Edward Thomson 619f61a8 2018-02-01T06:22:36 odb: error when we can't create object header Return an error to the caller when we can't create an object header for some reason (printf failure) instead of simply asserting.
Edward Thomson 09df354e 2018-02-01T16:52:43 odb_loose: HEADER_LEN -> MAX_HEADER_LEN `MAX_HEADER_LEN` is a more descriptive constant name.
Edward Thomson 624614b2 2017-12-19T00:43:49 odb_loose: validate length when checking for zlib content When checking to see if a file has zlib deflate content, make sure that we actually have read at least two bytes before examining the array.
Edward Thomson 1118ba3e 2017-12-18T23:08:40 odb_loose: `read_header` for packlike loose objects Support `read_header` for "packlike loose objects", which were a temporarily and uncommonly used format loose object format that encodes the header before the zlib deflate data. This will never actually be seen in the wild, but add support for it for completeness and (more importantly) because our corpus of test data has objects in this format, so it's easier to support it than to try to special case it.
Edward Thomson 4c7a16b7 2017-12-18T15:56:21 odb_loose: read_header should use zstream Make `read_header` use the common zstream implementation. Remove the now unnecessary zlib wrapper in odb_loose.
Edward Thomson 80dc3946 2017-12-17T16:26:48 odb_loose: packlike loose objects use `git_zstream` Refactor packlike loose object reads to use `git_zstream` for simplification.
Edward Thomson 7cb5bae7 2017-12-17T11:55:18 odb: loose object streaming for packlike loose objects A "packlike" loose object was a briefly lived loose object format where the type and size were encoded in uncompressed space at the beginning of the file, followed by the compressed object contents. Handle these in a streaming manner as well.
Edward Thomson b61846f2 2017-12-17T02:14:29 odb: introduce streaming loose object reader Provide a streaming loose object reader.
Edward Thomson c74e9271 2017-12-16T22:10:11 odb_loose: stream -> writestream There are two streaming functions; one for reading, one for writing. Disambiguate function names between `stream` and `writestream` to make allowances for a read stream.
Edward Thomson 3e6533ba 2017-12-10T17:25:00 odb_loose: reject objects that cannot fit in memory Check the size of objects being read from the loose odb backend and reject those that would not fit in memory with an error message that reflects the actual problem, instead of error'ing later with an unintuitive error message regarding truncation or invalid hashes.
Edward Thomson ddefea75 2017-11-30T15:55:59 odb: support large loose objects zlib will only inflate/deflate an `int`s worth of data at a time. We need to loop through large files in order to ensure that we inflate the entire file, not just an `int`s worth of data. Thankfully, we already have this loop in our `git_zstream` layer. Handle large objects using the `git_zstream`.
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 6c23704d 2017-06-08T21:40:18 settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.
Edward Thomson 1dc89aab 2017-05-01T21:34:21 object validation: free some memleaks
Edward Thomson 2a5ad7d0 2017-02-17T16:42:40 fsync: call it "synchronous" object writing Rename `GIT_OPT_ENABLE_SYNCHRONIZED_OBJECT_CREATION` -> `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION`.
Edward Thomson 6d3ad7e0 2016-12-13T10:58:43 Add `ENABLE_SYNCHRONIZED_OBJECT_CREATION` option Allow users to enable `SYNCHRONIZED_OBJECT_CREATION` with a setting.
Edward Thomson fc27fe21 2016-12-13T10:35:05 odb_loose: actually honor the fsync option We've had an fsync option for a long time, but it was "ignored". Stop ignoring it.
Edward Thomson 909d5494 2016-12-29T12:25:15 giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
Edward Thomson 27051d4e 2016-07-22T13:34:19 odb: only freshen pack files every 2 seconds Since writing multiple objects may all already exist in a single packfile, avoid freshening that packfile repeatedly in a tight loop. Instead, only freshen pack files every 2 seconds.
Edward Thomson 8f09a98e 2016-07-14T16:23:24 odb: freshen existing objects when writing When writing an object, we calculate its OID and see if it exists in the object database. If it does, we need to freshen the file that contains it.
Edward Thomson 6a2d2f8a 2015-06-17T06:42:20 delta: move delta application to delta.c Move the delta application functions into `delta.c`, next to the similar delta creation functions. Make the `git__delta_apply` functions adhere to other naming and parameter style within the library.
Patrick Steinhardt 7f407710 2016-05-02T16:24:14 odb_loose: fix undefined behavior when computing size An object's size is computed by reading the object header's size field until the most significant bit is not set anymore. To get the total size, we increase the shift on each iteration and add the shifted value to the total size. We read the current value into a variable of type `unsigned char`, from which we then take all bits except the most significant bit and shift the result. We will end up with a maximum shift of 60, but this exceeds the width of the value's type, resulting in undefined behavior. Fix the issue by instead reading the values into a variable of type `unsigned long`, which matches the required width. This is equivalent to git.git, which uses an `unsigned long` as well.
Edward Thomson e10144ae 2016-03-04T01:18:30 odb: improved not found error messages When looking up an abbreviated oid, show the actual (abbreviated) oid the caller passed instead of a full (but ambiguously truncated) oid.
Edward Thomson ac2fba0e 2015-09-16T15:07:27 git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.
Carlos Martín Nieto 77b339f7 2015-05-12T13:06:33 odb: make the writestream's size a git_off_t Restricting files to size_t is a silly limitation. The loose backend writes to a file directly, so there is no issue in using 63 bits for the size. We still assume that the header is going to fit in 64 bytes, which does mean quite a bit smaller files due to the run-length encoding, but it's still a much larger size than you would want Git to handle.
Edward Thomson f1453c59 2015-02-12T12:19:37 Make our overflow check look more like gcc/clang's Make our overflow checking look more like gcc and clang's, so that we can substitute it out with the compiler instrinsics on platforms that support it. This means dropping the ability to pass `NULL` as an out parameter. As a result, the macros also get updated to reflect this as well.
Edward Thomson 392702ee 2015-02-09T23:41:13 allocations: test for overflow of requested size Introduce some helper macros to test integer overflow from arithmetic and set error message appropriately.

