* fix: write index.yaml file atomically
This refactors the already-existing `AtomicWriteFile` utility
to a central location and uses it to write index files
atomically.
This is done to avoid having half-written index files break
client requests.
Drive-bys:
- Add test for AtomicWriteFile.
- Add test IndexFile.WriteFile.

The completion of charts was using 'helm search repo' which can be
quite slow as it must parse the entire yaml of every repo cache file.
Using completion for a chart name can end up triggering multiple calls
to 'helm search'; this makes the user experience poor, as there is
a delay of over a second at every <TAB> press.
This commit creates a cache file for each repo which contains the list
of charts for that repo. The completion logic then uses this new
cache file directly and obtains the chart names very quickly.
With only the stable repo configured, this optimization makes the
completion of charts about 85 times faster, going from 1.2 seconds to
0.014 seconds; such a difference gives a much better user experience
when completing chart names.
On the other hand, adding the creation of the chart list cache file to
'helm repo update' or 'helm repo add' is pretty much negligible compared
to the downloading of the index file.
It is also worth noting that when more repos are configured,
'helm search repo' only becomes slower, while the completion logic that
uses the new chart list cache file will not be affected as it only looks
for the single relevant repo file.

Fixes a few bugs related to tls config when installing charts:
1. When installing via relative path, tls config for the selected
repository was not being set.
2. The `--ca-file` flag was not being passed when constructing the
downloader.
3. Setting tls config was not checking for zero value in repo
config, causing flag to get overwritten with empty string.
There's still a few oddities here. I would expect that the flag
passed in on the command line would override the repo config, but
that's not currently the case. Also, we always set the cert, key
and ca files as a trio, when they should be set individually
depending on combination of flags / repo config.

Introduce the `--devel` flag for `helm repo search` command.
`helm repo search` - searches only for stable releases, prerelease versions will be skip
`helm repo search --devel` - searches for releases and prereleases (alpha, beta, and release candidate releases)
`helm repo search --version 1.0.0 - searches for release in version 1.0.0

This commit replaces usage of github.com/ghodss/yaml with it's forked
version maintained by SIG community. The replaced library has
low-to-none support activity unlike the latter. We believe the new
Helm branch could benefit from using the community-supported version on
a long-term run as yaml parser is a key component of Helm chart rendering
engine.
This commit locks sigs.k8s.io/yaml dependency version on 1.1.0 which
is backwards compatible with ghodss/yaml 1.0.0.
This change also resolves the outdated dependency version lock for
ghodss/yaml (currently 1.0.0) and makes it possible to port changes from
https://github.com/helm/helm/pull/6010 to dev-v3.

New users to helm don't always run `helm init` (e.g. if their cluster
already has helm installed). The user's initial interaction with any of
helm's repository commands (e.g. `helm repo list`) will then be an error
message due to a missing repositories.yaml in their local config.
Give the user a little hint about how to fix the error without them having
to hunt through the man/help pages.
* Closes#2937
Added required dependency to run make test in developer's guide
* Fixed base URL appending when chart address is not absolute
* Removed requirement from developers.md
* Fixed unnecessary line breaks
* Added tests for query string repo
* Returning URL along with error
This prevents clients from seeing half-written files because
on POSIX systems renaming a file is an atomic operation.
Drive-by: Add test for repo file permission.
This flattens the getter package tree, adds tests, and changes a little
bit of the terminology to follow Go idioms. This also makes much of the
getter API private to begin with. This will give us more flexibility in
the future.
It is now possible to create plugins with chart download capabilities for custom, non-http protocols.
Furthermore it is possible to reuse helm packages to implement alternative clients with these custom downloader functions.
This exposes the skip-refresh flag to helm init to make it possible to
initialize Helm without fetching the index.yaml of the stable repo.
This mirrors the behavior of 'helm dep up's skip-refresh flag.
Closes#2127
When downloader package moved to under /pkg, helmpath functions got called still from it, while it is under /cmd. This commit fixes the issue by moving helmpath after the downloader to have only cmd->pkg and pkg->pkg calls.
A regression was committed during 2.2.0 that broke the repositories.yaml
file format, switching the cache path from relative to absolute. This
fixes the error.
Closes#1974
This switches the local chart repo to use 127.0.0.1 instead of localhost
so that the net library does not negotiate localhost to an IPv6 address,
which is known to cause issues in some Docker containers.
Breaking Change: When testing on a system that does NOT have IPv4
configured, this will break 'helm serve'. We estimate this will impact
none of the current user base.
Closes#1410
Previous versions of Helm had placeholder text in the index.yaml file.
This generates an HTML index for 'helm serve'. It also has a
refactoring of the server so that the server can be tested.
Closes#1397
This prevents the index command from recursing through directories.
Behind the scenes, it swaps out the repository logic for the index file
logic.
Closes#1328
Between Alpha.4 and Alpha.5 there was a change in the indexing logic.
This prevent indices from being appended to (because those index files
were often broken). This change allows the user to explicitly merge an
existing index and a generated index.
Closes#1334
I wrote urlJoin to fix URL joining, but I put it in the wrong place and
never used it. This moves it to the right place, and replaces the hacky
previous solution.
This removes the requirement that a fetch or install command must
explicitly state the version number to install. Instead, this goes to
the strategy used by OS package managers: Install the latest until told
to do otherwise.
Closes#1198
This performs a relatively weak in-memory translation of index file
data. It does not, in most cases, write the corrected data to disk, and
it emits a warning directly to STDERR each time it loads a deprecated
index.
Known limitations:
- It cannot recover certain bogus records that earlier alpha releases
generated (notably, where all chartfile data is missing)
- In some cases, it has to parse a filename to get version info. This is
lossy.
- Because it takes three passes through the YAML and JSON unmarshal, it
is not performant.
This feature is transitional and should be removed during the Beta
cycle, prior to the release of 2.0.0.
Closes#1265
There was a bug in the repo tests that caused them to overwrite the
repositories.yaml file in that directory. Now, the entire tests (server
and client-side) run inside of a temp directory.
This implements a new index file format for repository indices. It also
implements a new format for requirements.yaml.
Breaking change: This will break all previous versions of Helm, and will
impact helm search, repo, serve, and fetch functions.
Closes#1197
This also refactors significant portions of the CLI, moving much of the
shared code into a library.
Also in this release, a testing repository server has been added.
