It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

As part of this, git ignore support was extended to support push and pop of directory-based ignore files as the working directory is being traversed (so the array of ignores does not have to be recreated at each directory during traveral). There are a number of other small utility functions in buffer, path, vector, and fileops that are included in this patch that made the iterator implementation cleaner. --- src/attr.c | 70 ++++-- src/attr.h | 7 + src/buffer.c | 8 +- src/buffer.h | 1 + src/fileops.c | 18 ++ src/fileops.h | 7 +- src/ignore.c | 114 +++++++--- src/ignore.h | 24 +- src/iterator.c | 506 +++++++++++++++++++++++++++++++++++++++++ src/iterator.h | 94 ++++++++ src/path.c | 65 ++++++ src/path.h | 32 +++ src/vector.c | 32 +++ src/vector.h | 7 + tests-clar/diff/diff_helpers.c | 22 ++ tests-clar/diff/diff_helpers.h | 4 + tests-clar/diff/iterator.c | 362 +++++++++++++++++++++++++++++ 17 files changed, 1312 insertions(+), 61 deletions(-) create mode 100644 src/iterator.c create mode 100644 src/iterator.h create mode 100644 tests-clar/diff/diff_helpers.c create mode 100644 tests-clar/diff/diff_helpers.h create mode 100644 tests-clar/diff/iterator.c diff --git a/src/attr.c b/src/attr.c index 17571f6a8..a7c65f94c 100644 --- a/src/attr.c +++ b/src/attr.c @@ -218,6 +218,48 @@ int git_attr_cache__is_cached(git_repository *repo, const char *path) return (git_hashtable_lookup(repo->attrcache.files, cache_key) == NULL); } +int git_attr_cache__lookup_or_create_file( + git_repository *repo, + const char *key, + const char *filename, + int (*loader)(git_repository *, const char *, git_attr_file *), + git_attr_file **file_ptr) +{ + int error; + git_attr_cache *cache = &repo->attrcache; + git_attr_file *file = NULL; + + file = git_hashtable_lookup(cache->files, key); + if (file) { + *file_ptr = file; + return GIT_SUCCESS; + } + + if (loader && git_path_exists(filename) != GIT_SUCCESS) { + *file_ptr = NULL; + return GIT_SUCCESS; + } + + if ((error = git_attr_file__new(&file)) < GIT_SUCCESS) + return error; + + if (loader) + error = loader(repo, filename, file); + else + error = git_attr_file__set_path(repo, key, file); + + if (error == GIT_SUCCESS) + error = git_hashtable_insert(cache->files, file->path, file); + + if (error < GIT_SUCCESS) { + git_attr_file__free(file); + file = NULL; + } + + *file_ptr = file; + return error; +} + /* add git_attr_file to vector of files, loading if needed */ int git_attr_cache__push_file( git_repository *repo, @@ -226,16 +268,14 @@ int git_attr_cache__push_file( const char *filename, int (*loader)(git_repository *, const char *, git_attr_file *)) { - int error = GIT_SUCCESS; - git_attr_cache *cache = &repo->attrcache; + int error; git_buf path = GIT_BUF_INIT; git_attr_file *file = NULL; - int add_to_cache = 0; const char *cache_key; if (base != NULL) { if ((error = git_buf_joinpath(&path, base, filename)) < GIT_SUCCESS) - goto cleanup; + return error; filename = path.ptr; } @@ -244,28 +284,12 @@ int git_attr_cache__push_file( if (repo && git__prefixcmp(cache_key, git_repository_workdir(repo)) == 0) cache_key += strlen(git_repository_workdir(repo)); - file = git_hashtable_lookup(cache->files, cache_key); - if (file == NULL && git_path_exists(filename) == GIT_SUCCESS) { - if ((error = git_attr_file__new(&file)) == GIT_SUCCESS) { - if ((error = loader(repo, filename, file)) < GIT_SUCCESS) { - git_attr_file__free(file); - file = NULL; - } - } - add_to_cache = (error == GIT_SUCCESS); - } + error = git_attr_cache__lookup_or_create_file( + repo, cache_key, filename, loader, &file); - if (error == GIT_SUCCESS && file != NULL) { - /* add file to vector, if we found it */ + if (error == GIT_SUCCESS && file != NULL) error = git_vector_insert(stack, file); - /* add file to cache, if it is new */ - /* do this after above step b/c it is not critical */ - if (error == GIT_SUCCESS && add_to_cache && file->path != NULL) - error = git_hashtable_insert(cache->files, file->path, file); - } - -cleanup: git_buf_free(&path); return error; } diff --git a/src/attr.h b/src/attr.h index 6ae2e28dc..5dbbb2366 100644 --- a/src/attr.h +++ b/src/attr.h @@ -20,6 +20,13 @@ extern int git_attr_cache__init(git_repository *repo); extern int git_attr_cache__insert_macro( git_repository *repo, git_attr_rule *macro); +extern int git_attr_cache__lookup_or_create_file( + git_repository *repo, + const char *key, + const char *filename, + int (*loader)(git_repository *, const char *, git_attr_file *), + git_attr_file **file_ptr); + extern int git_attr_cache__push_file( git_repository *repo, git_vector *stack, diff --git a/src/buffer.c b/src/buffer.c index 7a186ebd8..183da7c5f 100644 --- a/src/buffer.c +++ b/src/buffer.c @@ -213,6 +213,12 @@ void git_buf_truncate(git_buf *buf, ssize_t len) } } +void git_buf_rtruncate_at_char(git_buf *buf, char separator) +{ + int idx = git_buf_rfind_next(buf, separator); + git_buf_truncate(buf, idx < 0 ?

This is such a common pattern that it really cleans up usage. Second, for workdir iterators, this removes automatically iterating into directories. That seemed like a good idea, but when an entirely new directory hierarchy is introduced into the workdir, there is no reason to iterate into it if there are no corresponding entries in the tree/index that it is being compared to. This second change actually wasn't a lot of code because not descending into directories was already the behavior for ignored directories. This just extends that to all directories. --- src/iterator.c | 63 ++++++++++++++++++++++++++++------------------ src/iterator.h | 33 +++++++++++++----------- tests-clar/diff/iterator.c | 14 ++++++----- 3 files changed, 66 insertions(+), 44 deletions(-) diff --git a/src/iterator.c b/src/iterator.c index 8511d53eb..805ff643e 100644 --- a/src/iterator.c +++ b/src/iterator.c @@ -80,7 +80,7 @@ static int expand_tree_if_needed(git_iterator_tree *ti) te = git_tree_entry_byindex(tree, tree_idx);

