Causes `get_hash` to verify the hash length, and check that the hash can
be unhexlified properly.
Fixes the interface for `get_hash` so that the caller does not have to
run `binascii.unhexlify` or verify its output.
I don't think we can really call the `Updates.xml` files that we are
parsing 'untrusted xml', because we are checking that they match the
sha256 checksum. However, I don't think there's any good reason not to
use a more secure parsing algorithm.
`MetadataFactory.fetch_http` must often download HTML pages, not
Updates.xml files. download.qt.io does not store checksums for these
files, so this particular function must be allowed to download these
pages without using a checksum.
This prevents `list-*` from printing any module whose uncompressed size
is 40 bytes or less.
I have found a couple of modules that are exactly 40 bytes, and they
include no files, only empty directories. If any user tries to install
these modules, they will think that aqt failed to install the module
without printing any error message. I prefer to avoid this issue
by preventing `aqt list-*` from printing them.
`aqt install-*` is unaffected by this change, and it can still install
modules that contain no files. It is likely that we will need to print
a warning when this occurs.
If any user disagrees with the threshold value of 40 bytes, they are
free to adjust that value to their liking in `settings.ini`.
On August 19, the Qt repo added a new wasm release for Qt 6.2.0.
`list-qt` currently prints that the `wasm` extension is available for
that version of Qt, but it will not let the user use it to query
modules and architectures, because of a hardcoded version check.
This change rewrites the version check so that a user may make queries.
This also moves the `format_suggested_follow_up` function into the new
AqtException class, refactors `show_list` to use the new exceptions,
and tests the new code appropriately.
This alters `suggested_follow_up` to return a list of strings.
This makes testing easier, as well as making it easier to change the
way the suggestions are displayed.
This change also fixes an error in the suggestions ('list' was missing
from the suggested command), and fixes some punctuation errors.
This also adds a print formatter that displays the suggestions nicely
in the terminal.
`Versions.flattened()` returns a flat list of all the versions in the
Versions object, without any stratification by minor version.
This commit also updates the type hint for Versions.__iter__, which
returns a Generator.
