2005-06-05[PATCH] pull: gracefully recover from delta retrieval failure.Junio C Hamano
This addresses a concern raised by Jason McMullan in the mailing list discussion. After retrieving and storing a potentially deltified object, pull logic tries to check and fulfil its delta dependency. When the pull procedure is killed at this point, however, there was no easy way to recover by re-running pull, since next run would have found that we already have that deltified object and happily reported success, without really checking its delta dependency is satisfied. This patch introduces --recover option to git-*-pull family which causes them to re-validate dependency of deltified objects we are fetching. A new test t5100-delta-pull.sh covers such a failure mode. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-02[PATCH] Handle deltified object correctly in git-*-pull family.Junio C Hamano
When a remote repository is deltified, we need to get the objects that a deltified object we want to obtain is based upon. The initial parts of each retrieved SHA1 file is inflated and inspected to see if it is deltified, and its base object is asked from the remote side when it is. Since this partial inflation and inspection has a small performance hit, it can optionally be skipped by giving -d flag to git-*-pull commands. This flag should be used only when the remote repository is known to have no deltified objects. Rsync transport does not have this problem since it fetches everything the remote side has.

2005-05-22Include file cleanups..Linus Torvalds
Add <limits.h> to the include files handled by "cache.h", and remove extraneous #include directives from various .c files. The rule is that "cache.h" gets all the basic stuff, so that we'll have as few system dependencies as possible.
2005-05-18[PATCH] Kill a bunch of pointer sign warnings for gcc4Brian Gerst
- Raw hashes should be unsigned char. - String functions want signed char. - Hash and compress functions want unsigned char. Signed-off By: Brian Gerst <bgerst@didntduck.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-06Implement -v (verbose) option for pull methods other than local transport.Junio C Hamano
This moves the private "say()" function to pull.c, renames it to "pull_say()", and introduces a global variable "get_verbosely" that makes the pull backends report what they fetch. The -v option is added to git-rpull and git-http-pull to match git-local-pull. The documentation is updated to describe these pull commands. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-05-02[PATCH] Do not call fetch() when we have it.Junio C Hamano
Currently pull() calls fetch() without checking whether we have the wanted object but all of the existing fetch() implementations perform this check and return success themselves. This patch moves the check to the caller. I will be sending a trivial git-local-pull which depends on this in the next message.

2005-04-30[PATCH] Split out "pull" from particular methodsDaniel Barkalow
The method for deciding what to pull is useful separately from any of the ways of actually fetching the objects. So split out "pull" functionality from http-pull and rpull Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-26[PATCH] introduce xmalloc and xreallocChristopher Li
Introduce xmalloc and xrealloc to die gracefully with a descriptive message when out of memory, rather than taking a SIGSEGV. Signed-off-by: Christopher Li<chrislgit@chrisli.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-24[PATCH] Various transport programsDaniel Barkalow
This patch adds three similar and related programs. http-pull downloads objects from an HTTP server; rpull downloads objects by using ssh and rpush on the other side; and rpush uploads objects by using ssh and rpull on the other side. The algorithm should be sufficient to make the network throughput required depend only on how much content is new, not at all on how much content the repository contains. The combination should enable people to have remote repositories by way of ssh login for authenticated users and HTTP for anonymous access.