Additionally, all of the static functions had their 'git_' prefix removed, and a lot of other unnecessary changes were removed from the original patch. --- src/ignore.c | 2 +- src/iterator.c | 431 ++++++++++++++++++++++++++----------------------------- src/path.c | 20 ++- src/path.h | 6 +- src/repository.c | 10 +- src/vector.c | 33 +---- src/vector.h | 3 +- 7 files changed, 221 insertions(+), 284 deletions(-) diff --git a/src/ignore.c b/src/ignore.c index ecdd76005..30f86b822 100644 --- a/src/ignore.c +++ b/src/ignore.c @@ -147,7 +147,7 @@ int git_ignore__pop_dir(git_ignores *ign) if (ign->ign_path.length > 0) { git_attr_file *file = git_vector_last(&ign->ign_path); if (git__suffixcmp(ign->dir.ptr, file->path) == 0) - git_vector_pop(&ign->ign_path, NULL); + git_vector_pop(&ign->ign_path); git_buf_rtruncate_at_char(&ign->dir, '/'); } return GIT_SUCCESS; diff --git a/src/iterator.c b/src/iterator.c index 805ff643e..c2b88ab84 100644 --- a/src/iterator.c +++ b/src/iterator.c @@ -10,36 +10,33 @@ #include "ignore.h" #include "buffer.h" -#define IDX_AS_PTR(I) (void *)((uint64_t)(I)) -#define PTR_AS_IDX(P) (unsigned int)((uint64_t)(P)) +typedef struct tree_iterator_frame tree_iterator_frame; +struct tree_iterator_frame { + tree_iterator_frame *next; + git_tree *tree; + unsigned int index; +}; typedef struct { - git_iterator cb; + git_iterator base; git_repository *repo; - git_vector tree_stack; - git_vector idx_stack; + tree_iterator_frame *stack; git_index_entry entry; git_buf path; -} git_iterator_tree; +} tree_iterator; -static const git_tree_entry *git_iterator__tree_entry(git_iterator_tree *ti) +static const git_tree_entry *tree_iterator__tree_entry(tree_iterator *ti) { - git_tree *tree; - unsigned int tree_idx; - - if ((tree = git_vector_last(&ti->tree_stack)) == NULL) - return NULL; - - tree_idx = PTR_AS_IDX(git_vector_last(&ti->idx_stack)); - return git_tree_entry_byindex(tree, tree_idx); + return (ti->stack == NULL) ?

Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure.

The relevant code is in `blob.c`: the blob write function has been split into smaller functions. - Directly write a file to the ODB in streaming mode - Directly write a symlink to the ODB in direct mode - Apply a filter, and write a file to the ODB in direct mode When trying to write a file, we first call `git_filter__load_for_file`, which populates a filters array with the required filters based on the filename.

However, if these macros are implemented as a simple rename for the `git_attr__true` pointer, they will always be used with the `==` operator, and hence we cannot really change the implementation to any other way that doesn't imply using special pointer values and comparing them! We need to do the same thing that core Git does, which is using a function macro. With `GIT_ATTR_TRUE(attr)`, we can change internally the way that these values are stored to anything we want. This commit does that, and rewrites a large chunk of the attributes test suite to remove duplicated code for expected attributes, and to properly test the function macro behavior instead of comparing pointers. --- include/git2/attr.h | 10 +- src/attr_file.c | 6 +- src/crlf.c | 8 +- tests-clar/attr/file.c | 46 ++++---- tests-clar/attr/lookup.c | 277 +++++++++++++++++++++++------------------------ tests-clar/attr/repo.c | 161 ++++++++++++--------------- 6 files changed, 240 insertions(+), 268 deletions(-) diff --git a/include/git2/attr.h b/include/git2/attr.h index 7e8bb9fe8..81d1e517b 100644 --- a/include/git2/attr.h +++ b/include/git2/attr.h @@ -19,12 +19,12 @@ */ GIT_BEGIN_DECL -#define GIT_ATTR_TRUE git_attr__true -#define GIT_ATTR_FALSE git_attr__false -#define GIT_ATTR_UNSPECIFIED NULL +#define GIT_ATTR_TRUE(attr) ((attr) == git_attr__true) +#define GIT_ATTR_FALSE(attr) ((attr) == git_attr__false) +#define GIT_ATTR_UNSPECIFIED(attr) ((attr) == NULL) -GIT_EXTERN(const char *)git_attr__true; -GIT_EXTERN(const char *)git_attr__false; +GIT_EXTERN(const char *) git_attr__true; +GIT_EXTERN(const char *) git_attr__false; /** diff --git a/src/attr_file.c b/src/attr_file.c index a1b69a5bb..3783b5ef3 100644 --- a/src/attr_file.c +++ b/src/attr_file.c @@ -458,12 +458,12 @@ int git_attr_assignment__parse( } assign->name_hash = 5381; -

This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options. --- examples/diff.c | 43 +- include/git2/diff.h | 101 ++- include/git2/oid.h | 5 + include/git2/status.h | 2 +- src/diff.c | 1347 +++++++++++---------------------------- src/diff.h | 10 +- src/diff_output.c | 722 +++++++++++++++++++++ src/fileops.c | 13 +- src/fileops.h | 17 + src/iterator.c | 97 +-- src/iterator.h | 6 + src/oid.c | 10 + src/path.c | 43 ++ src/path.h | 22 + src/posix.h | 2 + src/status.c | 2 +- src/unix/posix.h | 1 - src/vector.c | 10 + src/vector.h | 6 + src/win32/dir.c | 12 +- src/win32/dir.h | 6 +- src/xdiff/xdiff.h | 4 +- tests-clar/clar_libgit2.h | 5 +- tests-clar/diff/diff_helpers.c | 14 +- tests-clar/diff/diff_helpers.h | 2 + tests-clar/diff/iterator.c | 4 +- tests-clar/diff/tree.c | 46 +- tests-clar/diff/workdir.c | 230 +++++++ tests-clar/status/status_data.h | 2 +- tests-clar/status/worktree.c | 2 +- tests/t18-status.c | 6 +- 31 files changed, 1705 insertions(+), 1087 deletions(-) create mode 100644 src/diff_output.c create mode 100644 tests-clar/diff/workdir.c diff --git a/examples/diff.c b/examples/diff.c index 5eb0f3179..f80f7029c 100644 --- a/examples/diff.c +++ b/examples/diff.c @@ -116,7 +116,7 @@ void usage(const char *message, const char *arg) fprintf(stderr, "%s: %s\n", message, arg);

