2008-03-05Teach git-fetch to exploit server side automatic tag followingShawn O. Pearce
If the remote peer upload-pack process supports the include-tag protocol extension then we can avoid running a second fetch cycle on the client side by letting the server send us the annotated tags along with the objects it is packing for us. In the following graph we can now fetch both "tag1" and "tag2" on the same connection that we fetched "master" from the remote when we only have L available on the local side: T - tag1 S - tag2 / / L - o ------ o ------ B \ \ \ \ origin/master master The objects for "tag1" are implicitly downloaded without our direct knowledge. The existing "quickfetch" optimization within git-fetch discovers that tag1 is complete after the first connection and does not open a second connection. Signed-off-by: Shawn O.

2007-11-11push: teach push to pass --verbose option to transport layerSteffen Prohaska
A --verbose option to push should also be passed to the transport layer, i.e. git-send-pack, git-http-push. git push is modified to do so. Signed-off-by: Steffen Prohaska <> Signed-off-by: Junio C Hamano <>

2007-11-03Miscellaneous const changes and utilitiesDaniel Barkalow
The list of remote refs in struct transport should be const, because builtin-fetch will get confused if it changes. The url in git_connect should be const (and work on a copy) instead of requiring the caller to copy it. match_refs doesn't modify the refspecs it gets. get_fetch_map and get_remote_ref don't change the list they get. Allow transport get_refs_list methods to modify the struct transport. Add a function to copy a list of refs, when a function needs a mutable copy of a const list. Add a function to check the type of a ref, as per the code in connect.c Signed-off-by: Daniel Barkalow <> Signed-off-by: Junio C Hamano <>
2007-10-16Merge branch 'master' into db/fetch-packShawn O. Pearce
There's a number of tricky conflicts between master and this topic right now due to the rewrite of builtin-push. Junio must have handled these via rerere; I'd rather not deal with them again so I'm pre-merging master into the topic. Besides this topic somehow started to depend on the strbuf series that was in next, but is now in master. It no longer compiles on its own without the strbuf API. * master: (184 commits) Whip post maintenance series into shape. Minor usage update in setgitperms.perl manual: use 'URL' instead of 'url'. manual: add some markup. manual: Fix example finding commits referencing given content. Fix wording in push definition. Fix some typos, punctuation, missing words, minor markup. manual: Fix or remove em dashes. Add a --dry-run option to git-push. Add a --dry-run option to git-send-pack. Fix in-place editing functions in convert.c instaweb: support for Ruby's WEBrick server instaweb: allow for use of auto-generated scripts Add 'git-p4 commit' as an alias for 'git-p4 submit' hg-to-git speedup through selectable repack intervals git-svn: respect Subversion's [auth] section configuration values gtksourceview2 support for gitview fix contrib/hooks/post-receive-email hooks.recipients error message Support cvs via git-shell rebase -i: use diff plumbing instead of porcelain ...

2007-10-03Restore default verbosity for http fetches.Daniel Barkalow
This adds a verbosity level below 0 for suppressing default messages with --quiet, and makes the default for http be verbose instead of quiet. This matches the behavior of the shell script version of git-fetch. Signed-off-by: Daniel Barkalow <> Signed-off-by: Junio C Hamano <>
2007-09-19Ensure builtin-fetch honors {fetch,transfer}.unpackLimitShawn O. Pearce
The only way to configure the unpacking limit is currently through the .git/config (or ~/.gitconfig) mechanism as we have no existing command line option interface to control this threshold on a per invocation basis. This was intentional by design as the storage policy of the repository should be a repository-wide decision and should not be subject to variations made on individual command executions. Earlier builtin-fetch was bypassing the unpacking limit chosen by the user through the configuration file as it did not reread the configuration options through fetch_pack_config if we called the internal fetch_pack() API directly. We now ensure we always run the config file through fetch_pack_config at least once in this process, thereby setting our unpackLimit properly. Signed-off-by: Shawn O. Pearce <> Signed-off-by: Junio C Hamano <>
2007-09-19Refactor struct transport_ops inlined into struct transportShawn O. Pearce
Aside from reducing the code by 20 lines this refactoring removes a level of indirection when trying to access the operations of a given transport "instance", making the code clearer and easier to follow. It also has the nice effect of giving us the benefits of C99 style struct initialization (namely ".fetch = X") without requiring that level of language support from our compiler. We don't need to worry about new operation methods being added as they will now be NULL'd out automatically by the xcalloc() we use to create the new struct transport we supply to the caller. This pattern already exists in struct walker, so we already have a precedent for it in Git. We also don't really need to worry about any sort of performance decreases that may occur as a result of filling out 4-8 op pointers when we make a "struct transport". The extra few CPU cycles this requires over filling in the "struct transport_ops" is killed by the time it will take Git to actually *use* one of those functions, as most transport operations are going over the wire or will be copying object data locally between two directories.

2007-09-19Remove unnecessary 'fetch' argument from transport_get APIShawn O. Pearce
We don't actually need to know at the time of transport_get if the caller wants to fetch, push, or do both on the returned object. It is easier to just delay the initialization of the HTTP walker until we know we will need it by providing a CURL specific fetch function in the curl_transport that makes sure the walker instance is initialized before use.

2007-09-19Remove pack.keep after ref updates in git-fetchShawn O. Pearce
If we are using a native packfile to perform a git-fetch invocation and the received packfile contained more than the configured limits of fetch.unpackLimit/transfer.unpackLimit then index-pack will output a single line saying "keep\t$sha1\n" to stdout. This line needs to be captured and retained so we can delete the corresponding .keep file ("$GIT_DIR/objects/pack/pack-$sha1.keep") once all refs have been safely updated. This trick has long been in use with and its lower level helper git-fetch--tool as a way to allow index-pack to save the new packfile before the refs have been updated and yet avoid a race with any concurrently running git-repack process. It was unfortunately lost when was converted to pure C and fetch--tool was no longer being invoked. Signed-off-by: Shawn O. Pearce <> Signed-off-by: Junio C Hamano <>
2007-09-19Simplify fetch transport API to just one functionShawn O. Pearce
Commit walkers need to know the SHA-1 name of any objects they have been asked to fetch while the native pack transport only wants to know the names of the remote refs as the remote side must do the name->SHA-1 translation. Since we only have three fetch implementations and one of them (bundle) doesn't even need the name information we can reduce the code required to perform a fetch by having just one function and passing of the filtered list of refs to be fetched. Each transport can then obtain the information it needs from that ref array to construct its own internal operation state. Signed-off-by: Shawn O.

2007-09-19Push code for transport libraryDaniel Barkalow
This moves the code to call push backends into a library that can be extended to make matching fetch and push decisions based on the URL it gets, and which could be changed to have built-in implementations instead of calling external programs.
