Carlos Martín Nieto 9331f98a 2014-05-22T12:52:31 smart: initialize the error variable
Carlos Martín Nieto 4c4408c3 2014-05-22T12:28:39 Plug leaks and fix a C99-ism We have too many places where we repeat free code, so when adding the new free to the generic code, it didn't take for the local transport. While there, fix a C99-ism that sneaked through.
Vicent Marti a5982644 2014-05-22T02:28:42 Merge pull request #2376 from libgit2/cmn/remote-symref Add support for the symref extension
Carlos Martín Nieto 8156835d 2014-05-20T09:29:39 smart: store reported symrefs The protocol has a capability which allows the server to tell us which refs are symrefs, so we can e.g. know which is the default branch. This capability is different from the ones we already support, as it's not setting a flag to true, but requires us to store a list of refspec-formatted mappings. This commit does not yet expose the information in the reference listing.
Carlos Martín Nieto 04865aa0 2014-05-21T10:01:44 local transport: expose the symref data When using the local transport, we always have the symbolic information available, so fill it.
Carlos Martín Nieto 306475eb 2014-05-20T09:55:26 remote: expose the remote's symref mappings Add a symref_target field to git_remote_head to expose the symref mappings to the user.
Carlos Martín Nieto ac11219b 2014-05-19T16:54:19 smart: send a flush when we disconnect The git server wants to hear a flush from us when we disconnect, particularly when we want to perform a fetch but are up to date.

Vicent Marti 5ca410b9 2014-04-23T07:13:49 Merge pull request #2283 from phkelley/win32_fs Win32: UTF-8 <-> WCHAR conversion overhaul
Carlos Martín Nieto bc0a6198 2014-04-19T15:52:58 transports: allow the creds callback to say it doesn't exist Allow the credentials callback to return GIT_PASSTHROUGH to make the transports code behave as though none was set. This should make it easier for bindings to behave closer to the C code when there is no credentials callback set at their level.

Jacques Germishuys 9effa2fb 2014-04-20T19:19:13 Fire progress callbacks also for pushes. It's not very useful to only know that a pre-receive hook has declined a push, you probably want to know why.

Jacques Germishuys 478408c0 2014-04-17T23:03:44 Introduce git_cred_ssh_interactive_new() This allows for keyboard-interactive based SSH authentication
Carlos Martín Nieto bd270b70 2014-04-18T17:08:10 cred: tighten username rules The ssh-specific credentials allow the username to be missing. The idea being that the ssh transport will then use the username provided in the url, if it's available. There are two main issues with this. The credential callback already knows what username was provided by the url and needs to figure out whether it wants to ask the user for it or it can reuse it, so passing NULL as the username means the credential callback is suspicious. The username provided in the url is not in fact used by the transport. The only time it even considers it is for the user/pass credential, which asserts the existence of a username in its constructor. For the ssh-specific ones, it passes in the username stored in the credential, which is NULL. The libssh2 macro we use runs strlen() against this value (which is no different from what we would be doing ourselves), so we then crash. As the documentation doesn't suggest to leave out the username, assert the need for a username in the code, which removes this buggy behavior and removes implicit state. git_cred_has_username() becomes a blacklist of credential types that do not have a username. The only one at the moment is the 'default' one, which is meant to call up some Microsoft magic.

