Carlos Martín Nieto ab8d9242 2014-06-28T06:39:38 Introduce reference transactions A transaction allows you to lock multiple references and set up changes for them before applying the changes all at once (or as close as the backend supports). This can be used for replication purposes, or for making sure some operations run when the reference is locked and thus cannot be changed.
Arthur Schreiber 824f755f 2014-05-20T17:31:53 Refs: Introduce `git_refname_t`.
Arthur Schreiber 68f9d6b2 2014-05-15T22:44:50 Refs: Fix some issue when core.precomposeunicode = true. This fixes two issues I found when core.precomposeunicode is enabled: * When creating a reference with a NFD string, the returned git_reference would return this NFD string as the reference’s name. But when looking up the reference later, the name would then be returned as NFC string. * Renaming a reference would not honor the core.precomposeunicode and apply no normalization to the new reference name.

Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer f10d7a36 2013-12-06T15:53:26 Further callback error check style fixes Okay, I've decided I like the readability of this style much better so I used it everywhere.
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 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
Carlos Martín Nieto f2105129 2013-11-23T14:39:53 refs: expose has_log() on the backend The frontend used to look at the file directly, but that's obviously not the right thing to do. Expose it on the backend and use that function instead.
Carlos Martín Nieto 8d5ec910 2013-11-23T14:13:01 refs: expose a way to ensure a ref has a log Sometimes (e.g. stash) we want to make sure that a log will be written, even if it's not in one of the standard locations. Let's make that easier.
Carlos Martín Nieto a57dd3b7 2013-11-13T18:15:20 reflog: integrate into the ref writing Whenever a reference is created or updated, we need to write to the reflog regardless of whether the user gave us a message, so we shouldn't leave that to the ref frontend, but integrate it into the backend. This also eliminates the race between ref update and writing to the reflog, as we protect the reflog with the ref lock. As an additional benefit, this reflog append on the backend happens by appending to the file instead of parsing and rewriting it.
Carlos Martín Nieto 110df893 2013-11-13T13:36:37 refdb: add a `message` parameter for appending to the log This is as yet unused.

Ben Straub 8f4a8b09 2013-10-28T06:20:28 Merge pull request #1802 from libgit2/cmn/reflog-backend Make reflog part of refdb
Russell Belfer 74353137 2013-10-09T11:57:03 After iconv init reset ref normalize error The iconv init was accidentally clearing the default error state during reference normalization. This resets so that normalization errors will be detected correctly.
Russell Belfer 92dac975 2013-10-08T16:35:57 Make reference lookups apply precomposeunicode Before these changes, looking up a reference would return the same precomposed or decomposed form of the reference name that was used to look it up, so on MacOS which ignores the difference between the two, a single reference could be looked up either way and git_reference_name would return the form of the name that was used to look it up! This change makes lookup always return the precomposed name if core.precomposeunicode is set regardless of which version was used to look it up. The reference iterator was already returning the precomposed form from earlier work. This also updates the CMakeLists.txt rules for enabling iconv usage because the clar tests for this code were actually not being activated properly with the old version. Finally, this moves git_repository_reset_filesystem from include/ git2/repository.h to include/git2/sys/repository.h since it is not really a function that normal library users should have to think about very often.
Carlos Martín Nieto b976f3c2 2013-08-19T13:01:49 reflog: move the reflog implementation into refdb_fs References and their logs are logically coupled, let's make it so in the code by moving the fs-based reflog implementation to live next to the fs-based refs one. As part of the change, make the function take names rather than references, as only the names are relevant when looking up and handling reflogs.

Nikolai Vladimirov 504850cd 2013-08-25T15:59:50 refs: add git_reference_is_tag
Russell Belfer 24c71f14 2013-08-21T14:10:27 Add internal ref set_name fn instead of realloc The refdb_fs implementation calls realloc directly on a reference object when it wants to rename it. It is not a public object, so this doesn't mess with the immutability of references, but it does assume certain constraints on the reference representation. This commit wraps that assumption in an isolated API to isolate it.
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 bb45c57f 2013-03-07T16:38:44 refs: explicitly catch leading slashes It's somewhat common to try to write "/refs/tags/something". There is no easy way to catch it during the main body of the function, as there is no way to distinguish whether it's a leading slash or a double slash somewhere in the middle. Catch this at the beginning so we don't trigger the assert in is_all_caps_and_underscore().
Russell Belfer 0d1b094b 2013-02-26T13:15:06 Fix portability issues on Windows The new tests were not taking core.filemode into account when testing file modes after repo initialization. Fixed that and some other Windows warnings that have crept in.
nulltoken c1b5e8c4 2013-02-15T11:35:33 branch: Make git_branch_remote_name() cope with orphaned heads
Russell Belfer 56543a60 2013-02-15T16:02:45 Clear up warnings from cppcheck The cppcheck static analyzer generates warnings for a bunch of places in the libgit2 code base. All the ones fixed in this commit are actually false positives, but I've reorganized the code to hopefully make it easier for static analysis tools to correctly understand the structure. I wouldn't do this if I felt like it was making the code harder to read or worse for humans, but in this case, these fixes don't seem too bad and will hopefully make it easier for better analysis tools to get at any real issues.

Catch this case in particular to avoid triggering an assertion in the uppercase check which expects us not to pass it an empty string. The existing tests don't catch this as they simply use the NORMAL flag. This fixes #1300.

Scott J. Goldman ef82ff30 2013-01-05T00:46:39 Handle packed refs with no trailing newline I saw a repo in the wild today which had a master branch ref which was packed, but had no trailing newline. Git handled it fine, but libgit2 choked on it. Fix seems simple enough. If we don't see a newline, assume the end of the buffer is the end of the ref line.
Russell Belfer 3865f7f6 2012-12-27T23:23:12 Invalid ref name normalization leaked memory When normalizing a reference name, if there is an error because the name is invalid, then the memory allocated for storing the name could be leaked if the caller was not careful and assumed that the error return code meant that no allocation had occurred. This fixes that by explicitly deallocating the reference name buffer if there is an error in normalizing the name.
