ocaml-git - Do not use mmap

Published by samoht over 8 years ago

Do not mmap files, as there is no way to easily control the unmap of bigarrays. This remove EMFILE errors under load (#133, @talex5)
Fix comparison of entries in the index file. This fix a random issue which might happen when entries in a pack file are checkout and updated (@samoht)

ocaml-git - Support latest cohttp and revert API break.

Published by samoht over 8 years ago

Support cohtpp 0.19.1. (#119, @rgrinberg)
Revert API break for the Sync functor. Now still takes only a Store.S
as parameter. (#120)

ocaml-git - SHA and Inflate abstractions

Published by samoht about 9 years ago

Changes to the Search API:
- Remove find_exn
- the type t has a new case Tree_root to represent tree roots
- the type path is now structured (not a list of strings anymore).
  this removes the confusing semantics of empty strings in paths.
Changes to the Global_graph API:
- closure takes an optional full argument to work over
  commit objects only
- All the arguments of pack are labelled and its result type
  has changed.
- Add keys to return the topological sort of keys in the graph.
Improve the size of pack files received when fetching (#115)
- advertise the fact that ocaml-git clients support ofs-delta
  and thin-pack
- Compute a minimal set of haves to send to the server after
  the discovery phase, where we already know all the server
  references (#114)
Unpack shallow pack files after a fetch
Full support for shallow packs (#81)
During fetch, we now respect the "allow-reachable-sha1-in-want"
server (non-)capability. A proper error is reported to the client
if that's not the case.
Parametrize the codebase over the Inflate implementation. Useful
to change the inflate algorithm (or to not use any at all, which
would be what we want for big files and/or for efficient writes)
and to simplify the port to other backends. Store.S implementations
now expose their Inflate implementation.
Parametrize the codebase over the SHA implementation. Useful to change
the SHA algorihm (the unix backend provides SHA256) or simplify the
port to other backends (the mirage backend uses a pure OCaml implementation
extracted from uuidm). Store.S implementations now expose their Digest
implementation (#68)
Better sync API (#113)
- Change the arguments of Sync.fetch
- Remove Sync.clone
- Add Sync.populate to be called after a fetch to properly populate
  the local Git repository (similar to what git clone does).
- Add ogit clone --no-checkout and make ogit clone --bare more similar
  to the same git command.
Support Github http(s) URLs without .git (#111)
Add a dot_git optional parameter to Store.create to specify where
the Git metadata should be stored (default is still <root>/.git). This
is useful to properly support bare repositories (#110)
Full support for 32 bit platform (ie. continue the patch started in 1.6.2).
Rework the Git.Pack and Git.Pack_index API to speed-up random access.
Add a Git.SHA.Array module to work with contiguous arrays of SHA1.
Rename Git.SHA.lenght to Git.SHA.hex_length to avoid confusion.
Expose Git.SHA.of_short_hex to create short hashes. Git.SHA.of_hex now
only accept 40 characters hexa-decimal strings.
Improve the output of ogit clone by showing progress when the pack file
is downloaded and when the delta are resolved.

ocaml-git - Support 32bit architectures

Published by samoht over 9 years ago

Support 32 bit platform by avoiding creating large strings. This also improve
the performance of reading and synchronizin large pack files
(#103, @gregtatcam)

ocaml-git - Bug fixes in the smart HTTP protocol

Published by samoht over 9 years ago

Fix a bug in ogit pull using the smart HTTP protocol when the HTTP temporary
buffer could sometimes be overfill.
Avoid closing twice the same fd in the smart HTTP protocol.
Avoid the GC to close a fd while we are still using a channel built on top of
it -- this affects the smart HTTP protocol only.
Add an opam file for the mirage-git package.

ocaml-git - Fix regressions in `Sync.clone`, fix reading hashes in `.git/HEAD`, change API to reset the store and start to improve 32bit support

Published by samoht over 9 years ago

Allow some references to contain pointer to other references (#96)
Improve the support for 32bit architectures (#97)
Add Reference.pp_head_contents and Reference.equal_head_contents.
Remove Store.clear and replace it by Memory.clear, Memory.clear_all
and FS.remove. This let users have a finer control over the memory
consumption of the program over time (related to #90)
Rename all pp_hum functions into pp.
Fix regression in Sync.fetch and add unit-tests (running only in slow mode).
Fix reading of .git/HEAD when the contents is a commit hash.
Depends on Stringext for all the extra string function needed.

The previous command is renamed to ogit cat (#75 by @codinuum)
ogit now supports short hashes instead of full SHA1 (#75 by @codinuum)

than the previous representation (#75 by @codinuum)

Published by samoht over 9 years ago

Fix multi round-trips in the smart HTTP protocol. This fixes
depth-limited clones (#71) and fetches.
Create the git.http library for abstracting away bits of the
smart HTTP protocol.
Add User-Agent in the headers of the smart HTTP protocol. This

ocaml-git - Remove `OGITTMPDIR`

Published by samoht over 9 years ago

Remove the OGITTMPDIR and alway store temp files under git/tmp (mirage/irmin#132)

ocaml-git - Fix bug in LRU cache, flush the `cat-file` commands

Published by samoht over 9 years ago

Fix LRU cache: SHA1 should be unique in the cache (regression
introduced in 1.4.3). This was causing confusing read results
under load.
Reading objects now updates the LRU cache
Fix a regression in ogit cat-file which were displaying nothing
for small objects.

ocaml-git - Fix for non-bare repositories, remove stdout/stderr messages

Published by samoht over 9 years ago

Fix the filesystem updates for non-bare repositories (reported by @avsm)
Git.write_index now takes an optional index argument
Index entries should be fixed alphabetically
Remove raw printf (#60)
More flexibility on where to write temp files. The directory name can be
configured by write calls, and the default is OGITTMPDIR if set,
then Filename.get_temp_dir_name -- as it was in 1.4.5, see #51

ocaml-git - Improve LRU settings and add the `git.top` package

Published by samoht over 9 years ago

Expose Git.Value.Cache.set_size to change the LRU cache size
Reduce the default LRU cache size (in 1.4.4 it was set to 64k, now it's 512)
More precise type for commit dates
Add git.top to load toplevel printers for Git values

ocaml-git - Support packed references

Published by samoht almost 10 years ago

Support packed-refs files, to read references packed by git gc (reported
by Gregory Tsipenyuk)
Fix the filesystem backend when TMPDIR is not on the same partition as the
Git repository (#51, patch from @vklquevs)

ocaml-git - More protocol support, more stability

Published by samoht almost 10 years ago

Support the smart HTTP Git protocol (#26)
Best-effort creation of files when expanding the index into the filesystem:
Skip the invalid filenames and continue. Users are expected to sanitize
their filenames if they want to use a non-bare repository (#11)
Overwrite changed file when expanding the index into the filesystem (#4)
Do not recompute the hash of blob files when expanding the index into the
filesystem. This help fixing a speed issue with non-bare repo with lots of
file.