This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing *count++ but meant to do (*count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file. --- src/attr.c | 6 ++-- src/cc-compat.h | 3 +- src/config_file.c | 3 +- src/diff.c | 2 +- src/diff_output.c | 12 ++++---- src/hashtable.h | 28 +++++++++--------- src/odb_pack.c | 4 +-- src/pkt.c | 6 ++-- src/refs.c | 29 +++++++++---------- src/remote.c | 4 +-- src/revwalk.c | 6 ++-- src/transport.c | 4 +-- src/transports/local.c | 6 ++-- src/win32/posix.h | 10 +++---- src/win32/pthread.c | 8 +++--- tests-clar/attr/repo.c | 8 +++--- tests-clar/clar_helpers.c | 49 ++++++++++++++++++++++++++++++++ tests-clar/clar_libgit2.h | 5 ++++ tests-clar/config/multivar.c | 8 ++++-- tests-clar/core/dirent.c | 6 ++-- tests-clar/diff/blob.c | 9 ++---- tests-clar/diff/index.c | 8 ++---- tests-clar/diff/iterator.c | 50 ++++++--------------------------- tests-clar/diff/tree.c | 9 ++---- tests-clar/diff/workdir.c | 8 ++---- tests-clar/status/ignore.c | 13 ++------- tests-clar/status/worktree.c | 67 ++++++++++++++++---------------------------- tests/t00-core.c | 6 ++-- tests/t07-hashtable.c | 5 +--- tests/t18-status.c | 8 +++--- tests/test_main.c | 6 ++-- 31 files changed, 181 insertions(+), 215 deletions(-) diff --git a/src/attr.c b/src/attr.c index a7c65f94c..603498df2 100644 --- a/src/attr.c +++ b/src/attr.c @@ -408,10 +408,9 @@ void git_attr_cache_flush( return;

It allocates a new error object and stores it in the passed error pointer. It has no return value. The arguments for `giterr_set` are as follows: + + - `git_error **error_ptr`: the pointer where the error will be created. + - `int error_class`: the class for the error. This is **not** an error code: this is an speficic enum that specifies the error family. The point is to map these families 1-1 with Exception types on higher level languages (e.g. GitRepositoryException) + - `const char *error_str, ...`: the error string, with optional formatting arguments + +- `void giterr_free(git_error *)`: takes an error and frees it. This function is available in the external API. + +- `void giterr_clear(git_error **)`: clears an error previously set in an error pointer, setting it to NULL and calling `giterr_free` on it. + +- `void giterr_propagate(git_error **, git_error *)`: moves an error to a given error pointer, handling the case when the error pointer is NULL (in that case the error gets freed, because it cannot be propagated). + +The new error code return values +-------------------------------- + +We are doing this the POSIX way: one error code for each "expected failure", and a generic error code for all the critical failures. + +For instance: A reference lookup can have an expected failure (which is when the reference cannot be found), and a critical failure (which could be any of a long list of things that could go wrong, such as the refs packfile being corrupted, a loose ref being written with the wrong permissions, etc). We cannot have distinct error codes for every single error in the library, hence `git_reference_lookup` would return GIT_SUCCESS if the operation was successful, GIT_ENOTFOUND when the reference doesn't exist, and GIT_ERROR when an error happens -- **the error is then detailed in the `git_error` parameter**. + +Please be smart when returning error codes. Functions have max two "expected errors", and in most cases only one. + +Writing error messages +---------------------- + +Here are some guidelines when writing error messages: + +- Use proper English, and an impersonal or past tenses: *The given path does not exist*, *Failed to lookup object in ODB* + +- Use short, direct and objective messages. **One line, max**. libgit2 is a low level library: think that all the messages reported will be thrown as Ruby or Python exceptions. Think how long are common exception messages in those languages. + +- **Do not add redundant information to the error message**, specially information that can be infered from the context. + + E.g. in `git_repository_open`, do not report a message like "Failed to open repository: path not found". Somebody is + calling that function. If it fails, he already knows that the repository failed to open! + +General guidelines for error reporting +-------------------------------------- + +- We never handle programming errors with these functions. Programming errors are `assert`ed, and when their source is internal, fixed as soon as possible. This is C, people. + + Example of programming errors that would **not** be handled: passing NULL to a function that expects a valid pointer; passing a `git_tree` to a function that expects a `git_commit`. All these cases need to be identified with `assert` and fixed asap. + + Example of a runtime error: failing to parse a `git_tree` because it contains invalid data. Failing to open a file because it doesn't exist on disk. These errors would be handled, and a `git_error` would be set. + +- The `git_error **` argument is always the last in the signature of all API calls. No exceptions. + +- When the programmer (or us, internally) doesn't need error handling, he can pass `NULL` to the `git_error **` param. This means that the errors won't be *reported*, but obviously they still will be handled (i.e. the failing function will interrupt and return cleanly). This is transparently handled by `giterr_set` + +- `git_error *` **must be initialized to `NULL` before passing its value to a function!!** + + ~~~c + git_error *err; + git_error *good_error = NULL; + + git_foo_func(arg1, arg2, &error); // invalid: `error` is not initialized + git_foo_func2(arg1, arg2, &good_error); // OK! + git_foo_func3(arg1, arg2, NULL); // OK! But no error reporting! + ~~~ + +- Piling up errors is an error! Don't do this! Errors must always be free'd when a function returns. + + ~~~c + git_error *error = NULL; + + git_foo_func1(arg1, &error); + git_foo_func2(arg2, &error); // WRONG! What if func1 failed? `error` would leak! + ~~~ + +- Likewise: do not rethrow errors internally! + + ~~~c + int git_commit_create(..., git_error **error) + { + if (git_reference_exists("HEAD", error) < 0) { + /* HEAD does not exist; create it so we can commit... */ + if (git_reference_create("HEAD", error) < 0) { + /* error could be rethrown */ + } + } + +- Remember that errors are now allocated, and hence they need to be free'd after they've been used. Failure to do so internally (e.g. in the already seen examples of error piling) will be reported by Valgrind, so we can easily find where are we rethrowing errors. + +- Remember that any function that fails **will set an error object**, and that object will be freed. -- cgit v1.2.3 From 60bc2d20c40e37e92e4e15479ac4dccbde069bec Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Vicent=20Mart=C3=AD?= Date: Tue, 14 Feb 2012 21:23:11 +0100 Subject: error-handling: Add new routines Obviously all the old throw routines are still in place, so we can gradually port over. --- include/git2/errors.h | 15 +++++++++ src/errors.c | 64 +++++++++++++++++++++++++++++++++++++++ src/win32/posix_w32.c | 8 +++-- tests-clar/object/tree/frompath.c | 2 +- 4 files changed, 86 insertions(+), 3 deletions(-) diff --git a/include/git2/errors.h b/include/git2/errors.h index f617986e1..54da869b4 100644 --- a/include/git2/errors.h +++ b/include/git2/errors.h @@ -113,8 +113,23 @@ typedef enum { /** The buffer is too short to satisfy the request */ GIT_ESHORTBUFFER = -32, +} git_error_t; + +typedef struct { + char *message; + int klass; } git_error; +typedef enum { + GITERR_NOMEMORY, + +} git_error_class; + +GIT_EXTERN(void) giterr_set(git_error **error_out, int error_class, const char *string, ...); +GIT_EXTERN(void) giterr_set_oom(git_error **error); +GIT_EXTERN(void) giterr_free(git_error *error); +GIT_EXTERN(void) giterr_clear(git_error **error); + /** * Return a detailed error string with the latest error * that occurred in the library. diff --git a/src/errors.c b/src/errors.c index 58e0976f2..0105c2538 100644 --- a/src/errors.c +++ b/src/errors.c @@ -6,6 +6,7 @@ */ #include "common.h" #include "global.h" +#include "posix.h" #include static struct { @@ -102,3 +103,66 @@ void git_clearerror(void) char *last_error = GIT_GLOBAL->error.last; last_error[0] = '\0'; } + +/******************************************** + * New error handling + ********************************************/ + +void giterr_set(git_error **error_out, int error_class, const char *string, ...) +{ + char error_str[1024]; + va_list arglist; + git_error *error; + + if (error_out == NULL) + return; + + error = git__malloc(sizeof(git_error)); + if (!error) { + giterr_set_oom(error_out); + return; + } + + va_start(arglist, string); + p_vsnprintf(error_str, sizeof(error_str), string, arglist); + va_end(arglist); + + error->message = git__strdup(error_str); + error->klass = error_class; + + if (error->message == NULL) { + free(error); + giterr_set_oom(error_out); + return; + } + + *error_out = error; +} + +static git_error g_git_oom_error = { + "Out of memory", + GITERR_NOMEMORY +}; + +void giterr_set_oom(git_error **error) +{ + if (error != NULL) + *error = &g_git_oom_error; +} + +void giterr_free(git_error *error) +{ + if (error == NULL || error == &g_git_oom_error) + return; + + free(error->message); + free(error); +} + +void giterr_clear(git_error **error) +{ + if (error != NULL) { + giterr_free(*error); + *error = NULL; + } +} diff --git a/src/win32/posix_w32.c b/src/win32/posix_w32.c index 91585aeae..8e70719f9 100644 --- a/src/win32/posix_w32.c +++ b/src/win32/posix_w32.c @@ -341,8 +341,12 @@ done: int p_vsnprintf(char *buffer, size_t count, const char *format, va_list argptr) { #ifdef _MSC_VER - int len = _vsnprintf(buffer, count, format, argptr); - return (len < 0) ? _vscprintf(format, argptr) : len; + int len; + + if (count == 0 || (len = _vsnprintf(buffer, count, format, argptr)) < 0) + return p_vscprintf(format, argptr); + + return len; #else /* MinGW */ return vsnprintf(buffer, count, format, argptr); #endif diff --git a/tests-clar/object/tree/frompath.c b/tests-clar/object/tree/frompath.c index 3857d42a8..523a0b99e 100644 --- a/tests-clar/object/tree/frompath.c +++ b/tests-clar/object/tree/frompath.c @@ -24,7 +24,7 @@ void test_object_tree_frompath__cleanup(void) cl_fixture_cleanup("testrepo.git"); } -static void assert_tree_from_path(git_tree *root, const char *path, git_error expected_result, const char *expected_raw_oid) +static void assert_tree_from_path(git_tree *root, const char *path, int expected_result, const char *expected_raw_oid) { git_tree *containing_tree = NULL; -- cgit v1.2.3 From 45d387ac78bcf3167d69b736d0b322717bc492d4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Vicent=20Mart=C3=AD?= Date: Wed, 15 Feb 2012 16:54:17 +0100 Subject: refs: Error handling rework.

