Carlos Martín Nieto 38d338b2 2014-04-26T18:15:39 pack-objects: always write out the status in write_one() Make sure we set the output parameter to a value.
Jacques Germishuys 48e60ae7 2014-04-21T11:23:29 Don't redefine the same callback types, their signatures may change
Carlos Martín Nieto a14aa1e7 2014-03-04T20:09:17 pack-objects: free memory safely A few fixes have accumulated in this area which have made the freeing of data a bit muddy. Make sure to free the data only when needed and once. When we are going to write a delta to the packfile, we need to free the data, otherwise leave it. The current version of the code mixes up the checks for po->data and po->delta_data.
Russell Belfer d9b04d78 2014-01-29T15:02:35 Reorganize zstream API and fix wrap problems There were some confusing issues mixing up the number of bytes written to the zstream output buffer with the number of bytes consumed from the zstream input. This reorganizes the zstream API and makes it easier to deflate an arbitrarily large input while still using a fixed size output.

Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer c7b3e1b3 2013-12-06T15:42:20 Some callback error check style cleanups I find this easier to read...
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.

Vicent Martí ac5e507c 2013-11-01T09:31:52 Merge pull request #1918 from libgit2/cmn/indexer-naming indexer: remove the stream infix
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.

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).
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).
Rémi Duraffort 050af8bb 2013-07-15T16:00:00 pack: fix memory leak in error path
Russell Belfer 1a42dd17 2013-05-31T14:13:11 Mutex init can fail It is obviously quite a serious problem if this happens, but mutex initialization can fail and we should detect it. It's a bit like a memory allocation failure, in that you're probably pretty screwed if this occurs, but at least we'll catch it.
Michael Schubert 563c19a9 2013-05-11T11:36:29 packbuilder: also write index in git_packbuilder_write git_packbuilder_write() used to write a packfile to the passed file path. Instead, ask for a destination directory and create both the packfile and an index, as most users probably do expect.

Carlos Martín Nieto 0e040c03 2013-03-03T14:50:47 indexer: use a hashtable for keeping track of offsets These offsets are needed for REF_DELTA objects, which encode which object they use as a base, but not where it lies in the packfile, so we need a list. These objects are mostly from older packfiles, before OFS_DELTA was widely spread. The time spent in indexing these packfiles is greatly reduced, though remains above what git is able to do.
