Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Carlos Martín Nieto 1c967df3 2013-11-02T00:51:57 remote: fix a couple of leaks
Carlos Martín Nieto 359dce72 2013-11-02T00:05:32 remote: make _ls return the list directly The callback-based method of listing remote references dates back to the beginning of the network code's lifetime, when we didn't know any better. We need to keep the list around for update_tips() after disconnect() so let's make use of this to simply give the user a pointer to the array so they can write straightforward code instead of having to go through a callback.
Carlos Martín Nieto af613ecd 2013-10-28T23:30:45 remote: store dwimed refspecs separately This allows us to add e.g. "HEAD" as a refspec when none are given without overwriting the user's data.
Carlos Martín Nieto 2f03050f 2013-10-26T16:21:31 remote: download HEAD when no refspecs are given The correct behaviour when a remote has no refspecs (e.g. a URL from the command-line) is to download the remote's HEAD. Let's do that. This fixes #1261.
Carlos Martín Nieto d31402a3 2013-09-16T04:20:05 remote: put the _download() callback with the others The text progress and update_tips callbacks are already part of the struct, which was meant to unify the callback setup, but the download one was left out.
Russell Belfer 114f5a6c 2013-06-10T10:10:39 Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
Carlos Martín Nieto 505b5d0c 2013-05-07T16:01:22 remote: correctly interpret tagopt '--tags' When tagopt is set to '--tags', we should only take the default tags refspec into account and ignore any configured ones. Bring the code into compliance.
Carlos Martín Nieto 4330ab26 2013-04-20T04:43:28 remote: handle multiple refspecs A remote can have a multitude of refspecs. Up to now our git_remote's have supported a single one for each fetch and push out of simplicity to get something working. Let the remotes and internal code know about multiple remotes and get the tests passing with them. Instead of setting a refspec, the external users can clear all and add refspecs. This should be enough for most uses, though we're still missing a querying function.

Ben Straub 7d222e13 2012-10-24T13:29:14 Network progress: rename things git_indexer_stats and friends -> git_transfer_progress* Also made git_transfer_progress members more sanely named.
Ben Straub 7bcd9e23 2012-10-19T19:23:32 gitno_buffer: callback on each packet The fetch code takes advantage of this to implement a progress callback every 100kb of transfer.
Ben Straub 216863c4 2012-10-17T14:02:24 Fetch/indexer: progress callbacks
Ben Straub 3028be07 2012-10-16T13:10:27 Add git_indexer_stats field to git_remote Also removing all the *stats parameters from external APIs that don't need them anymore.
Carlos Martín Nieto b2b571ce 2012-10-18T19:05:24 fetch: declare variables at the top of the block
Carlos Martín Nieto f0d2ddbb 2012-10-18T04:31:03 remote: support fetch cancelation Introduce git_remote_stop() which sets a variable that is checked by the fetch process in a few key places. If this is variable is set, the fetch is aborted.
nulltoken 68206c54 2012-10-13T21:00:45 test: fix some memory leaks
Carlos Martín Nieto 3230a44f 2012-09-30T10:56:06 remote: support downloading all tags Also honor remote.$name.tagopt = --tags.
Russell Belfer f335ecd6 2012-08-30T14:24:16 Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
Carlos Martín Nieto 2b175ca9 2012-08-26T00:35:52 indexer: kill git_indexer_stats.data_received It's not really needed with the current code as we have EOS and the sideband's flush to tell us we're done. Keep the distinction between processed and received objects.
Carlos Martín Nieto e03e71da 2012-05-14T17:54:25 network: add sideband support This lets us notify the user of what the remote end is doing while we wait for it to start sending us the packfile.
Carlos Martín Nieto bffa852f 2012-07-13T12:01:11 indexer: recognize and mark when all of the packfile has been downloaded We can't always rely on the network telling us when the download is finished. Recognize it from the indexer itself.
Michael Schubert 7e9f78b5 2012-08-04T15:22:38 remote: add missing include git2/remote.h Otherwise we get an incomplete type error, since git_remote_callbacks isn't declared yet.
Carlos Martín Nieto ad4b5beb 2012-07-25T10:40:59 transport: store the refs in a common area Instad of each transport having its own function and logic to get to its refs, store them directly in transport. Leverage the new gitno_buffer to make the parsing and storing of the refs use common code and get rid of the git_protocol struct.
Carlos Martín Nieto 3e3228b6 2012-07-25T16:30:58 fetch: remove timeout code
Carlos Martín Nieto b49c8f71 2012-07-24T19:03:22 remote: use the same code to control git and http This allows us to add capabilitites to both at the same time, keeps them in sync and removes a lot of code. gitno_buffer now uses a callback to fill its buffer, allowing us to use the same interface for git and http (which uses callbacks).
Carlos Martín Nieto 114dc6e1 2012-07-24T17:10:57 network: implement multi_ack for the git transport
Carlos Martín Nieto 64d01de8 2012-07-24T14:23:16 remote: start moving the protocol to a common area For the transition, http is going to keep its own logic until the git/common code catches up with the implied multi_ack that http has. This also has the side-effect of making the code cleaner and more correct regardingt he protocol.
Carlos Martín Nieto 37159957 2012-06-28T09:33:08 indexer: don't use '/objects/pack/' unconditionally Not everyone who indexes a packfile wants to put it in the standard git repository location.
Carlos Martín Nieto 66024c7c 2012-05-01T00:05:25 http: add https support when GnuTLS is available If it's not available, an error saying so will be returned when trying to use a https:// URL. This also unifies a lot of the network code to use git_transport in many places instead of an socket descriptor.
Vicent Martí 4fbd1c00 2012-05-17T20:35:48 refs: git_reference_listall -> git_reference_list
Carlos Martín Nieto 11678b37 2012-05-09T16:18:13 fetch: filter tag annotation pseudo-refs while generating wants These objects aren't considered as being advertised, so asking for them will cause the remote end to close the connection. This makes the checking in update_tips() unnecessary, because they don't get inserted in the list.
Vicent Martí 3fbcac89 2012-05-02T19:56:38 Remove old and unused error codes
Carlos Martín Nieto dee5515a 2012-04-14T18:34:50 transports: buffer the git requests before sending them Trying to send every single line immediately won't give us any speed improvement and duplicates the code we need for other transports. Make the git transport use the same buffer functions as HTTP.
Carlos Martín Nieto 7a520f5d 2012-04-13T23:19:38 fetch: use the streaming indexer when downloading a pack This changes the git_remote_download() API, but the existing one is silly, so you don't get to complain. The new API allows to know how much data has been downloaded, how many objects we expect in total and how many we've processed.

