bitbake: utils: Use internal fetcher function to avoid duplication

2023-02-26T11:49:41+00:00

We currently have two lists of "proxy" or "fetcher" environment exports. Make the one in utils match the one on the fetcher which has a more complete list of variables now. (Bitbake rev: f9165a798a307a6f0fee120d5c3de660d3a44ae8) Signed-off-by: Richard Purdie

bitbake: bb/utils: include SSL certificate paths in export_proxies

2023-01-26T21:50:31+00:00

bb.utils.export_proxies() is a poor-man's alternative for the environment setup code in bb/fetch2, but it's used in several places where recipes want to download manually (such as cve-update-db-native). Notably, export_proxies() doesn't pass on the SSL certificate paths from the original environment, so if SSL_CERT_FILE needs to be set (for example, in a buildtools environment) then proxies work but SSL doesn't. In an ideal world export_proxies and the same logic in fetch2 would merge, but until then we can add the SSL_CERT_ variables and duplicate the basic logic: check the datastore first and then the original environment for variables. Also remove the return value as nothing ever checked it. [ YOCTO #15000 ] (Bitbake rev: c19035e8e71c419c5688a86bfc9c946c96f638e8) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

bitbake: lib/bb: Update thread/process locks to use a timeout

2023-01-05T11:50:17+00:00

The thread/process locks we use translate to futexes in Linux. If a process dies holding the lock, anything else trying to take the lock will hang indefinitely. An example would be the OOM killer taking out a parser process. To avoid bitbake processes just hanging indefinitely, add a timeout to our lock calls using a context manager. If we can't obtain the lock after waiting 5 minutes, hard exit out using os._exit(1). Use _exit() to avoid locking in any other places trying to write error messages to event handler queues (which also need locks). Whilst a bit harsh, this should mean we stop having lots of long running processes in cases where things are never going to work out and also avoids hanging builds on the autobuilder.

bitbake: bin/utils: Ensure locale en_US.UTF-8 is available on the system

2022-12-08T10:49:53+00:00

Get rid of the duplicate code and add extra check that the locale en_US.UTF-8 is available on the system. This new helper method is now located right above the method filter_environment() which sets LC_ALL environment variable to 'en_US.UTF-8'.

bitbake: utils: Allow to_boolean to support int values

2022-11-27T23:48:15+00:00

Some variables may be set as: X = 1 as well the more usual X = "1" so add support to to_boolean to handle this case. (Bitbake rev: ef9c033b011e68bbfedf7ddf118633c14388aaaf) Signed-off-by: Richard Purdie

bitbake: utils/ply: Update md5 to better report errors with hashlib

2022-10-26T11:32:08+00:00

In the case where hashlib is not available, the try would fail and fall through resulting in a backtrace on the usage of the 'sig'. The backtrace itself was confusing and made it difficult to determine what went wrong. Update the import to be in it's own try block with an appropriate message to indicate what went wrong. Note, the current version of ply all of this code has been restructured so this is not applicable upstream. Additionally, some versions of hashlib don't appear to implement the second FIPS related argument. Detect this and support both versions.

bitbake: utils: Add enable_loopback_networking()

2022-09-29T20:26:09+00:00

It can be used to enable the loopback interface, typically after calling disable_network(). Also correct a typo in a debug message. (Bitbake rev: 0d317209d4234c5f05a9fcdc13c52f502f104018) Signed-off-by: Mattias Jernberg Signed-off-by: Peter Kjellerstedt Signed-off-by: Richard Purdie

bitbake: utils: Pass lock argument in fileslocked

2022-08-31T09:40:07+00:00

Pass additional arguments in the fileslocked() context manager to the underlying lockfile() function. This allows the context manager to be used for any types of locks (non-blocking, shared, etc.) that the lockfile() function supports.

bitbake: siggen: Fix insufficent entropy in sigtask file names

2022-08-09T15:28:03+00:00

Signature generation uses mkstemp() to get a file descriptor to a unique file and then write the signature into it. However, the unique file name generation in glibc is based on the system timestamp, which means that with highly parallel builds it is more likely than one might expect expected that a conflict will occur between two different builder nodes. When operating over NFS (such as a shared sstate cache), this can cause race conditions and rare failures (particularly with NFS servers that may not correctly implement O_EXCL). The signature generation code is particularly susceptible to races since a single "sigtask." prefix used for all signatures from all tasks, which makes collision even more likely. To work around this, add an internal implementation of mkstemp() that adds additional truly random entropy to the file name to eliminate conflicts.