} if __name__ == '__main__': main() -- cgit v1.2.3 From 7c7ff7d11e2d22f7b9c7f8152f5c58dde37ac207 Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Mon, 19 Mar 2012 16:10:11 -0700 Subject: Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class. --- include/git2/errors.h | 4 +- src/fileops.c | 4 +- src/index.c | 317 +++++++++++++++++++++++--------------------------- src/index.h | 2 + src/iterator.c | 17 +-- src/oid.c | 64 +++++----- src/util.c | 26 +++-- tests-clar/core/oid.c | 8 +- 8 files changed, 212 insertions(+), 230 deletions(-) diff --git a/include/git2/errors.h b/include/git2/errors.h index 5a4e540e1..d71df59a2 100644 --- a/include/git2/errors.h +++ b/include/git2/errors.h @@ -123,12 +123,14 @@ typedef struct { typedef enum { GITERR_NOMEMORY, GITERR_OS, + GITERR_INVALID, GITERR_REFERENCE, GITERR_ZLIB, GITERR_REPOSITORY, GITERR_CONFIG, GITERR_REGEX, - GITERR_ODB + GITERR_ODB, + GITERR_INDEX } git_error_class;

This adds two new sets of tests, the issue_592 tests from @nulltoken's pull request #601 and some new tests for submodules. The submodule tests still have issues where the status is not reported correctly. That needs to be fixed before merge. --- include/git2/status.h | 3 +- tests-clar/status/worktree.c | 87 ++++++++++++++++++++- tests/resources/issue_592/.gitted/COMMIT_EDITMSG | 1 +

This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule. --- include/git2.h | 2 +- include/git2/submodule.h | 105 +++++++++++ src/config.c | 6 +- src/config.h | 2 + src/config_file.c | 3 + src/config_file.h | 31 ++++ src/iterator.c | 30 +++- src/repository.c | 1 + src/repository.h | 6 + src/submodule.c | 384 +++++++++++++++++++++++++++++++++++++++++ tests-clar/status/submodules.c | 16 +- 11 files changed, 573 insertions(+), 13 deletions(-) create mode 100644 include/git2/submodule.h create mode 100644 src/config_file.h create mode 100644 src/submodule.c diff --git a/include/git2.h b/include/git2.h index 1711ff8be..7d053c4af 100644 --- a/include/git2.h +++ b/include/git2.h @@ -40,7 +40,7 @@ #include "git2/net.h" #include "git2/status.h" #include "git2/indexer.h" - +#include "git2/submodule.h" #include "git2/notes.h" #endif diff --git a/include/git2/submodule.h b/include/git2/submodule.h new file mode 100644 index 000000000..aee2260c1 --- /dev/null +++ b/include/git2/submodule.h @@ -0,0 +1,105 @@ +/* + * Copyright (C) 2012 the libgit2 contributors + * + * This file is part of libgit2, distributed under the GNU GPL v2 with + * a Linking Exception.

The existing `git_repository_open` and `git_repository_discover` are reimplemented on top of it. We may want to change the default behavior of `git_repository_open` but this commit does not do that. Improve support for "gitdir" files where the work dir is separate from the repo and support for the "separate-git-dir" config. Also, add support for opening repos created with `git-new-workdir` script (although I have only confirmed that they can be opened, not that all functions work correctly). There are also a few minor changes that came up: - Fix `git_path_prettify` to allow in-place prettifying. - Fix `git_path_root` to support backslashes on Win32. This fix should help many repo open/discover scenarios - it is the one function called when opening before prettifying the path. - Tweak `git_config_get_string` to set the "out" pointer to NULL if the config value is not found. Allows some other cleanup. - Fix a couple places that should have been calling `git_repository_config__weakptr` and were not. - Fix `cl_git_sandbox_init` clar helper to support bare repos. --- include/git2/repository.h | 14 ++ src/attr.c | 22 +- src/config.c | 31 +-- src/diff.c | 3 +- src/errors.c | 6 +- src/path.c | 25 +-- src/repository.c | 537 ++++++++++++++++++++++------------------------ tests-clar/clar_helpers.c | 23 +- tests-clar/clar_libgit2.h | 2 + tests-clar/repo/open.c | 250 ++++++++++++++++++++- 10 files changed, 573 insertions(+), 340 deletions(-) diff --git a/include/git2/repository.h b/include/git2/repository.h index 34dd90444..d760c23b7 100644 --- a/include/git2/repository.h +++ b/include/git2/repository.h @@ -70,6 +70,20 @@ GIT_EXTERN(int) git_repository_discover( int across_fs, const char *ceiling_dirs);

