* plumbing: format: pktline, Accept oversized pkt-lines up to 65524 bytes The canonical Git client successfully decodes sideband packets up to 65524 bytes in length (4-byte header + 65520-byte payload). The Git protocol documentation was updated in August 2016 to reduce the maximum payload size to 65516 bytes, however old implementations still exist in the wild emitting 65520-byte payloads. As there is no technical difficulty with accepting (not emitting) larger payload sizes, this change adjusts the limit check to allow successful decoding of packets up to 65524 bytes. This change increases compatibility with the current canonical Git implementation. Doc changes from August 2016: git/git@7841c48#diff-52695c8fe91b78b70cea44562ae28297L67 Current packet buffer size is still LARGE_PACKET_MAX (+1 null): https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/sideband.c#L24 https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/sideband.c#L36 LARGE_PACKET_MAX definition: https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/pkt-line.h#L100 Signed-off-by: Joseph Vusich <jvusich@amazon.com> * add PlainOpen variant to find .git in parent dirs This is the git tool's behavior that people are used to; if one runs a git command in a repository's subdirectory, git still works.

The current code iterates all the references in the remote to check if they match the refspec. This is OK when the refspec is a wildcard but is a waste of time when they are not. A hash with references is generated for fast access before starting the update and used only when the refspec is not a wildcard. In a repository with 7800 references this meant 7800 * 7800 checks. With the current code it took 8m30s to update the references. With the new code it takes less than 0.5s. References are already extensively tested in remote_test.go.

Signed-off-by: David Symonds <dsymonds@golang.org> * packfile: improve Index memory representation to be more compact Instead of using a map for offset indexing, use a sorted slice.

Signed-off-by: David Symonds <dsymonds@golang.org> * Remote.Fetch: error on missing remote reference Signed-off-by: Máximo Cuadros <mcuadros@gmail.com> * storage/filesystem: avoid norwfs build flag norwfs build flag was used to work on filesystems that do not support neither opening a file in read/write mode or renaming a file (e.f. sivafs). This had two problems: - go-git could not be compiled to work properly both with regular filesystems and limited filesystems at the same time. - the norwfs trick was not available on Windows. This PR removes the norwfs build flag, as well as the windows conditional flag on the dotgit package. For the file open mode, we use the new billy capabilities, to check at runtime if the filesystem supports opening a file in read/write mode or not. For the renaming, we just try and fallback to alternative methods if billy.ErrNotSupported is returned. Signed-off-by: Santiago M.

Fixes src-d#883 FindEntry will return ErrDirNotFound if the directory doesn't exist. But it doesn't return a public error if the entry itself is missing. This exposes the internal error ErrEntryNotFound, so users can programmatically check for this condition. Signed-off-by: James Ravn <james@r-vn.org> * plumbing/transport/internal: common, add support of Gogs for ErrRepositoryNotFound, avoiding to get an 'unknown error: '. Add some tests for existing supported services (github, gitlab, etc...) too. Signed-off-by: Jerome Doucet <jerdct@gmail.com> * plumbing/object: fix pgp signature encoder/decoder The way of reading pgp signatures was searching for pgp begin line in the header. This caused problems when this string appeared and was not part of the signature. For example if it appears in the message as an example or is part of the author name the decoder starts treating it as a signature. In this state the code was not able to notice then the header ended so it entered in an infinite loop searching for pgp end string. Now it uses the same method as original git. Searches for gpgsig section in header and starts getting all lines until the next part. In encoder the string used to add signatures was incorrect. It is now changed to the proper "gpgsig" string instead of "pgpsig".

