|
||||
Previous code sometimes confused debuginfod with concurrent queries
|
||||
targeting the same RPM. One thread fetching & prefetching, the other
|
||||
thread misinterpreted the sudden presence of its target file in the
|
||||
fdcache as a mere unnecessary prefetch duplicate. But if it was the
|
||||
other thread's target file, previous code would -skip- it completely,
|
||||
resulting in a 404 error. New code allows the other thread to also
|
||||
decompress the target file and return it, and still continue to its
|
||||
own prefetching process for other files.
|
||||
|
||||
There's a performance trade-off here. Another option would be for the
|
||||
other thread to check the fdcache regularly and abort its own
|
||||
prefetch/fetch/prefetch loop early in case of a sudden target file
|
||||
hit. That'd save CPU probably but it'd stop prefetching of later
|
||||
segments of the input archive, which could save future time.
|
||||
|
||||
Automated testing is too time/load sensitive to attempt. Confirmed
|
||||
working with Martin's stress tester.

Subject: [PATCH] Support nullglob in profile.*.in files
|
||||
|
||||
In openSUSE we have the following RPM checker that uses
|
||||
shopt -s nullglob:
|
||||
https://github.com/openSUSE/post-build-checks/blob/master/checks/50-check-libtool-deps#L31
|
||||
|
||||
The script loads all /etc/profile.d/*.sh files via source $FILE which
|
||||
can end up by stuck cat (with no arguments):
|
||||
|
||||
shopt -s nullglob ; cat "/etc/debuginfod"/*.urls
|
||||
(stuck)