} -- cgit v1.2.3 From f201d613a80f7ad6f54d90eb7a7a0d8b8c72676b Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Fri, 13 Apr 2012 10:33:14 -0700 Subject: Add git_reference_lookup_oid and lookup_resolved Adds a new public reference function `git_reference_lookup_oid` that directly resolved a reference name to an OID without returning the intermediate `git_reference` object (hence, no free needed). Internally, this adds a `git_reference_lookup_resolved` function that combines looking up and resolving a reference. This allows us to be more efficient with memory reallocation. The existing `git_reference_lookup` and `git_reference_resolve` are reimplmented on top of the new utility and a few places in the code are changed to use one of the two new functions. --- include/git2/refs.h | 19 +++++++ src/refs.c | 139 ++++++++++++++++++++++++++++++----------------- src/refs.h | 23 ++++++++ src/repository.c | 19 +------ src/revwalk.c | 15 +---- src/status.c | 29 +++------- src/transports/local.c | 27 +++------ tests-clar/refs/lookup.c | 42 ++++++++++++++ 8 files changed, 192 insertions(+), 121 deletions(-) create mode 100644 tests-clar/refs/lookup.c diff --git a/include/git2/refs.h b/include/git2/refs.h index 5395ded4b..6f2ac3ce9 100644 --- a/include/git2/refs.h +++ b/include/git2/refs.h @@ -32,6 +32,16 @@ GIT_BEGIN_DECL */ GIT_EXTERN(int) git_reference_lookup(git_reference **reference_out, git_repository *repo, const char *name); +/** + * Lookup a reference by name and resolve immediately to OID. + * + * @param oid Pointer to oid to be filled in + * @param repo The repository in which to look up the reference + * @param name The long name for the reference + * @return 0 on success, -1 if name could not be resolved + */ +GIT_EXTERN(int) git_reference_lookup_oid(git_oid *out, git_repository *repo, const char *name); + /** * Create a new symbolic reference. * @@ -304,6 +314,15 @@ GIT_EXTERN(int) git_reference_reload(git_reference *ref); */ GIT_EXTERN(void) git_reference_free(git_reference *ref); +/** + * Compare two references. + * + * @param ref1 The first git_reference + * @param ref2 The second git_reference + * @return GIT_SUCCESS if the same, else a stable but meaningless ordering. + */ +GIT_EXTERN(int) git_reference_cmp(git_reference *ref1, git_reference *ref2); + /** @} */ GIT_END_DECL #endif diff --git a/src/refs.c b/src/refs.c index fb23a0ef8..90cb920ee 100644 --- a/src/refs.c +++ b/src/refs.c @@ -15,7 +15,8 @@ #include #include -#define MAX_NESTING_LEVEL 5 +#define DEFAULT_NESTING_LEVEL 5 +#define MAX_NESTING_LEVEL 10 enum { GIT_PACKREF_HAS_PEEL = 1, @@ -1057,24 +1058,80 @@ int git_reference_delete(git_reference *ref) int git_reference_lookup(git_reference **ref_out, git_repository *repo, const char *name) { - char normalized_name[GIT_REFNAME_MAX]; - git_reference *ref = NULL; - int result; + return git_reference_lookup_resolved(ref_out, repo, name, 0); +} + +int git_reference_lookup_oid( + git_oid *out, git_repository *repo, const char *name) +{ + int error; + git_reference *ref; + + if ((error = git_reference_lookup_resolved(&ref, repo, name, -1)) < 0) + return error; + + git_oid_cpy(out, git_reference_oid(ref)); + git_reference_free(ref); + return 0; +} + +int git_reference_lookup_resolved( + git_reference **ref_out, + git_repository *repo, + const char *name, + int max_nesting) +{ + git_reference *scan; + int result, nesting; assert(ref_out && repo && name); + *ref_out = NULL; - if (normalize_name(normalized_name, sizeof(normalized_name), name, 0) < 0) - return -1; + if (max_nesting > MAX_NESTING_LEVEL) + max_nesting = MAX_NESTING_LEVEL; + else if (max_nesting < 0) + max_nesting = DEFAULT_NESTING_LEVEL; - if (reference_alloc(&ref, repo, normalized_name) < 0) - return -1; + scan = git__calloc(1, sizeof(git_reference)); + GITERR_CHECK_ALLOC(scan); - result = reference_lookup(ref); - if (result == 0) - *ref_out = ref; + scan->name = git__calloc(GIT_REFNAME_MAX + 1, sizeof(char)); + GITERR_CHECK_ALLOC(scan->name); - return result; + if ((result = normalize_name(scan->name, GIT_REFNAME_MAX, name, 0)) < 0) { + git_reference_free(scan); + return result; + } + + scan->target.symbolic = git__strdup(scan->name); + GITERR_CHECK_ALLOC(scan->target.symbolic); + + scan->owner = repo; + scan->flags = GIT_REF_SYMBOLIC; + + for (nesting = max_nesting; + nesting >= 0 && (scan->flags & GIT_REF_SYMBOLIC) != 0; + nesting--) + { + if (nesting != max_nesting) + strncpy(scan->name, scan->target.symbolic, GIT_REFNAME_MAX); + + scan->mtime = 0; + + if ((result = reference_lookup(scan)) < 0) + return result; /* lookup git_reference_free on scan already */ + } + + if ((scan->flags & GIT_REF_OID) == 0 && max_nesting != 0) { + giterr_set(GITERR_REFERENCE, + "Cannot resolve reference (>%u levels deep)", max_nesting); + git_reference_free(scan); + return -1; + } + + *ref_out = scan; + return 0; } /** @@ -1381,47 +1438,10 @@ rollback: int git_reference_resolve(git_reference **ref_out, git_reference *ref) { - int result, i = 0; - git_repository *repo; - - assert(ref); - - *ref_out = NULL; - repo = ref->owner; - - /* If the reference is already resolved, we need to return a - * copy.

Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest. --- src/blob.c | 4 +- src/buffer.c | 2 +- src/config_file.c | 10 +- src/errors.c | 2 +- src/filter.c | 2 +- src/global.c | 6 +- src/odb.c | 2 +- src/pool.c | 249 +++++++++++++++++++++++++++++++++++++++++++++++++ src/pool.h | 108 +++++++++++++++++++++ src/refs.c | 2 +- src/remote.c | 2 +- src/repository.c | 2 +- tests-clar/core/pool.c | 85 +++++++++++++++++ 13 files changed, 459 insertions(+), 17 deletions(-) create mode 100644 src/pool.c create mode 100644 src/pool.h create mode 100644 tests-clar/core/pool.c diff --git a/src/blob.c b/src/blob.c index f553de888..36571c70a 100644 --- a/src/blob.c +++ b/src/blob.c @@ -139,12 +139,12 @@ static int write_symlink( read_len = p_readlink(path, link_data, link_size); if (read_len != (ssize_t)link_size) { giterr_set(GITERR_OS, "Failed to create blob.

For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now. --- src/attr.c | 85 +++++++++++++++++++++++------------- src/attr.h | 8 +++- src/attr_file.c | 4 +- src/config.c | 1 - src/config_file.c | 95 +++++++++++++++++++++++++--------------- src/khash.h | 100 +++++++++++++++++++++++++++++++++--------- src/khash_oid.h | 42 ++++++++++++++++++ src/khash_str.h | 54 +++++++++++++++++++++++ src/refs.c | 72 ++++++++++++++++++------------ src/refs.h | 4 +- src/repository.h | 4 +- src/revwalk.c | 38 ++++++++-------- src/submodule.c | 128 +++++++++++++++++++++++++++++------------------------- 13 files changed, 433 insertions(+), 202 deletions(-) create mode 100644 src/khash_oid.h create mode 100644 src/khash_str.h diff --git a/src/attr.c b/src/attr.c index f5d50bb42..1d7f3aa22 100644 --- a/src/attr.c +++ b/src/attr.c @@ -3,6 +3,8 @@ #include "config.h" #include +GIT_KHASH_STR__IMPLEMENTATION;

This adds a parameter to all of the gitattributes related functions that allows user control of attribute reading behavior (i.e. prefer workdir, prefer index, only use index). This fix also covers allowing us to check attributes (and hence do diff and status) on bare repositories. This was a somewhat larger change that I hoped because it had to change the cache key used for gitattributes files. --- AUTHORS | 1 + include/git2/attr.h | 166 +++++++++++- src/attr.c | 286 +++++++++++++++------ src/attr.h | 26 +- src/attr_file.c | 90 ++++--- src/attr_file.h | 21 +- src/crlf.c | 3 +- src/diff_output.c | 2 +- src/ignore.c | 69 ++--- src/ignore.h | 5 +- src/object.c | 39 +++ src/repository.c | 20 ++ src/repository.h | 4 + src/status.c | 44 +--- tests-clar/attr/file.c | 25 +- tests-clar/attr/flags.c | 108 ++++++++ tests-clar/attr/lookup.c | 22 +- tests-clar/attr/repo.c | 39 +-- tests-clar/diff/tree.c | 66 ++++- tests-clar/resources/attr_index/.gitted/HEAD | 1 + tests-clar/resources/attr_index/.gitted/config | 6 + .../resources/attr_index/.gitted/description | 1 + tests-clar/resources/attr_index/.gitted/index | Bin 0 -> 520 bytes .../resources/attr_index/.gitted/info/exclude | 6 + tests-clar/resources/attr_index/.gitted/info/refs | 1 + tests-clar/resources/attr_index/.gitted/logs/HEAD | 4 + .../attr_index/.gitted/logs/refs/heads/master | 4 + .../cd/f17ea3fe625ef812f4dce7f423f4f299287505 | Bin 0 -> 61 bytes .../attr_index/.gitted/objects/info/packs | 2 + ...ck-4e6438607204ce78827e3885594b2c0bb4f13895.idx | Bin 0 -> 1492 bytes ...k-4e6438607204ce78827e3885594b2c0bb4f13895.pack | Bin 0 -> 1106 bytes .../resources/attr_index/.gitted/packed-refs | 2 + tests-clar/resources/attr_index/README.md | 1 + tests-clar/resources/attr_index/README.txt | 1 + tests-clar/resources/attr_index/gitattributes | 4 + .../resources/attr_index/sub/sub/.gitattributes | 3 + tests-clar/resources/attr_index/sub/sub/README.md | 1 + tests-clar/resources/attr_index/sub/sub/README.txt | 1 + tests-clar/status/ignore.c | 4 +- 39 files changed, 793 insertions(+), 285 deletions(-) create mode 100644 tests-clar/attr/flags.c create mode 100644 tests-clar/resources/attr_index/.gitted/HEAD create mode 100644 tests-clar/resources/attr_index/.gitted/config create mode 100644 tests-clar/resources/attr_index/.gitted/description create mode 100644 tests-clar/resources/attr_index/.gitted/index create mode 100644 tests-clar/resources/attr_index/.gitted/info/exclude create mode 100644 tests-clar/resources/attr_index/.gitted/info/refs create mode 100644 tests-clar/resources/attr_index/.gitted/logs/HEAD create mode 100644 tests-clar/resources/attr_index/.gitted/logs/refs/heads/master create mode 100644 tests-clar/resources/attr_index/.gitted/objects/cd/f17ea3fe625ef812f4dce7f423f4f299287505 create mode 100644 tests-clar/resources/attr_index/.gitted/objects/info/packs create mode 100644 tests-clar/resources/attr_index/.gitted/objects/pack/pack-4e6438607204ce78827e3885594b2c0bb4f13895.idx create mode 100644 tests-clar/resources/attr_index/.gitted/objects/pack/pack-4e6438607204ce78827e3885594b2c0bb4f13895.pack create mode 100644 tests-clar/resources/attr_index/.gitted/packed-refs create mode 100644 tests-clar/resources/attr_index/README.md create mode 100644 tests-clar/resources/attr_index/README.txt create mode 100644 tests-clar/resources/attr_index/gitattributes create mode 100644 tests-clar/resources/attr_index/sub/sub/.gitattributes create mode 100644 tests-clar/resources/attr_index/sub/sub/README.md create mode 100644 tests-clar/resources/attr_index/sub/sub/README.txt diff --git a/AUTHORS b/AUTHORS index 954f25964..03904ff55 100644 --- a/AUTHORS +++ b/AUTHORS @@ -43,6 +43,7 @@ Ramsay Jones Robert G.