Carlos Martín Nieto ee311907 2014-05-05T16:04:14 odb: ignore files in the objects dir We assume that everything under GIT_DIR/objects/ is a directory. This is not necessarily the case if some process left a stray file in there. Check beforehand if we do have a directory and ignore the entry otherwise.
Russell Belfer 26875825 2014-03-05T13:06:22 Check short OID len in odb, not in backends
Russell Belfer f5753999 2014-03-04T15:34:23 Add exists_prefix to ODB backend and ODB API
Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
Edward Thomson 1d3a8aeb 2013-11-04T18:28:57 move mode_t to filebuf_open instead of _commit
Edward Thomson f966acd1 2013-11-04T15:46:32 Take umask into account in filebuf_commit
Edward Thomson dd64c71c 2013-11-04T14:50:25 Allow backend consumers to specify file mode
Russell Belfer 219d3457 2013-10-01T16:12:15 Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.
nulltoken 209f9b67 2013-09-08T18:25:17 odb: Teach loose backend to return EAMBIGUOUS
nulltoken 4047950f 2013-08-29T14:19:34 odb: Prevent stream_finalize_write() from overwriting Now that #1785 is merged, git_odb_stream_finalize_write() calculates the object id before invoking the odb backend. This commit gives a chance to the backend to check if it already knows this object.

nulltoken d19dd9cf 2013-08-18T23:38:51 odb: Straighten oid prefix handling
Carlos Martín Nieto fe0c6d4e 2013-08-17T01:41:08 odb: make it clearer that the id is calculated in the frontend The frontend is in charge of calculating the id of the objects. Thus the backends should treat it as a read-only value. The positioning in the function signature made it seem as though it was an output parameter. Make the id const and move it from the front to behind the subject (backend or stream).
Carlos Martín Nieto d4e6cf0c 2013-08-15T14:32:47 odb: remove a duplicate object header formatting function
Carlos Martín Nieto 8380b39a 2013-08-15T14:29:39 odb: perform the stream hashing in the frontend Hash the data as it's coming into the stream and tell the backend what its name is when finalizing the write. This makes it consistent with the way a plain git_odb_write() performs the write.
Russell Belfer 8294e8cf 2013-06-22T17:15:31 Constrain mkdir calls to avoid extra mkdirs This updates the calls that make the subdirectories for objects to use a base directory above which git_futils_mkdir won't walk any higher. This prevents attempts to mkdir all the way up to the root of the filesystem. Also, this moves the objects_dir into the loose backend structure and removes the separate allocation, plus does some preformatting of the objects_dir value to guarantee a trailing slash, etc.
Russell Belfer 83cc70d9 2013-04-19T12:48:33 Move odb_backend implementors stuff into git2/sys This moves some of the odb_backend stuff that is related to the internals of an odb_backend implementation into include/git2/sys. Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.

Russell Belfer c3fb7d04 2012-11-27T15:00:49 Make git_odb_foreach_cb take const param This makes the first OID param of the ODB callback a const pointer and also propogates that change all the way to the backends.
Vicent Marti 51e1d808 2012-08-06T12:41:08 Merge remote-tracking branch 'arrbee/tree-walk-fixes' into development Conflicts: src/notes.c src/transports/git.c src/transports/http.c src/transports/local.c tests-clar/odb/foreach.c
Russell Belfer 5dca2010 2012-08-03T17:08:01 Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Russell Belfer 0d0fa7c3 2012-03-16T15:56:01 Convert attr, ignore, mwindow, status to new errors Also cleaned up some previously converted code that still had little things to polish.
Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.
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.

