Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Patrick Steinhardt 1eee631d 2016-08-04T13:45:28 refspec: do not set empty rhs for fetch refspecs According to git-fetch(1), "[t]he colon can be omitted when <dst> is empty." So according to git, the refspec "refs/heads/master" is the same as the refspec "refs/heads/master:" when fetching changes. When trying to fetch from a remote with a trailing colon with libgit2, though, the fetch actually fails while it works when the trailing colon is left out. So obviously, libgit2 does _not_ treat these two refspec formats the same for fetches. The problem results from parsing refspecs, where the resulting refspec has its destination set to an empty string in the case of a trailing colon and to a `NULL` pointer in the case of no trailing colon. When passing this to our DWIM machinery, the empty string gets translated to "refs/heads/", which is simply wrong. Fix the problem by having the parsing machinery treat both cases the same for fetch refspecs.

Jeff Hostetler 64e6b5b0 2015-06-29T17:32:22 fix memory leak in refspec.c on errors.
Carlos Martín Nieto 7cd4ba1b 2015-05-22T12:11:42 refspec: make sure matching refspecs have src, dst and input strings When we find out that we're dealing with a matching refspec, we set the flag and return immediately. This leaves the strings as NULL, which breaks the contract. Assign these pointers to a string with the correct values.
Adrien Thebo b523194d 2015-03-04T13:29:13 refspec: set err message on invalid refspec If a refspec could not be parsed, the git_refspec__parse function would return an error value but would not provide additional error information for the callers. This commit amends that function to set a more useful error message.
Carlos Martín Nieto aad638f3 2014-11-07T15:00:11 push: use the common refspec parser There is one well-known and well-tested parser which we should use, instead of implementing parsing a second time. The common parser is also augmented to copy the LHS into the RHS if the latter is empty. The expressions test had to change a bit, as we now catch a bad RHS of a refspec locally.

Carlos Martín Nieto f5287fa6 2014-07-04T17:17:23 refspec: support asterisks in the middle of a pattern We used to assume a refspec would only have an asterisk in the middle of their respective pattern. This has not been a valid assumption for some time now with git. Instead of assuming where the asterisk is going to be, change the logic to treat each pattern as having two halves with a replacement bit in the middle, where the asterisk is.
Carlos Martín Nieto 9ed104a8 2014-07-04T17:16:17 refspec: short-circuit non-pattern refspecs on transform When transforming a non-pattern refspec, we simply need to copy over the opposite string. Move that logic up to the wrapper so we can assume a pattern refspec in the transformation function.

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 528a4e24 2013-04-28T14:16:45 Parse shorthand refspecs as valid Relax the ONELEVEL ref naming rules so the refspec parsing code can ask for 'master' to be considered valid.
Carlos Martín Nieto 1be680c4 2013-04-20T19:13:47 refspec: unify the string and parsed data It used to be separate as an attempt to make the querying easier, but it didn't work out that way, so put all the data together. Add git_refspec_string() as well to get the original string, which is now stored alongside the independent parts.
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.

Vicent Martí cb8a7961 2012-03-07T00:02:55 error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.

Carlos Martín Nieto 279afd2a 2012-01-31T17:21:49 refspec: a ref name includes the refs/ prefix git_refspec_transform_r assumed that the reference name passed would be only a branch or tag name. This is not the case, and we need to take into consideration what's in the refspec's source to know how much of the prefix to ignore.

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 87d9869f 2011-09-19T03:34:49 Tabify everything There were quite a few places were spaces were being used instead of tabs. Try to catch them all. This should hopefully not break anything. Except for `git blame`. Oh well.
Vicent Marti bb742ede 2011-09-19T01:54:32 Cleanup legal data 1. The license header is technically not valid if it doesn't have a copyright signature. 2. The COPYING file has been updated with the different licenses used in the project. 3. The full GPLv2 header in each file annoys me.
Carlos Martín Nieto 63f91e1c 2011-06-22T16:52:30 Add git.git's fnmatch, which is really GNU's and the git__fnmatch wrapper If the strings match, git__fnmatch returns GIT_SUCCESS and GIT_ENOMATCH on failure to match. MSVC fixes: Added a test for _MSC_VER and (in that case) defined HAVE_STRING_H to 1 so it doesn't try to include <strings.h> which doesn't exist in the MSVC world. Moved the function declarations to use the modern inline ones so MSVC doesn't have a fit. Added casts everywhere so MSVC doesn't crap its pants. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>