Carlos Martín Nieto 0b28217b 2014-01-15T12:51:31 refs: remove the _with_log differentiation Any well-behaved program should write a descriptive message to the reflog whenever it updates a reference. Let's make this more prominent by removing the version without the reflog parameters.
Russell Belfer 9cfce273 2013-12-12T12:11:38 Cleanups, renames, and leak fixes This renames git_vector_free_all to the better git_vector_free_deep and also contains a couple of memory leak fixes based on valgrind checks. The fixes are specifically: failure to free global dir path variables when not compiled with threading on and failure to free filters from the filter registry that had not be initialized fully.
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.
Russell Belfer dab89f9b 2013-12-04T21:22:57 Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
Russell Belfer 9f77b3f6 2013-11-25T14:21:34 Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Vicent Martí 6414fd33 2013-11-11T06:47:15 Merge pull request #1956 from libgit2/cmn/fetch-default-head Remote revamp (director's cut)
Carlos Martín Nieto a6192d7c 2013-11-11T15:32:13 remote: update head list on push A previous commit forgot to update the head list after push as well, leading to wrong output of git_remote_ls().
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 a7382aa2 2013-10-26T16:52:54 remote: give up after 256 failures to find a common object This avoids sending our whole history bit by bit to the remote in cases where there is no common history, just to give up in the end. The number comes from the canonical implementation.

Carlos Martín Nieto 2f8c481c 2013-10-08T16:22:21 protocol: basic support for multi_ack_detailed This tells the server that we speak it, but we don't make use of its extra information to determine if there's a better place to stop negotiating. In a somewhat-related change, reorder the capabilities so we ask for them in the same order as git does. Also take this opportunity to factor out a fairly-indented portion of the negotiation logic.
Carlos Martín Nieto a6154f21 2013-10-30T15:00:05 indexer: remove the stream infix It was there to keep it apart from the one which read in from a file on disk. This other indexer does not exist anymore, so there is no need for anything other than git_indexer to refer to it. While here, rename _add() function to _append() and _finalize() to _commit(). The former change is cosmetic, while the latter avoids talking about "finalizing", which OO languages use to mean something completely different.

Carlos Martín Nieto 70a8c78f 2013-10-23T12:08:54 Rename the ssh credentials The names from libssh2 are somewhat obtuse for us. We can simplify the usual key/passphrase credential's name, as well as make clearer what the custom signature function is.

Jameson Miller 5b188225 2013-10-02T13:45:32 Support cancellation in push operation This commit adds cancellation for the push operation. This work consists of: 1) Support cancellation during push operation - During object counting phase - During network transfer phase - Propagate GIT_EUSER error code out to caller 2) Improve cancellation support during fetch - Handle cancellation request during network transfer phase - Clear error string when cancelled during indexing 3) Fix error handling in git_smart__download_pack Cancellation during push is still only handled in the pack building and network transfer stages of push (and not during packbuilding).
Carlos Martín Nieto e3c131c5 2013-09-16T05:02:25 remote: move the credentials callback to the struct Move this one as well, letting us have a single way of setting the callbacks for the remote, and removing fields from the clone options.
Vicent Martí fba14763 2013-09-30T15:03:35 Merge pull request #1879 from libgit2/redir-refactor Redir refactor
Jameson Miller b176eded 2013-09-19T14:52:57 Initial Implementation of progress reports during push This adds the basics of progress reporting during push. While progress for all aspects of a push operation are not reported with this change, it lays the foundation to add these later. Push progress reporting can be improved in the future - and consumers of the API should just get more accurate information at that point. The main areas where this is lacking are: 1) packbuilding progress: does not report progress during deltafication, as this involves coordinating progress from multiple threads. 2) network progress: reports progress as objects and bytes are going to be written to the subtransport (instead of as client gets confirmation that they have been received by the server) and leaves out some of the bytes that are transfered as part of the push protocol. Basically, this reports the pack bytes that are written to the subtransport. It does not report the bytes sent on the wire that are received by the server. This should be a good estimate of progress (and an improvement over no progress).

Russell Belfer eb0ff130 2013-09-24T14:07:08 Disconnect path string to preserve after redirect The subtransport path was relying on pointing to data owned by the remote which meant that after a redirect, the updated path was getting lost for future requests. This updates the http transport to strdup the path and maintain its own lifetime. This also pulls responsibility for parsing the URL back into the http transport and isolates the functions that parse and free that connection data so that they can be reused between the initial parsing and the redirect parsing.
