|
|
* review guidelines/community standards
|
|
- (Linux Foundation Core Infrastructure Initiative Best Practices)[https://bestpractices.coreinfrastructure.org/]
|
|
- (Readme Maturity Level)[https://github.com/LappleApple/feedmereadmes/blob/master/README-maturity-model.md]
|
|
- (Github Community Profile)[https://github.com/nih-at/libzip/community]
|
|
|
|
* test different crypto backends with TravisCI.
|
|
|
|
* test for zipcmp reading directory (requires fts)
|
|
|
|
* improve man page formatting of tagged lists on webpage (`<dl>`)
|
|
|
|
* test error cases with special source
|
|
- tell it which command should fail
|
|
- use it both as source for `zip_add` and `zip_open_from_source`
|
|
- `ziptool_regress`:
|
|
- `-e error_spec`: source containing zip fails depending on `error_spec`
|
|
- `add_with_error name content error_spec`: add content to archive, where source fails depending on `error_spec`
|
|
- `add_file_with_error name file_to_add offset len error_spec`: add file to archive, len bytes starting from offset, where source fails depending on `error_spec`
|
|
- `error_spec`:
|
|
- source command that fails
|
|
- error code that source returns
|
|
- conditions that must be met for error to trigger
|
|
- Nth call of command
|
|
- read/write: total byte count so far
|
|
- state of source (opened, EOF reached, ...)

# Later
|
|
|
|
## macOS / iOS framework
|
|
|
|
* get cmake to optionally build frameworks
|
|
|
|
## Prefixes
|
|
|
|
For example for adding extractors for self-extracting zip archives.
|
|
````c
|
|
zip_set_archive_prefix(struct zip *za, const zip_uint8_t *data, zip_uint64_t length);
|
|
const zip_uint8_t *zip_get_archive_prefix(struct zip *za, zip_uint64_t *lengthp);
|
|
````
|
|
|
|
## Compression
|
|
|
|
* add lzma support
|
|
|
|
## API Issues
|
|
|
|
* `zip_get_archive_comment` has `int *lenp` argument. Cleaner would be `zip_uint32_t *`.
|
|
rename and fix. which other functions for naming consistency?
|
|
* rename remaining `zip_XXX_{file,archive}_*` to `zip_{file,archive}_XXX_*`?
|
|
* compression/crypt implementations: how to set error code on failure
|
|
* compression/crypt error messages a la `ZIP_ER_ZLIB` (no detailed info passing)
|
|
|
|
## Features
|
|
|
|
* add seek support for AES-encrypted files
|
|
* consistently use `_zip_crypto_clear()` for passwords
|
|
* support setting extra fields from `zip_source`
|
|
* introduce layers of extra fields:
|
|
* original
|
|
* from `zip_source`
|
|
* manually set
|
|
* when querying extra fields, search all of them in reverse order
|
|
* add whiteout (deleted) flag
|
|
* allow invalid data flag, used when computing extra field size before writing data
|
|
* new command `ZIP_SOURCE_EXTRA_FIELDS`
|
|
* no support for multiple copies of same extra field
|
|
* delete all extra fields during `zip_replace()`
|
|
* function to copy file from one archive to another
|
|
* set `O_CLOEXEC` flag after fopen and mkstemp
|
|
* `zip_file_set_mtime()`: support InfoZIP time stamps
|
|
* support streaming output (creating new archive to e.g. stdout)
|
|
* add function to read/set ASCII file flag
|
|
* `zip_commit()` (to finish changes without closing archive)
|
|
* add custom compression function support
|
|
* `zip_source_zip()`: allow rewinding
|
|
* add `zip_abort()` to allow aborting `zip_close()` (can be called from progress callback)
|
|
* `zipcmp`: add option for file content comparison
|
|
* `zipcmp`: add more paranoid checks:
|
|
* external attributes/opsys
|
|
* last_mod
|
|
* version needed/made by
|
|
* general purpose bit flags
|
|
* add more consistency checks:
|
|
* for stored files, test compressed = uncompressed
|
|
* data descriptor
|
|
* local headers come before central dir
|
|
* support for old compression methods?
|
|
|
|
## Bugs
|
|
|
|
* support InfoZIP encryption header extension (copy data descriptor for encrypted files)
|
|
* ensure that nentries is small enough not to cause overflow (size_t for entry, uint64 for CD on disk)
|
|
* check for limits imposed by format (central dir size, file size, extra fields, ...)
|
|
* `_zip_u2d_time()`: handle `localtime(3)` failure
|
|
* POSIX: `zip_open()`: check whether file can be created and fail if not
|
|
* fix inconsistent usage of valid flags (not checked in many places)
|
|
* `cdr == NULL` -> `ER_NOENT` vs. `idx > cdir->nentry` -> `ER_INVAL` inconsistent (still there?)
|
|
|
|
|
|
## Cleanup
|
|
|
|
* drop _LIBZIP suffixes in cmake defines (no longer needed since they no longer appear in zipconf.h)
|
|
* go over cdir parser and rename various offset/size variables to make it clearer
|
|
* use bool
|
|
* use `ZIP_SOURCE_SUPPORTS_{READABLE,SEEKABLE,WRITABLE}`
|
|
* use `zip_source_seek_compute_offset()`
|
|
* get rid of `zip_get_{compression,encryption}_implementation()`
|
|
* use `zip_*int*_t` internally
|
|
|
|
## Infrastructure
|
|
|
|
* rewrite `make_zip_errors.sh` in cmake
|
|
* rewrite `make_zip_err_str.sh` in cmake
|
|
* configure appveyor for Windows builds of libzip
|
|
|
|
## Test Case Issues
|
|
|
|
* add test case for clone with files > 4k
|
|
* consider testing for malloc/realloc failures
|
|
* Winzip AES support
|
|
* test cases decryption: <=20, >20, stat for both
|
|
* test cases encryption: no password, default password, file-specific password, 128/192/256, <=20, >20
|
|
* support testing on macOS
|
|
* add test cases for lots of files (including too many)
|
|
* add test cases for holes (between files, between files and cdir, between cdir and eocd, + zip64 where appropriate)
|
|
* unchange on added file
|
|
* test seek in `zip_source_crc()`
|
|
* test cases for `set_extra*`, `delete_extra*`, `*extra_field*`
|
|
* test cases for in memory archives
|
|
* add
|
|
* delete
|
|
* delete all
|
|
* modify
|
|
* use gcov output to increase test coverage
|
|
* add test case to change values for newly added files (name, compression method, comment, mtime, . . .)
|
|
* `zip_open()` file less than `EOCDLEN` bytes long
|
|
* test calls against old API
|
|
* run regression tests also from CMake framework
|
|
* rename file to dir/ and vice versa (fails)
|
|
* fix comment test to be newline insensitive
|
|
* check if http://bugs.python.org/issue20078 provides ideas for new tests
|
|
|

|
|
* unchange added/replaced file
|

|
|
|
## Unsorted
|
|
|
|
* `zip_source_file()`: don't allow write if start/len specify a part of the file
|
|
* script to check if all exported symbols are marked with `ZIP_EXTERN`, add to make distcheck
|
|
|
|
* document: `zip_source_write()`: length can't be > `ZIP_INT64_MAX`
|
|
* document: `ZIP_SOURCE_CLOSE` implementation can't return error
|
|
* keep error codes in man pages in sync
|
|
* document error codes in new man pages
