sstate: Improve move into place op and touch file

2020-01-13T13:07:01+00:00

Depending on the kernel and coreutils version, mv operations test for existence of files and can potentially race. It also leads to the file always changing which leads to potential problems if using and NFS share and there are other readers. Using ln instead means we don't overwrite the file if it already exists meaning other readers aren't disrupted and should work more reliably on NFS which is used for sstate on the autobuilder. Since we're not overwriting files, touch the file to show activity as would have been done it it were reused from sstate.

sstate: Handle sstate filenames longer than 255 characters

2020-01-06T23:54:39+00:00

Many filesystems can't cope with filenames longer that 255 characters. Add code to detect this and truncate non-essential elements of the filename to stay within the limit. [YOCTO #13268] (From OE-Core rev: 90cc3d1ed1a12294a2d3ac97c1ba528ab315605d) Signed-off-by: Richard Purdie

sstate: Merge file name generation into single function

2020-01-06T23:54:39+00:00

Move the task handling and extension handling into one common filename construction function. (From OE-Core rev: c0c158d38583648a801e959d91371f7b43a98da5) Signed-off-by: Richard Purdie

sstate: Improve SSTATE_PKG handling

2020-01-06T23:54:39+00:00

Move the task handling code into the SSTATE_PKGNAME variable using a temporary variable. This makes the code more understandable as as well as allowing the length of the final sstate filename to be more easily accesses for following patches.

sstate: Add extra directory level

2020-01-06T23:54:39+00:00

We're having speed issues on the autobuilder due to the numbers of files in sstate directories. We previously split these by the first two characters of the hash. This change extends this to split by the next two characters as well, creating more layers of directories. This should signifiantly speed up eSDK builds on the autobuilder as the current sstate layout simply isn't scaling there but addresses a general complaint. gen-lockedsig-cache needed to be updated for the new split level sstate. Also update tests for new layout. (From OE-Core rev: d05bde16bdad761ed8f4c0a48de60c649aa33e85) Signed-off-by: Richard Purdie

sstate: Ensure mkdir happens before mktemp

2019-12-11T11:59:49+00:00

This avoids a directory not present error. Fix a comment typo whilst here. (From OE-Core rev: 1360d8d7d99b70a80c8cdbc1fc6d9e6752483139) Signed-off-by: Richard Purdie

sstate: Ensure target sstate directory exists if unihash changes

2019-12-11T10:09:39+00:00

The previous patches meant the mkdir might no longer match the final target directory. Fix this. (From OE-Core rev: 0af4dae84099e8632a9ea6a4afdbea2f232bb170) Signed-off-by: Richard Purdie

sstate: Ensure SSTATE_PKG is reloaded when handling siginfo

2019-12-10T23:19:32+00:00

STATE_PKG may have been changed by sstate_report_unihash so don't cache the variable's value. (From OE-Core rev: be29a25400c4ea285ab3f588c5831f00ba5d4f63) Signed-off-by: Richard Purdie