-- cgit v1.2.3 From b4b96d56bf1d9f362441e5e650b023040a319e05 Mon Sep 17 00:00:00 2001 From: "Scott J. Goldman" Date: Sat, 5 May 2012 13:30:33 -0700 Subject: Fix gitno_connect() error handling on Windows gitno_connect() can return an error or socket, which is fine on most platforms where sockets are file descriptors (signed int), but on Windows, SOCKET is an unsigned type, which is problematic when we are trying to test if the socket was actually a negative error code. This fix seperates the error code and socket in gitno_connect(), and fixes the error handling in do_connect() functions to compensate. It appears that git_connect() and the git-transport do_connect() functions had bugs in the non-windows cases too (leaking sockets, and not properly reporting connection error, respectively) so I went ahead and fixed those too. --- src/netops.c | 14 +++++++------- src/netops.h | 2 +- src/transports/git.c | 10 ++++++---- src/transports/http.c | 9 +++++---- 4 files changed, 19 insertions(+), 16 deletions(-) diff --git a/src/netops.c b/src/netops.c index 4b307af45..e1ab2435b 100644 --- a/src/netops.c +++ b/src/netops.c @@ -74,12 +74,11 @@ void gitno_consume_n(gitno_buffer *buf, size_t cons) buf->offset -= cons; } -int gitno_connect(const char *host, const char *port) +int gitno_connect(const char *host, const char *port, GIT_SOCKET *s) { struct addrinfo *info, *p; struct addrinfo hints; int ret, error = GIT_SUCCESS; - GIT_SOCKET s; memset(&hints, 0x0, sizeof(struct addrinfo)); hints.ai_family = AF_UNSPEC; @@ -93,24 +92,25 @@ int gitno_connect(const char *host, const char *port) } for (p = info; p != NULL; p = p->ai_next) { - s = socket(p->ai_family, p->ai_socktype, p->ai_protocol); + *s = socket(p->ai_family, p->ai_socktype, p->ai_protocol); #ifdef GIT_WIN32 - if (s == INVALID_SOCKET) { + if (*s == INVALID_SOCKET) { #else - if (s < 0) { + if (*s < 0) { #endif error = GIT_EOSERR; goto cleanup; } - ret = connect(s, p->ai_addr, p->ai_addrlen); + ret = connect(*s, p->ai_addr, p->ai_addrlen); /* If we can't connect, try the next one */ if (ret < 0) { + close(*s); continue; } /* Return the socket */ - error = s; + error = GIT_SUCCESS; goto cleanup; } diff --git a/src/netops.h b/src/netops.h index 01ad9714f..cef39d923 100644 --- a/src/netops.h +++ b/src/netops.h @@ -25,7 +25,7 @@ int gitno_recv(gitno_buffer *buf); void gitno_consume(gitno_buffer *buf, const char *ptr); void gitno_consume_n(gitno_buffer *buf, size_t cons); -int gitno_connect(const char *host, const char *port); +int gitno_connect(const char *host, const char *port, GIT_SOCKET *s); int gitno_send(GIT_SOCKET s, const char *msg, size_t len, int flags); int gitno_close(GIT_SOCKET s); int gitno_send_chunk_size(int s, size_t len); diff --git a/src/transports/git.c b/src/transports/git.c index 88e7e8160..b0acc7e62 100644 --- a/src/transports/git.c +++ b/src/transports/git.c @@ -106,10 +106,12 @@ static int do_connect(transport_git *t, const char *url) if (error < GIT_SUCCESS) return error; - s = gitno_connect(host, port); - connected = 1; - error = send_request(s, NULL, url); - t->socket = s; + error = gitno_connect(host, port, &s); + if (error == GIT_SUCCESS) { + connected = 1; + error = send_request(s, NULL, url); + t->socket = s; + } git__free(host); git__free(port); diff --git a/src/transports/http.c b/src/transports/http.c index 2842d08fd..323b56105 100644 --- a/src/transports/http.c +++ b/src/transports/http.c @@ -82,14 +82,15 @@ static int gen_request(git_buf *buf, const char *url, const char *host, const ch static int do_connect(transport_http *t, const char *host, const char *port) { - GIT_SOCKET s = -1; + int error = GIT_SUCCESS; + GIT_SOCKET s; if (t->parent.connected && http_should_keep_alive(&t->parser)) return GIT_SUCCESS; - s = gitno_connect(host, port); - if (s < GIT_SUCCESS) { - return git__rethrow(s, "Failed to connect to host"); + error = gitno_connect(host, port, &s); + if (error != GIT_SUCCESS) { + return git__rethrow(error, "Failed to connect to host"); } t->socket = s; t->parent.connected = 1; -- cgit v1.2.3 From b47e0a71718823338686b49614f7c7536265d3a8 Mon Sep 17 00:00:00 2001 From: "Scott J.

For cached files from the index, it checks the SHA of the file instead. This should reduce the need to ever call `git_attr_cache_flush()` in most situations.

MSVC will disallow itself from optimizing these symbols out and reference them in the PE's Exports-Table. Further, a static link library will be generated. This library contains the symbols which are exported via the declsepc above. The __declspec(dllexport) becomes part of the symbol-signature (like parameter types in C++ are 'mangled' into the symbol name, the export specifier is mingled with the name) - specify __declspec(dllimport) when using the library. This again mingles the declspec into the name and declares the function / variable with external linkage. cmake automatically adds -Dgit2_EXPORTS to the compiler arguments when compiling the libgit2 project.

This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good. --- include/git2/status.h | 31 +++-- src/attr_file.c | 2 +- src/buffer.c | 27 ++++ src/buffer.h | 2 + src/diff.c | 47 +++++-- src/index.c | 9 ++ src/index.h | 2 + src/iterator.c | 303 ++++++++++++++++++++++++++++++++--------- src/iterator.h | 54 +++++++- src/status.c | 252 ++++++---------------------------- src/tree.c | 27 ++++ src/tree.h | 10 ++ src/util.h | 5 + src/vector.c | 23 ++-- src/vector.h | 17 ++- tests-clar/core/buffer.c | 50 +++++++ tests-clar/diff/iterator.c | 222 ++++++++++++++++++++++++++++-- tests-clar/status/submodules.c | 7 + 18 files changed, 761 insertions(+), 329 deletions(-) diff --git a/include/git2/status.h b/include/git2/status.h index 0aff56a65..0130b4011 100644 --- a/include/git2/status.h +++ b/include/git2/status.h @@ -36,15 +36,18 @@ GIT_BEGIN_DECL /** * Gather file statuses and run a callback for each one. * - * The callback is passed the path of the file, the status and the data pointer - * passed to this function.

