Russell Belfer c2b67043 2012-04-25T15:20:28 Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
Russell Belfer 01fed0a8 2012-04-25T10:36:01 Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. 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.
Russell Belfer 2bc8fa02 2012-04-17T10:14:24 Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. 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.
Carlos Martín Nieto a7d19b97 2012-04-25T15:47:53 config: also allow escaping outside of a quoted string This limitation was a misparsing of the documentation.
Carlos Martín Nieto 2c1075d6 2012-03-16T12:52:49 config: parse quoted values Variable values may be quoted to include newlines, literal quotes and other characters. Add support for these and test it.

Russell Belfer bfc9ca59 2012-03-28T16:45:36 Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. 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.
Carlos Martín Nieto 54fef6eb 2012-03-09T20:38:32 config: write out section headers with subsections correctly write_section() mistakenly treated is input as the whole variable name instead of simply the section (and possibly subsection) and would confuse "section.subsection" as a section plus variable name and produce a wrong section header. Fix this and include a test for writing "section.subsection.var" and reading it from the file.
Vicent Martí dda708e7 2012-03-09T19:55:50 error-handling: On-disk config file backend Includes: - Proper error reporting when encountering syntax errors in a config file (file, line number, column). - Rewritten `config_write`, now with 99% less goto-spaghetti - Error state in `git_filebuf`: filebuf write functions no longer need to be checked for error returns. If any of the writes performed on a buffer fail, the last call to `git_filebuf_commit` or `git_filebuf_hash` will fail accordingly and set the appropiate error message. Baller!
Russell Belfer 854eccbb 2012-02-29T12:04:59 Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. 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.
Vicent Martí 13224ea4 2012-02-27T04:28:31 buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. 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. Hopefully this won't break anything.
Carlos Martín Nieto 0a43d7cb 2012-02-25T18:52:28 config: correctly deal with setting a multivar with regex where there are no matches We used to erroneously consider "^$" as a special case for appending a value to a multivar. This was a misunderstanding and we should always append a value if there are no existing values that match. While we're in the area, replace all the variables in-memory in one swoop and then replace them on disk so as to avoid matching a value we've just introduced.

Carlos Martín Nieto a9fe8ae0 2012-01-23T22:14:04 config: don't use 'section "subsection"' internal form on config_set This had been left over from a time when I believed what the git documentation had to say about case-sensitivity. The rest of the code doesn't recognize this form and we hadn't noticed because most tests don't try to get a recently-set variable but free and reload the configuration, causing the right format to be used.
Carlos Martín Nieto c1c399cf 2012-01-13T19:33:54 config: handle EOF properly In the main loop we peek to see what kind of line the next one is. If there are multiple newlines before the end of the file, the eof marker won't be set after we read the last line with data and we'll try to peek again. This peek will return LF (as it pretends that we have a newline at EOF so other function don't need any special handling). Fix cfg_getchar so it doesn't try to read past the last character in the file and config_parse so it considers LF as EOF on peek (as we're ignoring spaces) and sets the reader's EOF flag to exit the parsing loop.

Carlos Martín Nieto 80a665aa 2011-12-16T02:28:39 config: really delete variables Instead of just setting the value to NULL, which gives unwanted results when asking for that variable after deleting it, delete the variable from the list and re-write the file.
Carlos Martín Nieto 7b2b4adf 2011-12-16T01:39:28 Revert "config: Return ENOTFOUND when a variable was deleted" This would make us think that config variables like [core] something is missing.

Vicent Marti 9462c471 2011-11-25T08:16:26 repository: Change ownership semantics The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.

Oleg Andreev 9f861826 2011-10-27T16:45:44 Fixed crash in config parser when empty value is encountered. Example: key1 = value1 key2 = In this config the value will be a bad pointer which config object will attempt to free() causing a crash.
Brodie Rao 01ad7b3a 2011-09-06T15:48:45 *: correct and codify various file permissions The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".

These are abstractions on top of the original POSIX calls. There's a new file called `posix.c` that contains emulations/reimplementations of all the POSIX calls the library uses. These are prefixed with `p_`. There's a specific posix file for each platform (win32 and unix). All the path-related methods have been moved from `utils.c` to `path.c` and have their own prefix.
