2006-09-16Add ftp:// protocol support for git-http-fetchLibravatar Junio C Hamano1-1/+3
Based on Sasha Khapyorsky's patch but adjusted to the refactored "missing target" detection code. It might have been better if the program were called git-url-fetch but it is too late now ;-). Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-16http-fetch.c: consolidate code to detect missing fetch targetLibravatar Junio C Hamano1-8/+15
At a handful places we check two error codes from curl library to see if the file we asked was missing from the remote (e.g. we asked for a loose object when it is in a pack) to decide what to do next. This consolidates the check into a single function. NOTE: the original did not check for HTTP_RETURNED_ERROR when error code is 404, but this version does to make sure 404 is from HTTP and not some other protcol.

2006-09-13http-fetch: fix alternates handling.Libravatar Junio C Hamano1-5/+34
Fetch over http from a repository that uses alternates to borrow from neighbouring repositories were quite broken, apparently for some time now. We parse input and count bytes to allocate the new buffer, and when we copy into that buffer we know exactly how many bytes we want to copy from where. Using strlcpy for it was simply stupid, and the code forgot to take it into account that strlcpy terminated the string with NUL. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-1/+1
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-27free(NULL) is perfectly valid.Libravatar Junio C Hamano1-9/+4
Jonas noticed some places say "if (X) free(X)" which is totally unnecessary. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Libravatar Shawn Pearce1-1/+1
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

2006-08-17Do not use memcmp(sha1_1, sha1_2, 20) with hardcoded length.Libravatar David Rientjes1-3/+3
Introduces global inline: hashcmp(const unsigned char *sha1, const unsigned char *sha2) Uses memcmp for comparison and returns the result based on the length of the hash name (a future runtime decision).

2006-08-11drop length argument of has_extensionLibravatar Rene Scharfe1-1/+1
As Fredrik points out the current interface of has_extension() is potentially confusing. Its parameters include both a nul-terminated string and a length-limited string. This patch drops the length argument, requiring two nul-terminated strings; all callsites are updated. I checked that all of them indeed provide nul-terminated strings. Filenames need to be nul-terminated anyway if they are to be passed to open() etc. The performance penalty of the additional strlen() is negligible compared to the system calls which inevitably surround has_extension() calls. Additionally, change has_extension() to use size_t inside instead of int, as that is the exact type strlen() returns and memcmp() expects.

2006-08-05commit walkers: setup_ident() to record correct committer in ref-log.Libravatar Ramsay Jones1-0/+1
The function pull() in fetch.c calls write_ref_sha1(), which may need committer identity to update the ref-log, so they need to call setup_ident() before calling git_config() function. Acked-by: Shawn Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-27Make pull() support fetching multiple targets at onceLibravatar Petr Baudis1-1/+1
pull() now takes an array of arguments instead of just one of each kind. Currently, no users use the new capability, but that'll change. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-27Make pull() take some implicit data as explicit argumentsLibravatar Petr Baudis1-2/+2
Currently it's a bit weird that pull() takes a single argument describing the commit but takes the write_ref from a global variable. This makes it take that as a parameter as well, which might be nicer for the libification in the future, but especially it will make for nicer code when we implement pull()ing multiple commits at once.

2006-07-10Avoid C99 comments, use old-style C comments instead.Libravatar Pavel Roskin1-3/+3
This doesn't make the code uglier or harder to read, yet it makes the code more portable. This also simplifies checking for other potential incompatibilities. "gcc -std=c89 -pedantic" can flag many incompatible constructs as warnings, but C99 comments will cause it to emit an error.

2006-06-24Rename safe_strncpy() to strlcpy().Libravatar Peter Eriksen1-3/+3
This cleans up the use of safe_strncpy() even more. Since it has the same semantics as strlcpy() use this name instead. Also move the definition from inside path.c to its own file compat/strlcpy.c, and use it conditionally at compile time, since some platforms already has strlcpy(). It's included in the same way as compat/setenv.c. Signed-off-by: Peter Eriksen <s022018@student.dtu.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-06-18Remove ranges from switch statements.Libravatar Florian Forster1-6/+7
Though very nice and readable, the "case 'a'...'z':" construct is not ANSI C99 compliant. This patch unfolds the range in `quote.c' and substitutes the switch-statement with an if-statement in `http-fetch.c' and `http-push.c'.

2006-05-19Log ref updates made by fetch.Libravatar Shawn Pearce1-0/+2
If a ref is changed by http-fetch, local-fetch or ssh-fetch record the change and the remote URL/name in the log for the ref. This requires loading the config file to check logAllRefUpdates. Also fixed a bug in the ref lock generation; the log file name was not being produced right due to a bad prefix length. Signed-off-by: Shawn O.

2006-03-20http-fetch: nicer warning for a server with unreliable 404 statusLibravatar Junio C Hamano1-0/+8
When a repository otherwise properly prepared is served by a dumb HTTP server that sends "No such page" output with 200 status for human consumption to a request for a page that does not exist, the users will get an alarming "File X corrupt" error message. Hint that they might be dealing with such a server at the end and suggest running fsck-objects to check if the result is OK (the pack-fallback code does the right thing in this case so unless a loose object file was actually corrupt the result should check OK).

2006-03-15Fix broken slot reuse when fetching alternatesLibravatar Nick Hengeveld1-0/+4
When fetching alternates, http-fetch may reuse the slot to fetch non-http alternates if http-alternates does not exist. When doing so, it now needs to update the slot's finished status so run_active_slot waits for the non-http alternates request to finish.

2006-02-07http-fetch: Abort requests for objects which arrived in packsLibravatar Mark Wooding1-1/+15
In fetch_object, there's a call to release an object request if the object mysteriously arrived, say in a pack. Unfortunately, the fetch attempt for this object might already be in progress, and we'll leak the descriptor. Instead, try to tidy away the request.

In fill_active_slots() -- if we find an object which has already arrived, say as part of a pack, /don't/ remove it from the list. It's already been prefetched and someone will ask for it later. Just label it as done and carry blithely on. (As it was, the code would dereference a freed object to continue through the list anyway.)

The current http-fetch is rather careless about fd leakage, causing problems while fetching large repositories. This patch does not reserve exhaustiveness, but I covered everything I spotted.

After using cg-update to pull, empty files named *.temp are left in the various subdirectories of .git/objects/. These are created by git-http-fetch to hold data as it's being fetched from the remote repository. They are left behind after a transfer error so that the next time git-http-fetch runs it can pick up where it left off. If they're empty though, it would make more sense to delete them rather than leaving them behind for the next attempt.