To make that a little clearer, if you have a .gitignore with: ignore/ And then have the following files: ignore/dir/tracked <-- actually a tracked file ignore/dir/untracked <-- should be ignored Then we would show the tracked file as being removed (because when we got the to contained item "dir/" inside the ignored directory, we decided it was safe to skip -- bzzt, wrong!). This update is much more careful about checking that we are not skipping over any prefix of a tracked item, regardless of whether it is ignored or not. As documented in diff.c, this commit does create behavior that still differs from core git with regards to the handling of untracked files contained inside ignored directories. With libgit2, those files will just not show up in status or diff. With core git, those files don't show up in status or diff either *unless* they are explicitly ignored by a .gitignore pattern in which case they show up as ignored files. Needless to say, this is a local behavior difference only, so it should not be important and (to me) the libgit2 behavior seems more consistent. --- src/diff.c | 60 +++++++++----- tests-clar/resources/issue_592b/.gitted/HEAD | 1 + tests-clar/resources/issue_592b/.gitted/config | 6 ++ .../resources/issue_592b/.gitted/description | 1 + .../issue_592b/.gitted/hooks/post-update.sample | 8 ++ tests-clar/resources/issue_592b/.gitted/index | Bin 0 -> 376 bytes .../resources/issue_592b/.gitted/info/exclude | 6 ++ tests-clar/resources/issue_592b/.gitted/logs/HEAD | 1 + .../issue_592b/.gitted/logs/refs/heads/master | 1 + .../3f/bf1852f72fd268e36457b13a18cdd9a4c9ea35 | 2 + .../6f/a891d3e578c83e1c03bdb9e0fdd8e6e934157f | Bin 0 -> 28 bytes .../80/07d41d5794e6ce4d4d2c97e370d5a9aa6d5213 | Bin 0 -> 24 bytes .../a6/5fb6583a7c425284142f285bc359a2d6565513 | Bin 0 -> 93 bytes .../ae/be7a55922c7097ef91ca3a7bc327a901d87c2c | Bin 0 -> 122 bytes .../b3/44b055867fcdc1f01eaa75056a43e868eb4fbc | Bin 0 -> 36 bytes .../f7/d75fbfad8b1d2e307ced287ea78aad403cdce3 | Bin 0 -> 57 bytes .../resources/issue_592b/.gitted/refs/heads/master | 1 + tests-clar/resources/issue_592b/gitignore | 1 + .../issue_592b/ignored/contained/ignored3.txt | 1 + .../issue_592b/ignored/contained/tracked3.txt | 1 + .../resources/issue_592b/ignored/ignored2.txt | 1 + .../resources/issue_592b/ignored/tracked2.txt | 1 + tests-clar/resources/issue_592b/ignored1.txt | 1 + tests-clar/resources/issue_592b/tracked1.txt | 1 + tests-clar/status/worktree.c | 90 +++++++++++++++++---- 25 files changed, 148 insertions(+), 36 deletions(-) create mode 100644 tests-clar/resources/issue_592b/.gitted/HEAD create mode 100644 tests-clar/resources/issue_592b/.gitted/config create mode 100644 tests-clar/resources/issue_592b/.gitted/description create mode 100755 tests-clar/resources/issue_592b/.gitted/hooks/post-update.sample create mode 100644 tests-clar/resources/issue_592b/.gitted/index create mode 100644 tests-clar/resources/issue_592b/.gitted/info/exclude create mode 100644 tests-clar/resources/issue_592b/.gitted/logs/HEAD create mode 100644 tests-clar/resources/issue_592b/.gitted/logs/refs/heads/master create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/3f/bf1852f72fd268e36457b13a18cdd9a4c9ea35 create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/6f/a891d3e578c83e1c03bdb9e0fdd8e6e934157f create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/80/07d41d5794e6ce4d4d2c97e370d5a9aa6d5213 create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/a6/5fb6583a7c425284142f285bc359a2d6565513 create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/ae/be7a55922c7097ef91ca3a7bc327a901d87c2c create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/b3/44b055867fcdc1f01eaa75056a43e868eb4fbc create mode 100644 tests-clar/resources/issue_592b/.gitted/objects/f7/d75fbfad8b1d2e307ced287ea78aad403cdce3 create mode 100644 tests-clar/resources/issue_592b/.gitted/refs/heads/master create mode 100644 tests-clar/resources/issue_592b/gitignore create mode 100644 tests-clar/resources/issue_592b/ignored/contained/ignored3.txt create mode 100644 tests-clar/resources/issue_592b/ignored/contained/tracked3.txt create mode 100644 tests-clar/resources/issue_592b/ignored/ignored2.txt create mode 100644 tests-clar/resources/issue_592b/ignored/tracked2.txt create mode 100644 tests-clar/resources/issue_592b/ignored1.txt create mode 100644 tests-clar/resources/issue_592b/tracked1.txt diff --git a/src/diff.c b/src/diff.c index c8670b53e..d5c0c8ba5 100644 --- a/src/diff.c +++ b/src/diff.c @@ -551,29 +551,27 @@ static int diff_from_iterators( * matched in old (and/or descend into directories as needed) */ else if (nitem && (!oitem || strcmp(oitem->path, nitem->path) > 0)) { - int is_ignored;

Highlights on this release include diff, branches, notes and submodules support. The new diff API is shiny and powerful. Check it out. Apologies, one more time, to all the early adopters for the breaking API changes. We've been iterating on the error handling for the library until we reached its current state, which we believe it's significantly more usable both for normal users and for developers of bindings to other languages. Also, we've renamed a few legacy calls to ensure that the whole external API uses a consistent naming scheme. As always, check the API docs for the full list of new API calls and backwards-incompatible changes. http://libgit2.github.com/libgit2/ Changelog of new features follows: Attributes: - Added function macros to check attribute values instead of having to manually compare them - Added support for choosing the attribute loading order (workdir files vs index) and to skip the systems' default `.gitattributes` - Fixed issues when fetching attribute data on bare repositories Blob: - Added support for creating blobs from any file on disk (not restricted to the repository's working directory) - Aded support for smudge filters when writing blobs to the ODB - So far only CRLF normalization is available Branches: - Added a high-level branch API: - git_branch_create - git_branch_delete - git_branch_list - git_branch_move Commit: - Commit messages are now filtered to match Git rules (stripping comments and adding proper whitespacing rules) Config: - Added support for setting and getting multivars - Added `git_config_get_mapped` to map the value of a config variable based on its defaults Diff: - Added full diff API: - tree to tree - index to tree - workdir to index - workdir to tree - blob to blob - Added helper functions to print the diffs as valid patchfiles Error handling: - New design for the error handling API, taking into consideration the requirements of dynamic languages Indexer: - Added streaming packfile indexer Merge: - Added support for finding the merge base between two commits Notes: - Full git-notes support: - git_note_read - git_note_message/git_note_oid - git_note_create - git_note_remove - git_note_free - git_note_foreach References: - Added `git_reference_name_to_oid` helper to resolve a reference to its final OID - Added `git_reference_cmp` to compare two references with a stable order Remotes: - Added support for writing and saving remotes - `git_remote_add` - `git_remote_save` - Setters for all the attributes of a remote - Switched remote download to the new streaming packfile indexer - Fixed fetch on HTTP and Git under Windows - Added `git_remote_supported_url` helper to check if a protocol can be accessed by the library - Added `git_remote_list` Repository: - Made `git_repository_open` smarter when finding the `.git` folder. - Added `git_repository_open_ext` with extra options when opening a repository Revwalk: - Added support for pushing/hiding several references through a glob - Added helper to push/hide the current HEAD to the walker - Added helper to push/hide a single reference to the walker Status: - Greatly improved Status implementation using the new `diff` code as a backend Submodules: - Added a partial submodules API to get information about a submodule and list all the submodules in a repository - git_submodule_foreach - git_submodule_lookup Tag: - Added `git_tag_peel` helper to peel a tag to its pointed object - Tag messages are now filtered to match Git rules (stripping comments and adding proper whitespacing rules) Tree: - Killed the old `git_tree_diff` API, which is replaced by the new diff code.
