opaquelocktoken URI scheme, which may have been an Ok assumption under RFC 2518, but under RFC 4918 which obsoletes the older standard it is not necessarily true. This resulted in push failure (often resulted in "cannot lock existing info/refs" error message) when talking to a server that does not use opaquelocktoken URI scheme. Signed-off-by: Kirill A.

Compilation of git is probably broken on PPC too for the same reason. Turns out that the only file requiring openssl/ssl.h and openssl/err.h is imap-send.c. But only moving those problematic includes there doesn't solve the issue as it also includes cache.h which brings in the conflicting local SHA1 header file. As suggested by Jeff King, the best solution is to rename our references to SHA1 functions and structure to something git specific, and define those according to the implementation used.

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().

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: do not get confused by submodulesJohannes Schindelin2008-02-15
| | | | | | | | | | | | | | | | | | | | | | | | When encountering submodules in a tree, http-push should not try sending the respective object. Instead, it should ignore it. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| |/ | | | | | | | | | | | | | | | | | | Before objects are sent, the respective ref is locked. However, without this patch, the lock is lifted before the last object for that ref was sent. As a consequence, the lock data was accessed after the lock structure was free()d. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* 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).