Ultimately, this results in a corrupt object, rendering the object unverifiable with the signature in the commit. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Add ability to PGP sign commits This adds the ability to sign commits by adding the SignKey field to CommitOptions. If present, the commit will be signed during the WorkTree.Commit call. The supplied SignKey must already be decrypted by the caller. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Remove use of strings.Builder This was added in Go 1.10 and is not supported on Go 1.9. Switched to bytes.Buffer to ensure compatibility. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Remove old hash validation code This will not work for a signed commit as with the GPG signature being a part of the commit, the hash is now non-deterministic. Verification of the commit is done through the validation of the signature. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Add extra test for testing bad key error case I'm hoping this helps get codecov to a tolerable delta. :) Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * dotgit: fix object delete test Signed-off-by: Santiago M. Mola <santi@mola.io> * object: fix panic when reading object header When the first line of the pgp signature is an empty line or some header is malformed it crashes as there's no data for the header element. For example, if author name is "\n". Signed-off-by: Javi Fontan <jfontan@gmail.com> * Fixed an edge case for .gitignore Fixes src-d#923 Signed-off-by: Fedor Korotkov <fedor.korotkov@gmail.com> * plumbing/idxfile: object iterators returns entries in offset order In the latest change the order was changed from offset order in packfiles to hash order. This makes reading all the objects not as efficient as before. It also created problems when the previous order was expected. Also added EntriesByOffset to indexes. Signed-off-by: Javi Fontan <jfontan@gmail.com> * git: Add tagging support This adds a few methods: * CreateTag, which can be used to create both lightweight and annotated tags with a supplied TagObjectOptions struct. PGP signing is possible as well. * Tag, to fetch a single tag ref. As opposed to Tags or TagObjects, this will also fetch the tag object if it exists and return it along with the output. Lightweight tags just return the object as nil. * DeleteTag, to delete a tag. This simply deletes the ref. The object is left orphaned to be GCed later. I'm not 100% sure if DeleteTag is the correct behavior - looking for details on exactly *what* happens to a tag object if you delete the ref and not the tag were sparse, and groking the Git source did not really produce much insight to the untrained eye. This may be something that comes up in review. If deletion of the object is necessary, the in-memory storer may require some updates to allow DeleteLooseObject to be supported. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing: object, correct tag PGP encoding As with the update in ec3d2a8, tag encoding needed to be corrected to ensure extra newlines were not being added in during tag object encoding, so that it did not corrupt the object for verification. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing: object, don't add extra newline on PGP signature Tag encoding/decoding seems to be a lot more sensitive to requiring the exact expected format in the object, which generally includes messages canonicalized so that they have a newline on the end (even if they didn't before). As such, the message should be written with the newline (no need for an extra), and the PGP signature right after that, which will be newline split already, so there's no need to split it again. All of this means it's very important for the caller to send the message in the correct format - which I'm correcting in the next commit. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Canonicalize incoming annotated tag messages Tag messages are highly sensitive to being in the expected format, especially when encoding/decoding for PGP verification. As such, we do a simple trimming of whitespace on the incoming message and add a newline on the end, to ensure there are no surprises here. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Replace test signing key with one with longer expiry The old one was created with defaults, which would have caused CI failures in 2 years. The new one is valid for 10 years: > gpg --list-secret-keys /root/.gnupg/pubring.kbx ------------------------ sec rsa4096 2018-08-22 [SC] [expires: 2028-08-19] 93A17FF01E54328546087C8E029395402EFCCD53 uid [ unknown] foo bar <foo@foo.foo> Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing, storage: add bases to the common cache After clone only resolved deltas were added to the cache. This caused slowdowns in small repositories where most objects can be held in cache. It also makes packfiles reuse delta cache from the store. Previously it created a new delta cache each time a packfile object was created. This also slowed down a bit accessing objects and had an impact on memory consumption when bases are added to the cache. Signed-off-by: Javi Fontan <jfontan@gmail.com> * git: Discern tag target type from supplied hash I figured there was a way to do this without having to have TagObjectOptions supply this in - there is. Added support for this in and removed the object type from TagObjectOptions. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Don't return tag object with Tag, adjust docs for Tag and Tags I've mainly noticed that in using the current Tag function, that there were lots of times that I was ignoring the ref or the object, depending on what I needed. This was evident in the tests as well. As such, I think it just makes more sense for a singular tag fetcher to return just a ref, through which the caller may grab the annotation if they need it, and if it exists. Also, contrary to the docs on Tags, all tags have a ref, even if they are annotated. The difference between a lightweight tag and an annotated tag is the presence of the tag object, which the ref will point to if the tag is annotated. As such I've adjusted the docs with an example as to how one can get the annotation for a tag ref through the iterator.

Wiedmann <zaquestion@gmail.com> * git: add Static option to PlainOpen Also adds Static configuration to Storage and DotGit. This option means that the git repository is not expected to be modified while open and enables some optimizations. Each time a file is accessed the storer tries to open an object file for the requested hash. When this is done for a lot of objects it is expensive. With Static option a list of object files is generated the first time an object is accessed and used to check if exists instead of using system calls. A similar optimization is done for packfiles.

