2023-08-02Merge branch 'bb/use-trace2-counters-for-fsync-stats'Junio C Hamano1-0/+10
Instead of inventing a custom counter variables for debugging, use existing trace2 facility in the fsync customization codepath. * bb/use-trace2-counters-for-fsync-stats: wrapper: use trace2 counters to collect fsync stats
2023-07-20wrapper: use trace2 counters to collect fsync statsBeat Bolli1-0/+10
As mentioned in the thread starting at [1], trace2 counters should be used to count events instead of ad-hoc static variables. Convert the two fsync static variables to trace2 counters, reducing the coupling between wrapper.c and the trace2 subsystem. Adjust t/t5351 to match the trace2 counter output format. The counters are not per-thread because the ones being replaced also were not.

2023-07-10refs/packed-backend.c: add trace2 counters for jump listTaylor Blau1-0/+5
The previous commit added low-level tests to ensure that the packed-refs iterator did not enumerate excluded sections of the refspace. However, there was no guarantee that these sections weren't being visited, only that they were being suppressed from the output. To harden these tests, add a trace2 counter which tracks the number of regions skipped by the packed-refs iterator, and assert on its value.

2023-02-23treewide: remove unnecessary cache.h includes in source filesElijah Newren1-1/+1
We had several C files include cache.h unnecessarily. Replace those with an include of "git-compat-util.h" instead. Much like the previous commit, these have all been verified via both ensuring that gcc -E $SOURCE_FILE | grep '"cache.h"' found no hits and that make DEVELOPER=1 ${OBJECT_FILE_FOR_SOURCE_FILE} successfully compiles without warnings.

2022-10-24trace2: add global counter mechanismJeff Hostetler1-0/+101
Add global counters mechanism to Trace2. The Trace2 counters mechanism adds the ability to create a set of global counter variables and an API to increment them efficiently. Counters can optionally report per-thread usage in addition to the sum across all threads. Counter events are emitted to the Trace2 logs when a thread exits and at process exit. Counters are an alternative to `data` and `data_json` events. Counters are useful when you want to measure something across the life of the process, when you don't want per-measurement events for performance reasons, when the data does not fit conveniently within a region, or when your control flow does not easily let you write the final total. For example, you might use this to report the number of calls to unzip() or the number of de-delta steps during a checkout.
