Fixes an issue where the process sometimes hangs indefinitely after
installation of a tool. This is done by removing the usage of
`task.cancel` within the code for progress bars, and instead checking
the `finished` value within the task.
Previously, the code tried to acquire a lock every
1s while checking if it exists. This caused a
deadlock, since the lock got acquired by the
concurrent process after the installation had
completed and the lock was released.
Fixes a potential TOCTOU bug in the locking mechanism by restructuring
and using file moves which are atomic on both windows and unix.
FIXME: This commit introduces a bug where if there is are two concurrent
processes attempting to install a tool such that the tool has artifact
naming patterns that we understand (and hence do not need to download
every artifact for), the parent installation process (i.e., the one
which started first) yields indefinitely even after installing and
running the tool.
`os.time()` returns a timestamp in seconds, not milliseconds, but the
expiration time was adding 60,000 assuming it was in milliseconds. This
has now been corrected to only add 60 in seconds.
This allows for us to know whether a lock file is too old and hence
invalid, and perform a sanity check to ensure that the resource it is
meant to be protecting is the resource we are trying to access.
* Fixes an issue to do with multiple installation attempts trying
to access the same resources concurrently, causing installation
errors
* Made conditional progress bar a shared state among `__call` metamethod
shorthand and `installTool`, in order to prevent constructing it in
two different places
We did not correctly handle the case if the `gh` CLI was not present,
since `process.spawn` errors. We now wrap it in a `Result.try` and
handle that as required.
* Looks for `$GITHUB_TOKEN` env var, and if not found, tries to run `gh
auth token` to get the token from the GitHub CLI.
* Made a conditional `start` method for the bar, which was previously
missed.
Tools are now stored in the `~/.pesde/bin/.tool_storage` directory, in
order to prevent naming conflicts with other tool linkers. An old
tool_storage directory gets migrated to the new path if present.
* Made bar related conditional operations get constructed by a
`makeCondBar` which returns a table of functions to conditionally handle
a progress bar.
* Moved progress bar boolean out of function args for `installTool` into
global state.
Formerly, we used metatables to get custom `Option` and `Result` objects
which were difficult to type properly, leading to a lot of `unknown` and
`any` casts.
This refactor fixes it by making extensions opt-in, where we import the
extension methods separately from the original implementations, thereby
allowing us to not have to typecast things everywhere.
Previously, we assumed that the tools followed semver, and hence parsed
their versions for comparison. Some tools may not follow semver, and we
should not impose such a requirement as a toolchain management library.
Therefore, we now only check if the requested version string matches an
asset version tag. In order to ensure backwards compatibility, we strip
the leading `v` from the version if present.
* Also breaks down `GithubReleases` into array of `GithubRelease` type
* Adds a `Custom` operation type for internal `Github` class, allowing
user to mention custom request data
* Fix for tools which don't already provide zips with binaries that have
their executable bit set, by executing chmod before attempting to run.
* Uses a different tool_storage structure to prevent changing the tool
name and causing confusion for tools which change their help menu
binary name based on the current exe name.
* Decompression on windows failed since the `Start-Process` cmdlet exited
immediately after spawning the process. Fixed by including the `-Wait`
argument.
* We were using `unzip` on all platforms, and it does not exist on
Windows. Instead, now we use the `Expand-Archive` cmdlet for
decompression on windows.
* Fixes a bug which caused binary parsing fallbacks to not work as
expected, due to a field unexpectedly being `None`.
* Fixed lint error to do with warn being potentially none by defining
our own warn function instead. Also updated fallback binary parsing
fallback warn message to be clearer.
* Fixed decompression error for non-supported artifacts by only
decompressing those we support.
