The search/package query is typically very slow and can spend several
minutes timing out. The concept of loading all package meta data at once
is attractive, but given that the query regularly increases the runtime
of the script by an order of magnitude or more making individual calls
seems advantageous. These calls are already included in the cache which
means the initial request avoids the 10+ minute wait and repetitive calls
have no additional cost.
- re-implement list and adi commands using RequestSplitter
- numerous small cleanups and clarity improvements
- notably, adi now prints similar output to select when adding requests
- lxml is needed to provide more fully-featured xpath implementation
It is not uncommon for a request to be in a pending state which requires
action beyond the scope of the staging workflow, but does not make sense
to deny the request. For lack of a "postponed" or "pending" state on OBS
a sudo-state of "ignore" is provided for the staging workflow. The ignore
state will remove a request from the "list" and "adi" commands so as not
to be accidentally staged. This avoids the need for keeping a context of
what requests should be ignored in one's memory.
It is expected that an ignored request will have comments reflecting what
is to be done or one should be added via the -m option of ignore command.
The two slowest staging API calls are for information that rarely changes.
By caching the result the commands typically execute over twice as fast.
Going further can see improvements of an order of magnitude or more by
caching almost all the GET requests.
In contrast to osclib/memoize.py this cache operates at the HTTP request
level. This has several advantages:
- Caches the expensive part (ie the HTTP request). There are a number of
functions in osc.core and elsewhere that make the same API request, but
process the result differently which would require multiple API calls
using memoize.
- Handles cases were a loader function uses class attributes as input and
output and thus no relevant method parameters or return. An important
example is StagingAPI._generate_ring_packages().
- Storage is project aware which allows caches to be deleted when a project
is known to have changed.
- Due to project awareness, can utilize OBS /statistics/latest_updated API
call to determine which projects need to be expired.
The cache file structure is as follows:
- hostname(apiurl)
- project
- sha1(url)
- sha1(url)
See Cache.PATTERNS for changing the time to live (ttl) or add patterns to
be cached.
Since commit 295fcd we newly also require http_POST in order to
put a new file in place after accepting.
Also add quotes around the fakepkgname when injecting it into the kiwi file.
If the package was linked to Ring1 from Ring1, staging list command
should display it as Ring0 package ie. it's only be able to puts in
ring0 staging project. This is work out
https://progress.opensuse.org/issues/8266
With --split argument, staging adi command can splits each package to
different adi staging project, the argument can work by 'osc staging adi
--split' or 'osc staging adi --move --split'. Note that, it will be
ignore --by-develproject argument too.