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.
Vicent Martí 0c3bae62 2012-02-15T16:56:56 zlib: Remove custom `git2/zlib.h` header This is legacy compat stuff for when `deflateBound` is not defined, but we're not embedding zlib and that function is always available. Kill that with fire.

Russell Belfer 1744fafe 2012-01-17T15:49:47 Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
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.
Russell Belfer b762e576 2011-11-17T15:10:27 filebuf: add GIT_FILEBUF_INIT and protect multiple opens and cleanups Update all stack allocations of git_filebuf to use GIT_FILEBUF_INIT and make git_filebuf_open and git_filebuf_cleanup safe to be called multiple times on the same buffer.

Roberto Tyley c51065e3 2011-10-24T14:39:03 Tolerate zlib deflation with window size < 32Kb libgit2 currently identifies loose objects as corrupt if they've been deflated using a window size less than 32Kb, because the is_zlib_compressed_data() function doesn't recognise the header byte as a zlib header. This patch makes the method tolerant of all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice it's accuracy in distingushing the standard loose-object format from the experimental (now abandoned) format. It's based on a patch which has been merged into C-Git master branch: https://github.com/git/git/commit/7f684a2aff636f44a506 On memory constrained systems zlib may use a much smaller window size - working on Agit, I found that Android uses a 4KB window; giving a header byte of 0x48, not 0x78. Consequently all loose objects generated by the Android platform appear 'corrupt' :( It might appear that this patch changes isStandardFormat() to the point where it could incorrectly identify the experimental format as the standard one, but the two criteria (bitmask & checksum) can only give a false result for an experimental object where both of the following are true: 1) object size is exactly 8 bytes when uncompressed (bitmask) 2) [single-byte in-pack git type&size header] * 256 + [1st byte of the following zlib header] % 31 = 0 (checksum) As it happens, for all possible combinations of valid object type (1-4) and window bits (0-7), the only time when the checksum will be divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which, due the fields all Commit objects must contain, could never be as small as 8 bytes in size. Given this, the combination of the two criteria (bitmask & checksum) always correctly determines the buffer format, and is more tolerant than the previous version.

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".
Brodie Rao ce8cd006 2011-09-07T15:32:44 fileops/repository: create (most) directories with 0777 permissions To further match how Git behaves, this change makes most of the directories libgit2 creates in a git repo have a file mode of 0777. Specifically: - Intermediate directories created with git_futils_mkpath2file() have 0777 permissions. This affects odb_loose, reflog, and refs. - The top level folder for bare repos is created with 0777 permissions. - The top level folder for non-bare repos is created with 0755 permissions. - /objects/info/, /objects/pack/, /refs/heads/, and /refs/tags/ are created with 0777 permissions. Additionally, the following changes have been made: - fileops functions that create intermediate directories have grown a new dirmode parameter. The only exception to this is filebuf's lock_file(), which unconditionally creates intermediate directories with 0777 permissions when GIT_FILEBUF_FORCE is set. - The test runner now sets the umask to 0 before running any tests. This ensurses all file mode checks are consistent across systems. - t09-tree.c now does a directory permissions check. I've avoided adding this check to other tests that might reuse existing directories from the prefabricated test repos. Because they're checked into the repo, they have 0755 permissions. - Other assorted directories created by tests have 0777 permissions.

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.

Vicent Marti afeecf4f 2011-07-09T02:10:46 odb: Direct writes are back DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is *always* faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.
Vicent Marti f79026b4 2011-07-04T11:43:34 fileops: Cleanup Cleaned up the structure of the whole OS-abstraction layer. fileops.c now contains a set of utility methods for file management used by the library. 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.
Vicent Marti f1d01851 2011-06-16T02:48:48 oid: Uniformize ncmp methods Drop redundant methods. The ncmp method is now public
Vicent Marti fa48608e 2011-06-16T02:36:21 oid: Rename methods Yeah. Finally. Fuck the old names, this ain't POSIX and they don't make any sense at all.
Marc Pegon c09093cc 2011-06-06T10:55:36 Renamed git_oid_match to git_oid_ncmp. As suggested by carlosmn, git_oid_ncmp would probably be a better name than git_oid_match, for it does the same as git_oid_cmp but only up to a certain amount of hex digits.
Marc Pegon aea8a638 2011-05-29T18:00:35 Implemented read_unique_short_oid method for loose backend.
Vicent Marti d0323a5f 2011-06-01T21:25:56 short-oid: Cleanup
Marc Pegon ecd6fdf1 2011-05-27T18:49:09 Added a read_unique_short_oid method to backends, to make it possible to find objects from sha1 prefixes in the future. Default implementations throw GIT_ENOTIMPLEMENTED for strict prefixes (i.e. length < GIT_OID_HEXSZ).

Jakob Pfender f93f8ec5 2011-05-19T12:27:43 odb_loose.c: Return GIT_ENOMEM when allocation fails When trying to inflate a buffer, a GIT_ERROR was returned when malloc() failed. Fix this to return GIT_ENOMEM.