Russell Belfer 97769280 2011-11-30T11:27:15 Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.
Vicent Marti d88d4311 2011-11-28T08:40:40 remote: Cleanup the remotes code - Hide the remaining transports code - Drop `git_headarray`, switch to using a callback to list refs. Makes the code cleaner.
Vicent Marti 9462c471 2011-11-25T08:16:26 repository: Change ownership semantics The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.
Russell Belfer b762e576 2011-11-17T15:10:27 filebuf: add GIT_FILEBUF_INIT and protect multiple opens and cleanups Update all stack allocations of git_filebuf to use GIT_FILEBUF_INIT and make git_filebuf_open and git_filebuf_cleanup safe to be called multiple times on the same buffer.

Brodie Rao 01ad7b3a 2011-09-06T15:48:45 *: correct and codify various file permissions The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".
Carlos Martín Nieto 2c982daa 2011-10-05T20:09:49 fetch: add a generic pack-download function Taken mostly from the git transport's version, this can be used by any transport that takes its pack data from the network. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>
Carlos Martín Nieto 1636ba5a 2011-09-18T20:07:49 transport: don't have an extra send-wants step It's a bit awkward to run it as an extra step, and HTTP may need to send the wants list several times. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>

Carlos Martín Nieto 4a3b18a6 2011-10-03T22:26:06 A missing refspec is not an error It's rare for a configured remote, but for one given as an URL on the command line, it's more often than not the case. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>

Carlos Martín Nieto 427ca3d3 2011-08-12T22:44:35 Actually implement object negotiation Only signal that we need a pack if we do need it and don't send a want just because it's the first.

Carlos Martín Nieto 22f65b9e 2011-08-10T20:49:43 Move negotiation to the transport There are many ways how a transport might negotiate with the server, so instead of making it fit into the smart protocol model, let the transport do its thing. For now, the git protocol limits itself to send only 160 "have" lines so we don't flood the server. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>