Signed-off-by: Javi Fontan <jfontan@gmail.com> * storage/dotgit: add KeepDescriptors option This option maintains packfile file descriptors opened after reading objects from them. It improves performance as it does not have to be opening packfiles each time an object is needed. Also adds Close to EncodedObjectStorer to close all the files manualy.

Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Don't touch tag objects orphaned by tag deletion Deleting a tag ref for an annotated tag in normal git behavior does not delete the tag object right away. This is handled by the normal GC process. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Add some tests for annotated tag deletion Added a couple of tests for annotated tag deletion: * The first one is a general test and should work regardless of the fixture used - the tag object could possibly be packed, so we do a prune *and* a repack operation before testing to see if the object was GCed correctly. * The second one actually creates the tag to be deleted, so that the tag object gets created as a loose, unpacked object. This is so we can effectively test that purning unpacked objects is now working 100% correctly (this was failing before because tag objects were not supported for walking). Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: s/TagObjectOptions/CreateTagOptions/ Just renaming the TagObjectOptions type to CreateTagOptions so that it's consistent with the other option types.

* plumbing: format: pktline, Accept oversized pkt-lines up to 65524 bytes The canonical Git client successfully decodes sideband packets up to 65524 bytes in length (4-byte header + 65520-byte payload). The Git protocol documentation was updated in August 2016 to reduce the maximum payload size to 65516 bytes, however old implementations still exist in the wild emitting 65520-byte payloads. As there is no technical difficulty with accepting (not emitting) larger payload sizes, this change adjusts the limit check to allow successful decoding of packets up to 65524 bytes. This change increases compatibility with the current canonical Git implementation. Doc changes from August 2016: git/git@7841c48#diff-52695c8fe91b78b70cea44562ae28297L67 Current packet buffer size is still LARGE_PACKET_MAX (+1 null): https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/sideband.c#L24 https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/sideband.c#L36 LARGE_PACKET_MAX definition: https://github.com/git/git/blob/468165c1d8a442994a825f3684528361727cd8c0/pkt-line.h#L100 Signed-off-by: Joseph Vusich <jvusich@amazon.com> * add PlainOpen variant to find .git in parent dirs This is the git tool's behavior that people are used to; if one runs a git command in a repository's subdirectory, git still works.

The current code iterates all the references in the remote to check if they match the refspec. This is OK when the refspec is a wildcard but is a waste of time when they are not. A hash with references is generated for fast access before starting the update and used only when the refspec is not a wildcard. In a repository with 7800 references this meant 7800 * 7800 checks. With the current code it took 8m30s to update the references. With the new code it takes less than 0.5s. References are already extensively tested in remote_test.go.

This had two problems: - go-git could not be compiled to work properly both with regular filesystems and limited filesystems at the same time. - the norwfs trick was not available on Windows. This PR removes the norwfs build flag, as well as the windows conditional flag on the dotgit package. For the file open mode, we use the new billy capabilities, to check at runtime if the filesystem supports opening a file in read/write mode or not. For the renaming, we just try and fallback to alternative methods if billy.ErrNotSupported is returned. Signed-off-by: Santiago M.

Signed-off-by: Jerome Doucet <jerdct@gmail.com> * plumbing/object: fix pgp signature encoder/decoder The way of reading pgp signatures was searching for pgp begin line in the header. This caused problems when this string appeared and was not part of the signature. For example if it appears in the message as an example or is part of the author name the decoder starts treating it as a signature. In this state the code was not able to notice then the header ended so it entered in an infinite loop searching for pgp end string. Now it uses the same method as original git. Searches for gpgsig section in header and starts getting all lines until the next part. In encoder the string used to add signatures was incorrect. It is now changed to the proper "gpgsig" string instead of "pgpsig".

This makes reading all the objects not as efficient as before. It also created problems when the previous order was expected. Also added EntriesByOffset to indexes. Signed-off-by: Javi Fontan <jfontan@gmail.com> * git: Add tagging support This adds a few methods: * CreateTag, which can be used to create both lightweight and annotated tags with a supplied TagObjectOptions struct. PGP signing is possible as well. * Tag, to fetch a single tag ref. As opposed to Tags or TagObjects, this will also fetch the tag object if it exists and return it along with the output. Lightweight tags just return the object as nil. * DeleteTag, to delete a tag. This simply deletes the ref. The object is left orphaned to be GCed later. I'm not 100% sure if DeleteTag is the correct behavior - looking for details on exactly *what* happens to a tag object if you delete the ref and not the tag were sparse, and groking the Git source did not really produce much insight to the untrained eye. This may be something that comes up in review. If deletion of the object is necessary, the in-memory storer may require some updates to allow DeleteLooseObject to be supported. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing: object, correct tag PGP encoding As with the update in ec3d2a8, tag encoding needed to be corrected to ensure extra newlines were not being added in during tag object encoding, so that it did not corrupt the object for verification. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing: object, don't add extra newline on PGP signature Tag encoding/decoding seems to be a lot more sensitive to requiring the exact expected format in the object, which generally includes messages canonicalized so that they have a newline on the end (even if they didn't before). As such, the message should be written with the newline (no need for an extra), and the PGP signature right after that, which will be newline split already, so there's no need to split it again. All of this means it's very important for the caller to send the message in the correct format - which I'm correcting in the next commit. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Canonicalize incoming annotated tag messages Tag messages are highly sensitive to being in the expected format, especially when encoding/decoding for PGP verification. As such, we do a simple trimming of whitespace on the incoming message and add a newline on the end, to ensure there are no surprises here. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Replace test signing key with one with longer expiry The old one was created with defaults, which would have caused CI failures in 2 years. The new one is valid for 10 years: > gpg --list-secret-keys /root/.gnupg/pubring.kbx ------------------------ sec rsa4096 2018-08-22 [SC] [expires: 2028-08-19] 93A17FF01E54328546087C8E029395402EFCCD53 uid [ unknown] foo bar <foo@foo.foo> Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * plumbing, storage: add bases to the common cache After clone only resolved deltas were added to the cache. This caused slowdowns in small repositories where most objects can be held in cache. It also makes packfiles reuse delta cache from the store. Previously it created a new delta cache each time a packfile object was created. This also slowed down a bit accessing objects and had an impact on memory consumption when bases are added to the cache. Signed-off-by: Javi Fontan <jfontan@gmail.com> * git: Discern tag target type from supplied hash I figured there was a way to do this without having to have TagObjectOptions supply this in - there is. Added support for this in and removed the object type from TagObjectOptions. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Don't return tag object with Tag, adjust docs for Tag and Tags I've mainly noticed that in using the current Tag function, that there were lots of times that I was ignoring the ref or the object, depending on what I needed. This was evident in the tests as well. As such, I think it just makes more sense for a singular tag fetcher to return just a ref, through which the caller may grab the annotation if they need it, and if it exists. Also, contrary to the docs on Tags, all tags have a ref, even if they are annotated. The difference between a lightweight tag and an annotated tag is the presence of the tag object, which the ref will point to if the tag is annotated. As such I've adjusted the docs with an example as to how one can get the annotation for a tag ref through the iterator.

This option means that the git repository is not expected to be modified while open and enables some optimizations.

Signed-off-by: Javi Fontan <jfontan@gmail.com> * storage/filesystem: compare files using offset in test Using equals to compare files it uses diff to do so. This can potentially consume lots of ram. Changed the comparison to use file offsets. If the descriptor is reused the offset is maintained.

Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Don't touch tag objects orphaned by tag deletion Deleting a tag ref for an annotated tag in normal git behavior does not delete the tag object right away. This is handled by the normal GC process. Signed-off-by: Chris Marchesi <chrism@vancluevertech.com> * git: Add some tests for annotated tag deletion Added a couple of tests for annotated tag deletion: * The first one is a general test and should work regardless of the fixture used - the tag object could possibly be packed, so we do a prune *and* a repack operation before testing to see if the object was GCed correctly. * The second one actually creates the tag to be deleted, so that the tag object gets created as a loose, unpacked object. This is so we can effectively test that purning unpacked objects is now working 100% correctly (this was failing before because tag objects were not supported for walking).

Hi,
This is in reference to #826
This commit basically performs what
git log -- <filename>should do.I've added a new class called
commit_walker_file, which wraps around the iterator of the originalLogfunction and returns those commits whoseDifftreecontains the file-path specified. I've added tests for scenarios I could think of.Kindly let me know if there's something I can do better here.
